Embodiment Construction
[0061] It should be noted that, in the case of no conflict, the embodiments of the present invention and the features in the embodiments can be combined with each other.
[0062] The present invention will be described in detail below with reference to the accompanying drawings and examples.
[0063] Such as Figure 1-Figure 20 As shown, the battery module 20 of the battery pack according to the embodiment of the present invention includes: a multi-row cell assembly 201 , an intermediate connecting plate, an outer corner protector and an upper cover 204 . Multiple rows of cell assemblies 201 are arranged side by side, and the intermediate connecting plate is arranged between two adjacent rows of cell assemblies 201. The intermediate connecting plate is used to compress and space adjacent two rows of cell assemblies 201. It should be noted that, The intermediate connecting plate can be glued together with two adjacent rows of cell assemblies 201, so that two or more rows of ce...

The invention provides a battery module of a battery pack. The battery module of the battery pack comprises multiple lines of battery cell assemblies, an intermediate connection plate, an outer side protection corner and an upper cover, wherein the intermediate connection plate is arranged between two adjacent lines of battery cell assemblies, the outer side protection angle is arranged at an outer side of the battery cell assembly at the outermost side and is used for pressing the battery cell assembly at the outermost side, the outer side protection corner is connected with a lower shell ofthe battery pack, the upper cover is arranged at upper ends of multiple lines of battery cell assemblies and is connected at least one of the intermediate plate and the outer side protection corner. By matching of the multiple lines of battery cell assemblies, the intermediate connection plate, the outer side protection cover and the upper cover, the battery module has the advantages that an end plate and a side plate are not needed to be arranged compared with the battery module in the prior art, the internal space of the battery pack can be saved, so that the energy density of the battery pack can be improved, and the lightness of the battery pack also can be achieved; and moreover, the assembly efficiency of the battery module also can be improved, so that the production efficiency of the battery module can be improved.
Description
technical field [0001] The invention relates to the technical field of vehicles, in particular to a battery module of a battery pack. Background technique [0002] In the related art, the battery module in the existing battery pack is provided with an end plate and a side plate structure, the end plate and the side plate increase the weight of the battery module, and also occupy the space in the battery pack, which is not conducive to the light weight of the battery pack. Quantitative design and improvement of energy density. Moreover, during the assembly process of the upper cover of the battery module, the assembly steps are relatively complicated, resulting in a longer assembly time, and the assembly reliability of the upper cover is not good, and it is easy to loosen. Contents of the invention [0003] In view of this, the present invention aims to provide a battery module of a battery pack to solve the problems of heavy weight and low energy density of the battery pa...
