Electricity storage on wheels – integrating electric cars into the network

As and when more electric cars hit the roads, the electricity grid must be able to withstand commuters charging their cars at night. For this purpose, EWE is developing intelligent energy management for electric vehicles with partners from the energy- and automotive-sector in the ‘Controlled Charging 3.0’ project.

With own infrastructure, EWE has already demonstrated that e-cars can be harnessed as ‘storage on wheels’ for excess wind and solar power through the use of battery changing stations and batteries that can also feed electricity back into the network.
