Three Compositions of Supercapacitors
Release time:
2019-11-17
There are three common types of supercapacitors: series, parallel and series-parallel. Supercapacitor assembly in series: Since the single working voltage of the supercapacitor is not high enough to cover the voltage requirement range of the application condition, multiple monomers need to be connected in series to meet the voltage requirement of the application condition. However, due to the inherent differences between the single capacitors, the total voltage acting on the series components cannot be evenly distributed to different capacitors, which will lead to the asymmetry of voltage distribution.

Supercapacitors in parallel: A supercapacitor assembly constructed in parallel can output or receive a large current. In the charging process, the voltage distribution between cells is guaranteed by the series charging resistance. However, the inherent charging resistance of the supercapacitor is a dynamic quantity with certain dispersion, which makes the control circuit to adjust the change of resistance extremely complicated and difficult to realize point-by-point control. In the discharge process, control the discharge resistance, can obtain a high output power, but in order to avoid the discharge current is too large, to ensure the allowable output power, to properly control the energy storage components.
China's wire and cable market has more than 7,000 manufacturers, mainly concentrated in Guangdong, Jiangsu, Hebei, Anhui, Henan, Chongqing, Shandong and other places. In recent years, with the bottleneck problem of energy and power shortage in economic development, China keeps increasing investment in power, which makes the wire and cable industry step into a period of rapid development.
Although the domestic electric wire reading industry has made good achievements recently relying on infrastructure projects such as smart grid construction and rural power grid renovation, the development of the electric wire and cable industry is still subject to great constraints.
