Method and device for controlling a battery pulse heating mode of a traction battery of a hybrid vehicle

A device for controlling a battery pulse heating mode of a traction battery of a hybrid vehicle that has an internal combustion engine and an electric machine, comprising:

• a temperature detector for detecting a traction battery temperature of the hybrid vehicle after the hybrid vehicle has been started;
• a start state detector for detecting a start state of the hybrid vehicle;
• a determining device for determining a distance that must be traveled for a battery pulse heating mode to result in reduced fuel consumption of the internal combustion engine for at least one predefined road type at the detected traction battery temperature;
• a display device for displaying the determined distance;
• an input device for selecting whether the battery pulse heating mode should be carried out;
• and
• a control device for controlling the battery pulse heating mode as a function of a control signal that can be generated on the basis of an input at the input device.
