Example two

Referring to fig. 2, fig. 2 is a flowchart illustrating another method for determining a remaining service life of a battery according to an embodiment of the invention. The method described in fig. 2 may be applied to a determining device, where the determining device is used to determine a remaining usage time (i.e., a duration) of a battery used by a device, and the determining device may exist independently of the device, or may be installed or integrated in the device, where the embodiment of the invention is not limited, further, the device may be a lighting device, in some application scenarios, a plurality of types of batteries may be connected to the lighting device, or a control box connected to the lighting device may be connected to a plurality of types of batteries, and of course, the device may also be a charging box of the lighting device, a charging battery box, a recording device, a shooting device, a mobile terminal (for example, a mobile phone, a tablet, etc., where the embodiment of the invention is not limited. Further, the battery used by the device may be a battery of the device itself or an external battery used by the device, and it should be specifically noted that the external battery is relative to the battery of the device itself, and is not limited to a positional relationship, a connection manner, and the like of the device and the external battery, and the external battery may be externally hung on the device, or may be packaged or connected in a housing of the device, so as to realize power supply to the device. It should be noted that the method described in fig. 2 is applicable to a scenario in which the battery type of the battery used by the device cannot be directly determined. As shown in fig. 2, the remaining use time length determining method of the battery may include the operations of:

201. After the target device is powered on, the determining means determines the default battery type as the target battery type of the target battery currently used by the target device.

In the embodiment of the present invention, the determination manner of the target battery type described in step 201 is a default determination manner. The default battery type may be a specific battery type, or may be one selected from a plurality of battery types.

202. The determining means matches the remaining use time length calculation means corresponding to the determination means of the target battery type according to the determination means of the target battery type.

In the embodiment of the present invention, the remaining usage time length calculation mode corresponding to the determination mode of the target battery type is a remaining usage time length calculation mode corresponding to the default determination mode, specifically, a first time length calculation formula corresponding to the default determination mode, where the first time length calculation formula is used to calculate an initial remaining usage time length of the target battery.

203. The determination device acquires a current battery voltage and a current output power of the target battery.

204. The determining means screens the matching output power of the present output power from the predetermined plurality of output powers, and screens the matching battery voltage of the present battery voltage from the predetermined plurality of battery voltages.

The selected matching output power of the current output power may be the matching output power which is equal to the current output power and is selected from a plurality of predetermined output powers or the matching output power which has a difference value smaller than or equal to a preset power threshold value with the current output power, or may be the maximum output power smaller than the current output power and the minimum output power larger than the current output power in the plurality of predetermined output powers. The selected matching battery voltage of the current battery voltage may be the matching battery voltage which is equal to the current battery voltage or the matching battery voltage which is smaller than or equal to a preset voltage threshold value and is selected from a plurality of battery voltages, or may be the maximum battery voltage which is smaller than the current battery voltage and the minimum battery voltage which is larger than the current battery voltage among the plurality of battery voltages which are determined in advance.

205. The determining device calculates initial remaining use duration of the target battery under the current output power and the current battery voltage according to the queried fixed remaining use duration, the current output power, the matched output power and a first time duration calculation formula.

The fixed remaining use duration is the queried remaining use duration of the battery of the target battery type under the conditions of matching output power and matching battery voltage.

When the matching output power is a matching output power equal to the current output power or a matching output power having a difference from the current output power equal to or smaller than a preset power threshold value, which is selected from a plurality of predetermined output powers, and the matching battery voltage is a matching battery voltage equal to or smaller than a preset voltage threshold value, which is selected from a plurality of battery voltages, the determining means may directly determine the queried fixed remaining use time period as the initial remaining use time period of the target battery.

In an embodiment of the present invention, as an optional implementation manner, the determining device filters the matched output power of the current output power from a plurality of predetermined output powers, which may include:

the determining means screens, from among the plurality of output powers determined in advance, the maximum output power smaller than the current output power as a first matching output power of the current output power, and screens the minimum output power larger than the current output power as a second matching output power of the current output power.

In this alternative embodiment, the first time length calculation formula is:

T _d ＝T ₂ +(T ₁ -T ₂ )*(P _d -P ₁ )/(P ₂ -P ₁ )；

wherein T is _d To calculate the initial remaining use time of the target battery, P _d For the current output power, T ₁ For a first fixed remaining use period, T, of the queried battery of the target battery type at a first matched output power and matched battery voltage ₂ For a second fixed remaining use period, P, of the queried battery of the target battery type at a second matched output power and matched battery voltage ₁ For the first matched output power, P ₂ And outputting power for the second match.

In this alternative embodiment, the determining means may directly query the required fixed remaining usage time period from the pre-generated remaining usage time period data corresponding to the batteries of different battery types at different battery voltages and different output powers. The remaining usage time length data corresponding to the batteries of different battery types under different battery voltages and different output powers may be generated in advance by the determining device or may be generated in advance by other devices or apparatuses, which is not limited in the embodiment of the present invention.

It should be further noted that, when the matched battery voltage includes a predetermined maximum battery voltage (i.e., a first matched battery voltage) less than the current battery voltage and a predetermined minimum battery voltage (i.e., a second matched battery voltage) greater than the current battery voltage, the determining device may query two sets of first fixed remaining usage periods and second fixed remaining usage periods, and the determining device may calculate the first initial remaining usage period and the second initial remaining usage period of the target battery by combining the first time period calculation formula and each set of first fixed remaining usage period and second fixed remaining usage period respectively. After that, the determination means can finally calculate the initial remaining use time length of the target battery by:

The determining device takes the average value of the first initial remaining use duration and the second initial remaining use duration as the final calculated initial remaining use duration of the target battery; or,

the determining device respectively determines a first weight value corresponding to the first matched battery voltage and a second weight value corresponding to the second matched battery voltage, and calculates the product of the first weight value and the first initial residual use duration and the product of the second weight value and the second initial residual use duration;

the determining means calculates the sum of the product of the first weight value and the first initial remaining usage period and the product of the second weight value and the second initial remaining usage period as the final calculated initial remaining usage period of the target battery.

Optionally, the weight value corresponding to the matched battery voltage may be determined by matching the voltage difference between the battery voltage and the current battery voltage, where the smaller the battery difference is, the larger the corresponding weight value is, and the larger the voltage difference is, the smaller the corresponding weight value is.

The first fixed residual use duration of the first group is obtained by inquiring the first matched battery voltage, the first matched output power and the target battery type, and the second fixed residual use duration of the first group is obtained by inquiring the first matched battery voltage, the second matched output power and the target battery type; the first fixed remaining use duration of the second group is obtained by inquiring the second matched battery voltage, the first matched output power and the target battery type, and the second fixed remaining use duration of the second group is obtained by inquiring the second matched battery voltage, the second matched output power and the target battery type.

Therefore, under the condition that the battery type of the battery cannot be directly determined, the method can determine the battery type of the battery as the default battery type and calculate the remaining service life of the battery according to the duration calculation formula corresponding to the default battery type, and the method provides a calculation mode of the remaining service life of the battery under the condition that the battery type of the battery cannot be directly determined, and the calculation of the remaining service life only requires the current parameter of the battery, the matched fixed parameter and the queried fixed parameter, thereby being beneficial to improving the calculation efficiency.

In an alternative embodiment, the method may further comprise the operations of:

206. the determining means records a target period of time for which the battery voltage of the target battery is used by the first battery voltage threshold value, which is predetermined by the decrease in the current battery voltage, at the current output power.

In this alternative embodiment, the predetermined first battery voltage threshold may be determined by a predetermined interval voltage value V _gap And the number of intervals N is determined, and the first battery voltage threshold is equal to N _gap For example 6*V _gap . It should be noted that, if the battery voltage value of the current battery voltage drop has not reached the first battery voltage threshold, the recording is continued and the battery voltage drop is waited until the current battery voltage drop reaches the first battery voltage threshold determined in advance, and the target duration may be specifically recorded by the associated timing module.

207. The determining device calculates the theoretical duration used by the first battery voltage threshold value of the current battery voltage drop under the current output power of the battery voltage of each battery type in the plurality of battery types, and obtains the theoretical duration corresponding to each battery type.

It should be noted that, the theoretical duration used by the battery voltage of each battery type of the plurality of battery types to be reduced by the first battery voltage threshold value under the current output power may be calculated by substituting the relevant parameter corresponding to the battery voltage of each battery type to be reduced by the first battery voltage threshold value under the current output power into the first duration calculation formula.

208. The determining device compares the difference value between the theoretical time lengths corresponding to all kinds of battery types and the target time length to obtain the battery type corresponding to the theoretical time length with the smallest difference value, and the battery type is used as the calibration battery type.

209. The determining means calibrates the target battery type of the target battery from the default battery type to a calibrated battery type.

It should be noted that, the current battery voltage may be the initial battery voltage of the target battery.

It can be seen that, in this alternative embodiment, after the initial battery type of the battery is determined by the default determining manner, the determined initial battery type is further calibrated by comparing the recorded actual duration with the calculated difference value of the plurality of theoretical durations, which improves the accuracy of the finally determined battery type and is beneficial to further improving the accuracy of calculating the remaining use duration of the battery according to the accurate battery type.

In another alternative embodiment, after performing the finishing step 209, the method may further include the operations of:

210. when the remaining use time of the target battery at the target battery voltage and the target output power needs to be calculated, the determining device calculates a corresponding remaining use time long calibration value of the target battery.

The target battery voltage may be any battery voltage obtained after each predetermined second battery voltage threshold value is reduced from the initial battery voltage, and the target output power may be the current output power, where the second battery voltage threshold value may be equal to the first battery voltage threshold value.

211. The determining device calculates the actual remaining use duration of the target battery under the target battery voltage and the target output power according to the theoretical remaining use duration calculated by calibrating the battery type, the target battery voltage and the target output power and the corresponding remaining use duration calibration value of the target battery.

In this alternative embodiment, further alternatively, the target battery corresponds to the remaining in-use long calibration value R _type Equal to the ratio of the actual in-use time length t_real at which the battery voltage of the target battery drops by a predetermined second battery voltage threshold value to the target battery voltage at the target output power to the theoretical in-use time length t_type at which the battery voltage of the target battery drops by the second battery voltage threshold value to the target battery voltage at the target output power, that is: long-time remaining-period-of-use calibration value R corresponding to target battery _type ＝T_real/T_type。

In this alternative embodiment, further alternatively, the actual remaining usage period t_real_remaining of the target battery at the target battery voltage and the target output power is equal to the theoretical remaining usage period t_remaining calculated by calibrating the battery type, the target battery voltage, and the target output power and the remaining usage period long calibration value R corresponding to the target battery _type I.e.: t_real_domain=t_domain×r _type 。

It should be noted that, the principle of "calibrating the calculated theoretical remaining use time length according to the remaining use time length calibration value to obtain the actual remaining use time length" described in the above steps 210-211 may also be applied to calculating the actual remaining use time lengths of other batteries of the calibrated battery type or batteries of other battery types, so as to implement continuous calibration of the remaining use time length of the battery, which is beneficial to further improving the accuracy and stability of the calculated remaining use time length of the battery.

It can be seen that, after the battery type of the battery is calibrated, the alternative embodiment can calibrate the calculated theoretical remaining use time length through the calculated remaining use time length calibration value, so as to obtain the actual remaining use time length of the battery, and improve the accuracy and stability of the calculated remaining use time length of the battery after the battery type is calibrated. In addition, the method can also realize the calibration of the remaining use time length of other batteries with the same battery type as the calibration battery type, and is beneficial to further improving the accuracy and stability of the calculated remaining use time length of the battery through continuous calibration.

In yet another alternative embodiment, before the target calculation parameters corresponding to the target device are obtained according to the remaining usage time length calculation mode, and the remaining usage time length of the target battery is calculated according to the target calculation parameters, preferably, before determining the target battery type of the target battery currently used by the target device, the method may further include the operation of:

the determining means determines a plurality of kinds of battery types, a plurality of output powers, a battery voltage range, and an interval voltage value (e.g., V _gap )；

The determining device samples the battery voltage range according to the interval voltage value to obtain a plurality of battery voltages, and the difference value or the absolute value of the difference value of any two adjacent battery voltages is equal to the interval voltage value;

For each battery type, the determining means calculates a length of time that the battery of that battery type is used by each remaining battery voltage to drop to a minimum battery voltage at each output power as a fixed remaining use length of the battery of that battery type at each output power and each remaining battery voltage.

Wherein all remaining battery voltages include all battery voltages except the minimum battery voltage among all battery voltages.

Optionally, for any battery type, the determining means calculates, as the fixed remaining usage period of the battery type at each output power and each remaining battery voltage, a period of time for which the battery of the battery type is used by each remaining battery voltage to drop to the minimum battery voltage, and may include:

the determining means acquires or records the battery voltage of the battery type at each output power every 1V decrease from the initial battery voltage _gap And the used duration is obtained, the corresponding use duration of each battery voltage interval is obtained, and the sum of the corresponding use durations of all battery voltage intervals smaller than each residual battery voltage is calculated and used as the fixed residual use duration of the battery type under each output power and each residual battery voltage.

It can be seen that the optional embodiment can also calculate in advance the fixed remaining usage time length of the battery type under each output power and each remaining battery voltage of the battery of different types, so that the required calculation data can be queried relatively quickly and accurately when the theoretical remaining usage time length or the theoretical time length of the battery is calculated, and the efficiency of the remaining usage time length of the battery of the computing device is improved.

Therefore, under the condition that the battery type of the battery cannot be directly determined, the method can determine the battery type of the battery as the default battery type and calculate the remaining service life of the battery according to the duration calculation formula corresponding to the default battery type, and the method provides a calculation mode of the remaining service life of the battery under the condition that the battery type of the battery cannot be directly determined, and the calculation of the remaining service life only requires the current parameter of the battery, the matched fixed parameter and the queried fixed parameter, thereby being beneficial to improving the calculation efficiency. In addition, after the initial battery type of the battery is determined in a default determination mode, the determined initial battery type is further calibrated by comparing the recorded actual time length with the calculated difference value of a plurality of theoretical time lengths, the accuracy of the finally determined battery type is improved, and the accuracy of calculating the residual use time length of the battery according to the accurate battery type is further improved. In addition, after the battery type of the battery is calibrated, the calculated theoretical remaining use time length is calibrated through the calculated remaining use time length calibration value, so that the actual remaining use time length of the battery is obtained, and the accuracy and stability of the calculated remaining use time length of the battery after the battery type is calibrated are improved. In addition, the method can also realize the calibration of the remaining service time of other batteries with the same battery type as the calibration battery type and the batteries with other battery types, and is beneficial to further improving the accuracy and stability of the calculated remaining service time of the batteries through continuous calibration. In addition, the fixed residual use time of the battery type under each output power and each residual battery voltage of the battery of different types can be calculated in advance, so that the required calculation data can be queried more quickly and accurately when the theoretical residual use time or the theoretical time of the battery is calculated, and the efficiency of the residual use time of the battery of the calculating equipment can be improved. In addition, the calculation and calibration of the remaining use time length of the batteries with different battery types can be realized, and the applicability of the method described by the embodiment of the invention is improved.

For embodiment two, 3 types including the same battery voltage range but different battery capacities are included in the battery typeBattery type, battery voltage in the range of 12V-16.8V (i.e., 12000mV-16800 mV), voltage value V at intervals _gap For 50mV, a plurality of output powers of 60W maximum and 6 output powers at 10W intervals are exemplified as follows:

the 3 battery types include bat_a (maximum capacity), bat_b (center capacity), and bat_c (minimum capacity), respectively;

according to the interval voltage value V _gap The cell voltage range (12000 mV-16800 mV) was sampled to obtain 97 cell voltages, specifically 12000mV, 12050mV, 12100mV, 12150mV, 16750mV, and 16800mV;

the batteries of each battery type need to collect basic data at 6 output powers, and form a time curve based on the basic data collected at each output power, that is: power_1=10w, the corresponding curve is cut_1; power_2=20w, the corresponding curve is curve_2; power_3=30w, the corresponding curve is cut_3; power_4=40w, the corresponding curve is cut_4; power_5=50w, the corresponding curve is cut_5; power_6=60W, and the corresponding curve is cut_6.

The basic data is a data table, and specifically, the time duration that a battery can be used under specific output power and specified battery voltage is one type of battery. For example: the set of base data may be expressed as: base_data [97] = {0,50,150,..10000 }.

Specific: calculating the remaining service time of each type of battery at the specified output power and the specified battery voltage, and recording each drop of the battery voltage from the highest battery voltage by V at the specified output power _gap The duration of time used until the battery voltage drops to a minimum battery voltage shutdown, every drop of V _gap A cell voltage interval is formed and each cell voltage interval is usedThe used time length is recorded, and under the specified output power, the remaining used time length of each battery voltage obtained by sampling is equal to the sum of the used time lengths of all battery voltage intervals lower than the battery voltage, for example, the remaining used time length of the battery voltage of 16800mV is the sum of the used time lengths of all battery voltage intervals; the remaining duration of the cell voltage of 12050mV is the duration of the cell voltage interval 12050mV to 12000 mV. By this procedure, a fixed remaining use period of each type of battery at each output power and each battery voltage can be obtained, wherein the fixed remaining use period of each type of battery at each output power includes a remaining use period of the battery at each battery voltage, for example, 18 sets of remaining use periods are obtained in total for 6 types of output power and 3 types of batteries.

In practical applications, when the device is powered on, the device cannot directly determine the battery type of the battery it uses, so the device defaults to the default battery type for the battery mounted, taking the bat_a type as an example. If the current battery voltage is volt, the current output power is power, and the current output power is between power_4 and power_5, i.e. the duration curve of the current output power is between curve_4 and curve_5. At the current battery voltage volt, the residual use time lengths corresponding to the curve of cut_4 and the curve of cut_5 are t4 and t5, wherein t4> t5 and t4 and t5 are obtained by querying the obtained data table, and at this time, the residual use time length t at the current output power and the current battery voltage volt can be calculated according to a linear formula. The linear calculation formula is as follows: t=t5+ (t 4-t 5)/(power_4)/(power_5-power_4), the device may use the calculated t value as the initial remaining use period of the battery.

After the device has been used for a period of time, the battery voltage of the battery drops by 6V _gap The time period used was t_real, while 3 types (BAT_ A, BAT _B and BAT_C) of batteries were used in this case (6V drops _gap ) The corresponding theoretical time periods are t_ A, t _b and t_c, respectively, wherein t_ A, t _b and t_c are calculated by the linear calculation formula. The device will t_real and pass through the aboveComparing t_ A, t _b and t_c calculated by the linear calculation formula, who is closer to t_real, the battery type of the currently used battery is closer to t_real, for example, t_a is closer to t_real, the current battery type is BAT_A, and the subsequent algorithm calculates the remaining use duration according to the basic data corresponding to BAT_A. This process can be understood as a calibration process for the battery type, and by this process the device can obtain that the actual use time of the battery at this stage is t_real, while the theoretical use time is t_a, the ratio of the actual use time to the theoretical use time is rate, and rate=t_real/t_a. At the battery voltage reduced by 6V _gap The theoretical remaining usage duration of the battery voltage is t_real_domain, and the actual remaining usage duration is t_real_domain, and t_real_domain=t_domain.

After the battery type of the battery is accurately identified, the corresponding algorithm can continuously calibrate the time length so as to ensure that no great deviation exists between the theoretical residual using time length and the actual residual using time length. The specific calibration method is as follows: the device was recently lowered by 6V according to the battery _gap The ratio rate=t_real/t_a of the actual use duration corresponding to the composed battery voltage interval to the theoretical use duration calculated by the above-mentioned linear calculation formula, and the actual remaining use duration t_real_domain is calculated by the ratio and the calculated theoretical remaining use duration of the current battery voltage, where t_real_domain=t_domain. Such as: the current battery voltage is 14000mV, and the values of t_real and t_A are the actual use duration and the calculated theoretical use duration when the battery voltage is reduced from 14300mV to 14000 mV; if the battery voltage drops to the next battery voltage 13950mV, the corresponding battery voltage interval is the battery voltage interval indicated by 14250mV dropping to 13950 mV.

As shown in fig. 4, the remaining use time length determining apparatus of the battery may include:

The obtaining module 401 is configured to obtain a remaining usage time length calculation manner corresponding to the target device, where the remaining usage time length calculation manner is used to calculate a remaining usage time length of a target battery currently used by the target device, and the target device is any device that needs to calculate the remaining usage time length of the battery.

The first calculating module 402 is configured to obtain a target calculation parameter corresponding to the target device according to the remaining usage time duration calculating manner, and calculate a remaining usage time duration of the target battery according to the target calculation parameter.

Therefore, the device described in fig. 4 can calculate the remaining service life of the battery used by the device, so that the user can know the duration of the battery of the device in time, which is beneficial to improving the user experience.

In an alternative embodiment, the specific manner of acquiring the remaining usage time length calculation manner corresponding to the target device by the acquiring module 401 may be:

Therefore, the optional embodiment can also select the matched remaining use time length calculation mode through the determination mode of the battery type in the process of calculating the remaining use time length of the battery so as to calculate the remaining use time length of the battery, and the method is beneficial to improving the flexibility of calculating the remaining use time length of the battery.

In another alternative embodiment, as shown in fig. 5, the apparatus may further include:

a determining module 403, configured to determine a target battery type of a target battery currently used by the target device before the obtaining module 401 obtains a remaining usage time length calculation mode corresponding to the target device.

The specific manner in which the determining module 403 determines the target battery type of the target battery currently used by the target device may be:

after the target device is powered on, determining the default battery type as the target battery type of the target battery currently used by the target device, wherein the determination mode of the target battery type is a default determination mode; or,

after determining the initial battery type of a target battery currently used by the target device, determining a calibration battery type as the target battery type of the target battery, wherein the calibration battery type is obtained after calibrating the initial battery type, and the determination mode of the target battery type is a calibration determination mode; or,

In addition, the method can be suitable for calculating the residual service life of the battery of various battery types, and is beneficial to improving the applicability of the residual service life determining device of the battery.

In yet another alternative embodiment, the determining module 403 is further configured to determine a plurality of types of battery types, a plurality of output powers, a battery voltage range, and an interval voltage value. As shown in fig. 5, the apparatus further includes:

The sampling module 404 is configured to sample the battery voltage range according to the interval voltage value, so as to obtain a plurality of battery voltages, where the difference value or the absolute value of the difference value of any two adjacent battery voltages is equal to the interval voltage value.

As an alternative embodiment, as shown in fig. 6, the first computing module 402 may include:

The first obtaining submodule 4021 is configured to obtain a current battery voltage and a current output power of the target battery when the determination mode of the target battery type is a default determination mode;

Alternatively, the specific manner of screening the matching output power of the current output power from the predetermined multiple output powers by the screening submodule 4022 may be:

from the predetermined plurality of output powers, a maximum output power smaller than the current output power is screened as a first matched output power of the current output power, and a minimum output power larger than the current output power is screened as a second matched output power of the current output power.

And, the first time length calculation formula is:

T _d ＝T ₂ +(T ₁ -T ₂ )*(P _d -P ₁ )/(P ₂ -P ₁ )；

It can be seen that, in this optional embodiment, the battery type of the battery can be determined as the default battery type and the remaining service time of the battery is calculated according to the time length calculation formula corresponding to the default battery type under the condition that the battery type of the battery cannot be directly determined, so that a calculation mode of the remaining service time of the battery under the condition that the battery type of the battery cannot be directly determined is provided, and the remaining service time is calculated only by the current parameter of the battery, the matched fixed parameter and the queried fixed parameter, which is beneficial to improving the calculation efficiency.

The second calculating module 407 is configured to calculate a theoretical duration used by the current battery voltage to drop by the first battery voltage threshold under the current output power for the battery voltage of each battery type in the plurality of battery types, so as to obtain a theoretical duration corresponding to each battery type.

The second calculating module 407 may replace the calculation parameters (the queried fixed remaining usage time length, the current output power and the matched output power) corresponding to the first battery voltage threshold value of the current battery voltage drop under the current output power of the battery of each battery type into the first time length calculation formula to calculate the theoretical time length corresponding to each battery type.

The comparison module 408 is configured to compare the differences between the theoretical durations corresponding to all kinds of battery types and the target duration to obtain the battery type corresponding to the theoretical duration with the smallest difference, as the calibration battery type.

The calculated theoretical remaining use time length is specifically obtained by substituting the target output power, the queried fixed remaining use time length and the matched output power of the screened target output power into the first time length calculation formula.

Still further alternatively, the remaining in-use time length calibration value corresponding to the target battery is equal to a ratio of an actual in-use time length when the battery voltage of the target battery drops by a predetermined second battery voltage threshold value to the target battery voltage at the target output power to a theoretical in-use time length when the battery voltage of the target battery drops by the second battery voltage threshold value to the target battery voltage at the target output power.

Still further alternatively, the actual remaining usage time length of the target battery at the target battery voltage and the target output power is equal to a product of the theoretical remaining usage time length calculated by calibrating the battery type, the target battery voltage, and the target output power and the remaining usage time length calibration value corresponding to the target battery.

It can be seen that, in this alternative embodiment, after the initial battery type of the battery is determined by the default determining manner, the determined initial battery type is further calibrated by comparing the recorded actual duration with the calculated difference value of the plurality of theoretical durations, which improves the accuracy of the finally determined battery type and is beneficial to further improving the accuracy of calculating the remaining service duration of the battery according to the accurate battery type. In addition, after the battery type of the battery is calibrated, the calculated theoretical remaining use time length is calibrated through the calculated remaining use time length calibration value, so that the actual remaining use time length of the battery is obtained, and the accuracy and stability of the calculated remaining use time length of the battery after the battery type is calibrated are improved.

As another alternative embodiment, as shown in fig. 7, the first computing module 402 may include:

the second obtaining sub-module 4024 is configured to obtain the current output power and the current battery voltage of the target battery when the determination mode of the type of the target battery is the calibration determination mode or the direct determination mode.

A second calculation submodule 4025, configured to calculate a long calibration value corresponding to a remaining usage time of the target battery at the current output power and the current battery voltage; and calculating the theoretical remaining use duration of the target battery under the current battery voltage and the current output power according to the current output power, the current battery voltage and the target battery type.

The theoretical remaining use duration of the target battery under the current battery voltage and the current output power can be specifically calculated by substituting corresponding calculation parameters into the first time duration calculation formula.

The second calculating submodule 4025 is further configured to calculate a remaining usage duration of the target battery at the current output power and the current battery voltage according to a second duration calculation formula, a remaining usage duration of the target battery at the current output power and the current battery voltage, and a theoretical remaining usage duration of the target battery at the current output power and the current battery voltage.

It can be seen that, after the battery type of the battery is accurately determined, the device described in fig. 7 can also calibrate the calculated theoretical remaining use time length by using the calculated remaining use time length calibration value, so as to obtain the remaining use time length of the battery, and improve the accuracy of the calculated remaining use time length of the battery. In addition, the efficiency of calculating the remaining use period of the battery can be improved. In addition, the method can be suitable for calculating the residual service life of the battery of various battery types, and is beneficial to improving the applicability of the residual service life determining device of the battery.
