Electric vehicle components are subject to frequent use and mechanical stress, which can affect their durability and performance over time. Charging port doors, in particular, must withstand repeated opening and closing cycles while maintaining reliability.
This article focuses on the role of rotary dampers in charging port mechanisms. For a complete overview of charging port applications, read our article on charging port dampers.

The importance of controlled motion
Abrupt movements and repeated shocks can damage charging port doors and compromise their functionality.
Rotary dampers provide controlled deceleration, reducing impact forces and protecting components from wear and breakage.
How rotary dampers work
The viscous fluid inside the damper absorbs and dissipates the energy generated during movement, ensuring smooth and controlled operation without affecting the design or dimensions of the component.
