Liquid Leak Tightness Evaluation Methodology for EV Battery Packs Informational Report

2024-04-23
CURRENT
J3277_202404
This technical information report (IR) presents a methodology to evaluate battery pack liquid leak tightness attributes to be used in a production line to satisfy the functional requirement for IPX7, water ingress requirement, and no sustainable coolant leakage for coolant circuits. The Equivalent Channel Method is used as a suggested production leak tightness requirement for a given battery pack design that will correlate and assure that the battery pack meets or exceeds its functional requirement. Obtaining the specific geometry of the Equivalent Channel (EC) for a given battery pack is done analytically and empirically in consideration of the product design limitations. This document is a precursor to J3277-1, which will present the practices to qualify that product leak tightness is equal or better than the maximum allowed EC for that product using applicable and commercially available leak test technologies.

Automotive Battery Recycling Identification and Cross Contamination Prevention

2024-03-25
WIP
J3071
This SAE Battery Identification and Cross Contamination Prevention document is intended to provide information that may be applicable to all types of Rechargeable Energy Storage System (RESS) devices. It is important to develop a system that can facilitate sorting by chemistry. The recycler is interested in the chemistry of the RESS. This is true for the recyclers of Lead Acid, Lithium Ion, Nickel Cadmium etc. Thus recyclers of RESS will receive RESS from automotive, commercial, and industrial applications. These RESS have the potential to be contaminated with a RESS of an incompatible chemistry. It is recognized that mitigation methods to reduce or eliminate the introduction of incompatible chemistries into a given recycling stream would also benefit safety and the environment.

Recommended Practice for Measuring Fuel Consumption and Range of Fuel Cell and Hybrid Fuel Cell Vehicles Fueled by Compressed Gaseous Hydrogen

2024-02-06
CURRENT
J2572_202402
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.

CURRENT
J537_202309
This SAE Standard serves as a guide for testing procedures of automotive 12 V storage batteries. The information contained herein was originally developed based on traditional ICE operation but can be more broadly applicable to other vehicle architectures. Although the test procedures contained herein are written from the standpoint of a 12 V nominal battery, they can be scaled for batteries with different nominal voltages.

Use Cases for Communication Between Plug-in Vehicles and Off-Board DC Charger

2023-08-31
CURRENT
J2836/2_202308
This SAE Information Report, SAE J2836-2, establishes use cases and general information for communication between plug-in electric vehicles (PEVs) and the DC off-board charger. Where relevant, this document notes, but does not formally specify, interactions between the vehicle and vehicle operator. This applies to the off-board DC charger for conductive charging, which supplies DC current to the vehicle battery of the electric vehicle through a SAE J1772 hybrid coupler or SAE J1772 AC Level 2-type coupler on DC power lines, using the AC power lines or the pilot line for power line communication (PLC), or dedicated communication lines that are further described in SAE J2847-2. The specification supports DC energy transfer via forward power flow (FPF) from grid-to-vehicle. The relationship of this document to the others that address PEV communications is further explained in Section 5.

Hydrogen Surface Vehicle to Station Communications Hardware and Software

2023-08-03
WIP
J2799
This standard specifies the communications hardware and software requirements for fueling hydrogen surface vehicles (HSV), such as fuel cell vehicles, but may also be used where appropriate, with heavy-duty vehicles (e.g., busses) and industrial trucks (e.g., forklifts) with compressed hydrogen storage. It contains a description of the communications hardware and communications protocol that may be used to refuel the HSV. The intent of this standard is to enable harmonized development and implementation of the hydrogen fueling interfaces.This standard is intended to be used in conjunction with the hydrogen fueling protocols in SAE J2601 and J2601/5, and nozzles and receptacles conforming with SAE J2600.

CURRENT
J2907_202308
This document was developed to provide a method of obtaining repeatable measurements that accurately reflects the performance of a propulsion electric drive subsystem, whose output is used in an electrified vehicle regardless of complexity or number of energy sources. The purpose is to provide a familiar and easy-to-understand performance rating. Whenever there is an opportunity for interpretation of the document, a good faith effort shall be made to obtain the typical in-service performance and characteristics and avoid finding the best possible performance under the best possible conditions. Intentional biasing of operating parameters or assembly tolerances to optimize performance for this test shall not be considered valid results in the scope of this document.

CURRENT
USCAR17-6
This document contains procedures for testing performance of SMB-style electrical terminals, connectors and components for coaxial cable connection systems intended for road vehicle applications. These are often called FAKRA II designs. This specification does not apply to the Non RF portion of a Hybrid RF connection system. The intent of this specification is to qualify sealed and unsealed RF connectors that operate at frequencies from DC to 6 GHz. The characteristic impedance of the SMB/FAKRA connection system is 50 ohms however this specification does not exclude the use of these RF connectors on non-50 ohm cables or systems. This specification does not apply to single conductor wire or twisted pair connection systems. This specification (along with SAE/USCAR 18) is designed to provide the mechanical and electrical data required to insure that assemblies from various manufacturers will perform reliably in actual conditions.

Potential Standard Steels

2023-06-06
CURRENT
J1081_202306
This SAE Information Report provides a uniform means of designating wrought steels during a period of usage prior to the time they meet the requirements for SAE standard steel designation. The numbers consist of the prefix PS1 followed by a sequential number starting with 1. A number once assigned is never assigned to any other composition. A PS number may be obtained for steel composition by submitting a written request to SAE Staff, indicating the chemical composition and other pertinent characteristics of the material. If the request is approved according to established procedures, SAE Staff will assign a PS number to the grade. This number will remain in effect until the grade meets the requirements for an SAE standard steel or the grade is discontinued according to established procedures. Table 1 is a listing of the chemical composition limits of potential standard steels which were considered active on the date of the last survey prior to the date of this report.
