How Model-Based Design Helps
Simulation and model-based design play a critical role in optimising drone battery performance. By simulating load profiles, thermal behaviour, and voltage response, engineers can predict how the LG Chem H51 cell will perform under different mission scenarios. This approach allows for accurate assessments of usable energy and helps identify potential issues such as overheating or insufficient thrust. For instance, modelling the thermal rise during high discharge scenarios can prevent battery damage and ensure safe operation. Additionally, simulation enables the evaluation of battery weight versus flight time, allowing for the selection of the optimal cell for specific missions. This data-driven approach reduces the risk of costly trial-and-error testing and enhances the reliability of drone operations.
