Electric Double Layer Capacitors (EDLC) and Supercapacitors

Electric Double Layer Capacitors (EDLC), also known as supercapacitors, are electrochemical capacitors that are used for storing electrical energy. They have a high capacitance and can store between 10 to 100 times more energy than traditional capacitors. As compared to other types of capacitors, they have a much higher power density, as they are able to store much more energy in a smaller package.

The BCAP0003 P270 S01 is a type of EDLC that is designed for use in high-power applications. It has a high capacitance and a low equivalent series resistance (ESR), which allows it to provide high amounts of power quickly. The device has been designed for use in systems that require high peak currents such as electric and hybrid vehicles, pulse power applications and renewable energy storage. The BCAP0003 has a long service life of up to 10 years.

Working Principle

EDLCs store electrical energy like a conventional capacitor, except that the energy is stored mainly in the electric double layer formed at the interfaces of the two electrodes, rather than by dielectric polarization. This double layer is formed by the trapping of ions and electrons between the two electrodes. This means that EDLCs can store more energy than a traditional capacitor, while also being able to discharge it much faster.

The charging and discharging process of an EDLC is controlled by the properties of the electrolyte used, and the power handling capability of the EDLC depends mainly on the capacitance of the electrodes, conducting media, and the ESR of the battery. The BCAP0003 has been designed with a low ESR, which allows it to provide high power quickly.

Application Fields

The main application of EDLCs is energy storage and delivery. They are used for applications that need high peak currents, such as electric and hybrid vehicles, pulse power applications, and renewable energy storage, such as solar and wind power. The BCAP0003 is designed for use in these types of applications.

EDLCs have also found use in other fields such as automotive electronics, medical devices, portable electronic devices and telecommunication systems. They are also used in high-power uninterruptible power supply systems, where their fast charging and discharging capabilities are useful.
