The indicators describing the performance of supercapacitors are:
(1) Rated capacity. Refers to the specified constant current (for example, the charging current specified by the supercapacitor above 1000F is 100A, and the charging current below 200F is 3A). After charging to the rated voltage, it is kept for 2~3min, and discharged to the terminal voltage under the specified constant current discharge condition. The product of the required time and current is divided by the rated voltage value in Farads, F.
(2) Rated voltage. The highest safe terminal voltage that can be used. In addition, there is a surge voltage, usually 105% of the rated voltage; the breakdown voltage is much higher than the rated voltage, about 1.5 to 3 times the rated voltage, in volts (V).
(3) Rated current. Refers to the current discharged to half of the rated voltage within 5s, in amperes (A).
(4) Maximum storage energy. Refers to the energy released by discharging to zero at rated voltage, in joules (J) or watt hours (Wh).
The emergence of supercapacitors solves the contradiction between power density and energy density in energy systems. With the further development of supercapacitor technology, it will gradually replace the batteries that need to be replaced frequently, and the household energy storage system may also be realized. As a kind of energy storage system with huge energy storage, fast charging and discharging speed, wide working temperature range, reliable and safe operation, no maintenance and low price, if it can be widely used in power system, it will promote technological progress and achieve greater Economic benefits.
