What is the proposed battery efficiency calculation formula?
The proposed battery efficiency calculation formula uses the charging time, charging current, and battery capacity. An algorithm that can accurately determine the battery state is proposed by applying the proposed state of charge (SoC) and state of health (SoH) calculations.
How can we predict the SoH of a battery?
The SoH can be predicted from the CC charging time of the battery and the battery efficiency, as proposed in this paper. Furthermore, a safe system is implemented during charging and discharging by applying a fault diagnosis algorithm to reduce the battery efficiency.
How does the standard method predict the life time of a battery?
The standard method predicts the life time of a battery by analyzing it according to the chemical principle of the battery and through mathematical or physical modeling [ 74, 75, 76 ]; however, these methods do not consider the internal resistance of a battery, which significantly affects its life time.
How can a battery state be calculated accurately?
An algorithm that can accurately determine the battery state is proposed by applying the proposed state of charge (SoC) and state of health (SoH) calculations. To reduce the initial error of the Coulomb counting method (CCM), the SoC can be calculated accurately by applying the battery efficiency to the open circuit voltage (OCV).
Can a battery efficiency algorithm be used to predict the SOC and Soh?
The results suggest that the battery efficiency of the proposed algorithm could be applied for predicting the SoC and SoH, which requires improved accuracy, while the change in the internal resistance (which has the greatest impact on the battery state) could also be applied to increase the accuracy of the battery state prediction.
How does aging affect battery efficiency?
Aging increases the internal resistance of a battery and reduces its capacity; therefore, energy storage systems (ESSs) require a battery management system (BMS) algorithm that can manage the state of the battery. This paper proposes a battery efficiency calculation formula to manage the battery state.
