Power battery bunching module structure of electric automobile

Abstract

The invention relates to a power battery bunching module structure of an electric automobile. An bunching module assembly comprises a plurality of sub modules, wherein each sub module is provided with an insulation shielding shell in a wrapping mode; a box cap is provided with a detecting unit which is internally provided with a plurality of internal elements correspondingly connected with the sub modules; the internal elements are connected with the sub modules by leads. The power battery bunching module structure is simple in structure, and is novel and reasonable in design; not only can the parallel combination of monomer batteries and the sub modules in the modules be realized, but also the serial combination of the sub modules in the modules can also been realized; an installation technology is simple; the connection is convenient; each sub module can be convenient to detect, maintain, replace and the like; the battery loss can be reduced effectively; the use effect is good; the insulation protective cover on the box cap and fuses can effectively prevent short circuits of circuits and electric shock to maintaining personnel; the safety of the power battery is improved; the safety hazard caused by collision, short circuit, overcharging and overdischarging can be prevented effectively; the power battery bunching module structure of an electric automobile has the relatively wide application range, and the relatively good social prospect and market popularization value.

Description

technical field [0001] The invention relates to the field of electric vehicle power batteries, in particular to an electric vehicle power battery group module structure with simple structure, reasonable design, convenient maintenance and low maintenance cost. Background technique [0002] In view of the consideration of energy saving, emission reduction and environmental protection, electric vehicles are gradually replacing ordinary fuel vehicles driven by internal combustion engines, and electric vehicles powered by batteries are the mainstream direction of current research. Most of the battery modules of existing electric vehicles adopt the connection mode without sub-modules in the module. No matter whether all the single cells are connected in parallel or the single cells are connected in series, it is difficult to disassemble. The fault point is subdivided into the interior of the battery module, which is only suitable for replacing the whole module. It is difficult to ...

Problems solved by technology

Most of the battery modules of existing electric vehicles adopt the connection mode without sub-modules in the module. No matter whether all the single cells are connected in parallel or the single cells are connected in series, it is difficult to disassemble. The fault point is subdivided into the interior of the battery module, which is only suitable for replacing the module as a whole. It is difficult to perform daily maintenance, and the maintenance cost remains high, making it difficult to centralize management and unified recovery of batteries, and waste batteries are easy to lose and cause pollution.
