2, Zikko Apple wireless charger compared with the common wireless charger on the market, it has the advantages of high 10W fast charging, multi-coil without aligning fixed position, all-round charging and so on. Equipped with high 10W dual coil wireless transmission power, compared to the common single coil, it does not need to be aligned to a fixed position when charging. It has three modes of horizontal and vertical placement, no matter it is horizontal, horizontal and vertical placement, it can truly achieve all-round charging.
3, HUAWEI: reliable quality, moderate price, support a variety of equipment charging, speedAlthough not fast charge, but wireless convenient, suitable for summer use. BELKIN: Stylish design, responsive, fine workmanship, fast charging, and non-slip protection. PISEN: high appearance level, light and portable, C port design is easy to use, and has good support for Samsung mobile phone wireless fast charging.
4, Belkin (Belkin) is a well-known electronic accessories manufacturer, its car wireless charger is known for high quality and stable performance. Belkin's car chargers are generally simple in design, easy to install, and have overcharge, overmild short circuit protectionProtection and other safety features. In addition, they tend to provide fast charging speeds, ensuring that the user's phone is fully charged while on the road.
1, first of all wireless charging is not a new technology, as early as the last century has long been the basis of wireless charging and concept, have seen the movie top duel? That lightning generator in there, that's how wireless charging works. And long ago, wireless charging has been used in some early PHS mobile phones and electric toothbrushes, so it is not absentIt has been used in practice.
2, wireless charging is not a castle in the air, but through a special power supply method. It cleverly uses the propagation characteristics of electromagnetic waves, without the need for physical power lines, to convert the energy of electromagnetic waves into electricity, and then provide lasting power support for our electronic devices. Each waveform is like the heartbeat of a wireless charger, recording the subtle process of energy transmission and conversion.
3, small whale cloud wireless charging equipment uses low-frequency magnetic resonance technology, the maximum effective charging distance of up to 3CM. Place the wireless charging transmitter under the desktop when in use (the desktop must not be metal)Material or magnetic conductive material), when the mobile phone with wireless function is placed on the desktop sticker, wireless charging can be carried out.
4, in recent years, more and more smart phones began to be equipped with wireless charging function, such as iPhone Xs, Samsung S Xiaomi MIX Huawei MATE20 and so on, many small partners are no stranger to this function. At present, there are four main wireless charging methods: electromagnetic induction charging, magnetic field resonance charging, radio wave charging, and electric field coupling. The technical solutions of various charging methods are also different.
5, new energy vehicle charging technology solutionAnalysis: In the pursuit of high-efficiency charging methods, fast charging technology stands out. Among them, DC fast charging (DC fast charging) can rapidly fill the battery within tens of minutes with the characteristics of high voltage and high current, and its charging speed continues to improve with the iteration of technology. AC Fast charging (AC fast charging) technology enables a fast and convenient charging experience with the right equipment.
6, fast charging: At present, fast charging technology still has limitations. However, in the last year, fast-charging stations have appeared. In general, it can be full of about 80% power in ten minutes. It is expected that the technology willThe co-powered car is equipped with a wireless charging system.
Second, the power of wireless charging is low and the cost is high. The current passenger car wireless charging power is up to 11kW, the efficiency is lower than wired charging, the equipment cost is more significant, a 3kW wireless charging system price of more than 10,000, and the same efficiency of AC slow charging pile only more than 1,000. The high cost and low efficiency make the popularization of wireless charging technology face serious challenges. Moreover, the electromagnetic wave radiation problem caused by wireless charging cannot be ignored.
And recently Apple has continuously begun to poach Tesla's vehicle designers, a great deal of serious productionThe ambition of the car.
Sun Li: The two existing companies are Zhejiang Wan 'an and Anjie Wireless, which belong to the first-class suppliers of automotive electronic parts. After so many years of development in wired charging, the division of labor has been clear, and car manufacturers do not need to do charging piles. However, wireless charging is still in the early stage, and manufacturers of wireless charging products still need to make a set of related products, otherwise consumers can not find the corresponding wireless charging pile.
2, first wireless chargingElectricity is not a new technology, as early as the last century has long been the basis of wireless charging with the concept of Taiwan wireless charging price , have seen the movie top duel? That lightning generator in there, that's how wireless charging works. Long ago, wireless charging has been used in some early PHS mobile phones and electric toothbrushes, so it is not without practical applications. 3. It signed a multimillion-dollar contract with Toyota to develop battery-powered car chargers and announced a deal with Med, a Taiwanese electronics makeriatek partnered to develop products that charge mobile devices. The advantages of wireless charging cars are very obvious, such as wireless charging of electric vehicles without exposed connectors, so that you can completely avoid leakage, electricity and other safety hazards.
4, the amount of radiation of the mobile phone when charging and not charging is very small, and it will not affect people. Because mobile phone radiation comes from the transmitter and receiver, after the shutdown, they do not work, so there is no mobile phone radiation. However, it itself is radioactive, because all objects in nature, as long as there is a temperature will produce electromagnetic radiation, but very small,It's negligible.
Wireless charging PCB, different functions, the required components are different. The required components are: resistor, capacitor, resonant capacitor, resonant coil, MOS tube, control chip, protocol chip.
Xiaomi 10 The new flagship machine Xiaomi 10, has up to 30W wireless flash charge function, minutes to let the power misoZooming, and there is a 10W fast wireless backcharge, that is, you can charge the Mi 10 for other phones that need to be charged.
iPhone7Plus is a dual 12 megapixel camera, the blur effect is natural, you can see the preview of the background blur in the photo interface. AppleAirPods battery life of 5 hours, with headphones automatically play music, beam microphone effect is better, double click the headset to open Siri, charging case support 24 hours of battery life, the link is very simple, just open it to let the iPhone automatically recognize. Using W1 chip,There are sensors, batteries, all in the little headset body.
