In order to reduce CO2 emissions of the transportation sector, all over the world, but specially in the European Union, environmental legislation has become more and more stringent, so that electrification seems to be the future of transports. For this reason, during the last decade, OEMs started offering more Battery Electric Vehicles (BEV) to their customers. However, the spread of this kind of vehicles on the market is still slow, mainly due to the range anxiety, the fear that the battery capacity is not enough. That is why, other than the improvement of battery technologies, OEMs work on the optimization of all vehicle’s sub-systems, so that their impact on the driving range is reduced.
