Today to share the knowledge of wireless charging scheme classification, which will also explain the wireless charging in several ways, if you happen to solve the problem you are now facing, don't forget to pay attention to the site, start now!
< ul>1, static wireless charging Static wireless charging technology is to charge the car when the electric vehicle stops, according to its characteristics,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.
2, 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 the power supply device (charger) transmits energy to the electrical device, which uses the received energyThe quantity charges the battery and at the same time provides for its own operation.
3, the current wireless charging mode mainly includes three types: electromagnetic induction, magnetic field resonance, radio wave.
4, 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 designed for electricity use by means of electromagnetic fields or electromagnetic waves without being connected by physical wiresThis principle, but the position must be relatively uniform in order to charge efficiently. And there is also coupling radiation problem, electromagnetic wave coupling will not exist a large magnetic field leakage. 2, 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 take a look at the principle of wireless charging.
3, electromagnetic induction charging technology: thisWireless charging technology realizes energy transmission through the principle of electromagnetic induction. A certain distance should be maintained between the charging base and the charging device. Usually, the charging device needs to be placed on the charging base for charging. This technology has high charging efficiency and is suitable for small electronic products such as mobile devices.
4, wireless charging methods include electromagnetic induction, magnetic resonance, electric field coupling and radio wave transmission, 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 transmission coil) will generate a magnetic field, other unenergized coil (wireless charger)Proximity to the magnetic field generates an electric current that charges the phone.
1, wireless charger usage: the mobile phone standard charger and data cable connected to the wireless charger, and then the mobile phone is/horizontally placed in the wireless charger base left and right center position, you can achieve wireless charging, the indicator light will have a breathing effect, 5 seconds after the extinguish, plug and play, convenient and quick.
2, electromagnetic induction The most common wireless charging method is the use of electromagnetic inductionPrinciple, 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, electromagnetic induction. A certain frequency of alternating current in the primary coil generates a certain current in the secondary coil through electromagnetic induction, thereby transferring energy from the transmission end to the receiving end.
