Wireless charging Qi certification types can be divided into three categories: BPP certification, EPP certification and PPDE certification. 1) QI-BPP certification: The product supports less than 5W power, the use of Qi protocol, must be BPP certification. 2) QI-EPP certification: The product supports more than 5W power, the use of Qi protocol, must be EPP certification. 3) Qi-PPDE certification: The product supports more than 5W power, uses Samsung private protocol PPDE, and must be tested by PPDE (from July 1, 2019).
W The above is Qi protocol, thenEPP certification is required (EPP certification is a test item that adds EPP to BPP test items). The Samsung Private Protocol PPDE is an optional feature that manufacturers can add to their QI-certified products. Both BPP and EPP support the addition of Samsung's private protocol PPDE. Once PPDE functionality is added, mandatory testing will be required after July 1, 2019.
Value of Qi certification A wireless charger certified by Qi not only has high quality performance, but also means that it meets internationally recognized technical specifications and can be obtained worldwideWidely accepted. For consumers, choosing products with Qi certification means that they enjoy a stable, safe and efficient wireless charging experience.

Provide specifications and certification applications.
4, Qi certification is only for WPC members, that is, want to do Qi certification must first apply for WMember of PC Wireless Charging Alliance.
Average time for the FCC to process ID applicationsFor 60 days. At the end of the process, the FCC will send the Original Grant of the FCC ID to the applicant. After receiving the certificate, the applicant can sell or export the corresponding products. At least one qualified prototype should be provided for each certified model.
First apply for an FRN, the applicant is the first time to apply for an FCC ID, you need to apply for a permanent Grantee Code; ID of the first application.
About 1 week. FCCSDOC is mainly for IT products, computers and computer peripheral products, this kind of test projectMore complex, the certification cycle is moderate, about 1-2 weeks time.
FCC Certification process The first Certification (that is, application for FCC ID) ① The customer provides a complete test sample and complete accessories, submitted to our laboratory; If it is the first time to apply for an FCC ID, apply for an FCC Registration Number (FRN) at the same time.
Wireless, RF products must apply for FCC ID, computers and computer peripheral products need to apply for FCC DOC or ID, other products oneC Certification. The charger is in the catalogue stipulated in the Regulations on the Management of Compulsory Product Certification. 3C certification is a product conformity assessment system implemented by governments to protect consumers' personal safety and national security, strengthen product quality management, and comply with laws and regulations. Chargers that do not meet 3C certification are not allowed to be sold and used, otherwise they will violate the law.
Therefore, if the fixed wireless telephone described in the "Request" has the functions of the above GSM terminal equipment and CDMA terminal equipment, it should belong to the products within the scope of the CCC catalogue, and the uncertified products shall not be factory, sold, imported or imported without authorizationUsed in other business activities.
1, wireless charger through the WPC Qi certification, can be adapted to all digital equipment supporting the Qi standard in the market, compatibility and versatility in line with international standards, so that wireless charging more convenient. Wireless charger is the use of electromagnetic induction principle, through the coil energy coupling to achieve energy transfer. The resonance principle used is magnetic field resonance, which is transmitted only between coils that are resonating at the same frequencyHis device can't pick up the band.
2, wireless charger export to the EU, in addition to qi also need to do CE certification. The "CE" mark is a safety certification mark that is regarded as a passport for manufacturers to open and enter the European market. CE stands for European unity. All products with the "CE" mark can be sold in the EU member states, without meeting the requirements of each member state, so as to achieve the free circulation of goods within the EU member States.
