A battery system includes a plurality of battery cells and a temperature-control element that is thermally conductively connected to the battery cells via a temperature-control surface. The temperature-control element has a temperature-control channel in an interior of the temperature-control element. The temperature-control channel is routed on the forward flow side via an inlet and on the return flow side via an outlet from the temperature-control element. A bypass is connected to the temperature-control channel via a dividing node and a merging node with the dividing node being arranged closer to the inlet than the merging node. A motor vehicle includes the battery system.

A temperature control method and a battery system create an optimal temperature range for operating a battery. The battery cells of the battery lie in several separate modules that are integrated in a temperature control circuit. Heat is increased stepwise in a heating phase in which only one first module is heated by means of a temperature control medium, the medium being active in the temperature control circuit and being heated by means of a heating element. The heat that is generated during the operation of at least the first module is used to heat at least one further module.
