Renault starts piloting vehicle-to-grid charging in electric vehicles on a large scale

The project will use 15 of Renault’s Zoe EVs

Groupe Renault, the European leader in electric vehicles, is beginning the first large-scale pilot schemes in reversible electric charging. Our alternating-current technology has the particularity of placing the reversible charger inside vehicles, so it just requires a simple, inexpensive adaptation of the existing charging terminals.

A fleet of 15 Zoe vehicles with vehicle-to-grid charging will be introduced in Europe over the course of 2019 to develop Renault’s future offerings in reversible charging and lay the groundwork for the future standards.

These pilot schemes will begin in Utrecht (the Netherlands) in an ecosystem developed by We Drive Solar and on Porto Santo Island (in the archipelago of Madeira, Portugal) with Empresa de Electricidade da Madeira, an energy supplier. Following these, more pilot schemes will be introduced in France, Germany, Switzerland, Sweden and Denmark.

“With this initiative, Groupe Renault is fully fulfilling its role as a leader in electric mobility for all and as a player in the energy transition. Vehicle-to-grid charging is a key pillar of the smart electric ecosystems that Groupe Renault has set up. We have chosen onboard technology that also optimises the cost of recharging stations and thus facilitate a large-scale development,” announced Groupe Renault’s director of EVs Gilles Normand.

Vehicle-to-grid charging – also called reversible charging – modulates the charging and discharging of EV batteries in accordance with users’ needs and the grid’s supply of available electricity.

Charging reaches its maximum level when the electricity supply exceeds demand, notably during peaks in production of renewable energy.

But vehicles are also capable of injecting electricity into the grid during peaks in consumption. EVs can therefore serve units of temporary energy storage and become key drivers in the development of renewable energy.

In this way, the electricity grid optimises the supply of local renewable energy and reduces infrastructure costs. At the same time, customers enjoy greener, more economical consumption of electricity and are financially rewarded for serving the electricity grid.

Reversible charging will be piloted in several projects (electric ecosystems or mobility services) through seven countries and alongside various partners to lay the groundwork for Groupe Renault’s future offering.
