About the Cell
The LG Chem HG2 cell features a cylindrical 18650 form factor, providing a nominal capacity of 10.8 Wh and 3.0 Ah. With a volumetric energy density of 616 Wh/l, it ranks in the top-quartile compared to the database median of 541.67 Wh/l, making it suitable for long endurance drone batteries. The gravimetric energy density of 225 Wh/kg is also notable, being around the median of 210 Wh/kg. Additionally, the cell boasts a volumetric power density of 4107 W/l, which is among the highest in the database, exceeding the median of 2029.31 W/l. The maximum continuous discharge rate of 20 A, equivalent to a C-rate of 6.7, positions it well for high-demand applications, significantly above the median of 30 A. These specifications make the HG2 cell an excellent choice for UAV battery pack design, particularly in mission-critical scenarios.
Application Challenges
In EVTOL applications, mission feasibility assessment is crucial for determining which missions or use cases are viable. The ability to accurately predict energy availability and performance under various conditions is essential. For instance, high energy density is vital for extending drone flight times, while reliable discharge rates are necessary to ensure that drones can perform their tasks without mid-air failures. The LG Chem HG2 cell's specifications, including its high volumetric energy density and robust discharge capabilities, directly address these challenges, providing the necessary performance for UAVs operating in demanding environments.
Why this Cell
The LG Chem HG2 cell is particularly suited for mission feasibility assessments due to its impressive specifications. With a volumetric energy density of 616 Wh/l, it allows for compact battery designs that do not compromise on energy delivery. This is crucial for UAVs that require long endurance capabilities. Furthermore, its maximum continuous discharge rate of 20 A ensures that the cell can handle high power demands, making it ideal for applications requiring rapid energy release. Compared to the median discharge rate of 30 A in the database, the HG2's performance is commendable, supporting the need for reliable UAV battery 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 for EVTOL applications. By modelling load profiles, thermal behaviour, and voltage response, engineers can predict how the cell will perform under various mission scenarios. This includes assessing the impact of temperature on battery performance and ensuring that the cell can deliver the required thrust throughout the flight envelope. The ability to simulate these conditions allows for informed go/no-go decision-making, reducing the risk of mid-air failures and enhancing operator confidence in mission readiness. Ultimately, this approach enables the selection of the most suitable cells for UAV applications, ensuring that the chosen battery packs meet the specific demands of each mission.
