This paper focuses on improving the safety and reliability of the high-voltage system of pure elec-tric vehicles during the power-on,operation,and power-off processes.Taking the vehicle domain control-ler as the core,a control strategy of step-by-step high-voltage power on and off is designed based on the Simulink/Stateflow environment.This strategy implements precise high-voltage power on and off manage-ment based on the vehicle characteristics during driving,charging,24-hour monitoring,and DC/DC auto-matic power replenishment,and it has passed the verification of effectiveness on the hardware-in-the-loop test platform.
