Application Challenges
In the aerospace sector, maximising flight time is critical for UAV operations. The Samsung 50S cell is designed to optimise the selection of cells, duty cycles, and flight speeds, addressing the challenge of extending drone flight time. With a nominal capacity of 18.0 Wh, it provides the necessary energy for long endurance missions. The high discharge rates required for UAVs, particularly in demanding environments, necessitate cells that can deliver consistent performance without overheating. The Samsung 50S cell's maximum continuous discharge of 45 A ensures that it can meet these high demands, making it an ideal choice for applications where reliability and performance are paramount.
Why this Cell
The Samsung 50S cell is specifically engineered for aerospace applications, where maximising flight time is essential. Its high volumetric energy density of 719 Wh/l allows for lightweight drone battery packs, which is crucial for long endurance missions. The cell's gravimetric energy density of 250 Wh/kg ensures that it remains lightweight while providing substantial energy, making it a top choice for UAV battery optimisation. Furthermore, with a maximum continuous discharge rate of 45 A, it is well-suited for high energy density drone batteries that require quick bursts of power. This performance is particularly beneficial in scenarios where drone battery design must account for rapid energy demands, such as during take-off or heavy payload operations.
How Model-Based Design Helps
Simulation and model-based design play a vital role in optimising the selection of the Samsung 50S cell for UAV 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 identification of the most suitable cells for specific missions, ensuring that the selected battery can deliver the required thrust and energy throughout the flight. Additionally, simulations can help in understanding voltage sag and usable energy, which are critical for accurate drone battery state of charge (SoC) predictions. This level of analysis not only enhances the reliability of drone operations but also reduces the risk of mid-air failures, making it a crucial step in UAV battery pack design.
