Application Challenges
In the context of drones, mission feasibility assessment is crucial for determining what missions or use cases are possible. The TerraE 20P cell addresses several challenges faced by UAV operators, particularly in terms of energy management and performance reliability. For instance, drones often operate in extreme environments where temperature fluctuations can affect battery performance. The ability to accurately predict the state of charge (SoC) and manage thermal conditions is essential to prevent mid-air failures. The high energy density of the TerraE 20P cell allows for extended flight times, which is vital for long endurance drone batteries. Furthermore, the lightweight design of the cell contributes to improved UAV mission endurance, enabling drones to carry heavier payloads without compromising flight time. The simulation-based approach to mission planning helps operators make informed go/no-go decisions, ensuring that drones are ready for deployment under varying conditions.
Why this Cell
The TerraE 20P cell is particularly suited for mission feasibility assessments in drones due to its impressive specifications. With a maximum continuous discharge rate of 30 A, it is among the highest in the database, allowing for robust power delivery during demanding missions. The cell's volumetric energy density of 395 Wh/l, while around the median, still provides sufficient energy for various UAV applications. The gravimetric energy density of 160 Wh/kg ensures that the cell remains lightweight, which is critical for drone performance. Additionally, the top-quartile volumetric power density of 5,918 W/l supports high current demands, making it ideal for applications requiring rapid energy release. This combination of features enables UAV operators to optimise their battery pack design, ensuring that they can meet the specific energy and power requirements of their missions effectively.
How Model-Based Design Helps
Simulation and model-based design play a pivotal role in optimising the performance of the TerraE 20P cell for drone applications. By modelling load profiles, engineers can predict how the cell will behave under various operational conditions, including different temperatures and states of charge. This predictive capability allows for accurate assessments of battery performance, ensuring that drones can deliver the required thrust and energy throughout their flight envelope. For instance, simulations can help identify potential thermal issues, enabling designers to implement effective battery thermal management strategies. Furthermore, by analysing voltage sag and usable energy, operators can make informed decisions about mission feasibility, reducing the risk of mid-air failures. The ability to simulate different scenarios ensures that the TerraE 20P cell is not only selected based on theoretical performance but also validated under realistic conditions, enhancing operator confidence in drone readiness.
