A new method of using dynamic equalization technology to realize the maximum energy storage uti-lization was presented to overcome the influence of the disaccord among units of series super capacitor(SC) bank and ensure that the units could work safely.By considering in combination with the high spe-cific power,low working voltage,wide voltage working range and nonlinear external characteristics,wepresent constant duty ratio pulse frequency modulation mode and fuzzy control method based on state pre-diction in the active equalization circuit and accomplish the software and hardware design for the equaliza-tion system.The simulation analysis and experiment results of constant current multi-cycle and variablecurrent multi-cycle charge-discharge process verify the validity of the design.
