Charging station for motor vehicles and method for operating a charging station
First Claim
Patent Images
1. A charging station for motor vehicles comprising:
- a primary coil for inductive transmission of energy to a battery of a motor vehicle and a metal detector, wherein the metal detector detects a motor vehicle arranged above a charging station surface of the charging station; and
the charging station is provided with a transmitting device, which transmits an occupancy signal if it is detected by the metal detector that a motor vehicle is arranged above the charging station surface, wherein the occupancy signal is transmitted to at least one other motor vehicle indicating that the charging station is occupied; and
an aluminum bottom plate shielding the charging station from the inductive transmission of energy in a downward direction,wherein the primary coil includes the metal detector such that the metal detector is formed for both detecting the motor vehicle on the surface of the charging station and for inducing a voltage in a secondary coil of the motor vehicle.

Abstract
A charging station for motor vehicles, including a primary coil for inductive transmission of energy to a battery of a motor vehicle and a metal detector. The metal detector is designed to detect a motor vehicle arranged above a charging station surface of the charging station. The charging station is provided with a transmitting device which is designed to transmit an occupancy signal if it is detected by the metal detector that a motor vehicle is arranged above the charging station surface.

4. A method for operating a charging station, comprising:
-
detecting by a metal detector whether a motor vehicle is arranged above a charging station surface wherein an occupancy signal is transmitted by a transmitting device of the charging station if it is detected by the metal detector that a motor vehicle is arranged above the charging station surface, wherein a primary coil which charges the motor vehicle includes the metal detector such that the metal detector is formed for both detecting the motor vehicle on the surface of the charging station and for inducing a voltage in a secondary coil of the motor vehicle, and the charging station is shielded in a downward direction, by an aluminum bottom plate, from a magnetic field created by the primary coil and the metal detector. - View Dependent Claims (5, 6)
