Application Challenges
In aerospace, mission feasibility assessment is critical for determining which missions or use cases are viable. The TerraE 32P cell's specifications directly impact the ability to assess these missions accurately. For example, the high energy density allows for longer flight times, which is essential for UAV operations. The ability to discharge at 30 A ensures that the drone can handle peak power demands without risking battery failure. Furthermore, the lightweight design contributes to improved UAV performance, enabling better payload management and extended operational range. Accurate predictions of battery state of charge (SOC) are vital to prevent mid-air failures, especially in extreme environments where temperature fluctuations can affect battery performance.
Why this Cell
The TerraE 32P cell is an ideal choice for mission feasibility assessments due to its high energy density and robust discharge capabilities. With a maximum continuous discharge of 30 A, it ranks among the highest in the database, ensuring that UAVs can perform demanding tasks without overheating or failing. The volumetric energy density of 630 Wh/l allows for compact designs, making it suitable for various UAV configurations. This cell's specifications enable engineers to choose cells for UAVs confidently, knowing they can optimise battery thermal management and improve overall mission endurance. The combination of high performance and reliability makes the TerraE 32P a preferred option for custom UAV battery packs.
How Model-Based Design Helps
Simulation and model-based design play a crucial role in selecting the right battery cells for UAV applications. By modelling load profiles, engineers can predict how the TerraE 32P cell will perform under different conditions, including thermal rise and voltage sag. This predictive capability allows for accurate assessments of usable energy and helps in making informed go/no-go decisions for mission planning. For instance, simulating various flight scenarios can reveal how the cell behaves at low states of charge (SoC) or in extreme temperatures, ensuring that the UAV can reliably complete its mission. This approach not only enhances operational efficiency but also reduces the risk of costly failures during critical missions.
