Juri Sudheimer Discusses MANNOL's Development of Fluids for Electric Vehicles
The rise of electric vehicles (EVs) is transforming the automotive landscape, necessitating new lubricant requirements. Juri Sudheimer, founder of MANNOL, highlights that operating fluids are now essential to the system architecture of EVs, managing friction, heat dissipation, and component protection simultaneously. This shift demands specialized solutions tailored to specific configurations and electrical loads, moving away from the concept of a universal oil. As EVs and hybrids integrate power electronics with traditional mechanical systems, the need for advanced lubricants becomes critical. Sudheimer notes that the evolution of e-transmission fluids presents unique challenges, including fluid degradation that affects electrical properties and increases noise and vibration (NVH). This complexity requires a new testing philosophy focused on electrical stability and material compatibility, alongside traditional anti-wear performance. Looking ahead, the automotive industry must adapt to these evolving lubricant needs as electrification continues to reshape market dynamics. No further timeline was disclosed at the time of publication.

Why Electric Vehicle NVH Testing Demands a Different Approach than ICE Validation
In a recent development within the automotive industry, transmission engineers have encountered unexpected challenges when testing new electric vehicle (EV) drivetrains on test benches originally designed for internal combustion engine (ICE) components. During these tests, while the data appears to be accurate, engineers have noted an unusual high-pitched whine at 3,200 rpm, indicating a harmonic issue not accounted for in initial simulations. This phenomenon raises concerns about the compatibility of existing testing equipment with the unique characteristics of EV drivetrains. The findings highlight the need for updated testing protocols and equipment that can adequately address the distinct sound signatures and performance metrics of electric vehicles. As the industry shifts towards electrification, understanding and resolving these discrepancies will be crucial for ensuring the reliability and efficiency of EV technology.
