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.
During the charging period, the system prioritizes charging the battery first from PV, then from the power grid until the cut-off SOC is reached. After reaching the cut-off SOC, the battery will not discharge, and the photovoltaic output will also be normal. During the discharge period, the battery is used for self-consumption.
Energy charged into the battery is added, while energy discharged from the battery is subtracted, to keep a running tally of energy accumulated in the battery, with both adjusted by the single value of measured Efficiency.
The amount of time storage can discharge at its power capacity before exhausting its battery energy storage capacity. For example, a battery with 1MW of power capacity and 6MWh of usable energy capacity will have a storage duration of six hours. Depth of Discharge (DoD) expresses the total amount of capacity that has been used.
A battery energy storage system (BESS) is an electrochemical device that charges (or collects energy) from the grid or a power plant and then discharges that energy at a later time to provide electricity or other grid services when needed.
For example, nickel cadmium batteries should be nearly completely discharged before charging, while lead acid batteries should never be fully discharged. Furthermore, the voltage and current during the charge cycle will be different for each type of battery.
