What are the testing items for battery testing of new energy vehicles?

As follows:

1, safety performance:

Overcharging, overdischarge, short circuit, squeezing, acupuncture, heavy object impact, falling, heat abuse, low pressure, seawater immersion, washing, external fire.

2. Electrical performance:

Capacity, rate discharge, internal resistance, cycle life, accelerated aging, SOC calibration, storage performance, charge retention capacity, energy efficiency.

3, environmental performance:

Temperature cycling, temperature shock, constant damp heat, mechanical vibration, mechanical shock, insulation test.

New energy vehicles in a broad sense, also known as alternative fuel vehicles, include pure electric vehicles, fuel cell electric vehicles and other vehicles that all use non-petroleum fuels, as well as hybrid vehicles, ethanol gasoline vehicles and other vehicles that use some non-petroleum fuels.

All existing new energy vehicles are included in this concept and can be divided into six categories: hybrid vehicles, pure electric vehicles, fuel cell vehicles, alcohol ether fuel vehicles, natural gas vehicles and so on.
