Free QuoteDepth 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.
Depth of discharge (DOD) also has an important impact on battery life. Under different SOC conditions, the battery is discharged at different discharge depths (20 % DOD, 80 % DOD). The best discharge depth can be obtained by studying the battery performance at different discharge depths.
2. Depth of Discharge (DOD) 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 maximum daily depth of discharge may either be set arbitrarily (e.g., a figure of 20–30% is common), or it may be worked out from the known daily cycle, the cycle life of the battery in question and the required lifetime (if cycling is the limiting factor). For seasonal storage (if used) a maximum depth of discharge needs to be set.
Deep discharge depth increases BESS energy consumption, which can ensure immediate revenue, but accelerates battery aging and increases battery aging costs. The proposed BESS management system considers time-of-use tariffs, supply deviations, and demand variability to minimize the total cost while preventing battery aging.
The discharging of a battery is generally limited to 80% of the nominal capacity. For solar applications, the discharge depth hardly exceeds 60%. Accumulators are often oversized in order to increase their lifespan [22, 26]. Rui Xiong, ... Fengchun Sun, in Renewable and Sustainable Energy Reviews, 2020
