Electric Vehicles and NVH - Less is….more?

In Electric Vehicles (EVs), minimizing Noise, Vibration, and Harshness (NVH) is crucial as the absence of an internal combustion engine makes other noises more prominent and perceptible to passengers. Damping greases play a significant role in reducing NVH levels in several components of EVs.

1. Electric Motor Bearings:

• Application: Damping greases are used in the bearings of electric motors to reduce noise and vibration, ensuring smooth and quiet operation of the motor.
• Benefit: Provides smoother driver and passenger experience by minimizing the operational noises typical to electric motors.

2. Gearboxes and Transmissions:

• Application: Damping greases in gearboxes and transmission components help in reducing noise and vibration during power transfer and gear shifts.
• Benefit: Contributes to the overall reduction of drivetrain noise, which is particularly noticeable in the quiet cabin environment of an EV.

3. Switches and Controls:

• Application: In buttons, switches, and rotary controls, damping greases provide a refined, premium feel, reducing mechanical noise and enhancing user interaction with vehicle controls.
• Benefit: Enhances user interface experience by delivering quality tactile feedback and reducing audible clicks and movement noise.

4. Door Locks and Latches:

• Application: Damping greases applied to door locks, latches, and hinges prevent squeaking and ensure smooth operation.
• Benefit: Ensures the quiet and smooth operation of doors, contributing to overall cabin comfort and user satisfaction.

5. Cabin Adjustment Mechanisms:

• Application: Used in seat adjusters, ventilation louvers, and other adjustment mechanisms inside the cabin to enable smooth, noise-free operation.
• Benefit: Improves the perceived quality of interior components and enhances passenger comfort.

6. Connector Plugs:

• Application: In EVs, damping greases can be used on connector plugs to ensure smooth insertion and removal while protecting against wear and corrosion.
• Benefit: Ensures longevity and reliable performance of electrical connections in EVs.
