Compared to the database median, the HG2's performance metrics place it in the top quartile, making it a reliable choice for UAV battery pack design and optimisation.
How Model-Based Design Helps
Simulation and model-based design play a pivotal role in optimising the performance of the LG Chem HG2 cell in drone applications. By modelling load profiles, engineers can predict how the cell will behave under various conditions, including thermal rise and voltage sag. This predictive capability allows for the selection of the most suitable cells for specific missions, ensuring that drones can operate effectively in diverse environments. For instance, simulations can help identify the optimal cruising speed for energy efficiency, thereby extending flight time and improving overall mission success rates. Additionally, accurate modelling of battery performance under different states of charge (SoC) and temperatures enables operators to make informed decisions about mission feasibility, reducing the risk of failures during critical operations.
