Stochastic model of Lithium-ion Batteries based on Polynomial Chaos Expansion

Abstract

Lithium-ion battery pack performance and longevity can be severely affected by cell-to-cell variations. Statistical modeling is an important tool for optimization of performance and safety of battery packs. In this work a statistical model of Lithium-ion battery cell, based on Polynomial Chaos Expansion is developed. Performance are compare with Monte Carlo simulations.
