Megawatt Charging System for Electric Vehicles
2021-12-15
WIP
J3271
This document describes the megawatt-level DC charging system requirements for couplers/inlets, cables, cooling, communication and interoperability. The intended application is for commercial vehicles with larger battery packs requiring higher charging rates for moderate dwell time. A simplified analog safety signaling approach is used for connection-detection to guarantee de-energized state for unmated couplers with superimposed high speed data for EVSE-EV charging control and other value added services.

Dynamic Wireless Power Transfer for both Light and Heavy Duty Vehicles (SAE RP J2954/3)
2023-04-20
WIP
J2954/3
The SAE J2954 standard establishes an industry-wide specification that defines acceptable criteria for Light Duty EVs and SAE RP J2954/2 establishes the same for Heavy Duty. SAE RP SAE J2954. SAE RP J2954/3 establishes interoperability, electromagnetic compatibility, EMF, minimum performance, safety, and testing for dynamic wireless power transfer (D-WPT) of both light and heavy duty plug-in electric vehicles. The specification defines various charging levels that are based on the levels defined for SAE J1772 conductive AC charge levels as SAE J2954/1 & SAE J2954/2 with some variations. A standard for WPT based on these charge levels enables selection of a charging rate based on vehicle requirements, thus allowing for better vehicle packaging and ease of customer use. SAE J2954/3 addresses unidirectional charging, from grid to vehicle; bidirectional energy transfer may be evaluated for a future standard.

Utility Factor Definitions for Plug-In Hybrid Electric Vehicles Using Travel Survey Data
2019-06-25
WIP
J2841
The total fuel and energy consumption rates of a Plug-In Hybrid Electric Vehicle (PHEV) vary depending upon the distance driven. For PHEVs, the assumption is that operation starts in battery charge-depleting mode and eventually changes to battery charge-sustaining mode. Total distance between charge events determines how much of the driving is performed in each of the two fundamental modes. An equation describing the portion of driving in each mode is defined. Driving statistics from the National Highway Transportation Survey are used as inputs to the equation to provide an aggregate "Utility Factor" (UF) applied to the charge-depleting mode results.

Power Quality Test Procedures for Plug-In Electric Vehicle Chargers
2019-08-27
WIP
J2894/2
This recommended practice provides test procedures for evaluating PEV chargers for the parameters established in SAE J2894/1, Power Quality Requirements for Plug-In Electric Vehicle Chargers. In addition, this Recommended Practice provides procedures for evaluating EVSE/charger/battery/vehicle systems in terms of energy efficiency, which is a subset of power quality. This expansion of scope from J2894/1 was requested by the stakeholders, and it provides relevance to the system level analyses that are current in state and federal processes. In accordance, the scope includes the energy storage system and the input and output of that system.

In consideration of evaluation, a system boundary is established. The system boundary defines the tested elements and the measurement points. The system boundary for most of the systems expected to be evaluated under this Recommended Practice is shown in Figure 1.

WIP
J2894/1
The intent of this document is to develop a recommended practice for PEV chargers, whether on-board or off-board the vehicle, that will enable equipment manufacturers, vehicle manufacturers, electric utilities, and others to make reasonable design decisions regarding power quality. The three main purposes are as follows: 1. To identify those parameters of PEV battery charger that must be controlled in order to preserve the quality of the AC service. 2. To identify those characteristics of the AC service that may significantly impact the performance of the charger. 3. To identify those characteristics of the AC service that may significantly impact the performance of the charger. SAE J2894/2 will describe the test methods for the parameters/requirements in this document.

Interconnection Requirements for Onboard, Grid Support Inverter Systems
2023-03-31
WIP
J3072
This SAE J3072 Standard establishes requirements for a grid support inverter system function which is integrated into a plug-in electric vehicle (PEV) which connects in parallel with an electric power system (EPS) by way of conductively coupled, electric vehicle supply equipment (EVSE). This standard also defines the communication between the PEV and the EVSE required for the PEV onboard inverter function to be configured and authorized by the EVSE for discharging at a site. The requirements herein are intended to be used in conjunction with IEEE 1547 and IEEE 1547.1. This standard shall also support interactive inverters which conform to the requirements of IEEE 1547-2003 and IEEE 1547.1-2005, recognizing that many utility jurisdictions may not authorize interconnection.

Communication for Wireless Power Transfer Between Light-Duty Plug-in Electric Vehicles and Wireless EV Charging Stations
2022-10-09
WIP
J2847/6

SAE J2847/6 establishes minimum requirements for communication between an electric vehicle and an inductive battery charging system for wireless power transfer (WPT). Where relevant, this document notes—but does not formally specify—interactions between the vehicle and vehicle operator.

This document leverages the work of the SAE J2954 Alignment and Controls Sub-Team in the Wireless Power Transfer and Alignment Task Force by extending a JSON-based message set (protocol) originally developed to bench test wireless energy transfer interoperability between unmatched Ground Assembly (GA) and Vehicle Assembly (VA) systems (i.e., components manufactured by different companies). SAE J2847/6 furthers that work by adding messages sufficient to indicate that proper coil alignment has been achieved, initialize the sub-systems for wireless charging, ramp-up to full power, perform active wireless power transfer, and terminate the WPT session.

Wireless Power Transfer for Light-Duty Plug-in/Electric Vehicles and Alignment Methodology
2023-09-18
WIP
J2954
The SAE J2954 standard establishes an industry-wide specification that defines acceptable criteria for interoperability, electromagnetic compatibility, EMF, minimum performance, safety, and testing for wireless power transfer (WPT) of light-duty plug-in electric vehicles. The specification defines various charging levels between WPT 1-3 (3.7kVA to 11.1kVA). A standard for WPT based on these charge levels enables selection of a charging rate based on vehicle requirements, thus allowing for better vehicle packaging and ease of customer use. The specification supports home (private) charging and public wireless charging also establishing a universal Ground Assembly WPT 3 (GA) at 11.1kVA which is interoperable to Vehicle Assemblies (VA) WPT 1-3. SAE J2954 contains requirements for safety, performance, and interoperability of WPT. It also contains recommended methods for evaluating electromagnetic emissions, but the requirements and test procedures are controlled by regulatory bodies.

Standard Four-Letter Coding as an Identification Method for Alternative Fuel Vehicles
2024-05-07
WIP
J3108/1
SAE J3108 RP provides fuel and hazard guidance for first and second responders of incidents associated with alternative fueled vehicles. The intent of this SAE J3108-1 RP is to remain with the limited number of seven intuitive and colored letters contained in each of the first two letter positions (72=49). However, the use of four letters plus nine digits (to not use either 0 or o) permits up to 1185921 unique identifiers (334) for future expansion. The RP is not intended to replace the standards for SAE J2990 format emergency response guide (ERG) created by automotive manufacturers for use at the scene of an emergency. Automotive OEMs are encouraged to reference this RP for industry design guidance when creating vehicle requirements and ERGs. This coding should be consistent with other vehicle badging with the goal of providing additional clarity.
