2, according to the current technology of air separation charging, the application scenario is only mobile phones. With air charging is different, as long as the effective range of air charging, handThe air is transferred and then converted into current to be transmitted to the intelligent terminal. After charging the battery and passing through the power management module, the DC output is converted into high-frequency alternating current through the 2M active crystal oscillator inverter to supply the primary winding. By coupling the energy of the two inductors, the electrical output of the secondary coil is changed into direct current through the receiving conversion circuit to charge the battery. 2, from the theory, wireless charging technology is safe and harmless to the human body, the resonance principle of wireless charging is magnetic field resonance, only in the same frequency resonance between the coil transmission, and other devices can not accept the band, in addition, the magnetic field used by wireless charging technology is itself to peopleIt's harmless.
3, wireless charging mainly uses electromagnetic induction, magnetic field resonance, radio waves, electric field coupling and other principles. Wireless charging Because the charger and the electrical device transmit energy by magnetic field, the two are not connected by wires, so the charger and the electrical device can be no conductive contact exposed.
4, electromagnetic induction. A certain frequency of alternating current in the primary coil generates a certain current in the secondary coil through electromagnetic induction, thereby transferring energy from the transmission end to the receiving end.
2, the current mainstream wireless charging standards have three airfuelWireless charging solution : Power Matters Alliance (PMA) standard: The Power Matters Alliance standard is initiated by Duracell Powermat, which is a joint venture between P&G and Powermat, a wireless charging technology company, and has a relatively outstanding comprehensive strength. In addition, Powermat is a supporting member of the Alliance for Wireless Power (A4WP) standard.
Wireless mobile power working principle: is the use of electromagnetic induction, that is, when the current through the coil to generate a magnetic field, the formation of voltage, after the voltage will generate current for charging. You can charge your phone even without a cable. Wireless charging is a device or device with a built-in battery that obtains power through wireless induction. The technology stems from wireless power delivery.
The principle of wireless charging treasure is to use wireless electromagnetic energy transmission technology to charge mobile devices. This technology enables the mobile device to be charged by establishing a radio magnetic field between the wireless charger and the mobile device, which transmits electrical energy from the wireless charger to the mobile device. Wireless charging bank usually consists of two parts: wireless charger and wireless charging module.
The principle of wireless charging mobile power: magnetic energy is converted into electrical energy, according to the principle of induction cooker because wireless charging requires a sending and receiving end, so wireless charging mobile power is installed on the basis of conventional mobile power, and the charging mobile phone is to support wireless charging, with wireless charging receiving coil.
TuringPhoneHubblePhone7iairfuel wireless charging solution , It is the latest model of the Turing mobile phone airfuel wireless charging scheme airfuel wireless charging scheme , which uses the airfuel wireless charging scheme Hubble technology, with government-grade encryption and security features and artificial intelligence enhancements, fully demonstrates the efforts of the Turing mobile phone brand to incorporate high-tech elements. In summary, the brand name of the Turing phone is not "Turing", but "Turing". The choice of this name happens to be closely combined with the brand publicity direction and product characteristics, which can be described as very clever.
According to the domestic mobile communication standards, Turing mobile phones support GSM, TD-SCDMA, CDMA2000, WCDMA and TD-LTE and other mobile network bands, which can basically cover all provinces in ChinaNetwork services for administrative areas. Among these supported mobile network bands, GSM and CDMA2000 are the most common 2G network bands, mainly used for voice communication and SMS services.
For example, its built-in MagiChat communication tool can carry out end-to-end encrypted chat to protect users' information security. At the same time, the Turing mobile phone also has a built-in domestic browser, which can easily browse Chinese websites. In addition, the Turing phone also provides an open developer platform for developers to develop and optimize mobile applications.
1, the principle of wireless charging of mobile phones in the general sense is the process of converting electrical energy into magnetic field, magnetic field is transmitted through the air, and magnetic field is converted into electrical energy. The principle of wireless charging is somewhat similar to the understanding of the transformer in the popular sense, the transformer magnetic field coupling circuit is a magnetic conductor, the wireless charging magnetic field coupling circuit is air, and the magnetic medium is different. Wireless charging in the industry generally has four major technologies: magnetic induction technology, magnetic resonance technology, microwave technology and electric field coupling technology.
2, in popular terms, electromagnetic induction wireless charging and general transformers, household induction cooker working principle is similar, and Apple's use of wireless charging scheme is also belongs to this category. As for magnetic resonance wireless charging is relatively more complex, by transmitting electromagnetic waves to transmit electrical energy, and the transmission distance is far greater than electromagnetic induction wireless charging, magnetic resonance technology has improved by an order of magnitude, but the charging efficiency has dropped significantly from 70%-75% of magnetic induction to less than 50%. 3, from the theory, wireless charging technology is safe and harmless to the human body, and the resonance principle used by wireless charging is magnetic fieldResonance is only transmitted between coils that resonate at the same frequency, and other devices cannot accept the band, in addition, the magnetic field used by wireless charging technology is itself harmless to the human body.
4, First of all, we need to understand the principle of wireless charging. Wireless charging technology uses the principle of electromagnetic induction to establish a magnetic field between the transmitting end and the receiving end, so that electric energy can be transferred between the two ends, so as to achieve the process of charging. At this stage, most wireless charging devices use the Qi standard, which mainly specifies the power and distance of wireless charging, and some big brands such as Apple and threeThis criterion is also used for magnitudes.
5, First of all, we have to understand what is wireless charging. Wireless charging technology (Wireless charging technology; Wireless charge technology is derived from radio energy transmission technology. From the basic principle, it can be divided into three kinds of electromagnetic induction primary coil with a certain frequency of alternating current, which generates a certain current in the secondary coil through electromagnetic induction, so as to transfer energy from the transmission end to the receiving end.
