With a maximum continuous discharge of 30 A, it is positioned in the top-quartile compared to the database median of 30 A, ensuring that it can handle high power demands during flight. The volumetric energy density of 543 Wh/l is also noteworthy, as it allows drones to maximise their energy storage without compromising on weight. This is particularly important for UAV battery pack design, where every gram counts. Furthermore, the gravimetric power density of 2,438 W/kg is among the highest in the database, enabling quick bursts of power when required. These characteristics make the VTC5 an excellent choice for custom UAV battery packs aimed at enhancing mission feasibility.
How Model-Based Design Helps
Simulation and model-based design play a pivotal role in optimising the performance of the Murata VTC5 cell for drone applications. By modelling load profiles, engineers can predict how the cell will behave under various conditions, including different temperatures and states of charge. This predictive capability allows for accurate assessments of whether a drone can complete its mission without failure. For instance, simulating thermal behaviour helps identify potential overheating issues, ensuring that the selected cell can operate safely within its limits. Additionally, voltage sag and usable energy can be accurately forecasted, enabling engineers to make informed decisions about battery selection and configuration. This approach reduces the risk of costly trial-and-error testing and enhances the reliability of go/no-go decisions for mission planning.
