1, Tesla's wireless transmission is not practical reasons: First of all, Tesla's so-called global wireless transmission technology is not electromagnetic waves, and pollution-free, but before the realization of communism, it is impossible, because it is global wireless transmission. Second, the technology was available back then, but Tesla didn't have what it neededThe funds did not materialize until after his death. 2. Tesla is an unreliable genius, which is one of the reasons why he is admired by the folk, who generally prefer a man who can blow a whistle to an old pedant.
3, there is no accuracy, Tesla has never tried to wireless transmission over long distances. So far, Tesla's vision hasn't materialized. The reason should not be a matter of scientific principles, but from the technical and cost aspects. Tesla's wireless transmission technology has problems with electromagnetic radiation and efficiency. The electromagnetic wave will spread outward and its efficiency will rapidly decline as it followsInverse square law of distance.
4, also is not, special occasions wireless transmission technology will still have its incomparable advantages.
5, Tesla's wireless power transmission technology has electromagnetic radiation and efficiency problems, electromagnetic waves will spread out, its efficiency will rapidly decline, because it follows the inverse square law of distance. If you want to build a megawatt wireless power transmitter, you have to keep pumping 1 million watts of power into it, even if the power side only wants to receive 10 watts from it.
1, Tesla acquired the German WIFERION, in the modified version of the Model 3 application of wireless charging technology, behind the logic 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. 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.
3, wireless charger refers to the charger that does not need to be connected to the terminal device that needs to be charged, using the latest wireless charging technology, wireless charging technology obtained 20 patents in 2007, a variety of devices can use a charging base station, mobile phones, MP3 players, power tools and other power suppliesWired charging of the adapter will no longer exist. 4, the charging process of Tesla takes about 12 hours, but when using a home charger, the voltage may drop due to the peak of the transformer load, which affects the charging speed. To increase efficiency, it is recommended to install a special wall-mounted charger, which will reduce the charging time to about 9 hours. The optional dual built-in charger can further shorten the charging cycle, and it only takes about 4 hours to full charge.
5, Qi wireless charging standard is the most widely used technology on the market. It is based on the principle of electromagnetic induction, converting electrical energy into magnetic fieldsAnd then convert the magnetic field into electricity to charge the device. Although this technology is relatively mature and safe, there are certain heating problems, so users should avoid buying low-cost or inferior products when choosing wireless chargers. One of the main disadvantages of wireless charging is the relatively slow charging speed.
6. Although Tesla's idea was feasible, neither financial resources nor social status allowed it, so it did not succeed. On June 7, 2007, the journal Science published the results of a research team at the Massachusetts Institute of Technology, who successfully realized wireless charging. In 2017, wireless charging mobile phones went on sale, withIs the mobile phone wireless charging function of the car used by multiple people?
1, more and more mobile phones have begun to standard wireless charging function, the car slowly must also be equipped with the corresponding function to the owner. Now the new models have slowly begun to be equipped with mobile phone wireless charging device, the front installation is not equipped with can choose to modify the nine-speed special car special car wireless charging device.
2, the wireless charging standard can charge all phones that support Qi, and can support multiple products charging at the same time. This charging can be achieved by simply placing the phone on a table. In addition, as wireless technology standards mature,This device will be installed in all public places, users can be at home, office, street and even train wireless charging, very convenient.
3, for the car wireless charging, generally speaking, most mobile phones are compatible, as long as the mobile phone has wireless charging function, no matter which brand or model of mobile phone, you can charge on the wireless charging panel in the car, the operation is very convenient. For example, high-end models such as BYD Han and NiO ET7 have built-in wireless charging functions, and owners do not need to worry about mobile phone type restrictions.
4, in general, the car can really supportWireless mobile phone charging, and this trend is increasingly popular. The development of wireless charging technology provides more possibilities for mobile phone charging, making life more convenient. Despite some limitations, with the advancement of technology, the future of wireless charging is worth looking forward to and is expected to become the mainstream charging method.
