The comfort level of electric vehicles is much higher than fuel-powered vehicles. Additionally, electric vehicles have lower energy consumption and emit zero harmful gases during operation, almost resulting in zero pollution. Therefore, electric vehicles have a broader development prospect. The power battery system, which serves as the important energy source for electric vehicles, plays a crucial role in the safety of the vehicle itself. During the charging process, excessive charging current can cause significant impact on relays and rectifier devices. Therefore, a reasonable and effective pre-charging circuit is essential for the safe charging process of the vehicle. By incorporating a pre-charge resistor and forming a pre-charge loop in the battery management system of electric vehicles, the voltage stress on components in the control system can be greatly reduced, the impact current in the circuit can be lowered, so the damage to relays can be prevented, ensuring the safe use of the power battery. The pre-charging system has significant practical value in ensuring the safe operation of electric vehicles.
