A soft pack battery module

Abstract

The name of the present invention is a soft pack battery module. It belongs to the technical field of soft pack battery PACK. It mainly solves the problems that the existing soft-pack power battery packs are difficult to fix and realize series-parallel connection. Its main features are: there are plastic left and right plastic fixing frames on both sides of the soft-packed battery, and two insulated aluminum sheets are arranged on the outside of the plastic right fixing frame; the plastic left fixing frame and the plastic right fixing There are wiring grooves on both sides of the upper frame; the plastic left fixing frame, the soft-packed battery cell, the plastic right fixing frame and the aluminum sheet are interlocked to form a soft-packed battery module unit; the soft-packed battery module unit is stacked into a laminated body , the composite body is fixed into a whole by the plastic side plate 1 and the plastic side plate 2 on both sides; a metal holder and a top cover are arranged on the pouch battery module unit. The invention can not only ensure the reliability and vibration resistance of the battery fastening, but also ensure the effective insulation between the batteries, has the advantages of small size, light weight and convenient maintenance, and is mainly used for soft pack power battery packs.

Description

technical field [0001] The invention belongs to the technical field of soft pack battery PACK, and in particular relates to a novel soft pack battery module. Background technique [0002] Soft-pack batteries refer to lithium batteries whose shells are made of soft packaging materials (usually aluminum-plastic composite films), which have many advantages such as small size, light weight, high specific energy, high safety, and flexible design. The structure of the soft-pack power battery (or soft-pack battery) is packaged with aluminum-plastic film, and the positive and negative electrodes of the battery also use the battery tab structure, which is different from the usual plastic case and metal case batteries. Due to the soft shape of the soft-pack power battery, it is not easy to fix, and it is prone to scratches, pits, creases, etc., so the fastening and series-parallel connection of the soft-pack power battery are two major difficulties in the integration of the soft-pack ...

AI Technical Summary

Problems solved by technology

Due to the soft shape of the soft-pack power battery, it is not easy to fix, and it is very prone to scratches, pits, creases, etc., so the fastening of the soft-pack power battery and the series-parallel connection are two major difficulties in the integration of the soft-pack power battery pack.

At present, there are few researches on the integration technology of soft-pack power battery packs. Some enterprises or research laboratories of universities use soft-pack power batteries to be installed in PVC plastic shells made by mold opening, but the volume and weight are relatively large, which greatly reduces the The energy density of the soft pack power battery pack cannot reflect its superiority
