时序串联充电策略用多组蓄电池并联来满足功率需求,过高的并联数使系统体积、重量过于庞大不利于工程化.本文在普通时序串联电容充电方法基础上,提出一种快速充电优化方案,能够在保证充电速度的前提下降低并联数.首先并联电池组对电容充电,之后通过切换电路结构,将电池系统转化为串联继续充电,同时改变电路限流电感值保证电池处于极限工况.仿真结果表明,普通时序串联法与优化方法都可在3s内将600mF电容器充满,但优化方案将蓄电池并联数减少1/3,极大降低了系统成本、体积与重量.搭建充电策略优化的实验平台进行实验,实验波形与仿真波形基本一致.验证了优化方案的正确性,为混合储能更好地应用于大功率电磁发射奠定了基础.%Strategy of series-on-schedule uses parallel-connected batteries to meet high power requirement. It makes the system too big and heavy. This article constituted the improving scheme based on series-on-schedule strategy. Firstly, it paralleled the batteries to charge the capacitor. Secondly, it changed the configuration of batteries from parallel to series. At the same time, the inductance should be regulated to insure the batteries were in the utmost work status. The simulation results show both the series-on-schedule and the new scheme can charge the 600mF capacitor to requisite voltage in 3s, but the new scheme can cut down the number of batteries by 1/3. It reduces the spending, volume and the weight of the system largely. The experimental results show the simulation curves can match the real situation well. At last the conclusion can be drawn that the new scheme is validate and realizable.
