Freudenberg e-Power Systems (FEPS) has announced the launch of XWAVE, a modular, stackable battery system designed specifically for maritime applications. The new solution, aimed at both battery-electric and hybrid-electric vessels, will be available starting in 2027, the company said in a statement.
The XWAVE system is based on nickel-dominant Gen 3 SHP mid-nickel single-crystal power cells developed in-house. These cells are engineered for high charging and discharging performance, with a focus on energy density and service life. According to FEPS, the system’s flexible design and integrated telematics will allow shipbuilders and system integrators to adapt power configurations to suit individual vessel requirements.
Each XWAVE module delivers 17 kWh with a nominal voltage of 132 volts. Modules can be connected in series up to a total system voltage of 1,048 volts, allowing for a scalable approach based on available space and energy demands. The design allows for independent scaling of both the voltage and vertical height of the battery installation. A battery disconnect unit (BDU) and battery management system are also included, with remote monitoring possible through telematics integration.
“XWAVE was developed with our customers in mind, who told us they need a battery system with a more flexible design, and ample energy to power everything from ferries to cargo ships,” said Lisa McKenzie, President and General Manager of Battery Systems at Freudenberg e-Power Systems. “This new system builds on our proven track record powering vessels in the maritime market while adapting to the changing needs of the industry.”
FEPS currently supplies energy systems for more than 30 hybrid or fully electric vessels worldwide. The new XWAVE offering is expected to extend the company’s reach in the maritime sector, where demand for zero-emission solutions is growing amid stricter environmental regulations.
Freudenberg e-Power Systems employs around 800 people and is part of the Freudenberg Group, which reported €11.9 billion in revenue in 2024 across its industrial, household, and specialty divisions.
