Abstract

The invention discloses a lightweight battery module. The lightweight battery module comprises a battery module main body, the left side and the right side of the battery module main body are respectively provided with an end plate. An end plate insulating sheet is arranged between the battery module main body and each end plate. The battery module main body comprises a plurality of battery cells.An annular inter-cell buffer pad is arranged between any two adjacent cells. The front ends and the rear ends of the two end plates are each fixedly connected with a side plate. The FPC output end connector bracket is mounted at the upper part of one end plate in an inserting manner. The FPC output end connector is inserted into the FPC output end connector bracket. The FPC is bonded with the topof the battery cell, and a plurality of busbars are respectively arranged on the front side and the rear side of the top of the battery module main body. According to the lightweight battery module disclosed by the invention, by optimizing the structure, a plastic frame bracket between the battery cell and the busbar is omitted, the reliability of the whole structure is good, and a positive effect is achieved on the improvement of the energy density and the reduction of the cost.

Description

technical field [0001] The invention relates to the technical field of batteries, in particular to a lightweight battery module. Background technique [0002] At present, with the requirements of battery life and price for electric vehicles, the low cost and light weight of the battery system are becoming more and more important. Among them, the light weight and low cost of the battery module are particularly important. [0003] However, most of the current solutions are to make the module bigger and reduce the weight shared by each component, while the simplification of the module structure is often ignored; among them, the plastic isolation bracket as an important structural part of the module, its cost It accounts for 5% to 10% of the cost of the module structural parts, and in order to avoid the explosion-proof valve of the battery cell and fix the aluminum row, the upper cover, etc., the design structure of the plastic isolation bracket is complicated, and the mold cost...
