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.

Abstract: A drive system for a plug-in hybrid motor vehicle, having an internal combustion engine, an electric motor, a high-voltage source, in particular a high-voltage battery which has a minimum setpoint state of charge, a generator, a clutch, at least one transmission, at least one drive axle and a control unit, with the internal combustion engine being mechanically connected to at least one drive axle, with a first drive mode, “depleting mode”, and a second drive mode, “sustaining mode”, being provided in the control unit, with a third drive mode, “increasing mode”, which can be manually activated being provided, said third drive mode providing a load point increase at the internal combustion engine in such a way that the high-voltage source can be charged during driving and therefore the first drive mode can be activated.
