The temperature-controlled battery short-circuit testing machine is designed according to the requirements of various battery short-circuit test standards. According to the standard requirements, the short-circuit device must meet the internal

The resistance range is less than or equal to 5mΩ, so as to obtain the maximum short-circuit current required by the test; in addition, the circuit design of the short-circuit device must also be able to withstand the impact of large currents, so we chose industrial-grade DC electromagnetic contactors and all-copper terminals and internal copper plate conductors. The current, wide and thick copper plate effectively improves the heat dissipation effect, makes the high-current short-circuit device safer, effectively reduces the loss of the test equipment, and ensures the accuracy of the test data.
