摘　　要：通过超级电容等效电路模型,分析了超级电容组不同充放电模式下的充放电效率。提出了超级电容组充放电效率的计算方法,在提供的总能量为80 k J,放电功率为50 k W,放电因数为50%条件下,研究了超级电容组的容量配置。仿真获得了超级电容组的效率曲线以及超级电容组所需器件组数曲线。研究结果表明:无论是恒电流还是恒功率充放电,为获得高效率,超级电容组充电电流须限制在210 A以下,放电电流不得超过190 A;充电功率需限制在10.6 k W以下,放电功率不得超过9.5 k W;超级电容组在容量配置时考虑效率就会导致所需器件组数的增加。试验曲线与仿真曲线基本吻合,表明了仿真方法的正确性。According to super capacitor equivalent circuit mode,charging and discharging efficiencies of super capacitor models with different charging and discharging modes were analyzed. A numerical method to calculate the efficiency of these charging and discharging modes was inducted. When the total energy was 80 k J,the discharging power was 50 k W,and the discharging factor was 50% for the super capacitor models,the capacity configurations were proposed. The number of devices required for group and the efficiency curves of super capacitor were retrieved by simulation. The results show that the values of charging current of super capacitor models must be limited to 210 A,and the discharging current is not exceed 190 A. The charging power is required to be restricted below 10. 6 k W,and the discharge power should be not exceed 9. 5 k W to achieve high efficiency whether constant current or constant power charging and discharging. When considering efficiency the capacity configurations of super capacitor models will lead to increase in the number of devices required for group. Experimental curves are consistent with the simulation curve,which indicates the correctness of the simulation method.
