This paper is the first in a series of documents designed to record the progress of the SAE J2293 Task Force as it continues to develop and refine the communication requirements between Plug-In Electric Vehicles (PEV) and the Electric Utility Grid. In February, 2008 the SAE Task Force was formed and it started by reviewing the existing SAE J2293 standard, which was originally developed by the Electric Vehicle (EV) Charging Controls Task Force in the 1990s. This legacy standard identified the communication requirements between the Electric Vehicle (EV) and the EV Supply Equipment (EVSE), including off-board charging systems necessary to transfer DC energy to the vehicle. It was apparent at the first Task Force meeting that the communications requirements between the PEV and utility grid being proposed by industry stakeholders were vastly different in the type of communications and messaging documented in the original standard.
Contemporary air traffic management (ATM) challenges are both (1) acute and (2) growing at rates far outpacing established ways for absorbing technological innovation. Lack of timely response will guarantee failure to meet demands. Immediately that creates a necessity to identify means of coping and judging new technologies based on possible speed of adoption. Paralleling the challenges are developments in capability, both recent and decades old. Some steps (e.g., Global Positioning System (GPS) backup) are well known and, in fact, should have progressed further long ago. Others (e.g., sharing raw measurements instead of position fixes) are equally well known and, if followed by further flight tests initiated (and successful) years ago, would have produced a wealth of in-flight experience by now if development had continued. Other possibilities (e.g., automated pilot override) are much less common and are considered largely experimental.
This SAE Information Report SAE J2931 establishes the requirements for digital communication between Plug-In Electric Vehicles (PEV), the Electric Vehicle Supply Equipment (EVSE) and the utility or service provider, Energy Services Interface (ESI), Advanced Metering Infrastructure (AMI) and Home Area Network (HAN). This is the third version of this document and completes the effort that specifies the digital communication protocol stack between Plug-in Electric Vehicles (PEV) and the Electric Vehicle Supply Equipment (EVSE). The purpose of the stack outlined in Figure 1 and defined by Layers 3 to 6 of the OSI Reference Model (Figure 1) is to use the functions of Layers 1 and 2 specified in SAE J2931/4 and export the functionalities to Layer 7 as specified in SAE J2847/2 (as of August 1, 2012, revision) and SAE J2847/1 (targeting revision at the end of 2012).
As mobility software becomes increasingly complex and connected, so does the risk of human error and system safety. To combat this, New York-based software company AdaCore will work with Nvidia Corporation of Santa Clara, California to apply open-source Ada and SPARK programming languages for select software security firmware elements in highly-complex, safety-critical systems like Nvidia’s DRIVE AGX automated and autonomous vehicle solutions.
In the next decade, commercial aviation will see Next Generation ATM (NextGEN), Single European Skies ATM Research (SESAR), and others utilizing Internet- based air-to-ground communication links for advanced “air traffic control” (ATC) communications. Commercial Aviation Cyber Security: Current State and Essential Reading highlights some of the major issues the industry must confront if the vision of a new, advanced air traffic management is to come to fruition. This will require standardization work to identify key components with built-in cyber security that will guide prototype testing, functionality, and prioritizing implementation efforts to solve the roadblocks to global interoperability. The ten technical papers selected for Commercial Aviation Cyber Security: Current State and Essential Reading span the last decade’s work in commercial aviation cyber security, and aircraft cyber technologies.
Through this work, Wind River and Airbiquity look to enable secure and intelligent software updates and data management for these vehicles through over-the-air (OTA) programming technology. The work may also lead to similar solutions for traditional aerospace and unmanned aircraft system (UAS) industries.
The China Automotive Technology and Research Center Co., Ltd. (CATARC), TÜV SÜD Group, and Shanghai SH Intelligent Automotive and International Transportation Innovation Center (ITIC) have joined with SAE International to establish the International Alliance for Mobility Testing and Standardization (IAMTS).
TIoTA, an open software consortium of over 50 members organized to support the creation of a secure, scalable, interoperable, and trusted IoT ecosystem, began the E-Mobility Challenge to link IoT devices with consumers and stakeholder companies such as operators and service, communication, and payment providers within the preexisting European electric vehicle ecosystem.
