Why is energy storage important in eVTOL aircraft operation?
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].
How to determine the size of aircraft energy storage systems?
Based on the comprehensive analysis of hydrogen economy, FC aging cost, and aircraft stability, a multi-objective parameter optimization model is established to decide the size of aircraft energy storage systems and hyper-parameters in the power controller.
Can fuel cell and battery energy storage improve aircraft performance?
Recent developments in fuel cell (FC) and battery energy storage technologies bring a promising perspective for improving the economy and endurance of electric aircraft. However, aircraft power system configuration and power distribution strategies should be reasonably designed to enable this benefit.
How can hybrid energy storage technology improve the longevity of aircraft?
Compared to FC aircraft, the use of hybrid energy storage technology can significantly relieve the working pressure of FC stack. As shown in (b), even a small battery can reduce 17% and 9% FC poor working hours, which indicates that the FC longevity is successfully protected.
