Application Challenges
In the context of EVTOL and the weight versus power trade-off in pack design, selecting the right battery cell is crucial. UAVs require batteries that not only provide sufficient energy for extended flight times but also maintain a lightweight profile to enhance efficiency. The challenge lies in balancing these two factors to optimise performance. For instance, a higher energy density allows for longer missions, while a lower weight contributes to better manoeuvrability and reduced energy consumption. The Tenpower 20SG cell addresses these challenges effectively, making it an ideal candidate for applications requiring long endurance and high power output.
Why this Cell
The Tenpower 20SG cell is particularly well-suited for UAV applications due to its impressive specifications. With a volumetric energy density of 417 Wh/l, it ranks in the top-quartile compared to the database median, allowing for more energy storage in a compact form. Additionally, its maximum continuous discharge rate of 30 A ensures that it can meet the high power demands of UAVs during critical phases of flight. The gravimetric power density of 2581 W/kg is also among the highest in the database, providing the necessary power while keeping weight to a minimum. This balance of energy and power makes the 20SG an excellent choice for UAV battery pack design, ensuring optimal performance in various operational scenarios.
How Model-Based Design Helps
Simulation and model-based design play a vital role in optimising battery selection for UAV applications. By simulating load profiles, thermal behaviour, and voltage response, engineers can accurately predict how the Tenpower 20SG cell will perform under different conditions. For example, modelling the thermal rise during high discharge scenarios helps identify potential overheating issues, allowing for proactive design adjustments. Furthermore, simulations can assess the usable energy across various flight profiles, ensuring that the selected cell meets the specific energy requirements of the mission. This data-driven approach reduces the risk of trial-and-error testing, leading to more efficient and reliable UAV battery designs.
