How To Calculate Power Of Battery. Battery capacity is typically measured in Amp-hours Ah or milliamp-hours mAh although Watt-hours Wh is occasionally used. The number of cells chosen for this example is 62 cells which is in between the maximum and minimum limits.
Epack- battery pack energy in watts-hour Wh Ncell- number of battery cells - back. Wh is Watt x hour. How to calculate amp hours.
Calculate the energy content of a Ni-MH battery cell.
You can convert Watt-hours to Amp-hours by dividing by the batterys nominal voltage V as follows. A Watt-hour is the voltage V that the battery provides multiplied by how much current Amps the battery can provide for some amount of time generally in hours. BatteryStuff Tech The draw amount is what we need to calculate with. In this example we will take a standard 12V battery.
