Advantages of Farad Capacitors

Farad capacitors have long service life. Farad capacitors are different from ordinary batteries. It is an electrochemical element. It does not produce chemical reactions during storage. Farad capacitors can reach farad-level capacity in a small volume without special charging and discharging. , is a green and environmentally friendly product. Compared with batteries, farad capacitors can transmit energy repeatedly without reducing the service life like ordinary batteries. Farad capacitors have a relatively long life, and the number of charge and discharge is 500 times that of a pass-through battery, and the cycle is strong. Farad capacitors have no harmful chemicals, no pollution, environmental protection, and are suitable for export enterprises. The withstand voltage of supercapacitors is generally low as long as 2.5V allows the surge voltage to be 2.7V. Therefore, for a singlesupercapacitor , the output voltage of the charger cannot exceed 2.7V. As long as the operating voltage of the supercapacitor is within the safe voltage, the service life of the supercapacitor is very long, and the number of cycles of charge and discharge can reach 10-50 10,000 times.

It is precisely because the operating voltage of supercapacitors is low that it is often necessary to use several supercapacitors in series to increase the operating voltage. Due to the unbalance of supercapacitors, it is necessary to ensure that the charging voltage of any supercapacitor shall not be higher than 2.5 when using in series. V, the solution is to use a battery equalizer.

Farad capacitors have two main purposes: the use of high-power pulses and the maintenance of instantaneous power. The advantages of high-power pulse use: more power flows to the load in a short period of time; the advantages of instantaneous power maintenance use: it is required to continuously increase the power like the load, and the holding time is generally more than ten seconds or a few minutes. One basic use of short-term power retention is the reset of the disk drive head when power is lost. Different machines have different parameter requirements for Farad capacitors. The use of high-power pulses is to use the small internal resistance of the Farad capacitor, and the short-term power persistence is to use the large electrostatic capacity of the ultra-capacitor.

The power density of supercapacitors is dozens of times that of ordinary lithium batteries, and the circuit requirements for charging are not high, saving charging and discharging time. Supercapacitors can be charged and discharged more than 500,000 times. If they are charged and discharged 20 times a day, they can be used continuously for 68 years. The service life is greatly extended. In addition, supercapacitors can be connected in series to form capacitor banks, which can add greater storage capacity.
