How Model-Based Design Helps
Simulation and model-based design play a crucial role in optimising battery selection for UAV applications. By modelling load profiles, thermal behaviour, and voltage response, engineers can predict how the TerraE 20P cell will perform under various conditions. This includes assessing its thermal rise during high discharge scenarios and understanding its usable energy across different flight profiles. For instance, simulations can identify the optimal duty cycle and flight speed that maximise flight time while preventing overheating. This predictive capability allows for informed decision-making when selecting battery cells, ensuring that the chosen cell meets the specific requirements of the mission profile. By utilising simulation, manufacturers can avoid costly trial-and-error testing and enhance the reliability of their UAV systems.
