The problem of powering electric vehicles has always been at the center of consumer attention. If there is a way to charge cars without stopping, it will become the focus of attention in the market. Now BMW has created such a new patent: not only can their solar panels be mounted on the roof of a car, but in the past, due to the opacity of solar panels, they were usually only able to do so. However, the new patent will allow solar panels to be placed in glass, so whether it's a sunroof, front and rear windshields, or even car windows, solar cells can be coated that can not only help charge a car, but also block parts of a battery pack. .Sunlight enters the car, reducing the load on the air conditioning system, which in turn contributes to a more efficient use of electrical energy.
This new patent is achieved through ultra-thin solar panels. Documents from the German Intellectual Property Office revealed that BMW attempted to place solar charging panels on the roof, hood, front windshield and rear of the vehicle. On the windshield and surrounding windows. This technology is likely to be used on their flagship electric vehicles such as the upcoming XM or iX SUV. Of course, the design of solar charging panels is not a new technology, but such a design will be able to collect more energy than in the past. Among the glasses, it will also give the car an additional advantage. The glasses will have a better thermal insulation effect, which can be said to kill two birds with one stone.
This patent is like sticking a layer of thermal paper with a charging function. It will have up to 95% light transmission at the front to give the driver a good view. For windows and skylights, the coating can be made thicker and the light transmission can be between 50 and 80%. As the coating becomes thicker, more electricity will be generated. However, the downside to this technology is the cost. While BMW hasn't provided an appropriate quote, it's clear that it will be more expensive than current glass and there may be more steps and maintenance costs when replacing glass. However, if the vehicle can have a longer range or even doesn't need to be recharged to charge, this technology will definitely pay off and become the best-selling technology for electric vehicles.
