With a nominal capacity of 18.0 Wh and a maximum continuous discharge rate of 80 A, it supports high energy demands during flight. The volumetric energy density of 724 Wh/l is in the top-quartile compared to the median of 542 Wh/l, making it an excellent choice for long endurance drone batteries. Furthermore, the gravimetric power density of 4,000 W/kg is among the highest in the database, ensuring that the cell can deliver power efficiently during critical phases of flight. This combination of high performance metrics allows for effective UAV battery optimisation and reliable mission feasibility assessments.
How Model-Based Design Helps
Simulation and model-based design play a vital role in optimising the selection of battery cells for drone applications. By modelling load profiles, thermal behaviour, and voltage response, engineers can predict how the EVE Energy 50PL cell will perform under various conditions. This allows for accurate assessments of usable energy and helps in identifying potential overheating issues before they occur. For instance, simulations can reveal how the cell behaves during high discharge scenarios, ensuring that the selected battery can handle the demands of specific missions. This predictive capability supports informed decision-making, reducing the risk of mid-air failures and enhancing overall mission reliability.
