주행모드 및 환경 조건에 따른 전기자동차 성능 특성에 관한 연구

All-electric vehicles (EVs) use a battery to store the electrical energy that powers the motor. EVs are sometimes referred to as battery electric vehicles (BEVs). EV batteries are charged by plugging the vehicle into an electric power source. Although most electricity production contributes to air pollution, the vehicle environmental agency categorizes all-electric vehicles as zero-emission vehicles because they produce no direct exhaust or emissions. Because EVs use no other fuel, widespread use of these vehicles could dramatically reduce petroleum consumption. Currently available EVs have a shorter range per charge than most conventional vehicles have per tank of gas. EV manufacturers typically target a range of 160 km on a fully charged battery. The efficiency and driving range of EVs varies substantially based on driving conditions and driving habits. Extreme outside temperatures tend to reduce range, because more energy must be used to heat or cool the cabin. High driving speeds reduce range because of the energy required to overcome increased drag. Compared with gradual acceleration, rapid acceleration reduces range. Additional devices (air-conditioner and heater) significant inclines also reduces range. Based on these driving modes and climate conditions, this paper discusses the performance characteristics of EVs on energy efficiency. And this paper assesses the driving range per charge and maximum speed of EVs.
