Nissan and Endesa: to go for a vehicle-to-grid system

    Share
    Nissan and Endesa, an Enel Group subsidiary, signed a ground-breaking agreement at the 85th Geneva International Motor Show that paves the way for a mass-market vehicle-to-grid (V2G) system.



    The two companies have pledged to work together to deliver a V2G system and an innovative business model designed to leverage this technology. They have agreed to collaborate in the introduction of V2G services in the European markets, 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.

    Paul Willcox, Chairman of Nissan Europe, praised the innovative two-way charging system and the step-change towards a further acceleration of the EV market: ‘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.'

    Indeed, one of the main challenges for electricity management systems is to assure grid stability. This situation is especially relevant in countries with a high level of renewable energy generation, and this will only increase in the future. The longer term zero-emission vision is for EVs to be at the center of a fully integrated system whereby 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.

    "The flexibility offered by V2G implementation in terms of storing and releasing green energy into the grid will further enhance the already significant and tangible benefits of electric mobility. This is why Endesa, together with its parent company Enel and partner Nissan, have decided to join efforts in promoting this technology." said Javier Uriarte, Head of Market Iberia at Endesa.

    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 has developed the ultimate low-cost V2G technology ready for the mass market after years of real-life testing. The company 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.

    On March 12, 2015, as the culmination of the V2G system development, together with Nissan as automotive partner, Endesa will host a full demonstration of the market-ready and low cost system in Madrid.
