Abstract

The invention discloses a battery module, an automobile using the battery module, and an assembly method of the battery module. According to the present invention, the tabs of the unit cells in the battery module can be subjected to welding pre-pressure during the assembly process, and can be welded under the action of the welding pre-pressure, thus making the welding process for realizing the connection of the tabs easy to control , so that the connection reliability of the tab can be improved.

Description

technical field [0001] The invention relates to battery assembly technology, in particular to battery modules, automobiles, and battery module assembly methods. Background technique [0002] New energy vehicles usually require the use of batteries, such as lithium-ion batteries. Moreover, batteries are usually used in new energy vehicles in the form of battery modules. However, the connection reliability of the tabs of the battery in the battery module needs to be high, mainly because the connection process of the tabs is not easy to control. Contents of the invention [0003] One embodiment of the present invention provides a battery module in which connection reliability of tabs of batteries can be improved. And, the battery module includes: [0004] A unit battery, the unit battery includes a battery body and tabs protruding from the battery body; [0005] A battery frame, the battery frame is installed on the outer periphery of the battery body, and the outer side ...
