VW, BMW and ChargePoint partner to create SAE Combo DC fast charging corridors on the East and West Coasts
January 22, 2015
In a major boost to the availability of public fast charging stations with SAE Combo connectors (J1772, earlier post), Volkswagen of America and BMW of North America, together with ChargePoint, the largest electric vehicle charging network, announced at the Washington Auto Show an initiative to create more express charging corridors along heavily-traveled routes on the East and West Coasts.
In the initial phase, the aim is to install nearly 100 DC Fast charging ports across both coasts, with plans to expand the program to increase access to fast charging across the country. The installations will occur both within and between relevant metro areas, strategically spaced at a maximum of 50 miles (80 km) apart. Each fast charging location along the express charging corridors is expected to include up to two 50 kW DC fast chargers or 24 kW DC fast chargers with the SAE Combo connector. The 50 kW fast chargers will also have a CHAdeMO connector available, according to Volkswagen, while the 24 kW units will be SAE Combo only, at least to start.
ANSI EV standards panel releases progress report on standardization activities
December 03, 2014
The American National Standards Institute (ANSI) Electric Vehicles Standards Panel (EVSP) published of a Progress Report on activity within the standardization community to address the gaps and recommendations described in the ANSI EVSP’s Standardization Roadmap for Electric Vehicles – Version 2.0 (May 2013). (Earlier post.)
Available as a free download, the report outlines significant developments including new areas where there is a perceived need for additional standardization work to facilitate the safe, mass deployment of plug-in electric vehicles (PEVs) and charging infrastructure in the United States.
Calls for an international 48V electrical standard for vehicles; looming WLTP implementation
December 01, 2014
At the 2nd International Conference Automotive 48 V Power Supply Systems, held last week in Düsseldorf, Germany, Controlled Power Technologies (CPT), a major sponsor of the event, together with leading car makers and Tier 1 suppliers, argued the need for an internationally agreed 48V electrical standard. Such a standard will be necessary for the global automotive industry to achieve the economies of scale demanded by original equipment manufacturers.
CPT, together with other sponsors of the event, including AVL and Ricardo, is in the vanguard of 48V mild hybrid developments intended to address the ever-tightening European CO2 regulations and potentially a new and more aggressive test cycle—i.e., the Worldwide harmonized Light vehicles Test Procedures (WLTP).
Ongoing market rollout for SAE hydrogen fueling standards
November 10, 2014
At the Fuel Cell Seminar and Energy Exposition (FCS&EE) today in Los Angeles (co-sponsored by the US Department of Energy (DOE), Toyota and Honda, among others), SAE is providing a short course on “SAE H2 Fueling Standardization”; the course is presented by Jesse Schneider from BMW and Steve Mathison from Honda, both of whom have been deeply involved in the development of the SAE hydrogen fueling standards. (Earlier post.) The event is the most recent example of a concerted effort to educate stakeholders and encourage the implementation of the SAE hydrogen fueling standards.
Validated in the lab and proven in the field over the last decade, these standards provide the basis for hydrogen fueling for the first generation of infrastructure worldwide. There are currently four SAE standards in this area: the geometry of the fueling nozzle-receptacle interface (SAE J2600); hydrogen fuel quality (SAE J2719); FCEV to hydrogen station communication (SAE J2799); and hydrogen fueling (SAE J2601).
EPRI, 8 automakers and 15 utilities to create an open grid integration platform for plug-in electric vehicles
July 29, 2014
The Electric Power Research Institute, 8 automakers and 15 utilities are working to develop and to demonstrate an open platform that would integrate plug-in electric vehicles (PEVs) with smart grid technologies enabling utilities to support PEV charging regardless of location. The open platform will simplify and streamline V2G (vehicle-to-grid) communications, enabling PEVs to provide grid services and increasing the overall value proposition of plug-in vehicles.
The goal of this program is to develop a cloud-based, central server that would receive grid requests from a utility—such as Demand Response—and then translate and standardize that request so it could be relayed to all appropriate plug-in vehicles in the designated area. Automakers would be expected to develop and deploy technologies compatible with these smart grid communications.
SAE publishes SAE J2601 standard to harmonize H2 fueling of Fuel Cell Electric Vehicles worldwide

SAE has published the J2601 standard, “Fueling Protocols for Light Duty Gaseous Hydrogen Surface Vehicles”, the light duty hydrogen fueling protocol which will serve as a baseline for the first generation of infrastructure for refueling Fuel Cell Electric Vehicle (FCEVs). (Earlier post.)
This standard will be used to harmonize the protocol for hydrogen fueling stations worldwide for both 35 MPa and 70 MPa. Obtaining extended driving ranges with hydrogen fueling is accomplished by compressing hydrogen to 70 MPa (or H70).
Federal Highway Administration to award up to $2M for assistance in setting up certification environment for connected vehicles
June 28, 2014
The US Department of Transportation’s (DOT) Federal Highway Administration (FHWA) has issued a request for applications (RFA DTFH6114RA00014) for assistance in establishing a future certification environment for connected vehicle devices and applications. Estimated funding is up to $2 million.
DOT currently is assessing applications that realize the full potential of connected vehicles, travelers and infrastructure both to enhance current operational practices and to transform future surface transportation systems. To realize this potential, connected vehicle equipment and applications must meet minimum performance requirements, conform to common technical standards, and interoperate with one another. Certification testing provides a formal means of verifying that a device, application or service meets these requirements. DOT is seeking a partner to work in a cooperative agreement to:
SAE taskforce completes two technical standards on hydrogen refueling; harmonizing the global infrastructure
March 24, 2014
To support the impending roll-out of hydrogen fueling infrastructure and Fuel Cell Electric Vehicles (FCEV), SAE International’s Fuel Cell Standards Taskforce has completed two technical standards: SAE J2601, “Fueling Protocols for Light Duty Gaseous Hydrogen Surface Vehicles”; and SAE J2799, “Hydrogen Surface Vehicle to Station Hardware and Software”. The standards have been created to harmonize hydrogen fueling worldwide for both 35 MPa and 70 MPa pressures.
J2601. SAE J2601 (also with J2799) fuels fuel cell vehicle hydrogen storage systems quickly to a high state of charge (SOC) without violating the storage system operating limits, explained Jesse Schneider, Sponsor of both Standards SAE J2601 & J2799, in a presentation at the SAE 2014 Hybrid & Electric Vehicle Technologies Symposium earlier this year. SAE J2601 defines parameters for a hydrogen fueling experience similar to conventional fueling and is considered one of the key standards required for the commercialization of fuel cell vehicles and hydrogen stations.
