Application Challenges
In the context of EVTOL and the challenge to maximise flight time, optimising cell selection is crucial. Drones require batteries that can deliver consistent power while maintaining efficiency across varying duty cycles and flight speeds. The ability to extend flight time is directly linked to the energy density of the battery. With the LG Chem HG2 cell's high volumetric energy density, operators can achieve longer missions without compromising on payload capacity. Furthermore, the challenges of thermal management and battery safety are paramount, especially in extreme environments where overheating can lead to mission failure. Therefore, selecting the right cell is not just about capacity but also about ensuring reliability and safety during operations.
Why this Cell
The LG Chem HG2 cell is particularly suited for EVTOL applications due to its impressive specifications. With a maximum continuous discharge rate of 20 A, it supports high energy demands, making it ideal for UAVs that require rapid bursts of power. The cell's volumetric energy density of 616 Wh/l is top-quartile compared to the median of 541.67 Wh/l, allowing for longer flight times without increasing weight. This is critical for missions where every second counts. Additionally, the gravimetric power density of 1500 W/kg ensures that the cell can deliver the necessary power without adding excessive weight, thus optimising the overall performance of the UAV. The combination of these metrics makes the LG Chem HG2 a prime candidate for drone battery design, ensuring that operators can maximise flight time and efficiency.
How Model-Based Design Helps
Simulation and model-based design play a vital role in optimising battery selection for UAV applications. By simulating load profiles, thermal behaviour, and voltage response, engineers can accurately predict how the LG Chem HG2 cell will perform under various conditions. This approach allows for the identification of the optimal duty cycle and flight speed, ensuring that the cell operates within its safe limits while delivering maximum performance. For instance, modelling can reveal how the cell's energy output varies with temperature and state of charge (SoC), enabling operators to make informed decisions about mission feasibility. This predictive capability is essential for preventing mid-air failures and ensuring that drones can complete their missions reliably, especially in challenging environments.
