Application Challenges
In the realm of drones, maximising flight time is paramount. This involves optimising the cell selection, duty cycle, and flight speed to ensure that UAVs can operate effectively over extended periods. The challenge lies in balancing energy consumption with the need for power during critical phases of flight, such as takeoff and manoeuvring. The TerraE 20P cell addresses these challenges with its high energy density and robust discharge capabilities, allowing for longer missions without the need for frequent recharges. The ability to extend drone flight time is crucial for applications such as industrial inspections, where every minute of airtime counts. Additionally, ensuring that the battery does not overheat during high discharge scenarios is vital for maintaining operational safety and efficiency.
Why this Cell
The TerraE 20P cell is specifically engineered for drone applications where maximising flight time is essential. With a nominal capacity of 7.2 Wh and a maximum continuous discharge rate of 30 A, this cell is designed to meet the demanding requirements of UAVs. Its volumetric energy density of 395 Wh/l is significantly higher than the median of 542 Wh/l, allowing for a more compact battery design that does not compromise on performance. The high gravimetric power density of 2,400 W/kg ensures that the cell can handle rapid energy demands, making it suitable for high energy density drone batteries. This combination of features makes the TerraE 20P an excellent choice for custom UAV battery packs, ensuring that operators can achieve their mission objectives without the risk of battery failure.
How Model-Based Design Helps
Simulation and model-based design play a critical role in optimising battery performance for drone applications. By modelling load profiles, thermal behaviour, and voltage response, engineers can accurately predict how the TerraE 20P cell will perform under various conditions. For instance, simulating the thermal rise during high discharge scenarios helps in selecting the right cell to prevent overheating, which is a common pain point in drone battery design. Additionally, using cell-specific data allows for precise predictions of usable energy across different flight profiles, ensuring that operators can make informed decisions about mission feasibility. This approach not only enhances battery thermal management for drones but also improves UAV mission endurance by allowing for accurate predictions of battery state of charge (SoC) and performance under varying environmental conditions.
