Parameterization of Equivalent Circuit Models for High Power Lithium-Ion Batteries in HEV Applications
Paper in proceedings, 2016
Three different linear equivalent electrical circuit models for power optimized lithium-ion batteries are parameterized and compared in a long dynamic load cycle representing typical hybrid electric vehicle usage. The goal is to estimate the voltage on the battery terminals by only using an open-loop electrical model. Model parameters are extracted trough a simple discharge pulse test and the parameter results are presented for five different types of batteries. A quantification of the model fit is presented and compared with similar studies.
