2, secondly, wireless charging technology wants to be truly popular, and it also has high requirements for accurate positioning and intelligence of vehicles. Only when the vehicle is precisely parked in the charging space can the ground system establish a channel with the vehicle's on-board system and achieve charging. In the case of precise positioning, the same footprint, the number of electric vehicles using wireless charging compared with the traditional charging pile charging will be greatly increased, greatly improving the space utilization and charging efficiency.
3, small power wireless chargingElectromagnetic induction is often used, such as the Qi method of charging mobile phones, but ZTE's electric vehicle wireless charging method uses induction. High-power wireless charging High-power wireless charging usually adopts a resonant mode (most electric vehicle charging in this way) by the power supply device (charger) to transmit energy to the electric device, the device uses the received energy to charge the battery, and at the same time for its own operation.
4, compared with the traditional wired charging method, wireless charging with no charger connection, voltage stability, anti-surge and other advantages, has become an important development direction of electric vehicle charging. exceptIn addition to the advantages of convenience, safety, reliability and small footprint, it also has the following six advantages: Wireless charging of electric vehicles can improve information and intelligence and reduce labor costs.
5. The race to build a universal wireless charging technology is in full swing. New and exciting advances in wireless charging technology and products continue to emerge - some companies are focused on one technology, while others support multiple technologies. But the lack of interoperability between the various technologies is still a big problem, because there is no unified wireless charging standard. The idea of wireless power transmission has been around for years.
1, Today, this technology is gradually entering and changing people's lives. As the world's pioneer in wireless charging, Fulton Innovation has been developing and producing wireless charging devices for 12 years, and the current best-selling Amway eSpring water purifier uses its original eCoupled integrated wireless technology. Amway water purifiers started using Fulton's wireless charging technology 10 years ago.
2, this clean waterThe reason for the application of wireless technology is safe, reliable, simple and convenient. Safe and reliable: the patented technology of radio energy transmission can realize the wireless connection between the ultraviolet lamp and the power supply, which is safe and anti-leakage, and this patent has been applied to the wireless charging function by Tesla, Apple and other high-tech enterprises. Simple and convenient: Turn on the faucet while activating the sensor, instantly activate the UV lamp sterilization technology.
3, the world's first wireless charging technology standardization organization - wireless charging Alliance was introduced into China, and was supported by the Ministry of Information Industry. Alliance members include many well-known companies, such as Energizer, Samsung, LG Electronics,Nokia, such as Amway Water purifiers, adopted Fulton's wireless charging technology as early as 2000.
4, today recommend a wireless charging treasure that I use myself is still good, South Carolina POWER-3 wireless charging treasure because I have been using South Carolina POW-2 charging treasure before, with more than a year, with their own iPhone EXR wireless charging, in fact, the experience is still good, and support 18w wired fast charge, Although wireless is only 5w, but for Apple, regardless of whether it is wired or wireless, it is already a good experience.
5, wireless charging technologyIt was invented by Nikola Tesla. In 1890, the physicist and electrical engineer NikolaTesla had already done experiments with wireless power transmission. The International System of Units for magnetic induction is also named after him.
1, Tesla acquired the German WIFERION, the wireless charging technology used in the modified Model 3,The logic behind this is electromagnetic induction wireless charging. At present, the modified Tesla Model 3 can achieve a maximum of 12KW wireless charging power, the fastest one hour to make up 80 kilometers, full may take about 6 hours.
2. For example, the auto recharge of the Tesla model after the FSD arrives at the destination; Unmanned buses, express vehicles, etc., can also be completely unmanned management; Or you do not have time to find a charging pile for your car, you can send the vehicle to find its own wireless charging pile "foraging"; Wireless charging can also solve the problem that many vehicles do not share charging plugs, just like mobile phonesSimilarly, cars, SUVs, trucks and other different types of different brands of vehicles can use the same charging plate.
3. First of all, Tesla's wireless charging technology uses the principle of electromagnetic induction. The technology transmits energy through special electromagnetic fields, allowing Tesla cars to charge themselves when parked. This technology is not only efficient, but can also greatly reduce charging time. Secondly, the wireless charging technology of Tesla cars also has the characteristics of intelligence. 4. According to media reports, Tesla recently launched a $300 "wireless charging platform" that can simultaneouslyCharge up to 3 devices. This wireless charging pad can provide up to 15 watts of charging power for each device that supports the Qi wireless charging protocol, including iPhone, Android or AirPods headphones. According to Tesla's official website, the charging pad has been opened for pre-sale and will begin shipping in February 2023.
1, according to relevant data, Apple's research and development expenses in 2019From the trend of the past few years, Apple's spending on research and development has only increased, and it also exceeded 100 billion yuan in 2018. Such large-scale R&D investment does produce results, and most of the improvement is on fundamental issues, hardly for gimmicks and marketing.
2, the failure of Apple's 5G chip research and development means that if Apple wants to continue research, it will invest a lot of money, and if it does not use other chips temporarily, it may lose users.
3, in the previous article research and development costs over 100 billion, Apple really did notIs there innovation? I shared the unique hardware and highlights on the iPhone, which mentioned "more than 600nit bright screen, and ultra-low screen reflectivity", iPhone 7 uses a brighter screen and lower reflectivity, the screen brightness is 625 nits, but after turning on the automatic brightness adjustment, The peak brightness of the iPhone 7 can reach 705 nits. If calculated according to the patent fee of 5 US dollars per unit, the annual patent income is as high as 3 billion US dollars, equivalent to more than 20 billion yuan. As a mobile phone manufacturerSamsung and Apple account for almost half of patent revenues. Apple, in particular, has not yet been able to develop its own 5G baseband. Of course, behind the success, are huge investment and long-term persistence. In 2020, Huawei has more than 100,000 people engaged in research and development, accounting for 53% of the total. 5, natural resources Needless to say, if your home has a mine, nature is the business of making money, others can not rob, imitate can not. Huawei uses 10% of its annual revenue for research and development, resulting in revenue of more than $100 billion, which is the third company in the world to exceed $100 billion after Apple and SamsungRevenue of the company. Huawei's core competence is technology research and development.
