Self Study Program 499 – Basics of Electric Drives in Automobiles

VAG SSP 499. This self-study programme describes the realistic hybrid and electromobility concepts and the basics of high-voltage qualification for service staff. The Touareg 2011 sees Volkswagen supply a production vehicle with an electric hybrid drive. The new technology requires special training for handling and working on high-voltage vehicles.

According to current estimates, 2050 will be the last year of oil extraction as we know it. The technology required for oil extraction will then become extremely complex. For this reason, we need to use resources cautiously and efficiently. The task of “Think Blue.” is to educate people and create an awareness of resource conservation. The use of energy and raw materials requires constant optimisation.

The burden on the environment needs to be continually reduced at a steady rate. The aim is to prevent the global temperature rising more than 2°C by the year 2050. In order to reach this goal, the output of greenhouse gases like, for example, carbon dioxide (CO2), must be curbed.

Unlike vehicles with combustion engines, vehicles with electric drives do not produce exhaust gases during operation. This property alone makes electric vehicles more environmentally friendly than vehicles with conventional technology. However, the electrical energy for charging the vehicle does have to be produced from renewable sources, e.g. from wind, solar, hydroelectric or biogas power plants. One further aspect is the low energy costs for a journey of 100km with an electric drive compared with a conventional vehicle.

By the year 2020, at least one million electric vehicles will be driving on Germany’s roads. The German government underlined the importance of this issue in Germany by introducing a national electromobility development plan (Nationalen Entwicklungsplan Elektromobilität, NEPE) in August 2009. The electrification of vehicles will therefore rise steadily. An initial step will see hybrid vehicles that combine the advantages of both the electric motor and combustion engine systems. By combining the drives, the overall efficiency of the vehicle is improved and fuel consumption is reduced.
