In daily life in the 21st century, the popularity of electronic devices such as mobile phones, smart wearables and robots has brought convenience, but the traditional way of charging - wired or disposable batteries, not only brings inconvenience to use, but also has a certain impact on the environment.

Flying wire charging is a new typeCharging technology, which transmits electrical energy wirelessly, enables devices to charge without touching the power source. Flying wire charging is a wireless charging technology that transmits electrical energy from the transmitter to the receiver through the principle of electromagnetic induction to achieve device charging. Flying line charging enables the device to be charged without touching the power supply, improving the convenience and flexibility of charging. Application of flying wire charging.

WPC stands for Wireless Power Alliance, also known as wireless charging technology. This technology can transmit electric energy wirelessly to the device to be charged through the principle of electromagnetic induction to achieve wireless charging function. This techniqueIt uses a standard called Qi that allows wireless charging of a variety of electronic devices, including smartphones, laptops, watches, Bluetooth headsets and more.

In this way, the wireless transmission of electrical energy can be achieved. There are two main wireless charging technologies: magnetic coil charging and magnetic resonance charging. Magnetic coil charging is the use of electromagnetic fields to generate current to charge, by adjusting the distance between the transmitter and the receiver to adjust the charging power. Magnetic resonance charging is the use of the principle of magnetic resonance to charge, the transmitter and receiver will produce resonance phenomenon, thereby enhancing the efficiency of electromagnetic energy transmission.

Qi standard wireless charger conversion rate is 75%~85%, and the traditional charger time is about 1/5 longer, but the wireless charger is usually charged in the fragment of time, do not need to drawOut charging time, so timing saves time.

Low efficiency magnetic resonance wireless charging technology conversion efficiency is generally only about 70%, compared with wired charging efficiency is low. Magnetic resonance wireless charging technology requires the establishment of a magnetic field between the transmitting end and the receiving end for energy transmission, but the formation and maintenance of the magnetic field requires a lot of electric energy, and a certain amount of electromagnetic radiation will be generated during the transmission process.

What happens when a phone heats up while charging?

If you are using vivo mobile phone, chargeThere is an energy conversion process, during which a certain amount of heat will be generated, the charging power of the flash charger is larger, and the heat output will be higher when the charging time is shortened, which is a common heating phenomenon. If the ambient temperature is high, such as in summer, it is not conducive to the heat dissipation of the phone, and the heat during charging will be more obvious.

Put the phone in a good heat dissipation environment to charge (such as: indoor, desktop), the environment with poor heat dissipation conditions will lead to slow heat dissipation when charging (such as: sunlight, bed, sofa), so that the temperature rises. Please avoid using your phone while charging. Cell phone will heat up when charging, during useIt will also heat up, and if it is used while charging, it will aggravate the fever phenomenon. You are advised to clear unnecessary applications in the background.

System version: EMUI0 Software version: null Some mobile phones do not support charging while playing, which will cause the mobile phone to be hot when charged. It could be that the charging current is unstable, causing the phone to get hot. There may be a problem with the charging plug or the charging cable. It is recommended to check whether the charging cable is in poor contact or damaged. If damaged, it needs to be replaced in time. The battery has a problem, the battery of the mobile phone has a service life, and it needs to be replaced after a long time of use.

Some mobile phones do notEnough to support charging while playing, so while charging while playing mobile phones will appear hot mobile phone phenomenon. The unstable charging current causes the phone to be hot. If the charging plug or cable of the mobile phone is faulty, it is recommended to check whether the charging plug or cable is damaged or in poor contact. If it is damaged, replace it in time. There is a problem with the battery of the mobile phone. The battery of the mobile phone has a service life and needs to be replaced after a long time of use.

Heat is a common phenomenon when charging mobile phones, especially support fast charging, super fast charging mobile phones, when charging, the current and voltage are larger, so the temperature will be higher than ordinary charging. If you are doingWireless charging, because in the process of wireless transmission there will be energy loss, and then generate a certain amount of heat, there will be a phenomenon of wireless charging heat, this is normal.

Is radio power transmission lossless?

The principle of radio energy is: electrical energy is converted into radio, that is, electromagnetic waves, which are then converted into electrical energy, most of which are wasted electromagnetic waves. The current so-called wireless phone charger, wireless notebook power supply, less line is very convenient, but waste electricity, such as emissionThere is the ability to send 10w power, receive only 1w power is effectively received, and the remaining 9w is not radiation.

And his research focuses on Earth's free solar power systems, which transmit electricity wirelessly from the ionosphere to the surface. The ionosphere is the upper atmosphere, a charged layer of positive and negative ions ionized by the solar wind. He wants to draw electricity straight from here, no electricity at all. Nature's pure natural free solar energy..

Electrical energy can also be transmitted wirelessly. It's just experimental right now. Wireless transmission technology is the use of radio technology to transmit electricityThe technology of force energy is still in the experimental stage. Technically, there is no essential difference between wireless transmission technology and transmit and receive technology used in radio communication. But the former focuses on the transmission of energy, not the information attached to it.

What happens when a wireless charger burns a phone?

1, wireless charging mobile phone hot is a normal phenomenon. In the process of wireless charging, the hot mobile phone is the result of a variety of factors. The following will be from the working principle of wireless charging, energy conversion efficiency, mobile phone heat dissipation designAnd the use of the environment, explain in detail why the mobile phone will be hot when wireless charging. First, the working principle of wireless charging involves electromagnetic induction or magnetic resonance, both of which generate heat.

2, if you are conducting wireless charging, because there will be energy loss in the wireless transmission process, and then produce a certain amount of heat, there will be a phenomenon of wireless charging heat, this is normal.

3, wireless charger mobile phone charging heat is a normal phenomenon, but if charged to hot, we should pay attention to whether there is a problem with product quality. The original wireless charger does not rule out possible faults. Charge separatelyWhen using electricity, pay attention to whether the power of the wireless charger matches the phone. For mobile phones that support wireless charging, just place the phone in the middle of the wireless charger to charge the operation, which is relatively convenient.

Wireless charging is better or wired charging is better

Frequent wireless charging has no effect on the phone battery. Wireless charging and wired charging effect is the same, but the wireless charging time is relatively longer, no impact on the phone. Wireless charging is the use of electromagnetic induction principle, through the coil coupling fromAnd to achieve the transfer of energy.
