DESIGNING ENERGY STORAGE SYSTEMS FOR HYBRID ELECTRIC VEHICLES

Every design problem faces the need to satisfy multiple objectives; in the case of designing energy storage systems for hybrid electric vehicles, the problem is no different. This paper presents a method to design an energy storage system by combining different battery and ultra-capacitor technologies. The choice of energy storage elements depends on the desired performance of the vehicle, and the efficiency, mass and cost of the energy storage system. From knowledge of the characteristics of battery and ultra-capacitor options, a Pareto set of optimal solutions is generated to help select the best energy storage system.
