How to Measure OCV of Battery: A Step-by-Step Guide
Here is a step by step process to measure the OCV of a battery: First, make sure that the battery is disconnected from any load or charger. It is essential to measure the OCV of the battery when it is in a resting state, i.e., without any current flow. Next, select a high-resolution DC voltmeter to measure the OCV of the battery.
Understanding Battery Capacity: Measurement and Optimization …
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. Create a voltage-SOC curve: We obtain the voltage-SOC curve for our lead-acid battery from the manufacturer''s datasheet. For simplicity, let''s assume the curve is linear and looks like this:OCV (V)SOC …
