Abstract
A device for inductive transfer of electric energy from a stationary unit including at least one primary inductance to a vehicle that is adjacent to the unit and has at least one secondary inductance. The stationary unit has a device for detecting the presence of an electrically conductive object in a predetermined area that borders the primary inductance. The area can be between the primary and secondary inductance during the inductive energy transfer. The device has at least one measuring inductance, a measuring unit for measuring the impedance of the measuring inductance and an evaluation unit connected to the measuring unit. Preferably, the device is equipped with a plurality of measuring inductances which form a regular two-dimensional arrangement extending approximately in one plane, the plane lying perpendicular to the main direction of the magnetic field that is generated by the primary inductance during operation.
