Abstract

A motor vehicle having a vehicle body, which is formed at least in part from an electrically conductive material. An electrical system is arranged electrically insulated from the vehicle body and has a rectifier unit. An energy coupling device is arranged electrically insulated at the vehicle body for supplying electric energy for the electrical system. The energy coupling device has a coil for wireless magnetic coupling of an energy source that is external to the motor vehicle and provides an alternating magnetic field, wherein the coil is connected to the rectifier unit of the electrical system. An antenna unit is arranged at the vehicle body and is electrically insulated with respect to the electrical system. A decoupling device electromagnetically decouples the coil from the antenna unit.
