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.
SAE task force agrees on frequency of operation and power classes for wireless power transfer for light-duty plug-in vehicles
November 15, 2013
SAE International J2954 Task Force for Wireless Power Transfer (WPT) of Light Duty, Electric and Plug-in Electric Vehicles, has agreed upon two key factors for the Technical Information Report (TIR) on interoperability for the first phase of pre-commercial development: a common frequency of operation (85 kHz) and the definition of three power classes for light duty vehicles: WPT 1, 2 and 3.
Made up of OEMs, WPT Suppliers, industry experts and government representatives, the Task Force plans to complete the TIR in early 2014. The SAE Technical Information Report will be followed by publication of SAE J2954 Standard, based on field data confirmation.
ANSI releases version 2 of EV Standardization Roadmap
May 14, 2013
The document tracks progress to implement recommendations made in the roadmap version 1.0, released in April 2012 (earlier post), and identifies additional areas where there is a perceived need for standardization work to help facilitate the safe, mass deployment of electric vehicles and charging infrastructure in the United States.
ACEEE report recommends steps toward international alignment of heavy-duty vehicle efficiency standards
April 05, 2013
A new report published by the American Council for an Energy-Efficient Economy (ACEEE) recommends the international harmonization of fuel efficiency and/or greenhouse gas emissions standards for heavy-duty trucks and buses.
Foundational steps toward such alignment would include a common set of test cycles and test payload weights, which would serve to define universal measures of vehicle performance. This in turn would permit a standardized calculation of cost-effectiveness of technology improvements as a function of regional conditions. This would also allow comparison of vehicles in a range of driving conditions, and in particular would allow buyers to estimate performance over their own duty cycles, the report suggests.
