Example Embodiment

[0051] According to Figure 2~Figure 12 , A detailed description of the preferred embodiments of the present invention.

[0052] Such as Picture 11 As shown, the present invention provides a vehicle-use lithium-ion battery integrated module, including:

[0053] Several single battery modules, these single battery modules are arranged side by side, and are bonded with each other with structural glue to form an assembled plastic module;

[0054] The single battery module includes:

[0055] Thermally conductive frame 3 (made of thermally conductive plastic injection molding, base material is polyamide PA), such as image 3 with Figure 4 As shown, the thermally conductive frame 3 is a frame structure that can accommodate the single battery 1. The thermally conductive frame 3 has a hollow bottom plate 301 and a side plate 302 connected to the hollow bottom plate 301. The inner surface of the side plate 302 is in contact with the side surface of the single battery 1 Is coated with a laye...

Abstract

The invention discloses a vehicle lithium ion battery integration module and an integration method thereof. Single batteries are fixed to a heat conduction frame which has a heat conduction function through the structure glue adhering technology to form a single battery module, a plurality of single battery modules are fixed through the structure glue adhering technology, the module shaping technology and the bandage bundling technology, connection between aluminum strips and battery post terminals is carried out through the laser welding technology, and lastly the wiring harness terminal connecting and inserting technology and the upper cover fixing technology are carried out. According to the vehicle lithium ion battery integration module and the integration method thereof, battery unit splicing is adopted, the post terminals are connected through aluminum strip laser welding, reliability is greatly improved, and compared with the traditional nut locking technology, weight of the whole vehicle lithium ion battery integration module is reduced by about 10 percent to 40 percent.

Description

technical field [0001] The invention relates to the technical field of power battery module integration, in particular to a lithium-ion battery integrated module for vehicles and an integration method thereof. Background technique [0002] Such as figure 1 As shown, the outer frame design of the traditional battery module adopts the combination of the casing 1' and the upper cover 6', the single cells 2' are arranged side by side in the casing 1', and each single cell 2' has a battery upper cover 5' , The connection between the single cells 2' adopts the structure that the nut 3' locks the jumper 4'. Since the material of the positive pole of the single battery 2' is aluminum, it cannot withstand a large torque, and can only reach 1 / 10 of the locking torque of the steel stud 3', so the pole nut 3' is loose after being locked. potential risk, and a large number of nuts 3' also increases the weight of the entire module. Contents of the invention [0003] The invention pro...
