A device (1) for contactless charging of an electrical energy storage (2) of a motor vehicle that has a height adjustable chassis. A primary coil (3) is arranged in a bottom housing (4) on a surface on which the motor vehicle will be parked. The primary coil (3) is connected to an electrical power supply and will induce an alternating electrical voltage in a secondary coil (6) on the vehicle for charging the electrical energy storage (2). The primary coil (3) is connected to the bottom housing (4) by a spring (8, 9) that will compress under the effect of an external compressive force that may occur if the chassis is adjusted too low, thereby avoiding damage to either of the coils (3, 6).
