Nissan Vehicle-to-Grid technology

Nissan is to begin trials in the UK of a new “Vehicle-to-Grid” system, which allows electric car owners to use some of the power in their Nissan LEAF to feed back into the National Grid at times of peak demand.

80% of drivers in the UK travel less than 30 miles a day, which means that owners will only be using a small proportion of the total battery capacity for driving. Nissan’s idea is that this spare capacity can be fed back to the National Grid, in return for a financial reward from their electricity provider.

If the grid has spare capacity, then the LEAF will be able to charge, at times when there is less demand, and electricity costs are lower. By acting as a buffer, the electric cars are able to reduce requirement for importing electricity from “dirty” sources such as coal or gas power stations.
