The faster and less complicated the charging process, the more likely people are to choose an e-vehicle. Therefore, there are several concepts for making "refuelling" electric vehicles easier in the future.
Together with its partners, innogy has already installed a large number of charging stations in service areas on German motorways. Currently, there are at least two charging points each at 130 locations. It is planned that by the end of 2017 a charging station will be installed in each of the 400 service areas. The fast expansion of the charging infrastructure is driven by a consortium of German car manufacturers that innogy collaborates with.
What is already a reality with many types of smartphones, could become the future standard for electric vehicles: wireless charging by induction. Coils in the floor create an electro-magnetic field that charges the battery of the e-vehicle. Charging points could thus be installed everywhere and invisibly in the future – at traffic lights and bus stops, at car parks and in the garage at home.
A 500-kilometre range and an 80 per cent battery charge in 15 minutes: this could become reality with "high power charging". With 350 kilowatts these charging points would be ten times stronger than most charging stations in use today. Test systems are already in use, more are currently being installed.
Invoicing for charging
In the future, no more manual operating steps at the charging stations may be required: with "car-e-wallet" the car automatically registers with the charging point when approaching it and then manages the payment process or invoicing with the energy supplier. This is already the reality for electric vehicles built according to ISO 15118. A smart charging lead (plug & charge) also enables direct communication with the charging point. innogy is collaborating with various car manufacturers to drive this topic forward.
