To calculate amp hours, you need to know the voltage of the battery and the amount of energy stored in the battery. Multiply the energy in watt-hours by voltage in volts, and you will obtain amp hours. Alternatively, if you have the capacity in mAh and you want to make a battery Ah calculation, simply use the equation: Ah = (capacity in mAh)/1000.
The required battery pack total energy E bp [Wh] is calculated as the product between the average energy consumption E avg [Wh/km] and vehicle range D v [km]. For this example we’ll design the high voltage battery pack for a vehicle range of 250 km. The following calculations are going to be performed for each cell type.
Amount of charge the battery can store, determining how long it can power a device. Larger capacities mean longer run times. Common consumer batteries range from 2,000mAh to 100Ah or more for industrial use. Total energy the battery holds, calculated as capacity in Ah multiplied by voltage. Important for understanding total energy in the battery.
or, hours of use (h) equals to Kilowatt-hour capacity of the battery (kWh) divided by the Kilowatt requirement of the device (kW). There is something else to consider, concerning the type of battery used. There is a general distinction between two kinds of batteries, made from two different materials: Lead-acid and Lithium-ion.
The discharge current represents the rate at which the battery is discharged. To calculate it, use the formula: Discharge Current (I) = Rated Capacity (C) / Discharge Time (t) For example, if a battery has a rated capacity of 100 Ah and will be discharged over 10 hours, the discharge current would be: I = 100 Ah / 10 hours = 10 A
The energy content of a string E bs [Wh] is equal with the product between the number of battery cells connected in series N cs [-] and the energy of a battery cell E bc [Wh]. The total number of strings of the battery pack N sb [-] is calculated by dividing the battery pack total energy E bp [Wh] to the energy content of a string E bs [Wh].
