Fig. 1 is the flow chart of the charging method of one embodiment of the present of invention.As shown in Figure 1, this method includes:
Step 120, when meeting preset condition, charger exports first voltage to mobile terminal so that at mobile terminal In short-circuit detecting state;Preset condition includes charger and the USB interface of mobile terminal is in connection status.
Herein, first voltage can have different values in different situations.For example, first voltage can be Threshold voltage when mobile terminal is charged during standard charging.For the different situations of first voltage, the present embodiment is following It is specifically described in content.
Step 140, the first output current under first voltage is obtained.
Since under the first voltage, battery charging of the charger not into mobile terminal, therefore, charger can be with shifting Foreign matter load forming circuit in the USB interface and USB interface of dynamic terminal.It is appreciated that according to foreign matter load resistance Size, charger can export corresponding first output current.
Step 160, when the first output current is less than the first preset value, target voltage is exported so that mobile terminal is in Charged state.
Herein, when the first output current is less than the first preset value, then illustrate that foreign matter loads the resistance sizes to be formed simultaneously It is not enough to influence battery charging of the charger into mobile terminal, at this point, charger can then export target voltage to mobile end Battery charging in end.On the contrary, when the first output current is more than the first preset value, then illustrate that foreign matter loads the resistance to be formed It is larger, in charging process, more heat can be generated in the USB interface of mobile terminal, the USB of mobile terminal is caused to connect Mouth short circuit is so as to be burned.
In embodiments of the present invention, charger can automatically be adjusted the output voltage of itself, specifically, charging Output voltage can be adjusted to first voltage by device, and under the first voltage, mobile terminal is in short-circuit detecting state;Later, By the first voltage, charger can obtain the first output current of itself output, when first output current is less than first During preset value, charger can then export battery charging of the target voltage into mobile terminal;On the contrary, when the first output electricity When stream is more than the first preset value, due to the battery charging in the not oriented mobile terminal of charger at this time, then illustrate mobile terminal USB in foreign matter cause USB short-circuit, charger can then charge to avoid the battery into mobile terminal lead to USB interface quilt It burns out, charger can actively avoid the USB for burning out mobile terminal from connecing in the battery charging into mobile terminal as a result, Mouthful.
The mobile terminals such as mobile phone can check input voltage after charger is accessed, when input voltage is more than gate valve voltage When, mobile phone can just start to charge up (sourcing current).When input voltage is less than gate valve voltage, mobile phone does not charge.
More than charging principle is based on, in a realization method of the present embodiment, the USB interfaces to judge mobile terminal are No short circuit, charger can directly export first voltage, which is less than gate valve after socket connection alternating current is inserted into Voltage.After charger is connect with mobile terminal, since first voltage is less than gate valve voltage, charger will not be to mobile terminal Interior battery charging.At this point, charger can obtain the first output current of itself output.When in the USB interface of mobile terminal Foreign matter load resistance it is larger when, which can be larger, if it greater than the first preset value, then illustrates foreign matter Load can cause USB interface short-circuit, be burned so as to cause USB interface.On the contrary, only it is less than first in the first output current During preset value, just illustrate that foreign matter load will not cause USB interface to be burned, at this point, charger can export target voltage pair Battery in mobile terminal charges.Herein, target voltage can be above-mentioned gate valve voltage, and certainly, target voltage also may be used To be more than above-mentioned gate valve voltage.
It is further noted that when the resistance of the foreign matter load in the USB interface of mobile terminal is larger, if Charger charges to the battery in mobile terminal, and foreign matter load can cause USB interface short-circuit, burn out USB interface.To keep away Exempt from such case, shown in Fig. 2, this method further includes:
Step 170, when the first output current is more than the first preset value, first voltage is continued to output so that mobile terminal In short-circuit detecting state, until the first output current is less than the first preset value.
When the first output current is more than the first preset value, charger can recycle output first voltage, until first defeated Go out electric current less than the first preset value, later, charger output target voltage charges to mobile terminal.
In the present embodiment, when the first output current is more than the first preset value, after charger can be with separated in time section First voltage is exported again.The length of specific interval time can be configured as needed.
The present embodiment can combine Fig. 3 and Fig. 4 and further illustrate.As shown in figure 3, charger access is inserted before the t0 moment Seat, output first voltage V1.First voltage V1 is less than the gate valve voltage of mobile phone.If t0 moment chargers are connect with mobile phone, by It is less than the gate valve voltage of mobile phone in first voltage V1, therefore, mobile phone does not charge under first voltage V1.In t0 to t1 periods Interior, charger can obtain its first output current I1 under first voltage V1, if I1 is less than the first preset value I, table Show that the load in the USB interfaces foreign or foreign matter of mobile terminal does not influence to charge normal.At this point, at the t2 moment, charging Device can export target voltage V2, and target voltage V2 can be gate valve voltage, can also be more than gate valve voltage, so as to make to fill Electric appliance starts to charge up mobile phone.
If on the contrary, as shown in figure 4, the first output current I1 that charger obtains in t0 to t1 periods is more than the One preset value I, at the t1 moment, charger then enters guard mode, and later, charger can export the first electricity again at the t2 moment V1 is pressed, cycle obtains the first charging current I1 and judged, until the first charging current I1 is less than the first preset value I.Wherein, Guard mode can be charger not output voltage in t1 to t2 periods, and certainly, charger can also be in other protections State, the present embodiment are no longer described in detail one by one.Interval time is t1 to the t2 periods herein.

It should be pointed out that during battery charging of the charger output target voltage into mobile terminal, it is preferred that the mesh Marking voltage can be identical with second voltage.Certainly, the present embodiment allows target voltage different from second voltage.
On the contrary, when the second output current is less than the second preset value, illustrate there is no foreign matter in the USB interface of mobile terminal, Or foreign matter does not interfere with charging.At this point, charger can continue to output second voltage, until the second output current is more than institute State the second preset value.It is understood that when the second output current is continuously less than the second preset value, then charger can be straight Output second voltage is connect to charge to mobile terminal.
It is appreciated that the second voltage can be gate valve voltage, gate valve voltage can also be more than,
Fig. 6 is the flow chart of the charging method of yet another embodiment of the present invention.As shown in fig. 6, this method further includes:
Step 180, when the first output current is more than the first preset value, charger exports second voltage to mobile terminal, Until the second output current is more than the second preset value.
When the first output current is more than the first preset value, then illustrate that there may be different in the USB interface of mobile terminal Object may cause USB interface to be burned when charger charges to mobile terminal.For this purpose, when the first output current is more than first in advance If during value, charger can recycle output second voltage, obtain the second output current under second voltage, until second defeated Go out electric current more than the second preset value.At this point, since the second output current more than the second preset value meets preset condition, charger First voltage can be then exported, subsequent execution step and process are referred to described in the above content of the present embodiment, this implementation Example no longer specifically repeats herein.Whether this cycle can rejudge charger can be directly under second voltage to moving Dynamic terminal charges, and USB interface can also be avoided to be burned.
The present embodiment can combine Fig. 7 and Fig. 8 and further illustrate.As shown in fig. 7, before the instant t 0, charger connection Socket exports second voltage V3, and second voltage V3 is greater than or equal to gate valve voltage.It is appreciated that it before the instant t 0, fills Electric appliance zero load output is normal.Assuming that it is connect in t0 moment chargers with mobile phone, since second voltage V3 is greater than or equal to gate valve electricity Pressure, therefore, mobile phone starts to charge up.Assuming that at the t1 moment, mobile phone starts to charge up, at this point, charger obtains the second output current I2.When the second output current I2 is less than the second preset value, charger can directly charge to mobile phone with the second voltage.This Embodiment is further specifically described when I2 is more than the situation of the second preset value.
When I2 is more than the second preset value, charger can export first voltage V1.Assuming that charger exports at the t2 moment One voltage V1, at this point, charger can obtain the first output current I3 under first voltage V1, when the first output current I3 is small When the first preset value I, illustrate there is no foreign matter or foreign matter not to be impacted to charging in mobile terminal, at this point, charging Device can export target voltage and charge to the battery in mobile terminal.Here, target voltage can be with second voltage V3 phases Together.Assuming that charger is t3 at the time of exporting target voltage, then since the t3 moment, charger charges normal mobile phone.
As shown in figure 8, when the first output current I3 is more than the first preset value I, charger then enters guard mode, and Export second voltage V3.Assuming that detecting that the first output current I3 is more than the first preset value I in t3 moment chargers, then charge Device enters guard mode at the t3 moment.Guard mode can be charger not output voltage in t3 to t4 periods, certainly, Charger can also be in other guard modes, and the present embodiment is no longer described in detail one by one.
More than charging process can not only ensure that the USB interface of mobile terminal is not burned, can also be in mobile terminal When USB interface does not have foreign matter, make charger and directly charged with second voltage to the battery in mobile terminal.
Fig. 9 is the flow chart of the charging method of yet another embodiment of the present invention.As shown in figure 9, before step 120, it should Method further includes:
Step 113, charger exports tertiary voltage to mobile terminal, and mobile terminal detection is made to be under tertiary voltage No success of shaking hands with charger;
Step 114, charger determines whether to get what mobile terminal was sent when detecting and shaking hands successfully with charger Solicited message, solicited message are used to that charger to be made to export first voltage;
Preset condition further includes:Charger gets solicited message.
In another realization method of the present embodiment, charger can directly export tertiary voltage after socket is accessed.Its In, tertiary voltage is more than the gate valve voltage of mobile terminal.At this point, charger can charge to mobile terminal.
Charger with tertiary voltage to mobile terminal charge when, and can if the USB interface of mobile terminal has foreign matter To cause USB short-circuit, at this point, charger can directly acquire the third output current that it is exported under tertiary voltage, and sentencing When breaking it more than preset threshold value, directly forbid charging to mobile terminal.The threshold value can be opposite one larger electricity of setting Flow valuve.
Certainly, more situations that the present embodiment is further illustrated, although being then USB interface foreign or having different Object, but these foreign matters are not sufficient to that USB interface is caused quickly to be burnt out or in the case where there is foreign matter, and USB interface is burnt The bad time is significantly larger than the time of the present embodiment above procedure realization, and when the present embodiment then will avoid charging normal causes The situation that USB interface is burned.
Specifically, after charger exports tertiary voltage, mobile terminal, which can first detect whether to establish with charger, to be connected It connects.If establishing connection, charger if, starts to charge to mobile terminal, at this point, charger can obtain the under tertiary voltage Three output currents.After charging, mobile terminal can with charger carry out communication handshake, mobile terminal detects shake hands successfully after, meeting A solicited message is sent out, the purpose of the solicited message is that charger is made to export first voltage.Under the first voltage, charging Device will not charge to mobile terminal.According to the solicited message, since the solicited message meets preset condition, at this point, charger can To export first voltage according to solicited message, and perform corresponding other steps.Other steps after specific step 120 It is illustrated in the above content of the present embodiment, here, the present embodiment no longer specifically repeats.
Wherein, it is to realize two current embodiment require that, it is noted that shake hands between charger and mobile terminal Fast charge mode between person.In the present embodiment, step 160 can be implemented as:
Charger exports target voltage to mobile terminal, and exports the target charge current more than standard charging current;
It is charged according to target charge current to the battery in mobile terminal.
At this point, target voltage is greater than tertiary voltage.Target charge current is greater than standard charging current or normally fills Electric current, so as to which charger be made to charge with fast charge mode to mobile terminal.
In the present embodiment, charger output tertiary voltage, and after getting solicited message, due to solicited message meet it is pre- If condition, therefore, charger output first voltage, and the first output current under first voltage is obtained, when the first output electricity When stream is more than the first preset value, charger can repeat output tertiary voltage, until getting solicited message.This cyclic process It may determine whether to charge to mobile terminal with fast charge mode, and when the USB interface of mobile terminal has foreign matter, to moving The USB interface of dynamic terminal is protected.
The present embodiment can not only be burned to avoid USB as a result, can also make charger in a manner of fast charge to movement Terminal charges, and improves charge efficiency.
The present embodiment can combine Figure 10 and Figure 11 and further illustrate.As shown in Figure 10, charger is after socket is accessed, Tertiary voltage V4 can directly be exported.Tertiary voltage V4 can be the acquiescence output voltage of charger.Assuming that at the t0 moment, fill Electric appliance is connect with mobile phone, and within t0 to the t1 periods, mobile phone can detect whether to connect with charger, within t0 to the t1 periods Mobile phone does not charge.When mobile phone, which is detected, to be connect with charger, then charger is allowed to charge to it.Assuming that at the t1 moment, charging Device starts to charge to mobile phone, at this point, charger can obtain itself third output current I4 in tertiary voltage V4.If Third output current I4 is more than a certain specific threshold value, and charger then can directly be forbidden charging to mobile terminal.The threshold Value can be a larger numerical value.Under normal conditions, third output current I4 is less than the threshold value, represents in mobile terminal USB interface in foreign either foreign matter does not influence to charge or the foreign matter is not sufficient to that USB interface is caused quickly to be burnt Bad or in the case where there is foreign matter, the time that USB interface is burned is significantly larger than the realization time of the present embodiment, the realization Time can be limited by way of preset time value.
Assuming that the t12 moment after instant tl, charger starts communication handshake, and until the t2 moment, shake hands with mobile phone Success.After mobile terminal detects that it shakes hands successfully with charger, a solicited message can be sent out, which can be with For making charger output first voltage V1.First voltage V1 is less than tertiary voltage V4.Assuming that charger the t2 moment according to please Seek information output first voltage V1.At this point, charger can obtain the first output current I5 under first voltage V1, when first When output current I5 is less than the first preset value I, then it represents that foreign or foreign matter, which have no effect on, in the USB interface of mobile phone fills Electricity.At this point, charger can charge to mobile terminal in a manner of fast charge.Assuming that charger starts at the t3 moment with fast charge Mode charges to mobile phone.At this point, the target voltage of charger output is V5, target voltage V5 is more than tertiary voltage V4, The target charge current of charger output is I6, and target charge current I6 is more than third output current I4.
As shown in figure 11, when the first output current I5 is more than the first preset value I, then illustrate the USB interface of mobile terminal Inside there is foreign matter, which is likely to result in USB interface and is burned.At this point, from the t3 moment, charger enters guard mode, until The t4 moment.At the t4 moment, charger then exports tertiary voltage V4, and detecting whether again can be to mobile terminal with fast charge mode It charges, recycles above procedure.
With reference to above it is found that the present embodiment can not only be burned to avoid the USB interface of mobile terminal, can also move When not influencing charging without foreign matter or foreign matter in the USB of dynamic terminal, charged with fast charge mode to mobile terminal.
