A few weeks ago, Ferrari dropped a time bomb with its first electric car, Luce. the car has given to talk at lengthand has generated all kinds of opinions. It is also a vehicle that gives us clues about the direction the brand wants to take in this stage of transition that we are going through. But it is not the only one, because if we delve into the intricate world of patents, Ferrari has registered accounts that would raise some eyebrows.
One of his last patents registered with the United States Patent and Trademark Office (USPTO) is share the CarBuzz medium, which describes a system of photovoltaic panels that deploy from the roof of the vehicle when it is parked. It is not a typical solar roof and has peculiarities that are worth commenting on.
What’s in the patent. The document describe a rollable photovoltaic panel housed in a cavity inside the roof of the car. When the vehicle is stopped and turned off, the panel can be removed through a slot to cover it. According to the technical drawings of the patent, there are two possible positions: one of the panels deploys forward, over the windshield, generating shadow in the cabin; another does it from the rear, under the rear window, oriented at an angle to better capture sunlight. The mechanism uses a U-shaped element and two support rods to extend the panel from its roller.
Why do you do it this way and not any other way? The solution may seem complicated (and it is) compared to simply integrating solar cells into the roof, as some manufacturers already do. But Ferrari seems to have its reasons. First, a roll-up panel that is only activated when parking allows the use of a larger photovoltaic surface than would fit on the fixed roof. Furthermore, the patent explicitly mentions the dual purpose of the system, which is to charge the battery and reduce the interior temperature of the cabin when the car is in the sun.
Along with this, in the patent is pointed out The system includes sensors and weather data to automate when it is deployed or picked up.
Limitations. A solar panel that only works when the car is stationary and in the sun has a very limited range in real life. In the end, the efficiency of these systems depends greatly on weather conditions, the orientation of the vehicle and the exposure time. It is not a fixed place with a large space that allows these losses of efficiency to be counteracted, as is the case in a photovoltaic installation that we can integrate into a house.
CarBuzz mention the case of Hyundai, which has been studying this technology for years and that it integrates into some of its test vehicles. The firm stated that its solar roof can replenish between 30% and 60% of the battery per day in ideal conditions, which for a car with more than 300 kilometers of autonomy could cover the average trip to work. But those “ideal conditions” are the exception, not the norm.
What it says about Ferrari. As we have mentioned before, the patent appears at a very specific time, as Ferrari has just launched the Luce, its first fully electric car, conceived as a vehicle for everyday use and not just as a sports car for occasional use. It makes sense for the brand to start exploring ways to manage autonomy and charging in different ways than conventional ones.
On the other hand, just as points out CarBuzz, adding weight and complexity to the roof goes against Ferrari’s historic philosophy, focused on pure handling and clean design. These are ideas that the brand will have to play with to clarify its priorities in the coming years. However, it should be noted that, at the moment, it is only a patent, not a product announcement. Ferrari, like many other companies, registers technical ideas without necessarily implying that they will reach a production car.
