1, QI certification is a certification for wireless charging products, which belongs to the wireless charging Alliance WPC. To use this logo on wireless charging products, you first need to get the authorization of WPC, register as a WPC member, pay the membership fee, you can apply for QI certification. Qi is pronounced "chee" and its name is derived from an Asian philosophy that means "key energy", an invisible energy.
2, Qi certification: the universal language of Wireless charging industry Qi, the full name of wireless charging alliance (Wireless PowThe work of the er Consortium, or WPC, defines a universal standard for wireless charging. 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, Qi certification, full known as Qi Wireless Charging, is a global Wireless charging standard developed and implemented by the Wireless Charging Alliance WPC (Wireless Power Consortium). It is designed to ensure interdeviceEfficient and safe wireless charging experience, whether it is mainstream solution providers such as IDT, Qualcomm, Texas Instruments, or terminal manufacturers such as Samsung, Philips, etc., are jointly involved in its promotion.
4, QI certification is the WPC Wireless charging alliance Wireless Power Consortium recognition and authorization mark, obtained the WPC alliance certified products, Please use other receiving devices that support wireless charging Try please use other receiving devices that support wireless charging such as Mate20 pro, P30.
Qi is a Wireless charging standard created by the Wireless Power Consortium (WPC), its biggest feature is based on electromagnetic induction technology, strong compatibility, to achieve charging between different brands, different designs of equipment. In addition, the Qi standard also supports the simultaneous charging of multiple devices, automatic control of charging power and charging protection, which improves charging efficiency and safety, and brings a convenient, efficient and reliable experience for people to charge.
qi is the world's first standardization organization to promote wireless charging technology - wireless chargingThe "Wireless charging" standard launched by the Wireless Power Consortium (hereinafter referred to as the "Alliance") has two characteristics: convenience and versatility. First of all, different brands of products, as long as there is a Qi logo, can be charged with Qi wireless charger.
Qi wireless charging refers to the application of Qi wireless charging standard in the way of electromagnetic induction for mobile phones, cameras and other handheld low-power equipment wireless charging technology. The Qi Wireless charging standard was developed by the Wireless Power Consortium (JaneCalled WPC) initiated and developed, is currently the world's widely recognized wireless charging standard. Including Apple, Samsung, Nokia and other world-class enterprises to Qi standard as their terminal equipment wireless charging technical standards.
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 the certification requirements of a technical organization, similar to SIG's Bluetooth BQB certification. And the regular national or regional certification does not have a direct relationship, that is, do oneCan be used all over the world.
Apple wireless charging protocol is as follows: Qi wireless charging protocol: Qi is the wireless charging standard launched by the International Wireless charging Alliance, most of the mobile phones, TWS Bluetooth headsets, tablets and other devices that support wireless charging are Qi wireless charging protocol. Since the iPhone 12, Apple has joined the MagSafe wireless charging protocol, which is essentially a private transformation on the basis of Qi, supporting magnetic absorption, and the power can be up to 15W.
1, wireless charger usage: the mobile phone standard charger and data cable connected to the wireless charger, and then the mobile phone is/horizontally placed in the wireless charger base left and right center position, you can achieve wireless charging, the indicator light will have a breathing effect, 5 seconds after the extinguish, plug and play, convenient and quick. 2, there are four main ways to achieve wireless charging, including the use of electromagnetic field interaction, radio wave transmission and other principles to achieve current transmission. Do these terms sound as confusing as reading a physics book? Let's read them one by one. The first is field-coupled charging.First, there are two sets of asymmetrical electric dipoles on the phone and charging device. When they are close together, they produce a coupling phenomenon and achieve the transmission of current.
3, electromagnetic induction The most common way of wireless charging is to use the principle of electromagnetic induction, through the primary and secondary coil induction to generate current, so as to transfer energy from the transmission end to the receiving end. This approach has been achieved by the Wireless Charging Alliance (Wireless? The Power? Consortium; WPC).
4, At present, there are four main technical ways to achieve wireless charging: magnetic induction technologyMagnetic resonance technology, microwave technology and electric field coupling technology. Among them, magnetic induction technology and magnetic resonance technology are the technologies that are basically used in the current mass production products. 5, in general, according to the current wireless charging methods and implementation principles of mobile phones, it is generally divided into three categories, magnetic resonance, electromagnetic induction and radio waves. Now, the most used is electromagnetic induction. Compared with the other two wireless charging methods, electromagnetic induction technology is more mature, charging efficiency is higher than other ways, followed by his implementation structure is simpler and more stable operation.
