The battery forced internal short circuit test machine simulates the forced internal short circuit test of the battery under certain ambient temperature conditions. The test box is made of stainless steel, with good temperature uniformity, and has a ventilation function (that is, exhaust gas after the test is completed). The control system of the testing machine is a PLC touch screen menu operation, and the data collection frequency can reach 100 times per second. At the same time, the test pressure, pressure holding time, measured pressure, battery voltage, battery temperature, pressure drop speed, etc. are set through PLC programming.
