The lifespan of forgings for new energy vehicles

The lifespan of forgings for new energy vehicles is an important factor affecting vehicle safety and economy. This article discusses the lifespan of forgings for new energy vehicles from the perspectives of national policies and actual production, with specific examples.

From the perspective of national policies, the Chinese government has established regulations on the lifespan of forgings for new energy vehicles. For example, GB/T 32237-2015 “Forged Aluminum Alloy Parts for New Energy Vehicles” clearly specifies the methods for mechanical performance testing, hydrogen embrittlement test, stress corrosion test, magnetic particle inspection, and peeling test. In addition, China has also issued multiple national standards related to the quality evaluation and certification of new energy vehicle components, such as “General Technical Conditions for New Energy Vehicle Electrical Control Systems, New Energy Vehicle Aluminum Alloy Body Structural Components, and New Energy Vehicle Lithium Iron Phosphate Power Batteries and Other Parts” (GB/T 38039.1-2020). These standards directly or indirectly affect the lifespan of forgings for new energy vehicles.

In actual production, the lifespan of forgings for new energy vehicles is affected by multiple factors, such as manufacturing processes, material quality, environmental conditions, and maintenance. Different materials and manufacturing processes have different effects on the lifespan of forgings. For example, aluminum alloy forgings have better performance in density and corrosion resistance compared to steel forgings but have poor wear resistance and tensile strength. Titanium alloy forgings have advantages such as low density, high strength, and good corrosion resistance, but they are relatively expensive. In order to improve the durability and reliability of forgings for new energy vehicles, it is necessary to pay attention to material selection and manufacturing process optimization in actual production.

Overall, the lifespan of forgings for new energy vehicles is determined by multiple factors and requires policy support and continuous innovation and improvement in actual production. Only by doing so can we truly improve the lifespan of forgings for new energy vehicles, ensuring vehicle safety and economy.
