Basic principle of wireless charging Wireless charging coil type , that is, the current is converted 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. 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.
NoneThe line charging system mainly adopts the principle of electromagnetic induction. 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 wireless charging coil type The latest wireless charging technology, through the use of the magnetic field generated between the coils, the magical transmission of electrical energy, inductive coupling technology will become a bridge connecting the charging base station and equipment.
Wireless charging methods include electromagnetic induction, magnetic resonance, electric field coupling and radio wave transmission, etc. Wireless charging of mobile phones mostly uses the principle of electromagnetic induction. Electromagnetic induction type noneWire charging: When the current of the power supply passes through the coil (the power supply coil of the wireless charger), a magnetic field will be generated, and other unenergized coils (the electric coil of the mobile phone) will be close to the magnetic field, and the current will be generated to charge the mobile phone. As shown below.
2, same size. The same size and as close as possible, otherwise it will have no effect, low conversion efficiency.
3, the transmitting end is often multiple strands of silk-covered wire, multiple strands of thinner enameled wire or gauze wrapped wire wound inductors are used in relatively high frequency circuits, such as the magnetic antenna rod coil of the radio, the short-wave radio coil, the high frequency transformer coil of the liquid crystal display lighting circuit, etc., often use multiple strands of wire and wound.
4, Apple calls this system sensor "primary depth camera system". The iPhone X's front-facing camera has 7 megapixels and supports virtual backgroundMagnetic resonance generated between coils replaces traditional power lines to charge vehicles. This charging method requires higher spacing between the supply and receiving coils.
2, how the car wireless charging vehicle wireless charging how to use the car wireless charging method is: the car wireless charging 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.
3. On the right side of the wireless charging panel is a switch. Press this switch to give the panel accessElectricity, and put 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.
4, 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, and fix the wireless chargerAfter that, make sure that the wireless charger will not slip off, and the wireless charger can be used normally.
