1, the principle of wireless charging technology is that "magnetic electricity.In simple terms, the charging device and the two pieces of "magnetic equipment" installed on the mobile phone device are induced to each other and form a current. At present, products supporting wireless charging have appeared in mobile phones, electric vehicles, smart furniture and other fields. Among them, in the mobile phone industry, the "Qi standard" is the most common, and Qi labels are often used in the packaging of many mobile phones and wireless chargers.
2, wireless charging system mainly uses the principle of electromagnetic induction. Wireless charger refers to the charger that does not need to be connected to the terminal device that needs to be charged without the traditional charging power cord, and uses the latest wireless charging technology to enableUsing the magnetic field generated between the coils to magically transmit electrical energy, inductive coupling technology will become a bridge connecting charging base stations and devices.
3, the basic principle of wireless charging is to convert the current into a magnetic field, and the magnetic field is transmitted through the air and then converted into a current to be transmitted to the intelligent terminal. When the system works, the input end converts the AC mains into direct current through the full bridge rectifier circuit, or uses the 24V direct current end to supply power to the system directly. After passing through the power management module, the output direct current is converted into high-frequency alternating current through the 2M active crystal oscillator inverter to supply the primary winding.

Through electricityThe DC power output after the source management module is converted into high-frequency AC power through 2M active crystal inverter to supply the primary winding.
3, it is the first generation of mobile phone wireless charging, the technology is mature, but can only be single-to-single short-range charging (qi standard, within 1cm, within 5 watts), and can not be similar to WiFi single-to-multiple charging.
1, Qi is the world's first standardization organization to promote Wireless charging technology - Wireless Power Consortium (hereinafter referred to as the alliance) launched the wireless charging standard, with two characteristics of 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.
2, 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. Qi Wireless charging standard by the Wireless charging Alliance (Wireless Power Consortium, referred to as WPC) initiated the development, is currently widely recognized in the world withoutLine charging standard.
3, Qi is the world's first to promote Wireless charging technology standardization organization - Wireless charging Alliance (Wireless Power Consortium, referred to as WPC) launched the "wireless charging" standard, with convenience and versatility of the two characteristics. Different brands of products, as long as there is a Qi logo, can be charged with Qi wireless charger.
4, wireless charging, that is, through electromagnetic induction to transfer electrical energy to the device that needs to be charged, so as to achieve a way of charging. The traditional way of charging requires the use of a wire connectionStandby and power supply, and wireless charging can eliminate the wire, eliminate the cumbersome plug and unplug process, more convenient and fast. In addition, wireless charging can also protect equipment and human safety, reduce the risk of electrification, and provide people with a more comfortable and safe life experience.
5, Qi means "in Asian philosophy stands for" _ "- an invisible energy. Qi is the world's first standardization organization to promote wireless charging technology - Wireless charging Alliance (WirelessPowerConsortium, hereinafter referred to as the "Alliance") launched the "wireless charging" standard, with convenience and universalTwo characteristics of sex. First of all, different brands of products, as long as there is a Qi logo, can be charged with Qi wireless charger.
6, Qi wireless charging, simply put, is a kind of electromagnetic induction principle, through the Qi standard for mobile phones, cameras and other small equipment wireless charging technology. This standard is formulated by the world-renowned organization Wireless Power Alliance (WPC), and has been widely accepted and applied by the industry, including Apple, Samsung, Nokia and other global giants have adopted Qi as the wireless charging standard for their devices.
