Mercedes transforms the body into a source of energy

The automotive sector continues to look for solutions to optimize the energy efficiency of electric vehicles. In this dynamic, Mercedes-Benz has unveiled a major innovation: solar paint capable of producing energy to recharge the batteries of electric cars. This revolutionary technology promises to reduce reliance on charging stations, a significant constraint for many electric vehicle users.

How does this solar paint work?

Baptized Solar Coatingthis paint is based on the integration of photovoltaic nanoparticles in a thin layer of 5 micrometers. These particles capture sunlight to convert it into energy. The paint is made up of two layers: an active base which captures light and a transparent varnish which maximizes the transmission of solar rays. Everything is designed to preserve the aesthetics of the vehicles while providing this new functionality..

Unlike adding solar panels to the roof, this paint covers the entire body of the vehicle, thus increasing the solar collection surface and improving overall efficiency.

How much additional autonomy can we expect?

The performance of this technology varies depending on several factors, including vehicle model, weather conditions and usage habits. Mercedes-Benz puts forward figures between 7,400 and 12,000 additional kilometers per year in optimal conditions. These variations can be explained by differences in the intensity of sunshine depending on the region or by the size and energy efficiency of the equipped vehicle..

For example, in a city like Stuttgart, where sunlight is moderate, this paint could cover up to 62% of daily energy needs for an average journey of 52 kilometers. On the other hand, in sunnier regions, the gains could reach their maximum, offering drivers almost daily autonomy without external charging.

An ecological and promising technology

In addition to its performance, this innovation is part of an environmentally friendly approach. The paint does not contain rare earths or silicon, materials often criticized for their polluting extraction. In addition, Mercedes ensures that the manufacturing process does not use toxic substances, thus reinforcing its commitment to sustainable mobility.

However, some questions remain unanswered. How will this paint react to climatic hazards or small everyday accidents? Mercedes will also have to prove the economic viability of this technology and ensure that its maintenance does not become a burden for users.

A revolution for electric mobility or a project in the making?

With this innovation, Mercedes-Benz once again demonstrates its ability to push technological boundaries. By offering a solution that is both discreet and effective for extending the range of electric vehicles, the German manufacturer is tackling one of the main obstacles to their mass adoption. However, large-scale integration of this technology will depend on its sustainability, cost, and market reception..

If fully exploited, this solar paint could become a standard in the automotive industry, paving the way for a significant reduction in the carbon footprint of electric vehicles.
