Battery module structure

Abstract

The invention discloses a battery module structure. The battery module structure comprises a plurality of single batteries, a pair of side plates, a pair of end plates, a mounting seat, a plurality of electric connecting components and a collecting plate, wherein the single batteries are arrayed to form a battery pack; positive and negative poles of the single batteries are located on top surfaces of the plurality of single batteries; the side plates are respectively fixed on a pair of side surfaces; the end plates are respectively fixed on a pair of end surfaces; the mounting seat is fixed on the top surface, a plurality of through holes are formed in the mounting seat; the electric connecting components include a plurality of first electric connecting components and a plurality of second electric connecting components; each first electric connecting component comprises a protruded part and a pair of flat parts; each second electric connecting component comprises a connecting part and an electrode lead-out end; the flat parts of the first electric connecting components and the connecting parts of the second electric connecting components respectively penetrate through the corresponding through holes and are connected with the poles of the single batteries so as to connect the plurality of single batteries in series; a plurality of collecting terminals and an output terminal are arranged on the collecting plate; and the collecting terminals are connected with the first electric connecting components or the second electric connecting components.

Description

[0001] 【Technical Field】 [0002] The present invention relates to the technical field of batteries, in particular to a battery module structure. [0003] 【Background technique】 [0004] Lithium-ion power battery modules are the core components of electric vehicles, and the stability and reliability of their structure directly affects the performance and life span of the entire battery system. The overall performance of the entire battery module is determined by the worst-performing single battery in the series battery pack. In order to ensure the safety and reliability of the battery module, it is necessary to signal the voltage and temperature of each single battery in the battery module. Collection. At present, most car battery modules use traditional wiring harnesses for data collection. The production efficiency is low and there are problems such as messy arrangement and easy crossover. If only the sampling wiring harness is used, there is a safety hazard of short circuit cause...
