基于时分隔离技术的充电模式的研究

Research on charging method based on time-division isolation technology

时分隔离技术能有效实现对并联蓄电池组的电气隔离,同时可将组合开关电源对并联蓄电池组充电模式改变为脉冲充电。构建了铅酸蓄电池的充电模型,并对恒流充电和脉冲充电两种充电方式进行技术分析和仿真对比,结果表明,脉冲充电较恒流充电能够有效提高充电效率并优化充电性能,为时分隔离技术的推广与使用提供了重要的理论依据。

The electrical isolation of the parallel battery unit efficiently could be realized by time-division isolation technology. The charging method could be transformed into pulse-current charging by switch power supplies for the parallel battery unit. The charging model of lead-acid battery was constructed, and constant-current charging with pulse-current charging by simulation was analyzed and compared. The results show that pulse-current charging has a higher charging efficiency than constant-current charging and optimizes the charging performance, providing important theoretical basis for extending and using the time-division isolation technology.
