Real-world study: how hot weather impacts electric aircraft battery performance
The Pipistrel Velis Electro is a common sight at summer airshows as it brings 100% electric flight before the public. Meanwhile the business models incorporating battery-powered aircraft ask how they will compete with conventional counterparts in a variety of weather conditions, especially as the earliest commercial eVTOLs are set to fly in places like Abu Dhabi where temperatures regularly top 40°C.
A recent study from The University of Waterloo shows encouraging signs.
Analysing flight data from Sealand Flight’s Velis Electro during a period of unusually hot weather, the energy consumption (%SOC/min) between 13°C and 33.4°C was found to have no statistical difference within the data set, even during different phases of flight. Researchers concluded:
Overall, the e-plane was designed to handle hot days with battery temperatures remaining well within the normal range. The discharge rates or energy used for various flight activities at high temperatures remained similar to those at lower temperatures.
Lithium battery performance is a core focus for regulators and insurers when considering new eVTOL aircraft, so the fact that some launch markets are located in hot climates draws more attention to cooling systems. This gives OEMs an early opportunity to demonstrate safe operations in harsh conditions, building confidence for both industry stakeholders and the public.
