OVO Energy sent me a very nice birthday present yesterday via Twitter:

An early Christmas present from @OVOEnergy!

Is the system pictured doing full blown #V2G? How about #V2H without any export to the grid? Or perhaps it's actually doing festive Vehicle to Xmas Tree (#V2X for short)?

In an associated press release OVO announced:

Following the unveiling of the world’s first widely available, domestic vehicle-to-grid charger, at the Energy Technology Product Showcase in April, OVO can confirm it has successfully installed the first charger in a customer’s home.

Tom Pakenham, Director of Electric Vehicles, said: “We’re excited to install a vehicle-to-grid charger in a customer’s home. By developing vehicle-to-grid technology we’re enabling drivers to store renewable energy in their cars, use that to power their homes and to sell energy back to the grid at peak times, allowing our customers to earn rewards from smart charging their electric vehicle.”

By way of additional background information OVO added that:

The 6kW OVO Vehicle-to-Grid (V2G) Charger is the world’s first domestic bi-directional charger. It offers drivers of certain electric vehicles the opportunity to discharge excess electricity from their cars back to the electric grid to help supply energy at times of peak demand. It is the first such product to be produced and made commercially available at volume in the world.

Available to Nissan LEAF drivers with a 30 or 40kWh battery, the OVO Vehicle-to-Grid Charger could enable Nissan drivers to have free power for their electric vehicles by selling energy back to the grid. This is an important step for both companies to deliver their mission to offer customers free power for their electric vehicles.

This is part of the Innovate UK Vehicle-to-Grid competition, funded by the Office for Low Emission Vehicles (OLEV) and the department for Business Energy and Industrial Strategy (BEIS), in partnership with Nissan, CENEX, Indra and OVO.
