Description of drawings
Fig. 1 is hardware configuration schematic diagram of the present invention.
Fig. 2 is the state flow path switch figure 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.
Such as Fig. 1, the related hardware of mobile communication terminal is designed in this method: the mainboard at mobile phone 1 is equipped with two battery interfaces 11, corresponding PIN pin connection reaches fills power supply circuits 12 accordingly, this fills power supply circuits 12 and is connected with one and fills power switching device 13, this device comprises with lower module: the first control module 131, control the first powered battery, the second battery is idle; Voltage logging modle 132 records the voltage of two batteries; Judge module 133 when the first cell voltage does not satisfy condition of power supply, has judged whether that charger inserts; The second control module 134 if there is charger to insert, controlled the first battery and is powered simultaneously and charge, and the second battery continues idle; When the first battery is full of electricity and the second battery underfill when electricity, by the first powered battery, the charging of the second battery.For convenience of explanation, two batteries represent with A battery and B battery respectively.They are separate, work independently.Usefulness 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 such as B, when B does not exist (namely not inserting) or not enough certain the thresholding low-voltage V of cell voltage
LThe time, then can not be powered by B, and be powered by A.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 record 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 charging to power supply, is assumed to be B, when B battery voltage is higher than certain thresholding high voltage V
HThe time, representing that namely 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 the charging to A, until be full of.When starting shooting too, the voltage of A battery just records.
For charging process, also to consider the power consumption problem of mobile communication terminal in the charging process.After charging is full of, need to 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, and therefore not to repeat here.
Below in conjunction with Fig. 2, introduce in detail the flow process of method of the present invention, U among the figure
aAnd U
bThe voltage that represents respectively battery A and B; 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 only drawn wherein a kind of route of scheme among this figure.Rectangle frame represents each state that battery A, B are combined among the figure, and diamond represents the switching condition between each state, and concrete steps are as follows.
On the basis of step 101, if insert charger this moment, then can give supplying cell A charging, namely the A battery was powered simultaneously and was charged, and namely enters step 104 still by the A powered battery this moment.
On the basis of step 105, judge U
bWhether less than V
HIf the result is "Yes", then enters step 106, the B charging; If the result is "No", then enter step 107, B stops charging.
On the basis of step 107, judge U
aWhether less than V
HIf the result is "Yes", then enters step 108, A charging and power supply, B is idle; If the result is "No", enter step 109, A and B all are full of electricity, and charging process finishes, and returns afterwards step 100.
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, therefore not to repeat here.
Although 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 various changes or modifications to these execution modes.Therefore, protection scope of the present invention is limited by appended claims.
