Range extension control system for electric vehicles based on front and rear driving force distribution considering load transfer

Electric vehicles (EVs) are more highly efficient than internal combustion engine vehicles. However, EVs have a disadvantage in that the mileage per charge is short. In this paper, a range extension control system (RECS) based on a load transfer is proposed. The minimum acceleration resistance can be realized through driving force distribution ratio between front and rear wheels. Therefore, the proposed RECS fulfills maximum efficiency. Simulations and experiments are carried out to confirm the effectiveness of the proposed system.
