Abstract：At present, the calibration of power battery charge & discharge test system is mainly done manually channel by channel in the shutdown state. It takes a long time, reducing the production efficiency, and has potential safety risks for operators. By means of non-contact measurement, an on-line calibration device is developed for multichannel high-accuracy voltage and current measurement under working condition of charge and discharge test system.
