摘　　要：串联空间蓄电池组中各单体能量维持均衡是安全使用并充分发挥蓄电池组性能的重要保证。通过对几种主要均衡充电方法的优缺点进行分析比较,设计了一种双电源结构,采用可编程逻辑控制的顺序开关均衡充电系统,并使用Matlab对该方法进行了仿真,对其均衡效果进行了分析。研究结果表明:该均衡充电系统具有均衡速度快,可扩展性强的优点。To maximize performance and reliability, the individual space battery energy in a series connected pack must be fairly uniform. Based on the analysis and compare of several equalization circuits, a charge equalization system was proposed and simulated by Matlab. This system was consisted of double power supplies and sequential switches controlled by logistic program. The result indicates that the whole system achieves speedy and extendibility.
