Application Challenges
In the aerospace sector, maximising flight time is crucial for UAVs, particularly in applications such as industrial inspections and emergency response. The Molicel P50B cell addresses the challenge of optimising cell selection, duty cycle, and flight speed to enhance endurance. The ability to deliver high energy density is vital, as it directly impacts the operational range and efficiency of drones. In scenarios where every minute of airtime counts, such as remote asset inspections, the right battery choice can significantly extend mission capabilities while maintaining safety and performance.
Why this Cell
The Molicel P50B cell is engineered for aerospace applications, offering a maximum continuous discharge of 60 A, which is in the top-quartile compared to the database median of 30 A. This high discharge capability is essential for UAVs that require rapid bursts of power during critical phases of flight. Additionally, its volumetric energy density of 703 Wh/l ensures that drones can carry more energy without increasing weight, a key factor in maximising flight time. The combination of high energy and power densities makes the P50B an ideal choice for long endurance drone batteries, enabling operators to achieve their mission objectives efficiently.
How Model-Based Design Helps
Simulation and model-based design play a crucial role in optimising UAV battery performance. By simulating load profiles, thermal behaviour, and voltage responses, engineers can predict how the Molicel P50B cell will perform under various conditions. This approach allows for accurate modelling of energy consumption and thermal management, ensuring that the selected cell meets the specific demands of the mission. For instance, simulating different flight speeds can help identify the optimal cruise velocity that balances energy use and performance. This predictive capability not only enhances the reliability of drone operations but also reduces the risk of mid-air failures, making it a vital tool in UAV battery design.
