Battery management system design for the generator systems intended to hybrid unmanned aereal vehicl

 The tendency towards electric propulsion/motor systems is increasing due to reasons such as the unsustainability of fossil fuel sources and the environmental damage of internal combustion engine vehicles working with fossil fuels. Electric propulsion systems; It is a promising option to achieve goals such as more reliable, environmentally friendly, sustainable and flexible design possibilities. While developing propulsion systems for electric vehicles, battery technologies also need to be developed. For this reason, batteries have a strategic importance in aviation to improve the electric propulsion system. In battery technology, lithium-ion batteries provide higher energy density and specific energy compared to other electrical energy storage systems. It is important to monitor and manage the cells in the battery pack in order to eliminate the imbalances between the cells and to operate the cells efficiently. In addition, rapid developments in power electronics have allowed the development of battery management systems (BMS) and the more efficient use of battery technology in unmanned aerial vehicles (UAV). In aviation applications, the BMS application is critical. In this study, an 8-cell battery pack was designed to provide energy to the electric propulsion system in UAVs. In addition, in order to manage the battery pack, the Battery Management System (BYS) was designed in MATLAB Simulink program, based on the inductor-based active cell balancing method.
