Electric vehicle wireless charging technology is buried in the groundThe lower power supply guide 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 from the ground up, 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 breakthrough of the 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 a primary circuit located outside the car and a secondary circuit located inside the car.Rectifier and drive system composition.
What is the principle of wireless charging wireless charging principle is electromagnetic induction, electromagnetic induction wireless charging is the use of electromagnetism, magnetic induction principle, that is, "electricity" and "magnetic" mutual conversion.
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 that the lack of a unified standard, charging time is too long, efficiency is too low, high cost.
Wireless charging technology is a special way of power supply, it does not need the power line, relying on the propagation of electromagnetic waves, the electromagnetic wave energy into electricity, and finally realize wireless charging. Low-power wireless charging often uses electromagnetic induction, such as the Qi method of charging mobile phones, and ZTE's electric vehicle wireless charging uses induction mode.
The principle of wireless car charger is to use ampere's law and Faraday's law, through the time-varying magnetic field generated by the power transmitter, the electromotive force is generated in the appropriately positioned power receiver, so as to charge the mobile phone. The mainstream wireless car charging has two ways of front loading and rear loading. Let's find outHow wireless car charging works.
1, the car mobile phone wireless charge fuse is generally located in the fuse box of the vehicle. The fuse box is usually located inside the dashboard under the driver's seat. The exact location may vary depending on the model and vehicle configuration. In most vehicles, you can find the fuse box by following these steps: Open the dashboard under the driver's seat. There is usually a pull handle or button to open the lid.
2. Have two fusesA box. According to the configuration table of GAC Trumpchi gs4 official website, GAC Trumpchi gs4 has two fuse boxes. One in the engine compartment, one in the cockpit dashboard. Classification of automobile fuse box: according to the classification of installed fuse, it can be divided into safety tube box and safety piece box. According to the size of the fuse, it can be divided into large fuse box, medium fuse box, small fuse box.
3. Open the vehicle's shift panel, place the wireless charging panel in a suitable position, and arrange the cable along the direction of the vehicle. Remove the plastic panel of the original wireless charging module and connect the adapter with the original USB connectorConnect to the USB module, and then insert the new connector into the original USB module. Connect the on-board transformer to the vehicle's fuse box, select the appropriate fuse slot, and insert the fuse.
4. The wireless charging module is faulty. Troubleshooting: VDS can not scan the wireless charging module. According to the circuit diagram of this model, the wireless charging module is powered by the F2/42 fuse of the meter distribution box. Check that the fuse is normal and measure that the fuse has 13V voltage. Remove the wireless charging module located below the front end of the central channel, and measure that the power supply of pin 1 of the connector of the wireless charging module is normal.
5Byd Song Pro is a mobile phone wireless charging function, its position is in front of the electronic stop rod, close to the position of the water cup holder. It is powered on automatically, there is no need to turn it on manually. Of course, BYD Song Pro EV is equipped with a mobile phone wireless charging function, the charging position is in front of the cup holder, next to the cup holder, as long as the mobile phone can be charged, very convenient.
③, the above two charger models are different, the voltage, current and power of the two chargers are different.
To this MDY-08-EV and MDY-11-EM, is to represent the charger model, for example, MDY-08-EV original charger DC output is: 5V/2A. The MDY-11-EM charger DC output is: 5V/3A, 9V/23A, 12V/67A, 10V/25A. Therefore, these two different models of chargers, the parameters are also different.
MThe DY-08-EV and MDY-11-EM are two different charger models. For example, the original charger of the MDY-08-EV has a DC output of 5V/2A, while the DC output of the MDY-11-EM charger includes several parameters such as 5V/3A, 9V/23A, 12V/67A and 10V/25A. Therefore, the two models of chargers are different in terms of parameters. The above information is for reference only.
Different appearance mdy08eh and es are respectively the chargers of Mi 5 and Mi 6, they are slightly different in size, the former size is more repairedLong, the size of the latter is short and thick, and the volume of the two is similar. mdy08eh is a black color, and it only has one color, black. The mdy08es has two colors, white and gray, the bottom is gray, and the top half is white.
1, first of all, find and remove hidden screws, Mercedes-Benz c car radio charger device will be covered under the panel or other easily overlooked location, need to find and remove any fixed devices, such as turnbuckles and clasps. Need to useAppropriate tools to assist in removal. Second, remove the panel and control module so that the charger body can be easily accessed. Avoid damaging any surrounding parts. 2, in terms of interior, the new car still maintains the design of the current model, including the full LCD instrument and the large-size center control screen, the overall design resembles the Mercedes-Benz S-class, whether it is a sense of science and technology or a sense of grade, are outstanding in the same level, deeply loved by users. In terms of configuration, the new car cancels the wireless charging function and becomes an optional configuration.
