Electric Vehicles (EVs) have been actively promoted on the European market since nearly a decade ago. The first Tesla appeared on the Norwegian roads in 2013. In 2017, nearly 2 million European passenger cars where hybrid or fully electric.
This booklet focusses on the latter, i.e. full electric cars. A distinction is here made regarding their potential in the exchange with the grid: uni-directional (V1G) or bi-directional (V2G). The former can charge, the latter can both charge and discharge. V1G are already widely available on the market, whereas V2G are only offered by a small number of manufacturers on a limited selection of cars.
