The cell's gravimetric energy density of 161 Wh/kg is advantageous for lightweight drone battery packs, allowing for extended flight times without adding unnecessary weight. Compared to the database median, this cell's energy density is around the median, providing a balanced solution for UAV battery pack design. The high volumetric power density of 5,687 W/l supports rapid energy delivery, making it ideal for applications requiring quick bursts of power, such as take-offs and rapid climbs.
How Model-Based Design Helps
Simulation and model-based design play a crucial role in optimising the performance of the Tenpower 30TG cell for EVTOL applications. By modelling load profiles, engineers can predict how the cell will behave under various conditions, including thermal rise and voltage sag. This allows for accurate predictions of usable energy and helps in selecting the best cell for specific mission profiles. For instance, simulating different flight speeds can identify the optimal cruise velocity that balances energy consumption and aerodynamic efficiency. This approach not only enhances battery thermal management for drones but also ensures that the selected cell can deliver the required performance across the entire flight envelope, thereby improving UAV mission endurance and reliability.
