Wireless fast charging is a combination of wireless charging technology and fast charging technology, and the mainstream models on the market now support wireless fast charging technology. Wireless fast charging mobile phones are Xiaomi Huawei P40, Mate30, Mate30 pro, etc. Wireless charging technology 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.
In general, wireless fast charge is a wireless charging method based on magnetic resonance, electromagnetic induction and other technologies, which eliminates the tedious operation of wired charging and brings users a more convenient and efficient charging experience. Its wide application and continuous technological development indicate that wireless fast charging will become the mainstream way of charging electronic devices in the future.
Wireless fast charge is the use of electromagnetic induction principle, in the hairThe sending and receiving ends each have a coil, the sending end of the coil connected to the wired power supply to generate electromagnetic signals, the receiving end of the coil induction electromagnetic signals to generate current to charge the battery, can be simply understood as a transformer without a magnetic core. Compared with wired, wireless charging has less loss to the battery, and wireless charging technology is more convenient and has lower charging heat.
Wireless fast charge is actually a function, is the short for wireless charging function, but also represents the wireless charger. This charger can not be connected to the socket, very convenient. With a fast charging function, directly do not needTo charge the phone with the data line, the user only needs to put the phone near the wireless charger to charge it directly. The following is a detailed example to introduce this wireless charging method.
In simple terms, the so-called wireless charging is that it can be charged without touching the wire, and the mobile phone that supports wireless charging can be put and charged on the wireless charger. 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.
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, wireless charging methods are electromagnetic induction, magnetic resonance, electric field coupling and radio wave transmission, wireless charging of mobile phones mostly uses the principle of electromagnetic induction. Electromagnetic induction wireless charging, when the power supply of the current through the coil (wireless charger of the power supply coilA magnetic field is generated, and other unenergized coils (the charged coils on the phone) near the magnetic field will generate an electric current to charge the phone.
3, the reason why mobile phones can achieve wireless charging is to rely on electromagnetic induction, radio waves, magnetic resonance and electric field coupling and other ways to achieve. 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.
4. The electric energy transmitting coil is installed in the charging base and connectedThe receiving coil is installed in the electronic device. Resonance This kind of wireless transmission method is similar to the principle of wireless communication, the electromagnetic wave of the resonant loop at the sending end is permeated in the entire space, and the resonant loop at the receiving end is at the specific frequency, so as to achieve the transmission of energy. This transmission mode can obtain higher transmission efficiency when the output power of the receiving end is relatively small.
5, according to the mobile phone wireless charging method and implementation principle, it is generally divided into three categories, magnetic resonance, electromagnetic induction and radio waves. The most used is electromagnetic induction, relative to the other two wireless charging methods, electromagnetic induction technologyElectricity, based on the principle of electromagnetic induction, does not need a transmission cable to transmit electricity to the device like a traditional wired charger, but the device that needs to be charged can be charged by contacting the wireless charging base.
2, if the use is vivo mobile phone, wireless charging is also known as inductive charging or non-contact inductive charging, based on the principle of electromagnetic induction, the device that needs to be charged can be charged by contacting the wireless charger after being energized.
3. Connect the phone's standard charger and data cable to the wireless charger, and then place the phone directly (vertically) or horizontally in the center position of the wireless charger base to achieve itWireless charging, the indicator light will have a breathing effect, 5 seconds after the extinguish, plug and play, convenient and quick.
Connect the standard charger and data cable of the mobile phone to the wireless charger, and then put the mobile phone directly (vertically) or horizontally in the center position of the wireless charger base, you can realize wireless charging, the indicator light will have a breathing effect, 5 seconds later, plug and play, convenient and quick.
Connect the standard charger and data cable of the mobile phone to the wireless charger, and then the mobile phone is upright/horizontalPlaced in the center position of the wireless charger base, wireless charging can be achieved, the indicator light will have a breathing effect, 5 seconds after the extinguish, plug and play, convenient and quick.
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. 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.
Mobile phone can be realWireless charging is achieved by means of electromagnetic induction, radio waves, magnetic 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.
Charge the wireless charger by directly placing the phone screen facing up in the center of the charger or in the position suggested by the manufacturer.
When the coil of the charging board is connected to the power supply, AC is added to the coil belowWhen we put the mobile phone on the charging board, the coil on the back cover of the mobile phone will sense the change of the magnetic field, so that the coil on the back cover of the mobile phone will sense the current, and then the current is converted into direct current to charge our mobile phone battery, so as to achieve wireless charging.
