Method for determining a temperature distribution along a battery, observation device and battery

摘要

The invention relates to a method for determining an actual temperature distribution along a battery (10), which comprises a plurality of battery cells (14) electrically interconnected to form a cell assembly (12) and thermally coupled to one another, wherein for a respective battery cell (14) of the battery (10) a temperature sensor (16) for detecting temperature values (34) is provided at a measuring position (18) assigned to the respective battery cell (14), with the aid of a current and / or a respective past temperature value (34) an actual cell temperature value (40) at a fictitious measuring position (23) of the respective battery cell (14) different from the measuring position (18) is estimated according to a predetermined estimation rule (30), the estimation rule (30) at least one of an installation position of the respective battery cell ( 14) within the cell network (12) dependent thermal influence pa parameters are taken into account when estimating the actual cell temperature value (40), the actual temperature distribution along the battery (10) being determined based on the respective actual cell temperature values (40) of the plurality of battery cells (14).
