To make the object, technical solutions and advantages of the present invention clearer, below in conjunction with drawings and the specific embodiments, to this
Invention is described in further detail.
According to an embodiment of the invention, providing a kind of management method of battery parameter for terminal.As shown in Figure 1,
Fig. 1 is the flow chart of the management method of battery parameter according to an embodiment of the invention.
Step S110 obtains the most recent parameters of battery by monitoring the working condition of battery.
The working condition of battery includes: charge and discharge time of battery, temperature, voltage, electric current etc., and monitoring state can be with
Form corresponding operating state data.
The most recent parameters of battery are the battery parameters for describing battery present behavior, comprising: the ageing parameter of battery, interior
Resistance, capacity, temperature-compensating, voltage and electricity the data such as corresponding relationship.Ageing parameter is for indicating the internal resistance of cell, capacity and electricity
The relationship of pond Degree of Ageing.Temperature-compensating is used to indicate the relationship of battery temperature and battery charging and discharging.
By continuing to monitor to cell operating status, the operating state data of battery can be obtained.By using preparatory
The learning algorithm (electricity algorithm) of setting, learns the operating state data of battery, may finally obtain the most recent parameters of battery.By
It is, for example, in the learning algorithm: the prediction algorithm of power consumption model and power loss, the backoff algorithm of temperature, cell degradation and study
Algorithm, filtering, sluggish smoothing algorithm etc., these learning algorithms are all the prior art, and this will not be repeated here.Further,
The working condition of above-mentioned monitoring battery, the most recent parameters for obtaining battery can be executed by terminal that battery is worked.
The present invention is according to every piece of individual cells monitoring state, and the operating state data of acquisition is more targeted, in turn
The battery parameter of acquisition is more accurate.Such as the working condition by monitoring the first battery, learn that the capacity of the first battery is
1700mAh learns that the capacity of the second battery is 1500mAh by monitoring the working condition of the second battery.
Step S120, by the most recent parameters storage of battery to server end.
Server is used to record the most recent parameters of muti-piece battery.Further, for every piece of battery, server can be with
The most recent parameters uploaded every time are recorded, also can recorde the most recent parameters that last time uploads.
At the time of obtaining most recent parameters, every the preset period or when the variation of the data in most recent parameters exceeds
When preset threshold value, most recent parameters are uploaded to server, to store most recent parameters.It will be appreciated by those skilled in the art that uploading
The condition of most recent parameters is without being limited thereto.Further, upload movement can be executed as the terminal locating for battery.
According to the unique identity code (Identification, ID) for being in advance battery-allocated, by the newest of battery
Parameter is stored to server end.Further, since battery can work in different terminals, in order to distinguish every block of electricity
The most recent parameters in pond are in advance the unique ID of every piece of battery-allocated.The identity code core in inside battery can be set in the ID
In piece.In this way, after battery work, it will be able to by the terminal recognition locating for it.Terminal can according to the ID of the battery read,
The most recent parameters of the ID are cached in local terminal.Server can also be according to the ID of battery, by the most recent parameters and its ID of every piece of battery
Corresponding storage.
The present embodiment is preferred, and when carrying out the default setting of battery, ID is arranged for battery.
The most recent parameters of every piece of battery are uploaded onto the server end, and are managed collectively by server, it can be to avoid being every piece
Voltameter built in battery reduces the cost of battery.
Step S130, when battery is reworked, according to the most recent parameters of the battery obtained from server end, newest terminal
The currently used battery parameter of system.
Battery, which is reworked, refers to battery again and is terminal power supply, such as: battery stops being that terminal is powered after terminal closedown,
After terminal is switched on again, battery is terminal power supply again.
When obtaining the most recent parameters of battery, most recent parameters corresponding with the ID of battery are obtained.Further, acquisition
Most recent parameters are that last time is uploaded onto the server the most recent parameters at end.
It updates parameter current to refer to, replaces parameter current using most recent parameters.After completing replacement, parameter current cancels,
Using most recent parameters as parameter current.
Parameter current is identical as the project of the included data of most recent parameters.Parameter current also include: battery ageing parameter,
Internal resistance, capacity, temperature-compensating, voltage and electricity the data such as corresponding relationship.
Although specifically, parameter current is identical as the project of the included data of most recent parameters, unlike, when
Preceding parameter is: in terminal system locating for battery, battery parameter currently in use；Most recent parameters are: according to the work shape of battery
State, the battery parameter of newest acquisition.
With the growth of service time of battery, the variation of use environment, battery parameter can also change, for example, battery
Will use the growth of time, Degree of Ageing increases, so, the value of data may be different in parameter current and most recent parameters.And
And the phenomenon that there is also other batteries of terminal cross-reference, then in terminal system battery parameter currently in use with
The battery used is unmatched.In this way, parameter current is history battery parameter, it cannot correctly reflect the true of battery
Situation, and most recent parameters are current battery parameters, can correctly reflect the truth of battery.Exactly because also this
The reason of sample, needs to update parameter current with the most recent parameters of battery.
Such as: referring to the schematic diagram of the management method of battery parameter according to an embodiment of the invention shown in Fig. 2.First
Terminal built-in first battery when dispatching from the factory, first terminal use the parameter current of the first battery, also, according to the current of the first battery
Parameter adjusts the working condition of itself.Such as, first terminal is according to current temperature, in conjunction with currently in use in first terminal system
Parameter current adjusts the working condition of processor.But first terminal can be with other end cells of cross-reference, such as first eventually
End and second terminal cross-reference battery, and parameter current currently in use may not in the battery parameter of the second battery and system
Together.In this way, when that is to say that the second battery is started to work in first terminal, being read by first terminal when the second battery is reworked
The ID of the second battery is taken, such as 002, the corresponding most recent parameters of the ID:002 are obtained from server end, and replace using the most recent parameters
Change the parameter current of the first battery currently in use in first terminal, first terminal according to the adjustment of the most recent parameters of the second battery from
The working condition of body.
