The new challenges of reducing the fuel consumption and the pollutant emissions are leading the transport sector towards a paradigm shift. Among the sustainable alternatives to the carbon fossil dependency the electrification is one of the most appealing solutions. In fact, the technological progress, especially in the power electronic field, is making ectrified vehicles increasingly attractive for the mobility scenario. Nevertheless, some know-how limitations, as the ones related with the battery energy density, represent the current obstacle for a massive penetration of the fully electric vehicle (EV). Consequently, in the near future the market will be likely dominated by the hybrid electric vehicles (HEV).
