NOVELTY - The carrier (11) has a base including a support surface for a vehicle battery (100) and projections (14, 15) i.e. domes, protruding from the base in which the vehicle battery is placed. A holder (51) is attached to the projections, which secure the vehicle battery in position along direction of a spatial axis (z), where the projections are formed on the carrier. The projections are formed on the base and on a side wall of the carrier and placed at distance from an adjacent side of the carrier, and extend into an area of an upper side (110) of the vehicle battery.    USE - Trough shape carrier for use with a clip shape holder i.e. injection molded part, in a preassembled unit (all claimed) i.e. fastening device, for fixing a battery i.e. starter battery, in an electric-motor driven vehicle. Can also be used for a traction battery.    ADVANTAGE - The vehicle battery is located in a recess of the vehicle body and adequately fixed, so that installation and disassembly of the vehicle battery can be carried out in a simple manner. The carrier adequately fixes the vehicle battery in a recess or depression of the motor vehicle in a simple manner. The vehicle battery has ergonomically favorable reachability of the components for fixing the vehicle battery, so that individual components of the fastening concept are pre-positioned for the vehicle battery, thus reducing assembly effort overall and assembly time for the vehicle battery, and hence avoiding transport of parts and achieving cost savings in an efficient manner. The carrier reduces dimensions of the vehicles and overall weight to meet legal requirements for the reduction of carbon-di-oxide emission. The carrier allows a reinforcing element to prevent release of the connection during settling effects of plastic material. The projections are placed at distance from an adjacent side wall of the carrier, so that free installation space can be achieved between one of the projections and neighboring side wall, which can be used for receiving components of the vehicle or supplementary components such as fuse box or cable. The carrier protects environment around the carrier from escaping battery fluid, which remains inside the carrier as a result of the trough shape.    DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for a preassembled unit for fixing a vehicle battery in a motor vehicle, comprising a holder.    DESCRIPTION OF DRAWING(S) - The drawing shows a perspective view of a fastening device for a vehicle battery integrated in a motor vehicle.
