Abstract

A vehicle with an electric drive includes at least one deformation element for protection of pedestrians, which is at least partially formed of a foamed material; at least one secondary transformer unit for electrically charging an energy storage device of the vehicle; and at least one shielding element configured to prevent propagation of electromagnetic radiation emitted from the secondary transformer unit into the vehicle.

Claims

1. A vehicle with an electric drive, comprising

at least one deformation element for protection of pedestrians, which is at least partially formed of a foamed material;

at least one secondary transformer unit for electrically charging an energy storage device of the vehicle via a transformer; and

at least one shielding element formed as a plate and configured to prevent propagation of electromagnetic radiation emitted from the secondary transformer unit into the vehicle,

wherein the deformation element is arranged between the secondary transformer unit and the shielding element.

2. The vehicle of claim 1, wherein

the at least one deformation element is arranged at a front of the vehicle;

the at least one secondary transformer unit is arranged at the front of the vehicle and in front of the deformation element in a direction of travel; and
