Problems solved by technology

A disadvantage of the hitherto known battery packs is that the connection of the individual battery cells is generally technically complex
In addition, mechanical forces that typically occur when or after connecting the battery cells may negatively affect the electrical connection between the battery cells

Embodiment Construction

[0033] figure 1 A cross-sectional view of a first embodiment of a battery pack 5 according to the invention is shown. figure 2 show from figure 1 Side view of the battery pack 5. image 3 show from figure 1 or figure 2 A perspective view of the battery cells 10, 60 of the battery pack 5. Figure 4 show from image 3 Detail view of area IV of battery cell 10, 60 of FIG. Figure 5 show from image 3 Another perspective view of the battery cells 10, 60 of FIG.

[0034] The battery pack 5 comprises a plurality of battery cells 10 , 60 which are connected one behind the other in series. The battery pack 5 can in particular be a lithium-ion battery pack, which comprises a plurality of lithium-ion cells.

[0035] The battery or battery cells 10 , 60 (in particular the first battery cell 10 and the second battery cell 60 of the battery pack 5 ) are in the first direction 7 (the first direction is in figure 1 Stretching from bottom to top) Arranged up and down. The battery...

Abstract

The invention relates to a battery pack, which includes at least one first battery and at least one second battery; in a first direction, the first battery and the second battery are arranged vertically; the first battery is provided with a plurality of projections that electrically connect the first battery with the second battery; the projections leave from the first surface of the first batteryand basically extends to the first direction; the second battery has a plurality of gaps, each of which is used for accommodating every projection. The projections on the first battery are arranged inside the gaps in the second battery so that a plurality of contact surfaces are formed between the projections and the gaps in order to electrically connect the first battery and the second battery.The contact surfaces are extended in the direction basically in parallel to the first direction.

Description

technical field [0001] The invention relates to a battery comprising a first battery cell and a second battery cell and a method for electrically contacting the first battery cell and the second battery cell for assembling the battery. Background technique [0002] A large number of different batteries are known, each comprising a plurality of battery cells. A disadvantage of the hitherto known batteries is that the connection of the individual battery cells is often technically complex. Furthermore, in particular when high-current connections between the battery cells are to be produced, additional connecting elements are often required for connecting the battery cells to one another. Furthermore, mechanical forces that typically occur when connecting the battery cells or after connecting the battery cells may negatively affect the electrical connection between the battery cells.
