Wireless charging, also known as inductive charging, non-contact inductive charging, from wireless powerTransmission technology is the use of near-field induction, that is, inductive coupling, by the power supply device (charger) to transmit energy to the electrical device, the device uses the received energy to charge the battery, and at the same time for its own operation.
"Wireless charging" uses a special device to convert power from an electrical outlet into rechargeable airwaves that can charge electronic devices directly after the wires have been discarded. Wireless charging basically transfers energy through a magnetic field.
Mobile phone wireless charging refers to the meaning that the charger and the electrical device can be connected to the phone without wires.
1, wireless charging refers to a charging method that can charge electronic devices without the traditional wired charging method. Wireless charging technology allows us to eliminate the tedious charging process, making charging more convenient and intelligent. Wireless charging technology has been widely used, such as wireless charging car technology has begun to achieve commercial production.
2, the current wireless charging on the vehicle refers to a wireless charging board in a certain position of the central control, which can charge the mobile phone, as for the vehicle itselfWireless charging for battery charging is not a new technology, but only a very small number of vehicles are currently available as an option. 3, accessories include a magnetic iPhone case with MagSafe and two official wireless chargers, and the iPhone 12 May have a magnetic positioning function so that the phone can more easily align with the position on the charging pad.
4, do not rely on the charging cable to charge the electric vehicle, through electromagnetic induction, magnetic resonance, radio frequency and other ways to achieve non-contact power transmission. Electric vehicle wireless charging has no exposed connector and can be adapted to a variety of conditionsBad environment and weather, to avoid leakage, electricity and other safety hazards. Easy to use, the vehicle only needs to park to a fixed location to charge, and no supervision is required. The power supply and transformer are hidden underground to save space.
Basic principle: The use of electromagnetic induction, that is, the primary coil of a certain frequency of alternating current, through electromagnetic induction in the secondary coil to produce a certain current, so as to transfer energy from the transmission end to the receiving end.
What is the principle of wireless charging? Will wireless charging become popular? 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.
Using the principle of electromagnetic induction charging equipment, its principle is similar to the transformer, through the transmitter and receiver end set coil, transmitter coil under the action of power to send electromagnetic signals, the receiving end coil receives electromagnetic signals and convert electromagnetic signals into current, so as to achieve the purpose of wireless charging.
