Dump energy is then obtained by electric power detection unit 108 detection.Significantly, since the product class of each electronic equipment
Type, model are different, and the rechargeable battery of configuration is likely to difference, therefore, and above-mentioned performance parameter (charging voltage, the maximum electricity of charging
Stream, the current residual electricity of charged battery capacity, default charge threshold and rechargeable battery) for different electronic equipments
And there is different setting values.
Step S405, the bottom-up information obtained according to clearing house, it is greater than at the current residual electricity having at least one electronic equipment
In the case of default charge threshold, determine that unit determines that two electronics needing to perform charging operations set by mode of operation
Standby mode of operation.Described mode of operation includes charge mode and discharge mode.
In the present embodiment, electronic equipment, according to the bottom-up information of self, learns the information of self mode of operation available to execute.
Accordingly, on the one hand, exchange the information of self mode of operation available to execute at two electric rooms setting up communication connection and incite somebody to action
The information of described mode of operation is shown in described man-machine interface；On the other hand, according to the work available to execute of electronic equipment self
The information of operation mode provides the execution option of corresponding mode of operation in the man-machine interface of electronic equipment, need to perform for determining
Mode of operation.
It addition, determine the information of described mode of operation according to the bottom-up information of electronic equipment, including: if electronic equipment is current
When dump energy is more than or equal to described charge threshold, the most described electronic equipment mode of operation available to execute includes charge mode and puts
Power mode；If the current residual electricity of electronic equipment is less than described charge threshold, the work that the most described electronic equipment is available to execute
Pattern only includes charge mode.
Further, owing to two electronic equipments have different executable mode of operations according to respective bottom-up information.Determining
Need to perform, in the mode of operation of two electronic equipments of charging operations, to need to meet condition: the work of one of them electronic equipment
Operation mode is defined as charge mode, and the mode of operation of another electronic equipment is defined as discharge mode.Here, especially, if two
When the current residual electricity of individual electronic equipment is respectively less than respective described charge threshold, then the work that two electronic equipments are available to execute
Pattern the most only includes charge mode, it is impossible to perform corresponding charging operations, now, in the man-machine interface 104 of two electronic equipments
On can point out the information that the battery electric quantity of the other side is not enough, and other electronic equipment of recommended replacement.
Step S407, according to the mode of operation of two electronic equipments determined, performs charging operations.
In the present embodiment, step S407 specifically includes:
Unit determines the electronic equipment being operated under charge mode to utilize mode of operation to determine, utilizes microcontroller 112 to be filled inside
Electric unit 116 is opened, and unit determines that the electronic equipment being operated under discharge mode sends and prepared to utilizing mode of operation to determine
One-tenth information；
Determine that the electronic equipment being operated under discharge mode controls buck unit 118 according to the bottom-up information that clearing house obtains and performs liter
Step-down action, makes the output voltage of buck unit 118 adapt to determine the charged electrical of the electronic equipment being operated under charge mode
Pressure, and the maximum current that output maximum current adapts to need when determining the electronic equipment charging being operated under charge mode is set；
Determine that the electronic equipment being operated under discharge mode is receiving the standard determining that the electronic equipment being operated under charge mode is sent
After completing information, open discharge cell 120 and start the first electronic equipment is charged；
In charging process, determine the electronic equipment being operated under charge mode by the charged state immediate feedback of oneself give determine work
Make the electronic equipment under discharge mode.If it is determined that electronic equipment under being operated in discharge mode is operated under charge mode to determining
Electronic equipment charging time, determine the electricity that the determination that the electronic equipment being operated under discharge mode receives is operated under charge mode
Subset feedack is consistent with original state all the time or is not received by determining that the electronic equipment being operated under charge mode is anti-
The information of feedback, then interrupt charging process feedback error information.If in charging process, determine the electricity being operated under discharge mode
Subset detection obtains the current residual electricity of self rechargeable battery and is less than described charge threshold, then interrupt charging, and information is anti-
Feed and determine the electronic equipment being operated under charge mode, the man-machine interface of two electronic equipments is pointed out the battery electric quantity of the other side
Not enough information, and other electronic equipment of recommended replacement, complete charge operates；If it is determined that the electronics under being operated in charge mode
After the battery of equipment is full of, to the information determining that the electronic equipment feedback battery being operated under discharge mode is full of, determines and be operated in
Electronic equipment under discharge mode interrupts charging process according to feedack, completes charging.
