EV 시스템 효율 향상을 위한 시뮬레이션 연구

다국어 초록 (Multilingual Abstract)

Electric Vehicles (EVs) are the most promising candidates for the next generation of transportation because of the zero emission, higher efficiency than internal combustion engine vehicles, independence from petroleum, ability of recovering the braking energy, and silent driving. An EV usually uses an electric motor for traction and a battery for its energy source. The methodology for the sizing of an electric motor and a battery is introduced as well as for the selection of a final gear ratio. For an EV, improving its system efficiency is significant since its energy source is a huge issue these days. Two methodologies for improving EV system efficiency are presented and evaluated by backward simulation. Inverter loss model is constructed and applied to forward simulation to evaluate the efficiency of the inverter. Three different braking algorithms are presented and compared to each other by forward simulation.
