Battery SOC: How Do We Estimate "State Of Charge" Of Batteries?

Another closely related term to SOC is Depth of Discharge (DOD). It''s actually just the inverse of SOC, i.e., it''s an alternate method to indicate how much of a battery''s charge has been used up. A battery holds charge, and we want to measure how much it holds at a given instant. In other words, we want to determine its State of Charge.
