Problems solved by technology

For each module, a fixed structure and connecting parts need to be added, which leads to an excessively large structural space of the battery module, thus occupying the internal space of the battery pack and causing a waste of space, thereby significantly reducing the energy density of the battery pack
In addition, conventional modules have multiple dependent parts, which also makes module assembly difficult and the overall weight of the battery pack is too large

Abstract

The invention relates to a soft package battery cell unit (10), and the soft package battery cell unit (10) at least comprises a housing (1) which comprises a carrier plate (2) and a frame (3); and a plurality of soft package battery cells (4) which are arranged inside the housing (1), are connected to each other by means of respective positive tabs (4.1) or negative tabs (4.2) and are surrounded by the frame (3), wherein the carrier plate (2) is rigidly designed and each soft package battery cell (4) is independently fastened to the carrier plate (2). The invention also relates to a corresponding manufacturing method and a corresponding battery pack. The structure of the flexibly packaged cell unit can be simplified, and the energy density of the flexibly packaged cell unit can be as high as possible.

Description

technical field [0001] The present invention relates to a pouch cell unit and a method for manufacturing such a pouch cell unit. Furthermore, the invention also relates to a corresponding battery pack. Background technique [0002] In recent years, with the development of new energy technology and the popularization of new energy vehicles, users have put forward increasing demands on battery energy density and cruising range. Advantages such as flexibility have received more and more attention. [0003] However, for assembly considerations, usually a plurality of pouch cells are arranged in a module, and then the module is arranged in a battery pack. For each module, a fixed structure and connecting parts need to be added, which leads to an excessively large structural space of the battery module, thereby occupying the internal space of the battery pack and causing waste of space, thereby significantly reducing the energy density of the battery pack. In addition, conventi...
