As stated in the Background Art, when battery core being charged by charging circuit, may be short-circuit because of this charging circuit, The voltage making the signal of telecommunication that power supply unit exports is directly over the charging circuit of short circuit and is imposed in battery core, damages Bad battery core, even results in battery core and bursts.Therefore, the embodiment of the present invention is at the electricity of charging circuit Yu charging inlet Connect between the pin of source a switch module, if certain charging circuit short circuit, can directly control this switch Module disconnects the charge circuit that battery core is charged by all charging circuits, stops charging battery core.

It should be noted that, the charging inlet of electronic equipment includes data pin;Electronic equipment passes through its charging After mouth is connected with power supply unit, electronic equipment can be carried out data transmission with power supply unit by this data pin, The data can transmitted by this data pin are not limited to the data relevant to charging, it is also possible to transmission audio frequency and video literary composition Part, document files etc. data.

Specifically, the workflow of this charging method of the embodiment of the present invention shown in Fig. 1, but for the ease of retouching State, illustrate only the part relevant to the embodiment of the present invention.This charging method of the embodiment of the present invention includes A1 And A2.

It should be noted that, in the charging process of described electronic equipment, charged electrical signal sequentially pass through described in fill Electrical interface, described switch module, M described charging circuit and described battery core, described M is less than or equal to N, Described M is positive integer.Specifically, power supply unit exports charged electrical signal, this charging telecommunications to electronic equipment Number sequentially pass through described charging inlet, described switch module, M described charging circuit in parallel and described electricity Core, charges to described battery core with this charged electrical signal.

A1, in the charging process of described electronic equipment, determines that whether described charging circuit is by described switching molding Block is connected with described battery core short circuit.

Specifically, after power supply unit electrically connects with the charging inlet of electronic equipment, turn on institute at switch module Stating under the power pins of charging inlet and the state of one or more charging circuits, power supply unit sequentially passes through electricity Battery core is charged by the charging circuit of the charging inlet of subset, switch module and M parallel connection.

Wherein, because of described M be positive integer, i.e. A1 can with at least one charging circuit to battery core charge.Work as M During more than 1, battery core is charged by the charging circuit of M in parallel, M charging circuit in parallel share electricity The electric current of core charging;So, it is possible to decrease the caloric value that each charging circuit brings because of electric energy loss.

It addition, in the different charging stages charging battery core, control module can adjust the numerical value of M, i.e. adjust Battery core is charged by how many charging circuits of whole use simultaneously, is illustrated below:

In the preliminary filling stage, control module determines that M is that numerical value " 1 ", i.e. control module only turn on a charged electrical Road, 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. two chargings of control module conducting Circuit, forms the charge circuit to battery core charging, two charging circuit parallel connections respectively by two charging circuits Battery core is charged by formula ground simultaneously;

At constant voltage charging phase, control module determines that M is that numerical value " 1 ", i.e. control module only turn on one and fills Electricity 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, during charging battery core, is filled described in how determining With described battery core short circuit is connected, whether described switch module is specifically determined that mode does not limits by electricity circuit.

As determining that whether described charging circuit one determines described switch module is connected with described battery core short circuit Mode, detects whether described charging circuit is connected described switch module with described battery core short circuit in real time, but right How to detect the specific implementation that switch module is connected with described battery core short circuit not limit;

Illustrating, the electric current of charging circuit is flow through in detection, if be detected that electric current more than current threshold, Represent that switch module is connected by charging circuit with battery core short circuit;Illustrate again, at constant voltage charging phase, The voltage of the signal of telecommunication that detection charging circuit export to battery core, if be detected that voltage be more than battery core saturated Voltage (i.e. battery core voltage under having been filled with state) under state, represents that charging circuit is by switch module It is connected with battery core short circuit.

A2, when described switch module is connected by described charging circuit with described battery core short circuit, opens described in control Close module and disconnect the electrical connection of described charging inlet and described charging circuit, to stop by described charging circuit Battery core is charged;

Specifically, the switch module that the embodiment of the present invention provides is by control module control, specifically, by controlling Module controls being switched on or off of switch module;When control module controls switch module conducting, conducting is filled The power pins of electrical interface and the electrical connection of charging circuit;When control module controls switch module disconnection, disconnected Open the power pins of charging inlet and the electrical connection of charging circuit.

In embodiments of the present invention, control module once detects that described charging circuit is by described switch module It is connected with described battery core short circuit, controls switch module immediately and disconnect described charging inlet and described charging circuit Electrical connection so that the charge circuit charged battery core by arbitrary charging circuit is all disconnected, stops battery core Charging, protects battery core.

A kind of optimized work flow of this charging method of the embodiment of the present invention shown in Fig. 2, for the ease of describing, Illustrate only the part relevant to the embodiment of the present invention.

As the optional embodiment of the embodiment of the present invention one, see Fig. 2, described determine described first charged electrical Whether road is connected described switch module, including A11 and A12 with described battery core short circuit.

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 described charging Described switch module is connected by circuit with described battery core short circuit.

Present embodiment specifically determines mode to the voltage in the power pins how determining described charging inlet Do not limit.As an implementation, in electronic equipment, it is provided with voltage detecting circuit, this voltage detecting circuit Electrically connecting with the power pins of charging inlet, during charging battery core, voltage detecting circuit detects in real time and fills The voltage of the power pins of electrical interface, and the Voltage Feedback control module that will detect.Preferably, by this electricity Pressure testing circuit is located in control module, the voltage detecting circuit in control module detect charging inlet in real time The voltage of power pins.

Under normal circumstances, the charging voltage that battery core can bear is certain, and power supply unit sets to electronics The voltage of the signal of telecommunication of standby output is greater than the charging voltage that battery core can bear, if charging circuit is short-circuit, The voltage of power supply unit output can directly be imposed in battery core, and the voltage of power supply unit output can directly be imposed to In battery core, whether battery core is full of all is charged by force to battery core, damages battery core.

If it addition, charging circuit is short-circuit, because battery core is directly over the charging circuit of short circuit, the switch of conducting Module electrically connects with the power pins of charging inlet, and the voltage of battery core can be directly by the power pins of charging inlet Voltage pull-down, cause the power pins of charging inlet to be greatly reduced.Therefore, present embodiment is according to difference The voltage that under charging stage, battery core has been rushed determines described first voltage threshold, described first voltage threshold determined The voltage rushed higher than battery core, the experimental data such as the impedance of internal circuit according to switch module during concrete application Determine this first voltage threshold.

Illustrating, at constant voltage charging phase, the first voltage threshold determined is having been filled with state more than battery core Under voltage.

It addition, battery core is under having been filled with state, also determine the first voltage threshold, the first voltage threshold determined Value is more than battery core voltage under having been filled with state.So, when battery core has been filled with, if charged electrical is short out Road, fails to disconnect the charge circuit to battery core charging;Power supply unit is forced at electricity through the charging circuit of short circuit Voltage on core can be more than battery core voltage under having been filled with state, charges battery core by force, charging simultaneously The voltage of mouth power source pin also can be caused the voltage in this power pins less than institute by the voltage pull-down of battery core State the 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 the ease of retouching State, illustrate only the part relevant to the embodiment of the present invention.

As the optional embodiment of the embodiment of the present invention one, see Fig. 3, described determine that described charging circuit is No described switch module is connected, including A13 and A14 with described battery core short circuit.

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 charging circuit will Described switch module is connected with described battery core short circuit.

In the present embodiment, in electronic equipment, it is provided with voltage detecting circuit, electricity during battery core is charged Pressure testing circuit detects the voltage of battery core, and the Voltage Feedback control module that will detect in real time.Preferably, This voltage detecting circuit is located in control module, the voltage detecting circuit in control module detects electricity in real time The voltage of core.

Under normal circumstances, the charging voltage that battery core can bear is certain, if power supply unit sets to electronics It is short-circuit that the voltage of the signal of telecommunication of standby output is greater than the charging voltage that battery core can bear, such as charging circuit, The voltage of power supply unit output can directly be imposed in battery core, and whether battery core is full of all is carried out by force battery core Row charging, damages battery core.

Therefore, the upper limit of the charging voltage that present embodiment can bear in the different charging stages according to battery core is true Determine described second voltage threshold, the charging voltage that this second voltage threshold determined can bear more than battery core.

Illustrating, at constant voltage charging phase, the second voltage threshold determined is having been filled with state more than battery core Under voltage.

It addition, in battery core under having been filled with state, also determine the second voltage threshold, the second voltage determined Threshold value is more than battery core voltage under having been filled with state.So, when battery core has been filled with, if charging circuit Short circuit, but do not disconnect the charge circuit to battery core charging yet;Power supply unit is forced through the charging circuit of short circuit Voltage in battery core can be more than battery core voltage under having been filled with state, and forcing the voltage in battery core can reach To the second voltage threshold, meet the condition provided.
