The BSOC is defined as the fraction of the total energy or battery capacity that has been used over the total available from the battery. Battery state of charge (BSOC or SOC) gives the ratio of the amount of energy presently stored. In many types of batteries, the full energy stored in the battery cannot be withdrawn (in other words, the battery cannot be fully discharged) without. A common way of specifying battery capacity is to provide the battery capacity as a function of the time in which it takes to fully discharge the battery (note that in practice the battery often cannot be fully discharged). The notation. In addition to specifying the overall depth of discharge, a battery manufacturer will also typically specify a daily depth of discharge. The daily depth.
