Battery pack and disassembling method thereof

Abstract

The invention discloses a battery pack and a disassembling method thereof, the battery pack comprises a box body, a battery module and a self-heating bonding assembly, and the box body is provided with an accommodating cavity; the battery module is arranged in the accommodating cavity and comprises at least one battery cell; the self-heating bonding assembly comprises a heating layer, the heating layer is powered by the battery module, and the battery module is bonded and fixed in the containing cavity through the self-heating bonding assembly. According to the invention, the current high-integration battery can be disassembled in a lossless manner, the thermal runaway of the battery pack is prevented from spreading, and the residual electric quantity of the battery pack is fully utilized, so that the energy waste is reduced, and the disassembling difficulty of the battery pack can be reduced.

Description

technical field [0001] The invention relates to the technical field of electric vehicle batteries, in particular to a battery pack and a dismantling method thereof. Background technique [0002] With the global energy crisis and environmental pollution becoming more and more serious, electric vehicles are developing rapidly. Electric vehicles use electricity as the power source, and a large amount of fossil fuel can be saved by replacing the fuel engine with an electric motor. With the increasing maturity and development of electric vehicle power battery technology, electric vehicles will surely become the main trend of the future development of the automobile industry. [0003] With the continuous improvement of system integration, the use of adhesive technology has become a trend. The application of adhesive technology has greatly improved the energy density of battery packs. However, the disadvantage of adhesive technology is that it is difficult to disassemble without d...

Problems solved by technology

[0003] With the continuous improvement of system integration, the use of adhesive technology has become a trend. The application of adhesive technology has greatly improved the energy density of battery packs. However, the disadvantage of adhesive technology is that it is difficult to disassemble without damage, which limits The current regulations stipulate that battery packs must be reused and recycled. Simple violent disassembly cannot maximize the value of the battery and does not meet the requirements of environmental protection. Therefore, How to disassemble the battery pack of the viscose solution without damage is a problem that needs to be solved

[0004] At the same time, when the battery pack is being disassembled, it is necessary to release the remaining power of the battery pack to avoid the risk of fire during the dismantling process. The current method used is to directly release the remaining power through the power distribution cabinet, which will cause energy waste and is reasonable The use of this part of the energy is also a problem that needs to be considered
