Abstract:

Electric vehicle (EV) technology is seen as a game-changer in the transportation industry since it provides benefits such as environmental friendliness, lower fuel costs, lower maintenance costs, energy efficiency, and greater safety. The design of the energy system is crucial to the electric vehicle's performance. The selection of appropriate energy storage resources is the initial step in the energy storage design. This article presents the various energy storage technologies and points out their advantages and disadvantages in a simple and elaborate manner. It shows that battery/ultracapacitor hybrid energy system technology is the most suitable for electric vehicle applications. Li-ion battery technology with high specific energy and range is very ideal for this application.
