S101, the first equipment are detected after USB interface is connected with the second equipment, it is determined that needing to be filled for the second equipment
Electricity.
S102, the first equipment set in the first data wire and the second data wire short circuit in detecting USB interface to second
More than the electric current of first threshold, the first threshold is that the type based on the USB interface pre-sets for standby output.
First equipment is after detecting and being connected with the second equipment by USB interface, it is determined that need during for the second equipment charge,
The first data wire and the second data wire in USB interface can be carried out short circuit, to realize that the first equipment is big to the output of the second equipment
In the electric current of first threshold, that is, realize the first equipment to the second equipment quick charge.In above-mentioned steps S102, the first equipment exists
When detecting the first data wire and the second data wire short circuit in USB interface, the electricity to the output of the second equipment more than first threshold
During stream, when usb type is USB2.0, now, first threshold can be 500mA, i.e., when usb type is USB2.0
When, the first equipment, can be big to the output of the second equipment in the first data wire and the second data wire short circuit in detecting USB interface
In the electric current of 500mA；When usb type is USB3.0, now, first threshold can be 900mA, i.e., when USB interface class
When type is USB3.0, the first equipment, can be to second in the first data wire and the second data wire short circuit in detecting USB interface
Equipment electric current of the output more than 900mA.
Optionally, it is easier to charge in order that obtaining equipment room, USB interface can also be OTG interfaces (On-The-Go, a key
Copy).
Optional first equipment can be terminal, and the first equipment can also be personal computer PC.When the first equipment is for eventually
During end, the second equipment can also be terminal, and when the first equipment is personal computer PC, the second equipment can also be terminal.
When USB interface is OTG interfaces, and the first equipment and the second equipment are when being terminal, when the first equipment passes through OTG
After interface is connected with the second equipment, whether the first equipment can be grounded by the ID pins detected in OTG interfaces, judge whether needs
Be the second equipment charge, i.e., when the ID pins that the first equipment is detected in OTG interfaces are grounded, can be true according to host negotiation protocol
Fixed first equipment needs to be the second equipment charge, otherwise, it determines the first equipment need not be the second equipment charge.
ID pins ground connection in the first equipment detects OTG interfaces, it is the second equipment charge to determine that the first equipment needs
When, the first equipment can be indicated according to self-operating state or according to user, it is determined that the first data wire in the OTG interfaces with
When second data wire does not have data transfer, the first data wire and the second data wire are carried out into short circuit, with realize the first equipment to
Electric current of the second equipment output more than first threshold.
Used as a kind of implementation method, during user uses the first equipment, user can be by the menu of the first equipment
" quickly being charged to charging equipment " pattern is opened or closed, so that the first equipment is indicated according to user, by the first data
Line and the second data wire carry out short circuit, to realize electric current of first equipment to the output of the second equipment more than first threshold, so that real
Existing first equipment is to the second equipment quick charge.
As a kind of implementation method, after the first equipment is connected by OTG interfaces with the second equipment, and when the first equipment
When detecting the ID pins ground connection in OTG interfaces, the first equipment can also be determined the need for according to the electricity service condition of itself
First data wire in OTG interfaces and the second data wire are carried out into short circuit, so as to the electricity to the output of the second equipment more than first threshold
Stream.
Specifically, after the first equipment is connected by OTG interfaces with the second equipment, and when the first equipment detects OTG
When ID pins in interface are grounded, the first equipment can detect the electricity of itself, when the electricity that the first equipment detects itself is higher than
During Second Threshold, the first data wire in OTG interfaces and the second data wire are carried out into short circuit automatically, and when the first equipment is detected certainly
When the electricity of body is less than five threshold values, the automatic short circuit for disconnecting the first data wire and the second data wire in OTG interfaces.
For example, the first equipment is mobile phone A, the second equipment is mobile phone B, and mobile phone A and mobile phone B carried out by OTG interfaces
During connection, mobile phone A detects ID pins ground connection in OTG interfaces, and the ID pins that mobile phone B is detected in OTG interfaces are hanging, because
This, according to host negotiation protocol, it may be determined that mobile phone A is main frame, mobile phone B is peripheral hardware, i.e., mobile phone A can be charged for mobile phone B,
And when mobile phone A detects the electricity of itself higher than 60%, mobile phone A can be by by the first data wire of OTG interfaces and second
Data wire carries out short circuit, to realize mobile phone A as mobile phone B quick charge, and works as mobile phone A and detects the electricity of itself less than 10%

Flow for mobile phone B charges.
Because when terminal is in standby mode, now the power consumption of terminal only has ten a few to tens of milliamperes, and works as terminal and exist
Connection Wi-Fi (Wireless Fidelity, wireless emulation) networks or viewing HD video or connection 4G (the 4th
Generation communication system, forth generation communication system) network play big game when, power consumption can reach several
Hundred milliamperes, therefore, after the first equipment is connected by OTG interfaces with the second equipment, and when the first equipment detects OTG interfaces
In ID pins be grounded when, the first equipment can be also determined the need for the first data wire in OTG interfaces according to the power consumption of itself
Short circuit is carried out with the second data wire, so as to the electric current to the output of the second equipment more than first threshold.
Specifically, after the first equipment is connected by OTG interfaces with the second equipment, and when the first equipment detects OTG
When ID pins in interface are grounded, the first equipment also can detect the power consumption of itself, when the first equipment detects the low in energy consumption of itself
When three threshold values, the first data wire and the second data wire in OTG interfaces are carried out into short circuit automatically, and when the detection of the first equipment
When to the power consumption of itself being higher than six threshold values, the automatic short circuit for disconnecting the first data wire and the second data wire in OTG interfaces.
For example, the first equipment is mobile phone C, the second equipment is mobile phone D, and mobile phone C and mobile phone D carried out by OTG interfaces
During connection, mobile phone C detects ID pins ground connection in OTG interfaces, and the ID pins that mobile phone D is detected in OTG interfaces are hanging, because
This, according to host negotiation protocol, it may be determined that mobile phone C is main frame, mobile phone D can be charged for peripheral hardware, i.e. mobile phone C for mobile phone D,
When mobile phone C detects the power consumption of itself less than 100 MAHs, mobile phone C can be by by the first data wire of OTG interfaces and second
Data wire carries out short circuit, to realize mobile phone C as mobile phone D quick charges, and works as mobile phone C and detects the power consumption of itself higher than 500 millis
Ampere-hour, mobile phone C disconnects the first data wire of OTG interfaces and the short circuit of the second data wire, so that allowed based on charge protocol
Electric current is that mobile phone D charges, and works as mobile phone C and detect the power consumption of itself again less than 100 MAHs, and mobile phone C can be by by OTG
First data wire and the second data wire of interface carry out short circuit, are again mobile phone D quick charges.
Again because the temperature of terminal is a parameter of easy measurement, therefore, when the first equipment passes through OTG interfaces and second
After equipment connection, and when the first equipment detects ID pins in OTG interfaces and is grounded, the first equipment can also according to itself
Temperature determines the need for for the first data wire in OTG interfaces and the second data wire carrying out short circuit, so as to be exported to the second equipment
More than the electric current of first threshold.
Specifically, after the first equipment is connected by OTG interfaces with the second equipment, and when the first equipment detects OTG
When ID pins in interface are grounded, the first equipment also can detect the temperature of itself, when the temperature that the first equipment detects itself is low
When four threshold values, the first data wire and the second data wire in OTG interfaces are carried out into short circuit automatically, and when the detection of the first equipment
When to the temperature of itself being higher than four threshold values, the automatic short circuit for disconnecting the first data wire and the second data wire in OTG interfaces.
For example, the first equipment is mobile phone E, the second equipment is mobile phone F, and mobile phone E and mobile phone F carried out by OTG interfaces
During connection, mobile phone E detects ID pins ground connection in OTG interfaces, and the ID pins that mobile phone F is detected in OTG interfaces are hanging, because
This, according to host negotiation protocol, it may be determined that mobile phone E is main frame, mobile phone F can be charged for peripheral hardware, i.e. mobile phone E for mobile phone F,
When mobile phone E detects the temperature of itself less than 40 DEG C, mobile phone E can be counted by by the first data wire of OTG interfaces and second
Short circuit is carried out according to line, to realize mobile phone E quickly for mobile phone F charges, and when mobile phone E detects the temperature of itself higher than 40 DEG C,
Mobile phone E disconnects the first data wire of OTG interfaces and the short circuit of the second data wire, so as to be based on the electric current that charge protocol is allowed
Mobile phone F charges, and when mobile phone E detects the temperature of itself less than 40 DEG C again, and mobile phone E can be by by the of OTG interfaces
One data wire and the second data wire carry out short circuit, are again mobile phone F quick charges.
It should be noted that when the first equipment be personal computer PC, the second equipment be terminal when, by the second equipment according to
User indicates, and the first data wire and the second data wire in USB interface are carried out into short circuit, i.e. terminal indicates according to user, with reality
