Embodiment Construction

[0027] The single FIGURE shows an energy absorption device 1 for an electrically operable motor vehicle 11 , which is now shown only schematically with dashed lines in the drawing. The energy absorption device 1 comprises an induction coil 2 which can apply an electromagnetic field to an outer induction coil 3 for charging an energy store 4 of a motor vehicle 11 . Energy store 4 is designed, for example, as a so-called high-voltage battery, which is energy-transmittingly coupled to induction coil 2 . The coupling between the energy store 4 and the induction coil 2 will not be described further in the present. The induction coil 2 , also referred to as the secondary coil, is arranged on the underbody 17 of the motor vehicle 11 in an absorption region 10 formed by the shielding device 5 consisting of the first shielding part 6 and the second shielding part 7 .

[0028]The shielding device 5 consisting of the first shielding part 6 and the second shielding part 7 is designed as ...

Abstract

The invention relates to an energy absorption device (1) for an electrically operable motor vehicle (11), which has an induction coil (2) designed for an energy store (4) of the motor vehicle (11) ) to load. The energy absorption device (1) includes a shielding device, by means of which the induction coil (2) can be shielded from the motor vehicle (11). The shielding device (5) has at least one first shielding component (6) separating the induction coil (2) from the motor vehicle (11) in the vehicle transverse direction (13) and / or in the vehicle longitudinal direction (14) and at least one A second shielding component (7) separating the induction coil (2) from the motor vehicle (11) upward in the vehicle height direction (12) is connected to the first shielding component (6). The invention also relates to a method for operating the energy absorption device (1) of an electrically operable motor vehicle (11).

Description

technical field [0001] The invention relates to an energy absorption device for an electrically operable motor vehicle, which has an induction coil which is designed to load an energy store of the motor vehicle. Furthermore, the invention relates to a method for operating the energy absorption device for an electrically operable motor vehicle. Background technique [0002] For such an energy absorption device, an electromagnetic field is applied to the induction coil (secondary coil) by means of an external induction coil (primary coil). In this application, the internal energy store of the motor vehicle is acted upon by means of the self-varying magnetic field of the external induction coil. The energy store can be designed, for example, as a so-called high-voltage battery. In contrast to refueling with fossil fuels (eg LPG, CNG, petrol or diesel), contactless energy storage is achieved in inductive loading, wherein monitoring by the driver or the refueling personnel is n...
