Parallel Hybrid with Integrated Electromagnetic Clutch + Serial Hybrid for Yachts/Vessels 40-250 ft

Summary

The video presents e-Motion Hybrid Systems’ parallel and serial hybrid propulsion systems for vessels.

Parallel Hybrid

Intended for planing hulls, the parallel system couples electric motors to the main diesel engines through an integrated clutch. It also includes variable-speed generators, lithium-ion batteries, and a DC bus.

• Full-electric mode: The clutch disengages, and the batteries power the electric motors and onboard hotel loads.
• Diesel-electric mode: With the clutch disengaged, variable-speed generators supply the DC bus, powering the motors and hotel loads while slowly charging the batteries.
• Alternator mode: While the diesel engines warm up, the clutch engages and the electric motors act as generators, quickly charging the batteries and supplying hotel loads.
• Booster mode: With the clutch engaged, generator power supports hotel loads and battery charging while adding power to the electric motors for higher cruising speed.

Serial Hybrid

The serial system is presented as suitable for displacement and semi-displacement vessels. Unlike the parallel setup, it omits the main propulsion diesel engines and integrated clutch, using additional electric motors and a shaft instead.

• Full-electric mode: Batteries power propulsion and hotel loads, with zero emissions during operation in this mode.
• Diesel-electric mode: Variable-speed generators power propulsion and hotel loads while slowly charging the batteries.
