Abstract

The research focuses on doing a thorough comparative analysis of different Battery Management Systems (BMS) used in modern battery technologies. Its goal is to completely examine and identify performance differences across several important parameters. Empirical data analysis reveals substantial disparities across batteries for crucial factors. The battery specs showed a range of capacities, with Battery B003 having the maximum capacity of 120 Ah and Battery B002 having the lowest capacity of 85 Ah. The temperature performance testing revealed significant variances in operating temperatures, with B003 exhibiting the widest temperature range of -20 to 50°C. Significant variations in the rates of charging and discharging were noted, with B004 exhibiting the greatest rates. Furthermore, there were significant differences in efficiency and aging properties. Specifically, B005 had the greatest efficiency, reaching 97%, and the lowest deterioration rate, which was just 0.09%. These data highlight significant variations across batteries, stressing the need for customized BMS techniques. The comparison study provides crucial insights into the complex intricacies of battery behavior, offering fundamental information essential for creating efficient BMS designs. Comprehending these differences is crucial for improving battery management techniques, guaranteeing effective and secure battery operations in various applications, and directing future progress in energy storage systems for electric cars, renewable energy, and portable devices.
