Technical committeeTypeAcronymSAE J3105Published year2020KeywordsDescription
This document covers the general physical, electrical, functional, testing, and performance requirements for conductive power transfer, primarily for vehicles using a conductive ACD connection capable of transferring DC power. It defines conductive power transfer methods, including the infrastructure electrical contact interface, the vehicle connection interface, the electrical characteristics of the DC supply, and the communication system. It also covers the functional and dimensional requirements for the vehicle connection interface and supply equipment interface. There are also sub-documents which are identified by a SAE J3105/1, SAE J3105/2, and SAE J3105/3. These will be specific requirements for a specific interface defined in the sub-document.

This document covers the general physical, electrical, functional, testing, and performance requirements for conductive power transfer to an Electric Vehicle using a Coupler capable of, but not limited to, transferring three-phase AC power. It defines a conductive power transfer method including the digital communication system. It also covers the functional and dimensional requirements for the Electric Vehicle Inlet, Supply Equipment Connector, and mating housings and contacts. Moveable charging equipment such as a service truck with charging facilities are within scope. Charging while moving (or in-route-charging) is not in scope.

Technical committeeTypeAcronymSAE J2990-2Published year2020KeywordsDescription
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.

Technical committeeTypeAcronymSAE J2894-2Published year2015KeywordsDescription
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 -
