A method for operating a motor vehicle. A map of corresponding event locations for one or more high load events is provided, wherein the one or more high load events have historically led to an above-average load on a vehicle component. A current position and/or route of the motor vehicle is determined. A high load event is identified from among the one or more high load events as likely to be relevant to the motor vehicle during the current operation. The identification of the high load event is based on the current position and/or route of the motor vehicle. The vehicle component is thermally preconditioned, via a corresponding automatic control of at least one device of the motor vehicle, before the motor vehicle has reached the corresponding event location of the identified high load event.

Method for operating a motor vehicle, and motor vehicle

An air-conditioning system for an electrified motor vehicle with an interior and a high-voltage accumulator, includes an air-conditioning installation and an electronic control unit. The air-conditioning installation air-conditions both the interior and the high-voltage accumulator. The control unit implements a preconditioning mode during charging of the parked vehicle before a journey begins in such a way that: (a) at least the length of the route and the outside temperature over the length of the route can be predicted, and (b) in that, depending on the prediction, the high-voltage accumulator can be used as: (i) a heat accumulator, when the predicted outside temperature over the length of the route is lower than the heating threshold target temperature required by the high-voltage accumulator, or (ii) a cold accumulator, when the predicted outside temperature over the length of the route is greater than the heating threshold target temperature required by the high-voltage accumulator.

Temperature-control system and method for the temperature control of an electrified motor vehicle

A method for temperature control of a traction battery includes predefining a target temperature which the traction battery should have at the end of a journey and upon arrival at a fast-charging station; predicting a temperature which the traction battery will have at the end of the journey and upon arrival at the fast-charging station; determining a temperature difference between the target temperature and the predicted temperature; predefining a temperature control specification for temperature control of the traction battery during the journey of the motor vehicle to the fast-charging station in accordance with the determined temperature difference, so that the target temperature prevails upon arrival at the fast-charging station; and controlling the temperature of the traction battery according to the predetermined temperature control specification during the journey of the vehicle.
