Insulating plate and battery module

Abstract

The invention relates to the technical field of battery modules, and discloses an insulating plate and a battery module. The insulating plate comprises a bottom plate and a cover plate, and the bottomplate is arranged at one end of a battery cell of the battery module; the cover plate and the bottom plate are integrally arranged, a crease is arranged at the joint of the cover plate and the bottomplate, and the cover plate can be folded relative to the bottom plate along the crease and buckled on the bottom plate. The bottom plate and the cover plate are arranged into a whole, the cover plateis arranged to be buckled with the bottom plate through folding, the bottom plate and the cover plate do not need to be connected and fixed together through additional parts, the structure is simplified, the grouping efficiency is improved, the problems of degumming, aging and abnormal sound caused by a gap between the bottom plate and the cover plate are solved. And meanwhile, compared with a bonding connection mode in the prior art, the connection mode that the bottom plate and the cover plate are arranged into a whole is more reliable.

Description

technical field [0001] The invention relates to the technical field of battery modules, in particular to an insulating plate and a battery module. Background technique [0002] The battery module is usually equipped with a blister cover and a blister isolation plate. During assembly, there is no good solution for fixing the blister cover and the blister isolation plate. The existing blister cover and the blister isolation The board is fixed by sticking double-sided adhesive or sticking structural adhesive between the blister cover and the blister insulation board. This fixing method has the following disadvantages: the double-sided adhesive has poor bonding strength, and the It is easy to fail; it is easy to age due to double-sided adhesive bonding; the adhesive structure is difficult to operate, and the amount of glue and the bonding position are difficult to control; the adhesive structure makes it difficult to maintain the battery module, and once the upper cover is opene...

Problems solved by technology

[0002] The battery module is usually equipped with a blister cover and a blister isolation plate. During assembly, there is no good solution for fixing the blister cover and the blister isolation plate. The existing blister cover and the blister isolation The board is fixed by sticking double-sided adhesive or sticking structural adhesive between the blister cover and the blister insulation board. This fixing method has the following disadvantages: the double-sided adhesive has poor bonding strength, and the Easy to fail; sticking with double-sided adhesive, easy to age; the adhesive structure is difficult to operate, the amount of glue and the bonding position are difficult to control; the adhesive structure makes battery module maintenance difficult, and once the upper cover is opened, the battery module structure will be destroyed

[0003] Therefore, there is an urgent need for an insulating board to solve the above problems such as difficult operation, poor connection strength and poor reliability.
