Recently, a "three-in-one" super road integrating "photovoltaic solar power generation + mobile wireless charging + unmanned intelligent driving" was released to the world in the Lanting Industrial Park in Shaoxing. Once this road was released, it quickly swept the screen in the circle of friends with the imaginative black technology, becoming the super "net red" in the photovoltaic industry.
"Three in one" global initiative
It is understood that the super road is 98 meters long and 3.75 meters wide. It combines more than a dozen black technologies. In addition to key technologies such as photovoltaic power generation, wireless charging and driverless driving, it also has energy storage, radiation protection and intelligence. Identification and other supporting technologies. The super road can not only generate electricity, but also charge electric vehicles wirelessly. In addition, the stored photovoltaic power can also be used for pavement lighting, cold weather and other facilities.
The photovoltaic road that can generate electricity is not the first time in front of people. The concept of “photovoltaic road + wireless charging” is not the first time, but there is never a photovoltaic road that can truly achieve “photovoltaic solar power + mobile wireless charging”. +No intelligent driving" three in one. It can be said that the "three-in-one" super road satisfies all the illusions about photovoltaic roads. However, it is worth mentioning that, according to previous experience, although the photovoltaic road is full of gimmicks, there are still many problems in the application side.
In fact, the concept of photovoltaic roads has been proposed more than a decade ago and is sought after by the world. For more than a decade, many photovoltaic roads have emerged around the world. In 2014, the world's first solar road was introduced in theNetherlands. The road is only 70 meters long and only allows pedestrians and bicycles to go on the road. In 2016, the first French road made up of solar panels was built and trial operation. The solar road is 1 km long.
Compared with foreign countries,China's exploration in the field of photovoltaic roads has also reached the forefront of the world. At the end of last year, the first section of the domestic photovoltaic road was officially opened to traffic. This section of the highway is a section of expressway in Jinan with a total length of 1.1 kilometers.China's photovoltaic highways in Jinan have created a number of records, both in terms of cost of construction and power generation efficiency are at the forefront of the world.
But this road, which carries the huge expectations of PV people, has not given good results in terms of practicality. According to reports, the section of the road was deliberately destroyed after a week of traffic. What is even more disappointing is that the section of the expressway was seriously damaged after half a year of operation, and closed maintenance became the norm. In only half a year, the road surface of this section has been mottled and its quality is facing a huge test. Not long ago, it was reported that the section of the photovoltaic expressway was being demolished and subsequently rumored. The relevant project leader said that the photovoltaic road was not dismantled, but it was prepared to upgrade and update on the basis of the previous road surface.
At the beginning, when the first PV highway was opened to traffic inChina, the PV industry people cheered, but did not expect it to face the current quality dilemma.
Compared with China's first photovoltaic road, the “three-in-one” super road that has received attention recently has increased the emerging elements such as wireless charging and smart driving, but this is still only a trial product, and the related technology is still not mature enough. In the actual road. For example, the energy storage efficiency, wireless charging efficiency, and intelligent driving safety of the road have yet to be tested. It is precisely because of this that this “three-in-one” super road is currently only applicable to large-scale plazas and closed roads in tourist attractions.
Although the practicality of photovoltaic roads needs to withstand more tests, our practice and exploration in this field has already taken the lead in the world. Relying on the leading position ofChina's PV industry in the world and the world's most highway mileage, PV roads have great future prospects. Once the relevant technology is mature, PV roads will bring changes to the wayChinaand even the world travel.
At present, the quality problems faced by photovoltaic roads mainly depend on bearing and anti-corrosion. How to develop new materials, maintain translucency, and ensure the strength and quality of pavements is a difficult problem for related companies. On the other hand, the replacement of fuel vehicles by new energy vehicles is a general trend. However, wireless charging is not yet widely used in the field of new energy vehicles. Therefore, wireless charging technology is still difficult to apply to photovoltaic roads. Overall, the PV road is not a gimmick, it has been practiced, and is breaking through various problems. I believe that the technology will mature soon and will be widely promoted. Wireless charging technology and intelligent driving are not yet mature, but the future must be Can shine. The "three in one" super road is not a gimmick but a future.
