Its maximum continuous discharge of 400 A positions it in the top-quartile compared to the median of 30 A in the database, ensuring that it can handle the high discharge rates required for dynamic flight profiles. The volumetric energy density of 351 Wh/l, while around the median, still provides a robust solution for UAV battery optimisation. This cell's lightweight design and high energy output make it a prime candidate for custom UAV battery packs, allowing for tailored solutions that enhance drone performance. By selecting the 82D6J7, engineers can effectively address the challenges of drone battery design, ensuring that their UAVs can perform optimally across various mission profiles.
How Model-Based Design Helps
Simulation and model-based design play a crucial role in optimising the performance of the COSMX 82D6J7 cell for drone applications. By modelling load profiles, engineers can predict how the cell will behave under different operational scenarios, including varying flight speeds and payloads. This predictive capability allows for accurate assessments of thermal rise and voltage sag, which are critical for ensuring safe operation and preventing overheating. Furthermore, simulation enables the evaluation of usable energy across the entire flight envelope, ensuring that the selected cell meets the energy demands of the mission. For instance, by simulating different duty cycles, engineers can identify the optimal balance between energy consumption and flight time, ultimately leading to improved drone powertrain efficiency. This approach not only enhances the reliability of UAV operations but also reduces the need for costly trial-and-error testing, making it an essential tool in the design of high-performance drone battery packs.
