とができることになる。First, constant current discharge per minute is discharged for 4 minutes at a constant current of 25A, and constant voltage charge per minute (this charge is called charge 1) is performed at a voltage of 14.8V (for a 12V storage battery) and a limited current of 25A ( Charging was performed for 2 minutes at discharge t (same value as current value), and these discharges and charging 1 were alternately repeated 7 times at pt. This was repeated 10 times. Here, if the charging time is shorter than the discharging time, the discharge depth gradually becomes deeper as the charging time is repeated. In other words, do you change the time for discharging or charging 1?
Alternatively, the discharge depth can be changed by changing the number of repetitions.
