Product Overview
Purpose of the experiment
The equipment is designed according to various battery short circuit test standards，According to the standard, the short circuit device must meet the requirements of internal resistance range ≤ 5m Ω (or 20m Ω)，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.Therefore, we chose industrial grade DC electromagnetic contactor, all copper terminal and inner copper plate,The wide and thick copper plate can effectively improve the heat dissipation effect，Make the high current short circuit device safer，Effectively reduce the loss of test equipment，Ensure the accuracy of test data。
