How Model-Based Design Helps
Simulation and model-based design play a critical role in optimising the performance of the EVE Energy 50PL cell for drone applications. By modelling load profiles and thermal behaviour, engineers can predict how the cell will perform under various conditions, including high discharge rates and temperature fluctuations. This predictive capability allows for the selection of the most suitable cells for specific missions, ensuring that the drones can operate safely and efficiently. For instance, simulations can help identify potential overheating issues before they occur, allowing for proactive measures to be taken. Additionally, by analysing voltage sag and usable energy across different flight scenarios, designers can make informed decisions that enhance drone powertrain efficiency and extend flight times. This approach not only improves the reliability of drone operations but also reduces the need for costly trial-and-error testing, ultimately leading to safer and more effective UAV deployments.
