With a volumetric energy density of 616 Wh/l, it is in the top-quartile compared to the median of 541 Wh/l, allowing for lightweight drone battery packs that do not compromise on power. Its gravimetric energy density of 225 Wh/kg is around the median, providing a balanced approach to weight and energy supply. The maximum continuous discharge rate of 20 A ensures that the cell can handle high discharge rates required for UAV operations, making it an excellent choice for custom UAV battery packs designed for endurance and efficiency. This combination of high energy density and robust discharge capabilities makes the HG2 cell a preferred option for drone battery design.
How Model-Based Design Helps
Simulation and model-based design play a crucial role in optimising the performance of the LG Chem HG2 cell in drone applications. By modelling load profiles and thermal behaviour, engineers can predict how the cell will perform under various conditions, such as different flight speeds and payloads. This allows for accurate predictions of usable energy and voltage response, which are essential for ensuring that drones can complete their missions without mid-air failures. For instance, simulations can help identify the optimal duty cycle that maximises flight time while preventing overheating. By using cell-specific data, designers can confidently select the HG2 cell, knowing it will deliver the required performance across the entire flight envelope. This approach reduces the risk of costly trial-and-error testing and enhances the reliability of drone operations.
