Abstract

This study analyzed the SOC-voltage characteristics of high-voltage batteries and proposed methods and criteria for evaluating SOC and voltage during EV conversion tuning inspections. Regression analysis of collected data on SOC and voltage changes during the charging process revealed a very high correlation. In particular, the linearity of the data measured in slow charging mode was found to be stable and constant. Therefore, tuning inspection criteria for SOC and voltage can be established by considering the linear model and tolerances analyzed in slow charging mode, and the normal operation of the signal can be evaluated based on these criteria.
