Simultaneously, the safety of the energy storage system is an indispensable aspect of eVTOL aircraft operation. Battery charging, discharging, and temperature management must be strictly controlled to prevent overcurrent, overheating, and other safety issues [7, 8].
Therefore, when designing battery management systems for electric aircraft, it's important to consider controlling the charging speed to balance the relationship between charging speed and battery cycle life, ensuring the battery's sustainable use and performance stability. Fig. 6.
The electrical system of the aircraft includes a propulsion system and an aircraft power supply (APS) system. The load is supplied by the generator, to achieve the purpose of a comprehensive utilization of energy and unified management.
In solar hybrid systems, batteries or fuel cells are usually used as auxiliary energy storage systems (Mane et al., 2016). Lithium polymer (Li-Po), lithium ion (Li-ion), and lithium-sulfur (Li-S) batteries and fuel cells are the most preferred energy storage systems in solar-powered air vehicles (Elouarouar & Medromi, 2022).
Therefore, future efforts need to focus on in-depth research in various fields such as material science, battery management systems, thermal management technologies, and safety protection measures, to promote the comprehensive improvement of the safety and performance indicators of eVTOL aircraft energy storage systems.
