Jinan Photovoltaic Highway Can Be Wirelessly Charged

Edit:Shenzhen Keliway Technology.,LtdUpDate:Apr 14, 2018

    In recent years, photovoltaic highways have become the new direction of research and development in the transportation sector in various countries. Photovoltaic highways in Jinan, China have also attracted the attention of foreign media. According to foreign auto blog autoblog.com reported on April 20, a pilot experiment was held in Jinan in 2017. With the opening of the photovoltaic highway, this section of road can not only generate electricity, but it can also be used to charge electric vehicles that drive on the road.

    According to reports, this trial road was reconstructed by Qilu Transportation Development Group Co., Ltd., with a total length of 1,120 meters. The length of 1080 meters of photovoltaic roads was laid, and the main carriageway and emergency lanes were laid. The width of the main carriageway is 3.75 meters, of which photovoltaic roads occupy 3 meters. The width of the emergency lane is 3 meters, of which the photovoltaic road width is 2.44 meters. The total net area of PV pavement is 5,875 square meters, and the peak installed capacity of distributed grid-connected power generation is 817.2 kilowatts. It is estimated that the annual power generation will be about 1 million kilowatt-hours. Enough to provide lighting for the highway and 800 homes.


    According to reports, the road surface of this photovoltaic road is divided into three layers. The surface is in contact with the pedestrians of the vehicle. The transparent layer is used for the protective layer. The surface is also paved with inductive charging components and various sensors to monitor the temperature and traffic flow. weight. The middle layer is laid with photovoltaic cell power generation components that can use sunlight to generate electricity; the bottom layer is an insulating layer that blocks moisture from below. The design load is based on the current national highway standards; the design service life is based on the asphalt pavement design specification standard for 15 years; and the design load capacity is 24 million ESAL equivalent standard axle loads. The design life and road performance indicators are higher than the existing asphalt concrete pavement.

    In the long run, the goal of photovoltaic roads is to form a more intelligent transportation system. In the future, it will be able to provide more accurate traffic information and high-precision maps, and even wireless charging during vehicle driving. Some netizens commented that if they can achieve this goal, this is simply a super solar charging treasure.


    However, the current comprehensive roadmap for the development of intelligent roads has not yet been determined. The first issue is the cost. The current cost of such photovoltaic roads needs to be RMB 996 per square meter, and in the future, the cost will drop to RMB 2,996. . Zhou Yong, general manager of Qilu Transportation Development Group, said, "From a technical point of view, charging itself is not a problem, but the current car that can be wirelessly charged has not yet been used in practice." In addition, the company stated that it is currently working with a domestic automobile manufacturer. The company cooperated in research and development of this application, but did not disclose the name of the partner.
