Hybrid and electric vehicles need energy storage for load leveling and efficient power management, and while batteries have been the norm, ultracapacitors are increasingly considered as alternatives. The study seeks to decide whether an energy storage unit should comprise only batteries, only ultracapacitors, or a hybrid of both. It introduces a methodology to determine the optimal composition of the energy storage unit. The authors demonstrate feasibility through an example and provide a cost analysis of the various energy storage configurations.
Hybrid and electric vehicles (HEV, EV) require some form of energy storage in order to achieve load leveling or efficiently manage power flows, mainly when accelerating or decelerating. Traditionally, batteries have been used but recently ultracapacitors have become potential candidates for energy storage in HEV/EV applications. To this end, this paper first presents a methodology for determining whether an energy storage unit (ESU) should consist of only batteries, only ultracapacitors or a combination of both. An example illustrates the feasibility of the proposed ideas. Finally, the paper concludes with a cost analysis of the different ESU alternatives.
