Vessel with electric power connectors
A vessel includes electric connectors for receiving one or more direct voltages from a shore-side electric power system. The vessel includes a transmitter for transmitting, to the shore-side electric power system, a control signal enabling the shore-side electric power system to control the one or more direct voltages to be suitable for the vessel. Alternatively, the vessel includes one or more controllable direct voltage converters and a control system for controlling the one or more controllable direct voltage converters to convert the one or more direct voltages into one or more direct voltages suitable for the vessel. The vessel can be for example a ship, a boat, or a ferry.
1. A vessel comprising:
electric connectors configured to receive direct voltages from a shore-side electric power system, the direct voltages being different from each other;
controllable direct voltage converters; and
a control system configured to control the controllable direct voltage converters to convert the received direct voltages into one direct voltage suitable for the vessel.
2. The vessel according to claim 1 , further comprising a chargeable battery system configured to receive charging energy from the electric connectors of the vessel and configured to supply electric power to a propulsion system of the vessel.
