Battery large current short-circuit machine is designed to comply with the standard;
According to the short-circuit test requirement, the short-circuit must be less than 5 mO to achieve maximum current;
Load-bearing capacity must be designed in the electrical system for short-circuit system; Thus, the Bell’s team selects industrial DC magnetic contact with the full copper terminal and internal copper current conduction, and internal active bead axial fan is mounted to cool to ensure the test system safer and reduce the test machine power consumption and enable the test data inaccuracy.
Test judgment standards: no flame or explosion after battery short-circuit test.
