Nissan is launching a new vehicle-to-grid charging scheme in the UK with its all-electric Leaf that will enable owners to sell extra energy stored in their cars' batteries back to the electricity grid for money.
The car maker revealed at an event in east London that it has been working with the UK’s National Grid and global power management company Eaton to develop a so-called xStorage system, which can transfer additional energy from a Leaf’s batteries to the grid.
Nissan Europe chairman Paul Willcox said a fully charged Leaf can power an average home for two days and that contributing to the grid with xStorage can earn owners as much as £600 a year in income.
“Currently there are about 18,000 Leafs in the UK, with energy equivalent to about two power stations,” said Steve Holliday, National Grid’s non-executive director. “If everyone drove a Leaf, there’d be enough energy to power Germany and Britain.”
The xStorage system has been developed by Eaton and costs £3000 to be supplied and installed. It works in much the same way as a conventional Leaf charger does, but with energy moving in the opposite direction. Up to 4.2kWh of energy can be stored at one time.
