Nowadays, most automobiles are directly driven by internal combustion engines (ICE), which consume a lot of oil and cause severe pollution. But at the end of the 19th century, there were actually more electric vehicles. Unfortunately, they lost the competition because of their low efficiency, power density, and controllability at that moment. However, with the great development on the technologies of batteries, power electronics, and electrical machines, the focus has reverted to electric vehicles since the end of the 20th century.

System designers of electric or hybrid vehicles usually prefer to adopt wheel-hub or in-wheel traction motors, i.e. to put electrical motors aside or inside the vehicle wheels. By this means, the mechanical axes can be removed to reduce the total weight and enlarge the cargo space. Another benefit of implementing such a traction system is that the power generated during cruising and braking can be returned to the batteries and reused for the acceleration later.
