Q: What are the main applications of supercapacitors?
A: The two main applications of supercapacitors: high-power pulse applications and instantaneous power retention. The characteristics of high-power pulse applications: instantaneous flow of large current to the load; characteristics of instantaneous power retention applications: it requires continuous supply of power to the load, and the duration is generally a few seconds or a few minutes. A typical application of instantaneous power retention: the reset of the disk drive head when the power is off.
Q: Why is the internal resistance of supercapacitors important?
A: A large part of the reason why super capacitors can be widely used is that they have the advantages of high power density and short charging time. This is due to the fact that super capacitors do not undergo chemical reactions during the energy storage process, and only electron migration occurs. So the internal resistance of super capacitors is only affected by the ohmic internal resistance. For this reason, the internal resistance is an important performance parameter of the supercapacitor, and the accuracy of the internal resistance test is an important indicator for evaluating the capacitance.
