From Electrode to Pack: Simulate and Tune Fast Charge Profiles
Dr. Lorenzo Nicoletti, Application Engineer, MathWorks
The charging time of battery electric vehicles (BEVs) is crucial for consumer appeal, reducing range anxiety, and enhancing usability. However, fast charging can lead to faster battery wear and reduce the battery lifetime.
To hinder cell wear while obtaining optimal charging rates, various factors at the microscopic cell level must be considered. Furthermore, system level considerations like charger limits, thermal management design, control strategies, and manufacturing differences must be taken into account. All these requirements can be considered by calculating the fast charging profile, which ensures optimal charging time while reducing the risk of cell wear.
In this presentation, learn how to use Simscape Battery™ to set up an electrochemical model of a lithium-ion cell. Subsequently, you will discover how to extend this model to a parallel assembly and then a module while considering the thermal, electrical, and chemical behavior of the cells. The models will be employed to derive safe fast charge profiles for different charging scenarios.
