New wireless charging standard Wireless charging protocol certification : In-depth analysis of Qi certification wireless charging technology Wireless charging protocol certification Popularity Wireless charging protocol certification is inseparable from strong technical standard support. Qi certification, full name Qi Wireless Charging, is developed and implemented by the Wireless Power Consortium (WPC)Global wireless charging standard.
Wireless charging Qi test includes Compliance Test (Compliance test) and compatibility test (Interoperability Test), the compliance test is conducted by the ATL (Authorized Test Lab), sending 5 samples.
Qi standard, PMA standard. Qi standard: It has two characteristics of convenience and versatility. Different brands of products, as long as there is a Qi logo, can be charged with Qi wireless charger. Cell phones, cameras,Computers and other products can be charged with Qi wireless chargers. PMA standard: Wireless charging standard developed in the United States, with a number of security protection measures.
Qi2, is an innovation in the field of wireless charging. Since its inception in 2008, the WPC Wireless Charging Alliance has been committed to promoting the standardization of wireless charging technology worldwide. Based on the Qi 3 protocol, the Qi2 standard introduces the MPP protocol and magnetic alignment technology, the operating frequency is increased to 360kHz, the foreign body detection function is enhanced, and the MPP and EPP modes provide 15W efficient transmission capacity, and the future is expected to achieve higher powerWireless charging.
qi2 wireless charging means a new enhanced wireless charging standard. The biggest experience difference QI2 brings to users is that the use of QI2 certified wireless charging devices can provide 15W charging experience to devices that support QI2. WPC sees QI2 as a significant opportunity in 23/24. Qi2 is a new enhanced wireless charging standard developed by the WPC Wireless Charging Alliance in 2023.
During the test, the receiver needs to establish communication with the transmitter in a short period of time, and charge steadily for 5 minutes under the condition of low battery power. This high-standard test undoubtedly improves the market competitiveness and user trust of Qi certified products. 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 widely accepted around the world.
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).
Do wireless charging Qi certification first if the WPC wireless charging alliance member, and then apply for QI ID, the list of member fees is as follows: WPC charging allianceQi Standard 0 was released in July 2010, the current version is V4, and the WPC Charging Alliance is expected to launch the latest version V3 in the fourth quarter of 2019.
Qi certification refers to the certification of wireless charging standards established by the Wireless Charging Alliance (WPC). The Wireless Charging Alliance (WPC) is a global organization dedicated to developing and promoting standards for wireless charging technology. The wireless charging standard developed by the organization is called the Qi standard, and any charger with the Qi logo can wireless charge any rechargeable device that meets the Qi standard.
Qi is the "Wireless charging" standard launched by the Wireless Power Consortium (WPC); It has two characteristics of convenience and versatility. Qi certification test standard Qi standard 0 was released in July 2010, the current version is V4, the WPC charging Alliance expects the latest version V3 around April 2020 (there is likely to be a 3-6 month delay), the full V3 specification was released in WPC2001.
Qi certification, will pass the wireless charging alliance security,Validity and compatibility testing. Qi certified devices must operate at 0-30 watts (Qi standards can reach 1 kilowatt, but not for mobile phones), pass temperature tests, and comply with Qi FOD standards. They also need to be compatible with all other QI-certified devices (phones or chargers), just like all Micro-SD cards are compatible with all Micro-SD ports.
2, the average time for the FCC to accept ID applications is 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. everyQuality is made on the basis of Qi private transformation, support magnetic absorption, power can be up to 15W.
2, Yes. Apple wireless charging protocol is qi, 12 series of wired charging support pd, but to buy a c port charger, Apple from the iPhone8 began to apply wireless charging, has only expanded open 5W battery charging output power, compared with other mobile phones in the same industry, this output power is not high, belongs to an ordinary output power level.
3, this model of mobile phone can be wireless charging. According to the IT encyclopedia query, Apple 11 supports Qi wirelessCharging protocol, only need to support the protocol wireless charger and mobile phone connection, wireless charging can be carried out. However, it should be noted that the Apple 11 does not come with a wireless charger, and users need to purchase it themselves. Wireless charging uses magnetic induction to charge the iPhone 11, eliminating the need for a charging cable to connect the phone to the charger.
4, the release of the iPhoneX let us enter the era of Apple wireless charging. Apple uses the internationally accepted Qi wireless charging technology for wireless charging of its mobile phones and related products. Qi wireless charging refers to the application of Qi wireless charging standard in the way of electromagnetic inductionWireless charging technology for handheld low-power devices such as mobile phones and cameras.
5, the wireless charging protocol generally supports the qi protocol, if the wireless protocol of the charger is supported, then it can be charged.
Wireless charging Qi certification types can be divided into three categories Wireless charging protocol certification : BPP certification Wireless charging protocol 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 If the above is the Qi protocol, it needs to be certified according to EPP (EPP certification is a test project that adds EPP wireless charging protocol certification on the basis of BPP test project). 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 Obtain Qi certification for wirelessThe charger not only has high quality performance, but also means that it meets internationally recognized technical specifications and can be widely accepted worldwide. For consumers, choosing products with Qi certification means that Wireless charging protocol certification They enjoy a stable, safe and efficient wireless charging experience.
Yes belongs to the three no factory products, apply for Qi certification. The application process is as follows: 1) Membership application; 2) Product registration; 3) Product provision; 4) Product compliance testing; 5) Product compatibility test; 6) Final product confirmation; 7) Review and sendCertificate. Compatibility testing laboratory IOC: there are two in the world, namely Eurofins in Hong Kong and TTA in South Korea. Special reminder: Starting from July 1, 2019, products support more than 5W power, using Samsung private protocol PPDE, must be tested by PPDE.
