[Explanation] At present, electric vehicles are developing rapidly, and relevant data show that China's new energy vehicle production and sales have ranked first in the world for 6 consecutive years, with a cumulative promotion of more than 5.5 million vehicles.
With the rapid growth of the number of electric vehicles, how to ensure the safety and effectiveness of related charging equipment has become an important part of the industry.
[Explanation] On June 10, the reporter walked into the 2021 Xiamen Industry Fair and found that an electric vehicle wireless charging device was on display. I saw a charging plate placed under the electric vehicle, which continued to serve the vehicle through wireless transmission. powered by.
According to reports, compared to wired charging, electric vehicle wireless charging technology solves some of the hidden safety hazards.

Wired charging piles and gun cables are often unplugged. This is easy to cause guns. Because we are electric, it is easy to cause damage to the line at the muzzle. It is easy to cause some people to operate it in case of rain. Improper, it will cause leakage, then wireless charging will not be able to solve this problem.
[Explanation] Wireless charging technology is a technology that uses the principle of near-field magnetic coupling to charge electric vehicles through air transmission. It can realize many practical functions such as parking and charging of electric vehicles and remote control of charging.

(Since the epidemic) Wired charging contacts are something that everyone is more worried about; second, for example, in bad weather, when it is cold or hot, (wireless charging) can be directly connected without getting out of the car and plugging in the gun. You can walk on the parking lot; third, after the wireless charging is on the parking lot, he can go home without plugging in the gun. You can click on the APP to charge when the (electricity) peaks and valleys.
[Explanation] Although the application of wireless charging technology for electric vehicles has not yet become popular, there is a long way to go.
However, as one of the important supporting technologies for electric vehicles in the past five years, there is a huge room for cooperation between wireless charging technology and unmanned driving for electric vehicles in the future.

Once there is driverless, there is no driver. The car has a prescribed route, just like shared bicycles now. It has a fixed place. Then our place, for example, has a wireless charging charging station, and the car ran to it. A prescribed route runs almost out of power, and it comes here (wireless charging station) to charge it by itself.
This imaginary space is very large wireless charging. It is impossible to say that we are only sitting in the car today (wireless charging) and only use it in the car. It is possible that many things will be used in the future. As long as there is no one, it (wireless charging) Can be used.
[Explanation] It is understood that China's "Electric Vehicle Wireless Charging System" series of national standards has been implemented at the end of 2020. This series of standards was formulated against the background of increasingly urgent demand for charging infrastructure for new energy vehicles, mainly electric vehicles. , Enriching China's electric vehicle charging technology system and application scenarios.
