Charging and discharging process
A) Charge the module to the rated voltage UR with a constant current I
B) Maintain the rated voltage for 5 minutes
C) Discharge the module to <0.2V with a constant current I
D) U1=80%UR, U2=50%UR
1. Capacity calculation method
C=I*(T2-T1)/(U1-U2),
C: Capacity (F)
I: Discharge current (A)
T2-T1: Discharge time (S)
U1-U2: Voltage change (V)
2. DC ESR (Direct Current Equivalent Series Resistance) measurement method
DC ESR = ΔU / I ,
ΔU: Voltage change over 10ms
I: Discharge current (A)
