摘要
Abstract
A kind of performance testing system for electric vehicles (EVs) power battery, which adopts 89 C 52series microprocessor as the system's control center, is presented. Electronic inversion technique, constant cur-rent charging circuit was made up of IGBT and constant discharging circuit made up of paralleling-connected VMOS transistor are applied to save energy、 reduce dimension and lower power consumption. The system,which gathers the functions of battery voltage sampling, data processing, charging and discharging control, data and curve printing, keyboard & displaying together, can fulfill the whole testing process without an upper su- pervising computer. The testing process can not only be controlled automatically, but can be controlled manuallyalso. The testing results show that the system is steady, applicable and has an obvious energy-saving effect. The maximum charging and discharging current of the system is 500 A, which can meet the needs of testing the charging and discharging performance of both cell EVs power battery and EVs power battery pack. Therefore,the system solves the problem of testing EVs power battery.关键词
