Customized Special Lubricants for The Automotive Manufacturing Industry

Customer Requirements: 

A certain automobile manufacturing enterprise is committed to building high-performance electric vehicles, and its power system adopts a new type of high-speed motor and advanced battery thermal management system. During operation, the motor bearings face wear problems caused by high temperature and high speed, and conventional lubricants cannot meet their long-term stable operation requirements. At the same time, the coolant in the battery thermal management system needs to have efficient heat dissipation performance, good electrical insulation, and compatibility with system materials to ensure that the battery can maintain the optimal working temperature under various working conditions, ensuring battery life and vehicle range.

Customized Solution: 

In response to the lubrication problem of motor bearings, our R&D team has selected high-performance perfluoropolyether base oil, combined with a specially formulated nanoscale molybdenum disulfide additive. Perfluoropolyether base oil has excellent high-temperature stability and low volatility, and can form a stable lubricating film in high-temperature and high-speed environments; Nano molybdenum disulfide additive further enhances lubrication performance, effectively reduces friction coefficient, and minimizes wear. For battery thermal management coolant, deionized water is used as the basis, and self-developed polymer heat dissipation additives and special corrosion inhibitors are added. Polymer heat dissipation additives greatly improve the heat dissipation efficiency of the coolant, while special corrosion inhibitors prevent the coolant from corroding the metal components in the system, while ensuring that the coolant has good electrical insulation and meets the safety requirements of the battery system.

Implementation Effect: 

After the customized special lubricant was applied to the automotive power system, the wear rate of the motor bearings was reduced by 70%. After 1000 hours of continuous high-speed operation, the performance of the bearings remained stable, effectively extending the maintenance cycle and service life of the motor. The battery thermal management coolant ensures that the temperature fluctuation of the battery is controlled within a very small range under extreme working conditions (such as high temperature fast charging and low temperature driving), and the battery range is increased by 8% under comprehensive working conditions. The battery cycle life is also increased by 15%, significantly improving the overall performance and reliability of electric vehicles, helping customers' products stand out in the market, and winning wide recognition in the high-end electric vehicle market.
