Background technique [0002] Electric double-layer capacitors, as a high-energy-density electrochemical capacitor with a capacity ranging from hundreds to thousands of times higher than traditional electrolytic capacitors, have long service life, good reversibility, high charge and discharge rates, and very low internal resistance (ESR), high cycle efficiency (over 95%), and high output power have been widely used in energy storage technology in recent years with the gradual reduction of production costs. Generally speaking, t...

AI Technical Summary

Problems solved by technology

Generally speaking, the current electric double layer capacitors can be roughly divided into two types in terms of structure. One is the wound type electric double layer capacitor, which is formed by long winding. Although the volume is large, the manufacturing process is relatively Simple, high mass production efficiency, and relatively low cost; the other is a multilayer electric double layer capacitor, although the energy density per unit volume is high, but because it needs to be formed by overlapping and pressing rectangular sheets, the production process is relatively complicated and the cost Relatively expensive, not suitable for large-scale energy storage applications

[0003] At the same time, for the energy storage module composed of capacitor systems, due to the unreasonable distribution of the series and parallel capacitors inside the module or the unreasonable connection method between the modules, the circulation area between the transmission lines is extremely large, and the stray inductance is relatively high, so As a result, power components such as inverters generate peak voltages at the moment they are turned off after they are turned on, resulting in overvoltage damage to the system

Moreover, the stray inductance of the DC link will cause a large voltage drop when the IGBT is turned on

Not only that, but the styles of energy storage modules are also emerging in endlessly. There are great differences between manufacturers and manufacturers. higher secondary cost
