Battery capacity or Energy capacity is the ability of a battery to deliver a certain amount of power over a while. It is measured in kilowatt-hours (product of voltage and ampere-hours). It determines the energy available to the motor and other elements.
The theoretical capacity of a battery is the quantity of electricity involved in the electro-chemical reaction. It is denoted Q and is given by: Q = xnF (6.12.1) (6.12.1) Q = x n F where x = number of moles of reaction, n = number of electrons transferred per mole of reaction and F = Faraday's constant
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:
Typical values of voltage range from 1.2 V for a Ni/Cd battery to 3.7 V for a Li/ion battery. The following graph shows the difference between the theoretical and actual voltages for various battery systems: The discharge curve is a plot of voltage against percentage of capacity discharged.
So scientifically it is denoted as only Ah. For example, the Mahindra e20 has 10kWh energy stored in the battery. It can deliver approx. 208 Ampere current for one hour, at a rated voltage of 48V. How battery capacity affects range? A car’s range depends on its battery’s capacity and efficiency of use.
Energy or Nominal Energy (Wh (for a specific C-rate)) – The “energy capacity” of the battery, the total Watt-hours available when the battery is discharged at a certain discharge current (specified as a C-rate) from 100 percent state-of-charge to the cut-off voltage.

2 · Battery capacity is vital for determining how far an electric vehicle can travel on a single charge. Most battery capacities range from 20 to 100 kilowatt-hours (kWh). A larger capacity generally means more weight, but it also provides increased range. Lifespan is another important attribute of electric car batteries. Most batteries can last between 8 to 15 years, depending on …

in order to normalize against battery capacity, which is often very different between batteries. A C-rate is a measure of the rate at which a battery is discharged relative to its maximum capacity. A 1C rate means that the discharge current will discharge the entire battery in 1 hour. For a battery with a capacity of 100 Amp-hrs, this equates to a discharge current of 100 Amps. A 5C rate for ...
