How Model-Based Design Helps
Simulation and model-based design play a vital role in optimising the selection of the TerraE 25P4 cell for various drone applications. By modelling load profiles, thermal behaviour, and voltage response, engineers can accurately predict how the cell will perform under different conditions. For instance, simulating the thermal rise during high discharge scenarios helps in selecting cells that maintain optimal performance without overheating. This is particularly important for heavy-lift drone applications, where continuous current draw can lead to thermal runaway if not properly managed. Furthermore, simulation allows for the evaluation of usable energy across the entire flight envelope, enabling operators to make informed decisions about mission feasibility based on temperature and state-of-charge (SOC). By leveraging these advanced modelling techniques, manufacturers can confidently select the best cells for UAV packs, ensuring reliability and efficiency in their designs.
