Abstract

A method for diagnosis of a temperature control means (30) of a battery pack (10) that comprises a plurality of battery cells (20) and a plurality of temperature sensors for measuring temperatures of the individual battery cells (20), the battery cells (20) being arranged side by side in the battery pack (10), in a longitudinal direction (12) of the battery pack (10), and mechanically connected to each another, and the battery cells (20) being arranged on the temperature control means (30) and mechanically and thermally connected to it. A battery management system, and/or a battery pack (10) may be configured to execute the method. A vehicle may be fitted with a battery pack that carries out the method.
