5, your 13 May not have wireless charging because your device does not support wireless charging technology, or you are not using a compatible wireless charger. Device compatibility: First, has the wireless charger patent expired Qualcomm vice president recently revealed that Qualcomm is developing an innovative wireless charging technology for cars, which is expected to be launched in the next 24 months. This bodes well for the mass adoption we will witness in the futureNew energy vehicles with technology are on the road. However, on the question of price, Qualcomm will leave it to the automaker to give a clear answer. Then to say that the wireless charging used by the passenger car before, the power is not as efficient as the slow charging pile, and the current level can exceed the slow charging efficiency. From this point, wireless charging has been qualified to be loaded into the car. However, the application of wireless charging technology to the field of new energy vehicles seems to be a very worthwhile thing, but the specific research and development process has encountered a number of problems. The Ministry of Industry and Information Technology recently solicited opinions from the community, the main content is the needleThe standard of wireless charging for electric vehicles is regulated. To facilitate the development of the wireless charging industry in the future. Due to the limitation of charging current, the previous fixed charging pile can not be filled immediately in a short time, and the parking will wait for one or two hours, which has a great impact on the user's experience. Now, as soon as the wireless charging standard comes out, there will naturally be manufacturers trying wireless charging schemes. Easy car news recently, according to the sky eye check website displayShanghai NIO Automobile Co., Ltd. published a new patent, the patent application date is April 2020, the publication date is July 2020, the patent name is "wireless charging system and wireless charging method for vehicles". And NIO has applied for a national patent for a wireless charging system for vehicles on April 16 this year. This system mainly includes a charging transmitter, a charging receiver, a first drive device, a second drive device, a control device, and a vehicle acquisition device. The opening method is very simple, just need to find the car network option on the control screen in the car, and then clickClick wireless charging to turn on. Because NIO provides in-car wireless charging services, you can wireless charge mobile phones and other devices, and the charging speed is also very fast, which is very convenient. The wireless charging function needs to be set on the center control screen. Connect one end of the USB mobile phone charging cable of the wireless charging machine to the wireless charger and the other end to the car cigarette port. After the connection is complete, fix the position of the wireless charger to ensure that it will not slip off, and then put the phone on the wireless charger to charge. Size geometry? From this 3D model diagram, Wei brand's brand new GTThe coupe uses four wheels with four corners, but because of the fast back shape, it doesn't look like the rear wheels are so much on the corners. This is also the consistent design of the model under the Great Wall new energy strategy, with a long wheelbase to enhance the interior space of the vehicle and provide more installation space for the battery. Applicability of wireless charging Wireless charging technology is not a universal option for all mobile phones, only mobile phones with wireless charging function can be realized. The power of the charger built into the vehicle varies, and the Qi protocol is generally used to ensure the compatibility of the mobile phone and the charger and avoid battery damage caused by power mismatch. Wireless charging technology comes fromWireless power transmission technology, small power using electromagnetic induction, high power depends on resonant transmission of energy. Wireless charging technology was invented by Nikola Tesla Wireless charging patent expired . In 1890, the "strong" wireless charge patent expired NIO applied for a new patent: wireless charging system and wireless charging method for vehicles
Who invented wireless charging technology
The first patent application for wireless charging technology can be traced back to 1891, by Nikola Tesla. The core of this technology is to power the device directly without having to go through a physical line,Instead, it establishes wireless energy transmission between the charger and the device through the principle of electromagnetic induction or magnetic resonance. Tesla's wireless charging research laid the foundation for later wireless charging technology.
Oh, this invention is indeed an Amway patent! Fulton Innovation, a subsidiary of Amway, launched the world's first wireless charging Tesla car from January 6 to 9, 2011, "2011 International Consumer Electronics Show" was held in Las Vegas, United States. At the exhibition, Fulton Innovation, a subsidiary of Amway Corporation, demonstrated wireless charging technology and launched the world's first wireless carA charging Tesla car.
1, no strong wireless charge patent expired radiation Wireless charge patent expired , no effect on the human body! The main principle is: the way of wireless charging is electromagnetic induction, magnetic resonance, electric field coupling and radio wave transmission, etc. Most of the wireless charging of mobile phones uses the principle of electromagnetic induction.
2, the way of wireless charging has electromagnetic induction, magneticResonance, 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 unenergized coil (mobile phone side of the electric coil) close to the magnetic field will generate current, charging the mobile phone. 3, 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, iThere are five kinds of NPOFi technology and Wi-Po technology. Let's take a look at the principle of wireless charging.
4, the principle is to transmit power by coupling two sets of asymmetric dipoles along the vertical direction of the induced electric field generated. This charging method has a high conversion rate, and the position of the two can also be fixed, but there is a big disadvantage, that is, the volume of the device is larger, and the power is particularly small. The electromagnetic resonance also requires the interaction of the mobile phone and the charging platform, which requires the resonator of the two sides to produce a magnetic field resonance to achieve the conversion of energy.
