摘　　要：为了实现对串联锂离子电池组进行均衡,研究了常用的均衡电路和电池均衡策略。基于模糊控制理论和传统PID控制理论,设计了一种模糊PID自适应控制的电池均衡器,用于锂电池组的电压均衡。通过MATLAB/Simulink仿真出模糊PID自适应策略和平均值法均衡策略下的电压曲线进行对比分析,结果表明,设计的模糊PID控制器均衡模块能有效降低锂电池组电压均衡的时间,均衡后的电压曲线拟合分布相对集中。The common used equalization circuits and battery equalization strategies are studied for the balance of serial lithium-ion batteries. Based on the theory of fuzzy control and traditional PID control, a battery equalizer for lithium battery voltage balancing is designed. Compared voltage curves under the fuzzy PID strategy with the equilibrium strategy by the MATLAB/Simulink ,the re- sult shows that equalization module based on fuzzy PID controller can reduce the time of the lithium-ion batteries voltage equalization. At end of equilibrium, the distribution of the voltage curves is more concentrated.
