A device for inductively transmitting electrical energy between a power supply unit arranged on the shore of a body of water or in the body of water and a watercraft includes a primary coil associated with the power supply unit, and a secondary coil which is connectable to the primary coil for inductively transmitting electrical energy, and which is arrangeable on the watercraft. A height-adjustment device connected to the primary coil is provided in order to hold the primary coil at a consistent vertical distance from a water surface in a vertical direction running in the direction of the buoyancy. A corresponding charging system and method includes: aligning the coils relative to one another; previously or simultaneously adjusting a vertical distance between the primary coil and water surface by with a height-adjustment device; inductively transmitting electrical energy between the coils.
A device for inductively transmitting electrical energy between a power supply unit arranged on a shore of a body of water or in the body of water and a watercraft that is movable relative to the shore, the device comprising at least one primary coil associated with the power supply unit and arrangeable on or in the body of water, at least one secondary coil arrangeable on the watercraft and operatively connectable to the at least one primary coil for inductively transmitting electrical energy, a height adjustment device connected to the at least one primary coil and configured for maintaining the at least one primary coil at a constant vertical distance from a water surface in a height direction extending in a direction of buoyancy, and an inclination adjustment device configured for adjusting inclination of the at least one primary coil.
