Electromagnetic wave is converted into electric energy, and charging equipment is charged with the electric energy.
Alternatively, electric energy transmitting terminal sends radio frequency electromagnetic, the radio frequency electromagnetic Portable power energy, power to receiver
No more than 10 watts.
The receiver can be multiple, and electric energy transmitting terminal can send radio frequency electromagnetic to multiple receivers simultaneously.
The receiver is used for the radio frequency electromagnetic for receiving the transmission of electric energy transmitting terminal, then converts the radio frequency electromagnetic
For electric energy, then charging equipment is charged.
The receiver can be contained in charging equipment, can also turn into a single device, receive electric energy hair
After the electric energy that sending end is sent, charged for charging equipment.
By taking smart mobile phone as an example, because many smart mobile phones can all configure a protective case.Receiver can be arranged at intelligence
In the protective case of energy mobile phone, the radio frequency electromagnetic received is being converted into electric energy by protective case, has micro USB by smart mobile phone
Electrical interface charges to smart mobile phone.
Receiver, which is alternatively arranged as a single accessory, to be present, and the present invention does not limit its specific form, can set and treat
The inside of charging equipment, or individualism.
After electric energy transmitting terminal sends radio frequency electromagnetic to receiver, in addition to step：
Obtain the charge parameter of charging equipment；
According to the charge parameter, the transmission power of the radio frequency electromagnetic is adjusted.
Connected by Bluetooth communication, obtain the charge parameter of charging equipment, enter here by taking residual power percentage as an example
Row explanation.
Charge parameter can be the parameter such as charge power, charge efficiency, charging current, charging voltage to represent, the present invention
Its specific parameter is not limited.Illustrated by taking charge power as an example.
When electricity ratio is relatively low, charge efficiency is higher, can improve charge power, to realize charging speed faster
Degree.
For example, when charge parameter is less than 60%, charge power may be configured as 10 watts；When charge parameter is more than 60%,
Charge power is arranged to 6 watts.
Charge power can be controlled by the transmission power of radio frequency electromagnetic.
In addition, charge parameter can be charge efficiency, when charge efficiency is higher, transmission power can be increased, reach quick
The purpose of charging.
Alternatively, adjustment process could be arranged to a continuous process of dynamic.Transmission power is with charge parameter with one
Functional relation limits, so as to the adjustment of transmission power.
In general, transmission power is bigger, and entrained electric energy is bigger, and caused radiation is also bigger, so transmitting work(
Rate should limit.Can be that one threshold value of transmission power setting radiates to control caused by it.
By charge parameter, the adjustment to transmission power, optimize charging process, improve the usage experience of user.
In addition, when the electricity ratio of charging equipment is relatively low, transmission power can also be increased, accelerate charging process, so as to
Charging equipment shuts down because of low battery.
By electric energy transmitting terminal and the Bluetooth communication of charging equipment, optimize charging process.
It should be appreciated that above-mentioned step does not have strict execution sequence, it is all to be contemplated that and do not influence the reality of function
Existing change all should be within the scope of the present invention.
