Wireless charging principle (wireless charging principle)

Wireless charging principle and transmission mode

1, wireless charging is also known as inductive charging or non-contact inductive charging, based on the principle of electromagnetic induction, it is not necessary to transmit electricity to the device like the traditional wired charger, but to connect the device that needs to be charged with the wireless charging baseCharge by touch.

2, 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.

3, wireless charging methods include 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's supply coil) willA magnetic field is generated, and when other unenergized coils (the charged coils on the phone) are close to the magnetic field, an electric current is generated to charge the phone. As shown below.

4, also similar to a transformer, input from the primary coil, and then generate induced current on the secondary coil. It mainly relies on the energy transmission between electricity and electricity, converts electricity into magnetism, and then induces electricity. Wireless charging is simply to charge electrical equipment through electromagnetic fields or electromagnetic waves without being connected by physical wires. At present, there are three main methods: electromagnetic induction, magnetic resonance and radio wave.

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 by using the magnetic field generated between the coilsIn order to transfer power, inductive coupling technology will become a bridge connecting charging base stations and equipment.

3, wireless charging methods include 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 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. As shown below.

4, generally seen wireless charging, the use of "current magnetic effect.And the principle of "electromagnetic induction". In 1819, Danish scientist Elster observed that if there is an electric current on a wire, a magnetic field will be generated around it, which can deflect the north finger. Later generations have further found that the wire is encircled into a ring, or even wound into a coil, and the magnetic field generated will be stronger and more concentrated, which is called the "current magnetic effect."

5, the principle of wireless charging technology is "magnetic electricity", simply put, through the charging device and the mobile phone device installed on the two "magnetic equipment" mutual induction and formation of current. At present, wireless charging is supported in mobile phones, electric vehicles, smart furniture and other fieldsThe product of electricity. 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.

6, the principle of wireless charging is that through near-field induction, the wireless charging device conducts energy to the charging terminal device, and the terminal device converts the received energy into electrical energy and stores it in the battery of the device. The principle of energy conduction is inductive coupling, which ensures that there is no exposed conductive interface. It can not only eliminate messy transmission lines between devices, but also be safer for electronic devices such as electric toothbrushes that are often in contact with conductive media such as liquids.

What is wireless charging?

1, wireless charging is also known as inductive charging or non-contact inductive charging, based on the principle of electromagnetic induction, it is not necessary to transmit electricity to the device like the traditional wired charger, but the device that needs to be charged can be charged by contacting the wireless charging base.

2, mobile phone wireless charging refers to the charger and the electrical device between the two can charge the mobile phone without wire connection.

3, wireless charging, also known as inductive charging, non-contact inductive charging, is the use of closeField induction, or inductive coupling, is the transfer of energy by the power supply device (charger) to the device that uses electricity. If the distance between the charger and the electrical device is far, it is necessary to use resonant inductive coupling design.

How does wireless charging work for mobile phones?

1, wireless charging, also known as inductive charging or non-contact inductive charging Wireless charging principle , based on the principle of electromagnetic induction, do not need to be like the traditional wired charger transmission cable to transmit electricity to the device, but will need to chargeThe device can be charged by touching the wireless charging base.

At present, products supporting wireless charging have appeared in mobile phones, electric vehicles, smart furniture and other fields.

4, the basic principle: The use of electromagnetic induction, that is, the primary coil of a certain frequency of alternating current, through electromagnetic induction in the secondary coil to produce a certain current, so as to transfer the energy from the transmission end to the receiving end.
