4 FAQs about [New energy battery main negative relay]

How to measure the insulation resistance of a power battery?

In current industrial measurement, the insulation resistance value between the positive and negative terminals of the power battery and the shell (ground) can be directly measured through the measurement procedure set by the integrated withstand voltage tester, which is safer and more reliable.

What is the voltage range of a Class B Battery?

Electrical Performance Testing GB 18384-2020 specifies the voltage range of Class B power batteries as 60–1500 V, but in practice, as the power source of pure electric vehicles, the voltage of power batteries is commonly above 300 V [ 17 ].

Is a power battery a high voltage?

The voltage of the power battery is a high voltage, although the voltage level of the power battery is not high in the voltage level of the power grid; therefore, many manufacturers for power battery voltage measurement often directly use a desktop digital voltmeter to measure.

What is a BMS in a power battery?

BMS function in a power battery. The BMS reads the sensor parameters integrated inside the power battery to monitor the core parameters inside the automotive power battery in real time, providing information on remaining power, battery status, current, etc.
