6 FAQs about [Power and battery capacity relationship]

What determines the practical capacity of a battery?

The practical capacity is influenced by many factors, including the discharge rate, the cutoff voltage, the temperature, and the sample history. Finally, the term ‘state of charge’, which is closely linked to the term ‘capacity’, is defined. Angel Kirchev, in Electrochemical Energy Storage for Renewable Sources and Grid Balancing, 2015

What is battery capacity?

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.

How is the theoretical capacity of a battery calculated?

The ‘theoretical capacity’ of a battery is often calculated using Faraday's law of electrolysis; but the ‘practical capacity’ is always less. The practical capacity is influenced by many factors, including the discharge rate, the cutoff voltage, the temperature, and the sample history.

How is power capacity measured in a 2Ah battery?

The way the power capability is measured is in C 's. A C is the Amp-hour capacity divided by 1 hour. So the C of a 2Ah battery is 2A. The amount of current a battery 'likes' to have drawn from it is measured in C. The higher the C the more current you can draw from the battery without exhausting it prematurely.

What is rated capacity of a battery?

The energy that a battery can deliver in the discharge process is called the capacity of the battery. The unit of the capacity is “ampere hour” and is briefly expressed by the letters “Ah.” The label value of the battery is called rated capacity. The capacity of a battery depends on the following factors:

How do you calculate power capacity of a battery?

Power capacity is how much energy is stored in the battery. This power is often expressed in Watt-hours (the symbol Wh). A Watt-hour is the voltage (V) that the battery provides multiplied by how much current (Amps) the battery can provide for some amount of time (generally in hours). Voltage * Amps * hours = Wh.
