Abstract: The power battery safety problem brought about by the rapid growth of electric vehicles has become the focus of the industry. The rapid safety inspection of power batteries has become the demand of the current market. This paper designs a power battery charge and discharge detection system based on bidirectional inverter hardware module and C#.NET host computer software module. The system is tested for electric vehicle power batteries and second use batteries, which are characterized by rapid detection and in-depth inspection. The rapid performance shows that the battery pack insulation safety and monomer consistency are detected within two minutes, and it obtains the distribution map of opening circuit voltage (OCV) of battery cells and direct current (DC) internal resistance to quickly diagnose the battery consistency problem according to the DC internal resistance detection module. The data of each detection module finally generates an electronic test report and is saved in Excel format for further analysis as well. The system is reliable and can provide a reference for the promotion and application in the field of energy storage.

Key words: electric vehicle power battery, power battery charge and discharge detection system, C#.NET, rapid detection
