Supercapacitor module set structure

Abstract

The invention relates to a supercapacitor module set structure. The supercapacitor module set structure comprises a plurality of parallelly-arranged supercapacitor units, two laminated busbars respectively fixed at two ends of the supercapacitor units, and a monitoring protection circuit which is used for protecting all supercapacitor units in a monitoring module set; the laminated busbar comprises at least one multiple-layer-stacked and integrally-molded busbar layer, a frame layer, a plurality of insulating film layers and monitoring protection circuit lead-out lines. The laminated busbar ofthe supercapacitor module set structure is integrally molded, and therefore, cumbersome manual operation during on-site installation can be avoided, technical problems such as complicated structure,inconvenient installation and poor heat dissipation of an existing supercapacitor module set can be solved. The supercapacitor module set structure of the invention has the advantages of simple overall structure, convenient installation, excellent heat dissipation and the like.

Description

technical field [0001] The invention relates to the field of supercapacitors, in particular to a supercapacitor module structure. Background technique [0002] The functions of each module inside the traditional supercapacitor module are separated, and the structure is complex. The shell and the cover module play the role of installation and fixation. The internal cells are connected in series by busbars. The voltage equalization and protection unit is connected between the two terminals of the supercapacitor cells. The voltage monitoring unit is drawn out from the top of the module. The connected supercapacitor bank is assembled into the shell, and a layer of insulating material is arranged between the shell and the capacitor bank to electrically isolate the combined shell of the capacitor. It has the disadvantages of the following aspects: [0003] 1. The supercapacitor module adopts a step-by-step installation method. First install the busbar between the monomers, then ...

AI Technical Summary

Problems solved by technology

This installation method is very cumbersome, and manual operations are required for multiple positions, which is prone to errors

[0004] 2. Every two strings of supercapacitor monomers share a voltage equalization protection unit, and each voltage equalization protection unit is integrated into a PCB board. The voltage equalization protection unit needs to be installed on the terminals of the capacitor monomer after the series welding of the monomers is completed. , the circuit structure is complicated, and the installation is inconvenient

[0005] 3. The heat generated by the supercapacitor is transferred to the shell through the air between the busbar and the shell. This heat transfer method has poor thermal conductivity, and the product temperature rises, posing safety hazards.
