The terminal of indication in the method for a kind of compatible two kinds of battery chargers that present embodiment provides and a kind of terminal, comprising: mobile phone, panel computer, digital camera, notebook computer, PDA, MP3 etc. are applicable to the terminal of the described method of present embodiment.The below is described embodiments of the invention with reference to the accompanying drawings take mobile phone as example.Referring to Fig. 1, manage the first embodiment schematic flow sheet of the method for battery charger for the present invention.The method of the described management battery charger of present embodiment comprises step:
S101 according to the identification code of the battery that inserts 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.
The below specifically describes explanation as an example of this terminal of mobile phone example.The battery of indication in the present embodiment comprises two class batteries: former emblem mark distribution pond and non-original factory standard configuration battery.
Former emblem mark distribution pond can comprise multiple different battery, and these batteries have different full-load voltages.For example full-load voltage is arranged is that battery and the full-load voltage of 4.2V is the battery of 4.35V in the former emblem mark distribution pond of mobile phone.This type of battery, in the design of battery of mobile phone, when producing, a fixing ID identification module can be mixed in the inside of battery by the original production producer of battery, and this ID identification module internal battery ID is referred to as the standard configuration battery identification code of mobile phone.In the specific implementation, the inner ID identification module that is equipped with in this type of former emblem mark distribution pond may be some resistance, comprise the identification module that conventional, electric-resistance or temperature resistance constant resistance are made, the perhaps identification module that forms of other some transducers, or some encrypt IC(Integrated Circuit, integrated circuit) identification module made of chip, the perhaps identification module made of other method.Mobile phone adopts corresponding recognition methods, for example by the ID pin of battery, the judgement read method of resistance, the perhaps read method of sensing data, perhaps the methods such as read method of IC chip data are obtained the id information data of this battery, detect, identify the type of this battery.Wherein, the battery ID information that comprises 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 the ceiling voltage of battery charging, battery capacity.Mobile phone can be by detecting the ID of this type of battery of mobile phone, according to the ID data that detect, comprise: the model of above-mentioned battery, the full-load voltage of battery and the battery ID information datas such as capacity of battery, judge the type of this battery, for example, detect to judge that by mobile phone this battery is that full-load voltage is that battery or the full-load voltage of 4.2V is the battery of 4.35V.Mobile phone detects after the full-load voltage of the battery that inserts mobile phone, then can calculate according to the full-load voltage of battery the maximum charging voltage of this battery, and obtaining then can be according to this voltage to battery coupling Charge Management program after 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, it also is the maximum charging voltage that battery can bear, if give this battery charging with the charging voltage that surpasses this voltage range, then may affect battery life, perhaps cause easily 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 less than 0.15V.For example, when the full-load voltage of battery is 4.2V, be that the voltage of battery when being full of electricity is when being 4.2V, the maximum charging voltage of battery then is that 4.2V is to a magnitude of voltage between the 4.35V, wherein, optimal value can be 4.25V to 4.3V, namely is charged as a rational charging scope for this battery with the voltage in this scope, the life-span of battery can be guaranteed, the Accidental occurrences 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 then be 4.35V to a magnitude of voltage between the 4.5V, wherein, optimal value can be 4.4V to 4.45V, namely is charged as a rational charging scope for this battery with the voltage in this scope.
Non-original factory standard configuration battery comprises that the cellphone subscriber passes through height imitative battery, the perhaps former emblem mark distribution pond of non-the mobile phones such as battery of other mobile phone models of this mobile phone model of third part purchase.May there be the battery ID identification module this class battery the inside, but this ID is ID corresponding to this battery self model, but not the former emblem mark of this mobile phone is joined battery ID, and perhaps this class battery the inside does not have the battery ID identification module.Because this type of battery do not have the ID identification module, perhaps the ID of this type of battery is not that the former emblem mark of this mobile phone is joined battery ID, so this mobile phone None-identified goes out such battery types.This class non-original factory standard configuration battery may comprise that also ceiling voltage is the battery of A and two kinds of batteries of battery that ceiling voltage is B, for example the imitative 4.2V battery of the height of this mobile phone and 4.35V battery.Because mobile phone detects the type of None-identified battery by ID, so can't judge by detecting battery ID the full-load voltage of such non-original factory standard configuration battery, also just can't calculate the maximum charging voltage information of this battery.
S102, if acquire the maximum charging voltage information of described battery, then give described battery charging according to the corresponding battery charging management program of the maximum charging voltage information matches of described battery, guarantee that the maximum charging voltage of described battery charging management program output is not higher than the maximum charging voltage of described battery.
In S101, mobile phone acquires the full-load voltage that inserts the battery in the mobile phone according to the battery identification code data that detects, and calculates the maximum charging voltage of battery according to the full-load voltage of the battery that acquires again.The maximum charging voltage that mobile phone calculates battery then can charge to this battery according to the corresponding battery charging management program of the maximum charging voltage information matches of battery afterwards.
In the specific implementation, mobile phone can be according to the type design of battery of mobile phone, the battery charging management program of N grade of storage, wherein, the battery charging management program of N 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 of the battery charging management program of maximum output voltage value maximum can be set to the first battery charging management program, the maximum output voltage value is less than the maximum charging voltage of the first battery charging management program output second battery charging management program that is set to greater than the maximum charging voltage of other battery management programs outputs, the grade of the battery charging management program of maximum output voltage value minimum is the lowest class battery charging management program, by that analogy, set the grade of each battery charging management program.
But mobile phone obtains after the maximum charging voltage of the battery that inserts mobile phone the then maximum charging voltage of control cell and the ceiling voltage of the first battery charging management program output, judges whether the maximum charging voltage of this battery is not less than the maximum charging voltage of the first battery charging management program output.If the maximum charging voltage of this battery is not less than the maximum charging voltage of the first battery charging management program output, the first battery charging management program of then calling guarantees that to this battery charging the maximum charging voltage of described battery charging management program output is not higher than the maximum charging voltage of described battery.If the maximum charging voltage of this battery is lower than the ceiling voltage of the first Charge Management program output, 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 of the second battery charging management program output, the second battery charging management program of then calling guarantees that to this battery charging the maximum charging voltage of described battery charging management program output is not higher than the maximum charging voltage of described battery.If the maximum charging voltage of this battery is lower than the ceiling voltage of the second Charge Management program output, then continue the maximum charging voltage of the battery charging management program output of the maximum charging voltage of this battery of contrast and other grades, the battery charging management programs such as high charge management voltage such as the maximum charging voltage of the 3rd battery charging management program output, the output of the 4th battery charging management program, until match corresponding battery charging management program, and call corresponding battery charging management program to this battery charging.
The below take the battery charging management program of embedded in mobile phone be two as example, illustrate the matching process that the above-mentioned corresponding battery charging management program of the maximum charging voltage information matches according to battery charges the battery.For example, be that full-load voltage is 4.2V when mobile phone gets access to the battery that inserts mobile phone, the magnitude of voltage that the upper bias-voltage of battery can be set is 0.1V, the maximum charging voltage that then can calculate this battery is 4.3V.If the maximum charging voltage of the first battery charging management program output is 4.45V, the maximum charging voltage of the second battery charging management program output is 4.25V, maximum charging voltage 4.3V according to this battery is lower than 4.4V, be higher than 4.25V, can judge that the maximum charging voltage that obtains this battery is higher than the maximum charging voltage of the second battery charging management program output, namely the maximum charging voltage of this battery is not less than the maximum charging voltage of the second battery charging management program output, and the second battery charging management program of then calling is to this battery charging.During constant voltage charge, the second battery charging management program can be exported 4.2V and charge to this battery to a stable voltage between the 4.25V, guarantees that the maximum charging voltage of the second battery charging management program output is not higher than the maximum charging voltage of this battery.If it is 4.35V that mobile phone gets access to the full-load voltage of the battery that inserts mobile phone, the maximum charging voltage that then can calculate this battery is 4.45V, can mate to such an extent that the maximum charging voltage 4.45V of this battery equals the ceiling voltage of the first battery charging management program output according to the maximum charging voltage of this battery, namely the maximum charging voltage of this battery is not less than the ceiling voltage of the first battery charging management program output, and the first battery charging management program of then calling is to this battery charging.During constant voltage charge, the first battery charging management program can be exported 4.4V and charge to this battery to a stable voltage between the 4.45V, guarantees that the maximum charging voltage of the first battery charging management program output is not higher than the maximum charging voltage of this battery.
S103 if obtain full-load voltage 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 inserts mobile phone as the cellphone subscriber is the battery of the imitative battery of height of cellphone subscriber's this mobile phone of passing through third part purchase or other mobile phone models, mobile phone detects this type of non-original factory standard configuration battery of None-identified by battery ID, and because this type of battery of mobile phone None-identified, so also battery types of this type of battery of None-identified, can't learn the full-load voltage of this battery, also can't obtain the maximum charging voltage of this battery.In the specific implementation, the cellphone subscriber may be because professional knowledge be inadequate or careless, the maximum charging voltage that battery is inserted output is greater than charging in charging circuit corresponding to the battery charging management program of the maximum charging voltage of this battery, for example, be that to be inserted into maximum output voltage be to charge in charging circuit corresponding to the battery charging management program of 4.35V for the battery of 4.2V with full-load voltage.Because the output voltage of circuit is higher than the maximum charging voltage of battery, the life-span of battery may be shortened if charge the battery with such circuit, even battery explosion can be caused, destroy mobile phone, endanger cellphone subscriber's safety.In order to guarantee the life-span of battery, avoid Accidental occurrence, ensure cellphone subscriber's safety, when mobile phone detects, obtains full-load voltage information less than the battery that inserts mobile phone, the maximum charging voltage of then giving tacit consent to this type of battery is not less than the maximum charging voltage of the battery charging management program output of the lowest class, the battery charging management program of the lowest class that the mobile phone Automatically invoked is corresponding is given this battery charging, 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.For example, if the maximum charging voltage of the battery charging management program of the lowest class output is 4.2V, then when mobile phone obtains full-load voltage less than the battery that inserts mobile phone, the full-load voltage that mobile phone is then given tacit consent to this battery is 4.2V, and the battery charging management program of calling the lowest class is given this battery charging.
The ID pin of the battery of present embodiment mobile phone by inserting mobile phone detects the ID of battery, identifies the type of battery according to the battery ID data that detect, and calls corresponding battery charging management program according to the type of battery again and charges the battery.When constant voltage charge, the battery charging management program automatically corresponding charging voltage of output is given corresponding battery charging.The method that the embodiment of the invention is described both can be charged by polytype battery, simultaneously can also avoid charging the battery with excessive voltage, avoid the Accidental occurrences such as mobile phone blast, increased the type of the applicable battery of mobile phone, strengthened the fail safe that battery of mobile phone uses and charges.
