1, first of all, to understand the working principle of wireless charging. The wireless charging system mainly consists of two parts: the transmitter (usually placed on the charging pad or charging dock) and the receiver (installed inside the phone). The transmitter generates a magnetic field, which the receiver converts into electricity via induction to charge the phone's battery. To add wireless charging to a regular phone, the most critical thing is to install a wireless charging receiver.
2, you can buy a wireless charging receiver, attach it to the back of the phoneOr insert the charging port of the mobile phone, the advantage of this method is that the cost is low, there is no need to replace the mobile phone or disassemble the internal phone, the disadvantage is that it may affect the beauty and feel of the mobile phone, as well as increase the wear and tear of the charging port.
3, self-made wireless charger 1: external module installation steps Stick the module in the place from the MicroUSB interface comparison. Step Connect the MicroUSB or Lightning port on the module to the phone. Steps If there is double-sided tape on the receiver, you can glue it directly to the back of the phone. If it doesn't come with it, you have to figure it out yourself. Step to mostThe mobile phone is placed on a charger or wireless charging base that supports the Qi standard, and wireless charging can be achieved.
Wireless charging methods include electromagnetic induction, magnetic resonance, electric field coupling and radio wave transmission, etc. Wireless charging of mobile phones mostly uses the principle of electromagnetic induction. Electromagnetic induction wireless charging, when the current of the power supply through the coil (wireless charger's power supply coil) will generate a magnetic field, other unenergized coil (mobile phone side of the electric coil) close to the magnetic field will generate current, charging the mobile phone.
Connect the phone's standard charger and data cable to the wireless charger, and then the phonePut it in the center position of the wireless charger base, you can realize wireless charging, and the indicator light will have a breathing effect, and it will be extinguished after 5 seconds, plug and play, convenient and quick.
The reason why mobile phones can achieve wireless charging is to rely on electromagnetic induction, radio waves, magnetic field resonance and electric field coupling. Its different ways, based on the relevant principles are not the same, the details are as follows. This kind of wireless charging method is relatively popular in the current market, and the principle of wireless charging depends on the effective conversion of magnetic energy and electric energy.
The use of electromagnetic induction principle for charging equipment, the principle is similar to the transformer, through the transmitter and receiver end set coils, the transmitter coil under the action of power to send electromagnetic signals, the receiver coil receives electromagnetic signals and convert electromagnetic signals into current, so as to achieve the purpose of wireless charging.
Wireless charging, also known as inductive charging, non-contact inductive charging, from wireless power transmission technology, is the use of near-field induction, that is, inductive coupling, by the power supply equipment (charger) to transmit energy to the device that uses electricityThe device uses the received energy to charge the battery and at the same time for its own operation.
Wireless charging system mainly adopts 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, using 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 a bridge connecting the charging base station and equipment.
Wireless charging is also called inductive charging,Non-contact inductive charging How to make wireless charging , from wireless power transmission technology, is the use of near-field induction, that is, inductive coupling, by the power supply device (charger) to transmit energy to the electricity How to make wireless charging device, The device uses the energy received from How to make a wireless charge to charge the battery and at the same time for its own operation.
The principle of wireless charging technology is "magnetic electricity", which is simply through the charging device and mobile phone equipmentTwo "magnetic devices" mounted on each other induce an electric 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.
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 supply power to the system directly. Go byAfter the power management module output direct current through 2M active crystal inverter converted into high frequency alternating current supply primary winding.
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. High-power wireless charging usually uses resonance (most electric vehicles are charged this way) to transfer energy from the power supply device (charger) to the electrical device. The device uses the received energy to charge the battery and at the same time provide energy for the battery's own operation.
