In the following description, the vehicle 10 is an electric vehicle, but the vehicle 10 may be a hybrid vehicle or a fuel cell vehicle as long as it is a vehicle mounted with a secondary battery that supplies electric power for traveling.

< First embodiment >

[ Integral Structure ]

Fig. 1 is a diagram showing a configuration example of a manufacturing management system (hereinafter referred to as a manufacturing management system) 1 of an electric vehicle according to a first embodiment. The manufacturing management system 1 is a system that makes a manufacturing plan for a battery (hereinafter, referred to as a secondary battery) mounted on the vehicle 10 and manages manufacturing of the electric vehicle. As shown in fig. 1, the manufacturing management system 1 includes a plurality of vehicles 10 and a center server (manufacturing management device for electric vehicles) 100.

The center server 100 makes a vehicle manufacturing plan based on information transmitted from a plurality of vehicles 10. The vehicle 10 communicates with the center server 100 via a network NW. The network NW includes, for example, the internet, WAN (Wide Area Network), LAN (Local Area Network), a provisioning device, a wireless base station, and the like.

The center server 100 makes, for example, a manufacturing plan regarding the manufacture of a plurality of vehicles. In the manufacturing plan, when the vehicle is manufactured, the mounted battery 40 is taken out of the vehicle 10, and the taken-out battery 40 is reused as the battery 40 mounted on the vehicle 10 of a new vehicle. The center server 100 makes a plan as to what vehicles are to be manufactured for a plurality of vehicles, for example. In the following description, the vehicle from which the battery 40 is taken out is referred to as a take-out target vehicle, and the vehicle to be manufactured is referred to as a manufacture target vehicle. The extraction target vehicle and the production target vehicle are examples of an extraction target electric vehicle and a production target electric vehicle, respectively.

[ Vehicle 10]

Fig. 2 is a diagram showing an example of the structure of the vehicle 10. As shown in fig. 2, the vehicle 10 includes, for example, a motor 12, a drive wheel 14, a brake device 16, vehicle sensors 20, PCU (Power Control Unit), a battery 40, a battery sensor 42 such as a voltage sensor, a current sensor, a temperature sensor, a communication device 50, a charging port 70, and a converter 72.

The motor 12 is, for example, a three-phase ac motor. The rotor of the motor 12 is coupled to a drive wheel 14. The motor 12 outputs power to the drive wheels 14 using the supplied electric power. The motor 12 uses the kinetic energy of the vehicle to generate electricity when the vehicle is decelerating.

The brake device 16 includes, for example, a caliper, a hydraulic cylinder that transmits hydraulic pressure to the caliper, and an electric motor that generates hydraulic pressure in the hydraulic cylinder. The brake device 16 may be provided with a mechanism for transmitting the hydraulic pressure generated by the operation of the brake pedal to the hydraulic cylinder via the master cylinder as a backup. The brake device 16 is not limited to the above-described configuration, and may be an electronically controlled hydraulic brake device that transmits the hydraulic pressure of a master cylinder to a hydraulic cylinder.

The vehicle sensor 20 includes an accelerator opening sensor, a vehicle speed sensor, and a brake pedal amount sensor. The accelerator opening sensor is attached to an accelerator pedal as an example of an operation tool that receives an acceleration instruction from a driver, detects an operation amount of the accelerator pedal, and outputs the detected operation amount as an accelerator opening to the control unit 36. The vehicle speed sensor includes, for example, a wheel speed sensor and a speed computer, which are mounted on each wheel, and the speeds of the wheels detected by the wheel speed sensor are combined to derive the speed (vehicle speed) of the vehicle, and the speed is output to the control unit 36. The brake pedal amount sensor is attached to the brake pedal, detects the operation amount of the brake pedal, and outputs the detected operation amount to the control unit 36 as the brake pedal amount.

The PCU30 includes, for example, converters 32 and VCU (Voltage Control Unit) and a control unit 36. These components are merely examples of the configuration in which the PCU34 is formed as a concentrated structure, and may be distributed.

The converter 32 is, for example, an AC-DC converter. The dc-side terminal of the converter 32 is connected to the dc link DL. A battery 40 is connected to the dc link DL via the VCU 34. The converter 32 converts ac power generated by the motor 12 into dc power and outputs the dc power to the dc link DL.

The VCU34 is, for example, a DC-DC converter. The VCU34 boosts the electric power supplied from the battery 40 and outputs the boosted electric power to the dc link DL.

The control unit 36 includes, for example, a motor control unit, a brake control unit, and a battery/VCU control unit. The motor control unit, the brake control unit, and the battery/VCU control unit may be replaced with separate control devices, for example, a motor ECU, a brake ECU, and a battery ECU.

The motor control unit controls the motor 12 based on the output of the vehicle sensor 20. The brake control section controls the brake device 16 based on the output of the vehicle sensor 20. The battery/VCU control unit calculates SOC (State Of Charge) of the battery 40 based on the output of the battery sensor 42 attached to the battery 40, and outputs the calculated result to the VCU 34. The VCU34 increases the voltage of the dc link DL in accordance with an instruction from the battery/VCU control unit.

The battery 40 is a secondary battery such as a lithium ion battery. The battery 40 stores electric power introduced from the charger 200 outside the vehicle 10, and discharges the vehicle 10 for running. The battery sensor 42 includes, for example, a current sensor, a voltage sensor, and a temperature sensor. The battery sensor 42 detects, for example, a current value, a voltage value, and a temperature of the battery 40. The battery sensor 42 outputs the detected current value, voltage value, temperature, and the like to the control unit 36 and the communication device 50.

As shown in fig. 3, the battery 40 includes a plurality of slots 40A, and the battery segments 41 are inserted into the slots 40A. When the electric storage amounts of the battery segments 41 are common, for example, the full capacity, the electric storage amounts of the batteries 40 differ according to the number of the battery segments 41 inserted into the slots 40A. The battery segment 41 is an example of a secondary battery segment.

For example, in the case where 4 battery segments 41 are inserted into the slot 40A, the amount of stored electricity increases as compared with the case where 2 battery segments 41 are inserted into the slot 40A. The number of battery segments 41 inserted into the slots 40A may be the same as the number of slots 40A or may be smaller than the number of slots 40A.

A cover (lid), not shown, for example, may be attached to the slot 40A, which is not inserted into the battery segment 41, so as to prevent the slot 40A from being exposed. When the number of battery segments 41 is smaller than the number of slots 40A, the battery segments 41 may be inserted into the slots 40A at positions determined by the number of battery segments 41, or the battery segments 41 may be inserted into any of the slots 40A.

In the embodiment, the battery 40 has the number of slots 40A that is sometimes greater than the number of the battery segments 41 inserted, but the battery 40 may have the same number of slots as the number of the battery segments 41 inserted. The slot 40A may be covered by a cover (lid) or the like as a whole.

The communication device 50 includes a wireless module for connecting to a cellular network or Wi-Fi network. The communication device 50 acquires battery usage state information such as a current value, a voltage value, and a temperature output from the battery sensor 42 for each battery segment 41, and transmits the battery usage state information to the center server 100 via the network NW shown in fig. 1.

The charging port 70 is provided toward the outside of the vehicle body of the vehicle 10. The charging port 70 is connected to the charger 200 via a charging cable 220. The charging cable 220 includes a first plug 222 and a second plug 224. The first plug 222 is connected to the charger 200, and the second plug 224 is connected to the charging port 70. The electric power supplied from the charger 200 is supplied to the charging port 70 via the charging cable 220.

The charging cable 220 includes a signal cable attached to the power cable. The signal cable mediates communication between the vehicle 10 and the charger 200. Accordingly, a power connector and a signal connector are provided at the first plug 222 and the second plug 224, respectively.

The converter 72 is provided between the charging port 70 and the battery 40. The converter 72 converts a current, for example, an alternating current, introduced from the charger 200 via the charging port 70 into a direct current. The converter 72 outputs the converted dc current to the battery 40.

[ Central Server 100]

The center server 100 shown in fig. 1 includes, for example, an acquisition unit 110, a planning unit 120, an output unit 130, a storage unit 150, and an output device 180. The acquisition unit 110, the planning unit 120, and the output unit 130 are implemented by executing a program (software) by a hardware processor such as CPU (Central Processing Unit), for example. Some or all of these components may be realized by hardware (including a circuit part) such as LSI (LARGE SCALE Integration) or ASIC(Application Specific Integrated Circuit)、FPGA(Field-Programmable Gate Array)、GPU(Graphics Processing Unit), or may be realized by cooperation of software and hardware. The program may be stored in advance in a storage device (non-transitory storage medium) such as HDD (Hard Disk Drive) or a flash memory, or may be stored in a removable storage medium (non-transitory storage medium) such as a DVD or a CD-ROM, and installed by mounting the storage medium on a drive device. The storage unit 150 is implemented by the aforementioned storage device.

The acquisition unit 110 receives and acquires information such as a current value, a voltage value, a temperature, and a lifetime of the battery segment 41 in the battery 40 transmitted from each of the plurality of vehicles 10. The acquisition unit 110 acquires the degradation state of the battery segment 41 in the battery 40 mounted on each vehicle based on the acquired information. The acquisition unit 110 collects the degradation states of the battery segments 41 acquired, and collects the collected data 151 for each vehicle type of the vehicle 10 on which the battery 40 is mounted and each degradation degree of the battery segments 41, and stores the collected data in the storage unit 150.

Fig. 4 is a diagram showing an example of the collected data 151. As shown in fig. 4, the collected data 151 is data obtained by classifying and grouping the number of battery segments 41 taken out from the vehicle 10 according to each degradation degree. The collected data 151 classifies the battery segments 41 classified according to the respective degrees of deterioration according to the respective types of vehicles serving as new pickup sources.

The data grouped as collected data 151 may be defined as a battery segment 41 detached from the vehicle 10. Or may include a battery segment 41 that is currently mounted on the vehicle 10 but is later detached from the vehicle 10 and reused for the manufacture of other vehicles. The future time may be, for example, a time when a manufacturing plan of the vehicle is newly created, or a time when the vehicle is manufactured in accordance with the manufacturing plan.

As the degradation degree of the battery segment 41, for example, a range of 0% to 10%, more than 10% to 30%, more than 30% to 40% is defined. The battery segment having a degradation degree exceeding 40% is excluded from the management targets because the amount of electric power required for the battery segment mounted on the vehicle 10 is not satisfied. The battery segments having a higher degradation degree may be the management object, or all the battery segments may be the management object.

As the vehicle type, for example, a vehicle type "X" having a long traveling range, for example, about 1200km, a vehicle type "Y" having a medium traveling range, for example, about 600km, and a vehicle type "Z" having a short traveling range, for example, about 300km are prescribed. The set value of the amount of stored electricity in the battery 40 mounted on the vehicle 10 is determined, for example, from the travel range. For example, the set value of the electric storage amount of the battery 40 mounted on the vehicle model "X" having a long travel range is larger than the set value of the electric storage amount of the battery 40 mounted on the vehicle model "Y" having a medium travel range. The set value of the electric storage amount of the battery 40 mounted on the vehicle model "Y" having a moderate traveling range is larger than the set value of the electric storage amount of the battery 40 mounted on the vehicle model "Z" having a short traveling range.

The obtaining unit 110 obtains the number of manufactured vehicles of each vehicle type, which is input by an input device, not shown, for example. The number of vehicles to be manufactured is used when generating a manufacturing plan for the vehicle. The input device is provided in the center server 100, for example. The acquisition unit 110 may acquire information on the number of manufacturing stations provided by other devices via communication or the like.

The planning unit 120 makes a manufacturing plan for manufacturing a vehicle as a new vehicle. In the manufacturing plan, plan data 152 indicating the number of manufactured vehicles of each model and the supply source of the battery segments to be supplied as the batteries 40 mounted on each vehicle are generated. Fig. 5 is a diagram showing an example of the plan data 152. As shown in fig. 5, the plan data 152 includes various items of a vehicle model, the number of manufacturing stations, the number of required segments, the required degradation degree, and a segment supply source.

The vehicle model is common to the collected data 151. When the manufacturing plan is made, vehicle types other than these vehicle types may be included. In this case, the degradation degree of the battery segment 41 is also collected by the collection data 151 regarding the vehicle model included in the manufacturing plan. The item of the number of manufacturing stations indicates the number of vehicles planned to be manufactured. For example, vehicles of the vehicle type "X" having a long traveling range tend to be expensive and have a limited number of sales. Therefore, the number of vehicle manufacturing stations of the vehicle model "X" is set to 500, which is relatively small. The price of the vehicle type "Y" having a middle traveling range is middle, and therefore the number of the vehicles manufactured is 2000, and the price of the vehicle type "Z" having a short traveling range is relatively low, and therefore the number of the vehicles manufactured is 5000, which is relatively large. The travel range is a design value of the distance that the vehicle 10 can travel when the battery 40 is fully charged.

The number of segments required is the number of battery segments required for manufacturing the planned number of vehicles (required number). For example, since the vehicle of the vehicle type "X" is a vehicle having a long traveling range, the number of battery segments required for 1 vehicle is 4 or so. Therefore, the number of required segments for manufacturing a 500-vehicle model "X" vehicle becomes 2000.

Since the vehicle of the vehicle type "Y" is a vehicle having a medium traveling range, the number of battery segments required for 1 is 2, and the number is smaller than that of the vehicle type "X". Therefore, the number of required segments for manufacturing a 2000 vehicle model "Y" becomes 4000. Since the vehicle of the vehicle type "Z" has a short traveling range, the number of 1 battery segments required for 1 vehicle is 1, and the number of vehicles is smaller than that of the vehicle type "Y". Therefore, the number of segments required for manufacturing a 5000 vehicle model "Z" becomes 5000.

The required degradation degree is a degradation degree of the battery segment required for the model of the manufactured vehicle, and is predetermined for each model. For example, since the vehicle of the vehicle type "X" has a long traveling range, the required amount of electric storage of the battery is large, and the required degree of deterioration of the battery segment is reduced accordingly. Specifically, the degree of degradation required for a vehicle of the vehicle model "X" is 10% or less.

The travel range of the vehicle model "Y" is medium, and the required amount of stored electricity of the battery and the required degree of deterioration of the battery segment are also medium. Specifically, the degree of degradation required for a vehicle of the model "Y" is 30% or less. The vehicle of the vehicle type "Z" has a short travel range, and the required amount of stored electricity of the battery and the required degree of deterioration of the battery segment also increase to some extent. Specifically, the degree of degradation required for a vehicle of the vehicle model "Z" is 40% or less.

The segment supply source represents a planned value of the vehicle model of the vehicle to be taken out and the number of battery segments to be taken out, and a planned value of the number of battery segments to be manufactured for a new product. The battery mounted on the vehicle to be manufactured is already mounted on the vehicle to be removed, and includes a battery segment (hereinafter referred to as a mounted battery segment) removed from the vehicle to be removed and a battery segment (hereinafter referred to as a new battery segment) newly manufactured in a factory or the like. The segment supply source classifies and indicates a planned value of the number of removed battery segments (hereinafter referred to as a planned value of the removed battery segments) and a planned value of the number of manufactured new battery segments (hereinafter referred to as a planned value of the new battery segments) for each type of the vehicle to be removed. The battery mounted on the vehicle to be removed is a secondary battery to be removed, and the battery mounted on the vehicle to be manufactured is a secondary battery to be manufactured.

For example, among the battery segments supplied to the vehicle to be manufactured of the vehicle model "X", the planned values of the mounted battery segments of the vehicle to be removed mounted on the vehicle model "X" are 95, the planned values of the mounted battery segments of the vehicle to be removed mounted on the vehicle model "Y" are 4, and the planned values of the mounted battery segments of the vehicle to be removed mounted on the vehicle model "Z" are 1. Since the number of required segments of the vehicle model "X" is 2000 and the planned value of the mounted battery segments is 100, the planned value of a new battery segment among the battery segments supplied to the manufacturing target vehicle of the vehicle model "X" is 1900.

Of the battery segments supplied to the vehicle to be manufactured of the vehicle model "Y", the planned values of the mounted battery segments of the vehicle to be removed mounted on the vehicle model "X" are 700, the planned values of the mounted battery segments of the vehicle to be removed mounted on the vehicle model "Y" are 1950, and the planned values of the mounted battery segments of the vehicle to be removed mounted on the vehicle model "Z" are 1350. Of the battery segments supplied to the vehicle to be manufactured of the vehicle model "Z", the planned values of the mounted battery segments of the vehicle to be removed mounted on the vehicle model "X" are 1200, the planned values of the mounted battery segments of the vehicle to be removed mounted on the vehicle model "Y" are 2900, and the planned values of the mounted battery segments of the vehicle to be removed mounted on the vehicle model "Z" are 1900. The planned values of the battery segments supplied to the manufacturing target vehicles of the vehicle model "Y" and the vehicle model "Z" are all provided by the mounted battery segments. Therefore, the planned value of the new battery segment to be supplied to the manufacturing target vehicle of the model "Y" and model "Z" is 0.

The planning unit 120 determines a planned value of the segment supply source and the installed battery segment using the vehicle model and the number of manufactured vehicles existing in the manufacturing plan, the collection data 151, and the like. The procedure of determining the planned values of the segment supply sources and the mounted battery segments will be described with reference to the processing of the center server 100.

The output unit 130 controls the output device 180 to output predetermined information from the output device 180. The output device 180 includes, for example, a display device for displaying information such as a monitor, a speaker for outputting information based on sound, a printer for printing information, and an output control device for controlling these display device, speaker, and printer. The output device 180 outputs manufacturing plan information that matches the plan data 152 planned by the planning unit 120, according to the control of the output unit 130. The output device 180 may be configured to output the manufacturing plan information in the center server 100 via a display device or the like, or may be configured to output the manufacturing plan information to another device, for example, a communication device provided in the vehicle 10, using a communication device.

Next, the processing of the center server 100 will be described. Fig. 6 to 8 are flowcharts showing an example of the processing performed by the center server 100. The center server 100 generates collection data 151 obtained by classifying and grouping the battery segments 41 in the batteries 40 mounted on the plurality of vehicles 10 according to the respective degradation degrees. The central server 100 generates planning data 152 using the generated collection data 151. The procedure for generating the collected data 151 will be described below with reference to fig. 6.

The acquisition unit 110 in the center server 100 determines whether or not battery usage status information of each battery segment 41 transmitted through the vehicle 10 is received (step S101). When it is determined that the battery usage status information is not received, the center server 100 ends the processing shown in fig. 6.

When it is determined that the battery usage information is received, the planning unit 120 calculates the degradation degree of the battery segment 41 based on the transmitted battery usage information (step S103). In calculating the degradation degree of the battery segment 41, for example, mechanical learning may be performed in which data on the battery usage conditions of the battery segment 41 transmitted through a plurality of vehicles, etc. are collected as learning data, and the degradation degree of the battery segment 41 may be calculated using the result of the mechanical learning.

Next, the planning unit 120 updates the collection data 151 based on the calculated degradation degree of the battery segment 41 (step S105). In this way, the center server 100 ends the processing shown in fig. 6. The center server 100 can generate the collected data 151 in which the plurality of battery segments 41 are classified according to each degradation degree by updating the collected data 151 by the flow shown in fig. 6 every time the battery usage status information is transmitted through the plurality of vehicles 10.

Next, the procedure of generating the plan data 152 will be described with reference to fig. 7 and 8. First, the obtaining unit 110 obtains the number of manufactured vehicles of each model of the vehicle inputted through an input device (not shown) (step S201). Next, the acquisition unit 110 reads the collection data 151, and acquires the number of mounted battery segments (hereinafter referred to as the number of mounted segments) taken out from the vehicle to be taken out (step S203). The acquisition unit 110 acquires the number of mounted segments for each degradation degree.

Next, the planning unit 120 generates planning data 152 based on the number of manufactured models of the vehicle and the number of mounted segments of each degradation degree acquired by the acquisition unit 110 (step S205). The order in which the planning data 152 is generated will be described later. Then, the output unit 130 causes the output device 180 to output the manufacturing plan information that matches the plan data 152 planned by the planning unit 120 (step S207). In this way, the center server 100 ends the processing shown in fig. 7.

Next, the procedure of generating the plan data 152 will be described with reference to fig. 8. The planning unit 120 determines whether or not the number of mounted battery segments with a degradation degree of 30 to 40% is equal to or greater than the number of segments required for the vehicle to be manufactured of the vehicle model "Z" (step S211). For example, when the number of required segments of the vehicle to be manufactured of the vehicle model "Z" is 5000, it is determined whether or not the number of mounted battery segments having a degradation degree of 30% to 40% is 5000 or more.

When it is determined that the number of mounted battery segments having a degradation degree of 30% to 40% is equal to or greater than the number of segments required for the vehicle to be manufactured of the vehicle type "Z", the planning unit 120 sets the planned value of the mounted battery segments having a degradation degree of 30% to 40% to be supplied to the vehicle to be manufactured of the vehicle type "Z" to the same number as the number of segments required for the vehicle to be manufactured of the vehicle type "Z" (step S213). For example, when the number of segments required for the vehicle to be manufactured in the vehicle model "Z" is 5000, the planned value of the mounted battery segments having a degradation degree of 30% to 40% is 5000.

The supply source of the planned value of the mounted battery segment with the degradation degree of 30% to 40% can be appropriately determined. For example, the battery segment 41 mounted on the vehicle model "X" may be prioritized, or the battery segment removed from the vehicle to be taken out may be prioritized earlier. Or may be determined entirely at random, or the battery segment 41 that is geographically easy to handle may be prioritized between the factory where the vehicle 10 is manufactured and the location where the battery segment 41 is provided, or the like.

If it is determined in step S211 that the number of mounted battery segments having a degradation degree of 30% to 40% is not equal to or greater than the number of required segments of the vehicle to be manufactured of the vehicle type "Z", the planning unit 120 determines whether or not the number of mounted battery segments having a degradation degree of 10% to 40% is equal to or greater than the number of required segments of the vehicle to be manufactured of the vehicle type "Z" (step S215). For example, when the number of required segments of the vehicle to be manufactured of the vehicle model "Z" is 5000, it is determined whether or not the number of mounted battery segments having a degradation degree of 10% to 40% is 5000 or more.

When it is determined that the number of mounted battery segments having a degradation degree of 10% to 40% is equal to or greater than the number of segments required for the vehicle to be manufactured of the vehicle type "Z", the planning unit 120 sets the planned value of the mounted battery segments having a degradation degree of 10% to 40% to be supplied to the vehicle to be manufactured of the vehicle type "Z" to the same number as the number of segments required for the vehicle to be manufactured of the vehicle type "Z" (step S217). At this time, the number of mounted battery segments having a high degradation degree of 30 to 40% is included in the planned value of the mounted battery segments having a degradation degree of 10 to 40% supplied to the manufacturing target vehicle of the vehicle model "Z", and the remaining part thereof is provided by the planned value of the mounted battery segments having a degradation degree of 10 to 30% supplied to the manufacturing target vehicle of the vehicle model "Z".

For example, when the number of required segments of the vehicle to be manufactured of the vehicle model "Z" is 5000, the number of mounted battery segments having a degradation degree of 30% to 40% is 3000, and the number of mounted battery segments having a degradation degree of 10% to 30% is 3000. In this case, the planned values of the mounted battery segments having a degradation degree of 30% to 40% are 3000, and the planned values of the mounted battery segments having a degradation degree of 10% to 30% are 2000. When the mounted battery segments having different degradation degrees can be determined, the mounted battery segment having a large degradation degree is preferentially determined.

When it is determined in step S215 that the number of mounted battery segments having a degradation degree of 10% to 40% is not equal to or greater than the number of required segments of the vehicle to be manufactured of the vehicle type "Z", the planning unit 120 determines whether or not the number of mounted battery segments having a degradation degree of 40% or less is equal to or greater than the number of required segments of the vehicle to be manufactured of the vehicle type "Z" (step S219). For example, when the number of required segments of the vehicle to be manufactured of the vehicle model "Z" is 5000, it is determined whether or not the number of mounted battery segments having a degradation degree of 40% or less is 5000 or more.

When it is determined that the number of mounted battery segments having a degradation degree of 40% or less is equal to or greater than the number of segments required for the vehicle to be manufactured of the vehicle type "Z", the planning unit 120 sets the planned value of the mounted battery segments having a degradation degree of 40% or less to be supplied to the vehicle to be manufactured of the vehicle type "Z" to the same number as the number of segments required for the vehicle to be manufactured of the vehicle type "Z" (step S221). In this case, the number of mounted battery segments having a high degradation degree of 10% to 40% is included in the planned value of the mounted battery segments having a degradation degree of 40% or less supplied to the vehicle to be manufactured of the vehicle model "Z", and the remaining part thereof is provided by the planned value of the mounted battery segments having a degradation degree of 10% or less supplied to the vehicle to be manufactured of the vehicle model "Z".

When it is determined in step S219 that the number of mounted battery segments having a degradation degree of 40% or less is not equal to or greater than the number of segments required for the vehicle to be manufactured of the vehicle model "Z", the planning unit 120 includes the total number of mounted battery segments in the planned value of the mounted battery segments, and the remaining part thereof is supplied with the planned value of the new battery segment (step S223). Through the processing of steps S211 to S223 up to this point, the supply source of the battery segment and the planned value of the battery segment for the vehicle to be manufactured of the vehicle model "Z" are generated.

Next, the planning unit 120 determines whether or not the remaining number of mounted battery segments with a degradation degree of 10% to 30% is equal to or greater than the number of segments required for the vehicle to be manufactured of the vehicle model "Y" (step S231). The remaining number of mounted battery segments having a degradation degree of 10% to 30% is a value obtained by subtracting a planned value of mounted battery segments having a degradation degree of 10% to 30% supplied to the manufacturing target vehicle of the vehicle model "Z" from the number of mounted battery segments having a degradation degree of 10% to 30%. For example, when the number of required segments of the vehicle to be manufactured of the vehicle model "Y" is 4000, it is determined whether or not the remaining number of mounted battery segments having a degradation degree of 10% to 30% is 4000 or more.

When it is determined that the remaining number of mounted battery segments having a degradation degree of 10% to 30% is equal to or greater than the number of segments required for the vehicle to be manufactured of the vehicle model "Y", the planning unit 120 sets the planned value of the mounted battery segments having a degradation degree of 10% to 30% to be supplied to the vehicle to be manufactured of the vehicle model "Y" to the same number as the number of segments required for the vehicle to be manufactured of the vehicle model "Y" (step S233). For example, when the number of required segments of the vehicle to be manufactured of the vehicle model "Y" is 4000, the planned value of the mounted battery segment having a degradation degree of 10% to 30% is 4000.

When it is determined in step S231 that the remaining number of mounted battery segments having a degradation degree of 10% to 30% is not equal to or greater than the required number of segments of the vehicle to be manufactured of the vehicle type "Y", the planning unit 120 determines whether or not the remaining number of mounted battery segments having a degradation degree of 30% or less is equal to or greater than the required number of segments of the vehicle to be manufactured of the vehicle type "Y" (step S235). For example, when the number of required segments of the vehicle to be manufactured of the vehicle model "Y" is 4000, it is determined whether or not the remaining number of mounted battery segments having a degradation degree of 30% or less is 4000 or more.

When it is determined that the remaining number of mounted battery segments having a degradation degree of 30% or less is equal to or greater than the number of segments required for the vehicle to be manufactured of the vehicle model "Y", the planning unit 120 sets the planned value of the mounted battery segments having a degradation degree of 30% or less to be supplied to the vehicle to be manufactured of the vehicle model "Y" to the same number as the number of segments required for the vehicle to be manufactured of the vehicle model "Y" (step S237). In this case, the number of mounted battery segments having a high degradation degree of 10% to 30% is included in the planned value of the mounted battery segments having a degradation degree of 30% or less supplied to the manufacturing target vehicle of the vehicle model "Y", and the remaining part thereof is supplied with the planned value of the mounted battery segments having a degradation degree of 10% or less supplied to the manufacturing target vehicle of the vehicle model "Y".

When it is determined in step S235 that the number of mounted battery segments having a degradation degree of 30% or less is not equal to or greater than the number of segments required for the vehicle to be manufactured of the vehicle model "Y", the planning unit 120 includes the total number of mounted battery segments having a degradation degree of 30% or less in the planned value of the mounted battery segments, and the remaining part thereof is supplied with the planned value of the new battery segment (step S239). Through the processing of steps S231 to S239 up to this point, the supply source of the battery segment and the planned value of the battery segment for the vehicle to be manufactured of the vehicle model "Y" are generated.

Next, the planning unit 120 determines whether or not the remaining number of mounted battery segments having a degradation degree of 10% or less is equal to or greater than the number of segments required for the manufacturing target vehicle of the vehicle model "X" (step S251). For example, when the number of required segments of the vehicle to be manufactured of the vehicle model "X" is 2000, it is determined whether or not the remaining number of mounted battery segments having a degradation degree of 10% or less is 2000 or more.

When it is determined that the remaining number of mounted battery segments having a degradation degree of 10% or less is equal to or greater than the number of segments required for the vehicle to be manufactured of the vehicle type "X", the planning unit 120 sets the planned value of the mounted battery segments having a degradation degree of 10% or less to be supplied to the vehicle to be manufactured of the vehicle type "X" to the same number as the number of segments required for the vehicle to be manufactured of the vehicle type "X" (step S253). When it is determined that the number of mounted battery segments having a degradation degree of 10% or less is not equal to or greater than the number of segments required for the vehicle to be manufactured of the vehicle model "X", the planning unit 120 includes the total number of mounted battery segments having a degradation degree of 10% or less in the planned value of the mounted battery segments, and the remaining part thereof is provided by the planned value of the new battery segment (step S255). Through the processing of steps S251 to S255 up to this point, the supply source of the battery segment and the planned value of the battery segment for the vehicle to be manufactured of the vehicle model "X" are generated. In this way, the center server 100 ends the processing shown in fig. 8.

Next, a change in the vehicle to be the mounting destination of the battery segment 41 will be described. Fig. 9 is a diagram showing an example of a change in the vehicle to be the mounting destination of the battery segment. For example, the battery 40 manufactured as a new product in the factory M or the like is mounted on the long-travel-range vehicle 10X of the vehicle type "X". In the long travel range vehicle 10X, 4 battery segments 41 are mounted to constitute a battery 40.

When the battery segment 41 mounted on the long-range vehicle 10X is degraded, it is detached from the long-range vehicle 10X and mounted on, for example, the medium-range vehicle 10Y. In the medium-range vehicle 10Y, 2 battery segments 41 are mounted to constitute a battery 40. Therefore, for example, the calculation of the battery segments 41 among the batteries 40 providing 6 medium-range vehicles 10Y by 3 battery segments 41 after use in the long-range vehicle 10X is performed.

At this time, when the battery segments 41 are degraded by, for example, about 20% to 30%, the travel range of the medium travel range vehicle 10Y is shortened as compared with the travel range of about 420 km to 480km when the battery segments 41 are mounted without degradation, for example, about 600 km.

As the battery segment 41 used in manufacturing the long-travel-range vehicle 10X, a battery segment 41 having a very low degradation degree of 10% or less is required. Therefore, as the battery segment 41 mounted on the long-travel-range vehicle 10X, an already-mounted battery segment may be used as the battery segment 41, but most of them use a new battery segment 41 manufactured in the factory M.

When 12 battery segments 41 are removed from 3 long travel range vehicles 10X, for example, the degradation degree of each of the 12 battery segments 41 is determined, and a combination of 2 battery segments 41 having equal degradation degrees is determined and mounted as a battery 40 on the medium travel range vehicle 10Y. For example, the degradation degree of the first battery segment 41A shown in fig. 9 is 10%, the degradation degree of the second battery segment 41B is 40%, the degradation degree of the third battery segment 41C is 20%, and the degradation degree of the fourth battery segment 41D is 30%. In this case, for example, a combination of the first battery segment 41A and the second battery segment 41B is determined, and the combination of the third battery segment 41C and the fourth battery segment 41D is determined as the battery 40 to be mounted on 1 medium-traveling-range vehicle 10Y, and the combination is mounted as the battery 40 to be mounted on 1 medium-traveling-range vehicle 10Y. Thus, the battery 40 having a degradation degree of 25% on average is mounted in any of the medium-traveling-range vehicles 10Y, and the performance can be equalized.

When the battery segment 41 mounted on the medium travel range vehicle 10Y is further deteriorated, it is detached from the medium travel range vehicle 10Y and mounted on, for example, the short travel range vehicle 10Z. In the short travel range vehicle 10Z, 1 battery segment 41 is mounted to constitute the battery 40. Therefore, for example, the calculation of the battery segment 41 among the batteries 40 providing the 12 short travel range vehicles 10Z by the 3 battery segments 41 after use in the long travel range vehicles 10X is performed.

At this time, when the battery segments 41 are degraded from the initial values by about 30% to 40%, for example, the traveling range of the short traveling range vehicle 10Z is further shortened than when the non-degraded battery segments 41 are mounted, for example, the traveling range of 300km is about 180km to 210 km.

The number of battery segments 41 mounted on each long travel range vehicle 10X is greater than the number of battery segments 41 mounted on each medium travel range vehicle 10Y or short travel range vehicle 10Z. On the other hand, the sales count of the long-travel-range vehicle 10X tends to be smaller than the sales count of the medium-travel-range vehicle 10Y or the short-travel-range vehicle 10Z. The same tendency can be observed between the medium-travel-range vehicle and the short-travel-range vehicle. Therefore, when the battery segment 41 after use in the long-range vehicle 10X is mounted on the medium-range vehicle 10Y or when the battery segment 41 after use in the medium-range vehicle 10Y is mounted on the short-range vehicle 10Z, the supply-demand relationship can be easily adjusted.

Next, a method for manufacturing a vehicle to be manufactured using a battery segment taken out from a vehicle to be taken out according to a vehicle manufacturing plan generated by the center server 100 will be described. Each time the manufacturing target vehicle is manufactured, the number of battery segments 41 taken out from the take-out target vehicle is prepared to comply with the manufacturing plan. The battery segment 41 in this case may be a battery segment at the time of taking out the vehicle to be taken out from the vehicle to be taken out at the place of manufacturing the vehicle to be manufactured, or the battery segment 41 taken out from the vehicle to be taken out and stored in advance may be taken in.

After the battery segment 41 is prepared, the production of vehicles conforming to the number of vehicle types of the production schedule is started. In the process of manufacturing each manufacturing target vehicle, the battery segment 41 is inserted into the slot 40A (fig. 3) of the battery 40 of the manufacturing target vehicle. Here, when the manufacturing target vehicle is a long travel range vehicle, the battery segments 41 are inserted into all 4 slots 40A. In the case where the manufacturing target vehicle is a medium travel range vehicle, the battery segment 41 is inserted into 2 slots 40A among the 4 slots 40A. In the case where the manufacturing target vehicle is a short travel range vehicle, the battery segment 41 is inserted into 1 slot 40A of the 4 slots 40A.

The battery segment 41 attached to the vehicle to be manufactured is, for example, a battery segment attached to a vehicle to be taken out, the set value of the stored electric power being larger than that of the vehicle to be manufactured. For example, the battery segment 41 mounted on the medium travel range vehicle 10Y is the battery segment 41 mounted on the long travel range vehicle 10X. At this time, the battery segment 41 attached to the long-travel-range vehicle 10X is a new battery segment manufactured in a factory or the like, for example.

For example, more battery segments 41 than the production target vehicle are mounted on the removal target vehicle. For example, when the battery segments 41 attached to the long-range vehicle 10X are attached to the medium-range vehicle 10Y, 4 battery segments 41 are mounted on the long-range vehicle 10X, and 2 battery segments 41 are mounted on the medium-range vehicle 10Y.

Then, the number of vehicles to be manufactured in accordance with the manufacturing plan is manufactured through the manufacturing steps at each place. The manufacturing target vehicle may be manufactured sequentially according to the time when each model is changed, or a plurality of models may be manufactured simultaneously.

According to the first embodiment described above, the battery segment 41 to be reused as the manufacturing target vehicle is determined based on the degree of degradation of the battery segment 41 taken out from the vehicle to be taken out. For example, the battery segment 41 taken out from the long-travel-range vehicle 10X is used as the battery segment 41 having a small degradation degree, and the battery segment 41 having a large degradation degree is used as the battery segment of the short-travel-range vehicle 10Z. Accordingly, a secondary battery compatible with the performance of the vehicle can be manufactured and provided. In the vehicle 10 compatible with the set value of the battery 40, the reused battery 40, particularly, the new battery 40 can be appropriately provided by being reused, so that the use efficiency of the battery 40 can be improved, and the battery 40 and the battery segment 41 that meet the demand can be provided at low cost. Since the battery 40 is configured to include the battery segments 41, the battery 40 can be divided into the battery segments 41 for reuse.

By generating the collected data 151, data relating to the battery 40 can be stored for a long period of time, and the battery 40 can be replaced at an appropriate timing with respect to the vehicle 10. In the long travel range vehicle 10X, for example, a new battery 40 is supplied, and the battery 40 whose degradation progresses and whose stored electric power decreases is supplied to the medium travel range vehicle 10Y or the short travel range vehicle 10Z, so that it is possible to realize secondary use of the battery 40 and appropriately supply the battery 40 commensurate with the travel ranges of the respective vehicles.

In the first embodiment, the battery 40 is taken out from the vehicle to be taken out or mounted on the manufacturing vehicle in units of the battery segment 41, but the battery 40 may be taken out from the vehicle to be taken out or mounted on the manufacturing vehicle directly. The battery segments 41 may not be one by one but may be a plurality of pieces together into 1 unit.

< Second embodiment >

Next, a second embodiment will be described. Fig. 10 is a diagram showing a configuration example of the manufacturing management system 1 according to the second embodiment. The configuration of the second embodiment differs from the configuration of the first embodiment in that the center server 100 is provided with a request unit 140. When the number of required battery segments 41 is smaller than the number of battery segments 41 already taken out from the vehicle to be taken out (hereinafter, the number of taken out segments), the center server 100 of the second embodiment requests the user of the vehicle to be taken out to provide the battery segments 41. When the number of battery segments 41 to be taken out as the carried segments during the loading of the vehicle to be taken out is set to the number of pre-take-out segments, the carried segments are the sum of the number of taken-out segments and the number of pre-take-out segments. The processing according to the second embodiment will be described mainly with respect to differences from the first embodiment.

When the planning unit 120 makes a manufacturing plan, if the number of extracted segments is smaller than the required number of segments, the requesting unit 140 generates request information requesting the supply of the battery segments 41. When the user of the vehicle 10 receives the request information via the communication device 50, the user of the vehicle 10 requests the user of the vehicle 10 to provide the battery segment 41 by causing a display input device, not shown, to display an image corresponding to the request information.

Promise a user based on a request for the request information operates, for example, the display input device and promise is based on the provision of the battery segment 41 of the request information. The input display device that received the operation provided by the user promise of the battery section 41 transmits the corresponding information corresponding to the operation to the center server 100 by the communication device 50. The center server 100 aggregates the pieces of the corresponding information transmitted from the plurality of users, and calculates the number of pieces of the extracted previous stage for each degradation degree.

Next, a specific process by the center server 100 will be described. Fig. 11 is a flowchart showing an example of processing executed by the center server 100. First, the obtaining unit 110 obtains the number of manufactured vehicles of each vehicle type inputted through an input device (not shown) (step S301). Next, the planning unit 120 reads the collected data 151, and obtains the number of mounted segments that can be supplied to the manufacture of the vehicle for each degradation degree of the battery segment 41 (step S303). Next, the planning unit 120 derives and obtains the number of segments required for manufacturing all vehicles from the number of manufacturing steps for each vehicle model (step S305).

Next, the planning unit 120 determines whether or not the number of extracted segments is equal to or greater than the number of segments required for manufacturing all the vehicles (step S307). This determination is made for each degradation degree of the battery segment 41. When it is determined that the number of extracted segments is equal to or greater than the number of segments required for manufacturing all vehicles, the planning unit 120 generates the planning data 152 in the same manner as in the first embodiment (step S309), and the output unit 130 causes the output device 180 to output the planning data 152 generated by the planning unit 120 (step S311). In this way, the center server 100 ends the processing shown in fig. 11.

When it is determined that the number of taken-out segments is not equal to or greater than the number of segments required for manufacturing all vehicles (less than the number of segments required for manufacturing all vehicles), the requesting unit 140 requests the plurality of users for the provision of the battery segments 41 with respect to the battery segments 41 having insufficient degradation degree (step S313).

The center server 100 waits for the corresponding information of the request of the battery segment 41, for example, for a certain period. The planning unit 120 calculates the number of segments before extraction based on promise information acquired during a certain period, and determines whether or not the sum of the number of extracted segments and the number of segments before extraction is equal to or greater than the number of segments required for manufacturing all vehicles (step S315). When it is determined that the sum of the number of taken out segments and the number of taken out preceding segments is equal to or greater than the number of segments required for manufacturing all the vehicles, the planning unit 120 adds the number of taken out preceding segments to each degradation degree (step S317), and the flow advances to step S309. When it is determined that the sum of the number of taken out sections and the number of taken out sections is not equal to or greater than the number of sections required for manufacturing all the vehicles, the planning unit 120 adds the number of manufactured products (new products) of the factory to each degree of degradation for the shortage (step S319), and the flow advances to step S309.

Then, the planning unit 120 generates the planning data 152 in the same manner as in the first embodiment (step S309), and the output unit 130 causes the output device to output the planning data 152 generated by the planning unit 120 (step S311). In this way, the center server 100 ends the processing shown in fig. 11.

According to the second embodiment described above, in the manufacturing plan of the vehicle, when the number of used battery segments to be mounted is insufficient, the provision of the battery segments is requested to the user of the vehicle that mounts the battery segments that can be used as the mounted battery segments. Therefore, when a plurality of vehicles are manufactured, the battery segment mounted on the vehicle can be easily made to be a battery segment suitable for the vehicle.

In the second embodiment, when it is determined in step S315 that the sum of the number of removed segments and the number of segments before removal is not equal to or greater than the number of segments required for manufacturing all vehicles, the number of manufacturing steps of the new factory product is added, but for example, the process in step S315 may be repeated until the sum of the number of removed segments and the number of segments before removal is equal to or greater than the number of segments required for manufacturing all vehicles. The target value may be set for the number of stages before taking out, and when the number of stages before taking out is equal to or greater than the target value, the number of production stages of the new factory product may be added.

While the embodiments for carrying out the present invention have been described above, the present invention is not limited to the embodiments, and various modifications and substitutions can be made without departing from the spirit of the present invention.
