Abstract
A housing for a gas-tight rechargeable battery includes a proportional valve that is arranged at an opening in a housing wall. The proportional valve has a valve body that is influenced by force in the direction of its closed position and towards the interior of the housing. The proportional valve is embodied at least partially from metal such that it allows the through-flow of gas if the pressure that is prevailing in the housing exceeds a construction-dependent pressure limit value. The proportional valve is configured to be connected electrically to the cathode of the rechargeable battery. A contact element embodied at least partially from metal is configured to be connected electrically to the anode of the rechargeable battery and is arranged on the outside of the housing such that the valve body comes into physical contact with the contact element after the proportional valve has achieved a defined open position.
