About the Cell
The Molicel P28B is a cylindrical 18650 lithium-ion cell designed for drone applications. With a nominal capacity of 10.08 Wh and a nominal current of 2.8 Ah, it offers a robust solution for UAV battery pack design. The cell features a volumetric energy density of 569 Wh/l, which is significantly above the database median of 542 Wh/l, making it suitable for long endurance drone batteries. Additionally, its gravimetric energy density of 210 Wh/kg aligns with the industry standard, ensuring lightweight drone battery packs. The cell's volumetric power density of 8126 W/l is among the highest in the database, providing the necessary power for demanding applications. Furthermore, the maximum continuous discharge rate of 40 A allows for high discharge rate UAV batteries, essential for dynamic flight profiles.
Application Challenges
In the context of drones, mission feasibility assessment is critical. Operators must determine whether a drone can successfully complete its mission based on various factors, including battery performance under different conditions. The Molicel P28B cell's high energy density and discharge capabilities are vital for extending drone flight time and improving UAV mission endurance. Accurate predictions of battery state of charge (SoC) are crucial to prevent mid-air failures, especially in extreme environments. The lightweight design of the P28B also aids in enhancing drone powertrain efficiency, allowing for better payload management and operational flexibility.
Why this Cell
The Molicel P28B is particularly suited for mission feasibility assessments due to its impressive specifications. With a maximum continuous discharge of 40 A, it stands in the top-quartile compared to the database median of 30 A, ensuring reliable performance during high-demand scenarios. The cell's volumetric energy density of 569 Wh/l, which is significantly above the median, allows for longer missions without the need for additional weight. This makes it an ideal choice for UAV battery optimisation, as it balances energy needs with weight constraints, ultimately leading to improved drone endurance.
How Model-Based Design Helps
Simulation and model-based design play a pivotal role in optimising the performance of the Molicel P28B in drone applications. By modelling load profiles and thermal behaviour, engineers can predict how the cell will perform under various conditions. This includes assessing voltage sag and usable energy across the entire flight envelope. For instance, simulations can help determine the optimal cruise speed for a drone, ensuring that energy consumption is standardised across different pilots. This predictive capability is essential for making informed go/no-go decisions, particularly in mission-critical scenarios where reliability is paramount. By leveraging cell-specific data, operators can confidently select the Molicel P28B for their UAV applications, knowing it meets the necessary performance criteria.
