  "description_excerpt": "The present invention relates to an arrangement for fastening an energy storage module on a module carrier, particularly a vehicle body.\n\nIn a device, usually called a battery, for supplying power to a motor vehicle, a plurality of energy storage modules are normally used for driving the vehicle, for example, electric vehicles or hybrid vehicles. A respective energy storage module typically consists of several stacked prismatic storage cells. The individual storage cells contain electrochemical cells of the battery. The stack on the individual storage cells is usually braced by means of a mechanical end plate (also called “pressure plate”) and a tension member for forming the energy storage module. Additionally to mechanically fixing the modules with respect to one another, the end plates and tension members are particularly used for counteracting a deformation as a result of gas pressure changes, which occur during the operation in the electrochemical cells arranged in the interior of the modules.\n\nThe energy storage modules are mounted in devices for the power supply, particularly in motor vehicles. This usually takes place by means of a fastening device, for example, a bolt or a screw. For the connection between the bolt and the energy storage module, projections had previously been provided at the energy storage module. The fastening device is fitted through these projections and can thereby be connected by screwing, for example, in the motor vehicle. These projections protrude beyond the energy storage module and thereby unfavorably increase the installation space for the energy storage module.",
