Development and Implementation of SAE J2953 for AC Charging

2014-04-01
2014-01-0184
The purpose of this paper is to outline the development and implementation of SAE J2953. SAE J2953 contains the requirements and procedures of interoperability testing. Within SAE J2953 interoperability test articles are defined as an Electric Vehicle Supply Equipment (EVSE) paired with a Plug-in Electric Vehicle (PEV). SAE J2953 requires the development and application of test fixtures with the ability to monitor mechanical forces and electrical signals of a charge system without modification or disassembly of the EVSE and PEV under test. Electrical signal monitoring includes pilot, proximity, and line conductors of the SAE J1772 TM AC coupler. This paper will outline the requirements of the fixtures as well as a specific build. Data will be presented showing full implementation of the SAE J2953 procedures including root-cause analysis and standards gap discovery.

This paper outlines the development and progress of implementing the SAE J2931, J2847/2 and J1772 communication standards to accomplish off-board DC charging. Communication between the off-board DC Electric Vehicle Supply Equipment (EVSE) and Plug-in Electric Vehicle (PEV) occurs on the pilot wire of the SAE J1772 connector via HomePlug Green PHY power line communication (PLC). An Electric Vehicle Communication Controller (EVCC) was developed to interface with the PEV's Battery Energy Control Module (BECM). A Supply Equipment Communication Controller (SECC) was also developed to interface with the DC EVSE's Power Control Module (PCM). Firmware was developed to implement the SAE J2931/1 communication stack, which is harmonized with the ISO/IEC DIS 15118-2 and DIN 70121 standards for DC charging communication.
