Lubrizol's EVOGEN™ driveline e-fluid technologies are custom-designed to precisely meet the requirements of OEM electric drivetrains.
These advanced fluids cater to both dry and wet motor configurations in passenger and commercial vehicles, empowering users to optimize their designs for enhanced efficiency and performance.
The growth of all types of electrified vehicles—from mild hybrid through to full hybrid, battery electric and fuel cell—is leading to increasingly diverse vehicle drivelines in the market. Each vehicle design requires fluids to lubricate and cool hardware. And the fluid requirements differ depending on the specific hardware design.
In a battery electric vehicle, the vehicle is powered solely by an electric motor. The combination of the electric motor, inverter and reduction gears is termed “e-axle.” Some deploy a “dry e-motor” arrangement, where a water-based fluid indirectly provides the e-motor cooling, and a separate lubricant protects the gears. In a wet e-motor arrangement, the fluid directly cools and protects both the motor and gear reduction unit. There is a trend towards wet e-motor arrangements, which allow OEMs to design more compact and more efficient hardware.
This presentation describes an all-in-one e-fluid technology to cool inverter, e-motor and provide EV gear lubrication.
