If you use vivo mobile phone, wireless charging is also known as inductive chargingOr non-contact inductive charging, based on the principle of electromagnetic induction, the device that needs to be charged can be charged by contacting the wireless charger after being energized.
First, we need to confirm whether our millet 11 supports wireless charging function. You can view this information in your phone's Settings. Enter "Settings" - "Battery and Performance" - "Wireless charging", if the "wireless charging" option appears, it indicates that the device supports wireless charging. After confirming that the device supports wireless charging, we need to prepare a wireless charger that supports the Qi standard.
Principle of wireless charging The principle of wireless charging is to transfer energy to the need to charge through electromagnetic induction or electromagnetic radiationElectrical equipment. Specifically, wireless charging is divided into two ways: electromagnetic induction and electromagnetic radiation. Electromagnetic induction: Through the principle of electromagnetic induction, the current at the transmitting end is converted into a magnetic field, and then the energy is transferred to the receiving end through the magnetic field, and then the energy is converted into current, so as to achieve wireless charging.
Electromagnetic induction: Simple and efficient intimate contact electromagnetic induction, just like a pair of tacit dancers, the sending end and the receiving end transfer power through the induction magnetic flux. It is known for its simple structure, high efficiency and low cost, and is especially suitable for close-range device charging. However, it also has limitations, limited transmission distance and counterpointTo charge a device, the device must be accurately aligned, as shown in Figure 4-1.
Wireless charging systems typically include two key components: a charger and a charging device. The charger transmits energy to the charging device through electromagnetic induction without physical contact. This mode of energy transfer relies on electromagnetic fields, and the charging process is achieved when there is an appropriate distance and location between the two devices. The core of wireless charging technology is electromagnetic induction principle. When a coil is fed with alternating current, it creates an alternating magnetic field.
1, clear answer: general mobile phones do not have wireless charging function. Mobile phone wireless charging is not a standard feature on all mobile phones. At present, most of the mobile phones on the market still use the traditional wired charging method, which needs to be charged by connecting the charger and data cable. Wireless charging is usually an additional feature that requires a phone model with this feature to be selected at the time of purchase. 2, wireless charging, also known as inductive charging or non-contact inductive charging, based on the principle of electromagnetic induction, does not need to transfer electricity to the device like the traditional wired chargerThe device that needs to be charged can be charged by touching the wireless charging base.
