Abstract: A battery module has at least four battery cells that are cooled via a cooling plate arranged between them. Fins project on the cooling plate and at the same time serve as stops for individual battery cells. As a result, a powerful and very rigid battery module is provided that is of structurally simple construction.

Abstract: A battery device has at least two interconnected battery modules and at least one cooling plate arranged between two battery modules for cooling the battery modules. A housing encases the battery device and is provided with a frame structure. The at least one cooling plate is traversed by a flow of fluid and is formed from two metal layers that are connected to one another. Additionally, the at least one cooling plate is connected fixedly at least by its ends to the frame structure and stiffens the frame structure. Thus, the battery device exhibits high power and is robust.

Abstract: A variable aerodynamic device for a vehicle, comprising: a wing element (1) having a front and a rear; a frame or body (2) for mounting to a vehicle; a linear actuator (4, 5) mounted between the body (2) and a first mounting point or first location (8) on the wing element for moving the rear of the wing element between a raised position and a lowered position relative to the body; and a guide strut or linkage (9) mounted between the body and the wing element, the linkage being pivotally coupled to the wing element at a second mounting point or second location (10) forwards of the first location (8); the linkage being configured such that when the rear of the wing element is moved by the linear actuator between the raised position and the lowered position, the second location moves rearwardly relative to the body.
