2024 AsiaWireless chargingThe conference was successfully held in Hall 6 of Shenzhen Futian Convention and Exhibition Center on March 21.HongbiaoSong Jiangxing, Senior Certified Customer Manager, attended the site to make a presentation《Qi2Certification Technical KnowledgeHongbiaoThe qualification and business scope of the certified laboratory introduced the current Qi standard and future planning, and sharedQi2Standard certification requirements and processes.
HongbiaoCertification and testing company is a comprehensive third-party testing and certification organization, whose business covers inspection and testing, certification, technical services, and provides one-stop solutions for enterprises.At present, it has electromagnetic compatibility, radio frequency, product safety, vehicle multimedia interconnectionWireless charging, Apple MFI, multimedia digital interface and more than 10 laboratories, with more than 50 professional engineers and service teams.
HongbiaoThe certification test is carried out in strict accordance with the requirements of ISO/EC 17025 quality management system, and has obtained CNASCMA, A2LA, WPC (ATL) and other authorized qualifications have established long-term friendly and stable cooperation and excellent communication channels with many international certification bodies, accumulated rich experience in certification and testing, provided comprehensive services in product certification for thousands of enterprises, and accumulated rich technical experience and advantages.
HongbiaoThe laboratories include Qi laboratory, EMC laboratory, RF laboratory, EMI laboratory and safety laboratory.Qi laboratory covers Qi 1.3 andQi2. 0, including BPP, EPP and MPP.
The current Qi standard, which includes the version of Qi 1.3 introduced in 2021, is the mainstream standard in the current market.Introduced in 2023Qi2Version. 0, magnetic power wireless charging standard.In the future, WPC will launch the mobile coil Tx scheme to solve the problem of aligning the coil and equipment of wireless charging products without magnetic attraction.In 2025, WPC will introduce higher powerWireless chargingAt the same time, intelligent wearable devices will be included in the Qi standard.
Qi2 standard includes EPP and MPP protocols, and no longer includes separate BPP protocols. Qi2 all-in-one products can have BPP.At the same time, Qi2 must contain an authentication chip, and only one core can be used.
MPP protocol has the advantages of more accurate magnet alignment and faster charging effect.With the expansion of WPC's higher power, more products will be introduced to the market.MPP works at 360kHz to prevent interference to other electronic equipment.
The Ministry of Industry and Information Technology has restricted 360kHz, but the problem has not been solved yet. The WPC has continued to communicate with the Ministry of Industry and Information Technology, and submitted an application to ITU, requiring detailed regulations on the use of radio power at 360kHz on a primary/secondary basis.If this route is not feasible, MPP protocol will be used on the replacement frequency that meets the requirements based on the change of standards.
Since the opening of Qi2 standard certification, the WPC has stipulated that magnetic suction products that are not MPP will not pass the certification.
Embedded subsystem products allow OEM/ODM members to use certified Tx subsystems to derive embedded subsystem products through "limited testing".OEM/ODM members can certify products embedded in Tx subsystem for their own brands or other member brands.
Products embedded in Tx subsystem cannot derive similarity certification again.If a product with embedded Tx subsystem is to be branded for non WPC members, it must be certified as a new original product.
OEM/ODM members can certify original products for their own brands or other brands, and the brand is not required to be a WPC member.The cost of certification can be saved by allowing re registration of similarity certification through the original product certification.
The Rx devices supported by MPP include iPhone 13, 14 and 15 series 15W wireless fast charge.
Qi2 certification process: register WPC member → register product Qi ID → obtain product unit certificate → ATL laboratory test → IOP laboratory test → obtain Qi certificate.
Wireless chargingIn the future, the magnetic coupling has a better user experience. Apple leads and Android helps to position the future direction of charging development.In the future, greater power expansion is expected to unify the charging market and expand the market space.
