Application Challenges
In EVTOL applications, maximising flight time is paramount. The Tenpower 15SG cell addresses this challenge by optimising cell selection, duty cycles, and flight speeds. The ability to deliver high energy density is crucial for extending flight durations, especially in demanding environments. The challenge lies in balancing energy output with weight constraints, ensuring that the UAV can operate efficiently without overheating or compromising safety. The high discharge rates required for take-off and manoeuvring further complicate the design, necessitating careful consideration of thermal management and battery performance under varying conditions.
Why this Cell
The Tenpower 15SG cell is specifically designed to meet the demands of EVTOL applications. With a maximum continuous charge rate of 6 A, it allows for rapid recharging, which is essential for operational efficiency. The cell's volumetric energy density of 313 Wh/l ensures that UAVs can carry more energy without increasing weight, which is critical for maximising flight time. Additionally, the cell's gravimetric power density of 2643 W/kg is top-quartile compared to the median, allowing for high performance during critical flight phases. This combination of features makes the 15SG an excellent choice for UAV battery optimisation.
How Model-Based Design Helps
Simulation and model-based design play a crucial role in optimising the performance of the Tenpower 15SG cell in EVTOL applications. By modelling load profiles and thermal behaviour, engineers can predict how the cell will perform under various conditions. This includes assessing voltage sag during high discharge scenarios and estimating usable energy across different duty cycles. Such simulations enable the selection of the most suitable cell for specific missions, ensuring that UAVs can achieve their maximum flight time while maintaining safety and reliability. By avoiding costly trial-and-error testing, simulation enhances confidence in the cell's performance and operational readiness.
