Second life for EV batteries: Moon Power launches modular RE:LIFE storage system

Moon Power is focusing on the second-life of batteries that are repurposed for stationary storage system. According to Porsche, following a successful prototype phase, the modular RE:LIFE battery system will now enter small-scale production. It’s intended to reduce electronic waste and lower production costs. Project lead Konstantin Pache emphasizes: "With RE:LIFE, we are showing how modern technology and sustainability go hand in hand—without compromising on efficiency or safety."

Modular system and technical details

The prototype in MoonCity Salzburg consists of two storage units, each with 30 slots. The modules are integrated into the local energy management system and support self-consumption, peak shaving and photovoltaic storage. Two inverters provide a total of 176 kVA of AC power. Sixty NMC traction batteries from the MEB platform provide a gross 411 kWh. The fully air-conditioned outdoor system has a modular design and is controlled by the OptiMoon management system, which allows flexible scaling.

Small-series and pilot projects

Following management approval in the summer of 2025, small-scale production will kick off. The units will be installed and tested at selected sites. Florian Fürtbauer of Porsche Real Estate GmbH explains: "The storage systems increase the self-sufficiency of our sites." RE:LIFE demonstrates how second-life batteries can efficiently support the sustainable energy supply for companies.

Collaborations for high efficiency

Pramac has developed the modular cabinet system and adapted the high-voltage batteries. B-ON supplies the battery management system, while Moon Power coordinates the system architecture, integration, and testing phase. These collaborations supposedly ensure the flexibility, efficiency and reliability of the storage solution.

Conclusion

RE:LIFE demonstrates that used EV batteries can be used as stationary energy storage. The modular system combines flexibility, cost-effectiveness and sustainability, and could be a good example for the energy transition in companies and corporations.
