context_page_description: SAE J1772, also known as a J plug, is a North American standard for electrical connectors for electric vehicles maintained by the SAE International and has the formal title "SAE Surface Vehicle Recommended Practice J1772, SAE Electric Vehicle Conductive Charge Coupler". It covers the general physical, electrical, communication protocol, and performance requirements for the electric vehicle conductive charge system and coupler. The intent is to define a common electric vehicle conductive charging system architecture including operational requirements and the functional and dimensional requirements for the vehicle inlet and mating connector.
context_section_description: The main stimulus for the development of SAE J1772 came from the California Air Resources Board (CARB). Formerly electric vehicles like the General Motors EV1 had used inductive charger couplers. These were ruled out in favor of conductive coupling to supply electricity for recharging with the board settling upon the SAE J1772-2001 standard  as the charging interface for electric vehicles in California in June 2001. Avcon manufactured a rectangular connector compliant with specification SAE J1772 REV NOV 2001, capable of delivering up to 6.6 kW of electrical power.)
  The CARB regulation of 2001 mandated the usage of SAE J1772-2001 beginning with the 2006 model year. Later requirements asked for higher currents to be used than the Avcon connector could provide. This process led to the proposal of a new round connector design by Yazaki which allows for an increased power delivery of up to 19.2 kW delivered via single phase 120–240 V AC at up to 80 amperes. In 2008 the CARB published a draft amendment to Title 13 section 1962.2 that mandated the usage of the oncoming SAE J1772 standard beginning with the 2010 model year; this was approved in 2012.
  The Yazaki plug that was built to the new SAE J1772 plug standard successfully completed certification at UL. The standard specification was subsequently voted upon by the SAE committee in July 2009. On January 14, 2010 the SAE J1772 REV 2009 was adopted by the SAE Motor Vehicle Council. The companies participating in or supporting the revised 2009 standard include smart, Chrysler, GM,  Ford, Toyota, Honda, Nissan, and Tesla.
  The SAE J1772-2009 connector specification has been added to the international IEC 62196-2 standard (“Part 2: Dimensional compatibility and interchangeability requirements for a.c. pin and contact-tube accessories”) with voting on the final specification to close in May 2011. The SAE J1772 connector is considered a “Type 1” implementation providing a single phase coupler.
