Electric vehicles (EVs) have unique tribological performance requirements compared to internal combustion engine vehicles, necessitating the research of lubricants to improve performance and efficiency. Lubricants play a crucial role in electrical compatibility, thermal management, and material adaptability as e-mobility technologies evolve. The electrical characteristics of a lubricant can be optimized to reduce bearing electrical damage, which is common in EVs. Thermal qualities, such as thermal conductivity, heat capacity, and flow rate, influence the thermal efficiency of an electrical motor. Key issues for EVs include lubricant's thermal and electrical qualities, copper corrosion, and compatibility with EV elastomers/polymers. seals, bearings, and gears must be adequately greased at speeds exceeding 25,000 rpm to avoid friction and wear. New lubricants will be needed for batteries and motors, as they come into contact with motors and batteries. Copper is used for most components due to its excellent electrical conductivity, making copper compatibility critical. Lubricants must have stable dielectric properties to withstand high speeds, high temperatures, increased oxidation, particle abrasion, and fluctuating electric and magnetic fields. They must also have increased electrical insulation to prevent arcing and prevent component breakage, swelling, and cracking. specific designed lubricants are required to avoid component damage and early failure due to incorrect lubrication in a highly fluctuating charged environment.
