The cell's volumetric energy density of 351 Wh/l is around the median, providing a good balance between size and energy storage. Additionally, the gravimetric power density of 3149 W/kg places it in the top-quartile, making it suitable for applications requiring quick bursts of energy. This combination of high energy and power density allows for extended flight times and improved UAV mission endurance, addressing the critical challenge of weight versus power in battery design.

How Model-Based Design Helps

Simulation and model-based design play a crucial role in optimising battery selection for UAVs. By simulating load profiles and thermal behaviour, engineers can predict how the COSMX 82D6J7 cell will perform under various conditions. This includes assessing voltage sag during high discharge scenarios and understanding the thermal rise during extended use. Such simulations enable the identification of the most suitable cells for specific missions, ensuring that the selected battery can deliver the required performance without overheating or failing. Furthermore, modelling usable energy helps in accurately predicting the state of charge (SoC), which is vital for mission planning and execution. This approach reduces the risk of mid-air failures and enhances operator confidence in drone readiness.
