Abstract: Under the pressure of both environmental pollution and energy crisis, the development of EVs (electric vehicles)
has been taken on an accelerated pace all over the world. The drive efficiency of EV, which has a significant effect on the
rideability, energy cost and driving range, is a very important performance parameter. Based on the whole vehicle dynamical
model of EV and simulation, the drive efficiency of the front-wheel drive, the rear-wheel drive, single-motor drive and double
in-wheel motor drive was studied, respectively. The high efficiency drive mode of EV is obtained.
