Benchmarking Bidirectional On-Board Chargers via Power-Architecture and Control-Method Characterization: Towards V2X Applications Kuntal Mandal･Xavier Genaro-Munoz･Edgar Zahonero-Zahonero･Javier A. Corea-Araujo (IDIADA Automotive Technology) This paper outlines a workflow for calibrating and validating on-board charger (OBC) benchmark methodologies by instrumenting and measuring accessible input and output waveforms. The approach enables reproduction of under voltages, voltage distortions, instantaneous breakdowns, transient lows, and AC-side fluctuations, including harmonic composites. The key contribution is the identification of hardware architecture and control method to support performance enhancement, robust operation under extreme grid conditions, and evaluation of bidirectional capability. The analysis focuses on understanding OBC control impact on V2G, V2L, V2V, V2B and V2H configurations. Standard test signals and harmonic analysis characterize modulation and control methods for exploring design improvements for future high-efficiency and grid-interactive bidirectional chargers. |
