Temperature Control Battery Short Circuit Tester

Tests to evaluate the electrical performance or safety of lithium-ion batteries and other secondary batteries include continuous charging tests, external short circuit tests, overcharging tests, over-discharging tests, and large-current tests. External short circuit tests simulate incorrect battery usage. These tests consist of short circuiting a battery from outside to simulate use that may cause fire or rupture. The battery's positive and negative terminals are connected to an external resistor, and the battery is observed to check for fire or rupturing. 
GRANDE can carry out external short circuit tests with high currents of up to 24 kA (a world-first), and in low- to high-temperature environments. 
Along with these short circuit tests, we also provide a comprehensive range of testing/certification services for compliance with UNECE Regulation R100, and provide safety testing, test consulting and certification services for vehicle battery packs/modules and energy storage devices.

8,Circuit resistance measurement function

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