Wireless charging is also known as wireless Power Transmission WPT (Wireless Power Transmission) wireless charging 7 coil , based on coupling wireless charging 7 coil electromagnetic field as the medium to achieve power transmission. For electric vehicles with wireless charging wireless charging 7 coils , mostly through the power supply coil arranged on the ground andThe electric coil at the bottom of the vehicle wireless charging 7 coils , through the magnetic resonance generated between the coils to replace 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 fixed in the appropriate position in the cab Wireless charging 7 coils ; 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; Secure the bit of the wireless chargerAfter making sure that it is stable and will not slide, put the phone on and charge it.
On the right side of the wireless charging 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 proper cabPosition, 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.
Open the back cover of the smartphone, then take out the wireless charging receiver and prepare the Wireless charging 7 coil ; Or will it be double-sidedThe protective layer of rubber is peeled off; The next task is to connect the receiver's metal shock to the smartphone battery wireless charge 7 coil , which is the most difficult part of the whole process. However, as long as you are careful to ensure that each metal shock is connected together, it can be done.
The ordinary 555 time base circuit frequency is designed to be 8KM standby, with 0.8 enamoured wire on the diameter of 5 mm cylinder 11 times 9 layers of spinning to make two spare, the power supply uses 19V switching power supply (remember, must switch power supply), make a charging circuit (with your ownLike a wired charger, a transmission cable is needed to transmit electricity to the device, but the device that needs to be charged can be charged by contacting the wireless charging base.
2, wireless charger usage: the mobile phone standard charger and data cable connected to the wireless charger, and then the mobile phone is/horizontally placed in the wireless charger base left and right center position, you can achieve wireless charging, the indicator light will have a breathing effect, 5 seconds after the extinguish, plug and play, convenient and quick.
3, 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 then converted into a current to be transmitted to the intelligent terminal. System workWhen 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.
4, wireless charging methods include electromagnetic induction, magnetic resonance, electric field coupling and radio wave transmission, wireless charging of mobile phones mostly uses the principle of electromagnetic induction. Electromagnetic induction wireless charging, when the current of the power supply through the coil (wireless charger's power supply coil) will generate a magnetic field, other unenergized coil (mobile phone side of the power coil)Near this magnetic field, an electric current is generated to charge the phone. As shown below.
5, also similar to a transformer, input from the primary coil, and then generate 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. At present, there are three main methods: electromagnetic induction, magnetic resonance and radio wave.
1, 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.

2, the principle of wireless charging technology is "magnetic electricity", simply put, through the charging device and the mobile phone device installed on the two "magnetic equipment" mutual induction and formation of current.At present, products supporting wireless charging have appeared in mobile phones, electric vehicles, smart furniture and other fields. Among them, in the mobile phone industry, the "Qi standard" is the most common, and Qi labels are often used in the packaging of many mobile phones and wireless chargers. 3, 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.
4, the basic principle: the use of electromagnetic induction type, that is, the primary coil oneAlternating current of a fixed frequency generates a certain current in the secondary coil through electromagnetic induction, thereby transferring energy from the transmission end to the receiving end.
5, mobile phone wireless charging technology is completely without the use of wires, the use of magnets for mobile phone charging technology. Mobile phone wireless charging technology, derived from wireless power transmission technology, uses magnetic resonance to transfer charge in the air between the charger and the mobile phone, coil and capacitor form resonance between the charger and the mobile phone, to achieve efficient transmission of electric energy technology.
1, the distance of the wireless charger can only be effective within the coil range of the charger, more than the distance can not receive charging, each manufacturer's product is different, can not be universal. 2, we often say that wireless charging actually has great limitations, the effective distance is generally only 8 mm -15 mm, in this range can be normal wireless charging, the so-called space is separated by a mobile phone shell empty only. If there is a metal interval, it will affect the normal charging.
3, small power wireless chargingElectricity usually uses electromagnetic induction, such as the Qi method of charging mobile phones, but ZTE's electric vehicle wireless charging method uses induction. High-power wireless charging usually adopts a resonant mode (most electric vehicle charging uses this mode) by the power supply device (charger) to transmit energy to the electric device, which uses the received energy to charge the battery, and at the same time for its own operation.
