Accurate Modeling of CCS Combo Type 1 Cable and Its Communication Performance Analysis for High-Speed EV-EVSE Charging System

This paper addresses the issue of electromagnetic interference (EMI) in electric vehicle supply equipment (EVSE) charging cables, which can disrupt communication signal for real-time monitoring status, leading to termination charging. We propose a dedicated measurement jig Combined Charging System Combo Type 1 (CCS-CT1) cable structure and models its electrical characteristics using impedance peeling technique de-embedding. The obtained pure S-parameters CCS-CT1 are then used conduct simulation integrity problem caused by Gaussian noise, is worst-case scenario that occur typical system. suggests root cause this may be related high-power AC/DC conversion device included EVSE, uses switch-mode power (SMPC) method involves nonlinear operation result increased harmonic noise more complex protocol precise control. Finally, study provides insights into challenges implementing high-speed systems offers solution obtaining accurate cables.
