Abstract: A motor vehicle may include a drive train which has at least one electric machine. The electric machine can be connected or is connected to an electric energy store that can be charged with a charging interface from an external charging device, which electric machine is designed to generate a torque and transmit it to an output of the drive train. A decoupling device may be included, which is designed to mechanically decouple the electric machine from the output, when required, in order to carry out a charging operation in a decoupling state. In the decoupling state, a rotational movement of the rotor of the electric machine into a target charging orientation of the rotor is decoupled from the output of the drive train.
