State Of Charge (SOC) is the battery's level of charge, usually expressed as a percentage of full. It is similar to a fuel gauge, such that 25% SOC is 1/4 full. Depth Of Discharge (DOD) is another term used which describes how empty the battery is. DOD is the opposite of SOC. So, 25% SOC is equal to 75% DOD. Since in a Hybrid car the battery is recharged from gas, the SOC usually has a target of about 3/4 full. This is unlike a Battery electric vehicle (BEV) whose SOC would fall from full to empty untill refueled like a traditional gas car.

State Of Charge Drift as demonstrated by the Rons PriusPlus and also known by Insight drivers as a Recalibration event is the manifestation of voltage based correction in primarily counter based SOC calculation algorithms. It can be taken advantage of in PHEV conversions enable State Of Charge Manipulation which can help improve battery pack utilization.
