Battery Management System Algorithms: There are a number of fundamental functions that the Battery Management System needs to control and report with the help of algorithms. These include: Therefore there are a number of battery management system algorithms required to estimate, compare, publish and control.
Based on the battery efficiency formula, a formula that predicts the SoH of a battery based on the charging time required to safely operate the battery is also applied to the BMS algorithm to improve the reliability.
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.
Furthermore, a safe system is implemented during charging and discharging by applying a fault diagnosis algorithm to reduce the battery efficiency. The validity of the proposed BMS algorithm is demonstrated by applying it in a 3-kW ESS.
In this paper, the battery efficiency equation is used to predict the SoH of a battery considering the decrease in the CC charging time of the SoH due to the increase in the internal resistance of the battery and the fact that the capacity of a battery decreases when it heats up.
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.
