Freudenberg e-Power Systems (FEPS) unveiled XWAVE, a versatile, modular battery solution for fully electric and hybrid maritime vessels. Building on over ten years of marine battery expertise, the system combines in-house Gen 3 SHP mid-nickel, single-crystal power cells with an advanced battery management system (BMS) and integrated telematics.
Each XWAVE module delivers 17 kWh at a nominal 132 V and can be connected in series via a battery disconnect unit to reach voltages up to 1,048 V. Modules can be stacked vertically or arranged independently of height, and up to 24 parallel strings may be configured to meet specific power and energy demands. This stackable architecture allows designers and shipyards to customize layouts for new builds or retrofits, optimizing space utilization without sacrificing performance.
The Gen 3 SHP cells are engineered for high charge and discharge rates, competitive energy density, and extended cycle life. The system’s BMS continuously monitors cell and overall system health, while telematics integration provides real-time operational data to support maintenance, streamline servicing tasks, and ensure safe operation within defined limits.
By facilitating emissions reduction and onboard space optimization, XWAVE supports industry efforts to comply with emerging regulations such as the International Maritime Organization’s target of net-zero vessel emissions by 2050. Market analysis from Global Market Insights projects demand for hybrid and fully electric vessels to grow at an annual rate of approximately 24% between 2024 and 2030.
In addition to regulatory compliance, electric propulsion supported by high-performance battery systems enhances the end-user experience through quieter operation, reduced vibration, and minimal disturbance to marine ecosystems.
“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,” says Lisa McKenzie, President and General Manager for 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.”
Freudenberg e-Power Systems, a division of Freudenberg Group, specializes in emission-neutral energy storage and fuel cell systems for heavy-duty applications, offering end-to-end support from development through production, commissioning, and service. FEPS currently powers more than 30 hybrid and electric vessels globally. XWAVE is scheduled to become available in 2027.
