Embodiments herein is described below in detail, the example of the embodiment is shown in the drawings, wherein from beginning to end
Same or similar label represents same or similar element or the element with same or like function.Below with reference to attached
The embodiment of figure description is exemplary, it is intended to for explaining the application, and it is not intended that limitation to the application.
Below with reference to the accompanying drawings the charge control method, device and terminal device of the embodiment of the present application are described.
First, in order to which clearly to the application, each embodiment illustrates, first, to several nouns in the application
It explains.
" cutoff voltage value of charging chip " in the embodiment of the present application refers to according to serving as the rated voltage of chip, can be with
Setting be used for judge battery whether a reference value of charging complete, be less than charging chip safe voltage value, that is, be less than charging
The load voltage value of chip." reference voltage value " is that the application is set, the base for continuing to charge for battery is judged whether to need
Quasi- value, when the voltage of battery is equal to a reference value, it is determined that battery has been completed to charge.
For example, if the rated voltage for serving as chip is 4.35 volts (V), after blanking voltage considers safe clearance,
May be 4.25,4.2V or 4.18V etc..
Fig. 1 is the flow diagram of the charge control method of the application one embodiment.
As shown in Figure 1, the charge control method includes：
Step 101, judge whether the current voltage value of battery is equal to reference voltage value, the reference voltage value is less than or waits
In the cutoff voltage value of charging chip.

Specifically, if battery control device determines that the current voltage value of battery is equal to reference voltage value, electricity can be monitored
Whether the charging current in pond is zero, if zero, then illustrates that the current voltage value of the battery of charging chip monitoring is equal to reference voltage
Value, and controlled the charging process finished to battery.
And if serve as control device and monitor that charging current at this time is not zero, illustrate, charging chip is still to electricity
Pond is charged, i.e., the current voltage value of the battery that charging chip monitors at this time is still below reference voltage value, then illustrates to charge
The voltage sampling circuit of chip has deviation so that the voltage value monitored is less than actual value, at this time can be by adjusting charging core
The reference voltage of piece, it is ensured that charging chip is made to terminate the charging to battery when the current voltage value of battery is equal to a reference value
