Abstract

The invention provides a battery pack structure and an electric vehicle, and relates to the technical field of a battery structure of the electric vehicle. The battery pack structure comprises a negative electrode aluminum row, a lower supporting frame, a cell, an upper supporting frame and a positive electrode aluminum row, wherein the negative electrode aluminum row is fixedly connected with the lower supporting frame; the lower supporting frame is fixedly connected with the upper supporting frame; the upper supporting frame is fixedly connected with the positive electrode aluminum row; and the cell is fixedly mounted between the lower supporting frame and the upper supporting frame. According to the scheme, the cell and the positive electrode aluminum row and the negative electrode aluminum row are in tight contact, so that small deformation and low cost are realized; and meanwhile, the assembling difficulty and detaching difficulty of the battery pack are lowered, and relatively low vibration resistance and relatively low contact resistance are realized.

Description

technical field [0001] The invention belongs to the technical field of battery structures of electric vehicles, and in particular relates to a battery pack structure and an electric vehicle. Background technique [0002] In the prior art, the cells of the battery pack and the aluminum row are fixedly connected by welding, but the welding process is complicated, which makes the assembly efficiency of the battery pack low, resulting in an increase in production cost; and in the above When the battery pack is recycled and reused, there is a problem that it is difficult to disassemble the battery cell and the aluminum row, which will cause damage to the battery cell and the aluminum row during the disassembly process. Contents of the invention [0003] The purpose of the present invention is to provide a battery pack structure and an electric vehicle, so as to solve the problems in the prior art that the welding process of the battery cell and the aluminum row is complicated a...
