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 wireless charging power of up to 12KW, and the fastest energy per hour is 80 kilometers.It could take about six hours to fill.
For example, Tesla models turn on FSD to automatically replenish the vehicle after arriving 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 vehicle charging plugs are not shared at present, just like mobile phones, cars, SUVs, trucks and other different types of different brands of vehicles can use the same charging plate.
First of all, Tesla's wireless charging technology uses electromagnetic sensingThe principle of response. 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.
According to media reports, Tesla recently launched a $300 "wireless charging platform" that can charge up to three devices simultaneously. This wireless charging pad can provide up to 15 watts of charging power for every device that supports the Qi wireless charging protocol, including iPhone, Android or AirTo transmit electrical energy resonant magnetic wireless charge A charging method. It uses electromagnetic energy transfer devices (such as transmitters and receivers) to achieve wireless transmission of electrical energy. The transmitter generates an electromagnetic wave called a magnetic field, which can be transmitted to the receiver through the air or its resonant magnetic wireless charge. After receiving these electromagnetic waves, the receiver converts them into electricity and uses them to charge the battery.2, the above is the schematic diagram, the principle is the principle of electromagnetic induction.
3The working principle of the wireless charger: The electromagnetic induction principle is adopted, and the energy coupling through the coil is realized. 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.
4, electromagnetic induction: the primary coil of a certain frequency of alternating current, through electromagnetic induction in the secondary coil to produce a certain current, so as to transfer energy from the transmission end to the receiving end. It is the first generation of mobile phone wireless charging technologyMature, but only single to single short-range charging (qi standard, within 1cm, within 5 watts), and not similar to WiFi single-to-multiple charging.
1, wireless charging methods include electromagnetic induction, magnetic resonance, 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 supply coil) will generate a magnetic field, other unenergized coil (handProximity to the magnetic field generates an electric current that charges the phone. As shown below.
2, wireless charging system mainly uses the principle of electromagnetic induction. Wireless charger refers to the charger that does not need to be connected to the terminal device that needs to be charged without the traditional charging power cord, using the latest wireless charging technology, through the use of the magnetic field generated between the coils, the magic transmission of electrical energy, inductive coupling technology will become a bridge connecting the charging base station and equipment.
3, electromagnetic induction type primary coil of a certain frequency of alternating current, through electromagnetic induction in the secondary coil to produce a certain current, therebyEnergy is transferred from the transmitting end to the receiving end.
4, it is the first generation of mobile phone wireless charging, the technology is mature, but only single to single short-range charging (qi standard, within 1cm, within 5 watts), and can not be similar to WiFi single-to-multiple charging.
5, finally put the phone on the unlimited charger, note that the wireless charging induction area of the phone is generally the middle of the phone.
