For making object of the present invention, technical scheme and advantage clearly, clearly, developing simultaneously referring to accompanying drawing, the present invention is described in more detail for embodiment.Should be appreciated that specific embodiment described herein only in order to explain the present invention, be not intended to limit the present invention.
First preferred embodiment of a kind of battery discriminating method based on mobile terminal of the present invention, as shown in Figure 1, comprises step:
In step S100, mobile terminal-opening process, detect the electric current exported from battery and be designated as the first electric current, and record the first magnitude of voltage on powered battery pin.
During concrete enforcement, because identifying the battery which supplier produces, therefore this process is generally carried out in the start process of mobile terminal.Detect that namely start detects the electric current that battery exports, and be designated as the first electric current by what now record from the electric current of battery output, the magnitude of voltage simultaneously recorded on powered battery pin is the first magnitude of voltage.
Also comprise before described step S100:
The battery parameter of battery supplier stores by mobile terminal in advance.
During concrete enforcement, mobile terminal produce time just the battery parameter of the supplier of battery, comprise discharge curve, the battery parameters such as battery power amount calculation method store, detect the supplier of battery for mobile terminal after, the parameter of correspondence is loaded, calculates battery electric quantity number percent more accurately.
Step S200, when detecting different from described first electric current from cell output current, recording the electric current exported from battery is the second electric current, and records the second magnitude of voltage on powered battery pin.
During concrete enforcement, the electric current of mobile terminal to battery detects in real time, when detecting that the electric current that battery exports is different from the first electric current recorded before, the electric current write down now is the second electric current, and the magnitude of voltage recorded on now powered battery pin is the second magnitude of voltage.
Step S300, calculate the internal resistance of cell and current battery level according to the first electric current, the first magnitude of voltage and the second electric current, the second magnitude of voltage.
Be illustrated in figure 2 the schematic equivalent circuit of battery of the present invention; When anode outflow size is the electric current of X1, the voltage of anode is Y1; When anode outflow size is the electric current of X2, the voltage of anode is Y2; Therefore, the internal resistance of cell and current electricity can be solved as voltage V according to following formula:
Y1 = X1 * R + V,
Y2 = X2 * R + V,
Obtain
V = (X1*Y2 – X2*Y1)/(X1 - X2),
R = (Y1 – Y2)/(X1 – X2)。
Step S400, obtain current battery temperature, and compare according to the internal resistance of cell obtained and current battery level and the battery parameter of battery supplier that prestores, judge the supplier of described battery.
During concrete enforcement, step S400 specifically comprises:
By the thermistor installed on Mobile terminal main board, obtain the Current Temperatures of battery according to the resistance process of thermistor; During concrete enforcement, be illustrated in figure 4 the schematic diagram of the circuit being obtained temperature by thermistor, an a thermistor Rt and one fixed resistance Rc is had in temperature acquisition cuicuit, by obtaining voltage Vt1, Vt2, resistance Rt=Rc * (Vt1 – the Vt2)/Vt2 of thermistor just can be obtained; Then Current Temperatures is obtained according to the corresponding relation of temperature and resistance value; Described temperature with the pass of thermosensitive resistance is: preserve the thermosensitive resistance that each temperature is corresponding in the terminal, therefore, obtains thermosensitive resistance and just can obtain Current Temperatures T.
Contrast according to the Current Temperatures obtained, internal resistance of cell R and current battery level V and the battery parameter prestored in the terminal, judge the supplier of described battery.
During concrete enforcement, internal resistance of cell R and battery manufacturing process, material etc. have relation; And different battery supplier, its manufacturing process, material are incomplete same, therefore can be identified the battery of different battery manufacturers produce by the internal resistance of cell; In addition, under different temperatures, different cell voltage, the internal resistance of cell is also not identical; Therefore, step S400 is by obtaining Current Temperatures, and the cell voltage V obtained in step S300, internal resistance of cell R, just can know that this battery is which supplier produced.

During concrete enforcement, there are two kinds of computing method.As shown in Figure 3, there is a sampling resistor Rs mobile terminal inside, and this resistance is fixed; After start being detected, the voltage at acquisition sampling resistor Rs two ends is also made difference and is obtained divided by Rs the electric current X1 flowing through sampling resistor Rs, and obtains the voltage Y1 on anode simultaneously; Afterwards, the voltage at acquisition sampling resistor Rs two ends is also made difference and is obtained divided by Rs the electric current X2 flowing through sampling resistor Rs, if X2 and X1 is equal, then the voltage at acquisition sampling resistor Rs two ends is also made difference and is obtained divided by Rs the electric current X2 flowing through sampling resistor Rs, until X2 and X1 is unequal, and obtain the voltage Y2 on anode simultaneously; Computing module 20 obtains following two formulas according to X1, Y1, X2, Y2 and calculates internal resistance of cell R and current battery level V:
Y1 = X1 * R + V,
Y2 = X2 * R + V,
Obtain
V = (X1*Y2 – X2*Y1)/(X1 - X2),
R = (Y1 – Y2)/(X1 – X2)。
Calculate the second method of cell voltage V and internal resistance of cell R: be the same because of the change of power consumption in mobile terminal each time start process, therefore, only need to test in start process the electric current of the different time point of two electric currents exported from battery, and the voltage obtained on the anode of these two time points also can calculate internal resistance of cell R and current battery level V; Such as, the electric current exported from battery when test obtains mobile terminal-opening the 1st second when mobile terminal is produced is X1, the electric current exported from battery when test obtains mobile terminal-opening the 2nd second when mobile terminal is produced is X2, obtain anode voltage Y1 when mobile terminal-opening the 1st second, the 2nd second time, obtain anode voltage Y2; Obtain following two formulas according to X1, Y1, X2, Y2 and calculate internal resistance of cell R and current battery level V:
Y1 = X1 * R + V,
Y2 = X2 * R + V,
Obtain
V = (X1*Y2 – X2*Y1)/(X1 - X2),
R = (Y1 – Y2)/(X1 – X2)。
