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 (T) 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 (T) of the traction battery does not exceed an upper limit (T) for the battery operating temperature. The battery operating temperature (T) is recorded during a driving operating state of the motor vehicle.

Method and battery management system for operating a traction battery in a motor vehicle and motor vehicle having such a battery management system

The invention relates to a device for controlling the temperature of an electrical energy store on the motor vehicle side, comprising at least one temperature control system having at least one pettier element, which can be thermally coupled, or is thermally coupled, with the electrical energy store on the motor vehicle side, or to an electrical energy store on the motor vehicle side to be temperature-controlled, wherein in addition, the at least one temperature control system is thermally coupled with at least one temperature-control fluid reservoir containing at least one temperature-control fluid.
