Today to share the knowledge of Huachuang wireless charging program, which will also explain the wireless charging of Huachuang mobile phone, if you happen to solve the problem you are facing now, don't forget to pay attention to the site, start now!
< ul>Connect the charging base Connect the charger to the wireless charging base, and then place the phone or the phone with the wireless charging back case on the wireless charging base. Take off the holster If the phone's holster is too thick or not the original charging holster, it may affect the charging effect, it is recommended to take off the holster and try charging.
Huawei p40 Wireless charging Method Huawei wireless charging only applies to some partsCell phones have this feature. Not all cell phones have this feature. This section describes how to enable and operate Huawei p40 wireless charging. Turn on wireless charging First, tap on [Settings] on the desktop of your phone.
Some high-end mobile phones of Huawei can support wireless charging in addition to super wired fast charging, and wireless chargers need to be purchased separately to use wireless charging. How to use Huawei wireless charger? Connect the charger (the charging tip that came with your phone or was purchased separately) to a power source. Connect the data cable Connect the charger to the wireless charger using the data cable. Place the phone Place the rechargeable area of the phone wirelesslyIn the center of the upper surface of the charger, the phone shows that it is charging.
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.
Prepare the accessories needed for charging, Qi wireless charger, wireless charging receiving coil. With these ready to go, we're ready to operate. Plug in the receiver coil and plug the wireless charging receiver coil into the phone port, just like you normally charge. insertThe problem of wire loss also saves a lot of space.
MOTOROLA built a breakthrough system based on Qi technology that not only makes charging wireless, but also automatically recharges in the background, even in the pocket. However, this technology requires extremely high spatial accuracy, and any object that intervenes will interrupt the charge. To address this challenge, MOTOROLA joined forces with GuRu, an innovative company focused on improving charging efficiency.
Get a mobile phone that supports wireless charging and a wireless charger. Connect the wireless charger to the power supply and make sure the power supply is working properly. tetsutThe back of the machine is aligned with the charging area of the wireless charger to ensure that there are no obstacles between the two. Confirm the connection status of the phone and the wireless charger, usually there will be an indicator light or the charging status will be displayed on the phone screen.
Electromagnetic induction type primary coil a certain frequency of alternating current, through electromagnetic induction in the secondary coil to produce a certain current, so as to transfer energy from the transmission end to the connectionStop it.
One of the self-wound coil is connected in the charging circuit, 555 output pin (third pin) is connected to an output tube (oneself at will, but to the high-frequency power tube) the output tube is linked to the self-wound coil, and the connected two coils are close (about 1 cm or so there is a very sufficient charging current). The efficiency of this circuit is very low, because there is only half a wave peak high frequency so the loss is relatively large, but the principle is quite simple and easy to produce.
Principle: The DC-DC switching power supply is divided into two parts at the high-frequency transformer, and resonant coupling is adopted; Then use RFID technologyData communication and current feedback are performed. In a single-phase bridge rectifier circuit, if there is a filter capacitor, when the load is open, the output voltage (that is, the voltage at both ends of the capacitor) is the peak of the AC input voltage, that is, U output =414*U input, that is, the input voltage of the root 2 times.
1, the basic principle of wireless charging is to convert the current into a magnetic field, which is transmitted through the air and converted into a current to be transmitted to the intelligent terminal. After the battery is charged and passes through the power management module, the DC output is inverted by 2M active crystal oscillatorSwitch to high frequency AC to supply the primary winding. By coupling the energy of the two inductors, the electrical output of the secondary coil is changed into direct current through the receiving conversion circuit to charge the battery.
2, the wireless charging source is installed inside a electromagnetic coil, after the power switch is turned on, the electromagnetic coil converts the power supply battery into a large amount of magnetic energy, and then uses a reverse coil (international standard brick QI coil) to receive this large amount of magnetic energy, convert it into electrical energy, through a metal output head, into our equipment reserve battery. Wireless charging because electromagnetic transmission only needs to be transmitted in space, no medium is required, thusIt's ready for wireless charging.
3, the basic principle of wireless charging is to convert the current into a magnetic field, and the magnetic field 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. 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.
4, wireless charging system mainly uses the principle of electromagnetic induction. The wireless charger refers to the terminal that needs to be charged without the traditional charging power cordThe charger on the standby, 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.
