Electric power conservation technologies for electric vehicles have been an active area of research mainly for purpose of cruising range extensions. In the present study, the energy loss owing to dissipation by slippage during acceleration is studied and analytical solutions are derived. The energy conservation method via driving force distribution for an accelerating four-wheel drive vehicle is investigated. The driving forces are distributed such that the slip ratios of the front and rear wheels are equalized. It is quantitatively confirmed by the numerical simulations that the energy loss in a four-wheel drive vehicle can be less than half of that in a front- or rear-wheel drive vehicle.
