Problems solved by technology

However, such pouch cells have the disadvantage that they have a relatively low inherent mechanical stability compared to battery cells configured prismatically or cylindrically, so that when connecting the pouch cells into Support structures are often required for battery modules

Abstract

The invention relates to a battery module sub-unit comprising a battery cell receptacle (2) which forms a receptacle space (3) for at least one battery cell (4), at least one battery cell (4) being received in the receptacle space (3) of the battery cell accommodation part (2), the battery cell accommodation part (2) forms a first connecting element (5), and the first connecting element is configured to be connected with another battery module sub-unit (1) in a shape locking manner. The battery cell receptacle (2) forms a second connecting element (6) on the side opposite the first connectingelement (5), which is designed to form a form-fitting connection to a further battery module sub-unit (1).

Description

technical field [0001] The invention relates to a battery module subunit of the type described in the independent claims. [0002] A battery module having a plurality of such battery module subunits is also the subject of the invention. Background technique [0003] It is known from the prior art that a battery module can consist of a plurality of individual battery cells which can be electrically conductively interconnected with one another in series and / or in parallel. [0004] Hybrid electric vehicles (HEV) and electric vehicles (EV) require high-energy and high-performance battery systems in order to be able to achieve the desired driving performance of their electric drives. [0005] In this case, high-energy and high-power lithium-ion or lithium-polymer cells are usually used as electrical energy stores, approximately 100 of which are connected to form a battery module. [0006] Such powerful battery cells each have a power of approximately 90 ampere hours (Ah). [...
