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

Abstract

The invention relates to a flexible package battery module, and belongs to the technical field of flexible package battery PACK. The flexible package battery module mainly solves the problem that an existing flexible package power battery pack is difficult to fix and realize series parallel connection. The flexible package battery module is characterized in that a plastic left fixed mount and a plastic right fixed mount are arranged on two sides of a flexible package battery cell respectively, and an aluminum sheet with two insulated surfaces is arranged on the outer side of the plastic right fixed mount; wiring channels are formed in two sides of the upper part of the plastic left fixed mount and two sides of the upper part of the plastic right fixed mount; the plastic left fixed mount, the flexible package battery cell, the plastic right fixed mount and the aluminum sheet are mutually engaged to form flexible package battery module units; the flexible package battery module units are overlapped to form an overlapping body, and the overlapping body is fixed to form a whole body through a plastic side plate I and a plastic side plate II on two sides; and a metal clamping seat and a head cover are arranged on each flexible package battery module unit. The flexible package battery module can guarantee the flexibility and vibration resistance of battery fastening, can also guarantee effective insulation between batteries; and the flexible package battery module has the advantages of small size, light weight, maintenance convenience and the like, and is mainly used for flexible package 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 ...
