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. This article will tell you what a super capacitor is and how to calculate the capacitance of a super capacitor!
To put it simply, a super capacitor is a product of ordinary capacitors sacrificing the voltage to increase the capacitance. A single cell of 2.7v has a capacitance of farad level. The instantaneous discharge capacity is super large, so it is called a super capacitor. It is mostly used for car maintenance. After installing a super capacitor, the starting voltage drop is made up by super capacitors, and there will be broad room for development in the future!
Calculation Method of Super Capacitor Capacitance:
The calculation method of the capacitance of supercapacitors is the same as that of ordinary capacitors. When connected in parallel, the total capacitance is equal to the sum of the capacitance of the capacitors, that is, C＝C1＋C2. When connected in series, the calculation is a bit more troublesome. Two capacitors are connected in series, and the total capacitance is: C＝C1* C2/(C1＋C2). Supercapacitors of different capacitance can be connected in parallel, but are not suitable for series connection. It is easy to burn the capacitor when connected in series. The withstand voltage of supercapacitors is relatively low and sensitive to voltage. Generally, the voltage of a single capacitor cannot exceed 2.7V, otherwise the capacitor will be easily broken down and scrapped.
The above content is the calculation method of supercapacitors. Hopefully it’s helpful to everyone. Dongguan Zhixu Electronic Co., Ltd.
