Elli and MITNETZ STROM publish concept for smart grid integration of EVs

Green Car Congress

Elli, a brand of the Volkswagen Group, and MITNETZ STROM have launched a nationwide pilot project for smart grid integration of electric vehicles. An algorithm uses price incentives to compare the cars’ charging plans with regional electricity output from renewable energies and the available capacities in the distribution grid.

How Smart EV Charging Will Help Promote Renewable Power Generation

Wallbox

The proportion of grid electricity generated by renewables such as wind and solar energy fluctuates depending on how hard the wind is blowing or how strong the sun is shining. This can lead to a huge variation in the grid power available, which can be a problem for power companies. How EVs can help balance the grid.
