Detailed description of the invention
The present invention provides the battery activated method and apparatus of a kind of mobile terminal, and for making the purpose of the present invention, technical scheme and advantage clearer, clear and definite, the present invention is described in more detail for the embodiment that develops simultaneously referring to the drawings.Should be appreciated that specific embodiment described herein, only in order to explain the present invention, is not intended to limit the present invention.
Refer to the flow chart of the battery activated method preferred embodiment of the mobile terminal that Fig. 1, Fig. 1 provide for the present invention, described battery activated method, comprise the following steps:
Step S100, after mobile terminal is connected with charger, it is judged that whether the cell voltage of described mobile terminal less than threshold voltage；
Step S200, when described cell voltage less than threshold voltage time, load the first voltage and the first electric current at the two ends of battery to activate described battery；
Step S300, again detect the cell voltage of described battery, it is judged that whether described cell voltage is less than described threshold voltage；If it has, then perform step S400；If it has not, then perform step S500；
Step S400, again load described first electric current at the two ends of battery and increase the first voltage of scheduled voltage successively, returning step S300；
Step S500, restart described mobile terminal.
Below in conjunction with specific embodiment, above-mentioned steps is described in detail.
In the step s 100, after mobile terminal is connected with charger, it is judged that whether the cell voltage of described mobile terminal is less than threshold voltage.Specifically, the present invention is the problem solving cannot activate after existing battery of mobile terminal enters overcurrent protection state, and wherein said mobile terminal is mainly the non-removable mobile terminal of existing battery, it is also possible to be the mobile terminal of battery-disassembled.The present invention is by charger when charging to mobile terminal, and then carrys out activated batteries.Whether there is voltage to input on charging inlet by detection mobile terminal, just can detect whether mobile terminal has charger to insert.When reality is applied, being typically filled with electrical equipment is all 5V output, only need to detect whether charger interface is 5V it is known that whether charger is connected with mobile terminal.Then detecting the cell voltage of mobile terminal, and judge whether less than threshold voltage, if being less than, then illustrating that the battery of mobile terminal enters overcurrent protection state；If cell voltage is not less than threshold voltage, then illustrates that the battery of mobile terminal does not enters into overcurrent protection state, charge normal.Wherein, described threshold voltage can be configured according to the actual requirements.
The most in step s 200, when described cell voltage is less than threshold voltage, the first voltage and the first electric current are loaded at the two ends of battery to activate described battery.Specifically, when described cell voltage is less than threshold voltage, the most just illustrates that the battery of described mobile terminal enters overcurrent protection state, then load the first voltage and the first electric current at the two ends of battery, be used for activating described battery.The battery of existing activation overcurrent protection, has two kinds of methods: the first is above-mentioned being pulled down by battery, makes the load impedance being connected on battery sufficiently high；The second is at battery two ends plus a voltage higher than battery virtual voltage, and just can activate the battery of overcurrent protection plus a small area analysis (such as 200mA)；Such as; current battery level is 3.9V, and now mobile phone causes battery overcurrent protection due to instantaneous short circuit, then if not realizing activating this battery by dismounting battery, needs battery two ends plus the voltage higher than 3.9V again; and input a small area analysis, just can activate this battery.Therefore, described battery can just be activated by loading the first voltage and the first electric current.
In step S300, again detect the cell voltage of described battery, it is judged that whether described cell voltage is less than described threshold voltage；If it has, then perform step S400；If it has not, then perform step S500.Specifically, it is being carried in after battery two ends activate this battery with the first voltage and the first electric current of short duration (the most several milliseconds), in order to detect whether battery is successfully activated, again detect the cell voltage of described battery, and judge that whether described cell voltage is less than described threshold voltage；If it has not, then show that battery has been successfully activated, then perform step S500, restart described mobile terminal；If it has, then show that TV does not the most activate successfully, then perform step S400 and continue to activate described battery.
In step S400, described battery is not activated owing to loading the first voltage and the first electric current, then illustrate that the voltage loaded is the least, when continuing activated batteries, the magnitude of voltage activating voltage is increased by a scheduled voltage on the basis of original, and use the first original electric current to continue to activate described battery, i.e. return step S300 and continue to activate, until cell voltage is not less than described threshold voltage.So, increased by a little and activate magnitude of voltage of voltage and carry out progressively activated batteries, it is to avoid once load bigger voltage at battery two ends and carry out the injury that battery is caused by activated batteries.
When reality is applied, whether the charger interface of described mobile terminal detection mobile terminal has voltage to input, and when detecting that described charger interface has voltage to input, then mobile terminal is connected with charger；Then detect the cell voltage of described mobile terminal, and judge that whether described cell voltage is less than threshold voltage.When described cell voltage is not less than threshold voltage, the battery of the most described portable power source is not on overcurrent protection state；When described cell voltage is less than threshold voltage, it is the first voltage that power management chip arranges activation voltage, and arranging activated current is the first electric current.Then described first voltage and the first electric current are loaded at the two ends of battery to activate described battery.It is 0 that power management chip arranges activated current, again detects the cell voltage of described battery, it is judged that whether described cell voltage is less than described threshold voltage；If it has, then perform step S400；If it has not, then perform step S500.Activated current is set to 0 by power management chip, and the battery voltage value that so detection obtains is more accurate.When reality is applied, the magnitude of voltage of described first voltage is equal to the magnitude of voltage of described threshold voltage.
Refer to the method flow diagram in the battery activated method Application Example of the mobile terminal that Fig. 2, Fig. 2 provide for the present invention, as it can be seen, the battery activated method that described mobile terminal uses, comprise the following steps:
S1, when detecting that mobile terminal connects charger, if detecting, cell voltage Vbat less than V1, arranges activation magnitude of voltage V=V1, performs S2 afterwards；
S2, activated current value I=I1 is set, performs S3 afterwards；
S3, activated current value I=0 is set, performs S4 afterwards；
S4, detection cell voltage Vbat, perform S5 afterwards；
S5, judge that Vbat, whether less than V1, if it is performs S6, otherwise performs S11；
Activation magnitude of voltage is increased Δ V by S6, V=V+ Δ V(on the original basis), perform S7 afterwards；
S7, arrange activation voltage V, perform S8 afterwards；
S8, activated current value I=I1 is set, performs S9 afterwards；
S9, activated current value I=0 is set, performs S10 afterwards；
S10, detection cell voltage Vbat, perform S5 afterwards；
Program of mobile terminal is restarted in S11, execution.
Wherein, it is preferred that V1 could be arranged to 3.0V, I1 could be arranged to 100mA, Δ V and could be arranged to 50mV.
