It is based on two core technologies: electromagnetic induction and vibration technology. Now, let's explore the secrets of these two technologies together! Electromagnetic induction technology is the first generation of mobile phone wireless charging on behalf of the transmission of a certain frequency of alternating current through the primary coil, using electromagnetic induction in the secondary coilGenerate current and realize wireless transmission of energy.
The use of magnetic resonance technology principle, junior high school logistics textbooks have some knowledge, simply put: electricity generated magnetic, magnetic generated electricity! The magnetic field generated by the coil is then converted into electricity by the receiving coil, which is why this wireless charging device often carries a thick base and a "phone case".
Electric vehicle wireless charging technology mainly uses the mutual inductance in the law of electromagnetic induction. It is also similar to a transformer, which inputs from the primary coil and then generates an induced current on the secondary coil. It mainly relies on the energy transmission between electricity and electricity to convert electricityIt magnetizes and generates electricity. Wireless charging is simply to charge electrical equipment through electromagnetic fields or electromagnetic waves without being connected by physical wires.
Ultrasonic wireless charging: The effective range is close to 5 meters Advantages: the technology is very safe; The receiver is cheap and small; Can be used for data transmission. Cons: The final product may not live up to expectations in terms of price, power, speed, and safety. The above information is quoted from, hope to be useful to you, hope to adopt.
Wireless charging technology is a new way of charging, which uses a new type of energy transmissionPrinciple, through the primary and secondary coil induction to generate a current, thereby transferring energy from the transmission end to the receiving end. This approach has been achieved by the Wireless Charging Alliance (Wireless? The Power? Consortium; WPC). 3, there are four basic principles of wireless charging, respectively, electromagnetic induction charging, magnetic field resonance charging, radio wave charging, electric field coupling charging, the mainstream standards on the market mainly Qi standard, PMA standard, A4WP standard, iNPOFi technology and Wi-Po technology five. Let's find outLet's talk about the principle of wireless charging.
If you use vivo mobile phone, you can refer to the following information: wireless charging, also known as inductive charging or non-contact inductive charging, based on the principle of electromagnetic induction, you do not need to transfer 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.
Wireless charging, also known as inductive charging, non-contact inductive charging, comes from wireless power transmission technology,It is the use of near-field induction, that is, inductive coupling, by the power supply device (charger) to transmit energy to the electrical device, the device uses the received energy to charge the battery, and at the same time for its own operation.Wireless charging, also known as inductive charging or non-contact inductive charging, based on the principle of electromagnetic induction, it is not necessary 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.

Wireless charging which parts of the introduction to talk about it here, thank you for taking the time to read the content of this site, more about wireless charging there are several standards, wireless charging which parts of the information don't forget to find on this site.
