Battery combustion tester

The Battery Combustion Tester is designed for safety evaluation of lithium-ion batteries by simulating direct exposure to flame jet combustion under extreme conditions.

The equipment verifies battery behavior when subjected to sustained flame impingement, including risks of ignition, explosion, rupture, or excessive temperature rise.

The system adopts liquefied petroleum gas (LPG) as fuel with a Bunsen burner configuration and integrates a reinforced explosion-proof test chamber, gas leakage protection, and automatic flame control, making it suitable for laboratory certification testing and safety compliance evaluation.
