Real life vehicle-to-grid seeks market opportunities

Parked electric vehicles plugged into the electricity network with charged batteries could sell stored power back through the network. Nissan is the first to qualify a car battery system to sell its stored power into an existing market for primary regulation services to maintain grid frequency

IN THEORY
Parked electric vehicles plugged into the electricity network with charged batteries could be enabled to sell stored power back through the network

Uncertain future for selling electricity to the grid from electric car batteries because of uncertain value of doing so

NEXT STEP
More research into power system needs and the impact on networks of charging electric vehicles ...
