6, QI technology, the use of electromagnetic induction principle, contact charging; Wireless charging technology, magnetic resonance principle, no contact,Range charging. (Since the energy is transmitted between the charger and the electrical device by inductive coupling, the two are not connected by wires, so the charger and the electrical device can be exposed without conducting contacts.) Prior to this, wireless charging technology has been only related to "small" mobile devices such as smartphones and small-size tablets.
1, the mobile phone space charging technology is the potential of installing the transmitter coil on the wireless charging baseDemand , install the receiving coil on the back of the mobile phone. When the mobile phone is charged near the charging seat, the transmitting coil will generate an alternating magnetic field due to the access of alternating current. The change in the potential demand of the magnetic field wireless charging will generate an induced current in the receiving coil, which transfers energy from the transmitting end to the receiving end, and finally completes the charging process. 2, in simple terms, the wireless charger is actually a charging mode that relies on the energy of electromagnetic waves to convert electromagnetic waves into electrical energy.
3, wireless charging technology there is still a lot of room for development, electricityMagnetic induction is only one of them, and there is also a theoretical technology such as magnetic resonance supported by air charging, interested in their own understanding. Finally, if you are using wireless charging, be sure not to put the bus card with a chip, bank card, etc. near the wireless charger, which may be degaussed and bring unnecessary trouble.
4, the realization of air separation charging technology requires a close cooperation between the mobile phone and the charging device. First, the charging device needs to accurately identify the location and charging needs of the phone to adjust the frequency and strength of the magnetic field. Second, the phone needs an efficient receiver coil and charge management chip inside,To ensure that the magnetic field energy can be quickly received and stably converted into electrical energy.
5, mobile phone space charging device is a wireless charging and emission program that meets the requirements of ROHS, using low-frequency magnetic resonance wireless charging technology, making the charging distance greatly increased, the furthest charging distance can reach 35mm, easily realize the convenience brought by wireless. The application of this solution can realize the wireless charging transmitter products placed on the desktop (non-metal or magnetic conductive material) below, mobile phones, laptops and other Qi standard equipment placed on the desktop, can be wireless charging/power supply.
6, finish charging the phoneA surname The wireless charger connected to the power supply excludes the patented technology to control the size of the current and magnetic flux parameters, which is essentially a pile of wires that are regularly tangled together. During its access to 220V household AC, a closed loop will be formed, and the magnetic field will be generated in the closed loop due to the action of AC, and the magnetic flux of the magnetic field will change accordingly, which can be understood as the magnetic force will change.
Analysis of the production and sales of new energy vehicles New energy passenger vehicles are growing strongly, the impulse of the transition period is expected to be new energy passenger vehicles, and the sales of new energy vehicles are maintaining a rapid growth rate. In 2018, the sales volume of new energy vehicles was 12.73 million, with a year-on-year growth rate of 646%. The main reason for the leading sales of new energy vehicles potential demand for wireless charging is the strong growth in sales of new energy passenger vehicles, especially the plug-in hybrid model sales exceeded expectations.

"Five years of rapid development, the future prospects are promising, but there may be a fluctuation, new energy vehicles will move forward in the fluctuation." Xu Changming said. The following is the speech of Mr. Xu Changming, Deputy Director of the State Information Center: Distinguished guests, good morning! I am very pleased to share with you my views on the development trend of new energy vehicles.
Wireless charging Power consumption when not charging. All electrical equipment as long as the power is turned on will consume power, including the display of some LED indicators, which need power to support.
When wireless charging is not used, there will be a discharge phenomenon. At present, most of the mobile phones on the market have a power management system, which will automatically stop the input current after full charge, and there will be no overcharge problem. Secondly, today's chargers have a complete automatic stop function. Before charging the mobile phone, plug the power supply first and then plug the mobile phone. If you plug the mobile phone first, the charging moment will produce a relatively large voltage pulse.It may cause harm to mobile phones.
Wireless charger does not charge the case, generally he may be standby, almost 1 watt is less than, you do not have to worry about this, almost 0.3 watts or so, so the power is very low, equivalent to a power adapter on the standby side.
Mobile phone wireless charging using inductive coupling technology to implement charging, wireless charger has a primary coil, mobile phone charging receiver has a secondary coil. After the wireless charger is powered on, the primary coil is in a power consumption state regardless of whether the mobile phone is placed on the wireless charger. Therefore, do not putCell phones, wireless chargers are also power-hungry. Hello, I'm glad to solve the trouble for you don't worry, this does not have any impact, it is the same as the mobile phone charger, as long as the charger is not charged from the power end can be unplugged, of course, even if it is not unplugged it will not consume power, you just take the wireless magnetic force line from the Apple Watch can be removed. In addition, the Apple Watch goes from zero to full charge in about five hours.
