Today to share with you the wireless charging coil production requirements of what methods of knowledge, which will also explain the wireless charging coil winding technology, 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 production of ring ox core charger coil needs to follow the following steps: Prepare the required materials, including ring ox core, wire, electricityContainers, transformers, switches, etc. According to the design requirements, the ring cow core is punched and cut in order to wind the coil. Determine the number of turns and diameter of the coil in order to calculate the length of the coil.
2, first of all, the magnetic force of NdFeb magnet is not less than one thousand thousand amps per meter, that is, not less than one trillion amps per meter, even if the magnetic circuit is shortened to 0.1 meters of current, there must be at least 1600KA-2400KA current, this current is the current in the coil multiplied by the number of turns of the current. That means you go around 2,400 times and you have to add 1000A of current. Capacitance Pulse capacitors with voltages above 3000V. <3, when designing this magnetization coil, it should be noted that the conductor resistivity should be small, the skeleton permeability should be large, the insulation between the wire skeleton is good, in order to facilitate the winding, it is best to use multi-core flexible wire. In addition, according to the different size of the product, the different magnetization waveform, the design should consider the size of the cross section shape of the wire and the size of the magnetic skeleton, so that the sum of requirements match.
4, the use of 0.2 diameter enamelled wire wound 2400 circles can be energized to generate electromagnetic device. A conductive winding that matches its power is wound around the outside of the iron core. This coil, which carries an electric current, has a magnetic field like a magnetThe induction principle. 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.
At the exhibition, Fulton Innovation, a subsidiary of Amway Corporation, demonstrated wireless charging technology and launched the world's first Tesla car with wireless charging.
No. The wireless charger uses the latest wireless charging technology to transmit electrical energy by using alternating magnetic fields generated between coils, and inductive coupling technology will be the connectionBridge for charging base stations and equipment. Wireless charging technology uses magnetic resonance to transmit electrical energy in the electric and magnetic fields between the charger and the device, and the coil and capacitor form a resonance between the charger and the device.
The company in the pursuit of user experience as a starting point, launched a series of unique green style of excellent products. Products to "UGREEN green United" brand endorsement marketing in most countries and regions, and in Asia, Europe and the United States market won a good reputation.
The front 5 million pixel rear 13 million pixel camera, 6000mAh battery capacity, pre-installed based on Android 1 Deeply customized MIUI10 operating system. The user experience is particularly easy to use, watching TV and watching online classes all use millet tablets.
Magnetic resonance: A new breakthrough in long-distance transmission Magnetic resonance technology takes a different path, which realizes remote transmission through resonator and magnetic field resonance. Especially in the field of electric vehicle charging, efficiency improvement is the focus of research. As shown in Figure 4-2, through the resonance principle, energy is in the transmitter and receiverElectromagnetic waves, the magnetic induction coil on the back of the phone then converts electromagnetic waves into electricity to charge the battery.
MRI. A magneto consists of a large inductor coil with a small capacitor in parallel or in series, and the same resonant frequency is a necessary condition for energy transfer. For example, two coils are used as resonators, the transmitting end vibrates at 10MHz to radiate an electromagnetic field around, and the receiving end needs to vibrate at 10MHz to receive this transmitted energy. Radio waves. The principle is to convert environmental electromagnetic waves into current and transmit current through a circuit.
The core principle of wireless charging is actuallyIt's electromagnetic induction. It's not that complicated. So far, there are two main technologies in the industry, one is the magnetic field induction technology represented by the Qi standard, and the other is the magnetic resonance technology represented by the AiRFuel standard. In principle, magnetic resonance is the better solution, it supports a longer charging distance, and can support multiple devices charging at the same time.
Magnetic field resonance technology: magnetic field resonance wireless charging requires two coils in the energy sending device and the energy receiving device as resonators, composed of large inductors formed by small capacitors in parallel or in series, through the resonance effectThe energy is transmitted, and the two devices need to be adjusted to the same frequency. Compared with electromagnetic induction, magnetic resonance wireless charging has longer transmission distance, higher power supply efficiency, and supports one-to-many power supply.

Question 6: How to do wireless charger Wireless charger is through two coils coupling to the mobile phone, as long as there is coupling current that isThe phone can be charged normally. Question seven: Self-made simple wireless charger transmitter is now common QI solution, you can search a lot on a treasure, find the basic module, and then built into their own products.
ready-made. Charging base, charging back sticker, charging head or charging treasure, charging line, assembled, can be wireless output wireless input, still can be wired charging; Wireless charging waste electricity is certain, slow charging, low efficiency, heat, can not be separated from the base.
1. NoneLine charging, also known as Wireless Power Transmission (WPT), is based on a coupled electromagnetic field as the medium to achieve electrical energy transfer. For electric vehicles, wireless charging is mainly through the power supply coil arranged on the ground and the electric coil at the bottom of the vehicle, and the magnetic resonance generated between the coils replaces the traditional power lines to charge the vehicle. This charging method requires higher spacing between the supply and receiving coils.
2, how the car wireless charging vehicle wireless charging how to use the car wireless charging method is: the car wireless charging fixed in the appropriate position in the cab;Connect one end of the USB data cable of the wireless charger to the car cigarette port and the other end to the wireless charger; After fixing the position of the wireless charger, make sure that it is stable and will not slide, put the phone on and charge it.
3, first of all, click the function on the screen to find Settings 2 Click intelligent Internet to find nfc and wireless charging 3 Click wireless charging, and then click to activate many cars will be equipped with wireless charging function, especially some luxury cars, Mercedes-Benz, BMW, Audi and Cadillac will be equipped with wireless charging system need to note that wireless.
4, first of all, fix the car wireless charger to the cabIn the appropriate position, connect the data cable connector of the wireless charger to the cigarette lighter interface of the car, and connect the other end to the wireless charger. After fixing the wireless charger, ensure that the wireless charger will not slip, and the wireless charger can be used normally.
