Application Challenges
In the context of EVTOL and mission feasibility assessments, the Samsung 25S cell addresses critical challenges in drone battery design. The ability to accurately assess what missions or use cases are feasible using simulation is vital. Factors such as energy density, discharge rates, and thermal management directly impact the operational capabilities of drones. For instance, a high volumetric energy density allows for longer flight times, which is essential for missions requiring extended range or endurance. Furthermore, the maximum continuous discharge rate of 35 A ensures that the cell can handle demanding power requirements during critical flight phases, preventing mid-air failures and ensuring mission success.
Why this Cell
The Samsung 25S cell is particularly suited for EVTOL applications due to its impressive specifications. With a nominal capacity of 9.125 Wh, it provides reliable energy storage for various UAV missions. The top-quartile volumetric energy density of 526 Wh/l allows for efficient space utilisation within drone designs, making it ideal for long endurance drone batteries. Additionally, the maximum continuous discharge of 35 A ensures that the cell can meet high power demands, which is crucial for UAV battery optimisation. This performance is further supported by its gravimetric power density of 2680 W/kg, which is significantly above the median, allowing for lightweight drone battery packs that do not compromise on performance.
How Model-Based Design Helps
Simulation and model-based design play a crucial role in optimising the selection of the Samsung 25S cell for UAV applications. By modelling load profiles, thermal behaviour, and voltage response, engineers can predict how the cell will perform under various mission scenarios. For example, simulations can assess the impact of different discharge rates on battery temperature and usable energy, helping to prevent overheating and ensuring safe battery packs for UAVs. Furthermore, accurate modelling of energy consumption across different flight speeds allows for better mission planning, ultimately leading to improved UAV mission endurance. This predictive capability is essential for making informed go/no-go decisions during mission feasibility assessments, ensuring that operators can rely on their drones to perform as expected in critical situations.
