CarThe breakthrough of wireless transmission technology is to find a way to "catch" electromagnetic waves, that is, to use the "resonance" principle of physics - two objects with the same vibration frequency can efficiently transmit energy. The system consists of the main circuit located outside the car and the secondary circuit, rectifier and drive system located inside the car.
The working principle of wireless charging comes from electromagnetic induction, through the use of a pair of coils between the electromagnetic induction to achieve charging, wireless charging products are using this technical principle. Car wireless charging technology also saves part of the space in the car, the phone needs to be charged, only need to handThe machine can be placed on the charging board, it should be noted that on the premise of using wireless charging technology, the phone needs to support wireless charging technology.
The working principle of the wireless charger is to use electromagnetic induction between a pair of coils to achieve charging. Automobile wireless charging technology can not only save the space in the car, but also solve the safety hazards such as leakage and running of the charger. It is important to note that mobile phones need to support wireless charging technology in order to use wireless chargers. Wireless charging is a new feature of electronic products, using wireless charging technology can be more convenient and safe to charge mobile phones.
Wireless chargingThe principle 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.
Principle of wireless charging Electric vehicle wireless charging technology transmits electric energy to a certain range on the ground in the form of high-frequency alternating magnetic field through the power supply guide rail buried under the groundInside the vehicle receiving end, which in turn supplies power to the vehicle energy storage device. 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.
[Pacific Automotive network] BMW 5 series can modify the wireless charger, the principle of 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, by using the magnetic field generated between the coils, the transmission of electric energy. Inductive coupling technology will become a bridge connecting charging base stations and devices.
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 your phone in a wireless charger and it will start charging.
2, first of all, fix the car wireless charger to the appropriate position in the cab, and connect the data cable connector of the wireless charger to the steamOn the cigarette lighter interface of the car, the other end is connected to the wireless charger, and after fixing the wireless charger, ensure that the wireless charger will not slip off, and the wireless charger can be used normally.
3, the steps to start using the car wireless charger are as follows: First, place the wireless charger in the car, and connect it to the power supply through the charging cable to ensure that the device is firmly connected. Next, check if your phone has wireless charging capability. If it is supported, gently place the phone on the top of the charger, making sure that the charging sensing area of the phone is aligned with the interface of the charger, so as to ensure efficient charging.
4, first of all, find the appropriate location of the cab and install the car wireless charger; Next, connect one end of the USB data cable of the wireless charger to the cigarette port of the car, and the other end is connected to the charger; Make sure the charger is securely installed and will not slide while driving, and then place the phone on the charger to start wireless charging. Wireless charging technology comes from the principle of radio energy transmission, which is mainly divided into two modes of low power and high power.
5, to achieve wireless charging in the car, you need to fix the car wireless charger in the right position in the cab, and then connect the USB data cable to the carIt will start charging.
2, after purchasing the appropriate wireless charging equipment, it should be fixed in the car convenient and does not interfere with the driving position. Then, connect one end of the USB data cable of the wireless charging device to the wireless charger and the other end to the cigarette lighter interface of the car. After ensuring that the charger is firmly fixed, the phone can be put on to start charging.
3, 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, after fixing the wireless charger, ensure that noThe wire charger will not slip, and the wireless charger can be used normally.
