Project Description

Battery Forced Internal Short Circuit Testing machine

Lithium Battery Cell Forced Internal Short Circuit Tester China Supplier

Lithium Battery Forced Internal Short Circuit Tester is a battery testing equipment designed according to IEC 62133 and the standards of Japan, France, South Korea and Switzerland to perform Forced internal short circuit tests on cylindrical cells and prismatic cells.

Amade forced internal short circuit tester comprises a temperature control chamber, pressing jig, and professional testing software with data acquisition and analysis functions.

The control system is operated via the testing software. The frequency of voltage acquisition is up to 100 Hz. In addition, the test pressure, pressure retention time, and the cell voltage drop can be set and monitored in real time via the software.

Cell Forced Internal Short Circuit Testing Machine Features

  • It has an extensive temperature control range from 0 to 100℃, and the temperature uniformity is as good as ± 2℃.
  • The reliable refrigeration unit adopts TECUMSEH full-closed compressor, environmentally friendly refrigerant, and adopts refrigeration accessories and temperature controllers of world-renowned brands.
  • The pressing system is divided into pressing jigs and control software with a data acquisition and statistics functions.
  • This chamber is configured with professional pressing test software compatible with the Windows operating system, having PID closed-loop control, strong anti-interference ability, high data acquisition accuracy, and good repeatability.
  • Voltage acquisition frequency is as high as 100Hz. The system can monitor the pressure, displacement, the voltage changes in real time.
  • The crush force sensor adopts American Transcell, whose accuracy is ± 0.5% F.S.
  • The crush system adopts a Panasonic servo motor and driver and high-precision ball screw, making the speed control more stable and precise.
  • A professional pressing jig is made of Nitrile rubber or acrylic resin.
  • Designed with a test hole for the cell’s cables going through the shell of the test chamber when conducting the charge and discharge tests.
  • The test chamber is mounted with an air exhaust fan because cells crush test may produce a lot of smoke.
