Customer ServiceBattery state of charge (BSOC or SOC) gives the ratio of the amount of energy presently stored in the battery to the nominal rated capacity. For example, for a battery at 80% SOC and with a 500 Ah capacity, the energy stored in the battery is 400 Ah.
Customer ServiceDepth 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.
However, it is more common to specify the charging/discharging rate by determining the amount of time it takes to fully discharge the battery. In this case, the discharge rate is given by the battery capacity (in Ah) divided by the number of hours it takes to charge/discharge the battery.
The charging/discharge rate may be specified directly by giving the current - for example, a battery may be charged/discharged at 10 A. However, it is more common to specify the charging/discharging rate by determining the amount of time it takes to fully discharge the battery.
The other way round stored electric charge of a battery can be expressed by using the SOC value: (6) q (S O C) = S O C · C Since the value of capacity changes during lifetime due to battery aging, an index of SOC can specify the capacity C, which is the reference for SOC value.
