摘要:
针对目前的超级电容组充电策略存在过压风险和容量利用率较低的缺陷,在现有充电方法的基础上,提出一种动态分段超级电容充电控制策略,提高了超级电容容量利用率.该方法划分为恒流充电、恒压充电与浮充3个阶段,恒流充电又划分为启动阶段、恒流阶段与充电终止阶段,恒压充电根据单体电压动态确定,设计了状态机实现该方法.采用带有均压电路的串联电容组模型进行仿真实验以验证充电效果.仿真结果表明:该方法可将超级电容利用率提高9%.
Abstract:
The drawback of charging strategy for series connected supercapacitors is that the available methods are high over voltage risk,low available rate of capacitance and poor adaptability.By enhancing current charging strategy,a supercapacitor charging strategy based on dynamic segmentation has been proposed.This strategy has the advance that the available capacitance rate can be improved.The constant current charging step is divided to starting step,main constant current charging step and stair current step.The voltage of constant voltage step is dynamically decided by the voltage of cells.The transfer parameters of different step were computed.the state machine was designed to realize this strategy.The simulations are experimented with the model of series connected supercapacitors with balancing circuit.The simulation result proved that the voltage jumping up in the staring step and the voltage droping are restrained.The strategy improve the available capacity rate of supercapacitors to 9%.
