As more electric vehicles come onto the roads, eventually that will mean millions of used batteries. According to the Center for Sustainable Energy (CSE), EV batteries will only power a car for eight to 10 years—but after that, they still have significant capacity remaining. Finding a way to put those batteries back into service is key to making them affordable.

Located in Hamburg, Germany, the project uses 2,600 used battery modules from 100 vehicles, primarily for frequency stabilization.

By “extracting additional services and revenue from the battery in a post-vehicle application, the total lifetime value of the battery is increased, and the cost of the battery can be shared between both the primary and secondary users.”
