Battery short-circuit tester

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 soil 20m, 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 contactors and all copper terminals and internal copper

plates to guide the flow, wide and thick copper plates 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 the test data.

Meet the standard
