Problems solved by technology

[0004] Cylindrical cell modules come in all shapes and sizes, which makes it more difficult for designers to design modules. Up to now, there is no plan to use cylindrical cell modules to replace square cell VDA modules; it is also inconvenient to standardize the design of cylindrical cells, resulting in battery packs Reduce cost and increase difficulty

Embodiment Construction

[0044] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0045] Such as Figure 1-8A plurality of cylindrical batteries (3) are arranged between the upper support (8) and the lower support (2) as shown, and the three are passed through the side walls of the round holes in the upper support (8) and the lower support (2) or The VU glue pre-coated on the bottom is cured and fixed, so that the cylindrical cell (3) is integrated with the upper bracket (8) and the lower bracket (2);

[0046] The support plate 1 (1) and t...

Abstract

The invention provides an electric vehicle battery module and a busbar for the battery module, and relates to the electric vehicle battery technology field. According to a technical scheme, a batteryframe body, a battery cell, a partition plate and an upper cover are included; the battery cell is placed in the battery frame body; a busbar is arranged above a positive electrode of the battery cell; the battery frame body comprises an upper support and a lower support; a plurality of battery cells are arranged between the upper support and the lower support; supporting plates are arranged at four corners of the upper support and the lower support, fixing holes penetrating up and down are arranged in the supporting plates, the whole battery module is fixed on a battery pack shell through fasteners in the fixing holes, two side edges of each supporting plate extend outwards, and reinforcing ribs are arranged at extending parts. By using the electric vehicle battery module and the busbar for the battery module, the battery module is compact in structure through reasonable cooperation of the upper support, the lower support and all structural components, a requirement for electrical safety is satisfied, usage is convenient, and meanwhile, under a same boundary dimension of the battery module, the number of battery cells is maximum, and the requirement of a high electric quantity issatisfied.

Description

technical field [0001] The invention relates to the technical field of batteries of electric vehicles, in particular to an electric vehicle battery module and a bus bar for the battery module. Background technique [0002] With the enhancement of global environmental protection awareness, in response to the environmental protection policy of energy saving and carbon reduction, electric vehicles are gradually favored by everyone. They are non-polluting, meet environmental protection requirements, are safe and fast, and make electric vehicles more and more widely used. [0003] Electric vehicle batteries are the main source of power for electric vehicles, and the quality of electric vehicle batteries directly affects the performance of electric vehicles. Among them, the strength and fixation of the module, the energy density of the module, thermal management, and busbar confluence treatment are related to the performance of the entire battery pack; [0004] Cylindrical cell m...
