Marine electric propulsion systems>>

The marine electric propulsion system is powered by a generator set and/or power battery pack, which provide electrical energy to the AC or DC bus, which is distributed through the bus and then transmitted to the propulsion motor or the ship's daily power grid.

Advantages of marine electric propulsion systems:

Save fuel expenses;

Reduce equipment noise and vibration;

Save cable and construction costs;

Reduce emissions of pollutants such as COx and NOx;

Increase the safety and surplus of the ship's electric power system;

Simple and convenient new energy interfaces, such as lithium batteries and solar energy.
