China should accelerate the establishment of wireless charging technology standards for electric vehicles

At present, China's new energy vehicle industry has entered a period of rapid growth, but at the same time, the lack of charging piles has become a major obstacle
to rapid development.
Wireless charging technology with flexible layout, easy to use, charging safety and other characteristics has entered the demonstration development stage
.
However, this technology also faces the constraints
of high cost of use and unification of technical standards.
China should accelerate the establishment of wireless charging technology standards for electric vehicles, promote the demonstration project of wireless charging application of electric vehicles, and increase support for the research and development of related technologies, especially dynamic wireless charging technology, to help the development of
the electric vehicle industry.

Relevant data show that by the end of 2014, the number of new energy vehicles in China has exceeded 120,000, while the number of charging piles is only about 30,000, and the ratio of the two is about 4:1, far from reaching the standard of 1:1
.
The lack of existing facilities, coupled with the rapid growth of new demand, not only brings inconvenience to consumers, but also brings greater challenges
to enterprises and governments.
The new energy vehicle industry urgently needs to find a way
to solve this problem.
The emergence of wireless charging technology provides a new direction, which is expected to solve the problem
of charging pile construction.

So far, wireless charging technology has been commercialized on some portable terminals such as smartphones, and its principle is not complicated, that is, the electric energy is converted into electromagnetic waves at the transmitting end and transmitted, and after the receiving end receives the electromagnetic waves, it is converted into electrical energy and can be charged
.
At present, there are three main ways of wireless charging, namely radio wave type, magnetic field resonance type and electromagnetic induction type
.
Among them, magnetic field resonance and electromagnetic induction are more likely to be used
in wireless charging of electric vehicles.
From the perspective of foreign car companies, Toyota, Volvo, Audi, Nissan, etc.
have begun to develop or test the wireless charging system
of their electric vehicles.
Some companies in global communications and the Internet have also extended their "tentacles" to the new field
of wireless charging of electric vehicles.
