See Fig. 1, the method for supplying power to that the embodiment of the present invention provides comprises A1 and A2.
A1, determines the voltage of described data pin.
Particularly, control module is electrically connected with the data pin of charging inlet; Receive the signal of telecommunication being loaded with data sent by power supply unit from this data pin, first control module can detect the signal of telecommunication being loaded with data, the voltage of this signal of telecommunication namely detected, parses data according to this voltage.When control module detects the voltage of this signal of telecommunication, whether the voltage first comparing this signal of telecommunication exceeds the first voltage threshold, and only when the voltage of this signal of telecommunication belongs in this first voltage threshold, ability is normal parses data from this signal of telecommunication; If the voltage of this signal of telecommunication does not belong in this first voltage threshold, not only abandon parsing data from this signal of telecommunication, also perform A2.

Accordingly, if the voltage comparing this signal of telecommunication by control module exceeds the first voltage threshold, then control module control switch module disconnects the electrical connection of data pin in described charging inlet and control module to a kind of execution mode in concrete and A1.
Another execution mode specifically and in A1 accordingly, if the voltage being compared this signal of telecommunication by switch module exceeds the first voltage threshold, then when the voltage that switch module compares this signal of telecommunication exceeds the first voltage threshold, disconnected the electrical connection of data pin in described charging inlet and control module immediately by switch module.
A kind of optimized work flow of this method of supplying power to 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, the described voltage determining described data pin, comprising: A11 and A12.
A11, determine the electrical connection of the power supply interface of described power supply unit and described charging inlet by disconnection be converted to be connected time, determine the voltage of described data pin.
Particularly, because of the moment of the electrical connection of the described charging inlet at the power supply interface and electronic equipment of setting up power supply unit, the surge voltage of moment can be produced; This surge voltage may exceed the first voltage threshold.Therefore, present embodiment is circuit or the control module of charging inlet rear class in protection electronic equipment, detects this surge voltage; If the voltage detected is more than or equal to the first voltage threshold, perform A2.
Such as, if set up the electrical connection of the power supply interface of power supply unit and the described charging inlet of electronic equipment by inserting mode, then in grafting moment, the data pin of charging inlet can produce surge voltage.
A12, determine the electrical connection of the power supply interface of described power supply unit and described charging inlet by be connected be converted to disconnection time, determine the voltage of described data pin.
Particularly, because of the moment of the electrical connection at the disconnection power supply interface of power supply unit and the described charging inlet of electronic equipment, the surge voltage of moment can be produced; This surge voltage may exceed the first voltage threshold.Therefore, present embodiment is circuit or the control module of charging inlet rear class in protection electronic equipment, detects this surge voltage; If the voltage detected is more than or equal to the first voltage threshold, perform A2.
Such as, if disconnected the electrical connection of the power supply interface of power supply unit and the described charging inlet of electronic equipment by pluggable mode, then pulling out instantaneously, the data pin of charging inlet can produce surge voltage.
As the embodiment of the present invention one Alternate embodiments, described first voltage threshold is determined by the input voltage of described power pins.
In the present embodiment, for the signal of telecommunication accessed from power pins, just for control module is powered after all needing to carry out step-down, if this power pins is directly electrically connected with the data terminal of control module, the internal circuit of control module directly can be burnt.For this reason, present embodiment, according to the input voltage from described power pins, determines that a relatively little voltage is as described first voltage threshold, or can using the input voltage of described power pins as described first voltage threshold.
As present embodiment one case study on implementation, this step of voltage of data pin in described detection charging inlet, specifically comprises: whether short circuit is connected to detect data pin and power pins in described charging inlet.
Particularly, at least with the voltage of 5 volts to power electronic equipment (comprise in electronic equipment battery core charging); Especially, when quick charge supported by power supply unit, the voltage of the signal of telecommunication that power supply unit exports to electronic equipment is greater than 5 volts.The signal of telecommunication exported to the power pins of charging inlet in electronic equipment because of power supply unit at least has 5 volts of voltages.If the data pin in charging inlet is connected with power pins short circuit, the voltage of data pin is pulled up to 5 volts or more, very easily burns the late-class circuit (comprising control module) be electrically connected with data pin.
Therefore, present embodiment carries out to data pin in charging inlet and power pins the detection whether short circuit is connected in real time, once detect that in charging inlet, data pin is connected with the short circuit of power pins, performs A2 immediately, disconnect the electric connection of described data pin and late-class circuit.
A kind of workflow of this method of supplying power to 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, described 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, a described K charging circuit belongs to all or part of charging circuit of described electronic equipment, and namely 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, do a kind of concrete optimization to A5, before the charge circuit that a described conducting K charging circuit charges to battery core, described method also comprises:
Determine the described electronic equipment current residing charging stage;
According to the current residing charging stage, determine the quantity K to the charging circuit that described battery core is charged.
As above-mentioned, the charging stage comprises preliminary filling stage, constant-current charging phase and constant voltage charging phase.Because of the different charging stage, the charging current that battery core can bear is different, and present embodiment is at the data K of different charging stage adjustment charging circuit.
Illustrate, in the preliminary filling stage, a charging circuit is enough to provide the charging current of described battery core needed for the preliminary filling stage, and control module determines that M is numerical value " 1 "; Control module is conducting charging circuit only, forms the charge circuit to battery core charging by this charging circuit;
At constant-current charging phase, two charging circuits are enough to provide described battery core in the charging current needed for 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;
At constant voltage charging phase, a charging circuit is enough to provide the charging current of described battery core needed for 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.
As a kind of embodiment to the method described in Fig. 3, described method also comprises:
Determine the quantity M to the charging circuit that described battery core is charged;
The charge circuit that a conducting M charging circuit charges to battery core, wherein, a described M charging circuit belongs to all or part of charging circuit of described electronic equipment, and wherein, described K is different from described M.
Particularly, A3 is to after described power supply unit sends the charging instruction of specifying charging voltage, if this power supply unit does not support to export the charging voltage that this charging instruction is specified, then this power supply unit can not to electronic equipment feedback charging response; Correspondingly, the control module in electronic equipment does not receive this charging response in preset time period, and determines data M.Then, control module selects M charging circuit from N number of charging circuit, and M the charging circuit that conducting is selected charges to this battery core simultaneously.
As a concrete case of present embodiment, described M is different from described K; Like this, control module, when not receiving the charging corresponding with this charging instruction and responding, is not supported to charge to battery core with K charging circuit simultaneously.
Such as, the charging voltage that this charging instruction is specified is high pressure, if power supply unit support exports this high pressure, then electronic equipment needs the number of charging circuit in parallel to be at least K, and described K is greater than described M.Namely need K charging circuit in parallel simultaneously to battery core charging, share charging current by K charging circuit; The number of charging circuit is less than K and cannot bears charging current, easily damages charging circuit.
Again such as, the charging voltage that this charging instruction is specified is low pressure, if power supply unit support exports this low pressure, then electronic equipment needs the number of charging circuit in parallel to be at most K, and described K is less than or equal to described M.Namely need K charging circuit in parallel simultaneously to battery core charging, share charging current by K charging circuit; The number of charging circuit reaches K and can bear charging current, so need more charging circuit, many charging circuit work can bring power loss.
As a concrete case of present embodiment, described M equals described K; Namely no matter whether described power supply unit supports to export the charging voltage that described charging instruction specifies, and control module is control K charging circuit conducting all, and while is charged to battery core by K charging circuit of parallel connection.
As the embodiment of the present invention one Alternate embodiments, describedly determine, to the quantity M of the charging circuit that described battery core is charged, to comprise:
According at least one in following parameter, determine the quantity M to the charging circuit that described battery core is charged:
