Challenges for distribution grids

It is estimated that by 2015, about 5 million electric vehicles will be on the road all over the world, the majority of these in the EU. Also, facilitated by European climate policies to significantly reduce CO˛-emissions by 60 % in traffic until 2050 and to reduce the use of “conventional” vehicles in urban traffic by 50 %, technological advances and new mobility concepts as well as a steadily rising oil price, it can be assumed that the use of electromobility in Europe will generally increase. Simultaneously, the feed-in from DER is also expected to dramatically increase in order to meet the goals of EU and national climate protection policy. Therefore it can be expected that distribution grids will need to significantly increase their hosting capacity to accommodate fluctuating supply and mobile loads, i.e. EVs.


A large-scale EV introduction will moreover only be successful if the expectations of customers are met and current constraints are overcome. This requires not only further technological development but also the intense cooperation of all stakeholders, including OEMs, DSOs and energy service providers, to for example operate a sufficient network of (fast) charging infrastructure.
