Qi2 is a new enhanced wireless charging standard developed by the WPC Wireless Charging Alliance in 2023. It incorporates Apple's Magnetic Power Profile (MPP) technology to provide a better wireless charging user experience and pave the way for the development of new features and enhancements in the future.
The core of Qi2 technology is MPP certification, which requires all products to be equipped with an authentication chip, which is assisted by MCSP to complete the certification process. The Qi2 standard covers areas such as smartphones, kitchen appliances, electric vehicles and industrial equipmentThere are many certified products. China has the largest number of members, followed by the United States, and other countries and regions also have a certain proportion. Qi certification process is rigorous to ensure product compatibility and safety.
Qi2 charger is a wireless charging device based on the Qi standard, which uses electromagnetic induction technology to provide wireless charging capability for electronic devices. Qi is the world's first wireless charging standard, launched by the Wireless Power Alliance (WPC). It uses electromagnetic induction technology to transmit electrical energy from the charging device to the receiving device. The Qi standard aims to achieve the standardization and universality of wireless charging, so that different brands and models of equipmentWireless charging via Qi standard.
is different. Qi2 is the latest wireless charging standard officially released by WPC (Wireless Charging Alliance) on March 21, 2023. Compared to the previous Qi1 protocol, Qi2 introduces MPP (Magnetic Power Profile) technology, based on the development of MagSafe magnetic charging technology. This updated standard is designed to provide a better wireless charging user experience, paving the way for the development of new features and enhancements in the future.
Qi2 has a maximum charging power of 15W, while Qi1 has a maximum charging power of 5W. This means that QThe i2 provides a higher current when charging, which speeds up charging. In the case of wire alignment, Qi2 is expected to provide higher charging speed, while Qi1 is relatively slow charging speed. Qi2 is designed for smartphones, but also works with all electronic devices, while Qi1 initially only supports smartphones.
Qi2 Wireless Charging Protocol is the latest wireless charging standard from WPC that brings faster wireless charging speed, versatility and compatibility to handheld and mobile devices. Qi2 charging devices can be aligned and carried out much faster using magnets, just like existing MagSafe accessoriesCharge up. Compared to the previous Qi standard, Qi2 uses magnetic power profile technology, which claims to ensure the perfect match between the device and the charger, thus improving energy efficiency.
1, QI-BPP certification: The product supports less than 5W power, the use of Qi protocol, must be BPP certification. Qi-epp certification: The product supports more than 5W power, the use of Qi protocol, must be EPP certification. Qi-PPDE certification: The product supports more than 5W power, using threeStar Private protocol PPDE, which must be tested by PPDE (effective July 1, 2019).
2, Qi certification application process certification preparation stage: customers apply to become WPC members; Customer prepares product conformity statement (specified format); Customer submits declaration of conformity and test samples; The certification service agency confirms the samples and materials submitted by the customer; Customer orders and completes payment. Certification stage: the certification service body starts the compliance test; Certification services submit test samples for interoperability testing; The certification service agency completes the test and issues the test report.
3,QI certification is the Wireless charging alliance certification, formerly known as WPC certification is the first letter of the Wireless Power Consortium (Wireless charging Alliance), which belongs to a technical organization's certification requirements, similar to SIG's Bluetooth BQB certification. It is not directly related to conventional national or regional certification, that is to say, it can be used globally.
4, wireless charger is required to 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 compatibilityA surname '> What does qi certification include?
1, final product confirmation; 7) Review and issue certificates. Qi certification process Wireless charging Qi certification test includes: Compliance test and Interoperability Test. The compliance Test is conducted by the Authorized Test Lab (ATL), and 5 samples are sent for test.
2, Qi certification test content detailed Qi certification test content is rigorous and comprehensive, mainly includesCommunication protocol between transmitter and receiver: to ensure that both sides can exchange data quickly and accurately. Power output and stability: In the XYZ axis translation test, verify the wireless charging capability of the device at different angles. Energy transmission limit: Test the maximum power supply capacity of the equipment to ensure safety performance.
3, wireless charging Qi certification content: including Compliance test and Interoperability Test. Compliance testing by Compliance Testing Laboratory ATL (Authorized Test Lab), 5 samples were sent for testing.
4, wireless charging Qi certification test includes Compliance test and Interoperability Test. The compliance Test was conducted by the Authorized Test Lab (ATL) with 5 samples.
5, mobile phone Qi certification Test includes Compliance test (Compliance Test) and compatibility test (Interoperabili)ty Test). The conformance test mainly includes the following: coil design test; Timing test; Power assurance test; Foreign Object Detection (FOD); User indicates testing.
6, 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).
