Do New Energy Vehicles Need Undercoating?

[McEvelyn]

New energy vehicles do need undercoating, as it serves as protection for the chassis. The chassis of new energy vehicles is largely similar to that of fuel-powered vehicles. Introduction to Undercoating: The technical term for automotive undercoating is "UNDERCOATING," a high-tech adhesive rubber asphalt coating. It is non-toxic, offers high coverage and adhesion, and can be sprayed on exposed parts of the vehicle such as the chassis, wheel hubs, fuel tank, lower body panels, and trunk. It quickly dries to form a strong, elastic protective layer. Functions of Undercoating: It prevents impacts from flying stones and gravel, protects against moisture, acid rain, and salt corrosion on the metal parts of the chassis, prevents rust and corrosion, and ensures driving safety for the owner.

I think it's quite necessary to apply underbody armor for new energy vehicles. Having driven a new energy car for over three years, I'm really concerned about that large battery under the chassis. Although manufacturers provide some protection, it's still scary when road stones hit it. Last year, a small stone hit my car's underbody in the suburbs - luckily I had applied armor beforehand, or the battery pack might have been damaged. Friends living by the sea need to be especially careful due to severe salt corrosion. Be sure to use high-temperature resistant materials during application, otherwise it could affect battery cooling. Although it costs about a thousand yuan, considering battery replacement could cost 70,000-80,000 yuan, this expense really shouldn't be saved.

Applying underbody armor to new energy vehicles is indeed something worth serious consideration. The batteries are all suspended underneath the car, and while they come with protective casings from the factory, who hasn't encountered rough roads during daily driving? Once when I was driving a friend's car on a mountain road, I clearly heard the sound of stones hitting the underbody. Having an armor layer for cushioning would have provided much more peace of mind. This is especially recommended in rainy southern regions, where acidic substances in rainwater can slowly corrode metal components—you'll notice the difference after two or three years during maintenance. It's important to choose materials with good elasticity, like polyurethane, and avoid cheaper asphalt-based options. Regularly checking the integrity of the armor layer is also crucial.

Applying underbody armor to new energy vehicles is quite practical. I've owned a pure electric car for five years and frequently drive on highways. The underbody armor has indeed protected against many scrapes. The original anti-rust coating is relatively thin, while a thick armor layer can cushion impacts and prevent rust corrosion. During installation, be careful to avoid ventilation holes as the battery temperature control system is very sensitive. This is even more necessary for roads treated with de-icing agents in northern winters, as those chemicals are highly corrosive. Choosing water-based, eco-friendly materials is crucial to avoid toxic gases affecting the cabin air.

The need for underbody armor on new energy vehicles depends on usage. If you mainly drive in urban areas with smooth roads, the factory protection is usually sufficient. However, for frequent road trips or poor road conditions, armor becomes essential. Last year, I experienced underbody scraping, but the armor absorbed the impact. Focus on protecting the battery area rather than coating the entire vehicle—this saves money and reduces weight. Pay special attention to the installation process, as poor workmanship can block drainage holes. During each maintenance check, inspect the armor layer for any detachment to maintain its protective effectiveness.
