The electronic equipment that the embodiment of the present invention provides, this electronic equipment comprises charging inlet, switch module, charging circuit and battery core etc.Battery core is used for for power electronic equipment.Charging inlet, switch module, charging circuit and battery core are electrically connected successively.
What deserves to be explained is, the charging circuit that this electronic equipment comprises is N number of, described N be greater than 1 positive integer; N number of charging circuit is connected in parallel between switch module and battery core.As the embodiment of the present invention one Alternate embodiments, described charging circuit is the circuit be made up of electronic device.As the embodiment of the present invention one Alternate embodiments, described charging circuit is charging chip.
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 switch module, and being turned on or off by control module control switch module; Particularly, when control module receives turn-on command, the electrical connection of control switch module conducting charging inlet and charging circuit; When control module receives open command, control switch module disconnects the electrical connection of charging inlet and 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.Illustrate, switch module adopts metal-oxide-semiconductor to realize; The grid of metal-oxide-semiconductor, source electrode and drain electrode connect control module, the power pins of charging inlet and each charging circuit respectively; Control module controls the electrical connection of whether conducting charging inlet and charging circuit by the level signal controlling to export to the grid of metal-oxide-semiconductor.
What deserves to be explained is, control module is also electrically connected with each charging circuit (i.e. N number of charging circuit) respectively, and whether control module can control to charge to battery core through certain charging circuit.Such as, when control module receives dispersion charging instruction, control module only disperses charging instruction to specify multiple charging circuits described in conducting, multiple charging circuit actuating switch module of being specified by described dispersion charging instruction and the electrical connection of battery core, only form the charge circuit that multiple charging circuits that described dispersion charging instruction specifies charge to battery core.
As stated in the Background Art, when battery core being charged by charging circuit, may because of this charging circuit short circuit, the voltage of the signal of telecommunication that power supply unit is exported directly is imposed in battery core through the charging circuit of short circuit, damages battery core, even causes battery core to burst.Therefore, the embodiment of the present invention has been connected a switch module between charging circuit and the power pins of charging inlet, if certain charging circuit short circuit, directly can control this switch module and disconnect the charge circuit that all charging circuits charge to battery core, stop charging to battery core.
It should be noted that, the charging inlet of electronic equipment comprises data pin; After electronic equipment is connected with power supply unit by its charging inlet, electronic equipment carries out transfer of data by this data pin and power supply unit, the data can transmitted by this data pin are not limited to and relevant data of charging, all right transmission tone video file, document files etc. data.
Particularly, the workflow of this charging method of the embodiment of the present invention shown in Fig. 1, but for convenience of description, illustrate only the part relevant to the embodiment of the present invention.This charging method of the embodiment of the present invention comprises A1 and A2.
It should be noted that, in the charging process of described electronic equipment, charged electrical signal is successively through described charging inlet, described switch module, a M described charging circuit and described battery core, and described M is less than or equal to N, and described M is positive integer.Particularly, power supply unit exports charged electrical signal to electronic equipment, and this charged electrical signal through described charging inlet, described switch module, M described charging circuit in parallel and described battery core, charges to described battery core with this charged electrical signal successively.
A1, in the charging process of described electronic equipment, determines whether described charging circuit is connected described switch module with described battery core short circuit.
Particularly, after power supply unit is electrically connected with the charging inlet of electronic equipment, under the power pins of charging inlet described in switch module conducting and the state of one or more charging circuit, power supply unit charges to battery core through the charging circuit of the charging inlet of electronic equipment, switch module and M parallel connection successively.
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, the charging circuit of M, in parallel to battery core charging, is shared the electric current charged to battery core by M 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 the numerical value of M, and namely adjustment uses how many charging circuits simultaneously to battery core charging, illustrates as follows:
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;
At constant-current charging phase, control module determines that M is numerical value " 2 ", i.e. control module conducting two charging circuits, and 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, 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, to how determining whether described charging circuit was connected described switch module with described battery core short circuit, the embodiment of the present invention, in the process of charging to battery core, specifically determines that mode does not limit.
Mode is determined as determine whether described charging circuit be connected described switch module with described battery core short circuit one, whether the described charging circuit of real-time detection is connected described switch module with described battery core short circuit, but does not limit the specific implementation how sense switch module is connected with described battery core short circuit;
Illustrate, detect the electric current flowing through charging circuit, if the electric current detected is greater than current threshold, represent that switch module is connected with battery core short circuit by charging circuit; Illustrate again, at constant voltage charging phase, detect the voltage of the signal of telecommunication that charging circuit exports to battery core, if the voltage detected is greater than battery core voltage in the saturated condition (i.e. the voltage of battery core under full state), represent that switch module is connected with battery core short circuit by charging circuit.
A2, when described switch module is connected with described battery core short circuit by described charging circuit, controls the electrical connection that described switch module disconnects described charging inlet and described charging circuit, to stop being charged to battery core by described charging circuit;
Particularly, the switch module that the embodiment of the present invention provides is controlled by control module, particularly, by conducting or the disconnection of control module control switch module; When the module conducting of control module control switch, the power pins of conducting charging inlet and the electrical connection of charging circuit; When control module control switch module disconnects, disconnect the power pins of charging inlet and the electrical connection of charging circuit.
In embodiments of the present invention; control module is once detect that described switch module is connected with described battery core short circuit by described charging circuit; control switch module disconnects the electrical connection of described charging inlet and described charging circuit immediately; make all to be disconnected the charge circuit that battery core is charged by arbitrary charging circuit; stop battery core charging, protection battery core.
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 switch module with described battery core short circuit, comprises A11 and A12.
A11, determines the voltage in the power pins of described charging inlet;
A12, when the voltage in described power pins is less than or equal to the first voltage threshold, determines that described switch module is connected with described battery core short circuit by described charging circuit.
To the voltage how determined in the power pins of described charging inlet, present embodiment specifically determines that mode does not limit.As an implementation, voltage detecting circuit is provided with in electronic equipment, this voltage detecting circuit is electrically connected with the power pins of charging inlet, detects the voltage of the power pins of charging inlet in real time to voltage detecting circuit in the process of battery core charging, and the Voltage Feedback control module that will detect.Preferably, this voltage detecting circuit is located in control module, is detected the voltage of the power pins of charging inlet by the voltage detecting circuit in control module in real time.
Under normal circumstances, the charging voltage that battery core can bear is certain, and the voltage of the signal of telecommunication that power supply unit exports to electronic equipment is greater than the charging voltage that battery core can bear, if charging circuit short circuit, the voltage that power supply unit exports can directly be imposed in battery core, the voltage that power supply unit exports can directly be imposed in battery core, and whether battery core is full of all is charged by force to battery core, damages battery core.
In addition, if charging circuit short circuit, because battery core is directly electrically connected with the power pins of charging inlet through the charging circuit of short circuit, the switch module of conducting, the voltage of the power pins of charging inlet can directly drag down by the voltage of battery core, causes the power pins of charging inlet significantly to reduce.Therefore, the voltage that present embodiment has been rushed according to battery core under the different charging stage determines described first voltage threshold, the voltage that described first voltage threshold determined has rushed higher than battery core, determines this first voltage threshold according to experimental datas such as the impedances of the internal circuit of switch module during embody rule.
Illustrate, at constant voltage charging phase, the first voltage threshold determined is greater than the voltage of battery core under full state.
In addition, battery core, under full state, also determines the first voltage threshold, and the first voltage threshold determined is greater than the voltage of battery core under full state.Like this, when battery core is full of, if charging circuit short circuit, fail to disconnect the charge circuit to battery core charging; Power supply unit can be greater than the voltage of battery core under full state through the charging circuit voltage forced in battery core of short circuit, by force battery core is charged, the voltage of charging inlet power source pin also can be dragged down by the voltage of battery core simultaneously, cause the voltage in this power pins to be less than described first voltage threshold, the condition provided is provided.
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 charging circuit is connected described switch module with described battery core short circuit, comprises A13 and A14.
A13, determines the voltage of described battery core;
A14, when the voltage of described battery core is more than or equal to the second voltage threshold, determines that described switch module is connected with described battery core short circuit by described charging circuit.
In the present embodiment, in electronic equipment, be provided with voltage detecting circuit, the voltage of battery core is detected in real time to voltage detecting circuit in the process of battery core charging, and the Voltage Feedback control module that will detect.Preferably, this voltage detecting circuit is located in control module, is detected the voltage of battery core by the voltage detecting circuit in control module in real time.
Under normal circumstances, the charging voltage that battery core can bear is certain, if the voltage of the signal of telecommunication that power supply unit exports to electronic equipment is greater than the charging voltage that battery core can bear, such as charging circuit short circuit, the voltage that power supply unit exports can directly be imposed in battery core, whether battery core is full of all is charged by force to battery core, damages battery core.
Therefore, the upper limit of the charging voltage that present embodiment can bear in the different charging stage according to battery core determines described second voltage threshold, and this second voltage threshold determined is greater than the charging voltage that battery core can bear.
Illustrate, at constant voltage charging phase, the second voltage threshold determined is greater than the voltage of battery core under full state.
In addition, in battery core under full state, also determine the second voltage threshold, the second voltage threshold determined is greater than the voltage of battery core under full state.Like this, when battery core is full of, if charging circuit short circuit, but do not disconnect the charge circuit to battery core charging yet; Power supply unit can be greater than the voltage of battery core under full state through the charging circuit voltage forced in battery core of short circuit, and the voltage forced in battery core can reach the second voltage threshold, meets the condition provided.
What need were strong is, 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.
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. 4, 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. 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.
