How Model-Based Design Helps
Simulation and model-based design play a crucial role in optimising the performance of the MaxAmps MA-8000 in EVTOL applications. By modelling load profiles, thermal rise, and voltage sag, engineers can predict how the cell will behave under various operational conditions. This predictive capability allows for the selection of the most suitable cells for specific missions, ensuring that the battery can deliver the required thrust and energy throughout the flight envelope. For instance, simulations can identify the optimal charging protocols that prevent overheating while maximising efficiency. This approach not only enhances the reliability of the UAV but also reduces the risk of mid-air failures, making it a vital tool in the design and testing of drone battery packs.
