Abstract

Method for detecting an opening in a housing (250) of a battery module (100) comprising the steps • Detection (310) of a first measurement quantity by means of a first sensor (260), wherein the detected first measurement quantity represents a detected opening of the housing (250), • Detection (315) of a further measured quantity by means of a further sensor (270), wherein the detected further measured quantity represents the opening of the housing (250), • Generation (320) of a first sensor signal using the first sensor (260) depending on the detected first measured quantity, • Generation (325) of a further sensor signal by means of the further sensor (270) depending on the further measured quantity acquired, and • Activation (330) of a battery management system (200) depending on the first sensor signal, • Generation (340) of a locking signal depending on the first sensor signal of the first sensor (260) and additionally depending on the further sensor signal by means of the battery management system (200), and • Deactivation (350) of the Battery Management System (200) depending on the generated locking signal.
