Power-Limit Estimation for Lithium Ion Batteries Using Physics-Based Models and Predictive Methods

摘要

1. Physics-based models provide key information on electrochemical dynamics that can be used to achieve important control objectives 2. FOMs are too complex for real-time implementation, but techniques have been developed to create simpler and faster ROMs 3. Model predictive control can exploit the simpler models to implement realtime power-limit estimation based on real electrochemical bounds 4. Continuing research aims to expand models to include internal thermal properties and further mechanisms of degradation 5. Upcoming phase of research will pursue cell-based laboratory experiments to validate simulation results.
