Problems solved by technology

However, when the cells are closely arranged to form a battery module, due to the electrical connection and mechanical contact between the cells, when an extreme condition occurs in a cell, such as overheating, exhaust or fire, the discharged heat will affect the adjacent cells. cells, so that adjacent cells also experience thermal runaway

Abstract

The invention discloses a thermal insulation structure and a battery module, and belongs to the technical field of batteries. The thermal insulation structure comprises a foamed silica gel pad, and the outer surface of the foamed silica gel pad is provided with a closed structure for closing air holes in the outer surface to form a closed air cavity. According to a heat insulation structure provided in the invention, air is sealed in the sealed air cavity, the heat conductivity of air is poor, the heat conductivity coefficient of foamed silica gel is relatively low, and the foamed silica gel has good electrical insulation performance and good flame retardant property, so that a good heat insulation effect can be achieved, the situation that the adjacent battery cells are out of control dueto the fact that more heat is transferred to the adjacent battery cells when a certain battery cell is overheated, short-circuited, on-fire and the like is avoided, and the safety performance of thebattery module is improved. The battery module provided by the invention is provided with the heat insulation structure, so that more heat can be prevented from being transferred to the adjacent battery cells when a certain battery cell is overheated, short-circuited, on-fire and the like, and the safety performance is improved.

Description

technical field [0001] The invention relates to the technical field of batteries, in particular to a heat insulation structure and a battery module. Background technique [0002] With the rise of new energy vehicles, power batteries have also ushered in a period of rapid development. The safety and stability of new energy vehicles has always been the focus of attention. Therefore, improving the safety of new energy vehicles will be one of the important factors that determine whether new energy vehicles can be popularized rapidly. Battery modules are the main components of battery packs for new energy vehicles, and improving the safety of battery modules is an important way to improve the safety of new energy vehicles. [0003] A battery module is generally composed of a number of cells connected in series or in parallel through conductive sheets, while the module frame surrounds the cells and provides a fixing device for the module. When used as a single cell, since the c...
