Series and parallel connection structure and method of supercapacitor module

Abstract

The invention belongs to a series and parallel connection structure and method of a supercapacitor module. The series and parallel connection structure is characterized in that a connector comprises afirst blind hole located in one end of the connector and a second blind hole located in the other end of the connector, the inner diameter of the first blind hole is matched with the outer diametersof one of to-be-connected post terminals of supercapacitor single bodies, and a boss structure top limit is arranged on the end face of the top of the first blind hole and is in interference fit withthe to-be-connected post terminals of the supercapacitor single bodies; a through hole for screw mounting is formed in the central line of a second blind hole and is in interference fit with another to-be-connected post terminal of the supercapacitor single bodies; and toothed locking washers are superimposed on the first blind hole and the second blind hole of the connector correspondingly for pressurization. Heating caused by poor contact in the using process of supercapacitors is relieved greatly, and a series of problems caused by dispersion of voltage values of all the supercapacitor single bodies are solved.

Description

[technical field] [0001] The invention belongs to the field of electrochemical energy storage components, and specifically relates to a series-parallel connection method of supercapacitors, but is not limited to other structures, other energy storage components or device serial-parallel connection methods. [Background technique] [0002] Supercapacitor is a new type of energy storage device, which has the characteristics of fast charging time, high operating temperature range, energy saving and environmental protection, especially the characteristics of high charge and discharge power, and is irreplaceable. Therefore, the series-parallel connection method of supercapacitors directly affects It ensures its high current charge and discharge capability and safe use. [0003] The supercapacitor module is composed of a certain number of electric double-layer supercapacitors or lithium-ion supercapacitors, which are connected by a single simple structural member. Whether it is a t...
