Problems solved by technology

[0004] The invention provides a low-cost battery for electric vehicles and its assembly process, which is used to solve the problem that the inside of the existing battery consists of a sealing body and a bare cell from top to bottom, and the sealing body is squeezed upward through the bare cell, and the sealing body Squeeze the inner wall of the mouth of the battery case upward to realize the sealing of the battery. When the axial length of the bare cell is insufficient, the sealing body will not be able to fit tightly with the inner wall of the mouth of the battery case, thus affecting the technical problem of the sealing effect of the battery.

Abstract

The invention provides a low-cost battery for an electric automobile and an assembly process thereof, the battery comprises an aluminum shell and a naked battery cell, the naked battery cell is arranged in the aluminum shell, a sealing body is arranged at an opening of the aluminum shell, the sealing body is provided with a concave arc-shaped curved surface groove, the aluminum shell is columnar, the aluminum shell is provided with an aluminum shell flanging part, and the aluminum shell flanging part is provided with a concave arc-shaped curved surface groove. The flanging of the aluminum shell is provided with an inward-concave arc-shaped curved surface body in the circumferential direction of the aluminum shell, and the inward-concave arc-shaped curved surface body is used for being matched with the inward-concave arc-shaped curved surface groove in shape. The battery can solve the problems that the sealing body and the naked battery core are sequentially arranged in the existing battery from top to bottom, the naked battery core upwards extrudes the sealing body, the sealing body upwards extrudes the inner wall of the opening part of the battery shell to realize sealing of the battery, and when the axial length of the naked battery core is insufficient, the sealing body cannot be tightly attached to the inner wall of the opening part of the battery shell; therefore, the sealing effect of the battery is influenced.

Description

technical field [0001] The invention relates to the technical field of batteries, in particular to a low-cost battery for electric vehicles and an assembly process thereof.
