Methods for Measuring Battery Capacity The discharge method involves fully discharging the battery under controlled conditions and measuring the total energy delivered. Ensure the battery is fully charged before beginning the test. Use a resistive load, such as a light bulb or resistor, that matches the battery's rated current draw.
Measure the current: Use a data acquisition system or a microcontroller with an analog-to-digital converter (ADC) to measure the current flowing in and out of the battery. Integrate the current over time: Integrate the measured current over time to obtain the total charge transfer (in Coulombs).
The common units used in battery capacity measurement include ampere-hours (Ah), milliampere-hours (mAh), watt-hours (Wh), and kilowatt-hours (kWh). These units provide essential ways to assess battery capacity, but they also highlight different perspectives regarding the best measurement for specific applications.
Battery capacity testers: Devices that can perform controlled discharge tests, directly measuring capacity in ampere-hours (Ah). Electrochemical impedance spectroscopy (EIS) analyzers: Devices that measure battery impedance to estimate capacity.
In this post we explain what is the battery capacity and what are the main methods to measure it. The capacity of a battery is measured in ampere-hours (Ah). It refers to the amount of energy that can be stored in the battery, and can be determined by multiplying the current (in amps) by the time (in hours) that the battery can supply that current.
