Introduction

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, the short-circuit device must meet the internal resistance range of ≤5mΩ, so as to obtain the maximum short-circuit current required by the test; in addition, in the circuit design of the short-circuit device It must also be able to withstand the impact of large currents, so we chose industrial-grade DC electromagnetic contactors, all-copper terminals and internal copper plates for diversion. The wide and thick copper plates can effectively improve the heat dissipation effect, make the high-current short-circuit device safer, and effectively reduce the test equipment The loss to ensure the accuracy of the test data.

The short circuit tester adopts PLC automatic control to simulate the external short circuit of the battery, and meets UL1642, UN38.3, IEC62133, GB/T18287, GB/T 31241-2014 and other standards. Record battery voltage, current and surface temperature changes. The short-circuit test machine must have a resistance of 80±20mΩ across the circuit (including circuit breakers, wires and connecting devices), and each circuit can withstand a short-circuit current with a peak value of 1000A. You can choose the short-circuit stop mode: 1. Short-circuit time; 2. Battery surface temperature.

Test standard requirements

After the battery is fully charged in accordance with the specified test method, place it in an environment of 55°C ± 5°C, and place it for another 30 minutes after the battery temperature reaches 55°C ± 5°C. Then connect the positive and negative terminals of the battery with wires, and ensure that all external resistances are 80mΩ±20mΩ. Monitor the battery temperature change during the test. When one of the following two situations occurs, the test is terminated.

a) The battery temperature drops to 20% lower than the peak value; b) The short-circuit time reaches 24h.

Test result: the battery should not fire or explode, and the maximum temperature should not exceed 150℃
