Illustrated below by specific embodiment.In embodiment one, the present invention provides a kind of mobile terminal, the shifting Dynamic terminal can use the battery-powered each class of electronic devices of lithium-ion electric, such as mobile phone, tablet personal computer, notebook computer, intelligence Energy Wearable etc., in the present embodiment, the mobile terminal is mobile phone.The mobile terminal sets and is improved charging rate System, refer to Fig. 1, and the system includes lithium ion battery 10, charging module 20, processing module 30 and reminding module 40.
The lithium ion battery 10 is used to provide power supply for mobile terminal.
The charging module 20 (such as charging circuit), for being charged to lithium ion battery 10, and obtains lithium ion in real time The charge capacity of battery 10.
Filled specifically, charging module 20 includes charging stage, constant-current charging phase and constant pressure to the charging of lithium ion battery 10 These three stages in electric stage, or only include charging stage and the two stages of constant-current charging phase.As shown in Fig. 2 preliminary filling rank Section:When the voltage of lithium ion battery 10 is no more than pre-charge pressure, charging module 20 carries out current-limiting charge (electricity to lithium ion battery Flow for the horizontal linear section of Fig. 2 charging current curve lowest parts).Charging stage refers to when the voltage ratio of lithium ion battery 10 is relatively low When, usually below 3V, to protect lithium ion battery service life, the stage of current-limiting charge is carried out to lithium ion battery, this The charging current in stage is typically set to 0.1C, and in the present embodiment, the pre-charge pressure may be configured as 3V.Constant-current charging phase: When the voltage of lithium ion battery gradually rises and exceedes pre-charge pressure, using the maximum current of design, (Fig. 2 charging current curves are most The horizontal linear section of eminence) lithium ion battery is charged, until the voltage of lithium ion battery is raised to nominal ceiling voltage Untill value.Constant voltage charging phase:Rising to nominal ceiling voltage in the voltage of lithium ion battery, (Fig. 2 charging voltages curve is most The horizontal linear section of eminence) when, lithium ion battery is charged using the nominal ceiling voltage;This stage is charged into electricity The electric current in pond can be gradually reduced, and when being reduced to cut-off charging current, whole charge will stop.From the electricity of lithium ion battery 10 From the aspect of growth, charging stage is most slow, and constant-current charging phase is most fast, and constant voltage charging phase starts very soon, later due to charging electricity Stream is gradually reduced, and electricity rate of rise is also gradually slack-off.
The reminding module 40, for prompting lithium ion battery 10 to have been filled with electricity, such as send prompt tone or use light Prompted, can also be shown by figure or word.In the present embodiment, the reminding module 40 is the display of mobile terminal Screen, it can show that lithium ion battery 10 has been filled with electricity.
The processing module 30, capacity is declared for compare the charge capacity of lithium ion battery 10 and lithium ion battery 10 The size of (preset capacity), the charge capacity be more than or equal to it is described declare capacity when, by reminding module 40 prompt lithium from Sub- battery 10 has been filled with electricity;Wherein, the lithium ion battery declare capacity be less than lithium ion battery nominal capacity.This implementation In example, the processing module 30 is processor.Declare that capacity is less than the nominal capacity of lithium ion battery due to lithium ion battery, The time of constant-voltage charge is shortened, this method can improve charging rate in the case of equal charge capacity.
