How Model-Based Design Helps
Simulation and model-based design play a crucial role in optimising battery performance for drone applications. By simulating load profiles, thermal rise, and voltage sag, engineers can accurately predict how the Electric Power EP9543126VVP cell will behave under various operating conditions. This allows for the selection of the most suitable cells based on their thermal performance and energy output across the entire duty cycle. For instance, modelling can help identify the optimal charging protocols that prevent overheating while maximising charge rates. Furthermore, simulations can assess the usable energy and predict the state of charge (SoC) under different environmental conditions, ensuring that drones can reliably complete missions without mid-air failures. This data-driven approach reduces the risks associated with trial-and-error testing and enhances overall UAV mission readiness.
