Lubricants applicable for electrical vehicles ?
Electric vehicles (EVs) use a variety of lubricants to keep their systems running smoothly and efficiently. Some of the lubricants commonly used in EVs include:
Gear oils: EVs use gearboxes in their drivetrains to transfer power from the electric motor to the wheels. Gear oils are used to lubricate these gearboxes and help to reduce friction and wear.
Grease: Grease is used in EVs to lubricate joints and other components that are exposed to high loads and/or high speeds.
Thermal oils: EV batteries and power electronics generate heat during operation, thermal oils are used to transfer this heat from the battery and power electronics to a heat exchanger, where it is dissipated.
Coolants: Electric motors and power electronics generate heat during operation, and coolants are used to dissipate this heat and keep the system from overheating.
It’s important to note that EV lubricants must meet specific requirements such as high thermal stability, high viscosity index, and low volatility to ensure their performance in the high-temperature and high-speed operating conditions of the electric drivetrain.
It is also important to note that not all lubricants are suitable for use in electric vehicles, and it is crucial to use lubricants that are specifically designed and approved for use in EVs to ensure they meet the unique requirements of these systems and to prevent damage to the vehicle’s components.
