电动车用超级电容器充放电性能的实验研究

Experimental research on carbon based supercapacitors?character of great current charge and discharge

为加速我国电动车用超级电容器的应用,了解其大功率、大电流充放电特性,本文通过对超级电容器的充放电实验,分析比较了几种常见的充放电模式,提出了恒压控制下充电电流的恒流惯性概念。详细的探讨了电容大电流充放电导致的电压突变、充放电量不充分、发热严重等问题及其可能的产生原因,并提出了可行的解决方案。

To realize the supercapacitors?character of great current charge and discharge,improve the supercapacitors for electric vehicle applications in our country。By the research of experiments on charge and discharge of commercial supercapacitors used in Electric Vehicle , several methods of charge and discharge are discussed and compared,a new concept——the inertia of current in the control of constant voltage is put forward。The Paper describe the problems and reasons in detail that the great current brings,which including the sudden change of voltage ,inadequate charge and discharge,seriously heat,etc,and put up the probable solutions。
