Characterising Lithium-Ion Battery Degradation through the Identification and Tracking of Electrochemical Battery Model Parameters

This work presents the framework for an ageing diagnostic tool based on identifying and then tracking the evolution of model parameters of a fundamental electrochemistry-based battery model from non-invasive voltage/current cycling tests.

This technical paper will explore:

  • The minimization of the computational resources required for optimizing a large parameter set.
  • The mathematical formulation of a P2D model and the model parameters.
  • Ageing stress factors and ageing mechanisms.
  • The potential causality between cell degradation as a function of calendar ageing.
