Embodiment 1

[0022] Embodiment 1: a battery module, such as figure 1 and figure 2 As shown, it includes battery pack, two end insulating sheets 2, two fixed end plates 1, cover plate 6, plastic bracket 1312, output pole 3, FPC4, bus aluminum sheet 5, plastic strap 9, metal strap 10 and the reinforcing plate 8, the battery pack includes 4 cell packs 7, each cell pack 7 includes several single cell cells, and the single cell cells are bonded by glue to form a cell pack 7, 4 cell packs 7 is a double-row distribution arrangement, the intermediate insulating sheet 11 is arranged between the two rows of battery packs 7, the reinforcing plate 8 is arranged between the two rows of battery packs 7, and the two fixed end plates 1 clamp and fix the battery packs, The end insulating sheet 2 is installed between the fixed end plate 1 and the battery pack. The four cell packs 7 are bound by metal straps 10 and plastic straps 9 to form a battery pack as a whole. The plastic bracket 1312 is installed on...

Embodiment 2

[0023] Embodiment 2, a battery module, such as image 3 As shown, the difference between this embodiment and the first embodiment is that the reinforcing plate 8 of this embodiment includes a base, a fixed rod 14, a torsion spring 15 and a movable plate 16, the base is installed between the battery packs 7, and the fixed rod 14 is fixedly installed on the base, the torsion spring 15 is installed on the fixed rod 14, the movable plate 16 is provided with an installation groove matching the torsion spring 15, and the movable plate 16 is movably installed on the fixed rod 14 through the matching connection between the installation groove and the torsion spring 15. On the top, the cover plate 6 is also provided with a limit hole matching the cover plate 6 , and the elastic potential energy of the torsion spring 15 is smaller than that of the plastic strap 9 . The rest of the structure is the same as that of the first embodiment.

Abstract

The invention discloses a battery module group, which includes several cell groups, and each cell group includes several single cells for providing electric energy; a bus aluminum sheet is used for connecting several single cells Conduction, connected to the battery pack; output pole, used to output the electric energy stored in the battery pack, connected to the bus aluminum sheet; fixing device, used to fix several battery packs to form a battery module; the invention cancels The aluminum side plate of the module uses metal straps and plastic straps to fix and constrain the module. It can be assembled directly without welding, which simplifies the assembly process of the module and reduces the manufacturing cost; Large module size reduces the structural parts of the module and reduces the cost of the structural parts of the module; a battery pack can contain more single cells, the number of modules is greatly reduced, and the number of connecting copper bars between modules is reduced, reducing the cost of the entire battery. The cost of the package system.

Description

technical field [0001] The present invention relates to the technical field of batteries, in particular to a battery module. Background technique [0002] In order for new energy vehicles to be accepted by the public, it is necessary to solve the concerns of consumers, one is battery life, the other is charging convenience, and of course cost performance. At present, the main concern of everyone is the battery life of new energy vehicles, whether it can be like a traditional gasoline vehicle without worrying about its mileage. [0003] As we all know, a battery pack system is roughly composed of battery modules, battery boxes, thermal management systems, battery control systems (BMS) and other components. The battery module is mainly composed of battery cells and structural parts. The number of cells in a battery pack system determines how much power it can store, corresponding to how much battery life the car can have. [0004] In the traditional battery pack system, gen...
