Voltfang develops high-performance European battery storage systems built from requalified EV batteries for industrial, commercial and grid-scale customers. Its core product pairs energy-dense battery modules with an intelligent energy management system, Venma, which uses AI to maximise self-consumption, lower electricity costs and enable participation in energy markets. Customers include Aldi Nord, Alba Group, Fiege Logistik and Goldbeck. The company opened the "Voltfang Future Fab" in Aachen to scale production and enable capacity up to 1 GWh, and aims to deliver an additional 250 MWh of storage across Europe by the end of 2026. Storage capacity grew from 5 MWh in 2023 to 20 MWh in 2024, and Voltfang targets supporting the replacement of the Weisweiler coal-fired power plant by 2030. By using second-life and surplus batteries sourced from the European automotive industry, the company seeks to reduce reliance on Asian supply chains and foster a resilient European battery industry. Voltfang develops green energy storage systems built using requalified electric vehicle batteries, pairing hardware with an advanced Energy Management System. The company aims to broaden its product offerings and invest further in its EMS to maximize battery performance. Voltfang targets commercial/industrial and grid-scale applications and emphasizes circular-economy principles and reuse/second-life concepts. Management plans to deploy an additional 40 MWh of battery capacity by 2025. The company recently completed an oversubscribed financing round, which it closed within three months, strengthening its growth outlook and market position in sustainable energy infrastructure. Voltfang, based in Aachen, builds stationary energy storage systems from used electric vehicle batteries and uses AI-based software to evaluate battery longevity. Its operating system and continuous monitoring aim to make second-life batteries as durable as new ones, backed by a 10-year "Batteryflat" guarantee. The company has completed successful pilot projects in Germany and lists Aldi NORD and Schaltbau among its clients. Voltfang says the systems can be intelligently deployed to amortise batteries quickly and support grid stability amid rising electrification. Management highlights the ability to connect urgently needed capacity to the grid to help avoid blackouts. The company has raised €5 million to scale its production.
