Specific embodiment

Schema is refer to, wherein identical element numbers represent identical component, and principle of the invention is to implement one Illustrated in appropriate computing environment.The following description is that, based on the illustrated specific embodiment of the invention, it should not be by It is considered as the limitation present invention other specific embodiments not detailed herein.

Will be detailed below.

Fig. 1 is referred to, Fig. 1 is the schematic flow sheet of the update method of battery capacity value provided in an embodiment of the present invention, flowed Journey can include：

In step S101, the working condition to terminal is detected.

It is understood that the executive agent of the embodiment of the present invention can be the terminal devices such as smart mobile phone, panel computer.

Such as, many terminal devices are all come the residual electric quantity of computing terminal battery by voltameter on the market.This The mode of kind needs to obtain the several parameter values of end cell, including the rated capacity value of battery.Then, then by these parameters Value substitutes into the residual electric quantity that certain computing formula is calculated battery.However, actually the capability value of battery can be subject to very Multifactor influence, such as temperature and battery itself it is aging etc..Therefore, the rated capacity value according to battery is calculated Dump energy the degree of accuracy it is relatively low.

The step of the embodiment of the present invention in S101, the working condition that terminal can be first to itself is detected.

It should be noted that the working condition of terminal can include such as open state, off-mode, charged state, normal Discharge condition (uncharged) when using, etc., illustrates and does not constitute limitation of the invention herein.

In step s 102, when terminal is detected into the working condition of mark in advance, corresponding battery parameter is obtained Value and preset battery capacity calculation expression.

Such as, when terminal detects itself enters the working condition of mark in advance, can obtain pre- with this with triggering terminal The working condition that first marks corresponding battery parameter value and preset battery capacity calculation expression.That is, working as terminal When entering into the working condition of different advance marks, terminal needs to obtain the parameter value of different parameters and different default Battery capacity calculation expression formula.

It should be noted that terminal can be marked to a few thing state in advance, the work of advance mark is made Make state.For example, the working condition of mark can be including open state and charged state etc. in advance.

In a kind of possible implementation method, terminal can previously generate a default mapping table, the default correspondence Relation table record each advance mark working condition and its correspondence the need for obtain parameter item and preset battery capacity calculate Expression formula.

For example, default mapping table can include the content in table 1：

Table 1：The working condition for marking in advance and parameter value and battery capacity calculation expression formula mapping table

Based on this, such as when it is the open state by advance mark that terminal detects its working condition, can trigger Terminal obtains the current temperature value of battery corresponding with open state, and preset function expression formula according to table 1.When terminal detection When to its working condition being the charged state by advance mark, can obtain corresponding with charged state according to table 1 with triggering terminal Residual electric quantity of battery when starting to charge up, electricity full of when be filled with the quantity of electric charge and default mathematic(al) representation of battery, etc. Deng.

In a kind of possible implementation method, step S102 can include：

When terminal is detected into the working condition of mark in advance, whether detection is in preset time range to terminal Battery capacity value be updated；

If detecting, the battery capacity value not to terminal in preset time range is updated, and obtains corresponding battery Parameter value and preset battery capacity calculation expression.

Such as, when the working condition that the working condition that terminal detects itself is advance mark, terminal can also be examined first Survey whether it carried out renewal in preset time range to battery capacity value.For example, the preset time range can be In nearest 6 hours of current time.

If detecting that battery capacity value of the terminal not to terminal in preset time range carried out renewal, then can The battery parameter value and preset battery capacity computational chart corresponding with the working condition of the advance mark is obtained with triggering terminal Up to formula.

If detecting that battery capacity value of the terminal to terminal in default time range carried out renewal, then Terminal can not be updated temporarily to battery capacity value.For example, terminal detects user for end cell charges at the T1 moment. At this point it is possible to whether triggering terminal detects in its 6 hour before the T1 moment carried out renewal to battery capacity value.Example Such as, terminal detected it before the T1 moment T0 moment of 3 hours carried out renewal to battery capacity value.In such case Under, terminal temporarily no longer can be updated to battery capacity value, namely terminal no longer needs to obtain in this charging process Residual electric quantity, electricity when battery is started to charge up full of when be filled with the quantity of electric charge of battery, it is and corresponding with charged state pre- If mathematic(al) representation, and according to the residual electric quantity, the quantity of electric charge, the default mathematic(al) representation is calculated, obtain corresponding Output valve.

It is understood that when terminal is detected into the working condition of mark in advance, further detection terminal is pre- If whether carried out renewal in time range to battery capacity value, and only to detect terminal not right in preset time range In the case that battery capacity value update, ability triggering terminal performs the step of being updated to battery capacity value.Namely Say, in the case where the renewal that terminal had carried out battery capacity value in preset time range is detected, terminal can take This disappear the step of be updated to battery capacity value, so as to reduce the number of times being updated to battery capacity value.By this Mode can reduce the occupancy to the computing resource of terminal, mitigate terminal burden.

In step s 103, according to the battery parameter value, the preset battery capacity calculation expression is calculated, is obtained Corresponding output valve.

Such as, the corresponding parameter value of the working condition that gets the advance mark being presently in it in terminal and default After battery capacity calculation expression formula, terminal can be calculated preset battery capacity calculation expression according to the parameter value, Obtain corresponding output valve.

For example, after battery current temperature value corresponding with open state and preset function expression formula is got, eventually End can calculate the dependent variable of the preset function expression formula, and the preset function expression formula is with the current temperature value as independent variable.Meter The dependent variable for obtaining is corresponding output valve.

In step S104, battery capacity value is updated according to the output valve, and according to the battery capacity after renewal Value calculates the dump energy of battery.

Such as, calculated to preset battery capacity calculation expression, and after obtaining corresponding output valve, terminal can Battery capacity value is updated with according to the output valve, and after this according to the battery capacity value after renewal go calculate battery Dump energy.

For example, after the dependent variable of the preset function expression formula with battery current temperature value as independent variable is calculated, Terminal can be updated according to the dependent variable to battery capacity value.After being updated to battery capacity value, terminal just can be with The dump energy of battery is calculated using the battery capacity value after renewal.

It is understood that due to being, when terminal is in the working condition of mark in advance, battery capacity value to be carried out more Newly, the battery capacity value and after updating is more nearly the actual capacity value of battery, therefore according to the battery capacity value after the renewal The residual electric quantity being calculated can also be more nearly the real surplus electricity of battery, so the embodiment of the present invention can be improved end End calculates the degree of accuracy of the dump energy of battery.

From the foregoing, the update method of the battery capacity value that the present embodiment is provided, first by the work of terminal-pair itself State is detected.When the working condition that the working condition for detecting terminal is advance mark, can with triggering terminal obtain with The working condition of the advance mark corresponding battery parameter value and preset battery capacity calculation expression.Then, terminal can According to the battery parameter value, to calculate the preset battery capacity calculation expression, and obtain corresponding output valve.It Afterwards, terminal can be updated according to the output valve to battery capacity value, and calculate electricity according to the battery capacity value after renewal The residual electric quantity in pond.Due to being, when terminal is in the working condition of mark in advance, battery capacity value to be updated, and more Battery capacity value after new is more nearly the actual capacity value of battery, therefore is calculated according to the battery capacity value after the renewal Residual electric quantity can also be more nearly the real surplus electricity of battery, the i.e. embodiment of the present invention and can improve terminal and calculate battery Dump energy the degree of accuracy.

Fig. 2 is referred to, Fig. 2 is that another flow of the update method of battery capacity value provided in an embodiment of the present invention is illustrated Figure, flow can include：

In step s 201, terminal-pair working condition is detected.

In step S202, when the working condition for detecting terminal is open state, terminal obtains the current temperature of battery Angle value.

Such as, in a kind of possible implementation method, can also comprise the following steps before step S201：

Obtain multiple battery temperature value samples, and battery capacity value sample corresponding with each battery temperature value sample；

According to battery temperature value sample, temperature range is generated, each temperature range includes temperature upper limit and temperature upper limit value；

According to battery capacity value sample, obtain battery capacity value corresponding with each temperature upper limit and with each temperature The corresponding battery capacity value of limit value；

Temperature upper limit, temperature upper limit value battery capacity value corresponding with temperature upper limit according to each temperature range, Battery capacity value corresponding with temperature upper limit value, generates corresponding with each temperature range function expression, and by the function table It is defined as preset function expression formula up to formula.

Such as, terminal can obtain 4 battery temperature value samples, and electricity corresponding with this 4 battery temperature value samples Tankage value sample.For example, 4 battery temperature value samples that terminal gets are respectively -10 DEG C, 0 DEG C, 25 DEG C, 50 DEG C, and with This corresponding battery capacity value sample of 4 temperature value samples is respectively 2500mAh, 2700mAh, 3000mAh, 2600mAh.

In a kind of possible implementation method, can in the following way obtain corresponding with each battery temperature value sample Battery capacity value sample：In laboratory environments, control battery temperature is maintained at a set temperature value, and in the set temperature value It is under environment, battery is fully charged.Then, battery is discharged according to the size of current of setting, until battery stops discharging, note The electric discharge duration of battery during recording this.Then discharge current value is multiplied with electric discharge duration, is calculated the capability value of battery.

For example, control battery temperature is maintained at 25 DEG C, and it is under the temperature environment that battery is fully charged.Afterwards, equally exist Discharged with the current versus cell of 500mA sizes under the temperature environment, when battery discharge is finished, and recorded battery discharge A length of 6 hours, then discharge current value 500mA is mutually obtained into battery capacity value 3000mAh in 6 hours at convenience with electric discharge duration.Need It is noted that there is the control circuit for self-protection in battery, in battery discharge procedure, when the electricity for detecting battery Pressure is when being reduced to discharge cut-off voltage, and battery can stop electric discharge, but now in battery also has sub-fraction electricity.Due to this portion Divide electricity very little and be not involved in battery discharge, therefore this part electricity can be ignored when battery capacity value is calculated.

Counting on these battery temperature value samples, and battery capacity value sample corresponding with each battery temperature value sample Afterwards, these sample values can be stored in the default file of terminal and be called for terminal.

After multiple battery temperature value samples and corresponding battery capacity value sample are got, terminal can first according to this A little battery temperature value samples, generate temperature range, and each temperature range of generation all includes temperature upper limit and temperature upper limit value.

For example, terminal is according to 4-10 DEG C of the battery temperature value samples for getting, 0 DEG C, 25 DEG C, 50 DEG C, the temperature of generation Interval is [- 10,0], [0,25] and [25,50].

After temperature range is generated, terminal can according to the battery capacity value sample for getting before, obtain with it is each The corresponding battery capacity value of temperature upper limit of temperature range, and battery capacity value corresponding with temperature upper limit value.For example, right It is 2700mAh with 0 DEG C of corresponding battery capacity value of temperature upper limit value, with temperature upper limit 25 for temperature range [0,25] DEG C corresponding battery capacity value is 3000mAh.

Then, terminal can be corresponding with temperature upper limit according to the temperature upper limit of each temperature range, temperature upper limit value Battery capacity value battery capacity value corresponding with temperature upper limit value, generate corresponding with each temperature range function expression, And the function expression is defined as corresponding preset function expression formula.

In a kind of possible implementation method, the function expression corresponding with each temperature range of generation can be a letter Number expression formula.For example, for for temperature range [0,25], with (0,2700) and (25,3000) as corresponding linear function 2 points on the rectilinear picture of expression formula, then by the linear function expression formula that is calculated be y=12x+2700.Similarly, For temperature range [- 10,0], the corresponding linear function expression formula of generation is y=20x+2700.For temperature range [25, 50], the corresponding linear function expression formula of generation is y=-16x+3400.

After function expression corresponding with each temperature range is generated, can be defined as the function expression by terminal Preset function expression formula corresponding with each temperature range.For example, terminal can generate a mapping table, such as table 2：

Table 2：Temperature range and preset function expression formula mapping table

Temperature range	Corresponding preset function expression formula
		[-10,0]	Y=20x+2700
[0,25]	Y=12x+2700
		[25,50]	Y=-16x+3400

In terminal in actual use, such as step S201 and S202 can include：

Terminal can be detected to the working condition of itself, when the working condition for detecting terminal is open state, The current temperature value of its battery can be obtained with triggering terminal.

In step S203, terminal obtains corresponding preset function expression formula according to the current temperature value.

Such as, after the current temperature value for getting its battery, terminal can obtain correspondence according to the current temperature value Preset function expression formula.

In a kind of possible implementation method, terminal can first determine the current temperature according to the current temperature value of battery Temperature range belonging to angle value, then obtains preset function expression formula corresponding with the temperature range again.

For example, in step S202, the current temperature value of the battery that terminal gets is 22 DEG C.Terminal determines that this is current Temperature value belongs to [0,25] this temperature range, and then terminal with inquiry table 2, and can obtain corresponding with the temperature range default Function expression y=12x+2700.

In step S204, terminal calculates the dependent variable of the preset function expression formula, the preset function expression formula with deserve Preceding temperature value is independent variable.

Such as, after the preset function expression formula corresponding with battery current temperature value is got, terminal can be calculated The dependent variable of the preset function expression formula, the preset function expression formula is with the current temperature value as independent variable.

For example, after preset function expression formula y=12x+2700 is got, terminal can use 22 DEG C of current temperature value Numerical value is calculated preset function expression formula y=12x+2700 for independent variable, and the dependent variable for obtaining is 2964.

In step S205, terminal is updated according to the dependent variable to battery capacity value, and according to the electricity after renewal Tankage value calculates the dump energy of battery.

Such as, after the dependent variable of preset function expression formula is calculated, terminal can be according to the dependent variable to battery Capability value is updated, and the dump energy of battery is calculated according to the battery capacity value after renewal.

For example, after dependent variable 2964 is calculated, terminal can replace original battery with the dependent variable 2964 Capability value.Also, before updated to battery capacity value next time, control terminal is according to the battery capacity value after renewal 2964mAh calculates the dump energy of battery.

It is understood that needing during due to starting up of terminal to calculate the dump energy of battery, therefore the elder generation in starting up of terminal Battery capacity value is updated according to battery temperature value, the battery capacity value after renewal is more nearly actual capacity value, that The battery dump energy being calculated according to the battery capacity value after renewal can also be closer to real surplus electricity, that is, lead to Crossing this mode can improve the degree of accuracy that terminal calculates dump energy.

Fig. 3 is referred to, Fig. 3 is the schematic diagram of a scenario of the update method of battery capacity value provided in an embodiment of the present invention.

For example, terminal is in off-mode originally, user picks up terminal afterwards, and the terminal supplying power key with thumb-activated, Operation is booted up to terminal, now terminal can be detected and itself enter open state.

When the working condition for detecting terminal is open state, the current temperature value of battery can be obtained with triggering terminal. For example, the current temperature value of battery that terminal gets is 22 DEG C.Then, terminal can read default mapping table (i.e. table 2), and determine that 22 DEG C of current temperature value belongs to default temperature range [0,25].Afterwards, terminal can inquire about the preset relation Table, and obtain and the corresponding function expression y=12x+2700 of temperature range [0,25].

After function expression y=12x+2700 is got, terminal can be with the numerical value 22 of 22 DEG C of current temperature value Independent variable is calculated preset function expression formula y=12x+2700, and the dependent variable for obtaining is 2964.

After dependent variable 2964 is calculated, terminal can replace original battery capacity with the dependent variable 2964 Value, also will battery capacity value be updated to 2964mAh.Also, before updated to battery capacity value next time, control is eventually End calculates the dump energy of battery according to the battery capacity value 2964mAh after renewal.

Fig. 4 is referred to, Fig. 4 is that the another flow of the update method of battery capacity value provided in an embodiment of the present invention is illustrated Figure, flow can include：

In step S301, terminal-pair working condition is detected.

In step s 302, when the working condition for detecting terminal is charged state, terminal obtains electricity when starting to charge up The residual electric quantity in pond, and electricity full of when be filled with the quantity of electric charge of battery.

Such as, step S301 and S302 can include：

The working condition of terminal-pair itself is detected.It is the working condition of terminal charge, i.e. terminal when user is detected During for charged state, the residual electric quantity of battery when it is started to charge up can be obtained with triggering terminal, and electricity full of when be filled with The quantity of electric charge (being filled with the coulomb amount of battery) of battery.

For example, when the working condition for detecting terminal is charged state, battery when starting to charge up that terminal gets Residual electric quantity is the 50% of battery total electricity.Through after a period of time, the electricity that terminal detects battery has been filled with, now eventually End can stop charging.Now, the quantity of electric charge for being filled with battery is obtained by terminal.For example, the electricity that terminal is read by voltameter Full of when be filled with battery the quantity of electric charge be 1480mAh.

In step S303, terminal obtains default mathematic(al) representation corresponding with charged state.

In step s 304, terminal is counted according to the residual electric quantity and the quantity of electric charge to the default mathematic(al) representation Calculate, obtain corresponding output valve.

Such as, step S303 and S304 can include：

Getting residual electric quantity when battery is started to charge up, and electricity full of when be filled with battery the quantity of electric charge it Afterwards, default mathematic(al) representation corresponding with charged state can be obtained with triggering terminal.The default mathematic(al) representation is for calculating The expression formula of battery capacity value.

In a kind of possible implementation method, default mathematic(al) representation can be fcc=cc/ (100%-d0).This is preset Fcc represents battery capacity value in mathematic(al) representation, cc represent electricity full of when be filled with the quantity of electric charge of battery, d0 represents that battery starts Dump energy percentage during charging, namely dump energy accounts for the percentage of total electricity.

It should be noted that above-mentioned default mathematic(al) representation is according to terminal system electricity calculation expression soc=d0+ (cc/fcc) * 100% obtain.Soc represents system spare electricity percentage in the system charge calculation expression, and d0 is represented System initial quantity of electricity percentage, cc represents the electricity that system increases or consumes, and cc is on the occasion of cc is upon discharging when charging Negative value, fcc represents battery capacity value.When electricity is full of, soc is defaulted as 100%.

After default mathematic(al) representation is got, when terminal can be started to charge up according to the battery obtained in step S302 Residual electric quantity (dump energy percentage) and electricity full of when be filled with the quantity of electric charge of battery, to the default mathematic(al) representation Calculated, obtained corresponding output valve.

For example, in step s 302, dump energy percentage when starting to charge up that terminal gets is 50%, and electricity fills The quantity of electric charge that battery is filled with when full is 1480mAh, then default mathematic(al) representation is carried out being calculated fcc=according to both 1480mAh/ (100%-50%)=2960mAh.

In step S305, terminal is updated according to the output valve to battery capacity value, and according to the battery after renewal Capability value calculates the dump energy of battery.

Such as, calculated to default mathematic(al) representation, after obtaining the output valve of the default mathematic(al) representation, terminal Battery capacity value can be updated according to the output valve, and control terminal calculates electricity according to the battery capacity value after renewal The dump energy in pond.

For example, the battery capacity value fcc that the default mathematic(al) representation of terminal-pair is calculated is 2960mAh, then eventually End can replace the original battery capacity value of terminal with 2960mAh.Also, it is being updated next time to battery capacity value Before, control terminal calculates the dump energy of battery according to the battery capacity value 2960mAh after renewal.

It is understood that because when electricity is full of, battery can be automatically stopped charging, to prevent overcharge.Therefore, it can The electricity percentage of battery is defaulted as 100% when electricity is full of, and the dump energy hundred of battery when starting to charge up is subtracted with 100% Point ratio, resulting is exactly that the quantity of electric charge for being filled with battery accounts for the percentage of battery capacity value, and the quantity of electric charge for being filled with battery can be with Arrived by voltameter accurate statistics, therefore electricity is also more nearly according to the battery capacity value that the quantity of electric charge for being filled with battery is calculated The actual capacity value in pond.So, reality is also more closely corresponded to according to the dump energy that the battery capacity value after renewal is calculated Border dump energy, i.e., can improve the degree of accuracy for calculating battery dump energy in this way.

Fig. 5 is referred to, Fig. 5 is that another scene of the update method of battery capacity value provided in an embodiment of the present invention is illustrated Figure.

Such as, user is charged for terminal has accessed charging wire, and now terminal will detect that the working condition of itself is Charged state.In such a case, it is possible to residual electric quantity and electricity that triggering terminal obtains battery when starting to charge up are full of When be filled with the quantity of electric charge (i.e. coulomb amount) of battery.

For example, when the working condition for detecting terminal is charged state, battery when starting to charge up that terminal gets Residual electric quantity is the 50% of battery total electricity.Through after a period of time, the electricity that terminal detects battery has been filled with, now eventually End can stop charging.Now, the electricity that terminal is read by voltameter full of when to be filled with the quantity of electric charge of battery be 1490mAh.

Get start to charge up when battery dump energy percentage 50%, and electricity full of when be filled with the electricity of battery After lotus amount 1490mAh, terminal can obtain default mathematic(al) representation corresponding with charged state, and the default mathematic(al) representation is Expression formula for calculating battery capacity value.In a kind of possible implementation method, default mathematic(al) representation can be fcc= Cc/ (100%-d0).Fcc represents battery capacity value in the default mathematic(al) representation, cc represent electricity full of when be filled with battery The quantity of electric charge, dump energy percentage when d0 represents that battery is started to charge up, namely dump energy accounts for the percentage of total electricity.

For example, by d0=50%, cc=1480mAh substitutes into above-mentioned default mathematic(al) representation fcc=cc/ (100%-d0), Fcc=2960mAh can be calculated.

After the output valve 2960mAh of default mathematic(al) representation fcc=cc/ (100%-d0) is calculated, terminal The original battery capacity value of terminal can be replaced with 2960mAh.Also, before updated to battery capacity value next time, Control terminal calculates the dump energy of battery according to the battery capacity value 2960mAh after renewal.

It should be noted that in the embodiment of the present invention, whenever terminal detects the open state for itself entering mark in advance Or during charged state, it is possible to triggering terminal performs the step of being updated to battery capacity value accordingly.Or, terminal is in inspection When the working condition for measuring itself is the working condition of advance mark, can first detect whether entered in preset time range Went the renewal of battery capacity value.If detecting the renewal that battery capacity value was not carried out in preset time range, then can The step of being updated to battery capacity value accordingly is performed with triggering terminal.If detecting to have entered in preset time range Went the renewal of battery capacity value, then terminal can not perform first it is corresponding the step of being updated to battery capacity value, and The renewal opportunity being to wait for next time arrives.

The embodiment of the present invention also provides a kind of renewal of the battery capacity value of the update method based on above-mentioned battery capacity value Device.Wherein the implication of noun is identical with the update method of above-mentioned battery capacity value, implements details and may be referred to method Explanation in embodiment.

Fig. 6 is referred to, Fig. 6 is the structural representation of the updating device of battery capacity value provided in an embodiment of the present invention.Electricity The updating device 300 of tankage value can include：Detection module 301, acquisition module 302, computing module 303, and update mould Block 304.

Detection module 301, detects for the working condition to terminal.

Such as, the working condition that the detection module 301 of terminal can be first to itself is detected.

Acquisition module 302, for when terminal is detected into the working condition of mark in advance, obtaining corresponding battery ginseng Numerical value and preset battery capacity calculation expression.

Such as, during detection module 301 is detected to the working condition of terminal, if detection module 301 is detected Enter the working condition of mark in advance to terminal, then can be obtained and the advance mark with the acquisition module 302 of triggering terminal The corresponding battery parameter value of working condition and preset battery capacity calculation expression.That is, when terminal is entered into not With advance mark working condition when, acquisition module 302 needs to obtain the parameter value of different parameters and different default Battery capacity calculation expression formula.

For example, default mapping table can include the content in table 1：

Based on this, such as when the working condition that detection module 301 detects terminal is the open state by advance mark When, the current temperature value that acquisition module 302 obtains battery corresponding with open state according to table 1, and default letter can be triggered Number expression formula.When it is the charged state by advance mark that detection module 301 detects its working condition, acquisition can be triggered Module 302 obtained according to table 1 residual electric quantity when corresponding with charged state battery is started to charge up, electricity full of when be filled with electricity The quantity of electric charge in pond and default mathematic(al) representation, etc..

In a kind of possible implementation method, acquisition module 302 can be used for：

Such as, when the working condition that the working condition that detection module 301 detects itself is advance mark, acquisition module 302 can also first detect whether it carried out renewal in preset time range to battery capacity value.For example, when this is default Between scope can be in nearest 6 hours of current time.

If detecting that battery capacity value of the terminal not to terminal in preset time range carried out renewal, then can Battery parameter value and the preset battery capacity corresponding with the working condition of the advance mark is obtained to trigger acquisition module 302 Calculation expression.

If detecting that battery capacity value of the terminal to terminal in default time range carried out renewal, then Terminal can not be updated temporarily to battery capacity value.For example, it is terminal electricity that detection module 301 detects user at the T1 moment Charge in pond.At this point it is possible to whether trigger in its 6 hour before the T1 moment of the detection of acquisition module 302 to battery capacity Value carried out renewal.For example, acquisition module 302 detected it before T1 moment T0 moment of 3 hours is to battery capacity Value carried out renewal.In this case, terminal temporarily no longer can be updated to battery capacity value, namely in this charging During terminal no longer need to obtain residual electric quantity of battery when starting to charge up, electricity full of when be filled with the quantity of electric charge of battery, And default mathematic(al) representation corresponding with charged state, and according to the residual electric quantity, the quantity of electric charge, to the default mathematical expression Formula is calculated, and obtains corresponding output valve.

Computing module 303, for according to the battery parameter value, being counted to the preset battery capacity calculation expression Calculate, obtain corresponding output valve.

Such as, the corresponding parameter of the working condition that gets the advance mark being presently in terminal in acquisition module 302 After value and preset battery capacity calculation expression, computing module 303 can be according to the parameter value, to preset battery capacity meter Operator expression formula is calculated, and obtains corresponding output valve.

For example, getting battery current temperature value corresponding with open state and preset function table in acquisition module 302 Up to after formula, computing module 303 can calculate the dependent variable of the preset function expression formula, and the preset function expression formula is current with this Temperature value is independent variable.The dependent variable being calculated is corresponding output valve.

Update module 304, for being updated to battery capacity value according to the output valve, and according to the battery after renewal Capability value calculates the dump energy of battery.

Such as, preset battery capacity calculation expression is calculated in computing module 303, and obtains corresponding output valve Afterwards, the update module 304 of terminal can be updated according to the output valve to battery capacity value, and after this according to renewal Battery capacity value afterwards goes to calculate the dump energy of battery.

For example, being calculated the preset function expression formula with battery current temperature value as independent variable in computing module 303 After dependent variable, update module 304 can be updated according to the dependent variable to battery capacity value.Carried out to battery capacity value After renewal, terminal can just calculate the dump energy of battery using the battery capacity value after updating.

For example, in a kind of possible implementation method, the acquisition module 302 of terminal can be used for：

When the working condition for detecting terminal is charged state, the residual electric quantity of battery when acquisition is started to charge up, with And electricity full of when be filled with the quantity of electric charge of battery；

Obtain default mathematic(al) representation corresponding with charged state.

Based on this, computing module 303 can be used for：According to the residual electric quantity and the quantity of electric charge, to described pre- If mathematic(al) representation is calculated, corresponding output valve is obtained.

For example, when the working condition that detection module 301 detects terminal is charged state, acquisition module can be triggered The residual electric quantities of 302 acquisition terminals batteries when starting to charge up, and electricity full of when be filled with the quantity of electric charge (the i.e. coulomb of battery Amount).

For example, the residual electric quantity of battery when starting to charge up that acquisition module 302 gets is the 50% of battery total electricity. Through after a period of time, the electricity that terminal detects battery has been filled with, now terminal can stop charging.Now, terminal is by electricity The electricity that gauge reads full of when be filled with battery the quantity of electric charge be 1490mAh.

Get residual electric quantity when battery is started to charge up in acquisition module 302, and electricity full of when be filled with battery The quantity of electric charge after, acquisition module 302 can be triggered and obtain default mathematic(al) representation corresponding with charged state again.The present count It is the expression formula for calculating battery capacity value to learn expression formula.

After default mathematic(al) representation is got, the battery that computing module 303 can be obtained according to acquisition module 302 is opened Residual electric quantity (dump energy percentage) and electricity when beginning to charge full of when be filled with the quantity of electric charge of battery, to the present count Learn expression formula to be calculated, obtain corresponding output valve.

For example, dump energy percentage when starting to charge up that gets of acquisition module 302 is 50%, electricity full of when fill The quantity of electric charge for entering battery is 1490mAh, then default mathematic(al) representation is carried out being calculated fcc=according to both 1480mAh/ (100%-50%)=2960mAh.

Calculated to default mathematic(al) representation, after obtaining the output valve of the default mathematic(al) representation, update module 304 can be updated according to the output valve to battery capacity value, and control terminal is counted according to the battery capacity value after renewal Calculate the dump energy of battery.

For example, the battery capacity value fcc that 303 pairs of default mathematic(al) representations of computing module are calculated is 2960mAh, So update module 304 can replace the original battery capacity value of terminal with 2960mAh.Also, carried out to battery capacity value Update next time before, control terminal calculates the dump energy of battery according to the battery capacity value 2960mAh after renewal.

Also referring to Fig. 7, Fig. 7 is that another structure of the updating device of battery capacity value provided in an embodiment of the present invention is shown It is intended to.In one embodiment, the updating device 300 of battery capacity value can also include：Generation module 305.
