About the Cell
The Tenpower 30PG cell features a cylindrical 18650 form factor, providing a nominal capacity of 10.8 Wh and 3.0 Ah. With a volumetric energy density of 611 Wh/l, it stands out in the market, being in the top-quartile compared to the database median of 542 Wh/l. Its gravimetric energy density of 230 Wh/kg is also competitive, being around the median of 209 Wh/kg. The cell's volumetric power density is an impressive 6105 W/l, which is among the highest in the database, exceeding the median of 2029 W/l by a significant margin. Additionally, the maximum continuous discharge rate of 30 A positions it well for high-demand applications, ensuring that it can deliver the necessary power without overheating or compromising performance. This combination of features makes the 30PG an excellent choice for UAV battery pack design, particularly where weight and power trade-offs are critical.
Application Challenges
In the context of EVTOL and the weight versus power trade-off in pack design, the Tenpower 30PG cell addresses several key challenges. UAVs require batteries that not only provide sufficient energy for extended flight times but also maintain a lightweight profile to enhance overall performance. The ability to optimise battery weight directly impacts flight time and operational efficiency. For example, in heavy-lift drone applications, the need for high energy density is paramount to ensure that the drone can carry its payload without sacrificing flight duration. Furthermore, thermal management becomes crucial, as high discharge rates can lead to overheating, which the 30PG cell is designed to mitigate through its robust thermal performance. By selecting the right cell, designers can ensure that their UAVs meet mission requirements while maximising efficiency and safety.
Why this Cell
The Tenpower 30PG cell is particularly suited for UAV applications due to its impressive specifications. With a nominal capacity of 10.8 Wh and a maximum continuous discharge of 30 A, it is designed to handle the rigorous demands of drone operations. Its volumetric energy density of 611 Wh/l places it in the top-quartile compared to the database median, allowing for more energy storage in a compact form. This is crucial for applications requiring long endurance, such as surveillance or delivery missions. The cell's gravimetric power density of 2298 W/kg also supports high performance during rapid acceleration and heavy lifting, making it an ideal choice for custom UAV battery packs. By leveraging the 30PG, engineers can achieve the right balance between weight and power, ensuring optimal flight performance.
How Model-Based Design Helps
Simulation and model-based design play a vital role in optimising the selection of the Tenpower 30PG cell for UAV applications. By simulating load profiles, engineers can predict how the cell will perform under various conditions, including thermal rise and voltage sag. This allows for accurate modelling of usable energy and helps in understanding the cell's behaviour during high discharge scenarios. For instance, by analysing the thermal behaviour of the 30PG under different mission profiles, designers can ensure that the cell will not overheat during extended operations. This predictive capability enables the selection of the most suitable cell for specific missions, reducing the risk of failure and enhancing overall reliability. Furthermore, simulation aids in evaluating battery weight versus flight time, ensuring that the chosen configuration meets the operational requirements without compromising safety or performance.
