High Current Battery Short Circuit Testing Machine KS-10000A
Product Description
Appearance reference drawing (specifically, the actual object shall prevail)
1. Use high conductivity copper as a large current carrier during short circuit, and use a high-strength vacuum switch for short circuit (non-vacuum box);
2. Short circuit trigger (high-intensity vacuum switch opens and closes to perform short circuit) to achieve perfect short circuit test.
3. Resistance production: Use manual sliding measurement for 1-9 mΩ, superimpose 10-90 mΩ, and adjust freely by clicking on the computer or touch screen;
4. Resistor selection: nickel-chromium alloy, which has the advantages of good heat resistance, small coefficient of change at high temperatures, cheap price, high hardness and large overcurrent. Compared with constantan, it has disadvantages due to high hardness, easy bending and high humidity environment (80 % or more) oxidation rate is faster;
5. Using a shunt to directly divide the voltage for collection, compared with Hall collection (0.2%), the accuracy is higher, because Hall collection uses the inductance generated by the inductor coil to calculate the current, and the capture accuracy is not enough when an instant occurs.
