In this embodiment, an intelligent power supply method for an electronic device operating on the vehicle is provided, fig. 1 is a flowchart of the intelligent power supply method according to one embodiment of the present invention, as shown in fig. 1, and the flowchart includes the following steps:
Step S101, acquiring state information of a target vehicle.
Fig. 2 is a schematic diagram of an electric vehicle power management system according to an embodiment of the invention. The electric vehicle power management system is located in a target vehicle and comprises a power battery (also called a high-voltage power battery), a direct current converter (Direct current to Direct, DCDC), a storage battery (also called a low-voltage storage battery), a vehicle-mounted charger, a direct current charging pile, a whole vehicle control unit (vehicle control unit, VCU), a low-voltage accessory system, a motor system, a high-voltage accessory system and the like. The low voltage accessory system includes a low voltage battery monitor, a Battery Management System (BMS) MANAGEMENT SYSTEM, a controller for a target vehicle using low voltage power, sensors, and low voltage loads. It is understood that the target vehicle includes a power battery, a dc converter, and a storage battery.
The direct-current charging pile can directly charge the high-voltage power battery, and the vehicle-mounted charger can charge the power battery through external charging equipment. The power battery can directly supply power for the motor system and the high-voltage accessory system, and can also supply power for the VCU, the low-voltage accessory system and the storage battery through the DCDC. DCDC is capable of converting the high voltage power of a power cell (e.g., 200V-500V) to low voltage power (e.g., 9V-16V) to power VCU, low voltage accessory systems, and batteries. The battery may power the VCU and low voltage accessory system when the DCDC is dormant (i.e., not awake or not operating) or after the power battery is powered down.
As shown in fig. 3, VCU, DCDC, BMS and the low-voltage battery power monitor constitute a control subsystem of the electric vehicle power management system. The low-voltage battery charge monitor can monitor the state of charge (SOC) of the battery in real time and transmit a related signal to the VCU. The BMS can monitor the state of charge and the fault state of the power battery in real time and transmit related signals to the VCU, and can control the relay inside the power battery, so that the power battery is powered on or powered off. The DCDC can transfer the opening and closing state of the DCDC to the VCU, can be opened or disconnected according to the command sent by the VCU, and can transfer the electric quantity of the power battery to the VCU, the low-voltage accessory system, the low-voltage storage battery and the like when the DCDC is opened, and the power battery cannot be the VCU, the low-voltage accessory system and the low-voltage storage battery after the DCDC is closed. The VCU can control the opening or closing of the DCDC and control the output voltage of the DCDC, the VCU can also control the power-on or power-off of the power battery by sending instructions to the BMS, and the DCDC can comprehensively coordinate the dormancy and the awakening of the controller of the whole vehicle network. When the controller is in the awakening state, the controller can normally work, can send or receive related signals and perform related operation, has higher power consumption, and when the controller is in the dormant state, the controller stops working and does not perform related operation, the power consumption is lower, and only dormant static current exists.
The state information is used for reflecting the starting state and the charging state of the target vehicle, wherein the starting state of the target vehicle comprises the starting state of the target vehicle and the non-starting state of the target vehicle, namely the vehicle is started, namely the vehicle is ignited, and the non-starting state of the vehicle is flameout. The state of charge of the target vehicle is the state of charge of the power battery in the target vehicle, which includes being in the state of charge, i.e., the power battery of the vehicle is being charged, and being in the non-state of charge, i.e., the power battery of the vehicle is not being charged.
It will be appreciated that from the state information of the target vehicle, it may be determined that there may be four states of the target vehicle, namely, an activated and non-charged state, an activated and charged state, a non-activated and charged state, and a non-activated and non-charged state, as shown in table 1 below.
TABLE 1
And step S102, controlling the direct current converter to be started according to the state information of the target vehicle so that the power battery charges the storage battery through the direct current converter.
By charging the battery, the battery can be prevented from being depleted due to the exhaustion of the electric power.
Through the steps, the state information of the target vehicle is obtained, and the direct current converter is controlled to be started according to the state information of the target vehicle, so that the power battery charges the storage battery through the direct current converter. Therefore, no matter what state the vehicle is in, the direct-current converter can be started to charge the storage battery, the storage battery is prevented from being deficient in power, and the energy consumption waste is avoided. Meanwhile, when the power consumption failure occurs to the vehicle, the information of the vehicle failure can be reported to the driver in time to prompt the driver to maintain, so that the influence on the subsequent use is avoided. The technical problems of poor battery consumption and poor driver experience of the electric vehicle in the related art are solved.
Optionally, in response to the target vehicle being in the activated and non-charged state, activated and charged state or non-activated and charged state, after step S102, the following steps are further performed:
step S103, adjusting the output voltage of the direct current converter according to the ambient temperature, the charge state of the storage battery and a preset table.
The preset table is used for recording output voltage values of the direct current converters corresponding to the charge states of the different storage batteries at different ambient temperatures.
Specifically, when the target vehicle is in a started and non-charged state, the VCU does not perform sleep control, so that the whole vehicle network is in an awake state. The VCU adjusts the output voltage of the DCDC according to the ambient temperature, the charge state of the storage battery and a preset table. The preset table is shown in table 2 below, wherein the ambient temperature T1 is preferably 0 ℃, here by way of example only, a non-unique value, and the voltage U1 is between 14V and 16V, preferably 14.5V, here by way of example only, a non-unique value.
TABLE 2
When the target vehicle is in a starting and charging state, the VCU does not carry out dormancy control, so that the whole vehicle network is in an awakening state. The VCU adjusts the output voltage of the DCDC according to the ambient temperature, the charge state of the storage battery and a preset table. The preset table is shown in table 3 below, wherein the ambient temperature T1 is preferably 0 ℃, here is only an example, a non-unique value, the voltage U2 is between 14.5V and 16V, preferably 15V, here is only an example, a non-unique value, and the voltage of U2 is greater than the voltage of U1, so that the target vehicle can be charged quickly.
TABLE 3 Table 3
When the target vehicle is in a non-starting and charging state, the VCU controls the BMS, the DCDC and the low-voltage storage battery power monitor to be in a wake-up state all the time, and controls other controllers of the low-voltage accessory system to sleep, so that power consumption is reduced. The VCU adjusts the output voltage of the DCDC according to the ambient temperature, the charge state of the storage battery and a preset table. The preset table is shown in table 3 above, wherein the ambient temperature T1 is preferably 0 ℃, here is only an example, a non-unique value, the voltage U2 is between 14.5V and 16V, preferably 15V, here is only an example, a non-unique value, and the voltage of U2 is greater than the voltage of U1, so that the target vehicle can be charged quickly.
Therefore, the output voltage of the direct-current converter can be adjusted in real time according to the preset table, the battery is prevented from being deficient, the service life of the battery is effectively guaranteed, the output voltage of the direct-current converter can be properly reduced when the electric quantity of the battery is high, the power of low-voltage accessories is reduced, the energy consumption of the whole vehicle is reduced, and the charging electric energy is saved.
Optionally, as shown in fig. 4, in response to the target vehicle being in a non-activated and non-charged state, before controlling the dc converter to be turned on, the following steps are further included:
Step S102a, controlling the whole vehicle network to sleep, and recording a first state of charge, a first ambient temperature and a first sleep time.
The first state of charge is the state of charge of the storage battery before the whole vehicle network sleeps, the first ambient temperature is the ambient temperature before the whole vehicle network sleeps, and the first sleep time is the time counted from the time when the whole vehicle network sleeps.
The VCU comprehensively coordinates the whole vehicle network to sleep, records the first state of charge SOC1 and the first ambient temperature Tx of the battery before the whole vehicle network sleeps, and starts timing from the time of the whole vehicle network sleeping to obtain a first sleep time t.
Step S102b, in response to the first ambient temperature being greater than the preset ambient temperature and the first sleep time exceeding the first preset time, or the first ambient temperature being less than or equal to the preset ambient temperature and the first sleep time exceeding the second preset time, waking up the battery management system, the DC converter and the battery power monitor.
The battery management system is used for monitoring the fault state of the power battery in real time and controlling the power battery to be electrified or electrified, and the storage battery electric quantity monitor is used for monitoring the charge state of the storage battery in real time.
Illustratively, when the first ambient temperature Tx > the preset ambient temperature T2 (T2 is preferably 0 ℃, here by way of example only, not the only value), and the first sleep time T > the first preset time T1 (T1 is preferably 3 hours, here by way of example only, not the only value), the VCU wakes up the BMS, DCDC and low voltage battery power monitor. When the ambient temperature Tx < the preset ambient temperature T2 and the first sleep time T > the second preset time T2 (T2 < T1 and T2 is preferably 2 hours, here by way of example only, non-unique value), the VCU wakes up the BMS, DCDC and low voltage battery monitors.
Optionally, after step S102b, the following steps are further performed:
and step S104, determining that the target vehicle has power consumption faults in response to the first state of charge meeting a first preset condition, recording fault codes and sending the fault codes to the instrument when the power battery is electrified so as to prompt a driver that the target vehicle has power consumption faults.
The first preset condition is that the difference value between the first charge state and the second charge state is larger than the first preset charge state SOC_cal1, and the second charge state SOCx is the current charge state of the storage battery monitored by the storage battery charge monitor in real time.
It can be understood that after the VCU wakes up the BMS, DCDC, and the low-voltage battery power monitor, the VCU determines according to the second state of charge SOCx of the battery that is monitored and reported by the low-voltage battery power monitor in real time. When SOC1-SOCx > soc_cali1 (soc_cali1 is preferably 5%, and is only an example, and is not a unique value), the VCU determines that the target vehicle has a power consumption failure when the power consumption of the battery of the target vehicle is considered to be large and there is a power consumption abnormality, records a failure code, and sends the failure information to the meter when the target vehicle is powered up next time, so as to prompt the driver that the target vehicle has a power consumption failure.
Step S105, controlling the power battery to be electrified.
It can be understood that the VCU sends an instruction to the BMS, controls the BMS to turn on a relay inside the power battery, high-voltage-powers the power battery to make the target vehicle in a charged state, and controls the DCDC to turn on so that the DCDC outputs a voltage to charge the power battery to the storage battery. Therefore, when the power consumption of the storage battery is high, the power battery is controlled to charge the storage battery, and the storage battery is prevented from being deficient.
Optionally, after step S102b, the following steps are further performed:
And step S106, controlling the power battery to be electrified in response to the first state of charge meeting the second preset condition.
The second preset condition is that the difference value between the first state of charge and the second state of charge is greater than the second preset state of charge soc_cal2 and less than or equal to the first preset state of charge, and the second state of charge is the current state of charge of the storage battery monitored by the storage battery electric quantity monitor in real time.
It can be understood that after the VCU wakes up the BMS, DCDC, and the low-voltage battery power monitor, the VCU determines according to the second state of charge SOCx of the battery that is monitored and reported by the low-voltage battery power monitor in real time. When SOC_cal2 < SOC1-SOCx is not more than SOC_cal1, it is considered that the battery power consumption of the target vehicle is large but no power consumption abnormality occurs. Therefore, the VCU sends an instruction to the BMS to control the BMS to turn on the relay inside the power battery, to power up the power battery at high voltage, to make the target vehicle in a charged state, and to control the DCDC to turn on so that the DCDC outputs voltage to charge the power battery for the storage battery. Therefore, when the power consumption of the storage battery is high, the power battery is controlled to charge the storage battery, and the storage battery is prevented from being deficient.
Optionally, after step S102b, the following steps are further performed:
And step S107, responding to the first state of charge to meet a third preset condition, controlling the whole vehicle network to sleep, and recording the new first state of charge, the new first environment temperature and the new first sleep time again.
The third preset condition is that the difference value between the first charge state and the second charge state is smaller than or equal to the second preset charge state, and the second charge state is the current charge state of the storage battery monitored by the storage battery electric quantity monitor in real time.
It can be understood that after the VCU wakes up the BMS, DCDC, and the low-voltage battery power monitor, the VCU determines according to the second state of charge SOCx of the battery that is monitored and reported by the low-voltage battery power monitor in real time. When SOC1-SOCx is smaller than or equal to SOC_cal2, the power consumption of the storage battery of the target vehicle is considered to be smaller, and no abnormal power consumption exists. Therefore, the VCU controls the whole vehicle network to sleep, and the new first state of charge, the new first ambient temperature and the new first sleep time are recorded again to monitor the power consumption of the target vehicle, so that when the power consumption of the target vehicle is large or abnormal, the storage battery can be charged timely, the storage battery is prevented from being deficient, and the problem of abnormal power consumption of the target vehicle can be timely prompted to the driver, so that the driver can repair the vehicle timely.
Optionally, after step S105 or S106, the following steps are further performed:
and step S108, responding to full charge of the storage battery, controlling the direct current converter to be closed, controlling the power battery to be powered down and controlling the whole vehicle network to sleep, and recording the new first state of charge, the new first ambient temperature and the new first sleep time again.
It can be understood that after the electric quantity of the storage battery is full, the VCU controls the DCDC to be turned off and sends an instruction to the BMS, controls the BMS to turn off the relay inside the power battery, powers down the power battery, and then the VCU comprehensively coordinates the whole vehicle network to sleep, re-records the new first state of charge, the new first ambient temperature and the new first sleep time, and repeats the steps of and after step S102a to monitor the power consumption of the target vehicle. Therefore, when the power consumption of the target vehicle is high or abnormal, the storage battery can be timely charged, the storage battery is prevented from being deficient, and the problem of abnormal power consumption of the target vehicle can be timely prompted to the driver, so that the driver can repair the target vehicle in time.
