Abstract

The invention discloses a welding-free square lithium battery module, which comprises structures such as a square lithium battery, a cold plate, an insulating plate, an electrode contact piece, a fixing frame, and a pressing plate. The inside of the square lithium battery module does not need to be welded. The connection between the liquid inlet and outlet on the cold plate and the sealing joint can be used to quickly connect the cells in series and parallel, and the modules can be freely combined. The welding-free square lithium battery module of the present invention reduces the damage caused by battery welding, enhances the heat dissipation (heating) capacity of the battery, improves the utilization efficiency of the battery, and enhances the free combination ability of the square lithium battery with lower cost and means. And heat dissipation (heating) capacity, reduce the temperature of the prismatic lithium battery, balance the temperature difference between the battery and the module, increase the reliability of the prismatic battery module, and prolong the service life of the equipment used by the prismatic lithium battery module.

Description

technical field

[0001] The invention relates to the technical field of square lithium batteries, in particular to a square lithium battery module that is mechanically connected, has an independent heat dissipation (heating) structure, and is free of welding. Background technique

[0002] Lithium batteries are widely used because of their high energy density, long service life, no memory effect, and no toxic and harmful substances such as lead. In order to meet the capacity and voltage requirements, lithium batteries usually need to be combined into battery packs for use. The grouping method of traditional lithium battery packs is to fix the conductive parts with screws, which easily leads to the risk of single point failure; the conductive parts are grouped and fixed by welding, the conductive contact area is small, and it is difficult to achieve single-section replacement and maintenance, especially not conducive to cascade reuse , there is an urgent need to develop a mech...
