Problems solved by technology

[0005] Therefore, a large number of cables of different lengths are required to produce a corresponding electrical energy store, the correct provision of which is complex and possibly faulty.
Furthermore, such a set of connecting cables with a predetermined length limits the positioning possibilities of the controller and the battery modules inside the electrical energy store

Embodiment Construction

[0035] exist figure 1 A battery module 10 according to a first embodiment of the present invention is shown in . The battery module 10 is included in the figure 1 The battery cells, not shown, are electrically connected to one another in series or in parallel, for example. The battery module 10 includes a battery module housing with side walls 12 and a housing cover 14 . The housing cover 14 has, for example, a first connection point 16 , which is used, for example, for electrical contacting of the battery module 10 or for data-technical contacting of the battery module 10 . For example, if the measurement signal can be transmitted via the connection point 16, for example from a sensor installed in the battery module, or if the connection point 16 is in electrical contact with the measurement leads which are themselves connected to the individual battery cells of the battery module 10, there is a data technology contact on. The first connection point 16 is here preferably ...

Abstract

Described is a battery module comprising a plurality of battery cells which are electrically interconnected in parallel or in series, and comprising a battery module housing which is provided with atleast two connection points for a data-carrying or current-conducting cable and with at least four cable guides for guiding a data-carrying or current-conducting cable connected to the connection points to another battery module or data receiver, wherein the cable guides (20a-20f) end at different outer edges of the battery module housing, and wherein the sum of a cable-guide length of a first cable guide (20a-20c) and the cable-guide length of a second cable guide (20d-20f) is equal to the sum of a cable-guide length of a third cable guide and a cable-guide length of a fourth cable guide.

Description

technical field [0001] The invention relates to a battery module according to the preambles of the independent claims, to a battery pack comprising the battery module, and to the use thereof. Background technique [0002] Electric energy stores are used in hybrid, plug-in hybrid and electric vehicles in order to store the necessary energy for the electric motor which supports the drive or itself serves as the drive. Such an electrical energy store is realized, for example, in the form of a lithium-ion battery, which contains a plurality of individual battery cells, which are themselves electrically connected to one another in series or in parallel in a plurality of battery modules. Here, there is a need to electrically connect the different battery modules of the battery to one another, which can also be achieved in certain cases by means of cable-connected solutions. [0003] Furthermore, such electrical energy stores require complex systems for monitoring the battery modu...
