The invention refers to a method for operating a battery system (10), comprising a battery unit (40) with several battery modules (50) and a starter battery (20) for heating the battery modules (50) of the battery unit (40), whereat a group of battery modules (50) to be heated initially is selected; the selected group of battery modules (50) is heated initially via the starter battery (20) until the selected group of battery modules (50) has reached a predetermined first temperature level; and the remaining battery modules (50) are heated until all battery modules (50) have reached a predetermined second temperature level. The invention also refers to a battery system (10), comprising a battery unit (40) with several battery modules (50), a starter battery (20) for heating the battery modules (50) of the battery unit (40) and a control unit (60) for controlling and supervising the battery unit (40) and the starter battery (20). The control unit (60) comprises a managing unit (62) that is designed to execute the method according to the invention.
