This study explores how thermal management system design impacts battery performance and life in a 19-seat passenger regional electric aircraft. Using physics-based modeling, three key subsystems are sized: the heat acquisition network within each battery module, a fuselage-integrated heat exchanger that rejects heat to the atmosphere, and all associated auxiliary components. The power consumption of each thermal management system component throughout all flight phases is quantified and, by establishing the aircraft's maximum achievable range. Realistic projections for metropolitan air mobility are provided. Alternative thermal management system sizing strategies are expanded to highlight the repercussions of oversizing a thermal management system while maintaining cell temperatures within safe limits and mitigating performance fade. This analysis accounts for system-level interactions: thermal management system mass itself increases propulsion power demand, which in turn draws more current from the battery. By performing Latin Hypercube sampling across multiple configurations, variations in thermal and electrical profiles driving battery degradation are mapped.
