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. 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.
2, wireless charging system mainly uses the principle of electromagnetic induction. Wireless charger refers to the charger that does not need to be connected to the terminal device that needs to be charged without the traditional charging power cordWith the latest wireless charging technology, the inductive coupling technology will become a bridge connecting the charging base station and the device by using the magnetic field generated between the coils to magically transmit power. 3, wireless charging is 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.
4, generally seen wireless charging, the use of "current magnetic effect" and "electromagnetic sensation.The principle of "should". In 1819, Danish scientist Elster observed that if there is an electric current on a wire, a magnetic field will be generated around it, which can deflect the north finger. Later generations have further found that the wire is encircled into a ring, or even wound into a coil, and the magnetic field generated will be stronger and more concentrated, which is called the "current magnetic effect."
5, there is no strong radiation, no effect on the human body! The main principle is: the way of wireless charging is electromagnetic induction, magnetic resonance, electric field coupling and radio wave transmission, etc. Most of the wireless charging of mobile phones uses the principle of electromagnetic induction.
6. NoneLine charging, also known as inductive charging or non-contact inductive charging, based on the principle of electromagnetic induction, it does not need to transmit electricity to the device like the traditional wired charger, but the device that needs to be charged can be charged by contacting the wireless charging base.
1, please take off the mobile phone protective cover before charging because some mobile phone protective cover is too thick, or the material of the mobile phone protective cover may affect the identification function of the mobile phone wireless charger, it is recommended that you take off the mobile phone protective cover before chargingTry. 4, please check whether there are other items between the mobile phone and the wireless charger. Wireless charging converts electrical energy into magnetic energy for transmission to the phone, and if the magnetic energy is interfered with, charging will be affected.
2, please use the original protective shell, do not use too thick or magnetic insulation material/metal protective shell, these protective shells may affect the charging efficiency or can not be charged, or even overheating to cause the phone can not be charged or damaged. If the above methods do not solve the problem, please back up the mobile phone data in advance, and bring the mobile phone, wireless charger, wired charger set and purchase voucher to vivo customer service center for testing.
3, if your mobile phone cannot use wireless charging, please follow the following steps: Check whether the mobile phone is overheating, it is recommended to charge in a good heat dissipation environment. Check whether the wireless charger indicator light is on normally, and check whether the connection between the charging base, data cable, charger, and power supply is in poor contact. It is recommended to reinsert the wireless charger.
4, please check the connection of the wireless charger Please check whether the connection between the charger, data cable and wireless charger is normal; Whether there are other items between the mobile phone and the wireless charger, such as mobile phone protective cases, metal foreign bodies, etc.; In the phoneWhether the heart is aligned with the center of the wireless charger base; Whether the wireless indicator light is on.
5, if your mobile phone using wireless charging board can not be charged normally, it may be due to a variety of reasons, it is recommended that you try the following operations: Please check whether the mobile phone is placed in the center of the wireless charging board. When there are inclusions between the mobile phone and the wireless charging pad, it may not be able to charge normally. Please check the back of the phone. If the protective phone cover used is too thick may hinder wireless charging, it is recommended to remove the phone cover and try to recharge.
1, two-way wireless charging means that both devices support reverse charging technology, and also have the ability to wireless charging, so that the two devices can charge each other. Reverse charging refers to the mobile phone and other devices that can only receive wireless charging electromagnetic waves, and now can emit electromagnetic waves through the wireless coil to charge other devices that support wireless charging. However, its charging power is small and can only serve as an emergency use.
2, two-way wireless charging is to charge the device wirelessly, and in turn, the device can charge other devices wirelessly. Wireless charging technology is derived from radio energy transmission technology and can be divided intoLow power wireless charging and high power wireless charging two ways. Low-power wireless charging often uses electromagnetic induction, such as the Qi method of charging mobile phones, but ZTE's electric vehicle wireless charging method uses induction.
3, Huawei two-way wireless charging means that both devices support reverse charging technology, and also have the ability to wireless charging, so that the two devices can charge each other. HUAWEI TECHNOLOGIES CO., LTD., founded in 1987, is a private communications technology company that produces and sells communications equipment
