New energy vehicles are the main direction of transformation, upgrading and green development of the global vehicle industry and are strategic choices for high-quality development of the Chinese vehicle industry. With the intelligent and networking high-speed development of new energy vehicles, a large number of high and new technologies are widely applied to vehicles, such as wireless charging, remote starting and control, auxiliary automatic driving, big data detection and monitoring, power battery management and the like, and the static current of the new energy vehicles during power-off parking is increased, so that the problem of low-voltage storage battery feeding is easy to occur when the vehicles are parked for a long time.
At present, the electricity is mainly supplemented in the following two ways: firstly, during the parking period of the vehicle under the power supply, the voltage value of the storage battery is monitored through the storage battery sensor, when the voltage of the storage battery is lower than a certain value, the whole vehicle is awakened to supplement the power of the storage battery, and after the power supplement is completed, the vehicle is in the power supply dormant state, so that the power supplement effect is good, the power feed risk is low, but the storage battery sensor needs to be additionally arranged, the cost of the whole vehicle is increased, and the power supplement cannot be performed on the vehicle without the storage battery sensor; secondly, the vehicle is automatically started at fixed intervals to supplement power for the low-voltage storage battery, however, the fixed time intervals are difficult to adapt to different actual conditions, if the set time intervals are short, the vehicle needs to be frequently started, excessive power supplement can occur, unnecessary electric quantity waste is caused, and if the set time intervals are long, a large feeding risk still exists.
Therefore, the application provides a vehicle storage battery power supplementing method, a vehicle, a storage medium and a system, the determination of the first current voltage value of the storage battery when the vehicle is powered off is realized by acquiring the first current voltage value of the storage battery when the high-voltage power supply of the vehicle is detected to be disconnected, the dynamic adjustment of the target wake-up time is realized by determining the target wake-up time corresponding to the first current voltage value, the power supplementing requirement is generated when the target wake-up time is reached in timing, the high-voltage power supply of the vehicle is controlled to be communicated based on the power supplementing requirement, the power supplementing is carried out on the storage battery, and the flexible adjustment of the power supplementing time is realized. The voltage value of the storage battery is closely related to the remaining capacity, that is, the current voltage value of the storage battery can represent the remaining capacity of the storage battery, that is, the first current voltage value is different, the remaining capacity of the storage battery is different, and further, the time for which the storage battery can be used for powering off and parking the vehicle is different. Therefore, the target wake-up time determined by the first current voltage value can be adapted to different residual capacities of the storage battery, and the dynamic adjustment of the target wake-up time is realized. Compare in the mode that a period of fixed time at every interval starts the vehicle and mends the electricity, this application is when the high voltage power supply who detects the vehicle disconnection, the target wake-up time confirmed through first current voltage value more adapts to current actual conditions, under the higher condition of residual capacity, can confirm longer target wake-up time, it frequently carries out invalid start to reduce the vehicle, avoid the vehicle to mend the electricity when battery residual capacity is higher, it is extravagant to reduce the electric quantity that excessive benefit electricity caused, the whole standby time of extension vehicle, under the lower condition of residual capacity, this application can in time know through first current voltage value, and confirm corresponding shorter target wake-up time, greatly reduced the feed risk. That is, the vehicle storage battery power supplementing method provided by the application does not need to increase the cost of the whole vehicle, and can flexibly adapt to different actual conditions, so that the technical problem that the feeding risk of a low-voltage storage battery in the prior art is large is solved, the invalid starting times of the vehicle can be reduced, and the resources are saved.
The embodiment of the application provides a vehicle storage battery power supplementing method, and in an embodiment of the vehicle storage battery power supplementing method, referring to fig. 1, the vehicle storage battery power supplementing method is applied to a vehicle storage battery power supplementing system, and includes the following steps:
step S10, when the disconnection of a high-voltage power supply of a vehicle is detected, acquiring a first current voltage value of a storage battery;
in the present embodiment, it should be noted that the battery in the present embodiment refers to a low-voltage battery on a vehicle. In addition to a power battery for supplying power to a high-voltage electrical system, a low-voltage battery is also generally disposed on a new energy vehicle, where the high-voltage battery is mainly used to drive a vehicle motor, and for example, when starting, driving and accelerating, a large voltage of the power battery is required to implement and supply power to a high-power subsystem, and the low-voltage battery is mainly used to supply power to a low-voltage electrical system on the vehicle, when a high-voltage power supply of the vehicle is turned on, a high-voltage DC/DC (Direct-Current-to-Direct-Current converter) will automatically start to provide a voltage of a whole vehicle power grid, and after the vehicle is started, the high-voltage power supply of the vehicle automatically runs, and after the high-voltage power supply of the vehicle is turned off, the low-voltage battery provides a quiescent Current required for a vehicle to sleep, and components required to provide the quiescent Current on the vehicle include: an electronic control unit, vehicle theft prevention related parts (e.g., sensors and recorders, etc.), a remote controller (e.g., BCM (body control module), TBOX, etc.), and the like, which are required in order to maintain the data memorizing function.
The Vehicle storage Battery power supplementing method is applied to a Vehicle storage Battery power supplementing System, and the Vehicle storage Battery power supplementing System can comprise a TBOX (Telematics-BOX), a VCU (Vehicle control unit), a BMS (Battery Management System), a DC/DC (direct Current/direct Current), a storage Battery and the like. In an implementable manner, referring to fig. 2, the vehicle storage battery power supply system comprises a TBOX, a VCU, a BMS, a DC/DC and a storage battery, the TBOX wakes up to generate a power supply demand, wakes up the VCU and sends the power supply demand to the VCU, the VCU sends a work instruction to the DC/DC and sends a high voltage instruction to the BMS after receiving the power supply demand, the BMS provides high voltage to the DC/DC based on the received high voltage instruction, the DC/DC supplies power to the storage battery, after the power supply is completed, the VCU controls the high voltage power supply to be disconnected and sends a power supply completion signal to the TBOX, and the TBOX can determine the high voltage power supply of the vehicle to be disconnected according to the power supply completion signal, so as to enter the next power supply process.
For convenience of explanation, the subsequent embodiments are explained in a case where the vehicle battery charging system includes TBOX and VCU, where TBOX is used to acquire a first present voltage value of the battery when disconnection of the high-voltage power supply of the vehicle is detected; determining a target wake-up time corresponding to the first current voltage value; and generating a power supplementing demand when the timing reaches the target wake-up time. And the VCU is used for controlling the high-voltage power supply of the vehicle to be communicated based on the electricity supplementing requirement and supplementing electricity to the storage battery. This particular implementation of the embodiments, however, does not represent a limitation on the vehicle battery recharging method of the present application, i.e., the TBOX or VCU may perform the vehicle battery recharging method alone or in combination with other devices.
Specifically, during the power-on operation of the vehicle, the connection state of the high-voltage power supply of the vehicle can be monitored, and when the high-voltage power supply of the vehicle is detected to be switched to the disconnection state, the TBOX can continue to be powered by the low-voltage storage battery to operate, and the current first current voltage value of the storage battery is detected.
Step S20, determining a target wake-up time corresponding to the first current voltage value;
in this embodiment, specifically, a corresponding relationship between a voltage value and a wake-up time is preset in the TBOX, and when the first current voltage value is detected, a target wake-up time corresponding to the first current voltage value is determined according to a preset corresponding relationship between the voltage value and the wake-up time, where the corresponding relationship between the voltage value and the wake-up time may be a mapping relationship table, or may also be a functional relationship, an algorithm, or the like, and in the corresponding relationship between the voltage value and the wake-up time, the voltage value and the wake-up time are positively correlated, that is, the larger the voltage value is, the longer the target wake-up time is, and specifically, the target wake-up time may be determined according to an actual situation, an actual test result, or the like.
Optionally, the step of determining the target wake-up time corresponding to the first current voltage value includes:
step S21, determining a first target voltage range to which the first current voltage value belongs;
step S22, determining a target wake-up time corresponding to the first target voltage range according to a first mapping relation table of a preset voltage range and the wake-up time.
In this embodiment, specifically, the TBOX preset a plurality of voltage ranges, matches a corresponding wake-up time for each voltage range, determines a first mapping table of the voltage ranges and the wake-up time, compares the first current voltage value with each voltage range when the first current voltage value is detected, determines a first target voltage range to which the first current voltage value belongs from each voltage range, and further queries the first mapping table of the voltage ranges and the wake-up time according to the first target voltage range to determine a target wake-up time corresponding to the first target voltage range.
In one practical implementation, the correspondence between the voltage range and the SOC and the wake-up time is shown in table 1:
TABLE 1
SOC[%] U00[V] Wakeup time
100%(≥12.9V) ≥12.925V 17 days
90%≤SOC<100% 12.81≤U00<12.925 15 days
80%≤SOC<90% 12.69≤U00<12.81 12 days
70%≤SOC<80% 12.57≤U00<12.69 8 days
60%≤SOC<70% 12.445≤U00<12.57 4 days
50%≤SOC<60% 12.315≤U00<12.445 2h
40%≤SOC<50% 12.185≤U00<12.315 2h
30%≤SOC<40% 12.055≤U00<12.185 2h
20%≤SOC<30% 11.92≤U00<12.055 2h
10%≤SOC<20% 11.78≤U00<11.92 2h
0%≤SOC<10% 11.61≤U00<11.78 2h
In table 1, SOC refers to the SOC range of the battery, and U00 refers to the voltage range of the battery, and as can be seen from table 1, the voltage ranges correspond to the SOC ranges one to one, and to the wake-up times one to one. For example, if it is detected that the first current voltage value is 12.72V, the first current voltage value belongs to a voltage range of 12.69 ≦ U00 < 12.81, that is, the first target voltage range determined at this time is 12.69 ≦ U00 < 12.81, which indicates that the SOC of the battery at this time is greater than or equal to 80% and less than 90%, and the target wake-up time determined at this time is 12 days; if the first current voltage value is detected to be 12.11V, the first current voltage value belongs to a voltage range of U00 & lt 12.445, namely the first target voltage range determined at the moment is U00 & lt 12.445, which indicates that the SOC of the storage battery is smaller than 60% at the moment, and the target wake-up time is determined to be 2h at the moment.
Step S30, generating a power supplementing requirement when the timing reaches the target wake-up time;
in this embodiment, specifically, after determining the target wake-up time, TBOX starts timing and enters a sleep state, and when the timing reaches the target wake-up time, TBOX ends sleep, generates a power supplement demand, wakes up the VCU, and sends the power supplement demand to the VCU.
Optionally, the step of generating a power supplementing requirement when the time reaches the target wake-up time includes:
step S31, when the timing reaches the target wake-up time, acquiring a second current voltage value of the storage battery;
in this embodiment, specifically, after determining a target wake-up time, the TBOX starts timing, and enters a sleep state, when the timing reaches the target wake-up time, the TBOX finishes sleeping, detects a current second current voltage value of the storage battery, and determines whether the second current voltage value is smaller than a preset first voltage limit value, where the preset first voltage limit value is a voltage limit value suitable for power supplement, and the voltage value smaller than the preset first voltage limit value indicates that no excessive power supplement is currently performed, and the power supplement time and resource consumption are reasonable, the power supplement benefit is high, and the voltage value larger than the preset first voltage limit value indicates that power supplement is currently not required, and specifically, it may be determined according to an actual situation and an actual test result, and in a normal situation, when the voltage value is larger than the preset first voltage limit value, the remaining electric quantity of the storage battery is not completely consumed within the wake-up time at least, and the risk of power feed is small, so that power supplement can be performed after the wake-up time.
Optionally, after the step of obtaining the second current voltage value of the battery, the method further includes:
step A10, if the second current voltage value is determined to be smaller than a preset first voltage limit value, judging whether the second current voltage value is smaller than a preset second voltage limit value;
in this embodiment, specifically, if it is determined that the second current voltage value is smaller than the preset first voltage limit, the TBOX is suitable for power supplement at this time, but if the second current voltage value is too low, the power supplement time may be too long or the power consumption may be high, and the overall benefit of power supplement is reduced, so that it is detected whether the second current voltage value is smaller than the preset second voltage limit, where the preset second voltage limit is a voltage limit that needs power supplement, and the voltage value smaller than the preset second voltage limit indicates that power supplement is currently needed, and if power supplement is not currently performed, there may be a risk of power feeding.
And step A20, if yes, reducing and adjusting the wake-up time in the first mapping relation table according to the difference value between the second current voltage value and the preset second voltage limit value, so as to update the wake-up time in the first mapping relation table.
In this embodiment, specifically, if it is determined that the second current voltage value is smaller than a preset second voltage limit value, the TBOX indicates that power needs to be supplemented currently, if power is not supplemented currently, there may be a risk of power feeding, so a difference value between the second current voltage value and the preset second voltage limit value is calculated, a target time difference value is determined according to the difference value between the second current voltage value and the preset second voltage limit value, and a corresponding relationship between a preset voltage difference value and a time difference value, where a first corresponding relationship between the voltage difference value and the time difference value may be a mapping relationship table, or may be a functional relationship, an algorithm, and the like, in a first corresponding relationship between the voltage difference value and a wake-up time, the voltage difference value is positively correlated with the time difference value, that is the difference value between the second current voltage value and the preset second voltage limit value, and the time difference value is larger, specifically, that the mapping relationship is determined according to an actual situation, an actual test result that the wake-up time difference value in the first current voltage value is greater, that the wake-up time difference value is greater, that the first current voltage value is smaller than the wake-up time difference value, and the wake-up time difference is determined, that is smaller than 0, and that the new wake-up time difference value is determined, and that is directly decreased, and the wake-up time difference value is smaller than the wake-up time difference value, and the wake-up time difference value is determined, and the wake-up time difference value is smaller than the new wake-up time difference value, and the wake-up time difference value is determined.
In an implementation manner, the step of performing reduction adjustment on the wake-up time in the first mapping relation table according to the difference between the second current voltage value and the preset second voltage limit value includes: and determining the number of voltage ranges which are separated between the voltage range to which the second current voltage value belongs and the maximum voltage range which is greater than or equal to the preset second voltage limit value according to the difference between the second current voltage value and the preset second voltage limit value, determining that the time difference value is 1 time unit if the number of the separated voltage ranges is less than 1, determining that the time difference value is the sum of the product of the number of the separated voltage ranges multiplied by 3 time units and 1 time unit if the number of the separated voltage ranges is greater than or equal to 1, and reducing the wake-up time in the first mapping relation table by the time difference value to obtain new wake-up time, wherein the time unit can be 2 days, 1 day, 12h and the like. For example, as shown in table 1, if 12.315 is determined as the second voltage limit, the time unit is determined as 1 day, and the detected second current voltage value is 12.21, the difference between the second current voltage value and the preset second voltage limit is 0.105, it can be determined that the voltage range to which the second current voltage value belongs is adjacent to the maximum voltage range which is greater than or equal to 12.315, and 0 voltage range is provided between the two, and therefore the time difference is determined as 1 day, the total wake-up time in table 1 is reduced by 1 day, the wake-up time corresponding to the voltage range whose voltage is less than 12.445 is reduced by less than 0, and the wake-up time corresponding to the voltage range whose voltage is less than 12.445 is determined as 0; if 12.315 is determined as the second voltage limit, the time unit is determined as 1 day, and a second current voltage value is detected to be 12.01, the difference between the second current voltage value and the preset second voltage limit is 0.305, that is, it can be determined that 2 voltage ranges are separated between the voltage range to which the second current voltage value belongs and the maximum voltage range smaller than 12.315, so that it is determined that the time difference is 1+2 × 3=7 days, the total wake-up time in table 1 is reduced by 7 days, the wake-up time corresponding to the voltage range with the voltage smaller than 12.57 is reduced by less than 0, and the wake-up time corresponding to the voltage range with the voltage smaller than 12.57 is determined to be 0.
Step S32, if the second current voltage value is determined to be smaller than a preset first voltage limit value, generating a power supplementing requirement;
in this embodiment, specifically, if it is determined that the second current voltage value is smaller than the preset first voltage limit value, the TBOX indicates that power supplement is suitable at this time, so the VCU is awakened, and a power supplement requirement is sent to the VCU.
Step S33, if the second current voltage value is determined to be greater than or equal to a preset first voltage limit value, determining re-awakening time according to the difference value between the second current voltage value and the preset first voltage limit value;
in this embodiment, specifically, if it is determined that the second current voltage value is greater than or equal to a preset first voltage limit value, the TBOX indicates that power supplement may not be required at this time, so that it is not necessary to wake up the VCU, calculate a difference between the second current voltage value and the preset first voltage limit value, and determine a re-wake-up time according to the difference between the second current voltage value and the preset first voltage limit value and a corresponding relationship between a preset voltage difference value and a wake-up time, where the corresponding relationship between the voltage difference value and the wake-up time may be a mapping relationship table, or may be a functional relationship, an algorithm, or the like, and in the corresponding relationship between the voltage difference value and the wake-up time, the voltage value and the wake-up time are positively correlated, that is, the larger the difference between the second current voltage value and the preset first voltage limit value is, the longer the re-wake-up time is, which may specifically be determined according to an actual situation, an actual test result, or the like.
In an implementation manner, the step of determining the re-wake-up time according to the difference between the second current voltage value and the preset first voltage limit includes: and determining the number of voltage ranges which are separated between the voltage range to which the second current voltage value belongs and the minimum voltage range corresponding to the preset first voltage limit value according to the difference between the second current voltage value and the preset first voltage limit value, if the number of the separated voltage ranges is less than 1, determining that the re-awakening time is 1 time unit, and if the number of the separated voltage ranges is greater than or equal to 1, determining that the re-awakening time is the sum of the product of the number of the separated voltage ranges multiplied by 3 time units and 1 time unit, wherein the time units can be 2 days, 1 day, 12h and the like. For example, as shown in table 1, if 12.445 is determined as the first voltage limit, the time unit is determined as 1 day, and a second current voltage value is 12.455, if the difference between the second current voltage value and the preset first voltage limit is 0.01, it can be determined that the voltage range to which the second current voltage value belongs is adjacent to the minimum voltage range smaller than 12.445, and 0 voltage range is provided between the two, so that the re-wake-up time is determined as 1 day; if 12.445 is determined as the first voltage limit, the time unit is determined as 1 day, and a second current voltage value is detected to be 12.72, the difference between the second current voltage value and the preset first voltage limit is 0.275, that is, it can be determined that the voltage range to which the second current voltage value belongs and the minimum voltage range smaller than 12.445 are separated by 2 voltage ranges, so that the re-wake-up time is determined to be 1+2 × 3=7 days.
Step S34, adding the awakening time in the first mapping relation table to the re-awakening time to update the awakening time in the first mapping relation table;
in this embodiment, specifically, the TBOX updates the wake-up time in the first mapping table, and adds the re-wake-up time to each wake-up time originally written in the first mapping table to obtain a new wake-up time, so that when the next time the high-voltage power supply of the vehicle is detected to be disconnected, and the first mapping table is queried according to the voltage value of the storage battery, the updated new wake-up time is queried, and the queried new wake-up time is determined as the target wake-up time to wake up the TBOX. When the target awakening time is deviated from the actual situation every time, adaptive adjustment is immediately carried out, the accuracy of the next set target awakening time is improved, the frequency of awakening again in the next awakening process is reduced, and unnecessary energy consumption caused by frequent awakening of TBOX is reduced.
And step S35, when the timing reaches the re-awakening time, returning to the step of acquiring the second current voltage value of the storage battery.
In this embodiment, specifically, the TBOX starts timing and enters a sleep state, and when the timing reaches the re-wake-up time, the TBOX ends sleep, returns to the step of acquiring the second current voltage value of the storage battery, re-detects the current second current voltage value of the storage battery, and circulates in this way until it is determined that the second current voltage value is smaller than the preset first voltage limit value, and sends a power supplement demand to the VCU.
In this embodiment, the battery may decay with the increase of the service time, and the discharging condition may change accordingly, besides, the environmental temperature and the like may also affect the discharging condition of the battery, so that the speed of the power consumption of the battery may become faster or slower, if the speed of the power consumption of the battery becomes faster, the total power consumption may increase within the same wake-up time, and thus the feeding risk may occur, for example, after the vehicle is parked under high voltage for 10 days, the power consumption of the battery may only decrease to 50%, but if the vehicle is parked under very low temperature, the feeding risk may occur after the vehicle is parked for 10 days. The method has the advantages that the awakening time can be dynamically adjusted when the change occurs every time, so that the awakening time for next power supplement is more reasonable, the residual power after the awakening is in a more reasonable range, the situation of excessive power supplement due to too high residual power is avoided, and the feeding risk due to too low residual power is avoided.
And S40, controlling the high-voltage power supply of the vehicle to be communicated based on the power supplementing requirement, and supplementing power to the storage battery.
In this embodiment, specifically, after receiving a power supplement demand, the VCU controls the connection of the high-voltage power supply based on the power supplement demand, and supplements power to the storage battery at a high voltage on the entire vehicle.
In this embodiment, when the high-voltage power supply of the vehicle is detected to be disconnected, the first current voltage value of the storage battery is acquired, the first current voltage value of the storage battery is determined when the vehicle is powered off, the target wake-up time corresponding to the first current voltage value is determined, dynamic adjustment of the target wake-up time is achieved, the power supplementing requirement is generated when the target wake-up time is reached in timing, the high-voltage power supply of the vehicle is controlled to be connected based on the power supplementing requirement, the storage battery is supplemented, and flexible adjustment of the power supplementing time is achieved. The voltage value of the storage battery is closely related to the remaining power, that is, the current voltage value of the storage battery can represent the remaining power of the storage battery, that is, the first current voltage value is different, the remaining power of the storage battery is different, and further, the time for the storage battery to power off and park the vehicle is different, so that the target wake-up time determined by the first current voltage value can be adapted to the different remaining power of the storage battery, and the dynamic adjustment of the target wake-up time is realized. Compare in the mode that a period of fixed time at every interval starts the vehicle and mends the electricity, when the high voltage power supply who detects the vehicle breaks off, the target wake-up time of confirming through first current voltage value more adapts to current actual conditions, under the lower condition of residual capacity, this application can in time know through first current voltage value to confirm the target wake-up time that corresponds, greatly reduced the feed risk, overcome the great technical problem of the feed risk of prior art low pressure battery.
Further, referring to fig. 3, based on the above-mentioned embodiment of the present application, in another embodiment of the present application, the same or similar contents to the above-mentioned embodiment may be referred to the above description, and are not repeated herein. On the basis, the step of controlling the high-voltage power supply of the vehicle to be communicated based on the electricity supplementing requirement comprises the following steps of:
step S41, determining a third current voltage value of the storage battery based on the power supplementing requirement;
in this embodiment, specifically, after receiving the power supplement demand, the VCU may obtain the third current voltage value of the storage battery from the power supplement demand, and may also detect the current third current voltage value of the storage battery.
Before the TBOX sends the power supplementing requirement, the voltage value of the storage battery can be detected firstly, and the detection result and the power supplementing requirement are sent to the VCU together, so that when the VCU receives the power supplementing requirement with voltage value information, the voltage value detected by the TBOX can be directly used as a third current voltage value, and repeated detection is not needed.
Step S42, determining a target power supplementing duration corresponding to the third current voltage value;
in this embodiment, specifically, a corresponding relationship between a voltage value and a power supplement duration is preset in the VCU, and when a third current voltage value is determined, a target power supplement duration corresponding to the third current voltage value is determined according to a corresponding relationship between a preset voltage value and the power supplement duration, where the corresponding relationship between the voltage value and the power supplement duration may be a mapping relationship table, or a functional relationship, an algorithm, or the like, and in the corresponding relationship between the voltage value and the power supplement duration, the voltage value is negatively correlated with the power supplement duration, that is, the larger the voltage value is, the shorter the power supplement duration is, and specifically, the determination may be performed according to an actual situation, an actual test result, or the like.
Optionally, the step of determining the target power supplementing duration corresponding to the third current voltage value includes:
step S421, determining a second target voltage range to which the third current voltage value belongs;
step S422, determining a target power compensation duration corresponding to the second target voltage range according to a second mapping relationship table of a preset voltage range and the power compensation duration.
In this embodiment, specifically, a plurality of voltage ranges are preset in the VCU, a corresponding power supplement duration is matched for each voltage range, a second mapping relationship table of the voltage ranges and the power supplement duration is determined, when the third current voltage value is determined, the third current voltage value is compared with each voltage range, a second target voltage range to which the third current voltage value belongs is determined from each voltage range, and then the second mapping relationship table of the voltage ranges and the power supplement duration is queried according to the second target voltage range to determine a target power supplement duration corresponding to the second target voltage range.
In an implementable manner, the correspondence between the voltage range and the SOC and the power-on duration is as shown in table 2:
TABLE 2
SOC[%] U00[V] Duration of electricity compensation
100% 12.925 0
90%≤SOC<100% 12.81≤U00<12.925 0
80%≤SOC<90% 12.69≤U00<12.81 0
70%≤SOC<80% 12.57≤U00<12.69 0
60%≤SOC<70% 12.445≤U00<12.57 0
50%≤SOC<60% 12.315≤U00<12.445 3h
40%≤SOC<50% 12.185≤U00<12.315 4h
30%≤SOC<40% 12.055≤U00<12.185 5h
20%≤SOC<30% 11.92≤U00<12.055 6h
10%≤SOC<20% 11.78≤U00<11.92 7h
0%≤SOC<10% 11.61≤U00<11.78 7.5h
In table 2, SOC refers to the SOC range of the battery, and U00 refers to the voltage range of the battery, and as can be seen from table 2, the voltage ranges correspond to the SOC ranges one to one, and correspond to the power supplement time periods one to one. For example, if it is detected that the second current voltage value is 12.315V, the second current voltage value belongs to a voltage range of 12.315 ≤ U00 < 12.445, that is, the second target voltage range determined at this time is 12.315 ≤ U00 < 12.445, which indicates that the SOC of the battery at this time is greater than or equal to 50% and less than 60%, and the power supplement time period determined at this time is 3h; if the second current voltage value is 12.485V, the second current voltage value belongs to a voltage range of 12.445 being equal to or less than U00 and less than 12.57, namely the second target voltage range is 12.445 being equal to or less than U00 and less than 12.57, the SOC of the storage battery is greater than or equal to 60% and less than 70% at the moment, the determined power supplementing time period is 0h, and power supplementing is not needed.
Step S43, supplementing power to the storage battery and starting timing;
in this embodiment, specifically, the VCU controls the connection of the high-voltage power supply, supplies power to the battery when the high voltage is applied to the entire vehicle, and starts timing.
And step S44, stopping the power supply to the storage battery when the timing reaches the power supply duration.
In this embodiment, specifically, when the time reaches the electricity compensation time, the VCU stops compensating the electricity for the storage battery.
Optionally, the step of stopping supplying power to the storage battery further includes:
step S45, acquiring a fourth current voltage value of the storage battery;
in this embodiment, specifically, after the time for the VCU to replenish the power of the storage battery reaches the power replenishing duration, after the VCU stops replenishing the power of the storage battery, before the high voltage power supply is disconnected and the whole vehicle runs into the high voltage power supply, the VCU first detects a current fourth current voltage value of the storage battery, and determines whether the fourth current voltage value is greater than or equal to a preset third voltage limit value, where the preset third voltage limit may be set to a higher voltage value range, for example, a voltage value range corresponding to an SOC of 90% to 100%, so as to replenish the power of the storage battery to a higher electric quantity without excessive replenishment.
Step S46, if the fourth current voltage value is determined to be smaller than a preset third voltage limit value, power supplementing is carried out on the storage battery, timing is started, power supplementing duration corresponding to the second target voltage range in the second mapping relation table is added to the preset power supplementing duration again, and therefore the power supplementing duration in the second mapping relation table is updated;
in this embodiment, specifically, if it is determined that the fourth current voltage value is smaller than the preset third voltage limit, it indicates that the power compensation efficiency at this time is lower than the estimated power compensation efficiency, and power compensation may be continued, so that the VCU controls the connection of the high-voltage power supply, supplies power to the storage battery at a high voltage on the vehicle, starts timing, and updates the power compensation duration in the second mapping relation table, adds the power compensation duration corresponding to the second target voltage range in the second mapping relation table to the preset power compensation duration to obtain a new power compensation duration corresponding to the second target voltage range, and when power compensation is required next time when the voltage of the storage battery is in the second target voltage range, power compensation is not required again, i.e., the storage battery may be charged to a higher electric quantity range higher than the preset third voltage limit at a time, where the preset power compensation duration may be determined according to a time required to charge the storage battery from the preset third voltage limit to full charge, so that the remaining electric quantity of the storage battery may be increased again after power compensation, but an actual power compensation result may not be determined according to an actual test result of 0.h, and an actual test result of h may be 0.e., h.
Step S47, when the timing reaches the electricity recharging duration, stopping recharging the storage battery, and returning to the step of acquiring the fourth current voltage value of the storage battery;
in this embodiment, specifically, when the time reaches the electricity compensation time, the VCU stops compensating electricity for the storage battery, and returns to the step of obtaining the fourth current voltage value of the storage battery, and the electricity compensation effect is evaluated again.
Step S48, if it is determined that the fourth current voltage value is greater than or equal to a preset fourth voltage limit, decreasing and adjusting the power supply duration corresponding to the second target voltage range in the second mapping relationship table to update the power supply duration in the second mapping relationship table, where the preset fourth voltage limit is greater than the preset third voltage limit.
In this embodiment, specifically, if it is determined that the fourth current voltage value is greater than or equal to the preset third voltage limit, the VCU indicates that the current power supply supplies power to the storage battery in an expected higher electric quantity range, so that it may be determined that the current power supply is completed, the high-voltage power supply is turned off, the high-voltage power supply under the entire vehicle is also turned off, before the high-voltage power supply under the entire vehicle is turned off, it is determined whether the fourth current voltage value is greater than or equal to the preset fourth voltage limit, where the preset fourth voltage limit is greater than the preset third voltage limit, the fourth voltage limit is a voltage limit for excessive power supply, and may be a voltage value when the SOC of the storage battery is 100%, and if it is determined that the fourth current voltage value is greater than or equal to the preset fourth voltage limit, it indicates that the current power supply may be excessive power supply, that is, that the power supply efficiency at this time is increased as compared with the estimated power supply efficiency, so that the power supply duration corresponding to the second target voltage range in the second mapping relation table may be reduced by a time that the preset voltage limit is still reduced from the preset third voltage limit, and the time may be reduced by the preset voltage limit, so that the actual power supply duration may be reduced from the preset voltage limit may be reduced by 0.5, and the actual time may be determined, and the time may be reduced, for example, and the time may be determined according to the third voltage limit.
In this embodiment, the target power supplementing time duration is dynamically determined by the VCU based on the third current voltage value detected after wake-up, although the voltage value during wake-up can be controlled in a relatively stable and appropriate range through dynamic adjustment of wake-up time, certain fluctuation still exists, compared with the fixed power supplementing time duration, the method for detecting the voltage value after wake-up and before power supplement is simple, and the residual electric quantity after power supplement is completed can be controlled in a stable higher voltage value range more accurately, so that the standby time of a vehicle can be prolonged, and the risk of power feeding after high-voltage electric parking under the vehicle can be reduced by controlling the residual electric quantity after power supplement in a higher current range.
