The most common measure of battery capacity is Ah, defined as the number of hours for which a battery can provide a current equal to the discharge rate at the nominal voltage of the battery. The unit of Ah is commonly used when working with battery systems as the battery voltage will vary throughout the charging or discharging cycle.
The energy stored in a battery, called the battery capacity, is measured in either watt-hours (Wh), kilowatt-hours (kWh), or ampere-hours (Ahr). The most common measure of battery capacity is Ah, defined as the number of hours for which a battery can provide a current equal to the discharge rate at the nominal voltage of the battery.
A larger battery size increases the energy consumption for all users, but only the long-distance driver benefits from a substantial decrease in en-route charging stops. Using a 116-kWh battery instead of a 28-kWh battery increases energy consumption between 13.4% and 16.9% for the three driver types.
The presented energy consumption and power demand maps in Sub-section 2.2 of the methodology are developed for a 300-kWh battery. However, the battery size impacts the propulsion system energy consumption ( Fig. 2) due to its weight, which varies as function of the battery energy capacity.
In relative terms, the urban commuter experiences the biggest increase in emissions when doubling the battery size (20%). This is due to the more frequent and shorter trips of this user type, which requires more frequent cooling or heating of the cabin and battery and thereby increases the energy consumption of the thermal management system.
In order to calculate the size of the battery we need two main inputs: the average energy consumption and the range of the vehicle. This article is explaining how to calculate the energy consumption of a vehicle and it’s part of a EV design series:
Battery Power Consumption Calculator
All you need to do is enter the voltage and capacity of your planned battery pack as well as your average power consumption to calculate the battery life. To meet the needs of different users, we have created a fully off-grid battery power consumption calculator and a partially off-grid battery power consumption calculator.

How Do Capacity and Voltage Affect Battery Performance?
The higher the capacity, the longer a battery can power a device. For example, a battery with a 100Ah capacity can theoretically supply 100 amps for one hour or 10 amps for ten hours. However, real-world performance may vary depending on the application, environmental conditions, and depth of discharge (DoD). Deep discharges reduce the overall lifespan of a …
