Battery Test Chambers
Explosion-Proof Environmental Chambers for Lithium-Ion Battery and Module Testing
Lithium-ion battery testing carries a risk that most environmental testing doesn't: the test article itself can fail catastrophically. Overcharge, internal short, or a malfunction during temperature or humidity cycling can trigger thermal runaway — a self-sustaining, rapidly escalating heat release that standard chambers, built for benign test articles, aren't designed to contain. As battery pack capacities have grown, the consequences of testing that failure mode in unsuitable equipment have grown with them.
Sonacme's battery test chambers are explosion-proof environments for evaluating lithium-ion battery and battery module quality, durability, and performance under environmental stress — low or high temperature, rapid temperature change, and, with the humidity option, combined temperature/humidity cycling.
The chambers are available with or without humidity, selected according to the test profile the programme is qualifying against. The inner chamber is 1.2mm SUS304 stainless steel. Standard safety equipment includes an explosion-proof chain, status indicator, safety door lock, independent over-temperature protector and emergency stop; options include an explosion-proof pressure relief port, water sprinkler, CO2 fire extinguishing device, electronic combination lock, explosion-proof mesh for the observation window, H2/CO gas monitoring, GN2 purge, fireproof coating and video monitoring.
Standards commonly used for lithium-ion cells and modules include UL 1642, UL 2054, IEC 62133, IEC 62660-2, SAE J2464 and UN/DOT 38.3.
