Powervault is teaming up with Renault to test the French automaker’s used electric vehicle (EV) batteries as smart battery storage systems for its solar installations. The partnership is expected to reduce the cost of Powervault’s G200 lithium-ion battery system by 30 percent. The companies will conduct a trial at 50 homes, public housing and schools with rooftop installed in M&S Energy’s United Kingdom service area.
“Thanks to this home energy storage partnership with Powervault, Renault is adding a new element into its global strategy for second life batteries, which already covers a large number of usages from industrial to residential building and districts. The second life use not only gives additional life to electric vehicle batteries before they are recycled, but also allow consumers to save money. It’s a win-win-win: for EV owners, home-owners and the planet,” said Nicolas Schottey, program director, EV batteries and infrastructures at Renault.
Renault’s batteries generally have a life-cycle of 8 to 10 years in an EV. Once retired from the road, the batteries could see an additional 10 years of use in energy storage systems and with solar installations, according to Renault. That's all before the units are recycled. Prior to giving it a second life in an energy storage system, each battery from an EV unit is graded for performance, assembled into battery packs and integrated into a Powervault power storage system.
“The collaboration we are announcing today with these two household name brands–Renault and M&S, is an important milestone on our journey towards achieving mainstream adoption of home energy storage. Homeowners and brands are now looking to benefit from the smart power revolution. It’s only a matter of time before a Powervault becomes as common in UK households as a dishwasher,” said Joe Warren, managing director of Powervault.
Like other EV manufacturers, Renault is entering a solar energy battery storage market that is rapidly expanding and rife with potential. For instance, Tesla offers the Powerwall energy storage system and BMW has entered the residential battery storage market with its second life batteries when it introduced its 22-kilowatt hour, i3 battery system.
Powervault will lunch the test of Renault’s batteries in its G200 storage system over the next year. The companies will monitor the batteries' performance for energy cost reductions, overall system efficiency and how each system reacts to the grid. During the trial the companies will also collect customer reactions in order to develop a mass market roll-out of the product throughout Europe and eventually other countries, like the US.Tweet
