Abstract
A charging device for inductive transfer of electric energy with a primary conductor arranged in a first housing, by which an alternating magnetic field can be generated when it is energized with an alternating current, electrically connected to a power source that is electrically connectable to a power electronics device for energizing the primary conductor with an alternating current. A drive means for moving the first housing from a first position to a second position, wherein the charging device is equipped with a fault detecting device, by which can be detected whether the first housing is or is not moved when a movement operation has been initiated by the drive means.

A charging device for inductive transmission of electric energy, comprising:
- a primary conductor arranged in a first housing, by which can be produced energizing of an alternating magnetic field with an alternating current,
- a power electronics device, which is electrically connected to a primary conductor and which can be electrically connected to a power supply system with alternating current,
- a drive means for moving the first housing from a first position to a second position, wherein the charging device is provided with a fault detection device, which can be detected whether the first housing is or is not moved when a movement operation has been initiated with the drive means, and which is configured, in the case when a movement of the first housing does not take place, although a movement operation has been initiated with the drive means, to control the power electronic device in such a way that the primary conductor is energized with an electric current to increase the temperature of the primary current.
A method for operating a charging device, comprising:
- providing a charging device,
- detecting by a fault detection device of the charging device whether the first housing is or is not moved when a movement operation has been initiated by the drive means, and
- in case when a movement of the first housing initiated by the drive means has not been detected, controlling the power electronics device with the fault detection device in such a way, that the primary conductor is energized with an electric current in order to increase the temperature of the primary conductor.
