encore | DB extending battery life

Lithium-ion batteries are considered a key technology in electric mobility, yet they lose storage capacity over the course of their lifetime. After eight to ten years, the battery's performance drops to below 80 per cent and is therefore often replaced.

We take used batteries from manufacturers and authorised dealers of e-vehicles across Europe and use them to produce modular second life battery energy storage systems. Batteries whose performance is no longer sufficient for a second life are sorted out and passed on for professional recycling.

The second life of a battery not only improves the CO2 footprint of electric mobility, but it also supports the decarbonisation of energy by providing sustainable battery energy storage systems, which are particularly needed in times of volatile renewable energy.

Every battery module that is installed in our second life battery energy storage systems is subjected to intensive testing. In this way, we ensure that only battery modules that meet the highest standards of safety, quality and performance are used.

By using raw materials that are already in circulation, our second life battery energy storage systems are more sustainable than battery energy storages with new battery modules. By using second life battery energy storage systems, we can save 6 tons of CO₂ emissions in the production of a 65-kWh battery storage in direct comparison with new battery energy storage systems.

Our second life battery energy storage systems are more financially economical when compared to battery energy storage systems made with new battery modules - an important advantage for our customers. The modular design also offers a high degree of flexibility for different application possibilities and sizes in the profession. This means that the energy storage systems can be individually adapted to the respective needs and can also be expanded later.
