xEV Labels to Assist First and Second Responders, and Others

2017-03-02
CURRENT
J3108_201703
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

2019-04-26
WIP
J2954
The Standard SAE J2954 establishes an industry-wide specification that defines acceptable criteria for interoperability, electromagnetic compatibility, EMF, minimum performance, safety, and testing for wireless charging of light-duty electric and plug-in electric vehicles. A standard for wireless power transfer (WPT) based on the charge levels from WPT 1-3 (3.7-11 kW) 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. The SAE Standard J2954 addresses unidirectional charging, from grid to vehicle; bidirectional energy transfer may be evaluated for a future standard. This Standard is intended to be used in stationary applications (charging while vehicle is not in motion); dynamic applications may be considered in the future.

J2954_201904
The Recommended Practice SAE J2954 establishes an industry-wide specification that defines acceptable criteria for interoperability, electromagnetic compatibility, EMF, minimum performance, safety, and testing for wireless charging of light-duty electric and plug-in electric vehicles. The specification defines various charging levels that are based on the levels defined for SAE J1772 conductive AC charge levels 1, 2, and 3, with some variations. A standard for wireless power transfer (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. In the near term, vehicles that are able to be charged wirelessly under Recommended Practice SAE J2954 should also be able to be charged by SAE J1772 plug-in chargers.

Vehicle-mounted Pantograph (Bus Up) Connection

WIP
J3105/2
This document details one of the connections of the J-3105 document. The connections are referenced in the scope of the main document J-3105. J-3105-2 details the Vehicle-mounted Pantograph or the Bus-up connection. All the common requirements are defined in the main document and this document provides for the details of the connection. This document covers the connection interface relevant requirements for an electric vehicle power transfer system using a conductive automated charging device based on a conventional rail vehicle pantograph design. In order to allow interoperability for on-road vehicles (in particular buses and coaches) one configuration is being described in this document. Other configurations may be used for non-standard applications (e.g. mining trucks or port vehicles).

Vehicle Power Test for Electrified Powertrains

2017-09-19
CURRENT
J2908_201709
This document provides test methods for evaluating the maximum power of electrified vehicle powertrain systems by direct measurement at the drive wheel hubs or axles. Additional tests are included specifically for PHEVs to measure electric-only propulsion power and for HEVs to measure electric power assist and regenerative braking. The testing requires either a chassis or hub dynamometer for all driven wheels. Results are processed to provide fair and consistent comparisons of power capabilities among different designs of electrified powertrains. Tests can also be performed on conventional vehicles if precise comparisons to electrified vehicles are desired.

Utility Factor Definitions for Plug-In Hybrid Electric Vehicles Using Travel Survey Data

CURRENT
J2841_201009
This SAE Information Report establishes a set of “Utility Factor” (UF) curves and the method for generating these curves. The UF is used when combining test results from battery charge-depleting and charge-sustaining modes of a Plug-in Hybrid Electric Vehicle (PHEV). Although any transportation survey data set can be used, this document will define the included UF curves by using the 2001 United States Department of Transportation (DOT) “National Household Travel Survey” and a supplementary dataset.

Utility Factor Definitions for Plug-In Hybrid Electric Vehicles Using 2001 U.S. DOT National Household Travel Survey Data

J2841_200903
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.

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

J2836/6
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.
