[Original by Dongchedi Industry] According to foreign media reports, BMW Group recently applied for a new patent from German Patent and Trademark Office (DPMA). This patent can place ultra-thin solar panels on the outer glass panel of the car, which is expected to improve power generation efficiency and significantly reduce direct sunlight in the vehicle. It is reported that this patented technology may be applied to high-end electric models of BMW , including BMW XM, BMW iX, etc.

According to reports, the patent is like pasting a layer of insulation material with charging function on the outside of the car glass. The windshield part in the front of the vehicle will have a transmittance of up to 95%, ensuring that the driver has a good field of view. The side windows and sunroof parts can make the coating thicker, and the transmittance can be between 50 and 80%, and the layer will have more power generation when it becomes thicker.

However, this technology will also greatly increase the cost of the vehicle. Although BMW has not disclosed the relevant quotation yet, it will obviously be more expensive than the current ordinary car glass, and may also incur more maintenance costs in the future.

It is also understood that installing solar panels on vehicles is not new. Since the 1990s, many high-end manufacturers have tried using solar panels, but are usually installed in sunroof panels to power the ventilation system of the car, and this system is still in use today.
