Project Description

Lithium ion battery cell short circuit tester

Battery and Cell Test Equipment China Manufacturer

Lithium-ion Battery Cell Short Circuit Tester is used to simulate an external short circuit at a specified temperature in the test chamber to evaluate the security performance.

Cells and batteries meet this requirement if their external temperature doesn’t exceed 170℃ and there is no disassembly, no rupture and no fire during the test and within 6 hours after the test (based on UN38.3).

This battery and cell test equipment own a precision temperature controller. Its design is based on multiple battery test standards for external short circuits with a total external resistance of 80mΩ ± 20mΩ or 5mΩ or specified. Industrially pneumatic suction contactor and pure-copper auxiliary units are adopted to ensure that they can withstand the short-circuit current as high as 1000 A, offer more security for users, and improve test data accuracy.

Lithium-ion battery cell short circuit tester is integrated with a PLC and touch screen controller for temperature control, short circuit test control, battery surface temperature, voltage, and current data acquisition.

The box structure is consists of an external short circuit device, viewing window, air exhaust port, pressure relief port, cable holes, etc.
