    FAQs about Discharge depth of energy storage equipment

    What is depth of discharge (DOD) in energy storage?

    Depth of Discharge (DOD) is another essential parameter in energy storage. It represents the percentage of a battery's total capacity that has been used in a given cycle. For instance, if you discharge a battery from 80% SOC to 70%, the DOD for that cycle is 10%. The higher the DOD, the more energy has been extracted from the battery in that cycle.
