Problems solved by technology

This connection method is very convenient for thicker blade batteries, but it is not conducive to the multi-parallel connection of thinner blade batteries.
For thinner blade batteries, or two or more battery modules, this structure is difficult to assemble

Embodiment Construction

[0030] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.

[0031] It should be noted that all directional indications (such as up, down, left, right, front, back...) in the embodiments of the present invention are only used to explain the relationship between the components in a certain posture (as shown in the accompanying drawings). Relative positional relationship, movement conditions, etc., if the specific posture changes, the directional indication will also change accordingly.

Abstract

According to the blade battery pack structure, a blade battery pack is an electric pile formed by stacking a plurality of battery cell monomer groups, and each battery cell monomer group is formed by stacking a plurality of blade battery cell monomers; a tab is arranged on each blade battery cell monomer; tabs of the blade battery cell monomers in each battery cell monomer group are pressed on the same PCB fixing plate through pressing strips; the pressing strip and the PCB fixing plate are locked through a screw joint assembly. And the PCB fixing plates between the adjacent battery cell monomer groups are connected through isolation columns. According to the invention, tabs of the blade battery cell monomers are fixed by adopting the screw joint assemblies along the thickness direction of the battery cell, the plurality of blade battery cell monomers are stacked to form the battery cell monomer group, and then a stack structure formed by stacking the plurality of battery cell monomer groups is adopted; and the convenient assembly requirement of thin battery cells or multi-layer tabs (more than two layers), which cannot be met by a screw joint locking mode along the extending direction of the tabs on the blade battery cell monomers in a traditional connection mode, is effectively solved.

Description

technical field [0001] The invention relates to the technical field of power batteries, in particular to a blade battery pack structure. Background technique [0002] Among the existing power batteries, there are generally three types of soft pack batteries, prismatic batteries and cylindrical batteries. Among them, the pouch battery is called a blade battery because of its thinner thickness and the shape of a blade. Due to the high specific energy of blade batteries, good heat dissipation effect and high space utilization rate, blade batteries are more and more popular in the high specific energy and high rate discharge mode. In order to apply blade batteries to products, the modular design of blade batteries is essential. [0003] The core of the modular blade battery is the series-parallel connection of the tabs between the blade batteries. The existing connection methods include laser welding, ultrasonic welding, screw connection, riveting and so on. Among them, weld...
