A rechargeable battery assembly for a vehicle has a metal-air rechargeable battery and a filter device to condition inlet air supplied to the metal-air rechargeable battery such that the inlet air exhibits predetermined inlet air values. The filter device has one or more filter elements, one or more sensor devices that determine at least one inlet air parameter, and one or more valve devices. A control system is coupled to the sensor devices so as to receive sensor signals for the at least one inlet air parameter and is coupled to the valve devices. The control system adjusts, depending on the received sensor signals, the valve devices in order to control the predetermined inlet air value in that the inlet air is guided through the filter elements; is guided past the filter elements; or is guided to an air outlet for regenerating the filter elements.

Rechargeable battery assembly for a vehicle

A rechargeable battery assembly for a vehicle has a housing and at least one metal-air rechargeable battery arranged in the housing. A filter device is arranged in the housing and conditions the inlet air of the at least one metal-air rechargeable battery such that the inlet air exhibits a predetermined air humidity. A flow deflecting device is provided that deflects the inlet air in the housing such that the filter device can be regenerated by waste heat of the at least one metal-air rechargeable battery.

A sound damping device () for a tubular duct (), particularly a gas transporting tract of an internal combustion engine () having a least one bypass channel () running parallel to a main duct () in a section of the duct (). The bypass channel () is longer than the main duct () between a branching off point () and a re-entry inlet (). The bypass duct according to the invention is configured as a spiral duct () which winds around the centrally disposed main duct () in order to decrease the installation space requirements for the noise suppressor ().
