Electric Vehicle Acceleration, Gradeability, and Deceleration Test Procedure

1993-05-01
HISTORICAL
J1666_199305
This SAE Recommended Practice establishes uniform procedures for testing electric battery-powered vehicles which are capable of being operated on public and private roads. It is the intent of this document to provide standard tests which will allow various performance characteristics of electric vehicles to be cross-compared on a common basis in specifications, technical papers, and engineering discussions. The tests concern attributes of the total vehicle system rather than those of its subsystems and components. Tests of components such as batteries are the subject of separate procedures. The road tests specified in this document are recommended for use whenever possible particularly to establish vehicle performance specifications. The dynamometer procedures are included primarily to facilitate development testing. Paragraph 2.2 provides definitions of terminology used in this document.

SAE Cold Start and Driveability Procedure

1998-08-01
HISTORICAL
J1635_199808
To subjectively evaluate engine starting behavior and driveability characteristics of a motor vehicle which has been soaked at ambient temperature for a given time period after attaining a stabilized engine coolant temperature. This SAE Recommended Practice also defines driveability defects and the rating system. This evaluation may be affected by ambient temperature, altitude, fuel, and the road system. The vehicle should be evaluated with all fuels recommended by the manufacturer. A partial list comprises reformulated gasoline, ethanol/gasoline and methanol/gasoline blends of various proportions, diesel #1, and diesel #2.

Fuel Economy Measurement--Road Test Procedure--Cold Start and Warm-Up Fuel Economy

1979-05-01
HISTORICAL
J1256_197905
This procedure is a modification of the urban driving cycles noted in SAE J1082 and which is run on a suitable road or test track. The procedure yields cold start/warm-up fuel economy values indicative of consumer level at the ambient condition of the test. Within referenced limitations, the procedure can be utilized to determine the fuel economy differential among vehicles or between vehicle changes. Purpose This SAE Recommended Practice provides a uniform test procedure for measuring the fuel economy of light-duty vehicles during cold start and warm-up operation (motor vehicles designed primarily for transportation of persons or property and rated at 4500 kg GVW (10 000 lb) or less) on suitable roads.
