Localized reduced basis approximation of a nonlinear finite volume battery model with resolved electrode geometry

Abstract

In this contribution we present first results towards localized model order reduction for spatially resolved, three-dimensional lithium-ion batterymodels. We introduce a localized reduced basis scheme based on non-conforming local approximation spaces stemming from a finite volume discretization of the analytical model and localized empirical operator interpolation for the approximation of the model’s nonlinearities. Numerical examples are provided indicating the feasibility of our approach.
