Is it possible to charge and discharge a battery simultaneously for an extended period of time?
I really don`t think it is possible to charge and discharge a battery simultaneously. When a battery is being charged the Voltage drop across it`s internal resistance is of the opposite polarity to what it is when it is being discharged. This is a simple fact that can not be ignored in determining whether or not a battery can be charging and discharging simultaneously. The Voltage drop across the batteries`s internal resistance can not be of two different polarities at the same time. Therefore if the battery is not dormant (no current flow) it either has to be charging or discharging but can not do both at the same time. I realize that it is sometimes convenient and legitimate when doing circuit analysis to consider two different Voltages present across a resistance and then use the net Voltage to determine the current through the resistor. But actually the net Voltage is the only Voltage that is present across any resistor at any given time. The instantaneous polarity of the net Volta
