Battery impact tester

The Battery Impact Tester is designed for safety performance evaluation of lithium-ion cells and battery packs by simulating heavy object impact conditions.

The tester reproduces extreme mechanical abuse by allowing a specified mass to fall freely from a defined height and strike the battery sample through a metal bar, thereby assessing battery resistance to impact and the risk of fire, explosion, or leakage.

The system is equipped with a reinforced explosion-proof test chamber, motorized lifting mechanism, and automatic control system, making it suitable for laboratory certification testing and production safety verification.
