| description abstract | The development of electric vehicle (EV) technology has evolved rapidly over the past few decades, with significant improvements in performance and efficiency. Among the most vital yet often overlooked aspects of EVs are the lubricants and materials used in their powertrains/drivelines. The role of lubricants and materials in EVs is multifaceted, as they directly impact component life, vehicle efficiency, energy conservation, and the overall driving experience. Despite advancements, challenges remain, especially in the field of lubrication under harsh thermal and electrical conditions. This special issue contains 15 papers disseminating some of the most recent advancements in the key areas of EV lubricants, testing, advancements, and the unique demands these vehicles place on lubrication technologies. Although each of the papers has its own merits, together they emphasize the need for a better understanding of tribo-electric contacts, lubricants, and materials that can adapt to the changing wear mechanisms, offering protection across a range of operational conditions. As the performance demands of electric motors and drivetrains continue to evolve, lubricant technology must also advance to meet these needs. | |
