摘要
针对大容量锂离子蓄电池组的均衡管理要求,文章提出一种基于多绕组变压器的主动均衡拓扑电路,采用固定占空比控制,通过多绕组变压器将串联蓄电池组中电压较高单体的能量传输到电池组中,从而实现单体之间的电压均衡。采用Simulink软件进行了仿真验证,结果表明:多绕组变压器均衡电路电池组可以实现大电流快速均衡。该方法可为卫星上大容量电池均衡设计提供参考。
In regard to the balance management for high capacity lithium-ion battery packs in space,an active balance circuit based on the topology of multi-winding transformer is proposed in the paper.The circuit can control the magnitude of the balance current by fixed duty cycle control,to achieve active balance function.The circuit can achieve battery voltage balance by multiwinding transformer,transmitting higher voltage battery energy to lower voltage battery.A Simulink model is built for the circuit,and the simulation results show multi-winding transformer balance circuit can achieve large current and fast balance.Meanwhile,the method could offer a design reference for high capacity Lithium-ion battery packs in the satellite.
