| Abstract(E) | It is important to establish and standardize a method to measure and evaluate the electrical characteristics of EV traction batteries mounted on EVs as an inspection methodology for EV performance and safety. In this study, multiple methods for measuring the internal resistance (impedance) of battery packs mounted on EVs were evaluated. The experiment results and comparative investigation are reported, to propose an appropriate and versatile method. A method for directly measuring the voltage and impedance of EV traction batteries through the rapid (DC) charging port is reported. The principles and verification results of this approach are presented. A methodology for assessing and managing battery state, based on physical quantities obtained through this method, is proposed with the aim of ensuring secure long-term EV usage and maximizing the value of the batteries, thereby contributing to the realization of a sustainable circular economy. |
