Abstract: This paper focuses on improving the safety and reliability of the high-voltage system of pure electric vehicles during the power-on,operation,and power-off processes. Taking the vehicle domain controller 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 management based on the vehicle characteristics during driving,charging,24-hour monitoring,and DC/DC automatic power replenishment, and it has passed the verification of effectiveness on the hardware-in-the-loop test platform.
Key words: pure electric vehicle; high-voltage power on and off; control strategy; Simulink/Stateflow
