Hybrid and electric vehicles constitutes one of the most innovative and trail-blazing sectors of automotive technology. Aspects such as the exhaustion of fossil fuels and global climate change have brought the topic to the forefront of public opinion. Research developments have advanced to the point where the global market breakthrough for electrically powered vehicles is inevitable in the very near future.  Current developments are showing that politicians as well as vehicle manufacturers have seen the signs of the times and authorisation of electric vehicles is increasing throughout the globe.  At the same time, such developments are opening up the need for mechanics specifically trained in this new and challenging technology. With electric power, electrical engineering and electronics will finally be the overwhelming aspect in vehicles.Among the electrically powered vehicles available, the most popular drive concept is that of hybrid vehicles.
Hybrid vehicles, by definition, have two drive options, which can be activated or deactivated depending on the
situation or operating status of the vehicle. Usually the vehicle includes both an electric drive system and an
