Battery Temperature Controlled Type External Short Circuit Tester

It is conforms to IEC62133 clause 7.3.2 ,8.3.1,8.3.2 IEC60086-4 clause 6.5.1 IEC60086-4 clause 6.5.8 6.5.9 ,IEC 60086-1 ,IEC61951,IEC61960, UN38.3 ,UL1642, UL2054, QC 743/744, MT/T 1051-2007,GB/T 2900.11-1988,GB31241-2014and etc.

It is designed according to multi type battery short circuit standard requirements,in the standard requirement,the short circuit device must conform to the range of internal resistance ≤5mΩ, 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 have chosen industrial grade DC electromagnetic contactors and all-copper terminals and internal copper plate diversion, thick copper plate to effectively improve the cooling effect, so that a large current short circuit device is safer, effectively reducing the loss of test equipment and ensuring the accuracy of test data.

It is consist of high current contactor,remote controller, voltmeter, ammeter etc.
