Three Uses of Super Capacitors

Apr. 25, 2022

Supercapacitors are also known as electrochemical capacitors, electric double layer capacitors, gold capacitors, farad capacitors, etc. Different from traditional chemical power sources, supercapacitors are between traditional capacitors and batteries, and power sources with special properties mainly rely on electric double layers and redox pseudocapacitors to store electrical energy. No chemical reaction occurs during the energy storage process, so the supercapacitor can be charged and discharged hundreds of thousands of times.

Because supercapacitors have the characteristics of high power density, wide operating temperature range, fast charging and discharging speed, and long service time, supercapacitors can be used in the following occasions.

(1) Peak output assist

Peak output assist refers to occasions such as camera flashes that need to output large currents instantaneously, and supercapacitors are used to supplement power to the power supply. The use of supercapacitors with high output power is expected to add a high output function of the device and improve the performance of the device to the original miniaturization of the power supply.

Application: LED flash, small DC electrode equipment, smart gas meter, water meter, RKE (remote key), etc.

Three Uses of Super Capacitors

(2) Auxiliary power supply for backup

In the event of a sudden power failure in the equipment, a supercapacitor can be used as a backup power supply. It has the characteristics of long working time, lower ESR than the battery, and miniaturization, which realizes the function of installing in a limited space, high power and high output power.

Application: storage backup such as SSD, PLC, and last gasp of communication equipment.

(3) Reduce battery load

If the load applied to the battery is too large, the voltage of the battery will become unstable, and the supercapacitor can assist the battery to help reduce the load on the battery. Stable operation and improved quality are achieved in communication equipment and audio equipment.

Application: audio equipment, various communication equipment, portable printers, security equipment and medical equipment, etc.

Because supercapacitors have the advantages of large capacitance, wide operating temperature range and long operating time, they are widely used in other industries such as electronic products. When purchasing super capacitors, you should choose a regular manufacturer. Dongguan Zhixu Electronic Co., Ltd.
