Targeting eAxle efficiency through additives
Highly linear synthetic fluids with uniform molecular weight and polymer chains with limited branching can deliver impressive cooling, traction and efficiency benefits. However, their use introduces additional lubrication challenges because linear synthetics form particularly thin tribofilms. Additives can unlock the full efficiency benefits of these advanced fluids for OEMs, but they must be applied with understanding and skill.
This article explores that extending Electric Vehicle (EV) range by focusing on fluid viscosity alone can lead to dead ends where efficiency is not improved and durability is compromised. Customized additive support for specific combinations of fluid and OEM hardware design is the most direct route to optimized efficiency.
