Supercapacitors, also known as electrochemical capacitors, electric double-layer capacitors, gold capacitors, and farad capacitors, are electrochemical components developed from the 1970s and 1980s that use polarized electrolytes to store energy. This article will tell you the advantages of supercapacitors, its discharge and control time.
Advantages of Super Capacitors:
①Achieving farad-level capacitance in a small volume;
②No special charging circuit and control discharging circuit are required;
③Compared with the battery, overcharging and overdischarging will not have a negative impact on its service life;
④Considering from the perspective of environmental protection, it is a kind of green energy;
⑤Super capacitors can be welded, so there are no problems such as weak battery contact;
Control the Discharge of Supercapacitors:
The resistance of the supercapacitor hinders its rapid discharge. The time constant τ of the supercapacitor is 1~2s, and it takes about 5τ to discharge the resistance-capacitance circuit, that is to say, it takes about 5~10s if the short circuit discharges (due to the special structure of the electrode, it actually takes several hours for them to remove all the remaining charge).
Discharge Control Time:
Supercapacitors can be charged and discharged quickly, and the peak current is only limited by its internal resistance, and is not caused by a short circuit. In fact, it depends on the size of the capacitor monomer. For matching loads, small units can discharge 10A, and large units can discharge 1000A. Another limiting condition of the discharge rate is heat. Repeatedly discharging at a violent rate will increase the temperature of the capacitor and eventually lead to an open circuit.
The above content is the discharge and control time of the supercapacitor. Hopefully the content of this article is helpful to everyone. Dongguan Zhixu Electronic Co., Ltd.
