摘　　要：电动汽车电池管理系统(BMS)需对电池进行管理并控制充电器的充电电流与终止电压。当给不同的蓄电池充电时,充电器须可编程以满足不同的充电需求。与多数研究不同,研究的充电器采用改变反馈比的方式改变目标值,硬件上采用数模混合控制。上层控制系统BMS控制采样系统中数字电位器的大小改变反馈比,下层模拟芯片完成控制算法以减少BMS计算开销。最后通过实验证明此方案的正确性,该方案具有控制灵活、简单易行的特点。Battery management system （BMS） for electdc vehicle can not only manage battery but also control battery charger＇s charging current and voltage. Charger should be programmable to meet requirements when it is demanded to charge different batteries. Unlike the majority of studies, the charger varied the target value by changing the feedback ratio rather than reference. The study adopted digital and analog hybrid control scheme. Upper management system-BMS dominated digital potentiometers used in sampling system to change feedback ratio and the lower analog chip implemented control algorithms to reduce the BMS calculation cost. At last, experiments were performed to prove the correctness of the solution. The solution is flexible and easy to realize.
