Study on the Ultracapcitor Match and Control Strategy for Pure Electric Bus

摘要

This paper talks about the match and control strategy of ultracapacitors in the electric vehicle. It has beenrnproved the ultracapacitors can improve the dynamic capabilities of the electric vehicle (EV). So in thisrnpaper, an ultracapacitors bank control system for a pure battery electric vehicle is been implemented.rnFurthermore a kind of control strategy in this framework is also given in details. Thus the purpose tornallow higher accelerations of the vehicles with minimal loss of energy can be got. And the degradation ofrnthe main battery pack is also minimal. In the end, comparison between experiment with ultracapacitorsrnand that without ultracapacitors results is performed.
