What They Do
NAEXT GmbH is a German cleantech company based in Seevetal, founded in 2019, initially focusing on vehicle electrification. The company developed electric conversion kits that enable combustion engine vehicles to be converted into electric vehicles in less than a week, targeting workshops and fleet operators (source: naext.de, erneuerbare-energien-hamburg.de). Alongside this, NAEXT has established a second business division for modular battery storage systems, primarily designed for commercial, industrial, and solar applications. Their products HEXAGON and QUADRAGON offer flexible capacities ranging from 54 kWh up to 8 MWh and are based on second-life batteries, emphasizing circular economy and sustainable raw material use (source: seevetal-aktuell.de, topagrar.com). NAEXT thus combines vehicle conversion and stationary energy storage with a strong focus on European supply chains and sustainable technologies (source: erneuerbare-energien-hamburg.de).
Projects & Track Record
NAEXT has distinguished itself by developing a production-ready electric drivetrain for VW T5 and T6 Transporters, delivering 110 kW of power. Conversion costs start at 28,000 euros, and battery capacity can be expanded in 18 kWh increments up to 90 kWh. The company also plans to include additional vehicle models such as the Audi A2 in its portfolio and collaborates with workshops nationwide (source: autobild.de). In the stationary energy storage sector, NAEXT partnered with Enerparc to develop battery storage systems for ground-mounted solar parks, primarily to compensate for nighttime power generation. Since 2021, the company has focused on further developing and marketing these storage solutions (source: vision-mobility.de). Customers include well-known companies such as Otto Dörner, SPIE, Viebrockhaus, and MEA, operating in construction, services, and industry sectors (source: seevetal-aktuell.de).
Recent Developments
Over the past two years, NAEXT has expanded its product range in battery storage and increased its market presence. In September 2026, an environmental working group from the CDU visited the company in Beckedorf and received a technical presentation on the modular storage solutions HEXAGON and QUADRAGON (source: seevetal-aktuell.de). Additionally, in 2025, a detailed product brochure for the QUADRAGON storage system was published, outlining a 10-year specification for use in solar parks and commercial applications (source: topagrar.com).
