摘要:AbstractThe design of optimal fast charging strategies for lithium-ion batteries that can significantly reduce the charging time while managing multiple conflicting objectives is crucial for widespread adoption of electric vehicles. In this paper, a novel methodology is introduced to define optimal control policies for fast charging. The proposed approach utilizes a physics-based electrochemical model to accurately predict the cell’s electrical, thermal, and aging response, in conjunction with particle swarm optimization (PSO). The optimization is performed offline to manage mathematical complexity and the results are analyzed to define a Pareto-optimal front for the multi-objective optimization (aging versus time over a given charging cycle) considering different power limitations for the thermal management system. These results indicate how optimal thermal management is critical to tradeoff the competing objectives of charging time and degradation.
