• Introduction of V2G services in the European market;

• Exploring the use of second-life EV batteries for stationary applications (including households, buildings, grid); and

• Designing and evaluating potential affordable energy and mobility pack offers.

This Vehicle to Grid (V2G) system consists of the Endesa two-way charger and an energy management system that can also integrate such off-grid, and renewable, power generation as solar panels and wind turbines. Using this equipment, a Nissan LEAF or e-NV200 owner can connect to charge at low-demand, and cheap tariff periods, with an option to then use the electricity stored in the vehicle’s battery at home when costs are higher, or even feed back to the grid with a net financial benefit. Electricity generated by solar panels or wind turbines can be used to charge a vehicle, to power the home or business, or to feed back to the grid.

Endesa will host a full demonstration of the market-ready and low cost system in Madrid on 12 March.

We believe this innovation represents a significant development for Nissan Leaf and e-NV200 customers. Every Nissan electric vehicle battery contains a power storage capability that will prove useful in contributing towards smarter and responsible management of the power demand & supply of local power grids, thus reducing our EV total cost of ownership. Not only does this represent an opportunity for Nissan’s EV private and fleet owners, it could also support grid stability and fully demonstrate that each Nissan EV represents a tangible social asset.

—Paul Willcox, Chairman of Nissan Europe

The longer term zero-emission vision is for EVs to be at the center of a fully integrated system through which owners can participate in wholesale energy markets using the power stored in the batteries of their electric vehicles, and thus significantly reduce their cost of operation. In a not-so-distant scenario, the EV user not only decides when and where they want to charge their EV, but how best they spend and re-sell the energy stored in their EV; receiving tangible financial benefits in terms of energy savings, while at the same time maximizing the use of green energy.

Endesa first showcased its V2G technology in 2008 in Smartcity Malaga, the Enel Group testing ground for smart cities. Later on, in 2012, Endesa presented the evolution of such technology at the ZEM2ALL demonstrator.
