A method for controlling the temperature of a vehicle with at least a partial electric drive while the vehicle is connected to a charging station includes setting up a data link for bidirectional communication between the vehicle and charging station. Vehicle-side data is acquired with vehicle-side means for acquiring data, and charging-station-side data is acquired with charging-station-side means for acquiring data. Optimum temperature control parameters of the battery and passenger cell are determined using a logic by processing the acquired vehicle-side and charging-station-side data. The temperature control of the battery and of the passenger compartment of the vehicle is carried out with temperature control means. A motor vehicle and a charging station carry out the method.
