Application Challenges
In the context of EVTOL applications, maximising flight time is critical. The JP40 cell's high energy density is essential for extending drone flight durations, especially in demanding environments. The challenge lies in optimising cell selection, duty cycle, and flight speed to achieve the best performance. Current or energy capacity directly impacts the ability to complete missions without mid-air failures, making it vital to choose cells that can deliver consistent power under varying conditions. The JP40's specifications help address these challenges effectively, ensuring reliable operation during critical missions.
Why this Cell
The Ampace JP40 cell is specifically designed to meet the demands of EVTOL applications. With a maximum continuous discharge of 60 A, it is in the top-quartile compared to the median of 30 A, ensuring that it can handle high current draws without overheating. Its volumetric energy density of 595 Wh/l is also among the highest in the database, allowing for longer flight times without increasing weight. This combination of high energy and power density makes the JP40 an ideal choice for UAVs, particularly when optimising for flight time and efficiency.
How Model-Based Design Helps
Simulation and model-based design play a crucial role in the selection of the Ampace JP40 cell for UAV applications. By modelling load profiles, thermal behaviour, and voltage response, engineers can predict how the cell will perform under various conditions. This allows for accurate assessments of usable energy and thermal management, ensuring that the selected cell can meet the demands of the mission profile. For instance, simulating different flight speeds can help identify the optimal cruise velocity that balances energy consumption and performance, ultimately leading to more efficient and reliable UAV operations.
