Understanding kWh is crucial for optimizing energy storage. Battery capacity, voltage, current, and time are fundamental in kWh calculations. Different battery types require specific approaches for accurate kWh determination. Factors like temperature and depth of discharge influence kWh calculations.
This we can do using the following steps: Determine the kWh requirements of the device. Divide the battery kWh with the device kWh. Using the kWh = Ah X V / 1000 equation, we can calculate the total battery capacity. Here we have to pay attention to something called the battery discharge curve.
Efficiency is the sum of energy discharged from the battery divided by sum of energy charged into the battery (i.e., kWh in/kWh out). This must be summed over a time duration of many cycles so that initial and final states of charge become less important in the calculation of the value.
The maximum amount of energy accumulated in the battery within the analysis period is the Demonstrated Capacity (kWh or MWh of storage exercised). In order to normalize and interpret results, Efficiency can be compared to rated efficiency and Demonstrated Capacity can be divided by rated capacity for a normalized Capacity Ratio.
As you might remember from our article on Ohm's law, the power P of an electrical device is equal to voltage V multiplied by current I: As energy E is power P multiplied by time T, all we have to do to find the energy stored in a battery is to multiply both sides of the equation by time:
The energy storage capacity, E, is calculated using the efficiency calculated above to represent energy losses in the BESS itself. This is an approximation since actual battery efficiency will depend on operating parameters such as charge/discharge rate (Amps) and temperature.
The total battery volume is computed based on the operation’s one-year mission profile. Based on the BESS sizing, the oversizing factor of power and energy is derived, for calculating the error in BESS sizing due to the approximation of the number of strings of batteries and batteries in series.
