Embodiment
Consulting shown in Fig. 1, is the system architecture diagram of quick charging system preferred embodiment of the present invention.In the present embodiment, described quick charging system 10 is installed and is run in mobile device 1.This mobile device 1 also include but not limited to, storage device 11, processor 12, display unit 13, temperature sensor 14 and battery 15.Described storage device 11 is for storing program code and the data information of quick charging system 10, this storage device 11 can be the internal memory of mobile device 1 itself, also can be external memory card, as SD card (SecureDigitalCard, safe digital card) etc.Described display unit 13 is for showing the information such as the result of charging, and this display unit 13 can be touch-screen etc.The variations in temperature of battery 15 when described temperature sensor 14 charges for mobile device described in detecting real-time 1, the temperature of such as battery 15 raises or reduces how many degrees Celsius etc.Described mobile device 1 can be the portable electric appts such as mobile phone, panel computer.
In the present embodiment, when mobile device 1 charges, described quick charging system 10 can provide two kinds of charge modes, and one is normal charge mode, and one is fast charge mode.When selecting fast charge mode, described quick charging system 10 utilizes temperature sensor 14 to obtain the temperature value of the battery 15 of mobile device 1, and the accessible pairs of maximum charging current values of this mobile device 1 under inquiring about temperature value described in charging current and battery temperature contingency table, and then the charging current of described mobile device 1 is adjusted to this pairs of maximum charging current values, make the battery 15 of described mobile device 1 within the shortest time, fill as far as possible many electricity fast with.
Consulting shown in Fig. 2, is the functional block diagram of quick charging system preferred embodiment of the present invention.In the present embodiment, described quick charging system 10 can be divided into one or more module, described one or more module is stored in described storage device 11, and be configured to be performed by one or more processor (the present embodiment is a processor 12), to complete the present invention.Such as, consult shown in Fig. 2, described quick charging system 10 is divided into acquisition module 101, enquiry module 102 and adjustment module 103.Module alleged by the present invention is the program segment that can complete a specific function, is more suitable for for describing the implementation of software in mobile device 1 than program, and the detailed functions about each module is described specifically in the flow chart of Fig. 3 later.
Consulting shown in Fig. 3, is the flow chart of fast charge method preferred embodiment of the present invention.According to different demands, the execution sequence of the step in the flow chart shown in Fig. 3 can change, and some step can be omitted.
Step S21, when mobile device 1 enters fast charge mode, acquisition module 101 utilizes temperature sensor 14 with the temperature value of the battery 15 of mobile device 1 described in fixing frequency acquisition.Described frequency can be 5 minutes one inferior.
Step S22, enquiry module 102 inquires about the accessible pairs of maximum charging current values under described temperature value of mobile device 1 described in charging current and battery temperature contingency table.
In the present embodiment, the charging current of mobile device 1 and the contingency table of battery temperature is stored in described storage device 11.As shown in Figure 6, have recorded mobile device 1 accessible pairs of maximum charging current values when the temperature value of battery 15 changes described in reality test in this contingency table.Described enquiry module 102 utilizes look-up table to obtain in described contingency table accessible pairs of maximum charging current values under the described temperature value recorded.
Specifically, in the ordinary course of things, for cost-saving, the charging current value of the battery 15 that manufacturer all can limit mobile device 1 when charging is the several fixed values in different temperatures value interval.As shown in Figure 4, the charging current limited when dispatching from the factory for the battery 15 of mobile device 1 and the curve chart of battery temperature.In the figure, when battery temperature is 0 DEG C ~ 25 DEG C, the charging current value of described mobile device 1 is constant is 0.5C, and when battery temperature is 25 DEG C ~ 40 DEG C, the charging current value of described mobile device 1 is constant is 1C.Under normal circumstances, user carries out according to the charging current value limited during described dispatching from the factory, and the charging interval is long.
And in reality test, the relation of the charging current value of described mobile device 1 and the temperature of battery 15 is not step function as shown in Figure 4, but curved shape as shown in Figure 5.Known compared with Fig. 4, with the increase of temperature value, the pairs of maximum charging current values that described mobile device 1 can reach in actual use is all greater than the fixed value limited when dispatching from the factory.Totally it seems, the charging current fixed value limited when described mobile device 1 dispatches from the factory is only 50% ~ 80% of actual accessible most high charge current value.Can find out, if charged to the battery 15 of mobile device 1 by the charging current of reality and the curve chart of battery temperature, the charging interval will effectively be shortened.In other words, even if the charging namely carrying out the short period also can fill many electricity with.
Therefore, the present invention is according to the charging current of mobile device 1 in reality test and the curve chart of battery temperature, described mobile device 1 accessible pairs of maximum charging current values when the temperature value of battery 15 changes is associated with corresponding temperature value, is saved in storage device 11.
Step S23, adjustment module 103 regulates the charging current value of described mobile device 1, the pairs of maximum charging current values under making it reach described temperature value.
By above-mentioned steps, the present invention utilizes the temperature value of the battery of temperature sensor Real-time Obtaining mobile device, and the charging current value of described mobile device is adjusted to the pairs of maximum charging current values under this temperature value.Accelerate the charging rate of the battery of described mobile device, for user uses mobile device to provide convenient, improve Consumer's Experience.
Finally it should be noted that, above embodiment is only in order to illustrate technical scheme of the present invention and unrestricted, although with reference to above preferred embodiment to invention has been detailed description, those of ordinary skill in the art should be appreciated that and can modify to technical scheme of the present invention or be equal to the spirit and scope of replacing and should not depart from technical solution of the present invention.
