Inductive power transfer device and system for inductively charging a water-bound vehicle and method for operating an inductive power transfer device

A method for operating an inductive power transfer device, the device being configured for an inductive power transfer to a water-bound vehicle, wherein the inductive power transfer device comprises:

• a power transfer part, comprising a primary conductor arrangement;
• and
• a kinematic unit for enabling a movement of the power transfer part;
• wherein the kinematic unit comprises a linear guide;
• and
• wherein the kinematic unit further comprises a foldable arm that allows for a movement of the power transfer part along at least one horizontal spatial axis (X, Y), wherein the foldable arm comprises at least two rotational joints which are spaced apart from another;
• wherein the linear guide comprises an elongated guiding member and at least one displaceable member which is displaceable along said guiding member, and
• wherein the inductive power transfer device further comprises a floatable member that is configured to float on a body of water, wherein said floating member is coupled to the displaceable member,
• wherein the method comprises the step of:
• moving the power transfer part along a path defined by the linear guide, thereby altering a position of the power transfer part along a vertical spatial axis (Z);
• and is further characterized by the step of:
• altering a position of the power transfer part along the horizontal spatial axis (X, Y) by folding or unfolding the foldable arm of the kinematic unit.
