Battery systems are rated in terms of their energy storage capacity, typically in kilowatt-hours (kWh). You should select a battery system that has enough storage capacity to meet your total load. For example, if your total load is 48,000 watt-hours, you should select a battery system with a storage capacity of at least 48 kWh.
Calculate the capacity of the BESS: To calculate the capacity of the BESS, simply multiply the rated energy of the battery by the DOD: Capacity (kWh) = Rated Energy (kWh) * Depth of Discharge (%) For example, if the battery has a rated energy of 100 kWh and a DOD of 80%: Capacity (kWh) = 100 kWh * 0.80 = 80 kWh.
The formula for determining the energy capacity of a lithium battery is: Energy Capacity (Wh) = Voltage (V) x Amp-Hours (Ah) For example, if a lithium battery has a voltage of 11.1V and an amp-hour rating of 3,500mAh, its energy capacity would be: Energy Capacity (Wh) = 11.1V x 3.5Ah = 38.85Wh.
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
