Qi is the "Wireless charging" standard launched by the Wireless Power Consortium (WPC). The WPC Alliance was established on December 17, 2008. In 2010. Qi standard 0 was released, and the latest version is V4.
Qi Wireless charging: Qi is a wireless charging standard developed by the Wireless Charging Alliance. The iPhone14 supports 5W of Qi wireless charging and is compatible with any QI-compliant charger. Convenience of Qi wireless charging technologyThe user simply places the phone on the charger and does not need to use a charging cable to start charging.
Qi is the standard of inductive wireless charging technology. The wireless charging standard has two characteristics of convenience and versatility, only the device with Qi logo, can be charged with Qi logo charging equipment. The charging technology wirelessly charges handheld low-power devices such as mobile phones and cameras by electromagnetic induction, providing 5W of charging power for the iPhone12.
The iPhone11 supports Qi wireless charging, and its charging power is 5W. QiWireless charging refers to the use of Qi wireless charging standard protocol for wireless charging of mobile phones. This charging method is based on electromagnetic induction mode for mobile phones, digital cameras, handheld playback devices or other low-power devices. When charging, connect the charger to the power supply, place the phone horizontally on the charger, and wait for the screen to light up the wireless charging is successful.
This means that as long as you use a 5W wireless charger that complies with the Qi standard, you can charge Apple's 11 series phones quickly. Of course, if you use a wireless charger below 5W, the charging speed will be slower.
W, 15W, 5W, etc. 5W: This is the standard wireless charging mode, which provides a more ordinary charging speed. 15W: Fast wireless charging at faster speeds when using Apple's official MagSafe charger. 5W: Some unofficial or low-end devices only support the most basic 5V1A output power, which is similar to the regular socket USB-A5V1A output provided by the standard adapter.
Qi is developed by the Wireless Charging Alliance (The wireless charging standard developed by WPC. The statement on the Internet about the "Apple Qi certification" actually refers to the Apple phone to obtain the Qi certification mark, must pass the Qi certification process. Attention should be paid to distinguishing between related concepts. Qi certification Type Qi certification is divided into the following three types: - Qi-BPP certification: The product supports less than 5W power, using the Qi protocol, must pass the BPP certification.
The Qi standard launched by the global wireless charging technology standardization organization Wireless Charging Alliance (WPC) uses electromagnetic induction technology, has compatibility and universality, and allows the production with the "Qi" logoThe product is charged by Qi wireless charger. The International Wireless Charging Alliance introduced the Qi standard in China in August 2010. To label a product as "Qi" certified, a company must first become a member of the WPC and pay a membership fee.
Qi2 standard is a new generation of wireless charging standard launched by the WPC Wireless Charging Alliance to provide a better charging experience, especially cross-brand operation. The new standard adds more mandatory safety features to protect the interests of users and manufacturers, while reducing the existence of gray markets, and bringing broader market opportunities for certified products.
Wireless chargingThe international standard of the Wireless Charging Alliance is set up by the Qi certification mark to identify compatible products, ensuring that mobile devices such as mobile phones, cameras, remote controls and Qi logo charging dock seamlessly. The alliance is a collaboration of companies from around the world with the goal of making wireless charging easy for all portable electronics.
The wireless Foreigner Object Detect (FOD) function is normalIf a metal foreign body is placed at the launching end, heat will not occur; Heat occurs when a metal object is placed on the transmitting end and the receiving end is stacked on top. Because the electromagnetic field will generate eddy current on the foreign body of the metal, it will heat the foreign body of the metal, resulting in a dangerous meltdown of the shell.
Identify QI standard: Wireless charging currently has two major international mainstream industry standards. One is the QI standard of the Wireless Charging Alliance (WPC), and the other is the AirFuelAlliance. These two standards regulate the energy, technical parameters, compatibility, and safety of wireless charging productsIt has strict certification standards.
Foreign bodies usually refer to metals with magnetic properties, that is, magnetic substances. When such substances are in a change of magnetic field, according to the eddy current effect, an electric current is formed inside the metal, causing it to heat up. This means that when there is a magnetic substance on the wireless charging board, it may lead to a loss of energy, which poses a potential threat to the receiver and transmitter of wireless charging.
Compliance testing includes the communication protocol between the transmitter and the receiver, the ability to move on the XYZ axis, the energy transmission ability, foreign object detection and many other aspects. Compatibility test ruleEnsure that each Qi certified device and charger can work together, support products from different manufacturers, and be compatible with products under the Qi standard. Products that pass these two tests ensure a safe and reliable wireless charging experience.
-Qi-BPP certification: The product supports less than 5W power, using the Qi protocol, must pass the BPP certification. - Qi-EPP certification: Product support 5Power above W, using Qi protocol, must pass EPP certification. - Qi-PPDE Certification: Products support more than 5W power, use Samsung private protocol PPDE, must be tested by PPDE (implemented from July 1, 2019). Certification options Depending on which certification is selected, it depends on the power supported by the product.
QI certification is a certification standard for wireless charging products, developed by the Wireless Charging Alliance (WPC). This certification ensures that wireless charging products meet specific safety and performance standards. How do I get QI certification? To obtain QI certification, noneLine charging products must first be licensed by the WPC. This includes registering as a WPC member, paying a membership fee, and submitting products for the certification process.
QI certification means the standard certification of the Wireless Power Supply Technology Alliance. QI Certification Overview QI certification is a set of standard certification developed by the Wireless Power Supply Technology Alliance. With the continuous development of wireless technology, wireless charging function has been widely used in mobile devices such as smart phones and tablet computers. In order to ensure the wireless charging functionality and security of these devices, WPC has launched the QI certification standard.
MemberApplication: First of all, become a full member of the WPC and obtain the qualification to participate in the certification. Product registration: Submit product information for registration. Product availability: Submit samples for testing. Compliance and compatibility testing: Strict quality and functional testing of products to ensure compliance with standards. Final confirmation: After passing all tests, the product is confirmed to be correct. Audit and certification: Finally, after the authoritative audit, issued Qi certification.
Wireless Charging QI certification is an international standard established by the Wireless Charging Alliance (WPC Alliance) to ensure that electronic products with the Qi logo are compatible with the charging base. The Qi logo represents the productIt has been rigorously tested to ensure safety, interoperability and energy efficiency. The product range covers all electronic products with wireless charging function, and the transmitter and receiver need to be certified.
The Qi standard launched by the global wireless charging technology standardization organization Wireless Charging Alliance (WPC) uses electromagnetic induction technology, has compatibility and universality, allowing products with the "Qi" logo to be charged through Qi wireless chargers. The International Wireless Charging Alliance introduced the Qi standard in China in August 2010. To mark a product as "Qi" certified, a company must first become a member of the WPC and pay for it
