Magnetic fieldOn the larger transmission distance, the transmission power can still reach several kilowatts.
Not only Japan, there are many countries are studying wireless charging road, at the end of last year, the world's fourth largest automobile manufacturer Stellantis announced on the official website, their innovative dynamic induction charging technology after years of research and months of testing proved successful wireless charging coil spacing The road "Arena del Futuro" for wireless car charging testing has been officially opened. So now wireless charging technology is also a very hot doorRanks.
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.
The principle of wireless charging is that through near-field induction, the wireless charging device conducts energy to the charging terminal device, and the terminal device converts the received energy into electrical energy and stores it in the battery of the device. The principle of energy conduction is inductive coupling, which can ensure that there is no exposed conductive interface, which can not only save the messy transmission line between the equipment, but also be safer for electronic devices such as electric toothbrushes that are often in contact with conductive media such as liquids.
It is the first generation of mobile phone wireless charging, the technology is mature, but it can only be single-to-single short-range charging (qi standard, within 1cm, within 5 watts), but not the classSingle to many charging like WiFi.
The principle of wireless charging technology is electromagnetic induction, magnetic field resonance, radio wave and so on. Electromagnetic induction type primary coil a certain frequency of alternating current, through electromagnetic induction in the secondary coil to produce a certain current, thereby transferring energy from the transmission end to the receiving end.
Radio waves. The principle is to convert environmental electromagnetic waves into current and transmit current through a circuit. This way the transmission distance is greater than 10 meters, which is suitable for long-distance low-power charging, and can also realize automatic charging anytime and anywhere. WiFi wireless charging. It mainly consists of two componentsOne is a Wi-Fi access point (router), and the other is a custom charging sensor.
The principle is to use electromagnetic induction, that is, to divide a transformer into two halves, rely on electromagnetic induction to charge the part to get the corresponding voltage. Wi-Fi, the Chinese name for wireless fidelity, is a technology that can connect terminals such as personal computers and handheld devices (such as pads and mobile phones) to each other wirelessly, in fact, it is a high-frequency radio signal.
Wireless charging system mainly adopts the principle of electromagnetic induction, and realizes the energy coupling through the coilThe transfer of energy. 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.
Wireless charging, also known as Wireless Power Transmission (WPT), is a coupled electromagnetic field as the medium to achieve electrical energy transmission. For wireless charging of electric vehicles,Through the power supply coil arranged on the ground and the electric coil at the bottom of the vehicle, the magnetic resonance generated between the coils replaces the traditional power lines to charge the vehicle. This charging method requires higher spacing between the supply and receiving coils.
How to wireless charging the car wireless charging How to use the car wireless charging method is: the car wireless charging is fixed in the appropriate position in the cab; Connect one end of the USB data cable of the wireless charger to the car cigarette port and the other end to the wireless charger; After fixing the position of the wireless charger, make sure that it is stable and will not slide, put the phone on and charge it.
In wireless chargingOn the right side of the panel is a switch. Press this switch to power the panel and place the phone on it. Many cars will be equipped with wireless charging capabilities, and it is not uncommon for many mobile phones to support wireless charging capabilities. Trumpchi is an independent brand with many car and suv models. Trumpchi's SUVs include gs3, gs4, gs5, gs8, gs7 and so on. gs8 is a model with good sales volume of Trumpchi, which is a medium-sized suv.
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 cigarette lighter interface of the car, the other endConnect to the wireless charger, after fixing the wireless charger, ensure that the wireless charger will not slip off, and the wireless charger can be used normally.
