摘　　要：电池并联成组时,单体电池的不一致性会导致电池之间互充现象的产生,其频繁相互充放电致使电池组的寿命降低,需采取必要措施避免该现象的发生。在传统拓扑电路的基础上,提出了新型高效防互充拓扑电路,该电路通过判断电流状态,控制继电器消除二极管损耗,同时实现防互充的功能。基于该新型拓扑电路在MATLAB/Simulink搭建了仿真模型,通过仿真验证了新型拓扑电路在提高电池组电能利用效率的同时可防止单体电池间的互充,有一定的实际应用价值。The inconsistency of single batteries will lead to mutual charging when the battery packs are connected in parallel. And their frequent mutual charging and discharging will reduce the service life of the battery pack. Therefore, measures should be taken to avoid this. In this paper, a new high-efficiency anti mutual charging topology circuit is proposed based on the traditional topology circuit. The circuit judges the current state, controls the relay to eliminate diode loss, and realizes the function of anti mutual charging at the same time. And a simulation model is built in MATLAB/Simulink based on the new topology circuit. The simulation results show that the new topology circuit has certain application value in improving the utilization efficiency of battery pack and preventing mutual charging between single batteries.
