Arrangement For Pressure Monitoring Within A Battery Housing, Battery Management Device, And Battery System With An Arrangement

An arrangement for pressure monitoring within a battery housing of a battery system. The arrangement includes a first power supply path and a pressure measuring. The pressure measuring unit is electrically connected to the first power supply path. The arrangement also includes a pressure-sensitive mechanical switching unit arranged within the battery housing and electrically connected, in series with the pressure measuring unit, to the first power supply path. The switching unit switches to an electrically conductive switching state when the pressure within the battery housing exceeds a predefined pressure threshold and establishes a supply of power to the pressure measuring unit via the first power supply path, and switches to an electrically blocking switching state when the pressure within the battery housing falls below the pressure threshold and interrupts the supply of power to the pressure measuring unit via the first power supply path.
