1, because the mobile phone itself does not have a wireless receiving device, it must be affixed with a receiver. Now the common principle of the Tesla wireless charging pad is the Tesla coil, and a small number of them use magnetic resonance technology.
2, through the use of coils betweenThe generated magnetic field, the magical transmission of electrical energy, inductive coupling technology will become a bridge connecting charging base stations and devices. Most current chargers, such as the iPad and iPhone, charge the device's internal battery through direct contact with a metal wire. The advantage of wireless charging technology is its convenience and versatility. The disadvantages are low efficiency and can only provide electrical energy.
3, now the research is similar to radio, is the inductive phenomenon more energy ~~ there is no use of Tesla coil with features. Just look at the Tesla coil, a mini DIY coil when powered onOne meter can generate 10,000 volts of induced voltage, and there's a video with a light bulb 2 meters away, it lights itself up. But in fact, this also needs to generate electricity, the power of the person is very bad, everyone can use his electricity.
4, wireless charging technology principle Tesla wireless charging pad : Wireless charging technology uses the current magnetic effect and electromagnetic induction of these two physical phenomena. Current magnetic effect means that an energized coil will produce a magnetic field, while electromagnetic induction means that an unenergized coil will generate an induced current in a changing magnetic field.
5, wireless charging basicThe principle is to convert the current into a magnetic field, and the magnetic field is transmitted through the air and then converted into a current to be transmitted to the intelligent terminal. When the system works, the input end converts the AC mains into direct current through the full bridge rectifier circuit, or uses the 24V direct current end to supply power to the system directly. After passing through the power management module, the output direct current is converted into high-frequency alternating current through the 2M active crystal oscillator inverter to supply the primary winding.
6, for example, the circuit scheme is simple and has better cost effectiveness. The main disadvantages include the limited charging distance and the need for precise alignment between the transmitter and receiver. Magnetic resonance (resonance induced coupling) This near-field method utilizes resonanceThe logic behind the wireless charging technology applied by WIFERION in the modified version of 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.
3, Tesla can be charged in the locked car state. Tesla uses wireless charging technology that allows users to charge their batteries without plugging in a cable. This technology uses radio-magnetic energy to transmit electrical energy from one device to anotherWireless charging now. To use the Tesla Lock car wireless charging feature, you first need to install a wireless charger on the vehicle and connect it to a power source.
4, convenient: charging does not need to be connected with a wire, as long as it is placed near the charger. Technically, a charger can power multiple electrical devices, and in the case of multiple electrical devices, it can save multiple chargers, do not occupy multiple power sockets, and there is no trouble of multiple wires winding each other.
5, Tesla's official website in 2016 has published a March technical notice, that is, they developed a wireless chargingThis charging technology can allow their electric vehicles to complete such a process from 0 to 100% in 10 hours, and in the case of high-speed charging, an hour can provide the car with a driving range of about 30 kilometers.
Tesla Tesla wireless charging pad Wireless power transmission is not practical Tesla wireless charging pad Reason There is no claim of accuracy, and Tesla has never attempted 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. is not, special occasions wireless transmission technology will still have its incomparable advantages. Tesla's wireless power transmission technology has electromagnetic radiation and effectsThe problem with the rate is that the electromagnetic wave 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 keep pumping 1 million watts of power into it, even if the power side only wants to receive 10 watts from it.
