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 at the time, but Tesla didn't have the money to do it, and didn't do it until after his deathPresent.
2, 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. Electromagnetic waves will spread outward and their efficiency will rapidly decline because it follows the inverse square law of distance. 3. However, throughout Tesla's life, he failed to realize the idea of wireless power transmission over long distances. From a scientific point of view, this kind of transmission of electricity is technically very bigThe instability, and the efficiency in power transmission cannot be fixed, will soon spread out, if the wireless power transmitter sends out 1 million watts of power, the electrical equipment on the other side of the world can only receive 10 watts.
4, the reason should not be a matter of scientific principles, but from the technical and cost aspects. Tesla's wireless power transmission technology has problems with electromagnetic radiation and efficiency, electromagnetic waves will spread out and 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 pump a million watts of power into it all the time,Even if the power side only wants to receive 10 watts of power from it.
5, also is not, special occasions wireless transmission technology will still have its incomparable advantages.
6, this "high frequency and high voltage" through the air transmission, can achieve long-distance wireless transmission, reach the receiving end, and has no adverse effects on the human body. Tesla's big discovery was that by converting high-voltage current into high-frequency high-voltage current, electricity could be transferred infinitely. Therefore, the Tesla coil is not only a masterpiece of wireless transmission technology, but also a practitioner of the long-sought "free energy" concept.
New technology, efficiency equal to slow charging, only suitable for home?The logic behind the wireless charging technology applied by the German WIFERION, which was acquired by Tesla, in the modified Model 3 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.
First of all, Tesla's wireless charging technology uses the principle of electromagnetic induction. This technology can transmit energy through a special electromagnetic field, so thatTesla cars 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. According to WiTricity's website, the company's wireless charging technology can achieve a charging efficiency and speed close to that of conventional home charging piles, and it will charge 90% to 93% from the grid to the battery. Charging power will be able to reach 6-11kW, or even higher; The working distance between the ground transmitter and the receiving end of the vehicle can reach 10-25 cm, and most of the pure electric runningCars, sedans and city SUVs can be normally adapted.
The charging process of Tesla takes about 12 hours, but when using a home charger, the voltage may drop due to the peak load of the transformer, 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.
Tesla Y charging mode Touch switch on touch screen. To charge at a public charging station, you need to connect an adapter to the charging connector at that station. Adapters that are commonly used in public areas will come alongDepending on the charging device being used, you may need to start and stop charging using the controls on the charging device.
Adjusting the Tesla's charging limits is very simple: First, tap the battery level icon on the screen to enter the charging Settings screen; Next, click the "Set Limits" button, and then select the desired charge level by dragging the arrow above. For daily use, the arrow is usually set on the leftmost scale line, that is, 50% power, while for long-distance travel, the arrow can be dragged to the rightmost, that is, 100% power; Finally, click [Finish] to complete the setupBuy.
Click the power symbol on the screen to bring up the charging setting interface; Click the Set Limits button, then drag the arrow position above the pattern; In daily life, the leftmost scale line is 50%, and each scale line is 10%; On road trips, the right-most mark is 100%; Click Finish to complete the setup.
First of all, the user needs to update the APP. In the interface of the main page, find and click the "Appointment" button to enter the setting link. During the setting process, please note that the timed charging and scheduled departure function cannot be enabled at the same time, which is required by the userChoose between the two. Once one of these is selected, such as timed charging, the user can further adjust the current amperage at the charging interface to meet individual needs.
The adjustment process is simple and straightforward: just click the power icon on the screen, go to the charging Settings screen, select the "Set limits" option, and drag the arrow to adjust the scale above the pattern. In daily use, it is recommended to set near the 50% scale line, each scale represents 10%; On road trips, the maximum scale is 100%. Convenient charging control The charging limit feature embodies Tesla Model Y usersFriendliness.
