                     Figure 1 - Constant Current Discharge Method Circuit


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 :

C capacity (F);

I discharge current (A);

U1  measures the initial voltage (V) ;

U 2  measures the termination voltage (V);

t 1  Time (s) for the discharge voltage to reach U1;

t 2   Time (s) for the discharge voltage to reach U2.

See Table 1 for the discharge current I and the voltages U1 and U2 at which the discharge voltage drops .

in

Ra AC internal resistance (Ω);

U RMS value of AC voltage (V rms);

I AC current rms value (V rms).

The frequency at which the voltage is measured, should be 1kHz.

The AC current should be 1mA to 10mA.
