By measuring the voltage across the battery, its remaining capacity can be preliminarily estimated. The constant current discharge method is a more accurate battery capacity test method. Connect the battery to a certain load and discharge it at a constant current until the battery voltage drops to the predetermined cut-off voltage.
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).
To estimate battery capacity using a multimeter, follow these steps: Measure the OCV using the multimeter’s voltage setting. Compare the measured voltage with the manufacturer’s voltage vs. state of charge (SOC) chart. Estimate the battery capacity by multiplying the rated capacity by the SOC percentage obtained from the chart.
The standard procedure for conducting a battery capacity test involves charging the battery to its full capacity, then discharging it completely while measuring the amount of energy it produces. The test should be conducted under controlled conditions, with the battery at a specific temperature and discharge rate.
Battery capacity is conventionally measured using units such as ampere-hours (Ah), watt-hours (Wh), or kilowatt hours (kWh), depending on the technology used. Ampere-hours (Ah) measure the total amount of charge that a battery can deliver in one hour.
The reading on the multimeter indicates the instantaneous current being drawn from the battery by the connected load at that moment. This measurement reflects the battery's ability to supply current under the specific conditions of the test, not its total capacity (Ah or mAh).
