Problems solved by technology

Most of the existing supercapacitor modules have an overall cuboid structure, with straight upper and lower covers covering the casing, and the monomer is placed inside the casing. The upper and lower ends of the monomer are provided with monomer connecting pieces and insulators. And the upper and lower ends of the monomer and the insulator are compressed to fix the monomer. The heat generated by the monomer is transmitted to the upper and lower covers through the insulator and then naturally cooled in the air. The other part of the heat is transmitted to the outer shell and cooled naturally in the air. The environment is often relatively closed, and it is often difficult to achieve a good heat dissipation effect only by relying on the limited upper and lower covers and the outer surface of the shell. Clamping the supercapacitor monomer, connecting piece and insulator by squeezing the upper and lower covers, although it can play a certain role, However, when the shaking is relatively large, due to the gap between the super capacitor cells, there may still be relative shaking between the cells, which is not good for the use of the module
At the same time, the existing supercapacitor modules often fix the equalization circuit board on the upper surface of the module cover and cover it with a plastic cover to seal it. The module cover has a hole, and the wires on the circuit board pass through the module. The hole opened in the upper cover is connected to the inside, and the circuit board is located between the upper surface of the upper cover and the plastic cover, which can play a certain role in sealing, but when the supercapacitor fails, the sealing effect of the plastic cover is limited, and the internal monomer overflows The electrolyte will overflow through the plastic cover, which is not allowed in use

Description

technical field [0001] The invention relates to a capacitor module and a manufacturing method thereof, in particular to a supercapacitor module and a manufacturing method thereof. Background technique [0002] Supercapacitor is a new type of energy storage device, but because the working voltage of a single supercapacitor is relatively low, it is difficult to be applied in many new energy fields. In order to increase its output voltage and further increase its capacity, it is usually necessary to combine multiple Supercapacitors are connected in series to form a supercapacitor module, thereby increasing its operating voltage and capacity. Due to the advantages of fast charging and discharging speed, high power density and long cycle life, supercapacitor modules are used in many fields such as microgrid, military industry, wind power generation, and new energy vehicles. [0003] Because supercapacitor modules are used in new energy vehicles, wind power and other fields, the ...
