Abstract—With ever-increasing oil prices and concerns for the natural environment, there is a fast-growing interest in electric vehicles (EVs) and renewable energy resources (RERs), and they play an important role in a gradual transition. However, energy storage is the weak point of EVs that delays their progress.
In hybrid energy storage-based EV, the foremost problems of EM due to load demand result in unpredictable drive range and wide variations in power request. The key goal of the EM is to minimize the absolute difference between power supplied and the power demand by HESS, that is, battery and ultracapacitor.
