DC Fast Charging Test Procedures

This report has been drafted as an initial effort to develop a standardized test procedure for DC Fast Charging (DCFC) for Light-duty (LD) Electric Vehicles (EVs). The proposed test procedures are designed to be time-efficient, aligned with EV discharge tests, and practical to implement, thereby minimizing the testing and computational efforts required by Original Equipment Manufacturers (OEMs) and testing authorities. This document builds upon Society of Automotive Engineers (SAE) SAE J2953-4 and International Organization for Standardization (ISO) 12906:2024 EV charging procedures, while also incorporating DCFC testing experience obtained through the EV@Scale Next Gen Profiles Project (NGP) project conducted at Argonne National Laboratory. The proposed draft seeks to harmonize the EV discharge methodology defined in SAE J1634 or a similar standardized EV discharge procedure with EV fast charging procedures, enabling their sequential execution. This integration is intended to streamline EV testing, thereby reducing both test duration and effort. In addition, this draft includes the requirements and specifications on measurement points for the EV Supply Equipment (EVSE) and EV. These locations are explicitly illustrated to ensure clarity regarding where measurements must be performed. A secondary objective of this effort is to address the needs of the EV testing community. By leveraging internationally recognized discharge and DCFC standards, this draft proposes a consistent test procedure that produces standardized, repeatable fast charging performance testing data based on measurable output rather than relying on vehicle-reported information. While methodologies for DCFC performance metric definition and calculation may differ across regions, the harmonized data acquisition framework proposed here is intended to assist comparability and consistency worldwide. The recommendations provide an approach to capturing repeatable DCFC performance characteristics measured at the vehicle battery. While the current measurements focus on core vehicle parameters, we acknowledge the potential value of future research to include more EVSE performance data.
