The Amprius SA88 cell is particularly suited for drones due to its impressive specifications. With a volumetric energy density of 777 Wh/l, it allows for lightweight drone battery packs that do not compromise on performance. The maximum continuous charge of 100 A ensures that the cell can handle high discharge rates, which is essential for UAV battery optimisation. This cell's gravimetric energy density of 356 Wh/kg is significantly above the median, making it an ideal choice for applications requiring high energy density. The combination of these metrics supports the mission feasibility assessment by providing reliable power for various drone operations.
How Model-Based Design Helps
Simulation and model-based design play a critical role in optimising drone battery performance. By modelling load profiles, thermal behaviour, and voltage response, engineers can predict how the Amprius SA88 cell will perform under different mission scenarios. This allows for accurate assessments of usable energy and helps in selecting the right cell for specific applications. For instance, simulating the thermal rise during high discharge rates can prevent overheating and ensure safe operation. Additionally, these simulations enable engineers to make informed go/no-go decisions based on real-time data, enhancing the reliability of drone missions.
