The electric vehicle offers some very significant advantages compared to the conventional combustion engine. The most important of which is the improvement in overall energy efficiency. As such, from the extraction of primary energy to the wheels of the vehicle – From Well to Wheel – the battery-run electric vehicle makes use of up to 77% of the energy (if charging takes place using renewable energy sources) and 28% (if charging takes place using the electrical grid), compared to a current use of 15% by the combustion engine vehicle.
Moreover, the maintenance cost is greatly reduced and cannot compare with the maintenance or wear and tear of the vehicle with a combustion engine. Furthermore, CO2 emissions are considerably diminished and, if in addition, battery charging takes place via the use of renewable energy, it is almost possible to reach a level of zero emissions.
Within the framework of the project “Efficient Electric Mobility” being carried out by the Endesa Red-UIB Research Chair in Energy Innovation at the Universitat de les Illes Balears, electric consumption models are being developed for vehicles that are already in the market. These models provide instant power values, on the basis of certain physical and environmental variables plus driving habits that calculate the electric consumption of a vehicle under specific conditions.
