And then cause by the magnitude of current of the output of data-interface to charging equipment to be first magnitude of current and the second magnitude of current sum.
For example：By performing extended instruction, the 4th pin 209 in by USB interface draws notebook computer with the 5th
While the transmission magnitude of current of foot 210 is the electric current of 1.8A, the first pin 201 controlled in USB interface is connected with the first power line 203
Connect, second pin 204 is connected with ground wire 206 so that USB interface transmits electric current of the magnitude of current for 1.8A to mobile phone, and then causes
The magnitude of current by the output of USB interface to mobile phone is 3.6A.
In order to being neatly first magnitude of current and the second electric current according to user operation or directly incoming output current
The charge mode of amount sum, step 301 are specifically included：Electronic equipment obtains the expansion of the current output for growth data interface
Exhibition operation, based on the extended operation of the current output for growth data interface, generates the electric current for growth data interface
The extended instruction of output, or carry out data transmission when electronic equipment is not used data-interface in the first preset time range
When, generate the extended instruction of the current output for growth data interface.
For example：During mobile phone charges, operation of the user by a current output for being used for growth data interface,
Notebook computer is obtained in that the extended operation of the current output for growth data interface, based on for growth data interface
Current output extended operation, generate the extended instruction of the current output for growth data interface.
Or user is in the first preset time range, such as when in 5 minutes, unused USB interface carries out data transmission, pen
Remember that this computer directly generates the extended instruction of the current output for growth data interface.
In order that data-interface can be switched to number by charge mode neatly, in time by the data-interface of electronic equipment
According to transmission mode, before extended instruction is performed, also including step：Detect whether that data need to transmit by data-interface；
When detecting no data and needing to transmit by data-interface, execution step 302 is needed by data when data have been detected
When interface is transmitted, the first pin 201 in control data interface is connected with the first data wire 202, and second pin 204 and second is counted
Connect according to line 205, for transmission data.
For example：Before notebook computer performs extended instruction, also detect whether that data need to pass by USB interface
It is defeated.
When user does not need notebook computer to carry out data transmission with mobile phone, notebook computer detects no data and needs
USB interface to be passed through, then the first switching switch in USB interface 207 turn on the first power line 203, by the in USB interface
One pin 201 is connected to the first power line 203, and the second switching switch 208 in USB interface is turned on ground wire 206, and USB is connect
Second pin 204 in mouthful is connected to ground wire 206, makes the first pin 201 transmit electricity of the magnitude of current for 1.8A with second pin 204
Stream, and then cause by the magnitude of current of the output of USB interface to mobile phone to be 3.6A.
When user needs to obtain the data stored in mobile phone by notebook computer, notebook computer has detected data
Need by USB interface, then in USB interface, the first switching switch 207 is turned on the first data wire 202, by the in USB interface
One pin 201 is connected to the first data wire 202, and the second switching switch 208 in USB interface is turned on the second data wire 205, will
Second pin 204 in USB interface is connected to the second data wire 205 so that notebook computer can pass through USB interface and mobile phone
Carry out data transmission, the data stored in obtaining mobile phone.
