Existing EVs Could Steer Energy To 300,000 Homes

The title of this post, is the same as this article on the Utility Week web site.

This is the opening two paragraphs.

Existing electric vehicles (EVs) in the UK could contribute more than 114MW to the National Grid, enough to power over 300,000 homes.

Research commissioned by Ovo Energy suggests the figure could be achieved based on the current 19,000 Nissan Leaf EVs registered in the UK using new vehicle-to-grid (V2G) chargers.

The article goes on to discuss this in detail.

So what is vehicle-to-grid?

Wikipedia has this summary.

Vehicle-to-grid (V2G) describes a system in which plug-in electric vehicles, such as electric cars (BEV), plug-in hybrids (PHEV) or hydrogen Fuel Cell Electric Vehicles (FCEV), communicate with the power grid to sell demand response services by either returning electricity to the grid or by throttling their charging rate.

Vehicle-to-grid can be used with gridable vehicles, that is, plug-in electric vehicles (BEV and PHEV), with grid capacity. Since at any given time 95 percent of cars are parked, the batteries in electric vehicles could be used to let electricity flow from the car to the electric distribution network and back. This represents an estimated value to the utilities of up to $4,000 per year per car.

If you are thinking about buying an electric car or van, read the article and other sources. Wikipedia seems a good start.

At its simplest, it would appear that if you buy an electric vehicle, it would be prudent to fit a V2G charger in your garage or parking space.

I would expect, that the charging system is sophisticated, so that if you want to use the car, there is sufficient charge and the power hasn’t been sold back to the grid.

It will be very interesting to see how this technology develops.
