A battery housing for a traction battery may include a first housing part and a second housing part fixed removably to each other. Battery modules of the traction battery may be fixable on the first housing part. The housing may also include a reinforcing structure having a plurality of reinforcing ribs reinforcing the first housing part, and a ducted structure with a plurality of coolant ducts for a coolant fixed on the first housing part. The plurality of coolant ducts may each be connectable to a respective temperature-control unit of a battery module in a coolant-conducting fashion. At least one of the coolant ducts may be at least partially embedded in one of the reinforcing ribs.

Battery housing for a traction battery

A battery module for a traction battery may include a module housing through which a coolant is flowable and at least one battery cell stack arranged within an interior space of the module housing. The at least one battery cell stack may include a plurality of battery cells arranged one after another along a stack direction. The plurality of battery cells may be arranged within the module housing such that a coolant flowable through the module housing directly contacts the plurality of battery cells. A locking mechanism may form-fittingly connect the at least one battery cell stack to the module housing via (i) a plurality of housing-side locking points and (ii) a plurality of stack-side locking points.

An accumulator assembly for an electric or hybrid vehicle may include a housing including a housing upper part and a housing lower part releasably fixed to the housing upper part. The housing upper part may be fixable to a floor panel of the vehicle. The assembly may further include at least one battery module disposed in a receptacle space between the housing upper part and the housing lower part. The at least one battery module may be releasably fixed to the housing upper part.

A flat filter element for filtering a fluid may include a filter body made up of a folded filter material. The filter element may also include a circumferential edge and a side edge running in a circumferential direction along the circumferential edge. The side edge may have at least one strip portion, running along the side edge, with a side strip that may be separate from the filter body and arranged on the filter body. The side edge may also have at least one adhesive portion running along the side edge for sealing the filter body. The at least one adhesive portion may be formed by gluing of least two folds, adjacent along the side edge, in a region of the side edge.

A humidifier block and a method for producing a humidifier block are disclosed. The humidifier block may include a plurality of membranes each having a cavity for passing a through-flow and a jacket surrounding the cavity in a circumferential direction. The jacket may be moisture-permeable. At least one strip-shaped carrier may be fitted with the plurality of membranes, and the plurality of membranes may arranged in a longitudinal direction parallel to one another and adjacent to one another on the at least one carrier. The at least one carrier fitted with the plurality of membranes may be shaped into the humidifier block such that the plurality of membranes are arranged adjacent to one another in a transverse direction running transversely to the longitudinal direction and adjacent in a height direction running transversely to the longitudinal direction and transversely to the transverse direction.

A hydraulic feed device may include a pendulum-slide cell pump having an internal rotor drivingly connected to an external rotor via pendulum slides. A hydraulic positioning device may have a positioning element for changing an eccentricity between the internal rotor and the external rotor. The positioning element may be preloaded by a spring device for setting a maximum eccentricity. The positioning device may have a first pressure adjusting and a second pressure adjusting chamber for adjusting the positioning element. The first pressure adjusting chamber may be permanently hydraulically connected to a pressure side of the pendulum-slide cell pump and configured to hydraulically counteract the spring device. The second pressure adjusting chamber may be controlled via a control valve and hydraulically connected to the pressure side of the pendulum-slide cell pump and configured to hydraulically counteract the spring device.

Hydraulic feed device and hydraulic system

A filter element for at least one of a fresh air system and a ventilation and/or air-conditioning system of a motor vehicle may include a filter body including a folded filter material that laterally surrounds an internal space. A first end plate and a second end plate may be sealingly attached to the filter body at sides that are facing away from one another. A front plate may be arranged in a lateral region of the filter body. The front plate may include a first end plate joining region and a second end plate joining region facing the first end plate and the second end plate. The first and second end plate joining regions may be fused with a front-side end of the first and second end plates.
