 This paper provides an overview of various battery modeling techniques and compares them with respect to accuracy and execution time. The four modeling techniques include a combined model, two RC equivalent circuit models, a single particle model, and a support vector machine model. The combined model was found to provide the best accuracy while the support vector machine model provided the fastest execution time.
