Customer ServiceBy 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.
Estimate the remaining capacity: Multiply the SOC by the battery’s rated capacity to estimate the remaining capacity. Let’s assume we have a 12 V, 100 Ah lead-acid battery, and we want to estimate its remaining capacity using the OCV method.
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 State of Charge (SOC) of a battery can be ascertained through a controlled discharge test. The voltage-based method relies on translating the battery voltage reading into an equivalent SOC value using the established discharge curve (voltage vs. SOC) specific to the battery in question.
For professional maintenance personnel, the capacity tester is the preferred tool for measuring battery capacity. By simulating the actual charging and discharging process of the battery, the capacity tester can accurately measure the capacity information of the battery.
