Mobile phone wireless charging refers to the meaning that the charger and the electrical device can be connected to the phone without wires.
Wireless charging means providing electrical power to electronic devices wirelessly. Wireless charging is a modern technology that does not require a traditional physical cable connection to charge electronic devices. The basic principle is to use electromagnetic induction or radio waves to transmit energy. This technology uses a charging dock or charger to wirelessly sense the device to achieve electricityThe transmission of energy. There are many ways to implement the specific principles and technologies of wireless charging.
Wireless charging, 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.
Wireless charging refers to the technology of providing electrical energy to electronic devices through wireless technology. Wireless charging mainly relies on wireless induction technology to achieve energy transmission. With the rapid development of electronic technology, the traditionalThe wired charging method can not meet the needs of users gradually due to its problems such as inconvenient insertion and removal, limiting the location of equipment, etc. The emergence of wireless charging technology solves these problems.
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.

Professor Xu Shuyuan of the Department of Electronic Engineering of the City University of Hong Kong has successfully developed a "wireless battery charging platform" in the early years, which can place several electronic products on a charging platform without external wires and automatically charge through low-frequency electromagnetic fields, and the charging time is no different from that of traditional chargers. However, this technology still requires the product to contact the charger, which mainly uses the principle of near-field electromagnetic coupling. 3, To answer this question, we need to start from the development of wireless charging and its principle. History of wireless chargingIn the 1830s, Michael Faraday discovered that changes in the surrounding magnetic field would create an electric current in a wire. In the 1890s, Nikola Tesla, an assistant to Edison's spectral radiation research project, proposed the idea of wireless power transmission.

Amway water purifiers started using Fulton's wireless charging technology 10 years ago.
In general, noneLine charging and on-board charging box are two effective ways to solve the long-distance charging problem of pure electric vehicles. Wireless charging is favored for its safety and convenience, while on-board charging boxes provide reliable support in emergency situations. However, for an efficient and fast charging experience, charging piles are still the solution of choice.
At present, wireless charging in addition to the application of mobile phones, in other industries are also gradually increasing, the most typical is electric vehicles. The gasoline consumed by automobiles is not only a non-renewable energy source, but also produces greater pollution in the process of use and has a bad impact on the environment. The emergence of electric vehicles is a turning point for electricityThe power plant also has an impact on the environment, but it is far better than the ubiquitous exhaust gas.

The iPhone series models have been equipped with Apple Silicon chips since the iPhone 4.
5, at present, Apple has no open rights to third parties, so it does not support the addition of cards in addition to bus cards and bank cards, but ios15 can add its wireless charging history his card.
Solar charging At present, solar charging is a common way of charging. Many car dolls are powered by solar energyHead. Therefore, this technology is expected to be applied to car driving in the future to ensure that the car can be charged when driving under a certain amount of light. However, if you encounter bad weather conditions, it may hinder the charging and driving problems of the vehicle.
From a technical point of view, running while charging can be achieved, there are two ways, one is wireless charging highway, the second is solar charging. The technology for wireless charging transmission is called "magnetic resonance coupling". The two copper coils are adjusted to the same frequency to form a resonance, and one is placed every few kilometers.In simple terms, DWPT technology is buried in the asphalt roadThe transmitter of wire and wireless charging can be charged while moving when the vehicle equipped with wireless charging receiving device is driving on the highway.

But these are small-scale trials.
1. Wireless charging technology was invented by Nikola Tesla. In 1890, the physicist and electrical engineer NikolaTesla had already done experiments with wireless power transmission. The International System of Units for magnetic induction is also named after him. 2, 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. The 1890sNikola Tesla, an assistant in Edison's spectral radiation research project, proposed the idea of wireless power transmission. The first patent application for wireless charging technology can be traced back to 1891, proposed by Nikola Tesla. The core of this technology is to establish wireless energy transmission between the charger and the device through the principle of electromagnetic induction or magnetic resonance, instead of directly powering the device through physical lines. Tesla's wireless charging research laid the foundation for later wireless charging technology.
