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

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。
