Problems solved by technology

[0010] On the other hand, the following technical disadvantage has to be faced: the mountability of such flexible batteries in the module housing or system housing is complicated
The main disadvantage of the fixation solutions so far is that the battery is embedded in a somewhat complex frame
This often leads to high investments in the case of plastic or polymer frames, e.g. for new tools
Therefore, the advantages of rapid and economical scalability of battery size cannot be effectively used
[0015] In addition, the manufacturing process of the frame is slow compared to the manufacturing process of the battery
Therefore, the frame production process is the bottleneck of battery system production
or the frame must be manufactured with multiple parallel devices or tools
This requires high investment

Embodiment Construction

[0067] figure 1 A schematic diagram shows a soft-pack battery, that is, a galvanic battery with a flexible casing. The soft-pack battery includes an actual battery body 1 and a surrounding sealing seam 2. An electrode-separator layer structure is provided on the body of the battery. The upper and lower decorative films in the area of ​​the sealing seam are welded to each other, and include a discharge terminal 3 extending from the battery between the cover films and additionally sealed with a film. Here, the discharge terminals 3 may protrude from the housing on the same side surface, or may also be located on different sides.

[0068] During the operation of the battery, that is, during charging and / or discharging, the thickness of the battery body 1 usually varies between the charged and discharged states by 5% to 10%. In addition, aging batteries are about 5% thicker than new batteries. Therefore, an aged and charged battery is about 10% to 15% thicker than a new and uncharge...

Abstract

The invention relates to a receiving element (4) for mounting pouch cells, has a base body. The receiving element comprises a base body (5). With respect to an object of receiving the pouch cells securely and cost-effectively in a frame or housing, the receiving element is characterized in that the base body (5) is formed as a profile having a contact surface (5a) for contact against a sealing seam (2) of a pouch cell.

Description

Technical field [0001] The invention relates to a receiving element for a pouch battery according to the preamble of claim 1. Background technique [0002] For example, large-format battery systems based on lithium technology, such as lithium ion, lithium polymer, and lithium sulfur, can be used in a variety of applications. Usually a battery system includes 50 to 200 batteries. Thousands of batteries are also common in large-sized accumulators. [0003] Usually 6 to 12 batteries are used for each module, and the number of batteries is mostly limited by the module voltage of 50V. Above 50V, the module is regarded as a high-voltage component. [0004] The battery can exist in different implementation forms, namely, as a circular battery with a fixed metal casing, as a prismatic battery with a fixed metal casing, or as a soft pack battery with a flexible film casing. The soft pack battery has obvious advantages over the battery structure with a fixed metal casing. [0005] Because t...
