BMW and Bosch open new 2.8 MWh energy storage facility built from batteries from over 100 electric cars

September 23, 2016


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.

Today it announced that it completed and started testing, in partnership with Bosch, a new utility-scale energy storage facility again using used electric vehicle battery packs –  but the scale is much more impressive.

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.

The system is used to stabilize the grid and reduce the impact of peak demand. Vattenfall, the energy company operating the project, highlights the advantage of battery packs that can just turn on in a matter of seconds.
