PROBLEM TO BE SOLVED: To provide a device for the contactless charging of an electrical energy storage means of a motor vehicle.SOLUTION: The present invention relates to a device (1) for the contactless charging of an electrical energy storage means (2) of a motor vehicle, the device including at least one primary coil (3) which may be connected to an electrical power supply system and a bottom housing (4) in which the primary coil (3) is arranged. The device (1) is formed so that alternating current can be flown in the primary coil (3) during operation and the primary coil can generate an alternating magnetic field (10). The alternating magnetic field (10) can induce an alternating voltage in a secondary coil (6) on a vehicle side, the secondary coil being separated from the primary coil (3) by an air gap. As a result, current that is variable with time is caused. The current is converted by a rectifier means provided on the vehicle side into a direct current so that the electrical energy storage means connected to the rectifier means can be charged. The at least one primary coil (3) is connected to the bottom housing (4) in such a way to move mechanically under the effect of an external compressive force.SELECTED DRAWING: Figure 2 |
