What deserves to be explained is, this electronic equipment also has control module; As a kind of execution mode, described control module adopts the existing controller of electronic equipment to realize; As another execution mode, add described control module in the electronic device, namely this control module is different from the existing controller of electronic equipment; As the specific implementation of described control module, the embodiment of the present invention does not limit, and processor, single-chip microcomputer or programmable logic device etc. can be adopted to have the circuit realiration of data processing function.
What deserves to be explained is, control module is electrically connected with each switch module, and being turned on or off by control module control switch module; Illustrate, when control module receives the turn-on command of conducting first switch module, control the power pins of the first switch module conducting charging inlet and the electrical connection of the first charging circuit; When control module receives the open command of disconnection first switch module, control the first switch module and disconnect the power pins of charging inlet and the electrical connection of the first charging circuit.It should be noted that, which electronic device is the embodiment of the present invention adopt realize to switch module, and the circuit connecting relation between this electronic device, all do not limit.

Specifically as shown in Figure 1, the workflow of this charging method of the embodiment of the present invention shown in Fig. 1.This charging method of the embodiment of the present invention comprises A1 and A2.
It should be noted that, as above-mentioned, described electronic equipment comprises charging inlet, N number of switch module, N number of charging circuit and battery core, in the charging process of described electronic equipment, charged electrical signal is successively through described charging inlet, a M described switch module, a M described charging circuit and described battery core, described M is less than or equal to N, and described M, N are positive integer.Wherein, for M described switch module, a charging circuit in its each switch module correspondence series connection M charging circuit.
A1, in the process of charging to battery core through the charging inlet of electronic equipment, a M switch module and M charging circuit successively, determines whether described first charging circuit is connected described first switch module with described battery core short circuit.Wherein, described charging circuit comprises described first charging circuit, and described switch module comprises described first switch module, described first switch module and described first charging circuit series connection.
Particularly, after power supply unit is electrically connected with the charging inlet of electronic equipment, under the power pins of charging inlet described in the conducting of M switch module difference and the state of M charging circuit, power supply unit charges to battery core through the charging inlet of electronic equipment, a M switch module and M charging circuit successively.In all charge circuits charged to battery core with the charging inlet of electronic equipment, a M switch module and M charging circuit, there is a charge circuit, this charge circuit is through the power pins of the charging inlet of connecting successively, the first switch module, the first charging circuit and battery core.
Wherein, because described M is positive integer, namely A1 can charge to battery core by least one charging circuit.When M is greater than 1, M charging circuit, in parallel to battery core charging, is shared the electric current charged to battery core by the charging circuit of parallel connection; Like this, the caloric value that each charging circuit brings because of electric energy loss can be reduced.
In addition, in the different charging stages of charging to battery core, control module can adjust M numerical value, and namely adjustment uses how many charging circuits to charge to battery core simultaneously.
As an Alternate embodiments, in the preliminary filling stage, control module determines that M is numerical value " 1 ", i.e. control module only conducting charging circuit, forms the charge circuit to battery core charging by this charging circuit.
As an Alternate embodiments, at constant-current charging phase, control module determines that M is numerical value " 2 ", i.e. control module conducting two charging circuits, form the charge circuit to battery core charging respectively by two charging circuits, two charging circuits charge to battery core parallelly simultaneously.
As an Alternate embodiments, at constant voltage charging phase, control module determines that M is numerical value " 1 ", i.e. control module only conducting charging circuit, forms the charge circuit to battery core charging by this charging circuit.
What deserves to be explained is, the embodiment of the present invention is in the process of charging to battery core, determine whether described first charging circuit is connected described first switch module with described battery core short circuit in real time, but to how determining that the specific implementation that the first switch module is connected with described battery core short circuit does not limit; Illustrate, detect the electric current flowing through the first charging circuit, if the electric current detected is greater than current threshold, represent that the first switch module is connected with battery core short circuit by the first charging circuit.
A2, when described first switch module is connected with described battery core short circuit by described first charging circuit, control the electrical connection that described first switch module disconnects described charging inlet and described first charging circuit, to stop being charged to battery core by described first charging circuit.
Particularly, the first switch module that the embodiment of the present invention provides is controlled by control module, particularly, is controlled conducting or the disconnection of the first switch module by control module; When control module controls the first switch module conducting, the power pins of the first switch module conducting charging inlet and the electrical connection of the first charging circuit; When control module controls the first switch module disconnection, the first switch module disconnects the power pins of charging inlet and the electrical connection of the first charging circuit.
In embodiments of the present invention, control module is once detect that described first switch module is connected with described battery core short circuit by described first charging circuit, control the electrical connection that the first switch module disconnects described charging inlet and described first charging circuit immediately, making to be disconnected the charge circuit that battery core is charged by the first charging circuit, stopping through charging to battery core to the first charging circuit; While disconnecting the charge circuit charged to battery core by the first charging circuit, if also there is other charge circuit to battery core charging, the charging circuit continued through in other charge circuit charges to battery core.
Preferably, when control module controls after the first switch module disconnects the charge circuit charged to battery core by the first charging circuit, control module reselects a charging circuit and substitutes this first charging circuit, charges to battery core through the charging circuit reselected.
A kind of optimized work flow of this charging method of the embodiment of the present invention shown in Fig. 2, for convenience of description, illustrate only the part relevant to the embodiment of the present invention.
As the embodiment of the present invention one Alternate embodiments, see Fig. 2, describedly determine whether described first charging circuit is connected described first switch module with described battery core short circuit, comprises A11 and A12.
A11, determines the voltage difference between the input of described first charging circuit and output.Wherein, the input of described first charging circuit and output correspondence are electrically connected with described first switch module and described battery core.
Particularly, voltage detecting circuit is provided with in electronic equipment, the voltage of the input of the first charging circuit is detected by this voltage detecting circuit, detected the voltage of the output of the first charging circuit by this voltage detecting circuit, control module calculates the voltage that detects from input and voltage difference between the voltage detected from output simultaneously.
Preferably, this voltage detecting circuit is located in control module; By the voltage of the input of the detection in real time first of the voltage detecting circuit in control module charging circuit, detect the voltage of the output of the first charging circuit simultaneously.
A12, when described voltage difference is less than voltage difference threshold value, determines that described first switch module is connected with described battery core short circuit by described first charging circuit.
Under normal circumstances, in the process that the first charging circuit charges to battery core, the signal of telecommunication introduced from input can be carried out step-down adjustment by the first charging circuit, adjusts the voltage be applicable to battery core charging, and from the voltage that output output adjusted goes out; Therefore, larger voltage difference can be there is between the input of the first charging circuit and output; Charging circuit itself also has a constant impedance in addition, also can cause the voltage difference that can exist between the input of the first charging circuit and output.
Therefore when present embodiment is normally charged to battery core according to the first charging circuit, voltage difference between the input of determined first charging circuit and output, sets described voltage difference threshold value.Therefore the voltage difference threshold value set is less than: voltage difference between the input of determined first charging circuit and output when the first charging circuit normally charges to battery core.
In addition, during because of the first charging circuit short circuit, between the input of the first charging circuit and output, voltage difference can be very little, goes to zero, so can set less by voltage difference threshold value, even close to zero.
It is emphasized that, the embodiment of the present invention supports that multiple charging circuit charges to battery core simultaneously, therefore, the embodiment of the present invention can carry out large current charge (large current charge of such as more than 3A) to battery core, also support high-voltage charge in addition, namely power supply unit can export the signal of telecommunication with 5V or more voltage to electronic equipment.Therefore, can there is larger voltage difference in the input of charging circuit and output.
Illustrate, at constant-current charging phase, for reducing loss, power supply unit exports the signal of telecommunication with 5V or more voltage to electronic equipment, the charging circuit of electronic equipment is to this signal of telecommunication step-down and improve electric current, multiple charging circuits in parallel charge to battery core simultaneously, and the charging current of simultaneously charging to battery core is 3A or more electric current.
Another optimized work flow of this charging method of the embodiment of the present invention shown in Fig. 3, for convenience of description, illustrate only the part relevant to the embodiment of the present invention.
As the embodiment of the present invention one Alternate embodiments, see Fig. 3, describedly determine whether described first charging circuit is connected described first switch module with described battery core short circuit, comprises A13 and A14.
A13, determines the electric current of described first charging circuit.
Particularly, in electronic equipment, be provided with current detection circuit, the electric current flowing through described charging circuit is detected in real time to current detection circuit in the process of battery core charging, and the Current Feedback Control module that will detect.Certainly, current detection circuit also detects the electric current of the first charging circuit in real time, and the Current Feedback Control module that will detect.
Preferably, this current detection circuit is located in control module, is detected the electric current flowing through described charging circuit by the current detection circuit in control module in real time.
A14, when described electric current is greater than current threshold, determines that described first switch module is connected with described battery core short circuit by described first charging circuit.
If the first charging circuit short circuit, the impedance of the first charging circuit is very little, and the impedance of other charging circuits is relatively large, causes the electric current flowing through the first charging circuit can become suddenly large.Therefore, charging current when normally charging to battery core according to the first charging circuit in advance, determines current threshold, and the current threshold determined is greater than: charging current when the first charging circuit normally charges to battery core.
Control module, once detect that the electric current flowing through the first charging circuit is greater than current threshold, can be judged to be described first charging circuit short circuit, and described first switch module is connected with described battery core short circuit by described first charging circuit of short circuit.

As the embodiment of the present invention one Alternate embodiments, see Fig. 4, described charging method also comprises A3, A4 and A5.
A3, sends the charging instruction of specifying charging voltage to described power supply unit.
Power supply unit described in present embodiment can be charging adapter, also can be other electronic equipment.But it should be noted that, when electronic equipment is connected with power supply unit, is by the charging inlet output charged electrical signal of power supply unit to electronic equipment, with this signal of telecommunication, the battery core of electronic equipment is charged.
In addition, power supply unit has controller, and after power supply unit is connected with electronic equipment, this controller can communicate with the control module of electronic equipment.The control module of electronic equipment can send charging adjustment signal (such as described charging instruction) to the controller of charging adapter, and the controller of power supply unit is according to the charging adjustment signal adjustment received: the voltage of power supply unit output and/or electric current and/or power.
As an Alternate embodiments, the control module of electronic equipment sends this charging instruction to the controller of charging adapter, and charging adapter exports the signal of telecommunication with the voltage that described charging instruction is specified to electronic equipment; Preferably, the voltage that described charging instruction is specified is more than or equal to 5V, such as 5V, 9V or 12V.
Such as, when charging adapter receives the charging instruction of electronic equipment transmission, if this charging instruction specifies 9V, then the controller of charging adapter judges whether that the voltage supporting 9V exports, if it is determined that for supporting, export the signal of telecommunication of 9V to the charging inlet of electronic equipment under the control of this controller.Under default situations, or this charging instruction voltage of specifying for 5V, 9V or 12V time, charging adapter exports the signal of telecommunication of 5V to the charging inlet of electronic equipment.
A4, receives the charging response that described power supply unit sends according to described charging instruction.
In the present embodiment, described power supply unit receives this charging instruction, and when judging to support to fill soon, the control module to electronic equipment feeds back charging response corresponding to described charging instruction.As present embodiment one case study on implementation, described power supply unit receives this charging instruction, and when being judged to not support to fill soon, is not feedback person does not support instruction to electronic equipment feedback to the control module of electronic equipment.
A5, according to described charging response, the charge circuit that a conducting K charging circuit charges to described battery core, wherein, described K is less than or equal to described N.
And then the charging corresponding with described charging instruction that described control module receives described power supply unit feedback responds, and generates the dispersion charging instruction of specifying K charging circuit.Control module selects K charging circuit according to this dispersion charging instruction, and the charge circuit that this K of conducting charging circuit charges to described battery core, this K charging circuit through parallel connection charges to described battery core.
As the embodiment of the present invention one Alternate embodiments, a kind of concrete optimization is cooked to A5, describedly determines, to the quantity K of the charging circuit that described battery core is charged, to comprise:
