The technology includes a two-way charger, which means the vehicle’s battery can function as a backup energy storage system and feed electricity back into the grid at times of peak demand, avoiding blackouts.

Nissan and Endesa will work on the V2G system itself, including using batteries from end-of-life vehicles to store energy from renewables, and will develop a business model for it to take place. Essentially, the technology will enable electric vehicle customers to sell electricity back to utility companies, reducing ownership costs.

Paul Willcox, Chairman of Nissan Europe, said: “Every Nissan electric vehicle battery contains a power storage capability that will prove useful in contributing towards smarter and responsible management of the power demand & supply of local power grids, thus reducing our EV total cost of ownership.

“Not only does this represent an opportunity for Nissan's EV private and fleet owners, it could also support grid stability and fully demonstrate that each Nissan EV represents a tangible social asset.”

Javier Uriarte, Head of Market Iberia at Endesa, said: "The flexibility offered by V2G implementation in terms of storing and releasing green energy into the grid will further enhance the already significant and tangible benefits of electric mobility. This is why Endesa, together with its parent company Enel and partner Nissan, have decided to join efforts in promoting this technology."
