Nissan Leaf Gets Green Light for Vehicle-To-Grid use in Germany


Electric car is first to win regulatory approval from German authorities to supply energy from battery back to the grid

So-called vehicle-to-grid (V2G) technology is a connection between the EV and the grid through which power can flow from the grid to the vehicle and vice-versa. That potentially enables car owners to sell energy to the network, while utilities could use electric cars as a backstop if demand rises.

There will be 280 million electric vehicles by 2040, according to estimates by the International Energy Agency, compared with more than 3 million last year.

Guillaume Pelletreau, Vice President and Managing Director, Nissan Center Europe, said:

“We strongly believe in an emission-free future. … Leaf batteries could make an important contribution to energy transition in Germany and a sustainable future.”

Nissan is relying on the CHAdeMO charging standard, which has been jointly developed by several Japanese companies as a competitor to Tesla’s supercharger system and the European-backed Combined Charging System (CCS).

That puts Nissan at odds with European carmakers, including BMW and Volkswagen who are pushing to have the CCS, which is also capable of V2G services, established.

Thomas Raffeiner, chief executive and founder of The Mobility House, said:

“Nissan is ahead for now but other technologies, including Tesla’s supercharger can theoretically do the same thing.”

Nissan has so far sold about 370,000 electric vehicles and, along with top shareholder Renault, has been very active in exploring how car batteries can be integrated into the wider power system.

While a mass uptake of EVs is expected to put a major strain on the power grid and require billions of euros in infrastructure investments, car batteries have already proven that they can become part of the network.
