BMW has a couple of initiatives to give a second life to used battery packs from its electric vehicles. Earlier this year, the German automaker announced a wall mounted battery storage system, not unlike the Tesla Powerwall, using BMW i3 22 kWh or 33kWh battery packs.

The new power station is located in Hamburg, Germany. It uses 2,600 battery modules from more than 100 electric vehicles for a total power capacity of 2 MW and a storage capacity of 2.8 MWh.
