New Energy Vehicle Special Safety Analyzer

1、Basic Knowledge of New Energy Vehicle Testing

Potential Equalization Test: Potential equalization is achieved by physically connecting the exposed conductive parts of electrical equipment to a reference point or equipotential point on the vehicle body (usually the chassis) to minimize the potential difference between them. This connection ensures that, in the electrical system, especially in high-voltage systems, the conductive parts maintain the same potential, thereby reducing the risk of electric shock and other safety hazards.

Insulation Resistance Test: The electrification level of new energy vehicles is higher than that of traditional cars. Under harsh operating conditions (car vibrations, external environmental humidity and temperature), or in the event of a collision or rollover, the insulation performance between the high-voltage circuit and the vehicle chassis may be reduced, leading to vehicle fires and endangering the safety of drivers and passengers. The higher working voltage of new energy vehicles places higher demands on the insulation performance between the high-voltage electrical system and the vehicle chassis.

Whole vehicle insulation test: The high-voltage components of electric vehicles are a parallel structure, and the insulation resistance of the entire system is the parallel value of all high-voltage component insulation resistances. According to GB-T 18384-2015 Electric Vehicle Safety Requirements, the minimum insulation resistance requirement: DC 100Ω/V, AC 500Ω/V.

Insulation Monitoring Verification: In high-voltage electrical systems of electric vehicles, if insulation failure occurs, it will pose serious safety hazards. To ensure that the vehicle can promptly send an alarm signal to the driver in case of insulation failure, the vehicle should have an insulation resistance monitoring function.
