1. An arrangement for pressure monitoring within a battery housing of a battery system, the arrangement comprising:
a first power supply path;
a pressure measuring unit for measuring a pressure within the battery housing, the pressure measuring unit is electrically connected to the first power supply path for power supply purposes; and
a pressure-sensitive mechanical switching unit is arranged within the battery housing and is electrically connected, in series with the pressure measuring unit, to the first power supply path via two electrical terminals, wherein:
the pressure-sensitive mechanical switching unit switches to an electrically conductive switching state when the pressure within the battery housing exceeds a predefined pressure threshold establishing a supply of power to the pressure measuring unit via the first power supply path, and
the pressure-sensitive mechanical switching unit switches to an electrically blocking switching state when the pressure within the battery housing falls below the pressure threshold interrupting the supply of power to the pressure measuring unit via the first power supply path.
