Electric Vertical Takeoff and Landing (eVTOL) flying cars constitute a prospective technological trajectory for the evolution of urban air mobility. However
a great challenge to the thermal management system is raised by the high heat dissipation power demand of its power battery and the variability of application scenarios. To address this challenge
a thermal management framework is designed in this paper that can simultaneously meet the thermal management objectives of the battery and the passenger cabin
and can switch between land and flight modes. Based on the 1D simulation software Amesim
a thermal management simulation platform for eVTOL was built to investigate the different requirements of thermal management for three flight missions and quick charging. Results of the simulation show that: The eVTOL thermal management targets for standard missions were achieved under this thermal management framework; multi-stage constant-current fast charging enables the eVTOL to quickly proceed to the next mission with a lower battery temperature compared to instant fast charging; lower payload
larger climb rate and flight temperatures of 10 - 26℃ help reduce thermal management difficulties and improve flight range. The thermal management solution proposed by this paper supports the application of eVTOL in urban air mobility.
