Fig. 3 is a schematic diagram of a battery power shortage prevention control system according to an embodiment of the present invention, and as shown in fig. 3, a VCU (vehicle control unit) is an electric control system of an electric vehicle, and this system is a core component of the electric vehicle, and this component is equivalent to an ECU of a gasoline vehicle. The VCU can control the motor work of pure electric vehicles, can also control the operation of other electronic equipment on the pure electric vehicles, and the VCU is equivalent to the brain of pure electric vehicles. The BMS (battery management system) is arranged in the power battery and used for collecting battery temperature, voltage and current and supplying power under high voltage. DCDC (direct current to direct current) devices for conversion of direct current to direct current for conversion from high voltage to low voltage. The lead-acid battery (accumulator) supplies power to low-voltage components of the whole vehicle, such as VCUs, BMSs and the like.
After the vehicle is turned off and enters a static state, the VCU periodically wakes up (the time can be calibrated and can be 1 day or one week and the like), the voltage of the lead-acid storage battery is detected after waking up, and if the voltage is lower than a certain value (for example, 20V, the value can be calibrated), the lead-acid storage battery is considered to be about to enter a power-down state, and the vehicle can possibly not catch fire. At this time, the VCU wakes up the BMS and the DCDC, the BMS executes high-voltage operation, and after the high-voltage power-on is completed, the DCDC enters a working state, and at this time, the electric energy flows to the power battery → DCDC → lead-acid storage battery. At the moment, the lead-acid storage battery is in a power supplementing state. The power supply time is carried out for a period of time (1 hour or a plurality of hours, which can be calibrated). And after the power supply is completed, the VCU/BMS/DCDC enters a dormant state. At this time, the power supply action is completed until the VCU wakes up next time, and the above operations are repeated.
