Today to share the knowledge of wireless charging technology, which will also explain the wireless charging demonstration, if you happen to solve the problem you are now facing, don't forget to pay attention to the site, start now!
< ul>Electric vehicles can be charged without relying on charging cables, and non-contact power transmission can be achieved through electromagnetic induction, electric magnetic resonance, radio frequency and other means. There is no exposed connector for wireless charging of electric vehicles, which can adapt to a variety of harsh environments and weather, and avoid safety hazards such as leakage and electricity running. Easy to use, the vehicle only needs to park to a fixed location to charge, and no supervision is required. The power supply and transformer are hidden underground to save space.
Automobile wireless charging technology is a non-contact way to transmit electric energy through electromagnetic induction, electromagnetic resonance, frequency and other charging methods, without the use of exposed connectionsConnector, thereby avoiding leakage, running and other safety hazards, making charging more convenient. At present, this technology has only been applied in some mid-to-high configuration models.
Automobile wireless charging technology is an electric vehicle charging method that does not rely on charging cables, and realizes non-contact power transmission through electromagnetic induction, electromagnetic resonance, radio frequency and other ways to avoid safety hazards such as leakage and electricity running. Compared with traditional wired charging, it has the advantages of convenient use and no supervision, but the power is smaller and the transmission efficiency is slightly lower. Electric vehicle wireless charging mainly has two ways: electromagnetic induction and magnetic resonance.
Electric vehicle wireless charging technology is what, detailed introduction electric vehicle wireless charging technology - the basic principle of radio wave - similar to the early use of ore radio, mainly composed of microwave transmitter and microwave receiving device, receiving circuit, can be captured from the wallThe bouncing radio wave energy adjusts with the load while maintaining a stable DC voltage.
Automobile wireless charging technology reveals the wireless charging technology of electric vehicles, that is, through electromagnetic induction, magnetic resonance or radio frequency and other ways to achieve non-contact power transmission without charging cables. This technology avoids the safety hazards such as leakage and running caused by traditional wired charging, and at the same time, the wireless charging system does not need exposed connectors, so it is more adaptable to various harsh environmental and weather conditions.
1, the principle of electric field coupled wireless charging is to transmit electrical energy through the induced electric field generated by the coupling of two sets of asymmetric dipoles in the vertical direction. Suitable for short distance charging, high conversion efficiency, the position can not be fixed; However, the disadvantage is that the equipment is large and the power is small. Therefore, at present, among the four wireless charging methods, electromagnetic induction wireless charging scheme is the most mature and most widely used in business.
2, the wireless charger is actually the use of electromagnetic induction principle for charging equipment, similar to a transformer, there is a coil at both ends of the sending and receiving ends, and the sending end coil is connectedThe wire power supply generates an electromagnetic signal, and the receiving coil senses the electromagnetic signal at the transmitting end to generate current to the electrical equipment. As shown in the figure below, current flowing through the coil creates a magnetic field. The proximity of other unenergized coils to a magnetic field generates an electric current.
3, electromagnetic induction primary coil of a certain frequency of alternating current, through electromagnetic induction in the secondary coil to produce a certain current, so as to transfer energy from the transmission end to the receiving end.
4, first you need to have an iPhone that supports unlimited charging, such as iPhone X, iPhone8 plus, etcAfter you need to buy wireless chargers from formal channels, it is recommended to go to APPLE official dealer to buy. Then power on the wireless charger, make sure there are no magnetic objects around before connecting the power. Then place it in a flat place to prevent the phone from slipping off it.
5, first of all, you need to have an iPhone that supports wireless charging, such as iPhoneX, iPhone8, iphone8 Plus and so on. Then you need to buy wireless chargers from formal channels and recommend them to Apple's official resellers. Before connecting the power supply, please first power on the wireless charger and ensureRecognize non-magnetic objects around you. Then put it in a flat place to prevent the phone from slipping off.
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 charger usage: the mobile phone standard charger and data cable connected to the wireless charger, and then the mobile phone upright/horizontalPlaced in the center position of the wireless charger base, wireless charging can be achieved, the indicator light will have a breathing effect, 5 seconds after the extinguish, plug and play, convenient and quick.
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. As shown below.
is similarThe primary winding. By coupling the energy of the two inductors, the electrical output of the secondary coil is changed into direct current through the receiving conversion circuit to charge the battery.
Wireless charging source is installed inside a electromagnetic coil, after opening the power switch, the electromagnetic coil will convert the power supply battery into a large amount of magnetic energy, and then use a reverse coil (international standard brick QI coil), receive this large amount of magnetic energy, convert it into electrical energy, through a metal output head, into our equipment reserve battery. Wireless charging Because electromagnetic transmission only needs to be transmitted in space, no medium is required, so wireless charging can be carried out.
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 cord, using the latest wireless charging technology, through the use of the magnetic field generated between the coils, the magic transmission of electrical energy, inductive coupling technology will become a bridge connecting the charging base station and equipment.
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 to contact the device that needs to be charged with the wireless charging baseCharge up.
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.
The principle of wireless charging technology is "magnetic electricity", simply put, through the charging device and the mobile phone device installed on the two "magnetic equipment" mutual induction and formation of current. At present, products supporting wireless charging have appeared in mobile phones, electric vehicles, smart furniture and other fields. Among them, in the mobile phone industry, the "Qi standard" is the mostCommon, in the packaging of many mobile phones and wireless chargers are often marked with Qi labels.
