The principle of wireless charging is that through near-field induction, the wireless charging device conducts energy to the charging terminal device, and the terminal device converts the received energy into electrical energy and stores it in the battery of the device. The principle of energy conduction is inductive coupling, which ensures that there is no exposed conductive interface. Not only can eliminate the messy transmission line between the equipment, for electric toothbrush and other frequent contactElectronic devices with conductive media such as liquids are also safer.
So now a "closed loop" is formed. Wireless charging power wants to be larger, but the battery will be hot, easy to produce thermal runaway; However, if the wireless charging power is not large, there is no need to get on the car. Unless next, the wireless charging end is connected to the tram's thermal management system, which can be combined with real-time understanding of the state of the electric vehicle battery charging, which must take into account algorithms, communication and other aspects.
The basic principle of wireless charging is to convert the current into a magnetic field, which is transmitted through the air and then converted into a current to be transmitted to the intelligent terminal. System work>The technology is to charge the car when the electric car stops, and depending on its characteristics, it is usually suitable for shopping malls/residential parking lots and other occasions. Radiation-type radio energy transmission technology transmits energy through the far field, mainly including radio wave and laser mode, which is suitable for long-distance wireless transmission, due to its low efficiency/low power characteristics, are not mature.
Wireless charging can be divided into low-power wireless charging and high-power wireless charging two ways, low-power wireless charging often uses electromagnetic induction, such as mobile phone charging. High-power wireless charging often uses magnetic resonance and is powered by the power supply device (chargingThe device transmits energy to an electrical device, which uses the received energy to charge the battery and at the same time for its own operation.
At present, wireless charging methods mainly include three types: electromagnetic induction type, magnetic field resonance type, radio wave type.
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, converts electricity into magnetism, and then induces electricity. Wireless charging simply means that it is not connected through a physical wireIn this case, the electrical equipment is charged by means of electromagnetic fields or electromagnetic waves.
Wireless charging technology is derived from radio energy transmission technology, which can be divided into two ways of low-power wireless charging and high-power wireless charging. 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.

The basic principle of wireless charging is to convert the current into a magnetic field, which is transmitted through the air and then 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.
Wireless charging system is mainly adoptedPrinciple 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.
Hello, wireless charging uses the principle of electromagnetic induction, which is equipped with electromagnetic induction coils on the charging device and electromagnetic coils on the charged device.
Generally seen wireless charging, the use of the "current magnetic effect" and "electromagnetic induction" principle. 1819Danish 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."
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. After the battery is charged, the DC output after the power management module is reversed through the 2M active crystal oscillatorThe primary windings are converted to high frequency alternating current supply. 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.
2, the wireless charging source is installed inside a electromagnetic coil, after the power switch is turned on, the electromagnetic coil converts the power supply battery into a large amount of magnetic energy, and then uses a reverse coil (international standard brick QI coil) to 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, fromAnd you can do wireless charging.
3, 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.
Another solution is to use the smart grid for wireless charging control, hand over the wireless charging management authority of electric vehicles, and control the wireless charging device by the smart grid.
Wireless charging Wireless charging mainly through the following three ways: electromagneticInduction, radio waves, magnetic resonance currently the most common wireless charging solution is: Electromagnetic induction, which generates an electric current through primary and secondary coil induction to transfer energy from the transmission segment to the receiving end, is a solution provided by companies such as Splashpower in the UK, WildCharge and Fulton Innovation in the US.
For pure trams, the most reliable solution now is electromagnetic induction, which is more stable and reliable. Although magnetic resonance can have a higher power distance advantage (a few centimeters to a few meters) than electromagnetic sensing,However, it is difficult to control and technical difficulty, and it is not easy to use it for electric vehicles (which may be the development direction of wireless charging in the future).
