Coupling local renewable energy production with electric vehicle charging: a survey of the French case

International audienceThe share of renewable energy sources (RES) production in energy mixes, especially the ones of PV panels and wind farms, has been continuously increasing during the last few years. Similarly, a strong development of battery electric vehicles (EV) is expected within the next years. However, these two new innovations could trigger local security issues on electrical grids. One way to mitigate these problems could be to combine the charging periods of the EVs with the local RES production. This paper aims at analysing the possibility to implement this kind of smart charging strategy in France by 2020, taking into account the wide diversity of local energy mixes in France and their seasonal dependencies. The results show the achievable green charging ratio for the EV fleet per season and per region, with and without a smart charging strategy
