Second preset condition includes: that the remaining capacity of battery is more than or equal to the second power threshold;The electricity reduction rate of battery is less than or equal to the second electricity reduction rate threshold value;The discharge current of battery is less than or equal to the second discharging current threshold;According to the electricity reduction rate and remaining capacity of battery calculate battery can power-on time be more than or equal to second time threshold.
It should be noted that step S1022 might not be dependent on the target charge current in step S1021, it can adjusted on the basis of target charge current further according to stair step current value, or do not execute step S1021 and directly adjusted according to stair step current value.Such as assume that current charging current thresholding is 1A, stair step current value is 0.05A, then charging current thresholding is adjusted to 1.05A, next cycle is similarly adjusted.In addition, the application does not limit stair step current value as fixed value, it equally can be variable value, the value in latter period can be greater than with the value of previous cycle, such as previous cycle stair step current value is 0.1A, next period stair step current value becomes 0.08A, then next period stair step current value becomes 0.05A etc..
Above-mentioned steps S1021 and S1022 are equivalent to the closed-loop control in Theory of Automatic Control, optionally, The application provides another implementation for the charging current thresholding of raising battery described in step S102, opened loop control can be used, it can specifically be realized by directly setting fixed threshold for charging current thresholding, referring to fig. 6, step S102 may include step S1023:
S1023, directly by charging current thresholding charging current threshold value is set.
Furthermore it is possible to which charging current threshold value is set different values by the loss situation according to electricity, it can there is multistage charging current thresholding.For example, when the electricity of battery is lower charging current thresholding is arranged higher, so that quickly charge when quantity of electric charge decrement is more, trickle charge when quantity of electric charge decrement is less.
Optionally, when changing battery charging state, the embodiment of the present application can also on the graphical user interface of terminal device display reminding information, referring to fig. 7, the above method further includes step S105 and S106:
S105, battery meet the first preset condition at least one of when, the display reminding information on the display interface of terminal device, to prompt user currently to improve the charging current thresholding of battery, and the power consumption or control cooling unit execution cooling action of heating device are reduced.
Illustratively, referring to fig. 8, " being adjusted into charging and reducing power consumption mode ", " into improving charging current and reducing power consumption mode " etc. can be shown, specific prompt information includes but is not limited to the forms such as text, icon, figure, pattern.It will be understood by those skilled in the art that the manifestation mode of description prompt information merely exemplary in figure, is not intended to limit the particular content of prompt information.
S106, when the second preset condition described in battery meets step S1022 at least one of when, restore to former temperature control strategy, stopping shows above-mentioned prompt information on the display interface of the mobile terminal.
For example, charging current thresholding is reverted into the value before adjustment, the value etc. before adding tight variable to revert to plus is tight other in temperature control strategy.
It illustrates below and above embodiment is described in detail.
For example, it is assumed that the first power threshold of certain terminal device is set as 10%, the first discharging current threshold is set as 0mA.Each period is monitored external power supply and battery capacity, in the case where external power detector has detected that external power supply provides external power supply, and when voltameter detects that battery capacity decreases below 10%, voltameter starts to be monitored the discharge current of battery.When voltameter detects that discharge current is greater than 0mA, judged to meet the first preset condition by processor, display reminding information on display interface is controlled, and the low battery correction module of processor controls external power supply detection device in the period with the charging current thresholding of preset stair step current value raising temperature control strategy.Such as the charging current thresholding of current temperature control strategy is 1A, stair step current value is 50mA, then improves charging current thresholding to 1.05A.At least one of next cycle executes same operation, until in battery the second preset condition of satisfaction, and restore original temperature control strategy automatically.
At this time, since the loss that charging current increase causes becomes larger and then causes to generate heat, other control variables other than charging current thresholding add sternly by the temperature control module of processor to eliminate, such as reduce the highest frequency threshold value of processor, reduces the display brightness etc. of display module.Such as, when by be originally 1A charging current thresholding limit be adjusted to 1.1A when, increased 0.1A charging current increases equipment surface temperature by 0.5 degree, then the highest frequency threshold value of central processing unit can be down to 1.3GHz from 1.5GHz, or the display brightness of display module is down to 125nit etc. from 150nit (nit), the additional temperature rise of bring is raised by charging current thresholding with compensation.
Charging current threshold regulating method and device provided by the embodiments of the present application; mainly pass through monitoring battery capacity, electric quantity change situation and battery discharge current situation; to improve the charging current thresholding of battery; it is unable to make ends meet because temperature control causes to charge with reduction; perhaps equipment power dissipation is excessive causes to trigger temperature safety protection or the excessive ceiling capacity etc. that can be provided beyond external power supply of power consumption.While the charging current thresholding in view of improving temperature control strategy, it is possible that battery-heating amount is caused to increase, therefore accordingly plus remaining control variable of tight temperature control strategy guarantees that whole calorific value does not increase, not only battery capacity caused by having eliminated because of temperature control strategy is persistently reduced, but also can ensure hot experience to a certain degree.
Charging current thresholding described in the embodiment of the present application includes but is not limited to the charging current thresholding in common temperature control strategy, it is equally applicable for the charging current thresholding in the charging strategies such as quick charge, as long as at least one of the electricity of battery, discharge current and voltage meet preset condition, so that it may adjust charging current thresholding according to method provided by the embodiments of the present application.In addition, when also can be applied to the power supply of no external cell, the embodiment of the present application is not construed as limiting when charging current threshold regulating method described in the embodiment of the present application can be applied to external cell power supply.
