This behaviour causes fluctuations in the system's voltage, hampering the voltage regulation process. Battery energy storage systems (BESSs) are normally installed in power systems to mitigate the effects of these fluctuations and to control the voltage and frequency of the system [ 1 - 3 ].
(Recommended) Charge Current – The ideal current at which the battery is initially charged (to roughly 70 percent SOC) under constant charging scheme before transitioning into constant voltage charging. (Maximum) Internal Resistance – The resistance within the battery, generally different for charging and discharging.
When charging at a constant voltage, the battery's voltage is maintained as the charging current gradually decreases towards zero as the battery nears full charge. By controlling the voltage between the battery terminals, this method protects the battery from being overcharged.
Constant-current charging entails sending a constant current to the battery during the charging process. The charging rate remains constant as the battery voltage increases. When the battery voltage is low, this method is frequently utilized in the early stages of charging. ii.
Charge Efficiency: This measure represents the proportion of energy that a battery stores throughout the charging process. A battery’s charge efficiency is determined by its chemistry, charging power, and the technique used in charging it.
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.
