Wireless charging, also known as inductive charging, non-contact inductive charging, is the use of near-field sensing, that is, inductive coupling, by means of a power supply device (charge transmitting device, such as a charger) to transfer energy to a powered device (charge receiving device) For example, a cell phone, the device uses the received energy to charge the battery and at the same time is used for its own operation. Since the charging transmitting device and the charging receiving device transmit energy by inductive coupling, the wires are not connected between the two, so that the charger and the powered device can be exposed without conductive contacts.

And receiving, by the first wireless communication module, a value of the wireless charging current detected by the second detecting module. The wireless charging prompt system of claim 11, wherein:
The prompting module is located in the charging receiving device, and is connected to the computing determining module to receive the first prompting signal and the second prompting signal. The wireless charging prompt system of claim 11, wherein:
The prompting module is located in the charging and transmitting device, and is connected to the second wireless communication module to receive the first prompting signal and the second prompting signal by the second wireless communication module;
The calculation determining module sends the first prompt signal and the second prompt signal to the charging transmitting device by using the first wireless communication module. The wireless charging reminding system of claim 8, wherein the calculating and determining module obtains wireless charging efficiency according to the size of the wireless charging current, including:
The calculation determining module obtains the wireless charging efficiency according to the obtained value of the wireless charging current detected by the first detecting module and the value of the wireless charging current detected by the second detecting module. :
E=I ₁ /I ₂ ×100%
Wherein, I ₁ for charging the first wireless module detection value detected by the current magnitude, I ₂ for the second wireless module is detected by detecting the charge current value, E for wireless charging efficiency.
