摘要

针对采用串联充电方案的串联蓄电池,提出了一种基于降压升压拓扑的非耗散平衡充电电路。与每个电池相关的子电路充当电流分流器,将过量的充电电流从饱和电池转移到饥饿电池。为了使电池间的充电状态均衡,平衡充电电路以动态的方式调节平均充电电流。通过实验验证了该方法的适用性。

Balance charging circuit for charge equalization
A nondissipative balance charging circuit based on buck-boost topology is proposed for charge equalization control for the series-connected batteries with serial charging scheme. The sub-circuit associated with each battery acts as a current diverter to divert the excessive charging current from the satiated batteries to the hungry ones. To equalize the state-of-charge among the batteries, the balance charging circuit regulates the average charging current in a dynamical manner. The applicability of this approach is confirmed by experiments.
