Comparative Analysis of Charging and Discharging Characteristics for Batteries in Aircraft Electric Power Systems

Abstract

Abstract—This paper presents a comparative analysis of the charging and discharging characteristics of batteries used in aircraft electric power systems. The performance and efficiency of different battery technologies play a crucial role in determining the viability of electric propulsion and power systems in aircraft applications. In this study, we systematically evaluate the charg- ing and discharging behaviors of various battery types, including LiFePO4, Ni-Cd, and lead acid, using Simulink. The simulations encompass state of charge (SOC) dynamics, charging efficiency, discharging profiles, and passive cell balancing technique. By utilizing Simulink, we can accurately model the behavior of different battery technologies under various operating conditions. The results obtained from the simulations provide valuable insights into the performance, efficiency, and overall suitability of battery technologies for aircraft electric power systems. This comparative analysis, serves as a valuable resource for engineers and researchers involved in the design and optimization of battery management systems for aircraft applications, aiding in the informed selection and integration of batteries in aircraft electric power systems.
