Supercapacitors, also known as electrochemical capacitors, electric double-layer capacitors, gold capacitors, and farad capacitors, are electrochemical components developed from the 1970s and 1980s that use polarized electrolytes to store energy.
Miniature supercapacitors have been widely used in small mechanical equipment, such as computer memory systems, cameras, audio equipment, and auxiliary facilities for intermittent use of electricity. Large-size cylindrical supercapacitors are mostly used in the automotive field and natural energy harvesting. How to calculate the capacitance of supercapacitors? Let’s read this article to learn more.
The capacity calculation method of super capacitor:
The capacity calculation method of supercapacitors is the same as that of ordinary capacitors. When connected in parallel, the total capacity is equal to the sum of the capacities of the capacitors, that is, C=C1+C2. When connected in series, the calculation is a little troublesome. When two capacitors are connected in series, the total capacitance is: C=C1*C2/(C1＋C2). Supercapacitors of different capacities can be connected in parallel, but are not suitable for series connection. It is easy to ruin the capacitor when connected in series. The withstand voltage of supercapacitors is relatively low and they are sensitive to voltage. Generally, the voltage of a single super capacitor cannot exceed 2.7V, otherwise the capacitor will be easily broken down and scrapped.
The capacitance calculation method of the super capacitor is as mentioned above. It should be noted that the super capacitor can be connected in parallel, but it is not suitable for connecting in series. Before using it, you need to understand the actual situation of the circuit to avoid unnecessary trouble. When purchasing supercapacitors, you need to find some reliable manufacturers.
