If you want to convert between amp-hours and watt-hours or find the C-rate of a battery, give this battery capacity calculator a try. It is a handy tool that helps you understand how much energy is stored in the battery that your smartphone or a drone runs on.
Understanding Energy Storage Capacity: The capacity of an energy storage device is a crucial factor in determining its ability to store energy. It is calculated using the formula C = E / (P * t), where C is the capacity, E is the energy to be stored, P is the power rating of the device, and t is the duration of storage.
When sizing batteries for renewable energy systems, factors such as daily energy consumption, available solar/wind resources, charging and discharging efficiency, depth of discharge, and expected system losses should be taken into account. These factors help determine the battery capacity needed to store and supply energy effectively.
The last thing we need to do is calculate the refrigeration capacity to handle this load, a common approach is to average the total daily cooling load by the run time of the refrigeration unit. For this I''m estimating the unit to run 14 hours per day which is fairly typical for this size and type of store. Therefore our total cooling load of 86.7kWh/day divided by 14

Calculation Formula. The motor capacity in kilowatts (kW) can be calculated using the following formula: [ text{Motor Capacity (kW)} = frac{sqrt{3} times text{Voltage (V)} times text{Current (A)} times text{Power Factor}}{1000} ]
Battery Capacity = Current (in Amperes) × Time (in hours) Battery Capacity represents the total amount of electrical energy a battery can store, typically measured in ampere-hours (Ah) or watt-hours (Wh). Current
Battery Capacity (in Ah) = (I × t) / 3,600 Which is the required formula. There are various factors that affect the battery capacity such as the chemistry of the substances used in the making of the battery to external factors such as temperature. Let’s discuss these factors in detail as follows:
The battery pack capacity C bp [Ah] is calculated as the product between the number of strings N sb [-] and the capacity of the battery cell C bc [Ah]. The total number of cells of the battery pack N cb [-] is calculated as the product between the number of strings N sb [-] and the number of cells in a string N cs [-].
The motor capacity in kilowatts (kW) can be calculated using the following formula: \ [ \text {Motor Capacity (kW)} = \frac {\sqrt {3} \times \text {Voltage (V)} \times \text {Current (A)} \times \text {Power Factor}} {1000} \]
The capacity of electric motors is essential in ensuring the right power is delivered for various industrial and mechanical applications. Historically, the calculation of motor capacity has been key to optimizing power use and efficiency. As industrialization progressed, this calculation became central to electric motor selection and design.
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].
So, let’s start learning about the very important concept of “Battery Capacity”. Battery Capacity is defined as the product of the electric current flowing in or out of the battery in amperes and the time duration expressed in hours. Battery Capacity influences the time for which a device can operate without using power from any other sources.
