The principle of wireless charging is that through near-field induction wireless charging cutting , the wireless charging device conducts energy to the charging terminal device wireless charging cutting , 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 ensures that there is no exposed conductive interface. Not only does it eliminate cluttered transmission lines between devices, yeahElectronic devices that are in constant contact with conductive media such as liquids, such as electric toothbrushes, are also safer.
Therefore, the formation of wireless charging cutting a "closed loop". Wireless charging power wants to be larger, but the battery will be hot, easy to produce thermal runaway; However, if the wireless charging power is not large, there is no need to get on the car. Unless next, the wireless charging end is connected to the thermal management system of the tram, which can be combined with real-time wireless charging cutting to understand the state of the electric vehicle battery charging, which must take into account the algorithm, communication and other aspects.
The basic principle of wireless charging is to convert the current into a magnetic field, which 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.
The so-called electromagnetic induction principle refers to the part of the conductor of the closed circuit in the magnetic field to cut the movement of the magnetic induction line, the conductor will produce current, this phenomenon is called electromagnetic induction phenomenon. The current generated by electromagnetic induction in the closed circuit is called induced current. It is the inductive current that replaces the alternating current transmitted by the power adapter to complete the mobile phone charging process.
Wireless charging is done according to the principle of electromagnetic induction and nuclear magnetic resonance. Wireless charging technology, derived from wireless power transmission technology. Is the use of near-field induction (inductanceCoupling), the current flowing through the coil creates a magnetic field. The proximity of other unenergized coils to this magnetic field will generate an electric current. Realize energy transfer.
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, which is stored in the battery of the device. The principle of energy conduction is inductive coupling, which ensures that there is no exposed conductive interface. It can not only eliminate messy transmission lines between devices, but also be safer for electronic devices such as electric toothbrushes that are often in contact with conductive media such as liquids.
Electromagnetic induction wireless 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 near the magnetic field, and the current will be generated to charge the mobile phone. The advantages of wireless charging safety: no power contact design, can avoid the danger of electric shock.
