Assembly structure of power battery module

Abstract

The invention provides an assembly structure of a power battery module. The structure comprises an electrical core, an electrical core bearing support, a side tensioning support, a side clamp connection support, an electrical connection support and / or a side tensioning electrical connection support. Through optimization of structural design, the number of an elementary unit consisting of the electrical core bearing support and the electrical core can be flexibly increased or decreased, so that battery modules with different series / parallel connection types can be obtained. Accordingly, the electrical core bearing support is characterized by facilitating assembly of module busbars and mechanical connection with upper and lower electrical core bearing supports. The mechanical parts are connected through screws and interval columns, the module busbars are installed to electrodes located at two ends of the electrical core and are welded to the electrical core, and assembly of an insulated cover is finally completed, thereby forming an integrated power battery module. The problem that the series / parallel connection type of a conventional power battery module cannot be flexibly changed due to limitation by structural members is solved.

Description

Technical field [0001] The invention relates to the technical field of battery modules for electric vehicles, in particular to a power battery module assembly structure. Background technique [0002] With the increasing environmental pollution and the increasing environmental awareness of human beings, the application of new energy electric vehicles has become increasingly widespread, and the development of power battery modules for electric vehicles has become an important topic. At present, electric vehicles usually use multiple single batteries to be placed in the frame of the battery module, and then the batteries are electrically connected through series and parallel modules to form a battery module, which in turn provides energy for the electric vehicle. [0003] The rapid development of new energy electric vehicles has put forward higher requirements for the development speed of battery modules, the mechanical stability of battery modules, and electrical safety. The develop...

Problems solved by technology

At this stage, the development of new battery modules generally needs to go through the stages of design, analysis, proofing, experimental verification, and design optimization. Each stage requires a certain amount of manpower and material resources, which leads to a long development time for new battery modules at this stage. high cost

When new energy vehicles need to develop brand new modules, the above limitations of module development at this stage increase the research and development cycle of the entire new energy vehicle project and increase the research and development cost of the project
