Wireless charging technology evolution (a future development trend of wireless charging)

What principles are used to make wireless charging systems?

Research on the principle of wireless charging technologyDating back to the 1830s, scientist Michael Faraday first discovered the principle of electromagnetic induction, which is that changes in the surrounding magnetic field will create an electric current in a wire. In the 1890s, Nikola Tesla, an assistant to Edison's spectral radiant energy research project and a future scientist, confirmed the possibility of wireless transmission of radio waves and filed the first patent.

If you are using a vivo mobile phone, wireless charging is also known as inductive charging or non-contact inductive charging, based on the principle of electromagnetic induction, the device that needs to be charged will be wireless after being energizedThe charger can charge on contact.

The reason why mobile phones can achieve wireless charging is to rely on electromagnetic induction, radio waves, magnetic field resonance and electric field coupling. Its different ways, based on the relevant principles are not the same, the details are as follows. This kind of wireless charging method is relatively popular in the current market, and the principle of wireless charging depends on the effective conversion of magnetic energy and electric energy.

Technical principle: Qi wireless charging mainly uses the principle of electromagnetic induction. When there is a magnetic field between the transmitting end and the receiving end of the charger, the magnetic field will generate an induced current fromTo provide the power needed to charge the device. This technology does not rely on physical contact, so it avoids the trouble of plugging and unplugging cables. Application: Qi wireless charging technology is widely used in daily life.

Now the wireless charging is more common magnetic resonance charging mode. 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".

Wireless charging is also known as senseShould be charged or non-contact inductive charging, based on the principle of electromagnetic induction, 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.

To answer this question, we need to start from the development of wireless charging and its principle. In the 1830s, Michael Faraday discovered that changes in the surrounding magnetic field would create an electric current in the wire. In the 1890s, Nikola Tesla, an assistant to Edison's spectral radiation research project, proposed the idea of wireless power transmission.

However, wireless charging is destined to represent the future. As communication methods from wired phones to mobile phones, fixed networks to wireless Wi-Fi, the performance of wireless may not be as strong and stable as wired connections, but in terms of practicality wireless technology will eventually become mainstream. The future wireless charging technology will be more and more efficient and convenientYes.

What technologies does wireless charging use?

Science and technology. Wireless charging technology (Wirelesschargingtechnology; Wirelesschargetechnology, derived from wireless power delivery technology.

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 chargingElectricity: When the current of the power supply passes through the coil (the power supply coil of the wireless charger), a magnetic field will be generated, and other unenergized coils (the electric coil of the mobile phone) will be near the magnetic field, and the current will be generated to charge the mobile phone.

Technology that uses magnets to charge devices. Wireless charging technology, derived from wireless power transmission technology, uses magnetic resonance to transmit charge in the air between the charger and the device, and the coil and capacitor form resonance between the charger and the device to achieve efficient transmission of electric energy technology.
