NOVELTY - The mounting device (3) for a battery module for an electric vehicle, comprises a support structure (2) comprising supporting parts (4, 5) engaging below the battery module, which is rigidly connected to the support structure. The support structure comprises a first supporting part and a second supporting part, where the supporting parts are connected to each other on different sides of the battery module by tie rods (8). The tie rods are arranged normal to the stacking direction of the battery cells. Each of the tie rods has a fastening screw.    USE - The mounting device is useful for a battery module for an electric vehicle.    ADVANTAGE - The light-weight mounting device ensures economical and reliable mounting of the battery in the vehicle.    DETAILED DESCRIPTION - The mounting device (3) for a battery module for an electric vehicle, comprises a support structure (2) comprising supporting parts (4, 5) engaging below the battery module, which is rigidly connected to the support structure. The support structure comprises a first supporting part and a second supporting part, where the supporting parts are connected to each other on different sides of the battery module by tie rods (8). The tie rods are arranged normal to the stacking direction of the battery cells. Each of the tie rods has a fastening screw that is positively and/or frictionally screwed with the first and second supporting parts. The tie rod is arranged within the battery module. The battery module is arranged in a battery housing (1), where the supporting parts are fixedly connected with a battery module surrounding the battery housing. The supporting part is arranged between the battery module and the battery housing. The first supporting part is arranged in a bottom area of the battery housing, and the second supporting part is arranged in a ceiling area of the battery housing and/or the battery module. One of the tie rods penetrates the battery housing, which is fixedly connected with the supporting part via a nut and/or a screw head of the tie rod. The supporting part is formed by an extruded profile, has a trapezoidal cross-section, and is made of polyamide. A sealing unit is arranged between the supporting part and the housing and/or between the supporting part and the battery module. The battery housing comprises a stiffening rib that is parallely extending in an area of the supporting part. The battery module is thermally decoupled from the support structure, where a heat insulating part is arranged between the battery module and the battery housing. The battery housing consists of two housing parts, which are fixedly glued together at overlapping surfaces of a flange. An INDEPENDENT CLAIM is included for a battery unit with a battery module for an electric vehicle.    DESCRIPTION OF DRAWING(S) - The figure shows a battery unit with a mounting device.
