The arrival of winter and snow create problems for electric cars faster than for those with a combustion engine. Stellantis decided to solve the problem of accumulated snow under the fenders with heaters that are currently in development.
Snow accumulation under a vehicle can significantly impact its safety. The undercarriage, including parts like the suspension, exhaust system, and drivetrain, is particularly vulnerable to the effects of snow and ice buildup. If it is not removed, it can harden into ice, which may get trapped in critical components. For example, ice can freeze the suspension system, making it stiffer and less responsive. This could result in a rougher ride and reduced control over the vehicle, particularly when driving over uneven terrain or on slippery roads.
Furthermore, if snow or ice gets caught around the brakes, it can affect their performance. A build-up of snow in the brake components could block the movement of the brake pads or even freeze brake lines, compromising the vehicle’s ability to stop effectively. This is particularly dangerous in winter driving conditions, where braking is already more difficult due to slippery roads.
To help drivers, Stellantis has come up with an innovative solution. According to information published by the United States Patent and Trademark Office (USPTO), the company is currently working on electrically heated wheel arches, powered by the vehicle’s battery. The heaters would be installed between the vehicle body and the wheel arch liner, which would now protect not only the body surface, but also the heating element itself and its wiring. Stellantis said the heating element would pass through the edge of the fender and melt the ice and snow on its inner surface, or the inner fender. The company’s engineers are also experimenting with a conductive foil that could be placed directly on the inner fender itself.
The data shows that Stellantis intends to use these heaters only in all-electric and hybrid cars, because electric vehicles do not emit enough heat as combustion engines to prevent snow accumulation.
One of the most common issues caused by snow accumulation under vehicles is the increased risk of rust and corrosion. Snow that accumulates under a car often contains moisture, which, when trapped, can lead to the formation of ice. This moisture can easily seep into cracks, crevices, and joints in the undercarriage. Over time, it leads to the development of rust, particularly on metal components that are exposed to the elements, such as the frame, exhaust system, and suspension parts.
Rust not only weakens the vehicle’s structure but can also affect its performance and safety. For instance, rust on the exhaust system can cause leaks, leading to dangerous fumes entering the cabin. If left untreated, rust can compromise vital structural components of the vehicle, resulting in costly repairs.
