The new 1.9 MWh ESS will be used to compensate fluctuations in the grid, counteract local peak demand and help prevent blackouts.

Audi is preparing for the utilization of old electric car batteries in energy storage (second-life use) through a series of pilot installations.

The latest one launched in EUREF Campus in Berlin, Germany is a 1.9 MWh/1 MW system, consisting of battery packs from Audi vehicles.

The system will take the role of a real-life laboratory and will compensate for the fluctuations in the grid (demand peak shaving) as well as optimize energy supply (charging to make use of excess electricity supply from solar and wind).

Having 1.9 MWh ESS will be a beneficial buffer also for the immediate vicinity of 175 kW DC fast charger.

Audi Opens Battery Storage Unit on Berlin EUREF Campus

  • 1.9 MWh storage unit consisting of used lithium-ion batteries is being connected to the grid
  • Germany’s largest multi-use storage unit compensates for fluctuations in the grid and optimizes energy supply
  • Real-life laboratory indicates potential for energy transition

Audi is electrifying the capital: In the context of the Formula E guest performance in Berlin, the brand with the four rings has opened up Germany’s largest multi-use storage unit on the EUREF Campus. The storage unit has a capacity of 1.9 MWh and uses used lithium-ion batteries from development vehicles to test various interaction scenarios between electric cars and the power grid. The objective: Intelligent networking to promote the energy transition.
