Belectric has completed a 1.9 MWh battery storage system for Audi in Berlin’s Schöneberg district.
The company utilized 20 used lithium-ion batteries for the project, all of which were sourced from Audi’s test vehicles. The storage unit spans an area of roughly 110 square meters, according to an emailed statement. The system has been designed to test a range of applications between electric vehicles and the grid, as part of the Mobility2Grid research project.
“On the EUREF Campus, we’ve seen a present-day example of how the energy and transport sectors can work together effectively and compatibly in the future,” said Frank Amend, a member of Belectric’s management board who oversees the development of batteries and hybrid systems. “This battery storage system will allow Audi to provide an important link between volatile generation from renewable energy sources, different consumers and state-of-the-art power grids.”
Audi claimed the 1.9 MWh storage system is big enough to provide charging services for roughly 200 electric vehicles. It also said that the installation is capable of supplying electricity for the entire 5.5-hectare EUREF Campus for slightly less than two hours.
Belectric helped with system integration for the energy storage project, which was designed to handle a range of applications, such as stabilizing the grid and flattening peaks. The system will also provide specialized grid services such as reactive power compensation.
To date, Kolitzheim-based Belectric has built about 100 MW of storage capacity in Europe. Last June, it used thousands of new and used vehicle batteries from a range of manufacturers for 40 MW of energy storage projects in the U.K. and Germany. The systems are being used to provide grid services, such as primary control power.
