[동력전달계부문] 에너지 평형식을 기초로 한 하이브리드 차량의 엔진/모터/배터리 용량 매칭 = The Engine/Motor/Battery Sizing of a Parallel Hybrid Electric Vehicle Based on Energy Balance Relation

다국어 초록 (Multilingual Abstract)

In HEV(hybrid electric vehicle) that has usually two power sources such as chemical and electric energy, It is an important and difficult issue to quantify the fuel-economy, however, there is no standard method. In this paper, we present the fuel-economy improvement index a of HEV against baseline ICV(internal combustion vehicle). Namely, this index is not absolute value but relative value. For this purpose, first, we assume that the engine of ICV operates at only one point. From the reasonable result of this assumption, we assume that the engine of parallel HEV operates at two points, discharging and charging points, which can be selected to satisfy energy balance relation that makes the total consumed energy from battery in discharging be equal to the total stored energy into battery in charging. Second, through these assumption, we can obtain 3-D fuel-economy improvement index map, a map will two non-dimensional variables, that is, the discharging time over total time and the engine power in discharging over average required power in driving. Finally, we obtain the 3-D a map of parallel HEV according to its engine, motor, and battery sizes in urban and highway driving cycles, and use these results to select the most appropriate component size.
