About the Cell
The Tenpower 20SG cell features a cylindrical 18650 form factor, providing a nominal capacity of 7.4 Wh and 2.0 Ah. With a volumetric energy density of 417 Wh/l, it ranks around the median compared to other cells in the database. Its gravimetric energy density of 172 Wh/kg is slightly below the median, yet it offers a top-quartile volumetric power density of 6257 W/l, which is +58% vs the database median of 2029 W/l. This combination of energy and power density makes it suitable for various UAV applications, particularly in maximising flight time. The cell's maximum continuous charge of 6 A and discharge of 30 A (15 C-rate) further enhance its performance in demanding scenarios.
Application Challenges
In the EVTOL sector, maximising flight time is crucial. The Tenpower 20SG cell addresses this by optimising cell selection, duty cycle, and flight speed. The ability to deliver high energy density is essential for long endurance missions, especially in harsh environments. UAVs often face challenges such as thermal management and energy efficiency, where the right battery selection can significantly impact mission success. The 20SG cell's specifications allow for extended flight durations, making it ideal for applications like industrial inspections and emergency response, where every minute of airtime is critical.
Why this Cell
The Tenpower 20SG cell is designed specifically for UAV applications, with a maximum continuous discharge of 30 A, placing it in the top-quartile compared to the median of 30 A in the database. Its volumetric energy density of 417 Wh/l is competitive, ensuring that UAVs can carry more energy without increasing weight. This is vital for missions that require long endurance and high performance. The cell's lightweight design, combined with its high discharge capabilities, makes it an excellent choice for optimising flight time and enhancing overall UAV efficiency.
How Model-Based Design Helps
Simulation and model-based design play a crucial role in selecting the right battery for UAV applications. By modelling load profiles, thermal behaviour, and voltage response, engineers can predict how the Tenpower 20SG cell will perform under various conditions. This approach allows for accurate predictions of usable energy and helps prevent issues such as overheating or insufficient power during critical flight phases. For instance, simulating different duty cycles can reveal the optimal charge and discharge rates, ensuring that the UAV operates efficiently throughout its mission. This predictive capability reduces the risk of mid-air failures and enhances mission reliability.
