Abstract
- The electric vehicle technology is vacillating at remarkable rates. Thus, the enhancements of the associated fluids and their associated additives are also changing. Varying conditions, depending on the EV system and usage albeit passenger car or heavy duty, can cause the formation of conductive deposits and corrosion within drivetrains. Corrosion is a wellknown entity and tools to evaluate under these conditions are imperative. However, the formation of conducting layer deposits, a corrosion product, has also been identified as a failure mechanism for current electric motor designs. Different drivetrain base stocks along with additive formulations may have inherently different corrosion rates producing conducting layer deposits in both solution and vapor phases. To help resolve these issues, a group of industry experts involving both OEM's and lubricant experts from across the globe, have developed bench tests to better predict these conductive and corrosion deposits. The apparatus' developed are the conductive deposit test and the wire corrosion test. This paper covers several different aspects of the EV drivetrains and fluids performing in the CDT and WCT that show both field correlation and repeatability. [ABSTRACT FROM AUTHOR]
