Assembled battery box and assembling method thereof

Abstract

The invention provides an assembled battery box. The assembled battery box comprises a bottom plate, a top plate, a first sealing ring, a second sealing ring, a left side plate, a right side plate, afront side plate and a rear side plate; the front side plate and the rear side plate are close to anode and cathode of a module respectively; the first sealing ring is arranged between the bottom plate and the side plates, and the second sealing ring is arranged between the side plates and the top plate; the bottom plate is fixed to the left side plate and the right side plate through bolts. The bottom plate is fixed to the front side plate and the rear side plate through bolts or in a welded mode, the top plate is fixed to the left side plate, the right side plate, the front side plate and the rear side plate through bolts, and the two sides of each of the left side plate and the right side plate are fixed to the front side plate and the rear side plate through bolts or screws respectively. The invention also provides an assembling method of the assembled battery box. Due to the split type design, transportation and storage are convenient, assembly is convenient, installation is easy,the problems of short circuit and the like caused by contact between the anode and cathode of the module and the inner wall of the box in the assembly process are solved, and safety in the operationprocess is guaranteed.

Description

technical field [0001] The invention relates to the field of battery boxes, in particular to an assembled battery box and an assembly method thereof. Background technique [0002] When the current lithium-ion battery is assembled, the box body containing the lithium-ion battery is generally installed first, and then the lithium-ion battery is assembled into the box body, so the following problems are prone to occur: 1) the positive and negative electrodes of the module are not connected to the box body. The inner wall of the body is very close. During the assembly operation, it is easy to cause problems such as short circuit between the positive and negative electrodes of the module and the inner wall of the box, which will cause danger; There is a problem of inconvenient operation when assembling the ion battery; 3) Screws and bolts are easily dropped into the box and are not easy to take out. Contents of the invention [0003] In view of the defects in the prior art, th...
