A Feedback Interpretation of the Doyle-Fuller-Newman Lithium-Ion Battery Model

The Doyle-Fuller-Newman "psuedo-2-D" electrochemical model of a lithium-ion battery is shown to have a feedback structure when electric double-layer effects are included. This opens the possibility for the model to be rigorously analyzed using input-output systems theory. Several immediate...

Zusammenfassung:	The Doyle-Fuller-Newman "psuedo-2-D" electrochemical model of a lithium-ion battery is shown to have a feedback structure when electric double-layer effects are included. This opens the possibility for the model to be rigorously analyzed using input-output systems theory. Several immediate consequences of the feedback structure are discussed, including observability and well-posedness issues, and an application to reduced-order modeling is described.
