So, let’s dive right in and demystify the calculation of battery kWh! Battery kWh, or kilowatt-hour, is a unit of energy commonly used to measure the capacity of a battery. Understanding how to calculate battery kWh is crucial for determining the energy efficiency and performance of batteries.
To calculate battery kWh, we need to convert the battery capacity from ampere-hours (Ah) to watt-hours (Wh). This conversion is necessary because kilowatt-hours (kWh) are commonly used to measure energy consumption. To convert ampere-hours (Ah) to watt-hours (Wh), multiply the battery capacity by the battery voltage.
This will give you the total energy capacity of the battery in watt-hours. Using the battery voltage of 12 volts (V) and the battery capacity of 100 ampere-hours (Ah), the calculation would be as follows: 100 Ah × 12 V = 1,200 Wh (or 1.2 kWh) Therefore, the battery has a capacity of 1,200 watt-hours or 1.2 kilowatt-hours.
