3-cell DSF & DGH capacitors provide very fast power discharge that cannot be matched by conventional capacitors or batteries. That large capacity makes it possible to support brief
Supercapacitors, also called ultra capacitors or double layer capacitors, are specially designed capacitors that possess very large values of capacitance—as high as 12,000 F. They can be recharged very quickly and are used primarily for energy storage. Supercapacitor construction and operation. (Image: ES Components.) How do supercapacitors work?
The specific power of supercapacitors far exceeds that of the lithium-ion battery. Since supercapacitors charge and discharge so quickly, they are excellent candidates for energy storage during regenerative braking of hybrid and electric vehicles. Supercapacitors are also being applied to large-scale energy storage in renewable energy applications.
The 47000 µF capacitor bank provides energy storage. An energy storage application and a large capacitance value suggests supercapacitors should be investigated, but because the voltage is so large, series-parallel combinations are necessary.
The rapid charging and discharging of supercapacitors is reflected in their specific power, a parameter with units of watts per gram (W/g). Power is the rate of receiving or delivering energy (p = dW/dt). The specific power of supercapacitors far exceeds that of the lithium-ion battery.
