< ul>1, fixed wireless charger. The owner needs to buy a suitable wireless charger equipment, and then fix the wireless charger on the vehicle, and the fixed position should be convenient for the owner to take. Connect the cigarette lighter. One end of the USB data cable of the wireless charging device is connected to the wireless charger, and the other end is connected to the car cigarette lighter interface. Put it in your phone. Put the phone in wirelessIn the charger, the phone will start charging.
2, BMW x3 center control panel under the storage grid is set with USB interface and 12V power supply, can be used to charge mobile phones. BMW x3 series only the top of the standard with wireless charging, but the lack of wireless charging car series can be optional wireless charging this configuration. Wireless charging only needs to put the mobile phone with wireless charging function on it, and it can be automatically charged.
3, installation and connection Select the appropriate car wireless charger, and fixed in the appropriate position of its cab, to ensure that stable will not slide. Will wireless charger USBOne end of the data cable is connected to the car cigarette outlet, and the other end is connected to the wireless charger. Automotive wireless charging technology is derived from radio energy transmission technology, which is divided into two ways: low-power wireless charging and high-power wireless charging.
4, as long as the mobile phone model supports wireless charging function, it can be charged on the car wireless charger. If the mobile phone can not support, you can connect a wireless charging patch to the mobile phone, so that the patch is connected to the charging interface of the mobile phone, and then use a data cable from the usb interface of the bracket to connect to the usb in the car, and finally fix the mobile phone in the car chargerOn the rack, adjust the Angle.
5, first of all, the car wireless charger fixed to the appropriate position in the cab, the wireless charger data cable connector connected to the car's cigarette lighter interface, the other end is connected to the wireless charger, fixed after the wireless charger, ensure that the wireless charger will not slip, the wireless charger can be used normally.
1, electromagnetic induction type. Wireless car charging works by transferring energy through a magnetic field between the charger and the electrical device,No physical connection is required to help the electric vehicle obtain electricity from the power supply device, i.e. electromagnetic induction.
2, electric vehicle wireless charging technology through the power supply guide rail buried under the ground in the form of high-frequency alternating magnetic field to the vehicle running in a certain range of the receiving end of the electric energy picking mechanism, and then to the vehicle energy storage equipment power supply. When charging begins, the power transmitter PTx generates an alternating current through its coils, which creates an alternating magnetic field according to Faraday's Law.
3, wireless charging of motor vehicles is a function of some high-end models. After use, it is convenient for the driver to correct the machineSome parts of the bullet train are charged. Wireless charging can charge mobile phones, computers and other related items. Motor vehicles can be charged wirelessly, without external connectors, to avoid leakage or electricity running safety hazards.
1, compared with the traditional charging method, the wireless charging system can indeed greatly improve the convenience of charging, so that the stop is charged, and the wireless charging device has lower space demand. thisIn addition, relying on magnetic resonance wireless charging, it can theoretically be charged while walking, and even is expected to solve the range anxiety of pure electric vehicles.
2, as for the electromagnetic wireless charging scheme, aluminum can also be used to replace copper as raw materials to a certain extent, thereby reducing manufacturing costs. 3, Recently, the Ministry of Industry and Information Technology issued regulations to raise the charging power limit of mobile phones and other mobile devices to 80W, and apply wireless charging technology to electric vehicles. This means that the era of wireless charging for electric vehicles may be coming. Wireless charging technology, that is, wireless power transmission technology, is a non-contact mode of power transmission.Mainly through electromagnetic induction, magnetic resonance, radio frequency, microwave, laser and other ways to achieve.
Electric vehicle wireless charging technology is buried inThe power supply guide rail under the ground transmits electric energy in the form of high-frequency alternating magnetic field to the electric energy picking mechanism at the receiving end of the vehicle running in a certain range above the ground, and then supplies power to the vehicle energy storage equipment. When charging begins, the power transmitter PTx generates an alternating current through its coils, which creates an alternating magnetic field according to Faraday's Law.
The wireless charging principle of the car is by converting electrical energy into electromagnetic waves, which are then sent to the receiver, and then the electromagnetic waves are converted into electrical energy. Charging technology is not complex, mainly the use of electromagnetic induction and magnetic resonance, but the biggest difficulty of wireless charging is the lack of a unified standard for chargingIt takes too long, it's too inefficient, and it costs too much.
The principle of wireless charging is to use the current through the coil to generate a magnetic field, with no power of other coils close to the magnetic field, the coil will generate a current, thus charging the device. At present, the car wireless charger mainly uses the QI protocol, as long as the phone supports the protocol, you can charge through the wireless charger. In addition, the car wireless charger can also meet the needs of the mobile phone 24 hours online power, mobile phone navigation line.
Devices that use the principle of electromagnetic induction for charging, the principle is similar to that of transformers, through the emission endFor wireless charging, similar to a transformer, there is a coil in the sending and receiving end, the sending end of the coil connected to the wired power supply to generate electromagnetic signals, the receiving end of the coil to induce the electromagnetic signal of the sending end to generate current to electrical equipment such as batteries, that is, wireless charging technology requires two devices This model is not only a luxury version, all models are not equipped with wireless charging this function.

During charging, non-vehicle charging devices are connectedConfirm the input voltage signal of the contact, and continuously monitor the connection status of the charging plug and charging socket. Once there is an anomaly, the non-vehicle charging device will immediately turn off the DC power output, and disconnect the switch S1 after unloading.
1, for electric vehicles with wireless charging, mostly through the power supply coil arranged on the ground and the electric coil at the bottom of the vehicle, through the magnetic resonance generated between the coils to replace the traditional power lines for vehicle charging. This charging method requires higher spacing between the supply and receiving coils. None for electric vehiclesThe huge demand of line charging technology makes the research and development of related technologies very active.
2, electric vehicle wireless charging technology mainly uses the mutual inductance in the law of electromagnetic induction. It is also similar to a transformer, which inputs from the primary coil and then generates an induced current on the secondary coil. It mainly relies on the energy transmission between electricity and electricity, converts electricity into magnetism, and then induces electricity. Wireless charging is simply to charge electrical equipment through electromagnetic fields or electromagnetic waves without being connected by physical wires.
