Battery Environmental Test Chamber
Combined environmental testing solutions for testing batteries
Lithium batteries are increasingly used in electric vehicles, motorcycles, smartphones, and other applications, driving higher demands for safety, reliability, and performance testing. We offer reliable test solutions that cover everything from single-condition testing to complex simulations combining temperature, humidity, impact, vibration, low pressure, and salt spray environments. All our environmental test systems are designed to comply with China’s national standard GB 38031-2020, which defines safety requirements for traction batteries used in electric vehicles.
Given the wide range of battery sizes, cells, modules, packs, and full systems, we provide an extensive lineup of chambers, including high-temperature ovens, temperature and humidity chambers, rapid thermal cycling units, walk-in rooms, altitude chambers, and salt spray testers. A broad selection of standard accessories and optional components ensures each setup can be adapted to your specific protocols.
When batteries are stressed during tests, overcharging or other failures may occur, potentially causing damage. As energy density increases, so do the risks. To mitigate these hazards, GWS integrates multiple safety protections designed to safeguard facilities and personnel.
