Recycled Electric Car Batteries Now Offered for Energy Storage by Moon Power

Porsche Holding Salzburg, a subsidiary of the automotive group, has presented a groundbreaking modular energy storage solution named RE:LIFE. This innovative system, developed in collaboration with Pramac and B-ON, offers a resource-efficient and cost-effective alternative to conventional storage systems.

The RE:LIFE project was initiated in 2023, with a focus on sustainability and efficiency. The system is designed for use with Volkswagen's Modular Electric Car Kit (MEB), specifically utilising 60 NMC traction batteries from the MEB platform, which, after use in a vehicle, typically retain more than 70% of their original energy capacity. This residual capacity offers potential for a second life, such as in stationary energy storage.

The RE:LIFE energy storage system, equipped with two inverters that together provide 176 kVA of AC power, was installed at MoonCity Salzburg in December 2024. The prototype was placed in a prototype test stand, with two storage units, each containing 30 slots.

The RE:LIFE energy storage system has been used for self-consumption optimization, peak shaving, and intermediate storage of photovoltaic energy. Pramac developed and produced the modular cabinet system and handled the technical adaptations to the high-voltage batteries. B-ON, on the other hand, provided the battery management system and ensured reliable communication within the storage modules.

The project team paid particular attention to safe installation, including enhanced high-voltage protection for safe battery replacement. The RE:LIFE prototype is now entering production after successful prototype testing. Porsche Holding Salzburg management gave the green light for the next phase of the project in summer 2025, planning the production of a small series for selected pilot sites.

However, the specific locations for the small series production of the RE:LIFE energy storage systems, where later testing is also intended, are not explicitly mentioned in the provided search results.

Konstantin Pache, project leader for technology and innovation projects at Moon Power, commented that RE:LIFE demonstrates how modern technology and sustainable thinking can go hand in hand without compromising efficiency or safety. This approach avoids valuable electronic waste and significantly reduces production costs, making it a promising solution for the future of sustainable energy storage.
