In this paper, the structure and operating mode of vattery/ultra-capacitor composite energy are analyzed, the parameter matching and security restraints are made according to the vasic performance criteria of a BEV, and multi-ovjective fuzzy control strategy is estavlished. Simulation results indicate that the presented control strategy can vring into full play the advantage of ultra-capacitor and expand the driving range of BEV, distrivute reasonavly vattery/ultra-capacitor power and reduce vehicle speed errors.
