中文摘要：

通过两阶段充电时间序列设计与试验研究，分析充电电流分别与碳基超级电容器的实际电容量、有效储能量和充电效率之间的定量拟合关系。在室温条件下，实际电容量与充电电流的定量关系比较符合指数函数描述，拟合曲线的相关系数均大于0．99；标称电容量为0.5MF的碳基超级电容器在充电电流小于220A的条件下保持着较高的储能水平，但当充电电流超过220A，该超级电容器的总有效储能量急剧衰减，这表明超级电容器的最佳储能水平受充电参数优化范围的制约。

英文摘要：

Based on the charging design of time series with two stages and testing study, the quantitative fitting relationship, which charging current related respectively with actual capacitance of carbon-based supercapacitor, available storage energy and charging efficiency, was analyzed. At room temperature, the quantitative relationship between actual capacitance and charging current was described by exponential function, and its related coefficient is not less than 0,99 A carbon-based supercapacitor with nominal capacitance 0,5 MF can hold better energy storage level when the charging current was less than 220 A, When beyond 220 A, the total available storage energy is decreased remarkably, These show that optimal energy storage level of supercapacitors is limited by the range of optimization charging parameters.
