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.

Abstract: A filter element for filtering a fluid is connectable to a filter head with a drainage channel. The filter element has a closure element that closes the drainage channel of the filter head when the filter element is connected to the filter head. The closure element is eccentrically arranged relative to a longitudinal axis of the filter element at an end face of the filter element. The closure element extends away from the end face of the filter element in an axial direction of the filter element. A stand is locked at the filter element and extends away from the end face of the filter element in the axial direction to a level of a free end of the closure element or past the free end of the closure element.
