DEVICE FOR THE CONTACTLESS CHARGING OF AN ELECTRICAL ENERGY STORAGE MEANS OF A MOTOR VEHICLE
First Claim
1. A device for a contactless charging of an electrical energy storage of a motor vehicle, the motor vehicle further having a secondary coil and a connected to the electrical energy storage, the device comprising:
- a bottom housing external of the motor vehicle;
at least one primary coil arranged in the bottom housing and being connectable to an electrical power supply system so that an alternating current flowing through the primary coil generates an alternating magnetic field that can induce an alternating electrical voltage in the secondary coil on the vehicle and is separated from the primary coil by an air gap, resulting in a current flow that is variable over time and convertible by the rectifier means on the vehicle into a direct current for charging the electrical energy storage connected to the rectifier; and
the at least one primary coil being connected to the bottom housing to yield mechanically in response to an external compressive force.

Abstract
A device (1) for the contactless charging of an electrical energy storage (2) of a motor vehicle has at least one primary coil (3) arranged in a bottom housing (4) and connected to an electrical power supply. The device (1) is formed so that alternating current flowing in the primary coil (3) can generate an alternating magnetic field (10) to induce an alternating electrical voltage in a secondary coil (6) on the vehicle that is separated from the primary coil (3) by an air gap. Thus, a current flow that is variable over time and can be converted by a rectifier means on the vehicle into a direct current for charging the electrical energy storage connected to the rectifier means. The at least one primary coil (3) is connected to the bottom housing (4) in such a way to yield mechanically under the effect of an external compressive force.
