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.
