STD Battery short-circuit tester

The Battery Short-Circuit Tester is designed for external short-circuit safety testing of lithium-ion batteries and battery packs.

The system simulates external short-circuit conditions under both room temperature and elevated temperature environments, while simultaneously detecting, recording, and monitoring battery surface temperature during the test.

The equipment consists of a short-circuit control unit and a temperature-controlled explosion-proof oven. It meets the safety testing requirements of multiple international and national standards and is widely used for certification testing, quality control, and battery safety evaluation.
