Are you tired of not knowing how much energy you have left in your batteries? Do you wish you could calculate your energy storage like a mathematician? Well, look no further! We’ve got the formula for you!
The formula for calculating energy storage is as follows:
Energy Stored = Voltage x Capacity
We know, we know, this looks like something out of a calculus nightmare. But don’t worry, we’ll break it down for you.

Categories / Types / Range / Levels of Energy Storage Calculations
When it comes to energy storage calculations, there are different categories/types/range/levels to consider. We’ve even included the imperial system units for those of you who prefer them. The categories include:
- Capacity: This refers to the total charge the battery can hold, and the unit of measurement is Ampere-hours (Ah).
- Voltage: This refers to the pressure of the electrical charge, and the unit of measurement is Volts (V).
- Energy: This refers to the total amount of energy stored in the battery, and the unit of measurement is Watt-hours (Wh).
- Power: This refers to the rate at which energy is being used or produced, and the unit of measurement is Watts (W).
- State of Charge: This refers to how much of the battery’s capacity has been used, and the unit of measurement is a percentage (%).
Examples of Energy Storage Calculations
Let’s dive into the fun part of energy storage calculations! Here are some examples of energy storage calculations for different individuals:
- Joe: Joe’s battery has a capacity of 100 Ah and a voltage of 12 V. To calculate the energy stored, we multiply the capacity by the voltage: 100 Ah x 12 V = 1200 Wh. Joe’s battery has an energy storage of 1200 Wh. The power is calculated by dividing the energy by time (in seconds), and the state of charge is calculated by dividing the current charge by the total capacity and multiplying by 100. Joe’s power is 30 W, and his state of charge is 75%.
- Jane: Jane’s battery has a capacity of 50 Ah and a voltage of 24 V. To calculate the energy stored, we multiply the capacity by the voltage: 50 Ah x 24 V = 1200 Wh. Jane’s battery has an energy storage of 1200 Wh. The power is calculated by dividing the energy by time (in seconds), and the state of charge is calculated by dividing the current charge by the total capacity and multiplying by 100. Jane’s power is 120 W, and her state of charge is 50%.
- John: John’s battery has a capacity of 200 Ah and a voltage of 6 V. To calculate the energy stored, we multiply the capacity by the voltage: 200 Ah x 6 V = 1200 Wh. John’s battery has an energy storage of 1200 Wh. The power is calculated by dividing the energy by time (in seconds), and the state of charge is calculated by dividing the current charge by the total capacity and multiplying by 100. John’s power is 10 W, and his state of charge is 25%.
