Abstract (en)
[origin: WO2012136357A2] The invention relates to a device and to a method for checking the leak-tightness of an electrochemical energy accumulator, which is formed as an individual battery cell (2) or as a battery (1) having a plurality of individual battery cells (2) connected to one another in parallel and/or in series, wherein at least one detector unit (4) is provided, by means of which a gas concentration in a housing can be detected. According to the invention the housing is designed as a battery housing (3) and can be closed, wherein the detector unit (4) is a metal oxide sensor that is connected to an evaluation unit (5), and, depending on the detected gas concentration, a control signal can be generated automatically by means of the evaluation unit (5) for switching off the electrochemical energy accumulator and/or for triggering a binder release unit (6).
