Abstract (en)
[origin: WO2021116180A1] The invention relates to a pressure relief device for carrying out a pressure relief function for a cell-like cavity (5) which is enclosed by a battery housing (1), comprising a pressure relief cover unit (2) that is inserted or can be inserted into a housing wall (10) and opens a flow path (13) from the cavity into an outer region (4) of the housing (1) when a pressure threshold and/or temperature threshold in particular is exceeded. A reliable function is supported in that the pressure relief cover unit (2) is directly or indirectly connected to a sensor device (6) which comprises at least one sensor element (60) and which is involved or can be involved in a pressure relief monitoring process and/or the pressure relief function in particular.
