摘要
锂电池组均衡管理系统是合理、有效及安全使用电池组的基础,论文提出基于电池荷电状态(SOC)均衡的均衡策略,给出了均衡电路及DC-DC控制方法的选择,采用Thevenin模型作为电池模型,运用扩展卡尔曼(Kalman)算法估计电池的SOC值,最后通过Simulink仿真及试验结果,验证了所设计的均衡管理系统达到了设计目标。
The balanced management system is the basis of reasonable, effective and safe use of the battery pack.This paper put forward an balanced methods based on balance of the state of battery charged（SOC）. First of all, it chooses the equalization circuit and control method of DC-DC. Secondly, using thevenin model as the battery model, it estimate the SOC of the battery using the extended Kalman（Kalman） algo-rithm. Finally, the results of Simulink simulation and experiment demonstrated that the design of balanced management system has reached the design target.
