SOC - State of charge (SoC) is the level of percentage (0% = empty; 100% = full). SoC in use, while DoD is most often seen when. percentage of the battery that has Depth of Discharge is defined as the battery nominal capacity. capacity. The units of SoC are a discussing the current state of a battery of the battery after repeated use.
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.
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. To envision this concept, picture a fully charged battery as analogous to a reservoir brimming with water.
Depth of Discharge, or battery DoD, is more than technical jargon; it fundamentally influences the efficacy and financial yield of your battery investment. We’ll explore the DoD’s impact on battery longevity and operational performance, helping you optimize your battery systems for maximum DoD and overall capacity of the battery.
Conversely, the SoC stands at 60%, representing the remaining 60 liters or 60% of energy still retained in the storage system. Within this framework, the battery’s capacity (illustrated as 100 liters) is the pinnacle of energy storage capacity of the battery.
Efficiency is the sum of energy discharged from the battery divided by sum of energy charged into the battery (i.e., kWh in/kWh out). This must be summed over a time duration of many cycles so that initial and final states of charge become less important in the calculation of the value.
The Depth of Discharge provides a metric, denoting the percentage of energy that has been drained from the battery. A higher DoD percentage indicates a more substantial depletion of the battery’s total capacity.
