Car accidents reveal the challenges of component reliability

Recently, a domestic new energy vehicle startup issued two accountability notices regarding quality incidents, once again drawing attention to the reliability of automotive components.

As automobiles transition towards intelligent electrification, the complexity and integration of components increase significantly. A reliability defect in even the smallest part can trigger a chain reaction, ranging from affecting the user experience to threatening driving safety.In this context, establishing a rigorous component reliability testing system has become crucial for automakers to ensure product quality.

The impact of environmental test chambers on the automotive industry

As complex industrial products, automobiles comprise an exceptionally large number of components. Statistics show that the average car consists of approximately 10,000 to 20,000 parts. These components span multiple fields including mechanical, electronic, hydraulic, and polymer materials, collectively forming the vehicle's operational system.

Throughout the entire vehicle lifecycle, components must endure demanding environmental challenges: extreme temperature fluctuations from deep cold to intense heat; corrosive damp conditions to dry brittleness; persistent vibration-induced fatigue loading; along with factors such as UV radiation, particulate matter (dust), and chemical agents that accelerate performance degradation.
