Charging device for the inductive transmission of electrical energy and method for operating the charging device
First Claim
1. A charging device for inductive transmission of electric energy, comprising:
- a primary conductor arranged in a first housing, which produces energizing of an alternating magnetic field with an alternating current;
a power electronics device, which is electrically connected to the primary conductor and which is 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 detects 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 a temperature of the primary conductor in that the temperature of the primary conductor is below a predetermined first threshold temperature;
a temperature detection device for detecting the temperature of the primary conductor and of the first housing; and
the fault detection device, which receives the signals of the temperature detection device and which is configured, in the case when a movement of the housing does not take place although a movement operation has been initiated by the drive means, and the temperature of the first hosing is below the pre-determinable first threshold temperature, to exercise control with the power electronics device that is configured to exercise control so that the primary conductor is energized by an electric current in order to increase the temperature of the primary conductor.

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.
