Scope of application:
Battery Crush & Nail Penetration Test Chamber is suitable for simulating the squeezing and acupuncture of various batteries during use, transportation, storage or disposal of household waste.
The battery short circuit testing machine is mainly suitable for battery manufacturers, battery users, new energy vehicle manufacturers, scientific research institutes, colleges and universities, etc. It is used to simulate the forced internal short circuit test of the battery under certain ambient temperature conditions or under certain temperature conditions. Perform extrusion test below.
Purpose:
This equipment is designed based on the requirements of various battery short-circuit test standards. According to the standard requirements, the short-circuit device must meet the internal resistance range of 80±20mΩ (or <10mΩ), 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 It must be able to withstand the impact of large currents, so we chose industrial-grade DC electromagnetic contactors, all-copper terminals and internal copper plate conductors. The wide and thick copper plates effectively improve the heat dissipation effect, make high-current short-circuit devices safer, and effectively reduce the cost of test equipment. loss to ensure the accuracy of test data.
Experimental conditions:
1. Ambient temperature: 25±5ºC;
2. Relative humidity: 45-85%RH;
3. Atmospheric pressure: 86~106KPa;
4. No direct sunlight or direct radiation from other heat sources;
5. There is no strong vibration around;
