Meeting with RWE Generations for the secondary use of electric car batteries, Audi will draw attention with its work.
Audi has commissioned an energy storage facility to use used lithium-ion batteries in its electric cars for their second life. The project, realized in collaboration with the RWE Generations company, marks a new era in the energy revolution. Within the scope of the project, the second life of the out-of-service batteries used in the development phase of the e-tron model is used in an energy storage facility. In the collaborative project, batteries with more than 80 percent residual capacity are still used after their first lifetime.
First details from the work of Audi and RWE Generations
These second lifetimes of the batteries are highlighted in this project as being extremely ideal for use in stationary power storage systems. We see that these batteries can have a second period of use of up to ten years, depending on what form and purpose they are used for. Audi thus, its batteries; It provides a sustainable development by evaluating its two lifetimes, one in the car and the other in electricity storage. It is extremely important to evaluate the second life of the batteries in terms of both cost and eliminating the carbon emissions that occur during the production of new batteries.

In the project, RWE has built 160 square meters of space for 60 battery modules weighing around 700 kilograms at the power plant site in Herdecke. The assembly of the battery systems in the area was completed in October. Individual components were also commissioned in November. RWE will use stored second-life batteries primarily to supplement the power grid as part of periodic maintenance. The company will also implement pilot projects for different areas of use in the future.
Saying that the storage of powerful batteries plays an extremely important role in the energy revolution, Roger Miesen, CEO of RWE Generation; “Flexible storage technologies are needed to compensate for short-term fluctuations in renewable energy and stabilize the grid. Battery storage systems are ideal for this purpose. At Herdecke together with Audi, we use end-of-life high-voltage batteries for electric cars. We test how it behaves like stationary energy storage devices when connected to each other. The continued use of this type of ‘second life’ storage is a sustainable alternative to new batteries. The experience we gained from this project will help us determine the applications where we can use such battery systems most efficiently.” he stated.
