Application Areas of Super Capacitors

Oct. 15, 2021

Supercapacitors are common electronic components. Supercapacitors used to be mainly used for high-power power supplies and large-scale industrial and consumer power supplies. Now they have found their use in products of various sizes, especially portable devices. Supercapacitors are well-known for their up to thousands of farads capacitance values and fast charging and discharging rates. This article wants to talk about the advantages of supercapacitors in various fields.

1) Electronic Consumption

Supercapacitors have the characteristics of being able to quickly complete charging in a short time and provide instantaneous large currents. They can act as a backup power supply in the event of a sudden drop in system voltage. For example, when the main power supply is suddenly interrupted, poor contact, or overloaded, etc., the super capacitor can avoid the adverse effects on the electrical appliances due to the sudden power failure.

2) Transportation

Supercapacitors are mainly used in electric vehicles and hybrid vehicles in transportation. Electric vehicles and hybrid vehicles have high requirements for power energy. The storage battery is limited by its own power output, service life, charging and discharging efficiency, etc., and cannot meet the needs of locomotives to a large extent. The super capacitor-battery pack can improve the startability of the locomotive, to a certain extent, it can well meet the power requirements of the motor vehicle when starting, accelerating, and climbing or just one-time start.

In order to minimize the negative impact of high-current charging and discharging on the battery, the cooperation between the super capacitor and the power battery is required to extend the battery life. At the same time, supercapacitors can also recover instantaneous energy through the regenerative braking system to improve energy utilization.

3) Renewable Energy Power Generation/Distributed Power System

Supercapacitors have the characteristics of high specific power, long service life, high energy storage efficiency, and maintenance-free. In the field of renewable energy power generation or distributed power systems, they can make up for the instability and unpredictability of the output power of power generation equipment. In high-voltage switch stations and silicon rectifier opening and closing devices in substations, since super capacitors can effectively solve the problems of poor reliability of opening and closing devices caused by low energy storage and large leakage current of traditional electrolytic capacitors, traditional electrolytic capacitors are gradually being replaced by super capacitors.

Application Areas of Super Capacitors

Super capacitors can also be applied to distributed power grids. The distributed grid system uses multiple sets of super capacitors to store energy in the form of electric field energy. When energy is in short supply, the stored energy is released through the control unit, which can accurately and quickly compensate for the energy required by the system to achieve electrical stable control of the balance mechanism. At the same time, super capacitors can also improve the quality of the power grid.
