J2572_200608

This SAE Recommended Practice establishes uniform procedures for testing fuel cell and hybrid fuel cell electric vehicles, excluding low speed vehicles, designed primarily for operation on the public streets, roads and highways. The procedure addresses those vehicles under test using compressed hydrogen gas supplied by an off-board source or stored and supplied as a compressed gas onboard. This practice provides standard tests that will allow for determination of fuel consumption and range based on the US Federal Emission Test Procedures, using the Urban Dynamometer Driving Schedule (UDDS) and the Highway Fuel Economy Driving Schedule (HFEDS). Chassis dynamometer test procedures are specified in this document to eliminate the test-to-test variations inherent with track testing, and to adhere to standard industry practice for fuel consumption and range testing.

J1766_201401

Electric, Fuel Cell and Hybrid vehicles may contain many types of high voltage systems. Adequate barriers between occupants and the high voltage systems are necessary to provide protection from potentially harmful electric current and materials within the high voltage system that can cause injury to occupants of the vehicle during and after a crash. This SAE Recommended Practice is applicable to Electric, Fuel Cell and Hybrid vehicle designs that are comprised of at least one vehicle propulsion voltage bus with a nominal operating voltage greater than 60 and less than 1,500 VDC, or greater than 30 and less than 1,000 VAC. This Recommended Practice addresses post-crash electrical safety, retention of electrical propulsion components and electrolyte spillage.

RECOMMENDED PRACTICE FOR ELECTRIC AND HYBRID ELECTRIC VEHICLE BATTERY SYSTEMS CRASH INTEGRITY TESTING

J1766_199602

Electric and Hybrid Electric Vehicles contain many types of battery systems. Adequate barriers between occupants and battery systems are necessary to provide protection from potentially harmful factors and materials within the battery system, which can cause injury to occupants of the vehicle during different crash scenarios. This SAE Recommended Practice is applicable to all Electric Vehicle and Hybrid Electric Vehicle battery designs including those in SAE J1797. The potentially harmful factors and materials include electrical isolation integrity, electrolyte spillage and liquid interactions, and retention of the battery system. Maintaining electrical isolation of the system is important to prevent hazardous shock of vehicle occupants. Electrolyte spillage and battery fluid interactions should be minimized to prevent chemical reactions and electrical conductance. The latter could lead to an electrical shock hazard.

Information Report on the Development of a Hydrogen Quality Guideline for Fuel Cell Vehicles

2005-11-10

HISTORICAL

J2719_200511

This Information Report provides interim background information and an interim specification of hydrogen fuel quality for commercial proton exchange membrane (PEM) fuel cell vehicles. This Report also provides background information on how this interim specification was developed by the Hydrogen Quality Task Force (HQTF) of the Interface Working Group (IWG) of the SAE Fuel Cell Standards Committee. The constituents and thresholds listed in table 1 are based on a survey of the industry, the published literature and reflects current and draft analytical test methods. Some of the allowable constituent levels are higher than desired because a published detection method is not available for the desired threshold. Some of the allowable constituent levels may be lower than desired due to incomplete evaluations and/or an attempt to minimize testing costs (such as including methane in total hydrocarbons).
