The China Electricity Council (CEC) has approved and released a set of national standards for wireless charging of electric vehicles, which will be based on magnetic resonance developed and patented by WiTricity, a Massachusetts-based wireless power transmission expert. technology. The lack of standardization has always been a major obstacle to the popularity of wireless charging, but it seems that in the near future, not only China and the world will use the same standard, which will help promote the popularity of wireless charging.

The new standard is divided into four parts in the GB/T 38775 document to describe the standard
General requirements< /p>
Communication protocol between vehicle charging device and wireless charging device
Special requirements
Electromagnetic environment limitations and testing methods
In the past few years, WiTricity works with automakers and Tier 1 suppliers in China. Companies that have licensed WiTricity technology include Zhejiang VIE Technology Co., Ltd. (VIE) and Suzhou Anjie Co., Ltd. (Anjie). VIE has begun to provide wireless charging system testing facilities for OEM manufacturers, and Anjie introduced the relevant details of wireless charging to Xpeng Motors. It's unclear whether the technology will become a mainstream standard, which will affect the cost of applying it. Another issue is efficiency. How much power will be lost during charging is a matter of concern.
