The electric vehicle power management system is positioned in a target vehicle and comprises a power battery (named a high-voltage power battery), a Direct current to Direct (DCDC) converter, a storage battery (named a low-voltage storage battery), a vehicle-mounted charger, a Direct current charging pile, a 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 charge monitor, a Battery Management System (BMS), and a controller, sensors, and low voltage loads, etc. using low voltage electricity in the target vehicle. 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 the 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. The DCDC can convert the high voltage (e.g., 200V-500V) of the power battery to a low voltage (e.g., 9V-16V) to power the VCU, low voltage accessory systems, and battery. The battery may power the VCU and low voltage accessory systems when the DCDC is dormant (i.e., not awake or operational) or after the power cell is powered down.
As shown in fig. 3, the VCU, DCDC, BMS, and low-voltage battery charge monitor form the control subsystem of the electric vehicle power management system. The low-voltage battery electric quantity monitor can monitor the state of charge (SOC) of the battery in real time and transmit related signals to the VCU. The BMS can monitor the state of charge and the fault state of the power battery in real time, transmits related signals to the VCU, and can control a relay inside the power battery so as to control the power battery to be powered on or powered off. DCDC can transmit the on-off state of self to VCU, can also open or break off according to the instruction that VCU sent, and when DCDC opened, can transmit power battery's electric quantity to VCU, low pressure annex system and low-voltage battery etc. after DCDC closed, power battery can't be VCU, low-voltage annex system and low-voltage battery. The VCU can control the on or off 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 commands to the BMS, and the DCDC can comprehensively coordinate the sleep and wake-up of the controller of the entire vehicle network. When the controller is in the wake-up state, the controller can normally work, can send or receive related signals and perform related operations, and has high power consumption.

When the target vehicle is in a non-start and charging state, the VCU controls the BMS, the DCDC and the low-voltage battery charge monitor to be in a wake-up state all the time, and controls other controllers of the low-voltage accessory system to be in a sleep state, thereby reducing the power consumption. And 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 by way of example only, a non-unique value, the voltage U2 is between 14.5V and 16V, preferably 15V, here by way of example only, 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.

and S102a, controlling the whole vehicle network to sleep, and recording a first charge state, a first environment temperature and first sleep time.
The first charge state is the charge state of a storage battery before the whole vehicle network is dormant, the first environment temperature is the environment temperature before the whole vehicle network is dormant, and the first dormancy time is the time counted from the time when the whole vehicle network is dormant.
Illustratively, the VCU comprehensively coordinates the whole vehicle network to sleep, records a first state of charge (SOC 1) and a first ambient temperature (Tx) of the storage battery before the whole vehicle network sleeps, and starts to time when the whole vehicle network sleeps 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 level 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 powered on or powered off, and the storage battery electric quantity monitor is used for monitoring the charge state of the storage battery in real time.
Illustratively, the VCU wakes up the BMS, the DCDC and the low voltage battery charge monitor when the first ambient temperature Tx > a preset ambient temperature T2(T2 is preferably 0 ℃, here by way of example only, a non-exclusive value) and the first sleep time T > a first preset time T1(T1 is preferably 3 hours, here by way of example only, a non-exclusive value). The VCU wakes up the BMS, the DCDC and the low voltage battery charge 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 are preferably 2 hours, by way of example only and not by way of limitation).
Optionally, after step S102b, the method further includes the following steps:
and step S104, responding to the first charge state meeting a first preset condition, determining that the target vehicle has power consumption faults, recording fault codes and sending the fault codes to an instrument when the power battery is electrified so as to prompt a driver that the target vehicle has the power consumption faults.
The first preset condition is that the difference value between the first state of charge and the second state of charge is larger than a first preset state of charge SOC _ cal1, and the second state of charge SOCx 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, the DCDC and the low-voltage battery charge monitor, the VCU makes a judgment according to the second state of charge SOCx of the battery monitored and reported in real time by the low-voltage battery charge monitor. When the SOC1-SOCx > SOC _ cal1(SOC _ cal1 is preferably 5%, by way of example only, and not a unique value), the VCU determines that the target vehicle has a power consumption fault, records a fault code, and sends the fault information to a meter when the target vehicle is powered on next time, so as to prompt the driver that the target vehicle has the power consumption fault, considering that the power consumption of the storage battery of the target vehicle is large and that the power consumption is abnormal.
And step S105, controlling the power battery to be electrified.
It can be understood that the VCU sends a command to the BMS to control the BMS to turn on a relay inside the power battery, to power up the power battery at a high voltage to put the target vehicle in a charged state, and the VCU controls the DCDC to turn on so that the DCDC outputs a voltage to charge the power battery for the secondary battery. Therefore, when the power consumption of the storage battery is large, the storage battery is charged by controlling the power battery, and the power shortage of the storage battery is prevented.
Optionally, after step S102b, the method further includes the following steps:
and S106, controlling the power battery to be electrified in response to the first charge state meeting a 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 a 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, the DCDC and the low-voltage battery charge monitor, the VCU makes a judgment according to the second state of charge SOCx of the battery monitored and reported in real time by the low-voltage battery charge monitor. When SOC _ cal2 < SOC1-SOCx ≦ SOC _ cal1, it is considered that the battery power consumption amount of the target vehicle is large but there is no power consumption abnormality. Therefore, the VCU sends a command to the BMS to control the BMS to turn on a relay inside the power battery, to power up the power battery at a high voltage to put the target vehicle in a charged state, and the VCU controls the DCDC to turn on so that the DCDC outputs a voltage to charge the power battery for the storage battery. Therefore, when the power consumption of the storage battery is large, the storage battery is charged by controlling the power battery, and the power shortage of the storage battery is prevented.
Optionally, after step S102b, the method further includes the following steps:
and S107, responding to the third preset condition that the first charge state meets the third preset condition, controlling the whole vehicle network to sleep, and recording a new first charge state, a new first environment temperature and 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, the DCDC and the low-voltage battery charge monitor, the VCU makes a judgment according to the second state of charge SOCx of the battery monitored and reported in real time by the low-voltage battery charge monitor. When SOC1-SOCx is less than or equal to SOC _ cal2, the battery consumption of the target vehicle is considered to be small and no abnormal power consumption is caused. Therefore, the VCU controls the whole vehicle network to sleep, records the new first charge state, the new first environment temperature and the new first sleep time again, and monitors the power consumption of the target vehicle, so that when the target vehicle has large power consumption or abnormal power consumption, the storage battery can be charged in time, the storage battery is prevented from being insufficient, the problem of abnormal power consumption of the target vehicle can be prompted to a driver in time, and the driver can repair the vehicle in time.
Optionally, after step S105 or S106, the following steps are further included:
and S108, responding to the full charge of the storage battery, controlling the direct current converter to be closed, controlling the power battery to be powered off, controlling the whole vehicle network to sleep, and recording a new first charge state, a new first environment temperature and new first sleep time again.
It can be understood that after the battery is fully charged, the VCU controls the DCDC to be turned off, and sends a command to the BMS to control the BMS to turn off a relay inside the power battery, power 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 step S102a and the following steps to monitor the power consumption of the target vehicle. Therefore, when the target vehicle has large power consumption or abnormal power consumption, the storage battery can be charged in time, the storage battery is prevented from being lack of power, the problem that the target vehicle has abnormal power consumption can be prompted to a driver in time, and the driver can repair the target vehicle in time.
