Description of drawings
Fig. 1 is a hardware configuration schematic diagram of the present invention.
Fig. 2 is the state exchange flow chart of communication terminal double-battery charge and power supply method among the present invention.
Embodiment
Provide preferred embodiment of the present invention below in conjunction with accompanying drawing, to describe technical scheme of the present invention in detail.
As Fig. 1, the related hardware of mobile communication terminal is designed in this method: two battery interfaces 11 are housed on the mainboard of mobile phone 1, corresponding PIN pin connection reaches fills power supply circuits 12 accordingly, this fill power supply circuits 12 be connected with one fill the power supply switching device shifter 13, this device comprises with lower module: first control module 131, control first powered battery, second battery is idle; Voltage logging modle 132 writes down the voltage of two batteries; Judge module 133 when first cell voltage does not satisfy condition of power supply, has judged whether that charger inserts; Second control module 134 if there is charger to insert, controlled first battery and is powered simultaneously and charge, and second battery continues idle; When first battery is full of electricity and second battery underfill when electricity, by first powered battery, second battery charge.For convenience of explanation, two batteries are represented with A battery and B battery respectively.They are separate, work independently.Use for them is to be controlled by the software on the mobile phone, specifically comprises two aspects:
The one, power supply selection problem, elder generation's default setting piece powered battery when start is as B, when B does not exist (promptly not inserting) or not enough certain the thresholding low-voltage V of cell voltage LThe time, then can not power, and power by A by B.In mobile phone used, electric weight reduced gradually, when the battery that uses is lower than V LThe time, also automatically switch to another piece battery.
Wherein the switching condition of battery is that voltage is lower than V L, so the voltage of two batteries of needs record.Can when start, just note the voltage of two batteries, and monitor the battery of current use, when satisfying above-mentioned switching condition, just automatically switch.
It two is charging problems, after the user inserts charger, just begins the battery charge to power supply, is assumed to be B, when B battery voltage is higher than certain thresholding high voltage V HThe time, represent that promptly B battery is full of, judge whether A exists this moment, if exist then judge the A cell voltage again, if be higher than V HExpression A is in the full state of electric weight, then stops charging process; If the A electric weight is discontented, then switch to charging, up to being full of to A.When starting shooting too, the voltage of A battery just notes.
For charging process, also to consider the power consumption problem of mobile communication terminal in the charging process.After charging is full of, need judge the electric weight of the supplying cell of current use, if less than V H, then switch to the supplying cell charging, otherwise complete charge.
When running into accident, as pull out battery, software can be received the interruption of being sent by system, and can switch at once by another piece powered battery this moment, to guarantee that mobile phone does not cut off the power supply.
Circuit and method for powered battery and charging all adopt existing technical scheme, do not give unnecessary details at this.
Below in conjunction with Fig. 2, introduce the flow process of method of the present invention in detail, U among the figure aAnd U bThe voltage of representing battery A and B respectively; V LExpression thresholding low-voltage, cell voltage is lower than V LThe time cisco unity malfunction; V HExpression thresholding high voltage, cell voltage is V HThe expression battery is for being full of electricity condition.
As shown in Figure 2, acquiescence begins power supply by A or B during start, is powered by A in the present embodiment.Need to prove that two battery A and B in this flow chart can replace mutually, if use the B battery power supply during start, then only is that A and B are exchanged among the figure, and its switching principle is the same, so the wherein a kind of route of scheme that only drawn among this figure.Rectangle frame is represented each state that battery A, B are combined among the figure, and diamond is represented the switching condition between each state, and concrete steps are as follows.
Step 100, if the A cell voltage meets condition of power supply, i.e. U a＞thresholding low-voltage V L, this V LBe a benchmark, work as U aDuring greater than this benchmark, then by A power supply start, this moment, B battery was idle, and noted A, the voltage of B battery.
Step 101 when the A cell voltage is not enough, judges whether to be inserted with charger.If be not inserted with charger, then be converted to power supply by B, promptly enter step 102.Judge U afterwards bWhether less than V L, when the result is "Yes", entering step 103, A and B all stop power supply; When the result is "No", return step 102.
On the basis of step 101, if insert charger this moment, then can give supplying cell A charging, promptly the A battery was powered simultaneously and was charged, and promptly enters step 104 still by the A powered battery this moment.
Step 105 is when the full condition of voltage conforms charging that is charged to A is U a＞thresholding high voltage V HThe time, then A stops charging, keeps power supply.
On the basis of step 105, judge U bWhether less than V HIf the result is a "Yes", then enters step 106, the B charging; If the result is a "No", then enter step 107, B stops charging.
On the basis of step 107, judge U aWhether less than V HIf the result is a "Yes", then enters step 108, A charging and power supply, B is idle; If the result is a "No", enter step 109, A and B all are full of electricity, and charging process finishes, and returns step 100 afterwards.
In the above-mentioned steps, when extracting a battery, automatically switch to an other powered battery.
If the B battery power supply is used in start, then A among the figure and B exchange are got final product, do not give unnecessary details at this.
Though more than described the specific embodiment of the present invention, it will be understood by those of skill in the art that these only illustrate, under the prerequisite that does not deviate from principle of the present invention and essence, can make numerous variations or modification to these execution modes.Therefore, protection scope of the present invention is limited by appended claims.
