摘要
为实现动力锂离子电池的高效快速充电,采用非耗散型的Reflex TM充电方法,消除充电过程中的极化现象,在分析改变充电电流参数对充电过程的优化作用基础上,提出一种变流变频充电控制策略.设计双向DC-DC变换器及其控制电路,实现可变流变频的Reflex TM充电策略.通过改变正负脉冲幅值和占空比等实验,验证其可行性和有效性.
To achieve the high-efficient and fast charge of a power lithium-ion battery,a non-dissipative charging method called as Reflex TM is adopted to remove the polarization phenomenon in the charging process. Based on the analysis of the optimization function of different charging current parameters on the charging process,the variable-current and variable-frequency control strategy is presented,and then a bidirectional DC-DC converter and its control circuit are designed to implement the strategy. The feasibility and availability of the strategy is proved through the experiment where the positive and negative pulse amplitudes and the duty-cycle are changed.
