Abstract
With the acceleration of aviation electrification,electric vertical take-off and landing vehicles(eVTOL)have shown broad prospects in fields such as emergency rescue,medical transfer,logistics and distribution,and urban commuting.The cur-rent energy density and charging efficiency of lithium-ion batteries limit their commercial application.This paper systematically analyzes the characteristics and application potential of three power technologies:solid state batteries,renewable fuel cells,and hydrogen fuel cells.Solid state batteries have high energy density and excellent cycle life;hydrogen fuel cells provide new solu-tions for battery life with high energy conversion efficiency and rapid filling.The research result shows that diversified power supply is the development trend of eVTOL,and hybrid power systems are expected to achieve an optimal balance between per-formance and cost in different application scenarios.关键词
