Application Challenges
In the realm of drones, maximising flight time is critical. This involves optimising cell selection, duty cycle, and flight speed to enhance overall performance. The TerraE 50P cell addresses these challenges effectively. With its high energy density, it allows for longer flight durations, which is essential for applications such as industrial inspections, surveying, and emergency response. The ability to maintain performance under varying loads and temperatures is crucial, especially in extreme environments where reliability is paramount. The challenge lies in ensuring that the battery can deliver consistent power without overheating or failing, which is where the advanced design of the TerraE 50P excels.
Why this Cell
The TerraE 50P cell is specifically engineered to meet the demands of drone applications. Its maximum continuous discharge rate of 50.0 A ensures that it can handle high power draws, making it suitable for tasks that require rapid acceleration or heavy lifting. The cell's volumetric energy density of 686 Wh/l is a significant advantage, allowing for lightweight drone battery packs that do not compromise on performance. Compared to the median values in the database, this cell offers a top-quartile performance that enhances UAV mission endurance. The combination of high energy and power densities makes the TerraE 50P an ideal choice for optimising flight time and efficiency in UAV operations.
How Model-Based Design Helps
Simulation and model-based design play a crucial role in the selection and optimisation of battery cells for drones. By simulating load profiles, thermal behaviour, and voltage response, engineers can predict how the TerraE 50P cell will perform under various conditions. This approach allows for accurate modelling of energy consumption and thermal rise, ensuring that the selected cell meets the specific requirements of the mission. For instance, by analysing the thermal behaviour during high discharge scenarios, potential overheating issues can be identified and mitigated. This predictive capability not only enhances the reliability of drone operations but also reduces the need for costly trial-and-error testing, leading to more efficient design processes.
