The invention discloses a novel square
lithium battery standardized module encapsulation case and a PACK method. The novel square
lithium battery standardized module encapsulation case comprises an upper box, a lower box, a box cover and an
electrode substrate, wherein the centers of the front end and the rear end of the outer side of the box cover are inward punched to form a mounting groove, a mounting boss is formed on the front end and the rear end of the inner side of the box cover, a strip-shaped clamp slot is formed in the outer side end of the mounting groove, the
electrode substrate is fixedly connected with the mounting boss, a first card is arranged at the center of one side of the
electrode substrate, and is vertically folded to form a second card, and the second card is foldedto form a third card; the electrode substrate is arranged inside the box cover; the upper box and the lower box are mutually clamped to form a standardized
battery pack unit; and a plurality of standardized
battery pack units are sequentially spiced. Through the mutually embedded structure design and automatic mutual embedded limitation, a large
battery pack is facilitated to be efficiently and rapidly assembled, all
welding technologies can be avoided, the battery packing cost can be effectively lowered, and the disassembling and maintenance are also convenient; the heat dissipation effect is obvious, meanwhile the weight is lightened, and the weight
energy density of the battery module is beneficially improved.
