PRESSURE RELIEF DEVICE, AND BATTERY HOUSING COMPRISING SUCH A PRESSURE RELIEF DEVICE

The invention relates to a pressure relief device for carrying out a pressure relief function for a cell-like cavity () which is enclosed by a battery housing (), comprising a pressure relief cover unit () that is or can be inserted into a housing wall () and opens a flow path () from the cavity into an outer region () of the housing () when in particular a pressure threshold and/or temperature threshold is exceeded. Reliable functioning is supported by the pressure relief cover unit () being directly or indirectly connected to a sensor device () which comprises at least one sensor element () and is or can be involved in particular in a pressure relief monitoring process and/or in the pressure relief function.
