Battery Impact Test Chamber
The Battery Impact Test Chamber is a specialized safety testing enclosure designed to perform standardized battery impact tests under controlled and protected conditions. It is used in combination with a falling weight mechanism to simulate mechanical abuse by dropping a defined mass onto a battery sample through a steel rod.
During testing, the battery is placed on a flat surface, with a 15.8 ± 0.2 mm steel rod positioned across the center. A 9.1 kg or 10 kg weight is released from a specified height (commonly 610 mm or up to 1000 mm) to evaluate the battery’s resistance to impact. The chamber provides a reinforced, explosion-protected environment, ensuring safe observation and containment in case of thermal events.
This equipment is suitable for compliance testing, R&D validation, and battery safety assessment in laboratory environments.

Test Principle
(1) Place the battery sample on a flat impact platform
(2) Position a 15.8 mm diameter steel rod across the sample center
(3) Raise a specified weight (9.1 kg or 10 kg) to a defined height
(4) Release the weight for free-fall vertical impact
(5) Observe battery response such as deformation, leakage, fire, or explosion
(6) Each sample is subjected to a single impact event as required by standards
Note: According to test requirements, compliant batteries should not exhibit fire or explosion after impact.
