[0002] New energy vehicles refer to all other energy vehicles except gasoline and diesel engines, including fuel cell vehicles, hybrid vehicles, hydrogen-powered vehicles and solar vehicles, etc., which have relatively low exhaust emissions; most of the new energy vehicles currently on the market are hybrid vehicles and pure electric vehicles. New energy vehicles refer to vehicles that use unconventional automotive fuels as a power source. New energy vehicles need to have their batteries tested before they are sold.

[0003] Existing battery testing devices can only test the performance of batteries in different environments, but cannot perform collision tests on the safety of batteries. Battery protective shells are very important for battery performance and safety in use, and can prevent batteries from being damaged due to collisions. Therefore, a battery testing device is needed that can perform collision tests on battery protective shells, and then determine the impact strength that the battery protective shells can withstand.
