Nissan electric vehicle owners in the UK will soon be able to sell the extra energy stored by their cars back to the national grid.
Vehicle-to-grid is a system through which battery-powered vehicles communicate with the power grid either to charge the cars when the cost of electricity is lower or to sell back the stored extra-juice during peak hours to earn some cash. Nissan and the power company Enel are recently said to launch a trial for such a network link in the United Kingdom. Their plan is to fit and connect one hundred V2G units at locations agreed by private and fleet owners of the Nissan Leaf and e-NV200 electric van. Therefore, owners will be able to plug their cars into the V2G system to have the flexibility and power to sell energy from their vehicle battery back to the national grid.
The automaker said that if all 18,000 Nissan electric cars in the UK were connected to the energy network, they would generate the equivalent output of a 180 megawatt power plant. If that was scaled up in a future where all the vehicles on UK roads are electric, vehicle-to-grid technology could generate a virtual power plant of up to 370 gigawatts, enough energy to power the UK, Germany and France all together.
Nissan also made another “electrical” announcement, as it said it teamed up with the power management company Eaton to introduce a home energy storage unit called the “xStorage” in Europe. Connected to residential power supply or renewable energy sources such as solar panels, the unit costs around 4,000 euros (4,500 dollars) for a nominal power of 4.2KWh and uses 12 second hand Nissan batteries. Nissan and Eaton said they expected to sell more than 100,000 xStorage units within the next five years.
