Endesa and Nissan Creating E-Mobility 2.0

Published on Monday, 16 March 2015

After previously being vehicles that consume energy electric cars are now turning into mobile batteries that store energy and inject it back onto the grid. Endesa and Nissan has brought about this revolution with the Vehicle-to-Grid (V2G) system, which was the focus of the agreement signed by the Enel Group business and the Japanese automotive manufacturer at the 85th. Geneva International Motor Show and whose commercially version was implemented on 12 March in Madrid.

The V2G solution developed by the Enel Group and Nissan includes an Endesa two-way charger and a management system that is compatible with renewable energy generation through autonomous plants, such as PV solar panels and small wind power turbines. These systems can be used by drivers to connect or recharge their Nissan LEAF or e-NV200 minivans in low-demand periods, benefitting from cheaper tariffs, while they also have the option of either using the stored energy or feeding it back onto the grid, which leads to savings for the consumer.

This way electric cars become mobile batteries that store energy when it's convenient or feed it either back to the grid or directly to our homes when it's needed or when energy costs more. With the V2G system cars are no longer only means of transportation but also energy carriers, not just drawing energy but also being an integrated part of the smart grid that can stabilise grid flows and play an active role in distributed generation.

The official rollout of the V2G system, with the demonstration of the low-cost system for the mass market, is the result of years of testing. The first practical demonstration of the technology goes back to 2008 and the Smart City Malaga project, while its development could be seen in the ZEM2ALL project in 2012. The eco-system surrounding Enel's e-mobility activities continues to push towards new frontiers, such as electric car battery recycling at a fast-recharge column in Malaga as part of the European Green e Motion project.
