Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more clear and clear, the present invention will be further described in detail below with reference to the accompanying drawings and examples. It should be understood that the specific embodiments described herein are for purposes of illustration only and are not intended to limit the scope of the invention.

Battery capacity description: the battery capacity comprises a battery design capacity and a battery actual capacity; design capacity of battery: the nominal capacity of the battery when leaving the factory is referred to as mAh or Ah, the unit is usually marked on battery label paper, the design capacity of the mobile phone battery in the past is different, although the new model of each year gradually increases the capacity, the increase amplitude is not high, and the reverse phenomenon can occur sometimes; actual capacity of the battery: the actual capacity of the battery can be said to be the maximum capacity at a certain moment, generally speaking, the actual capacity will be higher than the design capacity, but as the number of battery cycles increases, the actual capacity will decrease, that is, the actual capacity is a variable value, the most obvious difference between the two is that the design capacity is a fixed value, the actual capacity is a dynamic value, and the actual capacity will decrease slowly as the number of battery cycles increases, and the actual capacity is the battery capacity data that the user needs to pay attention to in short.
When the battery of the mobile phone of the user is charged and discharged for a long time, the actual capacity of the battery can be reduced, and the capacity parameter (namely the health degree) of the battery can be correspondingly set in the battery circuit, so that the battery protection board and the mobile phone circuit can control the charging time and process in each charging process, and the overcharging situation is reduced. Because the system makes misjudgment on the battery power (the stored charge and discharge information in the protection circuit is changed) in the process of multiple charge and discharge, the situation that the battery endurance time is shortened and the battery cannot be fully charged can occur. For example, if the battery is used for a period of time, the charging capacity of the battery may be reduced to 70%, and the battery capacity may be recorded in the protection plate of the battery and stored for the next charging limit through each charging and discharging process.
Application scenario 1: when a user changes a new mobile phone battery (in the prior art, the battery is changed only by changing the battery core, the protection circuit is not changed, and the data recorded by the protection circuit influences the charge amount), the health degree of the changed battery still is the charge-discharge capacity recorded in the battery protection circuit due to the binding action of the mobile phone and the battery protection circuit, for example, the charge-discharge capacity recorded in the protection circuit is 70%, so that in the actual charging process, the charging is stopped after 70% of the charge amount (the actual charge amount is, but the mobile phone is fully charged), so that the battery is safe, but the use of the actual capacity of the new battery cannot be ensured.
Specifically, a connection between a battery calibrator and the target battery is established, and battery information of the target battery is acquired, wherein the battery information comprises: cell capacity, raw battery health, battery charge, battery current, battery status, battery type, and battery voltage.
The capacity of the battery cell refers to the capacity (fixed value) of the battery cell for storing electric quantity; the original battery health degree refers to the current actual charge and discharge amount of the battery and is also a key point of updating and lifting in the invention; the battery power refers to the current power displayed on the mobile phone; the battery current refers to the current passing through a circuit in the charging and discharging process of the battery; the battery voltage refers to the voltage of a circuit in the charging and discharging process of the battery, and the battery state refers to some parameters of the battery, such as temperature, service life and service life; the battery type refers to the type of the battery adapted to the mobile phone.
The invention is based on a newly developed battery calibrator, comprising: calibration equipment host computer, battery calibration connector (many types of interfaces, preferably 6), calibration parameter setting button, start button, stop button, selection button, calibration state display window, display screen, buzzer prompt, radiator fan, casing, battery lock joint accessory etc..

When the battery capacity of the target battery needs to be repaired, firstly, the mobile phone model corresponding to the target battery is obtained, the target battery is connected to a battery calibration connection port of the battery calibrator according to the mobile phone model, connection between the target battery and the battery calibrator is established, battery information of the target battery is obtained by pressing a calibration parameter setting button on the battery calibrator, and the battery information is displayed through a display screen, for example, after the battery is connected with the battery calibrator, the display screen on the battery calibrator can display the health degree of the battery, if the health degree is 70%, battery repair can be performed, and the health degree can reach a preset health degree (such as 80% or 100%, and can be defined by a user himself).
Based on the battery information, the calibration parameters are set on the battery calibrator through rotating the calibration parameter setting button, the calibration parameters are stored, the battery repair instrument starts to work through the starting button, and a user can press the stopping button at any time to modify the calibration parameters.
And step S20, carrying out charging treatment on the target battery according to the calibration parameters, stopping charging when the battery information meets a first preset condition, and carrying out charging and standing after charging, wherein the charging treatment comprises charging and standing after charging.
Specifically, the target battery is charged according to the preset charging current of the calibration parameter, when the battery electric quantity of the target battery is detected to be full, a first battery current of the target battery is obtained, and whether the first battery current is smaller than the preset current is judged.
And when the first battery current is not smaller than the preset current, continuing to charge until the first battery current is smaller than the preset current.
And stopping charging when the first battery current is smaller than a preset current, and standing after charging after the target battery is stopped.
The method comprises the following specific steps:
1. the battery repairing instrument charges the independent battery through the set charging current.
2. When the battery capacity of the battery is full, detecting the charging current in the battery circuit, and if the charging current exists, proving that the charging capacity of the battery at the moment possibly does not reach the actual capacity of the battery, and further, charging can be continued.
3. When the charging current in the battery circuit is greater than the preset current, the battery is further charged until the charging current in the battery circuit is not greater than the preset current (the circuit proves that only a weak charging current, preferably less than 1 percent of the current exists in the circuit), and the battery is kept stand for a long time after charging (as seen, the battery charging stop needs to be met, the battery charge reaches 100 percent and the current in the battery circuit is less than 1 percent).
And S30, when the time for standing after charging reaches the first preset time, the charging treatment is completed, discharging treatment is carried out on the target battery according to the calibration parameters, and when the battery information meets the second preset condition, discharging is stopped, and standing after discharging is carried out, wherein the discharging treatment comprises discharging and standing after discharging.
Specifically, the time of standing after charging is detected, when the time of standing after charging reaches the preset time of standing after charging, the charging treatment is completed, and the target battery is discharged according to the preset discharging current of the calibration parameter.
And acquiring a second battery current and a battery voltage of the target battery, and judging whether the second battery current is smaller than a preset current and whether the battery voltage is smaller than a preset voltage.
And when the second battery current is not smaller than a preset current or the battery voltage is not smaller than a preset voltage, continuing to perform discharge treatment until the second battery current is smaller than the preset current and the battery voltage is smaller than the preset voltage.
And stopping discharging when the second battery current is smaller than a preset current and the battery voltage is smaller than a preset voltage, and standing after discharging when the target battery stops discharging.
The method comprises the following specific steps:
1. and when the standing time after charging reaches the preset time, the completion of the charging treatment is proved, and the target battery is subjected to discharging treatment according to the preset discharging current set on the calibration parameters.
2. And monitoring the battery current and the battery voltage of a circuit in the target battery in the discharging process, stopping discharging when the battery current is not more than a preset current and the battery voltage is not more than a preset voltage, and standing after discharging (as can be seen, the stopping of the discharging of the battery is required to be met, namely, the current in the battery circuit is very low and the voltage in the battery circuit is very low).
And S40, when the standing time after discharging reaches a second preset time, the discharging process is completed, whether the current battery health of the target battery reaches the preset battery health of the calibration parameters is judged in real time in the calibration process of the charging process and the discharging process, if so, the calibration is stopped and a prompt is sent out, and if not, the charging process and the discharging process are repeatedly carried out on the target battery until the current battery health of the target battery reaches the preset battery health.
Specifically, detecting the time of standing after discharging, and finishing the discharging treatment when the time of standing after discharging reaches the preset time of standing after discharging;
and acquiring the current battery health degree of the target battery in real time in the calibration process of the charging process and the discharging process, and judging whether the current battery health degree reaches the preset battery health degree or not.
And if not, carrying out charging treatment and discharging treatment again until the current battery health degree reaches the preset health degree.
And when the current battery health degree does not reach the preset battery health degree, storing the current battery health degree.

If yes, stopping the calibration process, controlling a calibration state display window of the battery calibrator to turn green, and controlling a buzzer prompter of the battery calibrator to give out prompt sound.
The method comprises the following specific steps:
1. when the standing time reaches the preset duration, the charge and discharge processes of steps S10-S40 are performed again, and an iterative loop process is performed, so that on one hand, the accidental situation that the battery capacity is increased in the charge process (the actual one-time charge and discharge process may be the process of occasionally measuring an error parameter) is avoided, and on the other hand, the battery capacity can only be increased by a small extent in each charge and discharge process (the record adjustment logic of the capacity parameter of the battery core of the automatic lifting battery is preset in the battery protection board, and the capacity parameter record of the battery protection board is automatically increased or decreased according to the step or step length), and in order to reach the preset battery capacity expected by the user, the battery capacity is required to be increased in stages by repeated iterations.
2. And detecting the health degree of the battery in real time in the process of repeated iteration charge and discharge, when the health degree of the target battery reaches the preset battery health degree, proving that the battery is updated at the moment (the battery health degree reaches the expected), directly stopping the calibration of the battery calibrator, and meanwhile, turning green a calibration state display window of the battery calibrator and sounding a buzzer prompt to prompt a user to take down the target battery.
Therefore, the method for carrying out iterative charge and discharge on the battery in the invention comprises the following steps: the charge-rest-discharge-rest is a period, the iterative mode is to perform periodic charge and discharge, and the information stored in the protection circuit in the battery is updated every time the charge and discharge period passes, and the health of the battery is continuously updated.
And after the target battery is subjected to iterative charge processing and discharge processing, if the current battery health degree is smaller than the original battery health degree, judging that the battery core of the target battery has faults.
The invention can also judge through the change condition of the battery health degree in the charging and discharging process, and can judge that the battery core of the battery has faults when the health degree capacity of the battery is continuously reduced along with the increase of the number of charging and discharging iterations.
In addition, the novel battery calibrator has the advantages that the number of the interfaces of the novel battery calibrator is preset (preferably 6), the two types of batteries are matched on each interface and are independently operated, the batteries with the preset number can be calibrated at the same time without mutual influence, the battery calibration efficiency is greatly improved, and compared with the technology in the prior art that only a single battery can be calibrated, the calibration efficiency is obviously higher.
Application scenario 2: in the prior art, when the battery leaves the factory, the health degree in the battery protection circuit is set to be a preset value (preferably 70%), if the health degree of the battery is required to be set to be 100%, the battery needs to be updated to the original factory, and the step S10-S40 is very troublesome, and the health degree of the battery of the mobile phone can be improved to be the preset health degree value (preferably 100%), so that the experience of updating the actual capacity of the battery by a user is facilitated.
The invention aims to update the original recording parameters of the old battery through a novel developed battery calibrator, namely, to modify the charge and discharge information stored in a protection circuit in the battery, and to stepwise improve the health degree of the battery through an iterative charge and discharge mode, and to replace the health degree information recorded in the original old battery, so as to achieve the effect of improving the actual capacity of the battery.
