Technical Brief: 400V Electric Ferry Retrofit
The Engineering Challenge
A commercial ferry operator mandated a complete diesel-to-electric conversion. The powertrain required a stable 400V DC bus to supply a 150kW electric propulsion motor. The primary constraint was the highly restricted physical footprint of the existing engine room.
The CLF Solution & Results
We engineered a highly compact energy storage system utilizing 8 units of our CLF-51280 modules connected in series. This created a seamless 409.6V, 114.7kWh power bank.
✓ Space Optimized: Reduced installation footprint by 40%.
✓ Operational Efficiency: Sustained 6 hours of continuous cruising operation per charge.
✓ Compliance: Zero emissions achieved, meeting strict local waterway tourism regulations.
