【Abstract】 In this paper, a kind of performance testing system for electric bicycle power battery is introduced. Consisting of two－ level computers, the system is mainly used to test the battery’ s capacity, cycle－ life and the charging and discharging voltage curve. The system, which is designed specially for electric bicycle power battery has the functions of constant current charging,constant voltage charging,asynchronous starting and stopping for different channels, and testing the cells and battery packs simultaneously. It can also simulate the practical running situations of electric bicycle power battery. Practical operating proves that the system is steady,precise and applicable, it well meets the needs of electric bicycle power battery plants and research institute, and has a broad application prospects.更多还原
