As everyone who has used a supercapacitor knows, in addition to the characteristics of large energy storage, another feature of the supercapacitor is that its charging time is very fast. Generally, it depends on the capacity. It can almost complete the charging of more than 95% within 10 seconds to 10 minutes, which is precisely the reason why the charging time of the electric word is compared with that of the supercapacitor.

So what is the principle of super capacitor charging fast? The supercapacitor itself is an electric double-layer capacitor. It not only has the characteristics of rapid charge and discharge of the capacitor, but also has the characteristics of large capacity of the battery. Therefore, the reason for the simple realization of rapid charge and discharge of the supercapacitor is its structural setting. For the traditional capacitor, the electrode material of the supercapacitor is activated carbon, The internal resistance of this kind of electrode material is much lower than that of traditional capacitors and batteries. The speed is very fast in the process of charging and discharging. If the excessive protection is not set inside the capacitor, the speed will be faster. Generally, the charging is completed quickly in the front moment, and the speed will slow down after reaching a certain rated amount.

The characteristics of fast charging and discharging of supercapacitors have been adopted by new buses. As long as there is no condition on the specific road and the distance, it can basically be charged and formed. For example, supercapacitors have recently been paid attention to the development of supercapacitor mobile phone batteries, so that the charging speed can be faster than the current fast charging speed, But it has not been officially launched yet. The good news is that the process of R & D is still continuing.
