This SAE Information Report details the important new performance properties and suggested test methods for lubricants used in e-Mobility drivetrain components. The lubricants under discussion are those used in electrified drivetrains, mainly electric-transmissions and axles (e-transmissions and e-axles). The scope is limited to those geared systems in which an electric motor (e-motor) is immersed in the powertrain lubricant or comes in contact with the powertrain lubricant. Though the report focuses on new lubricant attributes, some information on conventional lubricant attributes is included. The information presented here will be helpful in understanding the similarities and differences between conventional (i.e., internal combustion engine (ICE)) and e-Mobility powertrain systems.
Rationale
Automotive manufacturers are turning to electrification to meet new regulatory requirements and consumer expectations to reduce greenhouse gases, in particular carbon dioxide. Electric-Mobility (e-Mobility) is becoming a larger and more prominent part of the transportation industry and by 2030 the majority of light vehicles will include some form of electrification. E-Mobility encompasses powertrain technologies that include hybrid electric vehicles (HEV), plug-in hybrid electric vehicles (PHEV), battery electric vehicles (BEV), and fuel cell electric vehicles (FCEV). In many of these powertrains, the lubricant is in contact with the electric motor (e-motor), and this architecture is anticipated to continue. While the first e-Mobility vehicles were designed around current lubricants, these technologies are evolving rapidly, and newer designs require new lubricant performance attributes. This information report provides lubricant guidance for electrical and mechanical component designers, component and/or vehicle manufacturers, and users of e-Mobility powertrains. The information will also be useful for lubricant formulators, fluid manufacturers, and marketers who supply fluid for e-Mobility drivetrain components. This area is evolving rapidly, and this report will be revised accordingly.
The Driveline and Chassis Lubrication Technical Committee is responsible for development of SAE Standards, Recommended Practices, Information Reports and related information pertinent to the classification, performance characteristics, physical properties and test requirements for: lubricants designed for the use in axles, differentials, power dividers, transmissions, and hydraulic components used in automotive-type vehicles and their associated equipment ; selection of greases and maintenance of parts by the standardization of terms and grease lubricated parts of automotive equipment , procedures and specifications of hydraulic fluids used in automatic shift transmissions, wet brake systems and hydraulic systems. The Fuel and Lubricants Steering Committee has been formed under the committee's direction. Participants in the SAE Driveline and Chassis Lubrication Technical Committee include OEMs, suppliers, consulting firms, government and other interested parties.
* Redlines comparisons are available for those standards
listed in the Revision History that contain a radio button. A
redline comparison of the current version against a revision is
accomplished by selecting the radio button next to the standard and
then selecting 'compare'. At this time, Redline versions only exist
for some AMS standards. SAE will continue to add redline versioning
with ongoing updates to SAE MOBILUS.

Search Tips: Search Operators:AND, OR, NOT; Wild Cards; Using Quotes
SAE MOBILUS® Search Tips
Please note: All terms not contained within quotes, will be evaluated using the OR operator. This means that your search results will contain all results that contain ANY of the entered terms.
AND, OR, NOT
SAE MOBILUS supports the use of the AND, OR and NOT BOOLEAN operators ONLY function with the Advanced Search.
Wild Cards
Using the asterisk, ( * ) allows you to search for a partial word. For example, entering a keyword search of aero* will search for any word beginning with aero.
Using the question mark, ( ? ) allows you to search for a word with a single character wildcard. For example, searching for t?re would match both tire and tyre
Using Quotes
Words in double quotes " " are treated as a phrase. Conducting a search for "heat model" will return all results in which the exact phrase "heat model" is found, while "heat modeling" would NOT be included.
A term combined with a phrase will be joined with an OR operator.
Searching for Standards
When searching for a standard please use the entire Document Number assigned, which includes the abbreviation. A space can be used, or omitted between the abbreviation and number.
