Laboratory Battery Internal Short Circuit Tester For Lithium Battery

Introduction

This product is designed in accordance with the latest battery test standards such as Japanese Industrial Standards JISC 8714:2007, IEC62133-2013, and 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 exhaust function (That is, test exhaust gas is discharged after the test is completed). The control system 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.
