Lower obtained every other embodiment, shall fall within the protection scope of the present invention.
Currently, existing wireless charging system cannot fill under conditions of no condition communicates wirelessly in battery-end
Electricity completes control transmitting terminal when either battery-end disconnects suddenly and stops charging, to cause device or cell damage etc..It is based on
This, a kind of wireless power control device provided in an embodiment of the present invention and method, in the state that transmitting terminal and receiving terminal do not communicate
Under, it can suddenly be disconnected when battery or power off transmitting terminal subjectivity when fully charged, to protect battery and receiving terminal device.
For ease of understanding the present embodiment, dress is controlled to a kind of wireless power disclosed in the embodiment of the present invention first
It sets and describes in detail.
Fig. 1 shows wireless power control device schematic diagram provided in an embodiment of the present invention.
As shown in Figure 1, present embodiments providing a kind of wireless power control device, including wireless receiving end and wireless transmission
End, wireless receiving end includes voltage detecting circuit 10, fictitious load switching circuit 20, processor 30 and battery 40；Processor 30
It is connected respectively with voltage detecting circuit 10 and fictitious load switching circuit 20, voltage detecting circuit 10 is connected with battery 40；
Voltage detecting circuit 10, is connected with battery, the information of voltage for detecting battery-end, and information of voltage is sent
To processor 30；
Processor 30, for when the information of voltage of battery-end is higher than predeterminated voltage, control fictitious load switching circuit 20 to be dynamic
Make, by fictitious load access wireless receiving end, and battery-end is disconnected；
Optionally, processor 30 uses microcontroller.
Wireless transmitting terminals, for when fictitious load accesses wireless receiving end and battery-end disconnects, detecting itself circuit
State change information stops charging when state change information meets preset condition.
Specifically, increase voltage detecting circuit 10 at wireless receiving end, three states of battery charging are respectively that trickle fills
Electricity, constant-current charge and constant-voltage charge.When battery reaches constant-voltage charge, system power can be smaller, at this point, voltage detecting is electric
The information of voltage of battery-end is detected on road 10, and when the information of voltage is higher than predetermined threshold value, battery charging complete or needs will be electric
Pond disconnects, and the information of voltage detected is returned to processor 30, processor 30 controls fictitious load switching circuit 20 by fictitious load R
In incision system, at this time because output is terminated with battery pack, the voltage at the both ends fictitious load R is vised by cell voltage at this time, for electricity
Cell voltage.Since system is resistive load from capacitive load transfer, the state of wireless transmitting terminals itself circuit changes, root
It may determine that battery disconnects or battery charging complete prevents to which wireless transmitting terminals subjective can power off according to the state change
Device failure is caused in wireless receiving end since battery disconnects suddenly, or damages battery due to over-charging of battery.
Specifically, wireless transmitting terminals can judge the state at wireless receiving end by detecting the phase of voltage and current.Such as
Fruit voltage current phase difference is more than predetermined threshold value, then wireless transmitting terminals think that wireless receiving end-cell is full of or battery disconnects,
To subjective power-off, device and battery can be protected, realize the opened loop control of wireless power supply system.

Second switch K2 is controlled to disconnect.
Specifically, voltage detecting circuit 10 includes the voltage follower B and divider resistance R1 in parallel with battery-end and divides
Piezoresistance R2；Information of voltage between voltage follower B acquisitions R1 and R2, and the information of voltage between R1 and R2 is sent to place
Manage device 30.It is divided by R1, R2 resistance, by the voltage U between R1 and R2B(+)=R2/ (R1+R2) * Uout, pass through electricity
Pressure follower feeds back to processor 30, and processor distinguishes AD (Analogue to Digital) value of collection voltages follower, root
According to UBThe value of (+) and R1 and R2 can calculate the voltage of battery-end, and processor 30 is judged, if value of feedback is more than in advance
If value, then relay K1 is closed, by (this position resistance need to select power resistor), preset time in fictitious load incision system
After (such as 2S), K1 is disconnected, battery disconnects at this time.
As shown in figure 3, wireless power supply system uses LCL-LCL topological structures, the electric current on the inductance Lp of wireless transmitting terminals
Ip is calculated by formula (1)：
Ip=J (M/w*Lp*Ls) * Uout (1)
Wherein, J is twiddle factor；M is mutual inductance value；W is wireless power supply system angular frequency.
It can show that the size of the electric current Ip on LP is related with the output voltage Uout at wireless receiving end from formula (1),
So the output voltage at wireless receiving end changes when Uout, the electric current Ip on LP also changes.It is opened so working as second
K2 cut-outs are closed, are accessed in fictitious load R, and when battery disconnection, fictitious load R both end voltages are Uout, and Uout can be increased, IP
It can increase suddenly, at this point, wireless transmitting terminals may determine that the state at wireless receiving end is battery disconnection or battery charging complete.
Wireless transmitting terminals include inverter circuit, by system after fictitious load R access from capacitive load transfer be resistive load, nothing
The voltage current phase of line transmitting terminal inversion output also changes.Wireless transmitting terminals are used for when fictitious load access wireless receiving end
And when battery-end disconnects, the phase difference of the voltage and current of detection inverter circuit output stops when phase difference meets preset condition
Only charge.Preset condition is that phase difference is more than preset value and is Sudden Changing Rate.Wireless transmitting terminals think that wireless receiving end has been charged
At either battery-end failure disconnect, transmitting terminal disconnect main power source, no longer to receiving coil provide energy, to protect battery and
Receiving terminal device.
As shown in figure 4, the present embodiment additionally provides a kind of wireless power control using above-mentioned wireless power control device
Method includes the following steps：
Step S101 detects the information of voltage of battery-end；
Step S102, when the information of voltage of battery-end is higher than predeterminated voltage, by fictitious load access wireless receiving end, and will
The battery-end at wireless receiving end disconnects；
Step S103 detects the state change information of wireless transmitting terminals；
Step S104 stops charging when state change information meets preset condition.
Specifically, the phase difference for detecting the voltage and current of the inverter circuit output of wireless transmitting terminals, when the phase difference is more than
Preset value and be Sudden Changing Rate, wireless transmitting terminals think the charging complete of wireless receiving end either battery-end failure disconnect, transmitting
End disconnects main power source, no longer energy is provided to receiving coil, to protect battery and receiving terminal device.
