With a maximum continuous discharge rate of 33.0 A, it is in the top-quartile compared to the median of 30 A, allowing for high discharge rates that are essential for UAV performance. Its volumetric energy density of 740 Wh/l is significantly higher than the median of 541.67 Wh/l, making it ideal for long endurance drone batteries. This high energy density translates to extended flight times, which is crucial for mission feasibility assessments. Additionally, the cell's gravimetric energy density of 340 Wh/kg ensures that UAVs can carry more payload without compromising on flight time. These metrics combined make the Amprius SA02 a strong candidate for custom UAV battery packs, optimising both performance and efficiency.
How Model-Based Design Helps
Simulation and model-based design play a pivotal role in the selection and optimisation of the Amprius SA02 cell for UAV applications. By modelling load profiles, thermal rise, and voltage sag, engineers can predict the cell's performance under various operational scenarios. This allows for accurate assessments of usable energy and helps in understanding the thermal behaviour of the cell during high-demand missions. For instance, simulating different flight profiles can reveal how the battery performs under varying conditions, enabling engineers to make informed decisions about battery selection. This approach not only enhances the reliability of the UAV but also supports the go/no-go decision-making process by providing data-driven insights into battery performance. Ultimately, this leads to improved UAV mission endurance and efficiency, ensuring that operators can confidently deploy their drones in critical situations.
