Wireless charging road: Do you still have to realize your dreams?

In order to achieve sustainable energy development, humans invented new energy vehicles; and then in order to solve the problem of efficient and convenient endurance of new energy vapors, humans have racked their brains and invented fuel cells, solar charging, charging piles, power stations, etc. . However, great scientists are more mad about the future of electric vehicles: in the future, they will no longer see gas stations, charging stations, wireless charging roads, and no need to refuel, no parking, charging, running on the road, no Let go of the rest.

Electric Jun seems to have entered the illusion of Hollywood technology blockbusters. No matter how awkward it sounds, don't forget, the great Ma Yun told us: Dreams still have to be, if it is realized?

Wireless charging has long been nothing new, and wireless charging of electric toothbrushes, remote controls, smartphones, and tablets has become commonplace in our lives. In the wireless charging technology of electric vehicles, Audi, BMW, Mercedes-Benz, Toyota, Volvo and other car companies, Qualcomm, ZTE, Siemens and other communication companies have been reported by the media to study electric vehicle wireless charging technology.

"Electric Vehicle Times" was informed that the British government plans to invest 500 million pounds in the next five years to pilot a nationwide wireless charging device for electric vehicles. If it succeeds, it will implement this technology on British highways and main roads. Thereby, the bottlenecks such as charging difficulty and long charging time faced by the electric vehicle in long-distance driving are cracked. In the future, electric vehicles and hybrid vehicles will be able to obtain endless driving distances without stopping the parking when driving on the main streets, and bid farewell to the “shutdown” caused by “low battery”.

As early as 2013, Electric Jun heard that Volvo had established a 1/4-mile track in the Swedish test center, testing it with a truck, and wanted to realize the desire of electric vehicles to charge while charging. However, time flies, almost three years have passed, and there has been no update on the Volvo wireless charging road.

However, in 2013, the Gumi City Railway Station in the south of South Korea reached a 12-kilometer road in the In-dong area, becoming the world's first wireless charging bus lane. It has already been charged while the electric bus is driving. The principle is that the cable installed under the road surface can generate an electromagnetic field, and a coil in the bus equipment will interact with it to generate electric energy. At present, there are 2 buses that provide transportation and passenger services to the public on this wireless charging road, without parking or refueling.

It is obviously unrealistic to construct all roads into wireless charging roads. If a special wireless charging lane for public transportation such as buses, taxis, etc. is built in the city, the problem of public transportation due to excessive charging time will be completely solved. South Korea has successfully tested the wireless charging road in 2013. Why is there no longer a wider promotion? According to the electric king, the cost of building wireless charging is relatively high, and the practicality is far lower than that of charging piles or overhead cables. It is too expensive to promote the input cost in a large scale. The high cost investment is obviously contradictory to the resource conservation and environmental protection that we advocate.

Assume that the wireless charging road can be promoted and promoted, the magnetic field charging board is installed, the road needs to be excavated and rebuilt, and the operating cost, maintenance cost and use cost of the built charging road are high. How to charge the owner? If the cost of use is too high, how can the problem of no market demand caused by the choice of electric vehicle owners not to use? How to prevent the gasoline car from occupying the charging road? These are all kinds of problems that need to be solved.

Regardless of whether the wireless charging road is a more effective way to promote electric-powered vehicles, its construction needs to face too many popular problems, such as road construction, design problems, current collectors, and electric vehicle support. Wireless charging road technology does have great potential, but it is a huge project, not 500 million, 10 billion or individual car companies can promote the development, electric Jun seems to be too long to implement the wireless charging road The way to go. Of course, the dream is definitely there!
