Charging Time of Battery = Battery Ah ÷ Charging Current T = Ah ÷ A and Required Charging Current for battery = Battery Ah x 10% A = Ah x 10% Where, T = Time in hrs. Example: Calculate the suitable charging current in Amps and the needed charging time in hrs for a 12V, 120Ah battery. Solution: Battery Charging Current:
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.
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.
An equation is given for calculation of Charge/Discharge efficiency rate during charging mode which is: Eta= 1-exp (20,73* (SOC-1) / (I/I10)+0,55) Where I10 is the current at C10 I is the battery current
All battery parameters are affected by battery charging and recharging cycle. A key parameter of a battery in use in a PV system is the battery state of charge (BSOC). 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.
Discharge Efficiency: This parameter measures the proportion of energy provided by the battery when discharging. Battery type, load, and ambient temperature all have an influence on discharge efficiency. A higher discharge efficiency leads to longer battery life, making your battery serve you well with improved performance.
For batteries, under Galvanostatic conditions (constant current), the energy released in discharging or the energy consumed in charging is the integration of the respective portions of the GCD plot.
