After the battery pack is completed ,  Battery Comprehensive Tester is used to find the quality of battery based on different tests like Charging Test, Discharging Test, Over Charging Current Test, Over Discharging Current Test, Open Circuit Voltage of Battery Terminal 1 and 2, Short Circuit Test, AC IR test, DC IR test. We set the parameters in the software and the tester shows if the battery is Pass/Fail on the tested paramters. The tests usually takes only a few seconds (7-8 seconds)

1. Equipment introduction

The comprehensive test equipment for finished battery is a fast and accurate test equipment for the performance of finished battery. The main test items include: open circuit voltage, AC internal resistance, discharge test, discharge over-current test, short-circuit protection test, charging test and charging protection test. The system uses 32-bit ARM processor and 16 bit AD converter for voltage and current. Compared with the similar equipment, the system has the advantages of fast test speed, high test precision and support for multiple devices to operate at the same time. It is widely used in automobile electronics, aerospace, ship, solar energy storage, electric bicycle, electric motorcycle, backup power battery, communication power supply, etc.
