What is serial hybrid propulsion?

BARTALI is a WIDER 150 that’s equipped with a serial hybrid propulsion system and azimuthal thrusters.

This smart system controls and manages the electric power generated by the four generators and stored in batteries. The power produced runs the yacht and all the hotel functions bringing about many advantages, from greatly reduced consumption to increased cruising range.

The yacht’s traditional engine room has been replaced by two separate units: the Power Generator Room in the bow and the Technical Room in the stern where the lithium polymer (LiPo) batteries are housed. This frees up one of the largest parts of the hull, so more spacious guest cabins can be positioned in the most stable zone of the yacht.

The propulsion system is completely modular: the BARTALI can be run exclusively by the batteries in Zero Emission Mode (ZEM) or by activating up to four in-line diesel generators. All the on-board power sources are controlled by the Power Management System (PMS), a smart system that is fully integrated with the yacht that handles the power coming from shore, the generators and the battery packs. The PMS then distributes the power to the hotel functions, the propulsion system and the battery recharge system as required. The partner for this project is Nidec Industrial Solutions, a market leader as well as supplier of the entire PMS.

BARTALI offers 14 knots at maximum speed. At a cruising speed of 13 knots, the yacht has a range of 2,500 nautical miles or alternatively up to 4,700 at an eco-speed of 10 knots.
BARTALI can run purely on her batteries in Zero Emission Mode, with silent cruising at a speed of 5 knots. This is the ideal setup for short trips or in order to cast off early in the morning ensuring the utmost quiet with no generators needing to be started.

The benefits:

+ Greater reliability

+ Fuel efficiency

+ Higher navigation range

+ Noise and vibration reduction

+ Greater flexibility

+ Reduced environmental impact
