1, 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.
2, the breakthrough of vehicle wireless power transmission technology is to find a way to "grasp" electromagnetic waves, that is, to use the "resonance" principle of physics -Through electromagnetic induction, a certain current is generated in the secondary coil, thereby transferring energy from the transmission end to the receiving end.
2, the basic principle of wireless charging is to convert the current into a magnetic field, and the magnetic field is transmitted through the air and 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.
3, wireless charging system mainly uses the principle of electromagnetic induction. There is noWire 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 the bridge connecting the charging base station and equipment.
1, the working principle of the new energy vehicle charger mainly includes two key steps: power supply and single current control. During the power supply phase, the on-board charger passes through its outputThe port's "charge request signal" line actively sends a charge request to the vehicle's control center, the vehicle controller (VCU).
2, new energy vehicle charger is a power electronic system, mainly converts the 12V voltage of the car cigarette lighter socket into 5V USB voltage, and charges electronic products through the charging line. It can convert 12V-36V direct current into 5V direct current to provide charging services for on-board mobile devices.
3, the working principle of the new energy vehicle charger involves the operation of the power electronic system, which is mainly composed of the power circuit and the control circuit groupAgreed. The DC and DC converters in the power circuit, consisting of transformers and power tubes, play a key role. The control circuit takes the controller as the core, and through the CAN communication with the BMS, the control power circuit charges the lithium battery pack according to the three-stage charging curve.
4, the vehicle power battery provides energy, and the motor provides power to achieve driving. The driving of electric vehicles consumes the energy of the battery, and the battery needs to be replenished after the consumption of electricity, through the process of transferring the electric energy in the grid or other energy storage devices to the battery of the vehicle. The electric energy in the power grid or energy storage equipment needs to pass through the charging equipmentConversion to match the technical characteristics of the electric vehicle power battery to complete the charging.
5, the output filter circuit is connected to the DC output end. Now they are calling for low-carbon travel, reducing atmospheric emissions, protecting the ecological environment and saving resources. Electric vehicle is a kind of new energy, pollution-free green transportation, which is used more and more widely. Electric vehicles can only be powered by charging for intelligent travel, charging guns and charging piles are basic supporting facilities, and they also need to be perfected in design to ensure the normal use of electric vehicles for charging.
First of all, fix the car wireless charger to the appropriate position in the cab, connect the data cable connector of the wireless charger to the cigarette lighter interface of the car, and connect the other end to the wireless charger, after fixing the wireless charger, ensure that the wireless charger will not slip, and the wireless charger can be used normally.
How to use the wireless charging with the car (how to use the wireless charging with the car) How to use the wireless charging with the car: Fix the wireless charger to the appropriate position in the cab, and connect the data line of the wireless chargerThe head is connected to 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 can be used normally.
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.
First the car wireless chargingThe device is fixed in place in the cab of the Chevrolet Coruse. Secondly, connect one end of the USB data line of the wireless charger to the car cigarette point, and connect the other end to the wireless charger. After it is confirmed that it is stable and will not slide, put the phone on and charge it.
1, the use of wireless charging of the car phone bracket: Simply put, the wireless charging module and the mobile phone bracket are combined.
2. Air outletHanging type. Installed in the air conditioning outlet position, the disadvantage is that due to different models, the fixed structure and position are limited, unable to rotate and adjust the Angle; The advantage is that it is fixed and reliable; Magnetic 360-degree rotating phone stand. Installed in any plane position that is convenient for the driver to operate, the disadvantage of the magnetic field will affect the mobile phone signal magnetic field, the paste will be removed and there will be a mark, the advantage is that it is small, flexible, does not block the line of sight, and can be taken off with one hand to answer the phone.

4, instrument panel suction type. As the first generation of mobile phone holder, the disadvantage is that the suction cup is not firm, and the mobile phone is easy to fall off; Advantages: The dashboard can be placed in the most comfortable position; Front baffle suction plate. Installed on the front windshield, the disadvantage is blocking the line of sight, unsafe; Advantages: snake-like rod structure, easy Angle adjustment; The air outlet is suspended.

3, generally seen wireless charging, the use of "current magnetic effect" and "electromagnetic induction" principle. In 1819, Danish scientist Elster observed that if there is an electric current on a wire, a magnetic field will be generated around it, which can deflect the north finger. Later generations have further found that the wire is encircled into a ring, or even wound into a coil, and the magnetic field generated will be stronger and more concentrated, which is called the "current magnetic effect."

The main principle is: the way of wireless charging is electromagnetic induction, magnetic resonance, electric field coupling and radio wave transmission, etc. Most of the wireless charging of mobile phones uses the principle of electromagnetic induction.
5, wireless charging is also known as inductive charging or non-contact inductive charging, based on the principle of electromagnetic induction, it is not necessary to transmit electricity to the device like the traditional wired charger, but the device that needs to be charged can be charged by contacting the wireless charging base.
