Application Challenges
In EVTOL applications, maximising flight time is critical. The Murata VTC6A cell addresses this challenge by optimising the selection of cells, duty cycles, and flight speeds. The ability to sustain high discharge rates while maintaining thermal stability is essential to prevent overheating and ensure safety during operation. With the increasing demand for long endurance drone batteries, the VTC6A's specifications allow for extended missions without compromising performance. The challenge lies in balancing energy consumption with the weight of the battery pack, as every gram counts in UAV design. The VTC6A's lightweight design and high energy density make it a suitable choice for these demanding applications.
Why this Cell
The Murata VTC6A cell is an excellent choice for EVTOL applications due to its impressive specifications. With a maximum continuous discharge of 40 A, it is in the top-quartile compared to the database median of 30 A, allowing for high power output when needed. Its volumetric energy density of 578 Wh/l is also noteworthy, being +7% vs the median, which means more energy can be packed into a smaller volume, crucial for UAV designs. The cell's gravimetric energy density of 199 Wh/kg is around the median, ensuring that it provides a good balance between weight and energy storage. These features make the VTC6A particularly well-suited for applications that require both high energy and power density, such as long endurance drone missions.
How Model-Based Design Helps
Simulation and model-based design play a vital role in optimising the performance of the Murata VTC6A cell for UAV applications. By modelling load profiles, engineers can predict how the cell will behave under various conditions, including different duty cycles and flight speeds. This allows for accurate predictions of thermal rise and voltage sag, which are critical for ensuring the cell operates within safe limits. Furthermore, simulations can help identify the optimal energy usage across different flight scenarios, enabling designers to maximise flight time while minimising the risk of battery overheating. By using cell-specific data, engineers can confidently select the VTC6A for specific missions, ensuring reliability and performance in the field.
