Referring to fig. 2, fig. 2 is a schematic flow chart illustrating another method for determining a remaining battery operating time according to an embodiment of the present 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 from the device, or may be installed or integrated in the device, and further, the device may be a lighting device, in some application scenarios, multiple types of batteries may be connected to the lighting device, or multiple types of batteries may be connected to a control box connected to the lighting device, and of course, the device may also be a lighting device charging box, a charging battery box, a sound recording device, a shooting device, a mobile terminal (e.g., a mobile phone, a tablet), and the like, and the embodiment of the present invention is not limited.

It should be noted that the method described in fig. 2 is applicable to a scenario where the battery type of the battery used by the device cannot be directly determined. As shown in fig. 2, the remaining usage period 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 a target battery type of a target battery currently used by the target device.

In this 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 designated battery type, or may be one of a plurality of battery types.

202. And the determining device matches the remaining service life calculating mode corresponding to the determining mode of the target battery type according to the determining mode of the target battery type.

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

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

204. The determination means selects a matching output power of the present output power from a plurality of predetermined output powers, and selects a matching battery voltage of the present battery voltage from a plurality of predetermined battery voltages.

The screened matching output power of the current output power may be the matching output power which is screened from the predetermined plurality of output powers and is equal to the current output power or the matching output power of which the difference value with the current output power is less than or equal to a preset power threshold, or may be the maximum output power which is less than the current output power and the minimum output power which is greater than the current output power in the predetermined plurality of output powers, which is not limited in the embodiment of the present invention. The screened matching battery voltage of the current battery voltage may be a matching battery voltage which is screened from the plurality of battery voltages and is equal to the current battery voltage or a matching battery voltage of which the difference value with the current battery voltage is less than or equal to a preset voltage threshold, or a maximum battery voltage which is less than the current battery voltage and a minimum battery voltage which is greater than the current battery voltage in the plurality of predetermined battery voltages, which is not limited in the embodiment of the present invention.

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

And the fixed residual service life is the residual service life of the inquired battery with the target battery type under the matched output power and the matched battery voltage.

It should be noted that, when the matching output power is the matching output power which is selected from the predetermined plurality of output powers and is equal to the current output power or the matching output power whose difference with the current output power is less than or equal to the preset power threshold, and the matching battery voltage is the matching battery voltage which is selected from the plurality of battery voltages and is equal to the current battery voltage or the matching battery voltage whose difference with the current battery voltage is less than or equal to the preset voltage threshold, the determining device may directly determine the inquired fixed remaining usage time as the initial remaining usage time of the target battery.

In this embodiment of the present invention, as an optional implementation manner, the screening, by the determining apparatus, the matching output power of the current output power from a plurality of predetermined output powers may include:

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

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

T_d＝T₂+(T₁-T₂)*(P_d-P₁)/(P₂-P₁)；

wherein, T_dFor the calculated initial remaining usage period of the target battery, P_dFor the current output power, T₁For a first fixed remaining service life, T, of the battery of the target battery type at the first matched output power and the matched battery voltage₂For a second fixed remaining useful time, P, of the battery of the target battery type at a second matched output power and matched battery voltage₁For the first matched output power, P₂The output power is second matched.

In this alternative embodiment, the determining means may directly look up the required fixed remaining usage period from the pre-generated remaining usage period data corresponding to the batteries of different battery types at different battery voltages and different output powers. The remaining usage duration 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 maximum battery voltage (i.e., a first matched battery voltage) smaller than the current battery voltage and a minimum battery voltage (i.e., a second matched battery voltage) larger than the current battery voltage among the predetermined plurality of battery voltages, the determining device may query two groups of first fixed remaining usage durations and second fixed remaining usage durations, and the determining device may calculate the first initial remaining usage duration and the second initial remaining usage duration of the target battery by using the first time duration calculation formula and by respectively combining each group of the first fixed remaining usage duration and the second fixed remaining usage duration. Thereafter, the determination means may finally calculate the initial remaining usage period of the target battery by:

the determining device takes the average value of the first initial remaining use time length and the second initial remaining use time length as the finally calculated initial remaining use time length of the target battery; alternatively, the first and second electrodes may be,

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 a product of the first weight value and the first initial remaining use time and a product of the second weight value and the second initial remaining use time;

the determination 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 finally calculated initial remaining usage period of the target battery.

Optionally, the weight value corresponding to the matched battery voltage may be determined by a voltage difference between the matched 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 remaining use duration of the first group is obtained by inquiring first matched battery voltage, first matched output power and a target battery type, and the second fixed remaining use duration of the first group is obtained by inquiring first matched battery voltage, second matched output power and the target battery type; the first fixed remaining usage duration of the second group is obtained through querying of the second matched battery voltage, the first matched output power and the target battery type, and the second fixed remaining usage duration of the second group is obtained through querying of the second matched battery voltage, the second matched output power and the target battery type.

Therefore, by implementing the method described in the embodiment of the invention, the battery type of the battery can be determined as the default battery type under the condition that the battery type of the battery cannot be directly determined, and the remaining service life of the battery is calculated through the time length calculation formula corresponding to the default battery type.

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

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

In this alternative embodiment, the predetermined first battery voltage threshold may be a voltage value V that passes through a predetermined interval_gapAnd the number of intervals N is determined, and the first cell voltage threshold is equal to N V_gapE.g. 6 x 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 battery voltage drop is continuously recorded and is waited until the current battery voltage drops by the predetermined first battery voltage threshold, and the target time duration may be recorded by the associated timing module.

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

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

208. The determining device compares the difference between the theoretical time length corresponding to all the types of battery types and the target time length to obtain the battery type corresponding to the theoretical time length with the minimum difference, 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 a default battery type to a calibration battery type.

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

Therefore, the optional embodiment can also calibrate the determined initial battery type by comparing the recorded actual time length with the calculated difference values of the plurality of theoretical time lengths after the initial battery type of the battery is determined in the default determination mode, so that the accuracy of the finally determined battery type is improved, and the accuracy of calculating the residual service time length of the battery according to the accurate battery type is further improved.

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

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

The target battery voltage may be any battery voltage obtained after every predetermined second battery voltage threshold value is decreased 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 residual service time of the target battery under the target battery voltage and the target output power according to the theoretical residual service time calculated by calibrating the battery type, the target battery voltage and the target output power and the residual service time calibration value corresponding to the target battery.

In this optional embodiment, it is further optional that the calibration value R of the remaining service time length corresponding to the target battery is set_typeEqual to the ratio of the actual service time period T _ real when the battery voltage of the target battery drops by the predetermined second battery voltage threshold to the target battery voltage at the target output power to the theoretical service time period T _ type when the battery voltage of the target battery drops by the second battery voltage threshold to the target battery voltage at the target output power, that is: calibration value R of residual service time corresponding to target battery_type＝T_real/T_type。

In this optional embodiment, it is further optional that the actual remaining usage time 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 time period T _ remaining calculated by calibrating the battery type, the target battery voltage, and the target output power, and the remaining usage time period calibration value R corresponding to the target battery_typeThe product of (a) and (b), that is: t _ real _ remaining ═ T _ remaining R_type。

It should be noted that the principle of "calibrating the calculated theoretical remaining usage time according to the remaining usage time calibration value to obtain the actual remaining usage time" described in the above steps 210 to 211 may also be applied to the calculation of the actual remaining usage time of other batteries of the above calibrated battery type or batteries of other battery types, so that the continuous calibration of the remaining usage time of the battery can be realized, and the accuracy and stability of the calculated remaining usage time of the battery can be further improved.

Therefore, in the optional embodiment, after the battery type of the battery is calibrated, the calculated theoretical remaining service life is calibrated through the calculated remaining service life calibration value, so that the actual remaining service life of the battery is obtained, and the accuracy and the stability of the calculated remaining service life of the battery after the battery type is calibrated are improved. In addition, the calibration of the remaining service life of other batteries of which the battery types are the same as the calibration battery types can be realized, and the accuracy and the stability of the calculated remaining service life of the battery can be further improved through continuous calibration.

In yet another optional embodiment, before obtaining the target calculation parameter corresponding to the target device according to the remaining usage time calculation manner and calculating the remaining usage time of the target battery according to the target calculation parameter, preferably, before determining the target battery type of the target battery currently used by the target device, the method may further include the operations 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 determination means calculates a period of time during which the battery of the battery type is used by each remaining battery voltage down to the minimum battery voltage at each output power as a fixed remaining period of time of use of the battery type at each output power and each remaining battery voltage.

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

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

the determination means acquires or records the battery voltage of the battery type at each output power every 1V drop from the initial battery voltage_gapAnd the used time length is obtained, the used time length corresponding to each battery voltage interval is obtained, and the sum of the used time lengths corresponding to all the battery voltage intervals smaller than each residual battery voltage is calculated and is used as the fixed residual used time length of the battery type under each output power and each residual battery voltage.

Therefore, the optional embodiment can also calculate the fixed remaining service life of the battery type under each output power and each remaining battery voltage of the batteries of different types in advance, so that the required calculation data can be rapidly and accurately inquired when the theoretical remaining service life or the theoretical time of the battery is calculated, and the efficiency of calculating the remaining service life of the battery of the equipment is improved.

Therefore, by implementing the method described in the embodiment of the invention, the battery type of the battery can be determined as the default battery type under the condition that the battery type of the battery cannot be directly determined, and the remaining service life of the battery is calculated through the time length calculation formula corresponding to the default battery type. In addition, after the initial battery type of the battery is determined in a default determination mode, the determined initial battery type is calibrated by comparing the recorded actual time length with the calculated difference values of the plurality of theoretical time lengths, so that the accuracy of the finally determined battery type is improved, and the accuracy of calculating the residual service 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 service life is calibrated through the calculated remaining service life calibration value, so that the actual remaining service life of the battery is obtained, and the accuracy and the stability of the calculated remaining service life of the battery after the battery type is calibrated are improved. In addition, the calibration of the remaining service life of other batteries with the same battery type as the calibration battery type and batteries with other battery types can be realized, and the accuracy and the stability of the calculated remaining service life of the batteries can be further improved through continuous calibration. In addition, the fixed remaining service time of the battery type under each output power and each remaining battery voltage of the batteries of different types can be calculated in advance, so that the required calculation data can be inquired quickly and accurately when the theoretical remaining service time or the theoretical time of the battery is calculated, and the efficiency of calculating the remaining service time of the battery of the equipment is improved. In addition, the calculation and calibration of the remaining service life of the batteries with different battery types can be realized, and the applicability of the method described in the embodiment of the invention is improved.

For example two, 3 battery types including the same battery voltage range but different battery capacities were used as the battery types, and 12V to 16.8V (i.e., 12000mV to 16800mV) was used as the battery voltage range, and V was used as the interval voltage value_gapThe example of the output power of 50mV is 6 output powers with a maximum output power of 60W and an interval of 10W, which is as follows:

the 3 battery types include BAT _ a (maximum capacity), BAT _ B (medium capacity) and BAT _ C (minimum capacity), respectively;

according to the interval voltage value V_gapSampling a battery voltage range (12000mV-16800mV) to obtain 97 battery voltages, specifically 12000mV, 12050mV, 12100mV, 12150mV,. once, 16750mV and 16800 mV;

the battery of each battery type requires the acquisition of basic data at 6 output powers and the composition of a time curve based on the basic data acquired at each output power, that is: power _1 ═ 10W, the corresponding curve is curve _ 1; power _2 ═ 20W, the corresponding curve is curve _ 2; power _3 ═ 30W, the corresponding curve is curve _ 3; power _4 ═ 40W, the corresponding curve is curve _ 4; power _5 ═ 50W, the corresponding curve is curve _ 5; power _6 ═ 60W, the corresponding curve is curve _ 6.

One set of basic data is a data table, specifically the length of time that a type of battery can be used at a particular output power and a specified battery voltage. For example: in the case where the output power of a battery of battery type BAT _ a is power _1, the remaining usage period at the lower limit battery voltage of 12000mV is 0 seconds, the remaining usage period at the battery voltage of 12050mV is 50 seconds, the remaining usage period at the battery voltage of 12100mV is 150 seconds,.. and the remaining usage period at the battery voltage of 16800mV is 10000 seconds, the set of basic data may be expressed as: base _ data [97] - {0,50, 150.., 10000 }.

Specifically, the method comprises the following steps: when the remaining service life of each type of battery under the specified output power and the specified battery voltage is calculated, the battery voltage can be recorded from the highest battery voltage to each drop V under the specified output power_gapThe used time is long until the battery voltage is reduced to the minimum battery voltage, and the shutdown is carried out every time V is reduced_gapForming a battery voltage interval, wherein the used time length of each battery voltage interval is recorded, under the specified output power, the residual used time length of each battery voltage obtained by the battery through sampling is equal to the sum of the used time lengths of all battery voltage intervals lower than the battery voltage, and for example, the residual used time length of the battery voltage of 16800mV is the sum of the used time lengths of all battery voltage intervals; the remaining service life of the cell voltage of 12050mV is then the service life of the cell voltage interval of 12050mV to 12000 mV. Through this process, a fixed remaining usage period for each type of battery at each output power and each battery voltage can be obtained, wherein the fixed remaining usage period for each type of battery at each output power includes the remaining usage period for each battery voltage, such as 6 output powers, and 3 types of batteries totaling 18 sets of remaining usage periods.

In practical applications, when a device is powered on, the device cannot directly determine the battery type of the battery used by the device, and therefore, the battery type of the battery mounted by default by the device is the default battery type, which is described by 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 current of the current output power is between current _4 and current _ 5. Under the current battery voltage volt, the remaining usage time lengths corresponding to the curve live _4 and the curve live _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 remaining usage time lengths t under the current output power and the current battery voltage volt can be calculated according to a linear formula. Wherein the linear calculation formula is: t-t 5+ (t4-t5) (power-power _4)/(power _5-power _4), the device may take the calculated t value as the initial remaining usage period of the battery.

After the device is used for a period of time, the battery voltage of the battery drops by 6V_gapThe duration used is t _ real, and batteries of 3 types (BAT _ A, BAT _ B and BAT _ C) are in this case (6V drops)_gap) The corresponding theoretical time lengths are t _ A, t _ B and t _ C respectively, wherein t _ A, t _ B and t _ C are calculated through the linear calculation formula. The device compares t _ real with t _ A, t _ B and t _ C calculated by the above linear calculation formula, and if the t _ real is closer to the t _ real, it indicates that the battery type of the currently used battery is closer to the t _ real, for example, if t _ a is closer to t _ real, it may indicate that the current battery type is BAT _ a, and the subsequent algorithm will calculate the remaining service life by using the basic data corresponding to BAT _ a. This procedure can be understood as a calibration procedure for the battery type and by this procedure the device can obtain that the actual usage duration of the battery at this stage is t _ real and the theoretical usage duration is t _ a, the ratio of the actual usage duration to the theoretical usage duration is rate, and rate is t _ real/t _ a. When the battery voltage is reduced by 6V_gapThe theoretical remaining usage duration of the battery voltage is t _ remaining, and the actual remaining usage duration is t _ real _ remaining, and t _ real _ remaining is t _ remaining rate.

After the battery type of the battery is accurately identified, the corresponding algorithm can continuously perform time length calibration so as to ensure that the theoretical remaining use time length does not have too large deviation from the actual remaining use time length. The specific calibration method comprises the following steps: the device has recently dropped 6V according to the battery_gapThe ratio rate of the actual usage time length corresponding to the battery voltage interval and the theoretical usage time length calculated by the linear calculation formula is t _ real/t _ a, and then the actual remaining usage time length t _ real _ remaining is calculated by the rate and the calculated theoretical remaining usage time length of the current battery voltage, and the t _ real _ remaining is t _ remaining rate. Such as: if the current battery voltage is 14000mV, the value sources of t _ real and t _ A are the actual use time and the calculated theoretical use time when the battery voltage is reduced from 14300mV to 14000 mV; if the battery voltage drops to 13950mV, the corresponding battery voltage interval is the battery voltage interval in which 14250mV drops to 13950 mV.
