1, no harm to mobile phones. Wireless charger uses the latest wireless charging technology, by using the alternating magnetic field generated between the coils, the transmission of electrical energy, inductive coupling technology will become a bridge connecting the charging base station and equipment.
2, for the human body: wireless charging technology is harmless to the human body. The resonance principle used by wireless charging is magnetic field resonance, which is transmitted only between coils resonating at the same frequencyHis device cannot accept the waveband, and the magnetic field used by wireless charging technology is itself harmless to the human body. 3, 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 itself is harmless to the human body.
4, because of the realization of long-distance high-power wireless magnetoelectric conversion, so the energy consumption of the equipment is high. As the distance and power of wireless charging devices increase, the loss of idle work will be greater. Wireless charging technology equipment itself is the realization of secondary energy conversion, that is, the network voltage down (or directly) into direct current after a higher frequency of switching control AC conversion output.
5, there is no difference between the two charging methods for mobile phone batteries. Wireless charging introduction: Wireless charging is completely harmless to the human body, there will be no radiation and the like. It can reduce the number of plugs and prolongs the service life of the mobile phone interface. There are protective Settings so you don't have to worry about the phone exploding for a long time. It is best not to take a very thick protective shell when charging, otherwise high temperature may occur when charging.
strong wireless charging of the mobile phone, and the current working frequency of wireless charging is below 1M strong wireless charging , so it will not affect the signal of the mobile phone.
2, wireless charging hurt mobile phone strong wireless charging ? Wireless charger under normal circumstances will not harm the mobile phone strong wireless charging , wireless charging now the working frequency is below 1M, so the letter to the mobile phoneIt won't make a difference. At present, most mobile phones on the market are in line with the strong wireless charging QI wireless charging standard, with a built-in wireless receiver, it has a rated voltage and current, so the wireless charger has no effect on the mobile phone.
3, the relevant standards for wireless charging have not yet been introduced, and according to the specification documents of the wireless charging Alliance, the working frequency of wireless charging products is set in the range of 50HZ 60HZ, theoretically its electromagnetic radiation level and ordinary small appliances are equivalent, and this standard is lower than the International Non-ionizing Radiation Protection Commission (I)The CNIRP has issued electromagnetic field exposure limits for products exposed to the public, which have been approved by expert committees in more than 35 countries.
4, wireless charger under normal conditions of use will not cause damage to the phone. Today's wireless charging usually operates at frequencies below 1MHz, so it does not interfere with the phone's signal. Most mobile phones already comply with the QI wireless charging standard, have built-in wireless receivers, and have specified voltage and current limits, so the use of wireless chargers will not have a negative impact on the phone.
5, because wireless charging now workThe frequency is made below 1M, so the signal of the mobile phone will not be affected. On the contrary, wireless chargers not only reduce the use of data cables, but also make charging methods more free and safer. It is basically the same as wired charging, but the rate is lower, but the wireless charger still has a high energy conversion rate, which saves energy consumption more.
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. Input terminal when the system worksThe AC mains is converted into direct current through the full bridge rectifier circuit, or the 24V DC terminal is used to supply power directly to the system. 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 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 coils (mobile phone side of the electric coil) close to the magnetic field willIt generates electricity to charge the phone.
The principle of wireless charging: electromagnetic induction. The charging base and the mobile phone terminal have built-in coils respectively. When the two are close, the generating coil generates a certain current in the mobile phone receiving coil based on a certain frequency of alternating current through electromagnetic induction, thereby transferring the point energy from the originating end to the receiving end, and then starting to supply power to the mobile phone from the charging seat. Magnetic resonance.
Wireless charging principle is mainly electromagnetic induction and wireless electromagnetic wave technology. The principle of electromagnetic induction is the basis of wireless charging. When a magnetic field is generated between a charger and a mobile device, it doesIt generates electromagnetic induction. The alternating current generated at the charger end will create eddy currents in the magnetic field, and the receiving coil at the mobile device end will sense this eddy currents. In this way, power is transferred from the charger to the mobile device.
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.
By the power supply device (chargeThe device transmits energy to an electrical device, which uses the received energy to charge the battery and at the same time for its own operation. Since the energy is transmitted by inductive coupling between the charger and the electrical device, there is no wire connection between the two, so the charger and the electrical device can be no conductive contact exposed. Wireless charging mainly uses the principle of electromagnetic induction, magnetic resonance and radio wave technology.
