Charging Standards

The following is a list of current standards (as of early 2022) concerning the various aspects of EV charging, connected and wireless. 
More work is needed, first to adjust to an ever-changing technology, and second and importantly to promote interoperability, simplicity,
and safe operation.

SAE J3072 AC Grid Interconnection Interconnection requirements for a utility-interactive inverter system which is integrated into a plug-in electric vehicle (PEV) and connects in parallel with an electric power system (EPS) by way of conductively-coupled, electric vehicle supply equipment (EVSE). This standard also defines the communication between the PEV and the EVSE required for the PEV onboard inverter to be configured and authorized by the EVSE for discharging at a site. The requirements herein are intended to be used in conjunction with IEEE 1547 Standard for Interconnecting Distributed Resources with Electric Power Systems and IEEE 1547.1 Standard for Conformance Test Procedures for Equipment Interconnecting Distributed Resources with Electric Power Systems.
SAE J2847/3_202103 AC Communication for Plug-in Vehicles as a Distributed Energy Source: This document applies to a plug-in electric vehicle (PEV) which is equipped with an onboard inverter and communicates using IEEE 2030.5-2018. It is a supplement to the SEP2 standard, which supports the use cases defined by SAE J2836/3. It provides guidance for the use of the SEP2 distributed energy resource function set with a PEV. It also provides guidance for the use of the SEP2 flow reservation function set, when used for discharging. It is not intended to be a comprehensive guide to the use of SEP2 in a PEV.
IEC 61851-1, 3rd edition 2017 AC, DC Safety and Functional Electric vehicle conductive charging system - Part 1: General requirements; Applies to EV supply equipment for charging electric road vehicles, with a rated supply voltage up to 1 000 V AC or up to 1 500 V DC and a rated output voltage up to 1 000 V AC or up to 1 500 V DC. 
SAEJ1772, IEC 62196 AC, DC Safety and Functional General physical, electrical, functional and performance requirements to facilitate conductive charging of EV/PHEV vehicles in North America. This document defines a common EV/PHEV and supply equipment vehicle conductive charging method including operational requirements and the functional and dimensional requirements for the vehicle inlet and mating connector.
CharIN-CCS AC, DC Interoperability & Conformance interoperability based on the Combined Charging System (CCS)
SAE J2894/1-201901 AC, DC Grid Interconnection Power Quality Requirements for Plug-In Electric Vehicle Chargers: 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:
  • To identify those parameters of PEV battery charger that must be controlled in order to preserve the quality of the AC service
  • To identify those characteristics of the AC service that may significantly impact the performance of the charger.
  • To identify values for power quality, susceptibility, and power control parameters that 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_201503  AC, DC Grid Interconnection Power Quality Test Procedures for Plug-In Electric Vehicle Chargers: 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.

  • is of dry or liquid-filled construction;
  • has a rated voltage not exceeding 1500 V; and
  • is for commercial, industrial, and residential indoor and outdoor use in non-hazardous locations in accordance with the Rules of CSA C22.1, Canadian Electrical Code, Part I.
