WIP
J3108
This recommended practice prescribes clear and consistent labeling methodology for communicating important xEV high voltage safety information. Examples of such information include identifying key high voltage system component locations and high voltage disabling points. These recommendations are based on current industry best practices identified by the responder community. Although this recommended practice is written for xEVs with high voltage systems, these recommendations can be applied to any vehicle type.

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.

Use Cases for Wireless Charging Communication for Plug-in Electric Vehicles

CURRENT
J2836/6_202104
This SAE Information Report SAE J2836/6 establishes use cases for communication between plug-in electric vehicles and the EVSE for wireless energy transfer as specified in SAE J2954. It addresses the requirements for communications between the on-board charging system and the wireless EV supply equipment (WEVSE) in support of detection of the WEVSE, the charging process, and monitoring of the charging process. Since the communication to the charging infrastructure and the power grid for smart charging will also be communicated by the WEVSE to the EV over the wireless interface, these requirements are also covered. However, the processes and procedures are expected to be identical to those specified for V2G communications specified in SAE J2836/1. Where relevant, the specification notes interactions that may be required between the vehicle and vehicle operator, but does not formally specify them.

This SAE Information Report SAE J2836/2™ establishes use cases and general information for communication between plug-in electric vehicles and the DC Off-board charger. Where relevant, this document notes, but does not formally specify, interactions between the vehicle and vehicle operator. This applies to the off-board DC charger for conductive charging, which supplies DC current to the vehicle battery of the electric vehicle through a SAE J1772™ Hybrid coupler or SAE J1772™ AC Level 2 type coupler on DC power lines, using the AC power lines or the pilot line for PLC communication, or dedicated communication lines that is further described in SAE J2847/2. The specification supports DC energy transfer via Forward Power Flow (FPF) from grid-to-vehicle. The relationship of this document to the others that address PEV communications is further explained in section 5.

Standard Four-Letter Coding as an Identification Method for Alternative Fuel Vehicles

J3108/1_202403
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.

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 values for power quality, susceptibility and power control parameters which are based on current U.S. and international standards. These values should be technically feasible and cost effective to implement into PEV battery chargers. SAE J2894/2 Power Quality Requirements for Plug-In Electric Vehicle Chargers – Test Methods will describe the test methods for the parameters / requirements in this document.
