Predicting the Impact of Temperature on eVTOL Battery Systems Using Experimental Data from Airworthiness-Certified Fixed-Wing Electric Aircraft

<div class="section abstract"><div class="htmlview paragraph">This study leverages the temperature impact data obtained from the battery systems of airworthiness-certified fixed-wing electric aircraft to predict and correct the performance of eVTOL battery systems under various temperature conditions. Due to the lack of airworthiness-certified eVTOL models, it is challenging to directly test battery system parameters under temperature variations. However, using data from Ma Xin's team's production batteries tested on certified fixed-wing electric aircraft, we can accurately measure the effects of temperature changes. The capacity retention data at temperatures of -40°C, -20°C, -10°C, 0°C, 0°C, 25°C, 35°C, 45°C, 55°Care 78.14%, 83.3%, 84.1%, 88.1%, 92.3%, 100.0%, 102.0%, 103.9%, 104.6%. These quantified results provide a basis for modeling and experimental validation of eVTOL battery systems, ensuring their performance and safety across a wide range of temperatures. Although there are some research of battery system of eVtol in room temperature, the data and research of impact of various temperature on battery systems of eVTOLin this article is not published before.</div></div>
