Problems solved by technology

The reasonable expansion space reserved between the single cells of the combination structure will inevitably affect the firmness of the combination, and the heat dissipation and maintainability are poor.
When a single battery in the battery pack is abnormal and needs to be replaced, the combined structure of the overall battery pack must be destroyed, especially when using a large-capacity battery composed of multiple single-battery strings in parallel, it is more prominent in maintainability. Operability is poor

Abstract

The invention relates to a lithium ion single battery modularized combination structure. sleeved at an upper positioning module and a lower positioning module are sleeved correspondingly at the outerside of each single battery, and the upper surface of the upper positioning module is correspondingly provided with a through hole through which a positive electrode column and a negative electrode column of a cell pass; the upper positioning module and the lower positioning module are correspondingly provided with longitudinal fixed clamping grooves at the front and the rear and correspondingly provided with transverse fixed clamping grooves at both sides; the corresponding longitudinal fixed clamping grooves and the transverse fixed clamping grooves are respectively provided with longitudinal positioning columns, transverse positioning columns and positioning baffle blocks with slots. The combination structure design meets the requirements of a storage battery pack on the impact and thevibration and effectively protects a single battery while ensuring the connecting performance of a single battery combination; the storage battery pack can randomly select combination ways of series connection and parallel connection and has simple structure, reliable performance, simple, rapid and flexible operation and convenient maintenance; and the positioning modules reserve certain spaces among the single batteries and meet the requirements of the charging and discharging expansion space of the single batteries and the integral heat dissipation of the storage battery pack.

Description

technical field [0001] The invention relates to a combined structure of a single battery, in particular to a modular combined structure of a lithium ion single battery. Background technique [0002] At present, the battery pack is composed of single cells connected in series and parallel. The main structure of the single cell combination is: the single cells are pasted and fixed with double-sided tape, insulating paper, etc. The reasonable expansion space reserved between the single cells of the combination structure will inevitably affect the firmness of the combination, and the heat dissipation and maintainability are poor. When a single battery in the battery pack is abnormal and needs to be replaced, the combined structure of the overall battery pack must be destroyed, especially when using a large-capacity battery composed of multiple single-battery strings in parallel, it is more prominent in maintainability. Operability is poor. [0003] Therefore, it is one of the ...
