In theory, under the premise that the power level of the router is large enough, we can use Wifi signals to charge mobile devices, but the cost is a bit large. Common home routers have low power, and we may need to increase the power by a thousand times to be enough to charge our mobile devices.
1, QI technology, the use of electromagnetic induction principle, contact charging; Wireless charging technology, magnetic resonance principle, no contact, range charging. (Since the energy is transmitted between the charger and the electrical device by inductive coupling, the two are not connected by wires, so the charger and the electrical device can be exposed without conducting contacts.) Prior to this, wireless charging technology has been only related to "small" mobile devices such as smartphones and small-size tablets.
2, Qi is the world's first to promote wireless charging technologyThe Wireless charging standard launched by the Wireless Power Consortium (hereinafter referred to as the Alliance) has two characteristics: convenience and versatility. First of all, different brands of products, as long as there is a Qi logo, can be charged with Qi wireless charger.
3, Qi wireless charging is a wireless power transmission technology. Qi wireless charging technology is a wireless power transmission technology based on the principle of electromagnetic induction. It allows electronic devices such as smartphones, tablets and wearables to operate without the use of a physical cableCharge it. This technology transmits power through a charging base or charging pad, and simply places the device on the charging base to start charging.
4, Qi wireless charging, in short, is a use of electromagnetic induction principle, through the Qi standard for mobile phones, cameras and other small equipment wireless charging technology. This standard is formulated by the world-renowned organization Wireless Power Alliance (WPC), and has been widely accepted and applied by the industry, including Apple, Samsung, Nokia and other global giants have adopted Qi as the wireless charging standard for their devices.
1, for the human body: wireless charging technology is safe and 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 frequency, and other devices cannot accept the band, in addition, the magnetic field used by wireless charging technology is itself harmless to the human body.
2, there is a little radiation, as long as the person is not between the transmitter and the receiver, the radiation level is very small, and the charging frequency is inconsistent with the main absorption frequency of the human body, the harm can be ignoredPlan.
3, no harm. In theory, wireless charging technology is safe and harmless to the human body, the resonance principle used by wireless charging is magnetic field resonance, which is only transmitted between coils resonating at the same frequency, and other devices cannot accept the band, in addition, the magnetic field used by wireless charging technology is itself harmless to the human body.
4, conclusion: Wireless chargers do produce electromagnetic radiation, although the value is usually small, but should be wary of its possible cumulative effect. With the popularity of wireless charging technology, users are exposed to more and more radiation sources in daily life, such as mobile phones, computers, and WiFI. Long-term accumulation may have health effects. Wireless Charging Technology and controversy With the development of mobile Internet, the rise of wireless charging function has led to a discussion on electromagnetic radiation.
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. Through the power management moduleAfter the output of DC through 2M active crystal inverter converted into high frequency alternating current supply to 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 coil (mobile phone side of the electric coil) close to the magnetic field will generate current, charging the mobile phone. As shown below.
Wireless charging system mainly adopts the principle of electromagnetic induction. Wireless chargerIt refers to the charger connected to the terminal device that needs to be charged without the traditional charging power cord, using the latest wireless charging technology, by using the magnetic field generated between the coils, the magical transmission of electrical energy, inductive coupling technology will become a bridge connecting the charging base station and the device.
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 device (charger) to transmit energy to the power device, the device uses the received energy to charge the battery, and at the same time for its own operation.
Electromagnetic induction type. A certain frequency of alternating current in the primary coil generates a certain current in the secondary coil through electromagnetic induction, thereby transferring energy from the transmission end to the receiving end.
Hello, wireless charging uses the principle of electromagnetic induction, which is equipped with electromagnetic induction coils on the charging device and electromagnetic coils on the charged device.
1, wireless charger is good, convenient, safe and durable; The disadvantages are bondage, high price and low efficiency. Wireless chargerBenefits: Convenient: Wireless charging belongs to one-to-many charging, which solves the problem that the interface is not applicable, and also avoids the phenomenon of poor contact caused by repeated plugging and unplugging of the mobile phone interface, which can better protect the mobile phone interface. 2, wireless charger is good, pros and cons are as follows: Advantages: In order to improve the unity of the mobile phone now most mobile phones are no longer with the headphone hole this design, but many users said that the headphone hole design is not humanized. But with the wireless charger, we can directly put the mobile phone on it, bring headphones to listen to music, but only limited to listening to music, want to play games that is not very presentReal.
3, advantages: The advantage of wireless charger is that we can charge the phone at the same time, no longer need to unplug the data cable. In addition, it can be taken at any time, which is more convenient than charging with a data cable. At the same time, it can provide certain support for the phone, making the phone charge more stable. Disadvantages: One disadvantage of wireless chargers is that the charging speed is relatively slow, and most wireless chargers only support 5W or 5W charging power.
