A method for operating a traction battery in a motor vehicle, wherein the traction battery is charged in a charging operating state with a fast-charging device. A quantity of energy to be recharged at the fast-charging device is specified. An anticipated heating of the traction battery is determined depending on a charging capacity, which, taking into consideration a predeterminable maximum charging time, is determined from the quantity of energy that is to be recharged. A starting temperature (Tstart) for the battery charging is determined in such a way that, after the charging operation has been carried out at the fast-charging device, a battery operating temperature (Tbatt) of the traction battery does not exceed an upper limit (Thi) for the battery operating temperature. The battery operating temperature (Tbatt) is recorded during a driving operating state of the motor vehicle.
