Abstract

A method and a device are provided for controlling a battery pulse heating mode of a traction battery of a hybrid vehicle. The method includes detecting a traction battery temperature (T) upon start-up of the hybrid vehicle. The method then includes determining a dependency of fuel consumption (V) during a battery pulse heating mode on the distance (W) travelled for at least one predefined road type at the detected traction battery temperature (T). The method continues by displaying the determined dependency on a display device (50), using an input device (60) to select whether a battery pulse heating mode should be carried out; and controlling the battery pulse heating mode as a function of the selection.
