Battery internal resistance test

The DC Resistance Tester is a multifunctional device and is mainly used for testing battery performance. It can accurately measure the DC internal resistance and open circuit voltage of batteries. By combining the upper-level machine, PLC and hardware integration, it has realized the intelligent automation of the testing process. The equipment can be connected with automated production lines for AGV cart loading and unloading, and significantly improve testing efficiency. Its unique modular structure design allows for easy replacement and maintenance of components. In the battery detecting cycle, it can conduct charge and discharge tests under multiple cutoff conditions, meeting the multiple  testing modes such as constant current with voltage limit and constant power, and other testing modes. Its powerful data monitoring function can display when executing the test and supports export in EXCEL format, which can provide in-depth analysis of battery performance. It is an important device in the Battery Testing System, and also can act as a Battery Sorting Machine, in which batteries can be accurately sorted based on the test data.
