Abstract: An energy supply arrangement for supplying a motor vehicle with electrical energy via a conductive plug connection, includes a stationary charging station and a charging socket which is arranged on board the motor vehicle, the charging station having a charging plug which can be extended in the direction of the motor vehicle. It is provided that the charging plug has a cylindrical base body, on the lateral surface of which multiple electrical contacts are arranged, the base body being encompassed by a protective ring which covers the contacts in a first position and releases the contacts in a second position for contacting counter contacts of the charging socket. A method for operating an energy supply arrangement is also provided.

Abstract: A charging socket for a power supply arrangement for supplying a motor vehicle with electrical energy via a conductive plug connection has at least one electrical mating contact for conductively contacting a contact of a charging station. The electrical mating contact is displaceably mounted with respect to a central longitudinal axis of the charging socket in the radial direction between a first mating contact position and a second mating contact position different from the first mating contact position, wherein the charging socket has an adjusting ring which is mounted rotatably about the central longitudinal axis and has at least one adjustment ramp which, in a first angular position of the adjusting ring, permits a displacement of the electrical mating contact into the first mating contact position and, in a second angular position of the adjusting ring, pushes the electrical mating contact into the second mating contact position.

Abstract: The disclosure relates to a motor vehicle having an electric drive, wherein the motor vehicle has an HV primary energy storage device to supply energy to the electric drive, wherein the motor vehicle has at least one predetermined mounting area, which is formed such that an HV alternative energy storage device can be mounted in the mounting area and the motor vehicle is formed with an access opening through which the HV alternative energy storage device can be placed in the mounting area and through which an HV alternative energy storage device mounted in the mounting area can be removed from the motor vehicle.

Abstract: A train loading system for loading material onto cars of a train is disclosed. The system comprises a material bin arranged to receive material to be loaded onto the train, a closure device arranged to facilitate control by an operator of the amount of material loaded into each car from the material bin, and a car mass estimator arranged to estimate the mass of material loaded into each car. The system also comprises a display arranged to communicate to the operator the estimated mass of material loaded into each car. A corresponding method is also disclosed.

Abstract: A coupling device for producing and separating an energy-transferring plug-in connection, having a plug that can be shifted along a plug-in direction for insertion into a corresponding plug receptacle, and having a drive device, which is operatively connected to the plug for the shifting thereof. In a decoupled state of the coupling device, the plug can be arranged in a position of rest at a tilt with respect to the plug-in direction.
