Application Challenges
In the context of drones, maximising flight time is crucial. The Samsung 40T3 cell addresses this challenge by optimising cell selection, duty cycle, and flight speed. High energy density is essential for extending drone flight time, particularly in demanding environments. The ability to maintain performance under varying loads is vital, as drones often operate in conditions that require reliable energy output. The challenge lies in ensuring that the battery can deliver consistent power without overheating or compromising safety. Simulation and model-based design play a key role in predicting performance and optimising battery use, ensuring that drones can achieve their mission objectives effectively.
Why this Cell
The Samsung 40T3 cell is an excellent choice for drone applications due to its impressive specifications. With a maximum continuous discharge of 50 A, it is in the top-quartile compared to the median of 30 A, making it suitable for high discharge rate UAV batteries. Its volumetric energy density of 579 Wh/l is also in the top-quartile, ensuring that drones can carry more energy without increasing weight. This is particularly important for long endurance drone batteries, where every gram counts. The cell's gravimetric power density of 2571 W/kg, which is around the median, provides a good balance between weight and power output, making it ideal for UAV battery optimisation.
How Model-Based Design Helps
Simulation and model-based design are critical in the selection of the Samsung 40T3 cell for drone applications. By modelling load profiles, thermal behaviour, and voltage response, engineers can predict how the cell will perform under various conditions. This approach allows for accurate assessments of energy usage and thermal management, which are essential for preventing overheating and ensuring safe operation. For instance, simulating different flight speeds can help identify the optimal cruise velocity that balances energy consumption and flight time. This predictive capability enables manufacturers to select the best cells for UAVs, ensuring that the drones can operate efficiently and reliably in the field.
