Electric vehicle batteries can do more than power cars. In Lunen, Germany, thousands of old EV batteries are getting a new life as part of an energy storage facility.

These batteries will support renewable energy because they can supply power even when the wind isn’t blowing and the sun isn’t shining.

The project is a collaboration between automotive giant Daimler and two other companies. It will store 13 megawatt-hours of power – enough to run a small city.

It may sound strange to build a new power station that relies on old batteries, but it actually makes a lot of sense. Harold Kroger, Daimler’s head of electrics for Mercedes Benz cars, explains that even when an EV battery is too worn-out to run a car, it can still be put to good use.

KROGER: “The battery might not be in perfect shape anymore to drive a car, but it’s perfectly adapted to storing energy in a stationary way.”

Since batteries lose their potential to charge over time, Kroeger says there will be an abundant supply of used batteries when the EVs sold today turn ten years old.

Giving old batteries a second life might also make electric vehicles a little less expensive for consumers someday. And that could help drive the world towards a more sustainable transportation system.
