Application Challenges
In the EVTOL sector, safety and risk management are paramount, especially concerning overheating and thermal runaway during flight. The ability to manage these risks is critical, as UAVs often operate in varying environmental conditions that can affect battery performance. The nominal capacity of 9.0 Wh is essential for ensuring that drones can sustain longer missions while maintaining safety. High energy density is crucial to extend drone flight time, as it allows for more energy to be stored without significantly increasing weight. Furthermore, the maximum continuous discharge capability of 20 A is vital for ensuring that UAVs can handle sudden power demands without risking battery integrity. The 25PG cell's design addresses these challenges effectively, making it suitable for applications where reliability and performance are non-negotiable.

The Tenpower 25PG cell is specifically designed to meet the rigorous demands of UAV applications, particularly in safety and risk management. With a maximum continuous discharge of 20 A, it provides a robust solution for high discharge rate UAV batteries, ensuring that drones can perform under pressure. The volumetric energy density of 507 Wh/l is particularly advantageous for long endurance drone batteries, allowing for extended flight times without compromising on safety. Additionally, the gravimetric power density of 1600 W/kg positions it well within the top-quartile of the database, making it an excellent choice for applications that require lightweight drone battery packs. This cell's combination of high energy and power density ensures that it can effectively support the demanding operational profiles of modern UAVs, particularly in challenging environments.
How Model-Based Design Helps
Simulation and model-based design play a crucial role in optimising the performance of the Tenpower 25PG cell for UAV applications. By modelling load profiles and thermal behaviour, engineers can predict how the cell will perform under various conditions, including high discharge rates and temperature fluctuations. This predictive capability allows for the identification of potential overheating issues before they occur, ensuring that the cell can operate safely within its limits. Furthermore, simulations can help in understanding voltage sag and usable energy across the entire flight envelope, enabling designers to make informed decisions about battery pack configurations. This approach not only enhances the reliability of the UAVs but also reduces the need for costly trial-and-error testing, ultimately leading to more efficient and effective designs.
