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.
