摘　　要：大规模串联超级电容器组中电容单体电压不均是影响超级电容储能技术发展的一个重要因素,实现超级电容串联时电压均衡是有效提高电容容量利用率,使用寿命,提高储能系统的可靠性。讨论了目前超级电容器均压的一般方法,并且提出了一种均压的新思路,同时省略了复杂的检测电路,从而减小了均压电路的复杂性,且详尽的分析了均压电路的工作原理,并且通过仿真验证了方法的可行性。A lot of cell to cell voltage imbalance of supercapacitors is one of main reasons for impeding the development of supercapacitors energy storage application, and voltage equalization can increase availability of supercapacitors capacity,prolong the lifetime of supercapacitor and improve the reliability of the energy storage system, this paper discussed several voltage balancing methods, and proposed a novel voltage imbalance idea, the idea has no voltage detection circuit,which significantly reduces the complexity of the systeam. Base on analyzing the operation principle of the voltage equilibrium circuit, and accreditation feasibility through simulation.
