1, Qi wireless charging certification includes the following: 1) membership application; 2) Product registration; 3) Product provision; 4) Product compliance testing; 5) Product compatibility test; 6) Final product confirmation; 7) Review and issue certificates. Qi certification process Wireless charging Qi certification test includes: Compliance test and Interoperability Test.
2, Qi certification test content detailed Qi certification test content is rigorous and comprehensive, mainly including: transmitterCan not be separated from strong technical standard support. Qi Certification, full name Qi Wireless Charging, is a global Wireless charging standard developed and implemented by the Wireless Power Consortium (WPC).
2, wireless Qi test includes Compliance Test (Compliance test) and compatibility test (Interoperability Test), compliance test by the compliance test experiment ATL (Authorized Test L)ab) Carried out, 5 samples were sent for testing.
3, 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. Mobile 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.
4, Qi2, is an innovation in the field of wireless charging. The WPC Wireless Charging Alliance, founded in 2008, is dedicated to advancing wireless charging technology worldwideStandardization. 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 power wireless charging.
5, 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 thinks QI2 is going to be 23/24 years of a major business opportunity. Qi2 is a new enhanced wireless charging standard developed by the WPC Wireless Charging Alliance in 2023.
1, Qi certification testing content detailed Qi certification testing content is rigorous and comprehensive, mainly including: transmitter and receiver communication protocol: to ensure that both sides can quickly and accurately exchange data. Power output and stability: In the XYZ axis translation test, verify the wireless charging capability of the device at different angles. Energy transmission limits: TestingThe maximum power supply capacity of the device to ensure safety performance.
2, Qi certification: the universal language of Wireless charging industry Qi, the full name of the wireless charging Alliance (Wireless Power Consortium, referred to as WPC) masterpiece, it defines a global universal wireless charging standard. This standard is "convenient" and "universal" as the core, ensuring that different brands of products only need to have the Qi logo, can be seamlessly connected with any QI-compatible wireless charger.
3, wireless charging Qi certification content: including compliance testing (Compliance test and Interoperability Test. The compliance Test was conducted by the Authorized Test Lab (ATL) with 5 samples.
4, 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). Special reminder: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.
5, and is considered to be "Qi certified" products. 1) By coil type: Single coil: A11, A11a; Multi-coil: A28; 2) Divided into charger products according to common products; Mobile power supply products; Embedded device (product contains TX emission function).
6, wireless charging Qi test including compliance test (Compliance test and Interoperability Test, the compliance Test is conducted by the Authorized Test Lab (ATL), which will provide 5 samples for testing.
You are advised to connect to a stable network and try. Note: Game card immediately, if the secondary card (notData card) has received SMS, MMS or calls, the mobile data network of the main card (data card) will be temporarily interrupted, at this time the game will appear the picture lag or drop the line and other phenomena, which is a dual-card dual-waiting single-pass mobile phone feature.
After the game frame insertion is enabled, the picture has a sense of delay/the picture does not follow the hand, and the phenomenon of touch screen delay is because the game frame insertion function can increase the frame rate or reduce the power consumption in the corresponding game scene, thus bringing an excellent game experience of high frame rate, optimized heating, and controlled power consumption, but there will be a slight touch screen delay when the frame rate increase or stable frame rate is enabled. At present, models using independent display chips have a similar phenomenon,You can observe and use the game after closing the frame as needed.
You are advised to connect to a stable network and try.
