Furthermore, the lightweight design of the cell contributes to improved UAV mission endurance, allowing for more efficient flight profiles and payload capacities.
Why this Cell
The Samsung 50S cell is particularly well-suited for drone applications due to its impressive specifications. The nominal capacity of 18.0 Wh and 5.0 Ah allows for extended flight times, which is critical for missions requiring long endurance. Its volumetric energy density of 718 Wh/l is among the highest in the database, ensuring that drones can carry more energy without increasing weight. The maximum continuous discharge rate of 45 A positions it in the top-quartile, enabling high discharge rates necessary for demanding flight maneuvers. This performance is vital for applications that require rapid acceleration or heavy lifting, making the Samsung 50S an ideal choice for UAV battery pack design. Additionally, the cell's thermal management capabilities help prevent overheating, addressing one of the core challenges in drone battery cell selection.
How Model-Based Design Helps
Simulation and model-based design play a crucial role in optimising the performance of the Samsung 50S cell for drone applications. By modelling load profiles and thermal behaviour, engineers can predict how the cell will perform under various conditions, including high discharge rates and temperature fluctuations. This predictive capability allows for the selection of the most suitable cells for specific missions, ensuring that drones can operate reliably without the risk of thermal runaway. For instance, simulations can help determine the optimal charge and discharge rates, ensuring that the battery operates within safe limits while maximising energy output. Furthermore, by analysing voltage sag and usable energy, designers can refine their UAV battery performance testing, leading to improved powertrain efficiency and extended flight times. Overall, simulation enhances the design workflow, enabling the creation of custom UAV battery packs that meet the stringent demands of modern drone operations.
