Electric vertical take-off and landing (eVTOL) aircraft have gained considerable interest for their potential to transform public services and meet environmental objectives. Designing an effective power supply for eVTOL is challenging due to the extreme power requirements during takeoff and landing. This work presents a power supply solution and energy management control for an all-electric hybrid energy storage system that integrates supercapacitors and batteries to enhance eVTOL endurance. The approach employs DC-DC converters to regulate power output from each source. The work is validated through simulations and preliminary experimental results
