2) after the vehicle enters a flameout state, all electronic components on the vehicle enter a low-power-consumption sleep mode;
3) after entering a sleep state, the DCDC control board is awakened once every 24 hours;
4) when the voltage of the storage battery is detected for three times continuously by the DCDC control board after the step 3), the interval of each time is 10 seconds, if the voltage of the storage battery cannot be detected for two times, the current compensation process is quitted permanently, if the average value of the voltage of the storage battery is higher than a standard value, wherein the standard value is 21V for a 24V system, and the standard value is 10V for a 12V system, the DCDC enters a sleep state and times again;
5) the average value of the voltage of the storage battery is lower than a standard value, wherein the standard value of a 24V system is 21V, the standard value of a 12V system is 10V, the DCDC control board wakes up the vehicle-mounted terminal and the high-voltage control board through CAN messages, and the message content is power supply wake-up;
6) after the vehicle-mounted terminal and the high-voltage control board confirm that the power supply is awakened, the high-voltage control board detects the safety of the high-voltage system, wherein the safety content comprises the insulation resistance value of the high-voltage system, the adhesion state of a contactor, and the voltage and current state of a power battery pack;
7) after the safety of the high-voltage system is confirmed, the high-voltage control board closes the contactor and sends a high-voltage safety message, and the message is read by the DCDC control board and the vehicle-mounted terminal;
8) if the high-voltage system has an unqualified safety item or an undetectable item, the high-voltage control panel sends the state message, and the DCDC control panel, the vehicle-mounted terminal and the high-voltage control panel enter a sleep mode and exit power supplement permanently;
9) when 7) is finished, the DCDC starts to supplement power to the storage battery, and sends out voltage and current information of the storage battery through the CAN bus;
10) when 9) is finished, the vehicle-mounted terminal sends the VIN code and the relevant information of the power supply process to the remote monitoring platform;
11) the remote monitoring platform issues vehicle information and power supply process related information to the vehicle user APP and the company after-sale APP, and related personnel can know the power supply state of the vehicle in time;
