Since 2015, we have been developing and series-producing high-voltage battery housings and complete traction battery systems. For marine applications, we offer modular battery systems designed to meet specific requirements of electrified and hybrid vessels – from performance and durability to safety and integration.
Our engineering expertise spans simulation, validation, and thermal management, ensuring reliable operation under harsh environmental conditions. With a clear focus on industrial scalability, we support our customers from concept to series production. Advanced manufacturing technologies, including laser and electron beam welding, continuous weld monitoring, and helium leak testing, ensure consistent quality and compliance with highest safety standards – enabling the transition toward zero-emission marine mobility.
