What kind of experience is wireless charging of electric vehicles? Weilai applied for a patent for wireless charging.

(Text/Zhang Wei) Since Apple introduced the wireless charging function, people really realized the beauty of the wireless charging function. Just put the iPhone on the wireless charger, even Apple? Watches and AirPods can be released at will, that is, they can start charging at the same time. So, can this convenient function be realized in new energy vehicles?

Recently, Weilai Automobile announced the patent application information about "Vehicle Wireless Charging System and Wireless Charging Method". Patent information shows that the wireless charging system includes: a charging transmitter, which is arranged at the charging area side and used for converting electric energy into electromagnetic energy; The charging receiving device is arranged at the upper part of the vehicle and used for receiving electromagnetic energy so as to convert the electromagnetic energy into electric energy for storage; And a first driving device, a second driving device, a control device and the like.

The patent abstract also shows that the patent invention can reduce the installation cost of the wireless charging system, expand its application range, and effectively reduce the annular current generated by the annular conductor of the vehicle when charging.

It is worth mentioning that as early as June this year, the National Standardization Administration Committee issued four national standards for wireless charging of electric vehicles, including "Wireless Charging System for Electric Vehicles Part 1: General Requirements" (GB/T? 38775. 1) Wireless charging system for electric vehicles Part 2: Communication protocol between vehicle charger and charging equipment (GB/T? 38775.2), wireless charging system for electric vehicles Part 3: Special requirements (GB/T? 38775.3), wireless charging system for electric vehicles Part 4: Electromagnetic environment limits and test methods (GB/T? 38775.4), standardization of wireless charging system for electric vehicles.

Of course, in addition to Weilai Automobile, domestic car companies that are also developing and testing wireless charging include mainstream car companies such as SAIC Roewe, BYD and BAIC New Energy, but up to now, there are no production models that support wireless charging in the domestic market. It seems that a dark battle about wireless charging is quietly unfolding.
