WEET Engineers would like to share the advantages of super capacitor:
1. Capacitance up to Faraday level in a very small volume;
2. There is no need for special charging circuit and control discharge circuit;
3. Compared with battery, overcharge and over discharge have no negative effect on battery life;
4. From the perspective of environmental protection, it is a green energy;
5. The super capacitor can be welded, so there is no problem like the battery contact is not firm;
WEET Engineers also are aware of some disadvantages of super capacitor:
1. Electrolyte leakage will be caused by improper use;
2. Compared with aluminum electrolytic capacitor, it has larger internal resistance, so it can not be used in AC circuit;
For the selection of super capacitor, power requirement, discharge time and system voltage change play a decisive role. The output voltage drop of the super capacitor is composed of two parts, one is the energy released by the super capacitor, the other is caused by the internal resistance of the super capacitor. In the very fast pulse, the internal resistance part is the main part, on the contrary, in the long-time discharge, the capacitive part is the main part.
