Abstract:
Electric vehicle (EVs) adoption continues to rise as passenger, fleet, and commercial sectors increase EV usage. As the automotive industry shifts towards electrification, the integration of high-voltage mechanical systems introduces new lubrication challenges. Therefore, EV powertrain lubrication requirements differ from those of conventional internal combustion-engine powertrains. EV powertrain bearings must handle increased axial loads, higher rotational speeds, and specific electrical conductivity requirements. Depending on the application, EV-specific lubricants may need to perform under high-speed, high-load, and high-voltage conditions. Additional requirements include noise dampening, copper compatibility, cooling capability, and high-temperature stability. Lubricant analysis plays a crucial role in ensuring these lubricants meet new and traditional tribological standards. This poster explores the real-life challenges EV lubricants face and highlights solutions provided by lubricant analysis instrumentation. These sophisticated tools accelerate testing by automating ASTM and related procedures, enabling faster, more reliable, and repeatable analysis for improved lubricant research and development.
