This SAE Information Report establishes the Use Cases for communications and customer-focused Key Performance Indicators (KPI) between plug-in electric vehicles (PEVs) and their customers. The Use Case Scenarios define the information to be communicated related to customer convenience features for charge on/off control, charge power curtailment, customer preference settings, charging status, electric vehicle supply equipment (EVSE) availability/access, and electricity usage, plus customer information resulting from conflicts to charging preferences. It also addresses the KPI that can provide a uniform set of metrics to quantitively assess the charging experience. This document only provides the Use Cases that define the communications requirements to enable customers to interact with the PEV and the KPI to optimize their experience with charging a PEV. Specifications such as protocols and physical transfer methods for communicating information are not within the scope of this document.
This SAE Recommended Practice summarizes the conformance requirements for digital communication between the PEV and EVSE and establishes the interoperability requirements for successful charging sessions. This first version includes charging conformance summary for both the vehicle and EVSE and updates from CharIN with modifications, additions, and deletions to improve successful charging sessions. The summary of all existing charging/discharging standards, conformance, and functional categories will be updated in subsequent updates, and message/signal/values that would cause an interoperability issue will be clarified as this leads to diagnostic codes the vehicle/EVSE/Charge Point Operator and others can view to let the customer know what specific issue led to a failure to charge or discharge. This additional effort is ongoing and will be expanded in the next version update as this becomes more mature.
xEVs involved in incidents present unique hazards associated with the high voltage system (including the battery system). These hazards can be grouped into three categories: chemical, electrical, and thermal. The potential consequences can vary depending on the size, configuration, and specific battery chemistry. Other incidents may arise from secondary events such as garage fires and floods. These types of incidents are also considered in the recommended practice (RP). This RP aims to describe the potential consequences associated with hazards from xEVs and suggest common procedures to help protect emergency responders, tow and/or recovery, storage, repair, and salvage personnel after an incident has occurred with an electrified vehicle. Industry design standards and tools were studied and where appropriate, suggested for responsible organizations to implement. Lithium ion (Li-ion) batteries used for vehicle propulsion power are the assumed battery system of this RP. This chemistry is
This SAE Recommended Practice establishes the minimum interface compatibility requirements for electric vehicle (EV) inductively coupled charging for North America. This part of the specification is applicable to manually connected inductive charging for Levels 1 and 2 power transfer. Requirements for Level 3 compatibility are contained in Appendix B.

This type of inductively coupled charging is generally intended for transferring power at frequencies significantly higher than power line frequencies. This part of the specification is not applicable to inductive coupling schemes that employ automatic connection methods or that are intended for transferring power at power line frequencies.
This document was developed to provide a method of obtaining repeatable measurements that accurately reflects the performance of a propulsion electric drive subsystem, whose output is used in an electrified vehicle regardless of complexity or number of energy sources. The purpose is to provide a familiar and easy-to-understand performance rating. Whenever there is an opportunity for interpretation of the document, a good faith effort shall be made to obtain the typical in-service performance and characteristics and avoid finding the best possible performance under the best possible conditions. Intentional biasing of operating parameters or assembly tolerances to optimize performance for this test shall not be considered valid results in the scope of this document.

This document details one of the connections of the SAE J3105 document. The connections are referenced in the scope of the main document SAE J3105. SAE J3105/2 details the vehicle-mounted pantograph, or the bus-up connection. All the common requirements are defined in the main document; the current document provides 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. To allow interoperability for on-road vehicles (in particular, buses and coaches), one configuration is described in this document. Other configurations may be used for non-standard applications (for example, mining trucks or port vehicles).
SAE J2293 establishes requirements for Electric Vehicles (EV) and the off-board Electric Vehicle Supply Equipment (EVSE) used to transfer electrical energy to an EV from an Electric Utility Power System (Utility) in North America. This document defines, either directly or by reference, all characteristics of the total EV Energy Transfer System (EV-ETS) necessary to insure the functional interoperability of an EV and EVSE of the same physical system architecture. The ETS, regardless of architecture, is responsible for the conversion of AC electrical energy into DC electrical energy that can be used to charge the Storage Battery of an EV, as shown in Figure 1. The different physical ETS system architectures are identified by the form of the energy that is transferred between the EV and the EVSE, as shown in Figure 2. It is possible for an EV and EVSE to support more than one architecture. This document does not contain all requirements related to EV energy transfer, as there are many
The published SAE J2954 standard established an industry-wide specification that defines acceptable criteria for interoperability, electromagnetic compatibility, EMF, minimum performance, safety, and testing for wireless power transfer (WPT) for light-duty plug-in electric vehicles.
