If whether discharge current is more than maximum charging current IsysMax, illustrate that battery needs to power to mobile terminal, electric discharge
The size of electric current is relevant with the power consumption of mobile terminal and in change.Assuming that now continue to charge, also will not be to battery powered, electricity
Pond can carry out discharge and recharge switching.Therefore, when judging that discharge current is more than maximum charging current IsysMax, by the second count value k2
Add 1, i.e. k2=k2+1.
Step 303, when the second timing reaches, judge whether the second count value is more than the second preset times：It is then
Perform step 301；Otherwise step S400 is performed.
In this implementation, the second preset times kth2 is 0.Only in 5 seconds, the discharge current of battery is less than or equal to maximum
Charging current IsysMax, i.e. | Ibat |（Assuming that battery charge is equal with discharge current, represented with Ibat）It is less than or waits
In | IsysMax | it can just reopen charging；Now if opening charging ensures that to be not in what battery charging and discharging switched
Phenomenon.Need to continue to stop charging and judging size if being more than.
It before needing to reopen charging, need to judge whether battery is fully charged, full of then prompting electricity full, terminate to fill
Electricity.Then return to step S200 is again started up charging for underfill, continues to judge whether continually carried out discharge and recharge switching in 5 seconds.
Discharge and recharge frequent switching can be reduced through the above way, battery is played a very good protection, and also extended
The service life of battery.
