How Model-Based Design Helps
Simulation and model-based design play a crucial role in optimising the performance of the Amprius SA11 cell for drone applications. By modelling load profiles and thermal behaviour, engineers can predict how the cell will perform under different conditions, including varying flight speeds and payloads. This approach allows for accurate assessments of voltage sag, heat generation, and usable energy throughout the flight envelope. For instance, simulations can help determine the optimal duty cycle that maximises flight time while preventing overheating. By using cell-specific data, designers can confidently select the SA11 cell for specific missions, ensuring that drones can operate reliably in demanding environments. This predictive capability reduces the risk of mid-air failures and enhances overall mission success rates.
