Today to share with you the mainstream wireless charging scheme what knowledge, which will also explain the wireless charging recommendation, if you happen to solve the problem you are now facing, don't forget to pay attention to the site, now start!
< ul>1, the current wireless charging scheme is nothing more than three. Electromagnetic induction charging is the most widely used scheme so far, which uses the induced magnetic flux generated by the power supply side (charging base) and the receiving side (mobile phone) to carry out power transmission, and this circuit structure is simple and low in cost compared with the other two. But the high efficiency also brings inconvenience, that is, the transmission distance is relativelyShort, affected by placement. 2, wireless charging Wireless charging is mainly through the following three ways: electromagnetic induction, 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.
3, there is also a solution is to use smart grid wireless charging control, electric steamThe wireless charging management authority of the car is handed over, and the wireless charging device is controlled by the smart grid.
4, the current wireless charging method has electromagnetic induction charging, magnetic resonance charging, radio wave charging, electric field coupling charging four, each charging method of the technical scheme is different. Electromagnetic wireless charging uses the induced magnetic flux generated between the inductive magnet on the power supply side and the electric side to convert the magnetic force into electrical energy and then transmit it.
5, Abstract: Wireless charging is a new technology, compared with the traditional data cable charging method, wireless charging can not be transmitted through the cable to charge the mobile phone.What are the ways electricity is implemented?
1, electromagnetic induction type. 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.
2, electromagnetic induction The most common wireless charging method is to use the principle of electromagnetic induction, through the primary and secondary coil induction to generate current, so as to transfer energy from the transmission end to the receiving end. This approach has been achieved by the Wireless Charging Alliance (Wireless? The Power? Consortium; WPC).
4, there are about three transmission methods of wireless charging: electromagnetic induction, radio wave, magnetic resonance. The three methods have their own advantages, among which the radio wave type is not optimistic because of low power, high energy consumption and poor feasibility. fromFrom the perspective of the consumer market, the wireless charging products commonly mentioned generally use electromagnetic induction and magnetic resonance.
5, if the use of vivo mobile phone, you can refer to the following information: wireless charger usage: the mobile phone standard charger and data cable connected to the wireless charger, and then the mobile phone is/horizontal 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 turn off, plug and play, convenient and quick.
6, the mobile phone does not have the function as follows: You can buy a mobile phone case that supports wireless charging and install it on the mobile phoneThe advantage of this method is that it is simple and convenient, and there is no need to replace the phone or disassemble the inside of the phone, but the disadvantage is that it may increase the weight and thickness of the phone, as well as affect the heat dissipation and signal of the phone.
1, Step 1: Buy a wireless charger First, you need to buy a wireless charger. There are many kinds of wireless chargers, and you can choose your own charger according to your needs. Step 2: Connect the wireless chargerPlug the wireless charger into a power outlet, and then connect the charger to your phone. There are two ways to connect: one is connected through the USB interface, and the other is connected through Bluetooth.
2, if you use vivo mobile phone, you can refer to the following information: wireless charging, also known as inductive charging or non-contact inductive charging, based on the principle of electromagnetic induction, it is not necessary 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.
3, prepare a mobile phone that supports wireless charging and a wireless charger. Connect the wireless charger to the power supply and make sure the power supply is working properly. Align the back of the phone with the charging area of the wireless charger to make sure there are no obstructions between the two. Confirm the connection status of the phone and the wireless charger, usually there will be an indicator light or the charging status will be displayed on the phone screen.
1, there are four basic principles of wireless charging, respectively, electromagnetic induction charging, magnetic resonance charging, radio wave charging, electric field coupling charging, the mainstream standards on the market are mainlyQi standard, PMA standard, A4WP standard, iNPOFi technology and Wi-Po technology. Let's take a look at the principle of wireless charging. 2, At present, wireless charging is mainly achieved in four technical ways: magnetic induction technology, magnetic resonance technology, microwave technology and electric field coupling technology. Among them, magnetic induction technology and magnetic resonance technology are the technologies that are basically used in the current mass production products.
3, the market is more mainstream wireless charging technology mainly through three ways, namely electromagnetic induction, radio waves, and resonance, and Qi is the most importantCurrent electromagnetic induction technology. In terms of technology applications, Chinese companies are already at the forefront of the wireless charging industry. It is reported that Qi's application products in China are mainly mobile phones, which is the first stage, and will be applied to different categories or higher power digital products in the future.
1, wireless charger use method: the mobile phone standard charger and data cable connected to the wireless charger, and then put the mobile phone in the wireless charger base left/right center position, you can achieve noLine charging, the indicator light will have a breathing effect, 5 seconds after the extinguish, plug and play, convenient and quick.
2, wireless charger use radio wave transmission, radio wave is not only a kind of electromagnetic wave, its own can also transmit energy, and can penetrate the air, so that wireless power transmission is possible.
3, the first is electric field coupling charging. First, there are two sets of asymmetrical electric dipoles on the phone and charging device. When they are close together, they produce a coupling phenomenon and achieve the transmission of current. The transfer efficiency is good, but there are distance restrictions, and large capacity charging stations are required. The second is magnetic resonance charging, with the above electricityThe field is different. This method generates electrical energy through the resonance of the same frequency magnetic field generated by the resonators at both ends.
4, electromagnetic induction The most common wireless charging method is to use the principle of electromagnetic induction, through the primary and secondary coil induction to generate current, so as to transfer energy from the transmission end to the receiving end. This approach has been achieved by the Wireless Charging Alliance (Wireless? The Power? Consortium; WPC).
5, electromagnetic induction charging, very simple, and high school electromagnetic induction principle is similar to the use of wireless charging charging baseAnd the terminal are respectively built in coils, so that the two close to begin to power from the charging seat to the terminal. Many wireless charging mobile phones are this principle, but the location 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.
6, 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's power supply coil) will generate a magnetic field, other not throughWhen an electric coil (the receiving coil on the phone) is close to the magnetic field, it generates an electric current, which charges the phone.
There are four basic principles of wireless charging, namely, electromagnetic induction charging, magnetic resonance charging, radio wave charging, electric field coupling charging, and the mainstream standards on the market mainly include Qi standard, PMA standard, A4WP standard, iNPOFi technology and Wi-Po technology. Let's take a look at the principle of wireless charging.
In addition, nowStage electric vehicle wireless charging is still facing the problem of high cost and brand compatibility, it is reported that because the upstream and downstream industry chain has not been opened up, it is estimated that the 7kw private wireless charging price is about 20,000 yuan, even if the future wireless charging reaches 1 million sets of orders of magnitude, its cost is still about 30% higher than the traditional charging pile.
pro, etc. Wireless charging technology Because the charger and the electrical device transmit energy by magnetic field, the two are not connected by wires, so the charger and the electrical device can be no conductive contact exposed. The principle of fast charging of mobile phones is to increase the input value of the charging voltage or current. butTo truly realize fast charging of mobile phones, it also needs supporting circuits and hardware. The fast punch technology mainly includes Qualcomm's Quick Charge and Mediatek's Pump Express.
