Endesa and Nissan have today announced an agreement to give renewed impetus to electric mobility in Europe. The two companies have joined forces to launch onto the European market a commercially viable system of electric vehicles and charging infrastructure which allows a bidirectional power flow (V2G, Vehicle to Grid). V2G technology allows for an electric vehicle to be charged and used for its primary automotive purpose; while also offering consumers the flexibility to supply energy to their homes or even sell the unused energy onto the grid system (in countries where such a mechanism exists). Endesa and Nissan’s joint announcement paves the way for the two companies to work together so that today’s technological reality can become a commercial reality.
The proposal for cooperation is on a bidirectional charger from Endesa that may be activated in situ or from an external energy management system. An addition benefit of this system is the integration of energy generation not connected to the grid, such as solar panels and wind turbines, in countries where the appropriate regulation is in place.
Thanks to this system, a 100% electric model, such as Nissan LEAF or e-NV200, or another model compatible with version 2.0 of CHAdeMO (Quick Charging Of Electric Vehicles) can be charged in low-demand periods, benefitting from cheaper electricity tariffs. The option then exists to use the energy stored in the vehicle battery at home when electricity costs from the grid are higher, or alternatively to feed the energy back to the grid (in countries where regulations allow it).
Considering that electric vehicles have a capacity ranging from 10 to 100 kWh and spend more than 90% of their lives parked, systems such as V2G could play a significant role in the transformation of energy systems.
“Thanks to this technology, electric vehicles will become a fully integrated part of the electric system, adding new storage capacity and utilizing that capacity in the new and innovative ways, for purposes other than mobility”, José Bogas, CEO of Endesa, said.
“Through this agreement we will continue to join forces to expand the 100% electric vehicle and make it become a majority in Spanish roads. We also state that zero-emission technologies not only provide significant environmental benefits, but also involve a source of significant savings”, Marco Toro, CEO Nissan Iberia said.
Electricity is one of the very few types of energy that cannot be stored on a large scale. Therefore, the energy generated must be consumed or it will be lost, meaning that much of the electricity generated at night in wind farms for instance (when they are usually more active) cannot be used. However, with the integration through V2G technology of electric mobility, all this energy might be used to charge electric vehicles at night, making the system much more efficient. The new possibility that opens up with innovative systems such as that developed by Endesa, and with electric vehicles such as those from Nissan, will further balance production and consumption.
The agreement therefore represents a major step forward for the development of smart cities, which need tools to optimize production and distribution, better balancing supply and demand between manufacturers and consumers.
This agreement, which was signed at the Geneva International Motor Show, includes other joint action areas:
- Study of the possible re-use of electric vehicle batteries (second useful life) so that, once their function in an electric vehicle ends, they can continue to be used for less intensive purposes before they are recycled –for instance, energy storage.
- Design and evaluation of innovative offerings of electric energy and mobility packages both for the residential segment (B2C) and for companies (B2B).
Development of electric mobility in the Enel Group
For Enel and Endesa, the drive of electric mobility is a cornerstone in their future strategy and also a commitment for the sustainable development of its business. The group is currently developing innovative solutions for electric mobility and is also involved in major international projects to promote the diffusion of electric mobility in the countries where it operates, in particular Europe and Latin America. Today, the Enel group is one the most important operators of the charging infrastructure in Europe, with over 1,600 charging points, established mainly in Italy and through its Endesa subsidiary in Spain. It also has the real-time electric mobility management (EMM) platform, though which the charging points of the group are connected to those of other operators in Spain, Italy, Romania and Greece (e-roaming).
Nissan and sustainable mobility
Symbiosis between people, vehicles and nature: this is how Nissan defines its environmental philosophy, based on promoting sustainable mobility and electric vehicles. Nissan works pro-actively to face environmental challenges and contribute to reduce the emissions from its vehicles and its corporate activity.
Through Nissan Green Program 2016, the environmental action plan of the company, the objective of Nissan is to consolidate its leadership as manufacturer of zero-emission vehicles. To achieve this, the objectives set in the program are to improve efficiency in fuel consumption by 35% (to date it has been able to reduce it by 31.5%), reduce CO2 emissions from corporate activities by 20% per vehicle (this percentage is around 15.4%) and minimize the new natural resources including 25% of the material recycled in 2016 (Nissan achieved in Japan a material recovery rate of 99.5% in 2013).
