No, you cannot charge and discharge a battery simultaneously. Draw the currents going into and out of the battery terminals between the charger and the load: If the charger is pumping 1A into the battery to charge it and the
No, a battery cannot be charged and discharged simultaneously. There is no simultaneous charging and discharging going on. You can conceptualize this as 1 A charging the battery and 3 A discharging it, but the battery sees the sum. Drawing a diagram should make it clearer.
The initial SOC value of each cell, considered for the discharging test is more than 50% thus the charge/discharge controller switched to discharging mode and started discharging the LIB pack with a constant discharging current of 4A.
