With a maximum continuous charge rate of 9.0 A, it allows for rapid energy replenishment, crucial for maintaining operational readiness in time-sensitive missions. The cell's volumetric energy density of 628 Wh/l is top-quartile compared to the median, ensuring that drones can maximise their energy storage without increasing size or weight. Additionally, the high gravimetric power density of 4659 W/kg supports high discharge rates, making it suitable for applications requiring quick bursts of power, such as take-off and heavy lifting. This combination of features not only enhances drone performance but also ensures safety during fast charging, addressing the critical challenge of overheating and lithium plating.
How Model-Based Design Helps
Simulation and model-based design play a vital role in optimising the performance of the EVE Energy 30PL cell for drone applications. By modelling load profiles and thermal behaviour, engineers can predict how the cell will perform under various charging and discharging scenarios. This predictive capability allows for the identification of optimal charging rates that prevent overheating while maximising efficiency. For instance, simulations can demonstrate the thermal rise associated with different charge currents, enabling the selection of the safest and most effective charging strategy. Additionally, voltage sag and usable energy can be accurately forecasted, ensuring that drones can rely on the 30PL cell for consistent performance throughout their missions. This data-driven approach not only enhances the design of drone battery packs but also improves UAV battery performance testing, ultimately leading to safer and more reliable drone operations.
