As an emerging technology, McDonald's wireless charging brings the convenience of wireless charging to the public. Although at present2 id=' Wireless charging. How far can we go? '> Wireless charging. How far can we go?
Generally about 0.9-2 meters high-power wireless charging transmission distance up to 5 meters wireless charging technology can be divided into low-power wireless charging and high-power wireless charging two ways. Small power wireless charging often uses electromagnetic induction wireless charging point distance , such as the Qi method of mobile phone charging wireless charging point distance , but ZTE's electric vehicle wireless charging method uses induction.
The core magnetic resonance medium and long distance wireless charging developed by Spurotin can successfully achieve wireless charging within one meter.
Currently known reports, the farthest distance is 10 meters, using electromagnetic wave technology. The existing wireless charging technology uses magnetic field, electromagnetic wave, laser, ultrasonic and other energy transfer media. The 10-meter technology mentioned above, which uses electromagnetic waves as a medium, remains in the laboratory stage. At present, the commercial technology on the market is mainly magnetic field as the medium, which is divided into magnetic induction and magnetic resonance 2 technologies.
Wireless charging distance phone and charger can not leaveMore than 10cm, the closer the effect, the better. Wireless charging technology has always been only related to "small" mobile devices such as smartphones and small-size tablets. However, A4WP (" Wireless Charging Alliance "), one of the three major wireless charging camps, recently announced that its technical standards have been upgraded, and the charging power supported has increased to 50 watts, which means that high-power devices such as laptops and tablets can also achieve wireless charging.
The distance of wireless chargers produced by different manufacturers will be different, generally speaking, effective charging can be achieved within 2 to 3 meters.
can do infinity, because it is itself beneficialUse electromagnetic waves. Wherever the electromagnetic wave can go, there is electricity where it is received. It's just a matter of cost. It would probably cost hundreds of millions of dollars to build a device like this. Or hundreds of thousands. But it works in theory. If it's wireless charging. Now the best thing is to put the phone on the launch pad, so that it is easy to control. Because distance plays an important role in the power of wireless charging.
1, mobile phones that support wireless charging are: Huawei Mate 40E Pro,Huawei P50 Pro, Huawei Mate 40E, Huawei Mate 40 Pro, Huawei Mate 30 Pro, Huawei Mate 20 Pro, Huawei P40 Pro, etc.
2. Huawei mobile phones have wireless charging function, but not all mobile phones support wireless charging, only some mobile phones support wireless charging, and the charging base of wireless charging needs to be purchased by oneself. If your mobile phone does not have wireless charging function, you can go to the official website to check whether your mobile phone supports wireless charging. Huawei mobile phone wireless charging function refers to the use of wireless electromagnetic wavesCharging without the need for wires.
3. Huawei mobile phone wireless charging function. You can turn on the wireless reverse charging switch under the battery to enable the wireless charging function of Huawei mobile phone. Tools/materials: Huawei Mate20Pro, Android setup software. Start by tapping the "Settings" option on your phone's desktop. Then in the Settings page that opens, click on the "Battery" option. Finally, in the battery page, open the "wireless reverse charging switch".
4. The wireless charging function of Huawei mobile phones is generally built-in. Users only need to perform the following steps to set itCheck compatibility: Ensure that your Huawei mobile phone supports wireless charging. Only Huawei mobile phones with the wireless charging function can be charged wirelessly. Adjust Settings: Go to your phone's Settings menu and look for wireless charging or similar options in System and Update or battery options.
There will be attenuation of wireless charging voltage. This is because wireless charging is only a transitional technology, because the magnetic field decays quickly in the air, and the distance of the wireless charging technology of today's mobile phones is generally very small and generally effectiveThe charging distance is only 3-8 mm. Taking into account the thickness of the mobile phone protective cover, mobile phone charging is basically close to the charger in order to effectively carry out wireless charging. This limitation doomed this wireless charging technology is only a transitional state.
Low efficiency: energy storage and transmission efficiency is not as good as real contact. Slow charging speed: Due to low efficiency, the charging speed is slow at the same input power. Although wireless charging can be unplugged, the distance between the phone and the charger is very small. However, the electromagnetic energy loss is still not small, and the power received by the general mobile phone is about 75% of the power sent by the charger. It is well known that the attenuation of mobile phone batteries is gradually increased according to the number of charging cycles, research shows that the number of wireless charging battery cycles is much greater than wired charging, about 5 times faster than wired charging, which will lead to wireless charging mobile phone batteries decay faster, shorter service life.
Reduce loss When using wireless charging, you only need to connect the wireless charging board to the power supply, and then place the device that supports wireless charging on the wireless charging board. Although wireless charging still needs to be connected to the power supply, it can reduce the use of data lines and avoid a large number of data linesLoss and waste, relatively speaking, is a relatively environmentally friendly way to charge.
The owner has abandoned the traditional data cable. Charging also makes the car seem more high-end. If there is no wireless charging on the car, but you want to use it, then you can install this function on the car, generally need to go to the 4S shop or regular auto repair shop for installation, the price is about 1000 to 2000, mainly according to the model to determine the price.
Interface durability is better: Because wireless charging does not require frequent plugging and unplugging of the charging cable, the data interface wear of the phone will be greatly reduced. Also, wireless chargingThe coil is not exposed to the air, which can also reduce the oxidative corrosion of the charging unit. Disadvantages: Although wireless charging has many advantages, there are also some disadvantages in actual use.
Mobile phone space charging technology is to install the transmitter coil wireless charging point distance on the wireless charging base, and install the receiving coil wireless charging point distance on the back of the mobile phone.When the mobile phone is charged near the charging seat wireless charging point distance , the transmitting coil will generate an alternating magnetic field due to access to AC. The change in the magnetic field wireless charging point distance generates an induced current in the receiving coil, which transfers energy from the transmitting end to the receiving end, and finally completes the charging process.
Wireless space charging technology is a wireless charging technology that enables electronic devices to achieve wireless charging technology through electromagnetic induction, magnetic resonance and other principles without plugging wires. The principle is to emit electricity through the transmitter (charger)The magnetic wave signal is then received by the receiving end (electronic device) to receive the electromagnetic wave, and the received energy is converted to achieve charging.
Electromagnetic induction: The working principle is: install the transmitter coil on the wireless charging base, install the receiving coil on the back of the mobile phone, when the mobile phone is near the charging seat to charge, the transmitter coil will generate alternating magnetic field due to access to AC. The change in the magnetic field generates an induced current in the receiving coil, which transfers energy from the transmitting end to the receiving end, and finally completes the charging process.
The principle of wireless charging: electromagnetic induction. A charging dock and a mobile terminal are built inCoil, when the two are close, the coil based on a certain frequency of alternating current through electromagnetic induction in the mobile phone receiving coil to generate a certain current, so as to transfer the point energy from the source to the receiving end, and then start from the charging seat to the mobile phone for power supply. Magnetic resonance.
