With a maximum continuous discharge of 60 A, it is positioned in the top-quartile compared to the median of 30 A, making it ideal for high-demand applications. Its volumetric energy density of 628 Wh/l is among the highest available, allowing for compact battery designs that do not compromise on power. This is particularly important in EVTOL applications where weight is critical. The cell's gravimetric power density of 4659 W/kg supports efficient energy use, enabling longer flight times and improved mission endurance. By choosing the EVE Energy 30PL, UAV manufacturers can ensure they are selecting a cell that meets the rigorous demands of modern drone operations while optimising the weight versus power trade-off.
How Model-Based Design Helps
Simulation and model-based design play a crucial role in optimising battery selection for UAV applications. By simulating load profiles, thermal behaviour, and voltage response, engineers can predict how the EVE Energy 30PL cell will perform under various conditions. This approach allows for accurate modelling of heat generation and energy delivery, ensuring that the selected cell can meet the demands of specific missions. For instance, by assessing the maximum continuous discharge of 60 A, engineers can determine if the cell will maintain performance during peak loads. Additionally, simulations can help identify potential overheating issues, allowing for proactive thermal management strategies. This data-driven approach reduces the risk of trial-and-error testing, enabling manufacturers to confidently select the best cell for their UAV designs, ultimately enhancing operational efficiency and reliability.
