Power Electronics and Energy

They have two types, High Power Density for a large current discharge. High Energy Density for a long backup time. Over a million Charge/Discharge cycles. High Efficiency. Capable of fully discharging to zero volts.

EverCAP - Double Layer Capacitors - Nichicon



Some things to note for a design engineer. The EDLC or Electric Double Layer Capacitors ...

• Note Specified Endurance and end of life.
• Excess Vibration can alter Specs, Damage.
• Caution - Never Exceed Maximum temperature.
• Specs are very dependent on Temperature.

These EDLC supercap have one-tenth of energy, but delivers over 10 times of power due to ultra low ESR. In Comparison with a Battery. A Lifetime of over 500,000 cycles.

Hy-Cap EDLC Single cell - Vinatech

Hy-Cap is an energy storage device that stores instantly a  large volume of electric energy and supplies instantly or  continuously higher current, by the mechanism of  absorbing and de-absorbing electric charge.



Hy-Cap EDLC single cell models use activated carbon on the anode  and cathode electrodes. These models come in lead terminal,snap-in terminal and axial terminal variants.

They have a range of Supercapacitors upto 2500F at 2.5V and Modules like 400F at 15V. There are two types Prismatic and Cylindrical. In comparison to batteries, multi-million cycles of charge-discharge is possible.

DLCAP - Electric Double Layer Capacitor - Nippon



Another feature is the high current charge-discharge ability, useful in many Industrial and Automotive Applications. A high charge-discharge efficiency makes an output efficiency of around 95% possible. These capacitors have become an useful part of Alternative Energy Electronics and Energy Harvesting. They also have applications in Electric and Hybrid Vehicles.
