This information report provides an overview of a typical high voltage electric propulsion vehicle (xEV) and the associated on-board safety systems typically employed by OEM’s to protect these high voltage systems. The report aims to improve public confidence in xEV safety systems and dispel public misconceptions about the likelihood of being shocked by the high voltage system, even when the vehicle has been damaged. The report will document select high voltage systems used for xEV’s and describe safety systems employed to prevent exposure to the high voltage systems.

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. In this system boundary the parts of the battery charging system that are included for evaluation are the EVSE, the battery charger (BC), the system powering auxiliary loads, and the battery. It should be noted that this is a change from the original text of J2894/1, but it was essential for the purposes of system analysis to include all the elements, such as the EVSE, to evaluate efficiency and response to events. In terms of power quality and efficiency, the effects of this change should be minor. Note that no distinction is made about the battery or the auxiliary loads, which may include fans, chillers, or other thermal management devices. Note that some systems may require multiple measurement points to capture all auxiliary loads.Technology -

This document describes the details of the Smart Energy Profile 2.0 (SEP2.0) communication used to implement the functionality described in the SAE J2836-1 use cases. Each use case subsection includes a description of the function provided, client device requirements, and sequence diagrams with description of the steps. Implementers are encouraged to consult the SEP2.0 schema and application specification for further details. Where relevant, this document notes, but does formally specify, interactions between the vehicle and vehicle operator.

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.
This is the 1st version of this document and completes step 1 effort that captures the initial objectives of the SAE task force. The intent of step 1 was to record as much information on “what we think works” and publish. The effort continues however, to step 2 that allows public review for additional comments and viewpoints, while the task force also continues additional testing and early implementation. Results of step 2 effort will then be incorporated into updates of this document and lead to a republished version.Technology -

This SAE Information Report J2836 establishes the instructions for the documents required for the variety of potential functions for PEV communications, energy transfer options, interoperability and security. This includes the history, current status and future plans for migrating through these documents created in the Hybrid Communication and Interoperability Task Force, based on functional objective (e.g., (1) if I want to do V2G with an off-board inverter, what documents and items within them do I need, (2) What do we intend for V3 of SAE J2953, …).

This SAE Recommended Practice is intended as a guide toward standard practice and is subject to change to keep pace with experience and technical advances. It describes a body of tests which may be used as needed for abuse testing of electric or hybrid electric vehicle Rechargeable Energy Storage Systems (RESS) to determine the response of such electrical energy storage and control systems to conditions or events which are beyond their normal operating range.
Abuse test procedures in this document are intended to cover a broad range of vehicle applications as well as a broad range of electrical energy storage devices, including individual RESS cells (batteries or capacitors), modules and packs. This document applies to vehicles with RESS voltages above 60 volts. This document does not apply to RESS that uses mechanical devices store energy (e.g., electro-mechanical flywheels).Technology -

This SAE Recommended Practice describes the vibration durability testing of a single battery (test unit) consisting of either an electric vehicle battery module or an electric vehicle battery pack. For statistical purposes, multiple samples would normally be subjected to such testing. Additionally, some test units may be subjected to life cycle testing (either after or during vibration testing) to determine the effects of vibration on battery life. Such life testing is not described in this procedure; SAE J2288 may be used for this purpose as applicable. Finally, impact testing, such as crash and pothole, is not included in this procedure.
