Application Challenges
In EVTOL applications, safety and risk management are paramount, particularly concerning overheating and thermal runaway during flight. The Tenpower 30TG cell's high energy density and robust discharge capabilities are crucial for maintaining performance under demanding conditions. Overheating can lead to catastrophic failures, making it essential to select cells that can operate safely within their thermal limits. The ability to discharge at a maximum of 40 A allows for extended flight times while managing the heat generated during operation. This is particularly relevant for UAVs operating in extreme environments where thermal management is critical. The cell's design must also consider the weight-to-power ratio, as every gram counts in UAV design, impacting overall mission endurance and efficiency.
Why this Cell
The Tenpower 30TG cell is specifically designed for EVTOL applications, addressing the critical challenge of safety and risk management. With a maximum continuous discharge of 40 A, it is positioned in the top-quartile compared to the median of 30 A, ensuring that it can meet the high power demands of UAVs during flight. Its volumetric energy density of 426 Wh/l, while around the median of 541 Wh/l, still provides a competitive edge in terms of space efficiency. This cell's lightweight design, with a gravimetric energy density of 161 Wh/kg, is essential for maintaining optimal flight performance. The combination of these metrics makes the 30TG an ideal choice for applications requiring high energy density and safety, particularly in environments where overheating could pose significant risks.
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 and thermal behaviour, engineers can predict how the cell will perform under various conditions, including high discharge rates and extreme temperatures. This approach allows for accurate predictions of voltage sag and usable energy, ensuring that the selected cell meets the specific demands of the mission. For instance, simulating the thermal rise during continuous discharge helps identify potential overheating issues before they occur, enabling proactive design adjustments. This predictive capability is vital for ensuring reliability in mission-critical applications, where every detail can impact the success of a flight.
