A method of warming a traction battery (120) of a vehicle. The vehicle comprises an inverter (130), a cooling circuit (250) by which the traction battery (120) and the inverter (130) are thermally coupled with one another, and an electric machine (140). The inverter (130) receives direct current from the traction battery (120) and converts the direct current into an alternating current which is supplied to the electric machine (140). The method includes a step in which a reactive current fraction of the alternating current is set in such manner that waste heat is produced in the inverter (130) for warming the traction battery (120) by way of the cooling circuit (250). |
