  • Patent number: 10978764
    Abstract: A battery air dryer for drying air within a battery housing of an electric vehicle battery has a support structure for dryer material. The support structure has a first fixing element coupling with a first coupling element of the battery housing and a second fixing element coupling with a second coupling element of the battery housing. The first and second fixing elements are arranged on different sides of the support structure such that a first distance between the first fixing element and a reference plane differs from a second distance between the second fixing element and the reference plane. The reference plane is a plane cutting the support structure horizontally when the battery air dryer is mounted in the battery housing in a designated orientation. Only the first fixing element or only the second fixing element is arranged in a first fixing plane parallel to the reference plane.
