Abstract: In this paper, the state of charge of the battery is determined and the battery is allowed to charge or discharge by standard reference current, since the overcharging and undercharging would affect the battery performance. So a battery should not be fully charged or discharged, because overcharging of a battery will affect the life time of the battery and undercharging of a battery will increase the initial charging time. Online estimation to determine SOC of battery is attempted in the proposed work with the electrical parameters which is developed using an intelligent controller.
Keywords: Online estimation to determine SOC of battery.
