2, prepare the accessories needed for charging, Qi wireless charger, wireless charging receiving coil. Plug the wireless charging receiver coil into the phone port and plug in the receiver coil. After the wireless charging receiving coil is placed on the back of the phone, it will not affect the use of the phone. Then the charging head is plugged into the wall socket, and the other end of the data cable is linked to Qi wireless charging emissionEquipment.
3, first of all, you need to ensure that the mobile phone is supporting wireless charging, because wireless charging requires the hardware support of the mobile phone built-in wireless induction coil. Connect the wireless charging board with the data cable to the charger, the general mobile phone charger can be used, the charging board will have a light prompt after the general connection, and then put the mobile phone on the charging board.
4, Apple xr wireless charging coil in the center of the back of the phone. Place the iPhone XR on the wireless charger with the display facing up. In order for the mobile phone to receive the wireless charging signal stably and accurately, the central bit of the mobile phone needs to be changedWhy the fever? '> Why does the magnet between the wireless charging coil and the receiving coil heat up? First, the working principle of wireless charging involves electromagnetic induction or magnetic resonance, both of which generate heat. When an electromagnetic field is formed between the coil of the charger and the receiving coil on the back of the phone, energy is transferred between the two. In this process, part of the energy will be converted into heat, causing the phone and charger to become hot. Secondly, energy conversion efficiency is also a factor leading to heating.
It is normal for coils to heat up. You need to increase the diameter of the copper wire. There's too much current in there.
According to theory, this should be affected, because the principle of wireless charging is to generate a magnetic field through the power supply, and then the induction coil in the mobile phone to convert the magnetic into electricity, if there is a magnet sheet, it may complete the magnet sheet heat, may cause problems. In fact, the phone itself has magnets inside, to achieve some functions, such as wireless charging, will be affected by strong magnets.
Because the main structure of the wireless charger is a coil, the main structure of the device that your phone receives wireless charging is also a coil, the coil overcurrent, heat is very normal, the general temperature rise is not too highTopic.
- When the magnetic field emitted by the transmitting coil passes through the battery, the metal in the battery will generate an induced current, which is usually called "eddy current". This eddy current will generate a magnetic field in the opposite direction of the magnetic field generated by the transmitting coil, which will offset the magnetic field formed by the transmitting coil and make the induced voltage received by the receiving coil decrease; And that vortex turns into heat (which is how induction cookers work), making the phone's battery very hot.
Selection of heating components. qi standard wireless charging is originally the use of electromagnetic induction, generate current, promote the circuit work. In hairThe emitting end, through the inductor (coil), the resonant capacitor and the control chip together to form an LC oscillation circuit, by oscillating in the frequency range of 110-205kHz, the receiving end will generate current due to the changing magnetic field, so as to charge the mobile phone.
The working principle of the wireless charger: The electromagnetic induction principle is used, and the energy coupling through the coil is realized. When the system is working, the input end will convert the AC mains into direct current through the full bridge rectifier circuit, or useThe 24V DC end supplies 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 coil (mobile phone side of the electric coil) close to the magnetic field will generate current, charging the mobile phone.
Wireless chargingElectricity is also known as inductive charging, non-contact inductive charging, derived 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.
Wireless charging principle is mainly electromagnetic induction and wireless electromagnetic wave technology. The principle of electromagnetic induction is the basis of wireless charging. Electromagnetic induction occurs when a magnetic field is generated between a charger and a mobile device. The alternating current generated at the charger end will form eddy currents in the magnetic field and moveThe receiving coil on the moving device senses this eddy current. In this way, power is transferred from the charger to the mobile device.
