For example, if you discharge 8 kWh from a solar battery with a 10 kWh capacity, the battery’s depth of discharge would be 80% (8 kWh / 10 kWh). Depth of discharge is important because it is a signal of a battery’s overall health and lifespan.
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 lifespan of a solar battery decreases each time it is charged and discharged, so the battery will store a smaller amount of energy than when it was new. Batteries will degrade even faster if the DoD limit is exceeded. Leaving batteries partially discharged will also shorten their lifespan.
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. For example, a battery capacity of 500 Ah that is theoretically discharged to its cut-off voltage in 20 hours will have a discharge rate of 500 Ah/20 h = 25 A.
Such applications include residential solar power systems. Fully charged and discharged times C rate provides an easy way to calculate how long a battery can take and discharge fully or reversely. For instance, a C10-rated battery can take 10 hours to discharge fully, while its C rate is rated for a 30-minute discharge.
