Product introduction:

Electrochemical capacitor (EC), also known as Ultracapacitor and Supercapacitor. It is a new energy storage device between capacitor and battery. Compared with traditional capacitors, electrochemical capacitors have higher specific capacity. Compared with battery, it has the advantages of higher specific power, instant release of large current, short charging time, high charging efficiency, long cycle life, no memory effect and basically maintenance-free. Therefore, it has great potential application value in mobile communication, consumer electronics, electric vehicles, aerospace and other fields.

2 Measurement method

◎ The DC voltage of the constant current/constant voltage source is set to the rated voltage (UR ) .

◎ Set the constant current value of the constant current charging and discharging device specified in Table 1.

◎ Switch the switch S to the DC power supply, and charge it with constant voltage for 30 minutes after the constant current/constant voltage source reaches the rated voltage.

◎ After charging, switch the switch S to a constant current discharge device to discharge with a constant current.

◎ Measure the time t1 and t2 of the voltage across the capacitor from U1 to U2, as shown in Figure 2, and calculate the capacitance value according to the following equation :
