Embodiment Construction

[0069] figure 1 The structure of the battery module 1 according to the invention is shown schematically in an exploded view.

[0070] In this case, the battery module 1 has a plurality of battery cells 2 .

[0071] according to figure 1 , the battery cells 2 are each configured here as circular cells 20 .

[0072] In this case, the battery cell 2 , 20 forms a first voltage tap 31 on the first side 21 .

[0073] In this case, the battery cell 2 , 20 forms a second voltage tap 32 on the second side 22 .

[0074] In this case, the first side 21 is configured differently from the second side 22 and is arranged opposite the second side 22 .

[0075] Here, the first side surface 21 may be a first end surface, and the second side surface 22 may be a second end surface.

[0076] For example, the first voltage tap 31 may be a positive voltage tap and the second voltage tap 32 may be a negative voltage tap.

[0077] Here, the battery cells 2 , 20 are also arranged in the branch pa...

Abstract

The invention relates to a battery module. The battery is provided with a plurality of battery cells (2), the battery cells are respectively provided with a first voltage tap (31) on a first side surface (21) and a second voltage tap (32) on a second side surface (22) opposite to the first side surface (21). Wherein the battery cells (2) are arranged in a plurality of branch lines (4) of the battery module (1), and the battery cells (2) of the branch lines (4) are arranged alternately in the longitudinal direction (7) of the respective branch line (4).

Description

technical field [0001] The invention relates to a battery module of the type according to the independent claim. Background technique [0002] Battery-operated motor vehicles (electric vehicles) usually have a battery consisting of a plurality of battery modules which are connected to one another in an electrically conductive manner. [0003] In this case, the battery modules can be electrically connected to each other in series and / or in parallel, in order to meet the respective requirements placed on the battery modules. [0004] In this case, such a battery module also consists of individual battery cells electrically connected to one another in series and / or in parallel. [0005] The requirements placed on such a battery of an electric vehicle may be, for example, the available installation space in such a vehicle and the required power or required form of energy. [0006] Batteries of battery-operated motor vehicles can generally have an operating voltage in the high-...
