Evaluation of Battery Models for Prediction of Electric Vehicle Range

摘要

The objective of this investigation was to evaluate three different battery analysts models for predicting electric vehicle battery output and the corresponding electric vehicle range for various driving cycles as described by SAE-J227a. The approach assisted of using the models to predict output and range, then comparing the results with experimentally determined values. The latter were determined by laboratory ten on batteries, using discharge cycles identical to those encountered by an actual electric vehicle while on the SAE cycles. Results indicated that the so-called Modified Hoxie Model gave the best predictions with an accuracy of about 97-98% in." most cases and 86% in the worst case.
