锂离子电池组充放电过程中对电压、电流和温度比较敏感,而且各单体电池存在不一致性.提出了一种新的锂电池组充放电智能管理系统,能够实时检测电池组单体的电压、电流和温度,控制电池组均衡充放电,并实现对电池组充放电过流保护和负载短路过流保护.系统具有集成度高,体积小,精度高,反应快并能够灵活地扩展系统容量等优点.%In the lithium-ion battery charging and discharging process, the voltage, current and temperature was quite sensitive. Also, for each cells, its behavior was different. A kind of new intelligent management system for lithium-ion battery pack was proposed, which could check the real-time voltage, current and temperature of each cell, control the balanced charging and discharging of battery, and realize the over-current protection and discharging, and short circuit current protection in the process of charging. The system has the advantages of high integration, small volume, high precision, quick response, and easy scale-up of the capacity.
