Voltfang, established in 2020 as a spin-off from RWTH Aachen University, specializes in creating sustainable energy storage solutions through the repurposing of electric vehicle batteries. The company transforms used EV batteries into efficient storage systems for commercial and industrial applications, contributing significantly to the circular economy in the energy sector. With over 70 employees and 200+ industry partnerships, Voltfang has established itself as a notable player in the renewable energy storage market. The company’s approach not only extends the lifespan of EV batteries but also provides cost-effective storage solutions while reducing the environmental impact of battery production.
Battery Technology
Voltfang’s technology centers on the renovation and repurposing of EV batteries, specifically those utilizing Nickel-Manganese-Cobalt (NMC) chemistry. Their proprietary artificial intelligence-based testing system evaluates each battery’s remaining lifetime and performance capabilities. Batteries meeting strict quality standards are then reconstructed into new battery energy storage systems (BESS).
The company offers two main product lines: the Voltfang 2, designed for small and medium enterprises, and the Voltfang Plus, which supports larger projects with capacities up to 40 MWh. These systems integrate with various energy sources, including solar installations, heat pumps, and charging stations. Each storage solution comes equipped with advanced energy management software and inverters, enabling optimal power distribution and peak load management.
A distinguishing feature of Voltfang’s technology is its 10-year guarantee and comprehensive monitoring system. The company maintains continuous online supervision of all installed systems, ensuring optimal performance and early detection of potential issues. Their energy management system optimizes consumption patterns, reducing energy costs while maintaining reliable power supply.
Recent Projects
In early 2024, Voltfang secured a Series A financing round exceeding €8 million, including €800,000 in grants. This funding supports their ambitious plan to deploy an additional 40 MWh of battery capacity by the end of 2025. The company has also expanded its production capabilities and enhanced its energy management systems to serve a broader range of commercial and industrial clients.
Recent achievements include winning the German Sustainability Award, demonstrating the company’s success in promoting environmental conservation through effective energy storage solutions. Voltfang has also documented numerous successful implementations across various industries, showing significant cost reductions for their clients through efficient energy management.
Investors
Voltfang’s growth is supported by a strong network of investors. The recent Series A round was spearheaded by FORWARD.One and Interzero, with significant participation from existing investors. These include PT1 (PropTech1 Ventures), AENU, Helen Ventures, Daphni, Aurum Impact (the family office of Goldbeck), and Maximilian Viessmann. Earlier funding included a €5 million round in 2023, led by PT1 with participation from Eviny and other strategic investors. This diverse investor base combines expertise in renewable energy, property technology, and sustainable infrastructure.
