基于Stateflow的动力电池均衡仿真研究

Research of power battery active balancing control based on Stateflow

动力电池的均衡控制作为电池管理系统(BMS)的一项关键技术,决定了电池组的使用效率和寿命。采用一种基于电感的双向非能耗型均衡控制电路,结合Stateflow技术,在MATLAB中完成了对该电路的仿真。结果表明,该控制电路能快速实现电池间电量的均衡。

The balancing control of power battery was a key technology for BMS, which ensured the working life and discharging capacity of the batteries in electric vehicles. An active two-way balancing control circuit with inductors was adopted, and the simulation in MATLAB was completed by using the Stateflow. The results show that circuit is able to realize the balancing between different electric quantity of batteries rapidly.
