How second life battery energy storage systems promote the circular economy and drive the energy transition.

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.

The encore team takes used batteries from manufacturers and authorised dealers of e-vehicles throughout Europe and uses the logistics network of Deutsche Bahn for transport. The batteries are then dismantled from battery pack to battery module level and subjected to a safety and quality analysis as well as tested for remaining capacity. Battery modules that are unsuitable for a second life are sorted out and sent to be professionally recycled. Battery modules with sufficient remaining capacity are reused for the production of second life battery energy storage systems.

The second life of a battery not only improves the CO2e 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.

Use cases:

  • Self-consumption optimisation
  • Peak shaving
  • Power supply
  • Grid stabilisation
  • Buffered charging
