With a maximum continuous discharge of 50 A, it is in the top-quartile compared to the median of 30 A in the database, making it ideal for high discharge rate UAV batteries. The cell's volumetric energy density of 579 Wh/l is also noteworthy, as it exceeds the median, ensuring that UAVs can carry more energy in a compact form. This is critical for applications requiring long endurance, such as heavy lift drone batteries and fixed-wing UAV battery solutions. Furthermore, the cell's thermal management capabilities are enhanced by its design, which helps prevent overheating during high-demand scenarios, addressing pain points in UAV battery optimisation.
How Model-Based Design Helps
Simulation and model-based design play a vital role in optimising the performance of the Samsung 40T3 cell for UAV applications. By modelling load profiles, thermal rise, and voltage sag, engineers can predict the usable energy and performance of the cell under various conditions. This predictive capability allows for informed decision-making when selecting battery cells for specific missions. For instance, simulations can assess the impact of different flight speeds on energy consumption, helping to identify optimal cruise velocities that maximise efficiency. Additionally, modelling can simulate the effects of low temperatures and varying SoC on battery performance, ensuring that the UAV can reliably complete its mission without mid-air failures. This level of analysis is crucial for achieving mission success in demanding environments.
