It is worth noting that the charging circuit that the electronic equipment includes is N number of, the N is the positive integer more than 1;It is N number of to fill Electric circuit in parallel is between switch module and battery core.As one optional embodiment of the embodiment of the present invention, the charging circuit is The circuit being made of electronic device.As one optional embodiment of the embodiment of the present invention, the charging circuit is charging chip.

It is worth noting that the electronic equipment also has control module;As an implementation, the control module is adopted It is realized with the existing controller of electronic equipment;As another embodiment, add the control module in the electronic device, i.e., The control module is different from the existing controller of electronic equipment;As the specific implementation of the control module, the present invention is real It applies example not limit, it is real that the circuit with data processing function such as processor, microcontroller or programmable logic device may be used It is existing.

It is worth noting that control module is electrically connected with switch module, and the conducting of switch module is controlled by control module Or it disconnects;Specifically, when control module receives turn-on command, control switch module conducting charging interface and charging circuit Electrical connection;When control module receives open command, control switch module disconnection charging interface is electrically connected with charging circuit. It should be noted that the embodiment of the present invention uses switch module in the circuit between which electronic device realization and the electronic device Connection relation does not limit.For example, switch module is realized using metal-oxide-semiconductor;The grid of metal-oxide-semiconductor, source electrode and drain electrode difference Connect control module, the power pins of charging interface and each charging circuit;Control module is exported by control to the grid of metal-oxide-semiconductor Level signal control whether being electrically connected for conducting charging interface and charging circuit.

It is worth noting that control module is also electrically connected with each charging circuit (i.e. N number of charging circuit) respectively, mould is controlled Block can control whether to charge to battery core by some charging circuit.For example, when control module receives dispersion charging instruction, control The specified multiple charging circuits of the dispersion charging instruction are only connected in molding block, are specified by the dispersion charging instruction multiple Charging circuit conducting switch module is electrically connected with battery core, only forms the specified multiple charging circuits pair of the dispersion charging instruction The charge circuit of battery core charging.

It as stated in the background art, may be because of charging circuit short circuit so that power supply when being charged to battery core by charging circuit The charging circuit that the voltage of the electric signal of equipment output is directly over short circuit is imposed in battery core, is damaged battery core, is even resulted in electricity Core is burst.Therefore, the embodiment of the present invention has been connected a switch module between power pins of the charging circuit with charging interface, If some charging circuit is short-circuit, the switch module can be directly controlled and disconnect the charging time that all charging circuits charge to battery core Road stops charging to battery core.

It should be noted that the charging interface of electronic equipment includes data pin;Electronic equipment passes through its charging interface and confession After electric equipment connection, electronic equipment can be carried out data transmission by the data pin with power supply unit, can by the data pin The data of transmission are not limited to and the relevant data of charging, can also transmit audio-video document, document files etc. data.

Specifically, the workflow of the charging method of the embodiment of the present invention shown in Fig. 1, but for ease of description, only show Go out and the relevant part of the embodiment of the present invention.The charging method of the embodiment of the present invention includes A1 and A2.

It should be noted that in the charging process of the electronic equipment, charging electric signal pass through successively the charging interface, The switch module, the M charging circuits and the battery core, the M are less than or equal to N, and the M is positive integer.Specifically, Power supply unit exports charging electric signal to electronic equipment, which passes through the charging interface, the switching molding successively Block, the M charging circuit in parallel and the battery core, charge to the battery core with the charging electric signal.

Whether A1 determines the charging circuit by the switch module and institute in the charging process of the electronic equipment State battery core short circuit connection.

Specifically, after power supply unit is electrically connected with the charging interface of electronic equipment, the charging is connected in switch module For the power pins of interface in the state of one or more charging circuits, power supply unit passes through the charging of electronic equipment successively The charging circuit in parallel of mouth, switch module and M charges to battery core.

Wherein, because the M is positive integer, i.e. A1 can charge to battery core at least one charging circuit.When M is more than 1, M Charging circuit charge in parallel to battery core, the electric current to charge to battery core is shared by M charging circuit in parallel;In this way, can drop The calorific value that low each charging circuit is brought by electric energy loss.

In addition, in the different charging stages charged to battery core, control module can adjust the numerical value of M, i.e. adjustment uses more Few charging circuit simultaneously charges to battery core, is illustrated below:

In charging stage, control module determines that M is numerical value " 1 ", i.e. a charging circuit is only connected in control module, by this A charging circuit forms the charge circuit to charge to battery core;

In constant-current charging phase, control module determines that M is numerical value " 2 ", i.e. two charging circuits are connected in control module, pass through Two charging circuits are respectively formed the charge circuit to charge to battery core, and the parallel ground of two charging circuits simultaneously charges to battery core;

In constant voltage charging phase, control module determines that M is numerical value " 1 ", i.e. a charging circuit is only connected in control module, leads to It crosses this charging circuit and forms the charge circuit to charge to battery core.

It is worth noting that the embodiment of the present invention is during charging to battery core, to how to determine the charging circuit Whether the specific method of determination that the switch module is connect with the battery core short circuit is not limited.

As the determination charging circuit whether the method for determination for connecting the switch module with the battery core short circuit, Detect whether the charging circuit connect the switch module with the battery core short circuit in real time, but to how detection switch module The specific implementation being connect with the battery core short circuit does not limit;

For example, the electric current of detection stream overcharge circuit indicates charging if the electric current detected is more than current threshold Switch module is connect by circuit with battery core short circuit;Again for example, in constant voltage charging phase, detection charging circuit is defeated to battery core The voltage of the electric signal gone out, if the voltage detected is more than the voltage of battery core in the saturated condition, (i.e. battery core is having been filled with shape Voltage under state), indicate that switch module is connect by charging circuit with battery core short circuit.

A2 controls the switch module when the switch module is connect by the charging circuit with the battery core short circuit Being electrically connected for the charging interface and the charging circuit is disconnected, to stop through the charging circuit to battery core charging;

Specifically, switch module provided in an embodiment of the present invention is controlled by control module, specifically, is controlled by control module Switch module is switched on or off;When control module control switch module conducting, be connected the power pins of charging interface with The electrical connection of charging circuit;When control module control switch module disconnects, the power pins and charging electricity of charging interface are disconnected The electrical connection on road.

In embodiments of the present invention, control module once detect the charging circuit by the switch module with it is described Battery core short circuit connects, and switch module is immediately controlled and disconnects being electrically connected for the charging interface and the charging circuit so that passes through Any charging circuit is all disconnected the charge circuit that battery core charges, and stops charging to battery core, protects battery core.

Fig. 2 shows a kind of optimized work flow of the charging method of the embodiment of the present invention only show for ease of description With relevant part of the embodiment of the present invention.

As one optional embodiment of the embodiment of the present invention, referring to Fig. 2, whether determination first charging circuit will The switch module is connect with the battery core short circuit, including A11 and A12.

A11 determines the voltage in the power pins of the charging interface;

A12 determines that the charging circuit will when the voltage in the power pins is less than or equal to first voltage threshold value The switch module is connect with the battery core short circuit.

The specific method of determination of voltage in power pins of the present embodiment to how to determine the charging interface is not done It limits.As a realization method, voltage detecting circuit, the power supply of the voltage detecting circuit and charging interface are equipped in electronic equipment Pin is electrically connected, and voltage detecting circuit detects the voltage of the power pins of charging interface in real time during charging to battery core, and The Voltage Feedback control module that will be detected.Preferably, which is set in control module, by control module Voltage detecting circuit detect in real time charging interface power pins voltage.

Under normal circumstances, the charging voltage that battery core can bear is certain, and power supply unit is exported to electronic equipment The voltage of electric signal be greater than the charging voltage that battery core can bear, if charging circuit is short-circuit, the electricity of power supply unit output Pressure can be directly imposed in battery core, and the voltage of power supply unit output can be directly imposed in battery core, and no matter whether battery core is full of all It is charged by force to battery core, damages battery core.

In addition, if charging circuit is short-circuit, because battery core be directly over the charging circuit of short circuit, conducting switch module with fill The power pins of electrical interface are electrically connected, and the voltage of battery core can cause to fill directly by the voltage pull-down of the power pins of charging interface The power pins of electrical interface are greatly reduced.Therefore, present embodiment is determined according to the voltage that battery core has been rushed under the different charging stages The first voltage threshold value, the first voltage threshold value determined are higher than the voltage that has rushed of battery core, according to switch when concrete application The experimental datas such as the impedance of the internal circuit of module determine the first voltage threshold value.

For example, in constant voltage charging phase, determining first voltage threshold value is more than electricity of the battery core under the state that has been filled with Pressure.

In addition, battery core under the state that has been filled with, also determines first voltage threshold value, determining first voltage threshold value is more than electricity Voltage of the core under the state that has been filled with.In this way, when battery core has been filled with, if charging circuit is short-circuit, fails to disconnect and battery core is filled The charge circuit of electricity;Charging circuit of the power supply unit by short circuit, which forces the voltage in battery core, to have been filled with shape more than battery core Voltage under state by force charges to battery core, while the voltage of power pins can also be led by the voltage pull-down of battery core on charging interface It causes the voltage in the power pins to be less than the first voltage threshold value, the condition of offer is provided.

Another optimized work flow of the charging method of the embodiment of the present invention shown in Fig. 3 is only shown for ease of description Go out and the relevant part of the embodiment of the present invention.

As one optional embodiment of the embodiment of the present invention, referring to Fig. 3, whether the determination charging circuit will be described Switch module is connect with the battery core short circuit, including A13 and A14.

A13 determines the voltage of the battery core;

A14 determines that the charging circuit is opened described when the voltage of the battery core is greater than or equal to second voltage threshold value Module is closed to connect with the battery core short circuit.

In the present embodiment, voltage detecting circuit is equipped in electronic equipment, voltage detecting during charging to battery core Circuit detects the voltage of battery core, and the Voltage Feedback control module that will be detected in real time.Preferably, which is set In in control module, the voltage of battery core is detected in real time by the voltage detecting circuit in control module.

Under normal circumstances, the charging voltage that battery core can bear is certain, if power supply unit is exported to electronic equipment The voltage of electric signal be greater than the charging voltage that battery core can bear, such as charging circuit short circuit, the electricity of power supply unit output Pressure can be directly imposed in battery core, and no matter battery core whether full of all being charged by force to battery core, damages battery core.

Therefore, the upper limit for the charging voltage that present embodiment can bear according to battery core in the different charging stages determines institute Second voltage threshold value is stated, the second voltage threshold value determined is more than the charging voltage that battery core can bear.

For example, in constant voltage charging phase, determining second voltage threshold value is more than electricity of the battery core under the state that has been filled with Pressure.

In addition, in battery core under the state that has been filled with, second voltage threshold value is also determined, determining second voltage threshold value is more than Voltage of the battery core under the state that has been filled with.In this way, when battery core has been filled with, if charging circuit is short-circuit, but do not disconnected yet to electricity The charge circuit of core charging;Charging circuit of the power supply unit by short circuit, which forces the voltage in battery core, to be filled more than battery core Voltage under full state, second voltage threshold value can be reached by forcing the voltage in battery core, meet the condition of offer.

For example, in constant-current charging phase, to reduce transmission loss, power supply unit to electronic equipment output with 5V or The charging circuit of the electric signal of the above voltage, electronic equipment is depressured the electric signal and improves electric current, multiple chargings in parallel electricity Road charges simultaneously to battery core, while being 3A or more electric current to the charging current of battery core charging.

Another optimized work flow of the charging method of the embodiment of the present invention shown in Fig. 4 is only shown for ease of description Go out and the relevant part of the embodiment of the present invention.

As one optional embodiment of the embodiment of the present invention, referring to Fig. 4, the charging method further includes A3, A4 and A5.

A3 sends the charging instruction for specifying charging voltage to the power supply unit.

Power supply unit described in present embodiment can be charging adapter, can also be other electronic equipments.But it needs It is bright, it is the charging interface output charging electricity from power supply unit to electronic equipment when electronic equipment is connect with power supply unit Signal charges to the battery core of electronic equipment with the electric signal.

In addition, power supply unit has controller, after power supply unit is connect with electronic equipment, which can set with electronics Standby control module communication.The control module of electronic equipment can send charging adjustment signal (example to the controller of charging adapter Such as the charging instruction), the controller of power supply unit is according to the charging adjustment signal adjustment received:The electricity of power supply unit output Pressure and/or electric current and/or power.

As an optional embodiment, the control module of electronic equipment sends the charging to the controller of charging adapter and refers to It enables, the electric signal for the voltage that charging adapter has the charging instruction specified to electronic equipment output;Preferably, the charging The specified voltage of instruction is greater than or equal to 5V, such as 5V, 9V or 12V.

For example, when charging adapter receives the charging instruction of electronic equipment transmission, if the charging instruction specifies 9V, The controller of charging adapter judges whether to support the voltage output of 9V, if it is decided that support, under the control of the controller The electric signal of 9V is exported to the charging interface of electronic equipment.Under default situations or voltage that the charging instruction is specified be not 5V, When 9V or 12V, charging adapter exports the electric signal of 5V to the charging interface of electronic equipment.

A4 receives the power supply unit and is responded according to the charging that the charging instruction is sent.

In the present embodiment, the power supply unit receives the charging instruction, and judge support fast charge when, set to electronics Standby control module feeds back the corresponding charging response of the charging instruction.As one case study on implementation of present embodiment, the power supply Equipment receives the charging instruction, and when being judged to not supporting fast charge, is not feedback person to electricity to the control module of electronic equipment Sub- equipment feedback is not supported to instruct.

A5 is responded according to the charging, the charge circuit that K charging circuit of conducting charges to the battery core, wherein described K is less than or equal to the N.

In turn, the control module receives charging corresponding with the charging instruction sound of the power supply unit feedback It answers, generates the dispersion charging instruction for specifying K charging circuit.Control module selects K charging electricity according to the dispersion charging instruction The charge circuit that the K charging circuit charges to the battery core is connected in road, by the K charging circuit in parallel to the electricity Core charges.

As one optional embodiment of the embodiment of the present invention, a kind of specific optimization is done to A5, the determination is to the battery core The quantity K of the charging circuit to charge, including:

Determine the charging stage that the electronic equipment is presently in;

According to the charging stage being presently in, the quantity K of the charging circuit to charge to the battery core is determined.

As above-mentioned, the charging stage includes charging stage, constant-current charging phase and constant voltage charging phase.Because of different charging ranks Section, the charging current that battery core can bear is different, and present embodiment adjusts the data K of charging circuit in the different charging stages.

For example, in charging stage, a charging circuit is enough to provide charging of the battery core needed for charging stage Electric current, control module determine that M is numerical value " 1 ";A charging circuit is only connected in control module, is formed pair by this charging circuit The charge circuit of battery core charging;

In constant-current charging phase, two charging circuits are enough to provide the battery core in the charging needed for constant-current charging phase Electric current, control module determine that M is numerical value " 2 ", i.e. two charging circuits are connected in control module, distinguish shape by two charging circuits The charge circuit of pairs of battery core charging, the parallel ground of two charging circuits simultaneously charge to battery core;

In constant voltage charging phase, a charging circuit is enough to provide charging electricity of the battery core needed for constant voltage charging phase Stream, control module determine that M is numerical value " 1 ", i.e. a charging circuit is only connected in control module, are formed pair by this charging circuit The charge circuit of battery core charging.

As a kind of specific implementation mode to the method described in Fig. 2, the method further includes:

Determine the quantity G of the charging circuit to charge to the battery core;

The charge circuit that G charging circuit of conducting charges to battery core, wherein the G is less than or equal to the N.

Specifically, after A3 sends the charging instruction for specifying charging voltage to the power supply unit, if the power supply unit It does not support to export the specified charging voltage of the charging instruction, then the power supply unit will not feed back electronic equipment charging response;Phase Ying Di, the control module in electronic equipment does not receive charging response within a preset period of time, and determines data G.Then, it controls Molding block selects G charging circuit from N number of charging circuit, and the G charging circuit selected is connected and charges simultaneously to the battery core.

As a concrete case of present embodiment, the G is different from the K;In this way, control module do not receive with When the corresponding charging of the charging instruction responds, do not support simultaneously to charge to battery core with K charging circuit.

For example, the charging voltage that the charging instruction is specified is high pressure, if power supply unit is supported to export the high pressure, electronics Equipment needs the number of charging circuit in parallel to be at least K, and the K is more than the G.Need K charging circuit in parallel simultaneously It charges to battery core, charging current is shared by K charging circuit;The number of charging circuit will be unable to undertake charging current less than K, It is easily damaged charging circuit.

For another example the charging voltage that the charging instruction is specified is low pressure, if power supply unit is supported to export the low pressure, electricity It is at most K that sub- equipment, which needs the number of charging circuit in parallel, and the K is less than or equal to the G.Need K charging in parallel Circuit simultaneously charges to battery core, shares charging current by K charging circuit;The number of charging circuit reaches a can undertake of K and fills Electric current, so needing more charging circuits, the work of more charging circuits can bring power attenuation.

As a concrete case of present embodiment, the G is equal to the K;I.e. no matter whether the power supply unit is supported The specified charging voltage of the charging instruction is exported, control module controls K charging circuit conducting, while by parallel K Charging circuit charges to battery core.

As one optional embodiment of the embodiment of the present invention, charging circuit that the determination charges to the battery core Quantity M, including:

For example, filtering out the one or more electricity that need to be worked under the lower working environment of temperature in the electronic device Sub- device;Add temperature detecting module near the electronic device filtered out, screening is detected by the temperature detecting module in real time The temperature (i.e. environment temperature) of the electronic device local environment gone out.Specific implementation of the present embodiment to the temperature detecting module Mode does not limit, such as the physical circuit for being included to temperature detecting module does not limit;For example, temperature detecting module can adopt It is realized with temperature sensor;For another example thermistor realization can be used in temperature detecting module.For some the electronics device filtered out Part, if detecting that higher than temperature threshold corresponding with the electronic device (institute occurs for the environment temperature residing for the electronic device State parameter), trigger the dispersion charging instruction.

Preferably, the parameter includes:The environment temperature of one or more electronic device local environments is high in charging circuit In temperature threshold;Wherein, it is determined for the different operating temperature range of different electronic devices, by the highest of the operating temperature range Temperature is determined as the temperature threshold.

For example, temperature detecting module detects the environment temperature of each charging circuit local environment in real time, and will detection To temperature export to control module.For some charging circuit, if that control module judgement temperature detecting module detects, The environment temperature of the charging circuit local environment is more than corresponding temperature threshold, the dispersion charging instruction is triggered, by the dispersion Charging instruction;And charging circuit, of the specified charging circuit of the dispersion charging instruction are specified by the dispersion charging instruction Number is M.Wherein, the specified charging circuit of the dispersion charging instruction does not include:Local environment temperature should higher than temperature threshold A charging circuit.

The parameter further includes:The ad hoc thing for leading to electronic equipment Accelerating running and electronic equipment being caused to distribute amount of heat Part, for example, application program operating status;The ad hoc event includes at least:1, manipulate electronic equipment high speed executing application And electronic equipment is caused to distribute amount of heat, this event of executing application is the ad hoc event;Such as manipulation electronics is set It is standby to play game, execute this event of games;2, manipulating progress data acquisition of the circuit in electronic equipment etc. needs circuit to hold Continue work and electronic equipment is caused to distribute amount of heat, this event of circuit continue working is described ad hoc in control electronics Event.

During charging to the battery core with the charging circuit less than M, point triggered by the parameter is received After dissipating charging instruction, charged to the battery core with M charging circuit in parallel.Relative to the charging circuit pair less than M The battery core charging, has the following advantages battery core charging with M charging circuit:Because M charging circuit be in parallel to Battery core input current, so share the electric current relative reduction of each charging circuit, to each charging circuit in charging because The heat that electric energy loss is distributed is also opposite to be reduced, to the relative reduction environment temperature of the resistance local environment.
