A battery module () for the purely electric driving of a motor vehicle has a trough-shaped battery box () that runs around a circumferential direction, an inlet for feeding a coolant into a cooling space () partially bounded by the battery box (), an outlet for conducting the coolant away from the cooling space (), battery cells () in the battery box () and arranged in the cooling space (), and an insulating layer () for fluid-tight sealing of the cooling space (). At least one electrical pole () of the battery cell () projects out of the cooling space () through the insulating layer (). The insulating layer () is formed from a previously liquid cured sealing compound. The insulating layer () can simultaneously make available a high sealing effect and a statically stabilizing effect for the battery box () together with a low intrinsic weight.

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.

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.
