This equipment is designed based on the requirements of various battery short-circuit test standards. According to the standard requirements, the short-circuit device must meet the internal resistance range of 80±20mΩ (or ≤10mΩ), so as to obtain the maximum short-circuit current required by the test; in addition, the circuit design of the short-circuit device also It must be able to withstand the impact of large current, so we choose industrial-grade DC electromagnetic contactor and all-copper terminal and internal copper plate for diversion. The thick copper plate can effectively improve the heat dissipation effect, make the high-current short-circuit device safer, and effectively reduce the test equipment loss to ensure the accuracy of the test data.
