Machine introduce:
The temperature controlled battery short circuit testing machine is designed based on various battery short circuit testing standards. According to the standards, the short circuit device must meet the internal resistance range of<5m Ω to obtain the maximum short circuit current required for the test; In addition, the circuit design of the short-circuit device must also be able to withstand the impact of high currents. Therefore, we have selected industrial grade DC electromagnetic contactors, all copper wiring terminals, and internal copper plates for flow guidance. The wide and thick copper plates effectively improve the heat dissipation effect, make the high current short-circuit device safer, effectively reduce the loss of test equipment, and ensure the accuracy of test data.
Instrument features:
1. Surface treatment of the body: DuPont powder from the United States, electrostatic spray painting process, cured at high temperature of 200 ℃ to ensure long-lasting color fastness;
2. The box is reinforced with anti riot design structure, ensuring safety and reliability;
3. Visual bulletproof function window, tempered glass, built-in perspective observation LED light;
4. Intelligent PID temperature control system, accurate temperature control, and stable performance;
5. The interlayer is made of high-temperature resistant insulation cotton, with good insulation performance;
6. Adopting a fully enclosed box structure, the short-circuit working environment is completely isolated from the instrument circuit;
7. Short circuit work is equipped with smoke alarm sound and light alarm function to alarm and judge the occurrence of explosions;
8. The bottom of the entire test box is equipped with 4 universal wheels and fixed foot cups, making it easy to move;
