Scope of application
The battery short-circuit testing machine is mainly suitable for battery manufacturers, battery manufacturers, new energy vehicle Ovens, research institutes, colleges and universities, etc., which is used to simulate batteries for forced internal short-circuit testing under certain ambient temperature conditions or for extrusion testing under certain temperature conditions.
Experimental purpose
The device is designed based on a variety of 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 must also be able to withstand the impact of large current, so we choose industrial grade DC electromagnetic contactor and all copper terminals and internal copper plate diversion, wide and thick copper plate effectively improve the heat dissipation effect, make the high-current short-circuit device safer, effectively reduce the loss of test equipment, and ensure the accuracy of test data.
