This cell's gravimetric power density of 1543 W/kg ensures that it meets the needs of UAVs focused on performance and endurance, making it a strong contender in the competitive market of drone battery design.
How Model-Based Design Helps
Simulation and model-based design play a critical role in optimising battery performance for drones. By simulating load profiles, thermal behaviour, and voltage responses, engineers can accurately predict how the Tenpower 50SG cell will perform under various conditions. This approach allows for the identification of the best cell for specific mission profiles, ensuring that the selected battery can handle the required energy output without overheating or failing. For instance, modelling can reveal how the cell behaves during high discharge scenarios, which is vital for maintaining drone efficiency and safety. This predictive capability reduces the risk of costly trial-and-error testing and enhances overall mission reliability.
