4 FAQs about Can flow batteries be charged and discharged simultaneously

Can a battery be charged and discharged simultaneously?

There is no simultaneous charging and discharging going on. Draw out the circuit and follow the currents. You can conceptualize the above example as 1 A charging the battery and 3 A discharging it, but the battery sees the sum. Again, draw a diagram and it should be more clear. Handwaving makes everything difficult to understand.

Is the battery charging and discharging at the same time?

No, the battery is not charging and discharging at the same time. When the charging system (solar panel or alternator) is below the voltage of the battery, the battery supplies the needed current instead. It can supplement the charge coming from the charging system, but it is not being charged.

Can You charge a battery and power a load at the same time?

Yes, you can charge a battery and power a load at the same time if your solar panel provides more power than the load requires. To do this, place a blocking diode between the solar panel and the battery to prevent the battery from discharging back into the solar panel when it's not receiving sunlight.

What is a flow battery?

Flow batteries allow for independent scaleup of power and capacity specifications since the chemical species are stored outside the cell. The power each cell generates depends on the current density and voltage. Flow batteries have typically been operated at about 50 mA/cm 2, approximately the same as batteries without convection.
