The case of an electric vehicle, where a motor and a battery system can be substituted for an engine and a transmission system, comprises a very fascinating power source. However, due to the low power performance of the motor system, the weight reduction of the electric vehicle for the increase of the efficiency is necessary. For the research of the new vehicle, the benchmarking of developments leading companies about the electric vehicle was considerably surveyed first. Then the CAE (computer aided engineering) simulation of the full vehicle (Metro by Geo Co.) model was performed. Among these systems, as the weight of the batteries are comparably high (200 ∼ 300 kg or over), the problem of the safety performance can occur where the motor and the battery are situated in the vehicle location (in the front engine room, center floor or rear trunk position). In addition, the reinforcement degree can differ following as the motor and the battery position in the vehicle in order to satisfy the vehicle safety and it can induce the weight variation of the vehicle. Therefore, the effect of strength performance on the layout of the power train system (mainly battery) was clarified by using CAE (computer aided engineering) and the optimized position of the power train system considering weight balancing of the electric vehicle was suggested in the present study.
