• a connecting sleeve 8 can now be introduced into the bores 15 through the grooves 14 of the battery modules. As a result, even a mounting of the connecting sleeve is possible if both battery modules 1, 1 'and the respective terminals 5, 5' are already in contact with each other.
• the battery module 1 has a chamfer 16, which is arranged in the boundary region between the two outer surfaces 3i, 3 3 , as can be seen in particular from Figure 8 b. This chamfer provides improved access to the terminals, for example by an external tool.
• FIG. 10 shows the outer surface S 1 of a battery module 1 in an advantageous embodiment.
• the outer surface 3i has a plurality of projections 17 projecting outwardly from the outer surface S 1 .
• the projections 17 serve as spacers to a further battery module to be arranged adjacently. The thus generated distance between two battery modules allows for improved heat dissipation and feed.
• the projections themselves can be used as cooling ribs. serve pen.

• the battery modules according to the invention can be used for battery arrangements of various configurations.
• the battery modules can be mounted in a wide variety of geometric arrangements.
• the usual bulky block form of conventional battery units is dissolved and replaced by a flexible modular system, which allows utilization of small winding installation spaces in the vehicle, as shown in FIG 11 is shown.
• FIG. 11 schematically shows a detail of an engine compartment 19 from a motor vehicle.
• the components 18 may be any of a number of types of components disposed in an engine compartment, such as those shown in FIGS. Units, body parts, hose connections or cables.
• the continuing development of automobiles means that new components are always introduced into the engine compartment or that the existing components sometimes require an increased amount of space.
• This development is in tense relationship with the fact that the exterior dimensions of the vehicle must not exceed a certain maximum and the passenger compartment should be designed as large as possible. Among other things, this means that the space required in the engine compartment of a vehicle is tight.
• a plurality of battery modules 1 can now be seen, which are lined up in a seemingly arbitrary manner.
• the available space between the components 18 is optimally utilized with the battery modules 1.
• the battery assembly which is formed from the plurality of battery modules 1, only be assembled during the final assembly of the vehicle from the individual battery modules 1.
• the individual components 18 are mounted in the engine compartment 19.
• the battery modules 1 are arranged around the components 18 around and joined together.
• at least a first battery module 1 is fixedly mounted in the engine compartment 19, wherein it is attached to a structural unit of the vehicle or to a component, which is preferably already firmly connected to the vehicle.
• further battery modules 1 are mounted and at least indirectly connected to the first battery module.
