Renault to offer used EV batteries for home energy storage

Renault will give used EV batteries new life.

Following in the footsteps of Tesla and Mercedes-Benz, French automaker Renault has announced plans for its own home-based energy storage system.

Renault announced on Monday plans to partner with Powervault to offer second life electric vehicle batteries for home energy storage. Powervault will initially use the second-hand car batteries on a trial basis for 50 customers. However, if the project proves successful, it could offer a wider rollout.

Once the batteries' useful life has been expired, they will be returned to Renault for recycling. Renault estimates the second life batteries are capable of home storage duties for about 10 years.

"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,” said Nicolas Schottey, Program Director, EV batteries and infrastructures at Renault. "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.”

One key advantage of the Renault-Powervault alliance is cost. Without the need to produce an all-new battery for the Powervault unit, the Renault batteries can be offered at a 30 percent discount.

Renault is the third major automaker to join the home energy storage revolution. Tesla has been int he game for some time now with its Powerwall while Mercedes-Benz just joined the fray in the United States through a partnership with Vivint Solar.
