2, magnetic wireless charging: This is a magnetic way to achieve mobile phone wireless charging technology. A magnetic charging case or charging case is required. After the charging case or charging case is installed on the mobile phone, the mobile phone can be placed on the charging base supporting magnetic charging, and the mobile phone and charging base can be connected through magnetic adsorption, and wireless charging can be carried out.
3, ** Get a MagSafe charger ** : First, make sure you have a MagSafe charger for the iPhone 14, which is magneticA power bank.
The difference between wireless charging bank and magnetic charging bank mainly lies in their charging method and scope of application. To put it simply, wireless charging treasure uses wireless charging technology, which can provide charging services for devices that support wireless charging; The magnetic charging bank is connected to the device through magnetic adsorption to provide wired or wireless charging for the device.
Magnetic charging treasure has high charging efficiency and high cost performance. Wireless charging bank is more convenient to use, but the charging conversion efficiency is relatively low.
A number of third-party magnetic charging banks, generally support 15W and above Qi protocolWireless charging, only 5W when charging the iPhone. Therefore, the charging power of the magnetic charging treasure is far less than that of the wired one, but there are many more scenarios for it to charge. When walking, users can stick the two devices in a piece, put them in a pocket, put them in a bag to charge, which is difficult to do with traditional wired charging banks because of their larger size.
Principle of electric field coupled wireless chargingIt transmits electrical energy through the induced electric field generated by the coupling of two sets of asymmetric dipoles in the vertical direction. Suitable for short distance charging, high conversion efficiency, the position can not be fixed; However, the disadvantage is that the equipment is large and the power is small. Therefore, at present, among the four wireless charging methods, electromagnetic induction wireless charging scheme is the most mature and most widely used in business.
The basic principle of wireless charging is to convert the current into a magnetic field, which 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 direct currentSystem power supply. 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.
Wireless charging technology is a special way of power supply, it does not need the power line, relying on the propagation of electromagnetic waves, the electromagnetic wave energy into electricity, and finally achieve wireless charging. Low-power wireless charging often uses electromagnetic induction, such as the Qi method of charging mobile phones, and ZTE's electric vehicle wireless charging uses induction mode.
Wireless charging system mainly adopts the principle of electromagnetic induction. Wireless charger refers to the need to connect to the traditional charging power cordThe charger on the charging terminal device uses the latest wireless charging technology, through the use of the magnetic field generated between the coils, the magic transmission of electrical energy, inductive coupling technology will become the bridge connecting the charging base station and the device.
Wireless charging technology is derived from radio energy transmission technology, can be divided into low-power wireless charging and high-power wireless charging two ways, its principle is through near-field induction, the wireless charging device will be transmitted by the energy to the charging terminal device, the terminal device will receive the energy into electricity stored in the battery of the device. Low-power wireless charging often uses electromagnetic induction, such as charging mobile phonesQi mode.
Wireless charging is based on the principle of electromagnetic induction, similar to transformer operation, through the transmitter and receiver coil design! --. The transmitting coil releases electromagnetic signals under electric drive, and the receiving coil captures these signals and converts them into current to achieve contactless power transmission. Electromagnetic waves, composed of electric and magnetic fields, can travel through space and are the key to wireless charging energy transfer.
