Electric Drive Battery Pack System Functional Guidelines

Electric Vehicle Forum Committee
  • Ground Vehicle Standard
  • J2289_200011
  • Historical
Published 2000-11-15 by SAE International in United States
This SAE Information Report describes common practices for design of battery systems for vehicles that utilize a rechargeable battery to provide or recover all or some traction energy for an electric drive system. It includes product description, physical requirements, electrical requirements, environmental requirements, safety requirements, storage and shipment characteristics, and labeling requirements. It also covers termination, retention, venting system, thermal management, and other features. This document does describe guidelines in proper packaging of the battery to meet the crash performance criteria detailed in SAE J1766. Also described are the normal and abnormal conditions that may be encountered in operation of a battery pack system --Purpose This document provides the guidelines for designing a battery system to package into manufacturerÕs electric drive vehicles. It lays the foundation for electric vehicle battery systems and provides information to assist in developing a robust battery system. --Field of Application This document applies to vehicles using electrically rechargeable storage traction batteries that provides energy and power to an electric drive system for propulsion, namely Electric Vehicles and some Hybrid Electric…

Vibration Testing of Electric Vehicle Batteries

Electric Vehicle Forum Committee
  • Ground Vehicle Standard
  • J2380_199801
  • Historical
Published 1998-01-01 by SAE International in United States
This SAE Recommended Practice describes the vibration durability testing of a single battery (test unit) consisting of either an electric vehicle battery module or an electric vehicle battery pack. For statistical purposes, multiple samples would normally be subjected to such testing. Additionally, some test units may be subjected to life cycle testing (either after or during vibration testing) to determine the effects of vibration on battery life. Such life testing is not described in this procedure; SAE J2288 may be used for this purpose as applicable.

Measurement of Hydrogen Gas Emission From Battery-Powered Passenger Cars and Light Trucks During Battery Charging

Electric Vehicle Forum Committee
  • Ground Vehicle Standard
  • J1718_199704
  • Historical
Published 1997-04-01 by SAE International in United States
This SAE Recommended Practice describes a procedure for measuring gaseous hydrogen emissions from the aqueous battery system of a battery-powered passenger car or light truck. The purpose of this procedure is to determine what concentrations of hydrogen gas an electric vehicle together with its charger will generate while being charged in a residential garage. Gaseous emissions are measured during a sequence of vehicle tests and laboratory tests that simulate normal and abnormal conditions during operational use. The results of this test may be used to determine whether or not forced air ventilation is required when a particular electric vehicle and its associated battery and charging system are used in a residential garage.

Energy Transfer System for Electric Vehicles--Part 1: Functional Requirements and System Architectures

Electric Vehicle Forum Committee
  • Ground Vehicle Standard
  • J2293/1_199703
  • Historical
Published 1997-03-01 by SAE International in United States
SAE J2293 establishes requirements for Electric Vehicles (EV) and the off- board Electric Vehicle Supply Equipment (EVSE) used to transfer electrical energy to an EV from an Electric Utility Power System (Utility) in North America. This document defines, either directly or by reference, all characteristics of the total EV Energy Transfer System (EV-ETS) necessary to insure the functional interoperability of an EV and EVSE of the same physical system architecture. The ETS, regardless of architecture, is responsible for the conversion of AC electrical energy into DC electrical energy that can be used to charge the Storage Battery of an EV, as shown.

Recommended Practice for Performance Rating of Electric Vehicle Battery Modules

Electric Vehicle Forum Committee
  • Ground Vehicle Standard
  • J1798_199701
  • Historical
Published 1997-01-01 by SAE International in United States
This SAE Recommended Practice provides for common test and verification methods to determine Electric Vehicle battery module performance. The document creates the necessary performance standards to determine (a) what the basic performance of EV battery modules is; and (b) whether battery modules meet minimum performance specification established by vehicle manufacturers or other purchasers. Specific values for these minimum performance specifications are not a part of this document.

Recommended Practice for Packaging of Electric Vehicle Battery Modules

Electric Vehicle Forum Committee
  • Ground Vehicle Standard
  • J1797_199701
  • Historical
Published 1997-01-01 by SAE International in United States
This SAE Recommended Practice provides for common battery designs through the description of dimensions, termination, retention, venting system, and other features required in an electric vehicle application. The document does not provide for performance standards. Performance will be addressed by SAE J1798. This document does provide for guidelines in proper packaging of battery modules to meet performance criteria detailed in J1766.

Life Cycle Testing of Electric Vehicle Battery Modules

Electric Vehicle Forum Committee
  • Ground Vehicle Standard
  • J2288_199701
  • Historical
Published 1997-01-01 by SAE International in United States
This SAE Recommended Practice defines a standardized test method to determine the expected service life, in cycles, of electric vehicle battery modules. It is based on a set of nominal or baseline operating conditions in order to characterize the expected degradation in electrical performance as a function of life and to identify relevant failure mechanisms where possible. Accelerated aging is not included in the scope of this procedure, although the time compression resulting from continuous testing may unintentionally accelerate battery degradation unless test conditions are carefully controlled. The process used to define a test matrix of accelerated aging conditions based on failure mechanisms, and to establish statistical confidence levels for the results, is considered beyond the scope of this document. Because the intent is to use standard testing conditions whenever possible, results from the evaluation of different technologies should be comparable. End-of-life is determined based on module capacity and power ratings. This may result in a measured cycle life different than that which would be determined based on actual capacity; however, this approach permits a…

SAE Electric Vehicle Conductive Charge Coupler

Electric Vehicle Forum Committee
  • Ground Vehicle Standard
  • J1772_199610
  • Historical
Published 1996-10-01 by SAE International in United States
This SAE Recommended Practice covers the general physical, electrical, and performance requirements for the electric vehicle conductive charging system and coupler for use in North America. The intent of the document is to define a common electric vehicle conductive charging system architecture and the functional requirements of the vehicle inlet and mating connector. Application and compatability requirements for the connector and vehicle inlet are state herein.
