Application Challenges
In the context of drones, the mission feasibility assessment involves determining which missions or use cases are viable based on battery performance. The TerraE 50P cell's specifications are crucial for this assessment, as they directly influence the drone's operational capabilities. For instance, the high volumetric energy density of 686 Wh/l allows for longer flight times, which is essential for applications such as industrial inspections or emergency response missions. Additionally, the ability to sustain a maximum continuous discharge of 50 A ensures that the drone can handle sudden power demands without risking battery failure. This is particularly important in scenarios where accurate drone battery state of charge (SOC) prediction is critical to avoid mid-air failures. The lightweight design of the 50P cell also contributes to improved UAV mission endurance, allowing for heavier payloads or extended operational ranges, which are vital for effective mission planning.

With a volumetric energy density of 686 Wh/l, it ranks in the top-quartile compared to the median of 542 Wh/l in the database, making it an excellent choice for long endurance drone batteries. The gravimetric power density of 2400 W/kg is also noteworthy, placing it among the highest in the database, which is essential for applications requiring high discharge rates. This cell's maximum continuous discharge of 50 A ensures that it can deliver the necessary power for demanding UAV operations, while the maximum continuous charge rate of 15 A allows for efficient recharging. These attributes make the TerraE 50P an ideal candidate for custom UAV battery packs, ensuring that operators can confidently assess mission feasibility based on reliable performance metrics.
How Model-Based Design Helps
Simulation and model-based design play a critical role in optimising the performance of the TerraE 50P cell for drone applications. By modelling load profiles, thermal behaviour, and voltage response, engineers can accurately predict how the cell will perform under various conditions. For instance, simulating the thermal rise during high discharge scenarios helps in selecting the right cell for specific missions, ensuring that the battery does not overheat and compromise safety. Additionally, by analysing voltage sag and usable energy across different flight profiles, designers can determine the optimal operating conditions for the drone, enhancing overall powertrain efficiency. This approach allows for informed decision-making regarding battery selection, ensuring that the chosen cell meets the specific requirements of the mission while maximising flight time and reliability.
