    Battery Depth of Discharge, frequently abbreviated as DoD, is a technical metric that quantifies the extent to which a battery's stored energy has been expended.


    FAQs about Discharge depth of energy storage

    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.

    What is the difference between depth of discharge and state of charge?

    Depth of discharge (DoD) indicates the percentage of the battery that has been discharged relative to the overall capacity of the battery. State of charge (SoC) indicates the amount of battery capacity still stored and available for use. A battery's "cyclic life" is the number of charge/discharge cycles in its useful life.

    How does depth of discharge affect battery life?
