Abstract: A method for operating a motor vehicle, in which an electrical energy storage system of the motor vehicle is charged, the system being designed to store electrical energy for a drive assembly of the motor vehicle. At least one electrical heating device of the motor vehicle is supplied thereby with electrical energy from a charging station that is designed to charge the electrical energy storage system. By the at least one electrical heating device, at least one component of a drive train of the motor vehicle is subjected to heat, this component being arranged in the flow of force between the drive assembly and the at least one wheel when driving at least one drivable wheel of the motor vehicle.

Abstract: A component for a motor vehicle, with at least one receiving space for structural elements of the drive component, with at least one first wall that delimits the receiving space at least partially, by way of which at least one collecting region for collecting a lubricant for lubricating the structural elements is delimited at least partially, and with at least one second wall, which is arranged on a side of the first wall that faces away from the collecting region, and which is spaced apart from the first wall at least in a partial region, so that, between the walls, an intermediate space that is delimited at least partially by the walls is formed. For setting a heat transfer coefficient between the walls, a liquid can be introduced into the intermediate space and discharged out of the intermediate space.
