The short circuit test chamber is used to test whether the lithium ion battery will explode and catch fire under the condition of a certain resistance short connection, and show the maximum current of the short connection through the relevant instrument. The short circuit test chamber integrated a variety of battery short circuit test standard requirement. According to the requirements of standard short circuit device must conform to the scope of internal resistance ≤5mΩ thus to get the large short-circuit current test requirements.
In addition, in the circuit design of the short circuit devices are also required to withstand the impact of high current, so we choose the industrial-grade dc electromagnetic contactor and copper wiring terminal and internal copper diversion, generous copper effectively increase the cooling effect, make large current short circuit device safer, effectively reduce the wastage of the testing equipment, to ensure the accuracy of the test data.
This battery external short circuit test is dangerous. Please use a separate testing room and open an observation window in the testing room to record the voltage and current data when the battery is short-circuited.

Class 3C battery safety testing equipment-temperature-controlled battery short-circuit test chamber introduction:
The temperature-controlled battery short-circuit test chamber is designed to comply with standards. According to the short circuit test requirements, the short circuit must be less than 5 mΩ to reach the maximum current.
Class 3C battery safety testing equipment-temperature controlled battery short circuit test chamber application
1. The design of battery high-current short-circuit machine complies with standards;
2. According to the short circuit test requirements, the short circuit must be less than 5mΩ to reach the maximum current;
3. The carrying capacity must be designed in the electrical system to prevent system short circuit; therefore, the Bell team chose industrial DC magnetic contacts with all-copper terminals and internal copper current conduction, and installed an internal active magnetic bead axial flow fan for cooling to ensure The test system is safer, the power consumption of the test machine is reduced, and the test data is inaccurate.
4. Test judgment criteria: No flame or explosion test after battery short circuit.
1. The contact resistance is low and the response speed is fast
2. Remote control, strong anti-interference ability and long life
3. The contactor action is reliable, safe, long life, and easy to maintain.
4. Safety and explosion-proof function
5. Button control interface, easy to operate
