The SAE International Hybrid Communication and Interoperability Task Force has completed an extensive revision of SAE Standard J2847/2: Communication Between Plug-in Vehicles and Off-Board DC Chargers.
This update is the first step towards the goal of enabling EV and charging station providers to use the same communication code for bidirectional DC charging, including Vehicle-to-Grid (V2G) and Vehicle-to-Home (V2H) applications.
The update also identifies requirements for the home that should be considered, including the addition of an Automatic Transfer Switch to the electrical panel (the same as a home generator would require); and a Home Balancing Transformer, since the home is no longer connected to the utility transformer to balance the 120 VAC phase circuits.
Like all SAE standards, this one will continue to be updated as regulations and customer expectations continue to evolve. Companies that wish to join SAE’s EV standards efforts should contact Dante Rahdar, Ground Vehicle Committee Manager.
Meanwhile, SAE Industry Technologies Consortia (SAE ITC) has launched the Electric Vehicle Public Key Infrastructure (EVPKI) Consortium. EVPKI will be an industry-led and SAE-ITC managed group, with the mission of creating an inclusive framework for secure digital trust across the electric mobility PKI ecosystem.
Consortium deliverables include a PKI Certificate Policy, Platform Requirements Document and PKI Prototype.
SAE ITC has been designing and testing the SAE EVPKI Platform in a pre-competitive project that includes EV OEMs, charging manufacturers and other members of the EV ecosystem.
“SAE ITC is pleased to transition the EVPKI research program to industry consortium,” said Fabian Koark, CEO of SAE ITC. “The consortium will lead the implementation of secure bidirectional charging by establishing an inclusive, worldwide, protocol-neutral EV charging industry PKI platform. The members will define a market with high quality of service around certificate providers, while ensuring a high level of user experience and interoperability.”
The Consortium is open to private companies and public sector organizations that recognize the need for a secure bidirectional charging solution. SAE ITC encourages interested stakeholders to inquire about membership.
