Abstract

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.
