S101, according to the identification code of the battery of insertion terminal, obtains the full-load voltage of described battery, calculates the maximum charging voltage information of described battery according to the full-load voltage of described battery.
Explanation is specifically described below for this terminal of mobile phone.The battery of indication in the present embodiment, comprises two class batteries: genuine standard configuration battery and non-original factory standard configuration battery.
Genuine standard configuration battery can comprise multiple different battery, and these batteries have different full-load voltages.It is the battery of 4.35V that the genuine standard configuration battery of such as mobile phone has full-load voltage to be the battery of 4.2V and full-load voltage.This type of battery, battery of mobile phone design, produce time, a fixing ID identification module can be mixed by the original production producer of battery in the inside of battery, this ID identification module internal battery ID, is referred to as the standard configuration battery identification code of mobile phone.In specific implementation, the ID identification module that this type of genuine standard configuration inside battery is equipped with may be some resistance, comprise the identification module that the resistance such as conventional, electric-resistance or temperature resistance is made, or the identification module of other some transducers composition, or some encryptions IC (Integrated Circuit, integrated circuit) identification module made of chip, or the identification module that other method is made.Mobile phone, by the ID pin of battery, adopts corresponding recognition methods, such as, the judgement read method of resistance, or the read method of sensing data, or the method such as the read method of IC chip data obtains the id information data of this battery, detects, identifies the type of this battery.Wherein, the battery ID information comprised in the ID identification module of battery can comprise: the model of battery plate, battery, battery charging voltage, i.e. the battery parameter information such as ceiling voltage, battery capacity of battery charging.Mobile phone can by detecting the ID of this type of battery of mobile phone, according to the ID data detected, comprise: the model of above-mentioned battery, the battery ID information datas such as the full-load voltage of battery and the capacity of battery, judge the type of this battery, such as, detected by mobile phone and judge this battery to be full-load voltage be the battery of 4.2V or full-load voltage is the battery of 4.35V.Mobile phone then can calculate the maximum charging voltage of this battery after the full-load voltage of the battery inserting mobile phone being detected according to the full-load voltage of battery, then can according to this voltage to battery coupling Charge Management program after obtaining the maximum charging voltage information of this battery.The maximum charging voltage of battery is that the full-load voltage of battery adds the magnitude of voltage that bias-voltage obtains, also be the maximum charging voltage that battery can bear, if with exceeding the charging voltage of this voltage range to the charging of this battery, then may affect battery life, or easily cause the safety problems such as battery explosion.Wherein, the full-load voltage of battery is the magnitude of voltage of battery when being full of electricity, and the magnitude of voltage of upper bias-voltage can be greater than 0V, and is less than 0.15V.Such as, when the full-load voltage of battery is 4.2V, namely when voltage when battery is full of electricity is 4.2V, the maximum charging voltage of battery is then a magnitude of voltage between 4.2V to 4.35V, wherein, optimal value can be 4.25V to 4.3V, is namely charged as a rational chargeable range to this battery with the voltage within the scope of this, the life-span of battery can be ensured, the unexpected generations such as mobile phone blast can be prevented again.When the full-load voltage of battery is 4.35V, the maximum charging voltage of battery is then a magnitude of voltage between 4.35V to 4.5V, and wherein, optimal value can be 4.4V to 4.45V, is namely charged as a rational chargeable range to this battery with the voltage within the scope of this.
Non-original factory standard configuration battery cellphone subscriber imitates battery by the height of this mobile phone model of third part purchase, or the genuine standard configuration battery of non-the mobile phone such as the battery of other mobile phone models.May have battery ID identification module inside this kind of battery, but this ID is the ID that to be self model of this battery corresponding, but not the genuine standard configuration battery ID of this mobile phone, or there is no battery ID identification module inside this kind of battery.Because this type of battery does not have ID identification module, or the ID of this type of battery is not the genuine standard configuration battery ID of this mobile phone, so this mobile phone None-identified goes out such battery types.This kind of non-original factory standard configuration battery also may comprise battery two kinds of batteries that battery that ceiling voltage is A and ceiling voltage are B, and the height of such as this mobile phone imitates 4.2V battery and 4.35V battery.Because mobile phone is by the type of ID detection None-identified battery, so the full-load voltage of such non-original factory standard configuration battery cannot be judged by detecting battery ID, the maximum charging voltage information of this battery also just cannot be calculated.
S102, if acquire the maximum charging voltage information of described battery, then give the charging of described battery according to the maximum charging voltage information matches corresponding battery charging management program of described battery, guarantee that maximum charging voltage that described battery charging management program exports is not higher than the maximum charging voltage of described battery.
In S101, mobile phone, according to the battery identification code data detected, acquires the full-load voltage of the battery inserted in mobile phone, then calculates the maximum charging voltage of battery according to the full-load voltage of the battery acquired.Mobile phone then can give the charging of this battery according to the corresponding battery charging management program of the maximum charging voltage information matches of battery after calculating the maximum charging voltage of battery.
In specific implementation, mobile phone can according to the type design of battery of mobile phone, store the battery charging management program of N number of grade, wherein, the battery charging management program of N number of grade is at least the battery charging management program of two grades, and wherein the maximum output voltage of the battery charging management program of each grade is different, the grade that maximum output voltage is worth maximum battery charging management program can be set to the first battery charging management program, maximum output voltage value be less than first battery charging management program export maximum charging voltage be greater than other battery management programs export maximum charging voltage be set to the second battery charging management program, the grade that maximum output voltage is worth minimum battery charging management program is the lowest class battery charging management program, by that analogy, set the grade of each battery charging management program.
Mobile phone then can the ceiling voltage that exports of the maximum charging voltage of control cell and the first battery charging management program after obtaining the maximum charging voltage of the battery inserting mobile phone, judges the maximum charging voltage whether maximum charging voltage of this battery is not less than the first battery charging management program and exports.If the maximum charging voltage of this battery is not less than the maximum charging voltage that the first battery charging management program exports, first battery charging management program of then calling, to the charging of this battery, guarantees that maximum charging voltage that described battery charging management program exports is not higher than the maximum charging voltage of described battery.If the ceiling voltage that the maximum charging voltage of this battery exports lower than the first Charge Management program, then continue the maximum charging voltage of this battery of contrast and the maximum charging voltage of the second battery charging management program output, judge whether the maximum charging voltage of this battery is not less than the maximum charging voltage of the second battery charging management program output.If the maximum charging voltage of this battery is not less than the maximum charging voltage that the second battery charging management program exports, second battery charging management program of then calling, to the charging of this battery, guarantees that maximum charging voltage that described battery charging management program exports is not higher than the maximum charging voltage of described battery.If the ceiling voltage that the maximum charging voltage of this battery exports lower than the second Charge Management program, then continue the maximum charging voltage that the contrast maximum charging voltage of this battery exports with the battery charging management program of other grades, the battery charging management programs such as the most high charge management voltage that the maximum charging voltage that such as the 3rd battery charging management program exports, the 4th battery charging management program export, until match corresponding battery charging management program, and call corresponding battery charging management program to the charging of this battery.

S103, if the full-load voltage obtaining less than described battery, then calls the battery charging management program of the lowest class to described battery charging.
In S101, when the battery that cellphone subscriber inserts mobile phone be cellphone subscriber imitate the battery of battery or other mobile phone models by the height of this mobile phone of third part purchase time, mobile phone detects this type of non-original factory standard configuration battery of None-identified by battery ID, and due to this type of battery of mobile phone None-identified, therefore the battery types of also this type of battery of None-identified, the full-load voltage of this battery cannot be learnt, also cannot obtain the maximum charging voltage of this battery.In specific implementation, cellphone subscriber may because professional knowledge be inadequate or careless, battery is inserted the maximum charging voltage exported to be greater than in charging circuit corresponding to the battery charging management program of the maximum charging voltage of this battery and to charge, such as, be that to be inserted into maximum output voltage be charge in charging circuit corresponding to the battery charging management program of 4.35V for the battery of 4.2V by full-load voltage.Because the output voltage of circuit is higher than the maximum charging voltage of battery, if charged the battery with such circuit to shorten the life-span of battery, even can cause battery explosion, destroy mobile phone, the safety of harm cellphone subscriber.In order to ensure the life-span of battery, avoid unexpected generation, ensure the safety of cellphone subscriber, when mobile phone detects, obtains less than when inserting the full-load voltage information of battery of mobile phone, the maximum charging voltage that the battery charging management program that the maximum charging voltage then giving tacit consent to this type of battery is not less than the lowest class exports, the battery charging management program of the lowest class that mobile phone Automatically invoked is corresponding gives the charging of this battery, guarantees that the maximum charging voltage of the battery charging management program output of the lowest class is not higher than the maximum charging voltage of this battery.Such as, if the maximum charging voltage that the battery charging management program of the lowest class exports is 4.2V, then when mobile phone obtains the full-load voltage less than the battery inserting mobile phone, the full-load voltage that this battery then given tacit consent to by mobile phone is 4.2V, and the battery charging management program calling the lowest class is charged to this battery.
The present embodiment mobile phone detects the ID of battery by the ID pin inserting the battery of mobile phone, identifies the type of battery according to the battery ID data detected, then calls corresponding battery charging management program according to the type of battery and charge the battery.When constant voltage charge, battery charging management program can export corresponding charging voltage automatically to the charging of corresponding battery.The method that the embodiment of the present invention describes both can be charged by polytype battery, can also avoid charging the battery with excessive voltage simultaneously, avoid the unexpected generations such as mobile phone blast, add the type being suitable for battery of mobile phone, strengthen the fail safe that battery of mobile phone uses and charges.
