About KREISEL Electric
Kreisel Electric GmbH is an Austrian technology company based in Rainbach im Mühlkreis, specializing in the development and production of high-voltage battery systems and battery-integrated fast chargers. The company manufactures standardized lithium-ion battery systems based on 21700 round cells with NMC cell chemistry, which are modular and flexibly deployable. The round cells are joined by laser; a core feature is the patented Immersion Cooling Technology, in which the cells are cooled in a thermal management fluid. The battery systems are used primarily in off-highway applications such as construction machinery and agricultural technology, in the marine sector from leisure boats to transport vessels, in charging infrastructure, and in motorsport. The 7,000 m² site comprises a research and development center, a test laboratory, and a fully automated production line. Since December 2021, the company has been part of the John Deere corporate group with over 200 employees; additional planned production sites are located in Saran (France) and Kernersville (USA).
