Maximum 30-sec Discharge Pulse Current –The maximum current at which the battery can be discharged for pulses of up to 30 seconds. This limit is usually defined by the battery manufacturer in order to prevent excessive discharge rates that would damage the battery or reduce its capacity.
When a battery is discharged to an extended depth, more energy is released during a single discharge cycle. An increase or decrease in discharge depth, for example, from 2.7 V to 2.5 V, generally has a limited effect on the energy efficiency, as shown in Fig. 9 (c).
The amount of regular charge and discharge cycles, or cycling depth, in addition to the charge level, might affect how quickly capacity fades. Battery degradation affects each battery cell in the battery energy storage system (BESS), which in turn causes capacity fading throughout the system.
In the literature, only a few papers have considered battery aging as a function of the charge/discharge current rate, but they agree that a higher current rate leads to faster battery aging. In any case, all of the tests have been conducted in a climactic chamber with a constant room temperature.
Discharging batteries at different depths can be achieved by using different cutoff voltages. When a battery is discharged to an extended depth, more energy is released during a single discharge cycle.
This can be linked to the relationship between this feature and capacity. The time integral of discharge voltage is proportional to the energy delivered by the battery, since the current is kept constant over the discharge process.
