Abstract:
As the automobile market shifts to electric vehicles (EVs), the demand for proper lubrication is expanding exponentially. Selecting a lubricant for specific qualifications such as noise, efficiency, and compatibility with electrical currents and electromagnetic fields is an ongoing challenge for EVs. Appropriate lubrication is integral to the longevity and sustainability of electric vehicles. Determining characteristics such as corrosion resistance, high temperature operation, consistency, and stiffness are paramount in the classification of a grease to a type and provide valuable insight into potential applications. By using modified test methods such as the determination of corrosion preventive properties (ASTM D6138), as well as dropping point (ASTM D2265) and penetration (ASTM D217) determination, these characteristics can be obtained and interpreted. Replicating conditions that may be experienced in operation, these tests provide additional behavioral information used in the classification of a grease. Without these characteristics and behavioral information, EV noise, efficiency, and productivity of sensors may be less than optimal. This poster highlights testing instrumentation from Koehler Instrument Company to test for the aforementioned test methods.
