[0002] With the continuous development of technology and the continuous improvement of battery performance, batteries, as an important energy storage device, have been widely used in various fields. In particular, zinc-nickel batteries have the advantages of high energy density, good cycle performance and environmental protection. The battery packs composed of them can meet more application scenarios, so they have received more and more attention. However, there are some problems in the traditional charging and discharging methods of zinc-nickel batteries, such as uneven charging amounts of sub-batteries in the battery pack and unclear priority order of sub-batteries during discharge. The lack of an effective control system will also affect the performance and lifespan of the battery.

[0057] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. The components of the embodiments of the present application described and illustrated herein can be arranged and designed in various different configurations. Therefore, the detailed description of the embodiments of the present application provided in the accompanying drawings is not intended to limit the scope of the present application claimed, but merely represents the selected embodiments of the present application. All other embodiments obtained by those skilled in the art based on the embodiments of the present application without creative efforts belong to the scope of protection of the present application.

[0058] It should be noted that similar reference numerals and letters denote similar items in the following drawings. Therefore, once an item is defined in one drawing, it does not need to be further defined and explained in subsequent drawings. At the same time, in the description of the present application, the terms "first", "second", etc. are only used for descriptive distinction and cannot be understood as indicating or implying relative importance.

[0059] Please refer to Figure 1 , Figure 1 which is a flowchart of the charging and discharging method of a zinc-nickel battery in some embodiments of the present application. The charging and discharging method of the zinc-nickel battery is used in a terminal device, such as a computer, a mobile phone, etc. The charging and discharging method of the zinc-nickel battery includes the following steps:

[0060] S11. Obtain the planned charging duration data of the zinc-nickel battery and the battery performance data of each sub-battery;

[0061] S12. Obtain the charging power data of the zinc-nickel battery, and process it in combination with the battery performance data to obtain the estimated duration data of the zinc-nickel battery charging;

[0062] S13. Compare the estimated duration data with the planned charging duration data to obtain a charging duration relative index, and compare the charging duration relative index with a preset charging duration relative index threshold to obtain an estimated charging state;

[0063] S14. Judge the estimated charging state, obtain a corresponding preset matching charging scheme, and charge the zinc-nickel battery according to the matching charging scheme.

[0064] It should be noted that when zinc-nickel batteries are in use, different battery capacities are selected according to different application scenarios. A single battery often cannot meet the requirements of the scenario. Therefore, batteries are often combined to form a battery pack for use. Therefore, in this embodiment, the zinc-nickel battery refers to a zinc-nickel battery pack with sub-batteries; when charging a zinc-nickel battery, it is often encountered that the battery is charged according to a preset fixed duration. For example, the charger has to leave at a fixed time point and start a journey. In this case, in order to better charge each sub-battery in the battery pack, it is necessary to obtain the planned charging duration data, charging power data, and battery performance data of each sub-battery of the zinc-nickel battery, process the charging power data and battery performance data to obtain the estimated duration data, then divide the estimated duration data by the planned charging duration data to obtain the charging duration relative index, compare the charging duration relative index with a threshold value to obtain the estimated charging state, and finally obtain the corresponding preset matching charging scheme according to the estimated charging state and charge according to the preset matching charging scheme, so that each sub-battery can be charged evenly, and the charging is more reasonable and effective.

[0065] Please refer to Figure 2 , Figure 2 is a flowchart for obtaining the planned charging duration data and battery performance data of a zinc-nickel battery charge and discharge method provided by an embodiment of the present application. According to an embodiment of the present invention, the obtaining of user feature data, generating a user consumption feature portrait according to the user feature data, and extracting user consumption intention data according to the user consumption feature portrait specifically include:

[0066] S21. Obtain the planned charging duration data of the zinc-nickel battery and the battery performance data of each sub-battery;

[0067] S22. The battery performance data includes sub-battery standard capacity data, sub-battery remaining life ratio data, sub-battery remaining power data, and sub-battery charging efficiency data.

[0068] It should be noted that obtaining the planned charging duration data of the zinc-nickel battery means that before charging, users often have a general plan for the charging time according to their time plan or itinerary plan, that is, determine the charging duration data; a zinc-nickel battery is composed of multiple sub-batteries. Obtaining the battery performance data of the sub-batteries includes sub-battery standard capacity data, sub-battery remaining life ratio data, sub-battery remaining power data, and sub-battery charging efficiency data. The sub-battery standard capacity data refers to the standard power capacity value of the sub-battery. During the use of the sub-battery, its capacity will gradually decrease with the increase of the number of charge and discharge cycles and the influence of time factors. The sub-battery remaining life ratio data refers to the ratio of the actual maximum capacity value of the sub-battery to the standard capacity; the sub-battery remaining power data refers to the remaining capacitance value in the sub-battery.

[0069] Please refer toFigure 3 , Figure 3 is a flowchart for obtaining estimated duration data of a zinc-nickel battery charge and discharge method provided by an embodiment of the present application. According to an embodiment of the present invention, charging power data of a zinc-nickel battery is obtained, and in combination with the battery performance data, estimated duration data for charging the zinc-nickel battery is processed and obtained, specifically including:

[0070] S31. Query a preset battery charge and discharge performance database according to the sub-battery remaining life proportion data to obtain a sub-battery charging duration correction index, and calculate an effective charging duration correction index for the zinc-nickel battery according to the sub-battery charging duration correction index;

[0071] S32. Calculate the average value of the sub-battery charging efficiency data to obtain effective charging efficiency data;

[0072] S33. Obtain the charging power data of the zinc-nickel battery, and multiply the charging power data by the effective charging efficiency data to obtain effective charging power data;

[0073] S34. Input the battery standard capacity data, sub-battery remaining life proportion data, sub-battery remaining power data, effective charging power data, and effective charging duration correction index into a preset zinc-nickel battery charging duration estimation model for processing to obtain estimated duration data;

[0074] The calculation formula for the estimated duration data in the zinc-nickel battery charging duration estimation model is:

[0075]

[0076] where Y s is the estimated duration data, Y x is the effective charging duration correction index, Y g is the effective charging power data, D bi , S si , S di are respectively the battery standard capacity data, sub-battery remaining life proportion data, and sub-battery remaining power data of the i-th sub-battery, n is the number of sub-batteries in the preset zinc-nickel battery, and α is a preset characteristic coefficient (the characteristic coefficient is obtained by querying a preset zinc-nickel battery charge and discharge platform).

[0077] It should be noted that to obtain the charging power data of the zinc-nickel battery, the charging power refers to the average charging power at the battery terminal when the power source charges the battery; after the data of the remaining life ratio of the sub-battery is determined, the charging duration correction index of the sub-battery is obtained by querying the preset battery charge-discharge performance database. The battery charge-discharge performance database is preset and is obtained through training and calculation of a large amount of historical data. The battery charge-discharge performance database contains the data of the remaining life ratio of the sub-battery and the corresponding charging duration correction index of the sub-battery. The charging duration correction index of the sub-battery refers to the index that affects the time required for the sub-battery to be fully charged due to its own performance changes. The average value is obtained by adding up the charging duration correction indexes of each sub-battery to obtain the effective charging duration correction index; when charging the zinc-nickel battery, due to the inconsistent performance states of each sub-battery, after the input charging power is determined, the charging efficiency data of the sub-battery will also be different. The charging efficiency data of the sub-battery refers to the ratio data of the charging input power converted into the battery power growth power when charging the sub-battery; the charging power data refers to the power data directly input to the battery by the power source through the power charging device. During the charging process, the charging power data will change due to different battery conditions. Therefore, the average value is recorded as the effective charging power data after calculation. The effective charging power data can better reflect the charging power data of the zinc-nickel battery; the estimated duration data refers to an evaluation data of the time required for the current battery to be charged from the remaining power to the full power; the zinc-nickel battery charging duration estimation model is obtained through training with a large amount of historical data, and the estimated duration data can be calculated through this model.

[0078] Please refer to Figure 4 , Figure 4 Figure 4 is a flowchart for obtaining the estimated charging state of a zinc-nickel battery charge-discharge method provided by an embodiment of the present application. According to an embodiment of the present invention, obtaining the charging duration relative index by comparing the estimated duration data with the planned charging duration data, and comparing the charging duration relative index with a preset charging duration relative index threshold to obtain the estimated charging state specifically includes:

[0079] S41. Divide the estimated duration data by the planned charging duration data to obtain the charging duration relative index;

[0080] S42. Compare the charging duration relative index with a preset charging duration relative index threshold to obtain the estimated charging state, including a full state or an unfilled state;

[0081] S43. If the charging duration relative index is greater than or equal to the preset charging duration relative index threshold, the estimated charging state is a chargeable state;

[0082] S44. If the charging duration relative index is less than the preset charging duration relative index threshold, the estimated charging state is a non-chargeable state.

[0083] It should be noted that, in order to more intuitively compare the estimated duration data and the planned charging duration data, the charging duration relative index is obtained by dividing the two. After comparing the charging duration relative index with the threshold, the estimated charging state is obtained. In this embodiment, the charging duration relative index threshold is set to (0, 1), which means the state of not being fully chargeable; when it is greater than or equal to 1, it is in a fully chargeable state. That is, when the charging duration relative index is greater than or equal to the preset charging duration relative index threshold, it indicates that the planned charging duration is greater than or equal to the estimated duration data, and the zinc-nickel battery can be fully charged; when the charging duration relative index is less than the preset charging duration relative index threshold, it indicates that the planned charging duration is less than the estimated duration data, and the zinc-nickel battery cannot be fully charged in this charging.

[0084] According to the embodiment of the present invention, judging the estimated charging state and obtaining the corresponding matching charging scheme, and charging the zinc-nickel battery according to the matching charging scheme specifically includes:

[0085] If the estimated charging state is a fully chargeable state, the zinc-nickel battery is charged in sequence according to the circuit connection order of the sub-batteries;

[0086] If the estimated charging state is a non-fully chargeable state, the zinc-nickel battery is charged according to the dynamic evaluation mode.

[0087] It should be noted that when the zinc-nickel battery can be fully charged, each sub-battery can achieve the best charging effect. Therefore, it can be charged in sequence according to the circuit connection order of the sub-batteries in the zinc-nickel battery; when the estimated charging state is a non-fully chargeable state, it means that all sub-batteries cannot be fully charged. In order to enable each sub-battery to be better charged, a dynamic evaluation will be carried out before each charging in combination with the situation of the sub-batteries to perform optimal allocation of the charging amount. When the battery capacity permits, each battery will have equal power after charging.

[0088] According to the embodiment of the present invention, the dynamic evaluation mode specifically includes:

[0089] Calculating the remaining total power data of the zinc-nickel battery according to the remaining power data of the sub-battery and the preset number of sub-batteries;

[0090] Calculating the real-time capacity data of the zinc-nickel battery according to the standard capacity data of the sub-battery, the remaining life ratio data of the sub-battery and the preset number of sub-batteries;

[0091] Calculating the estimated power ratio data according to the charging power data, the planned charging duration data, the remaining total power data and the real-time capacity data;

[0092] Comparing the estimated power ratio data with the remaining life ratio data of the sub-battery by the threshold;

[0093] If the remaining life ratio data of the sub-batteries are all greater than the estimated power ratio data, the zinc-nickel battery will charge the power ratio data of the sub-batteries to the estimated power ratio data in the circuit connection order of the sub-batteries;

[0094] If some of the remaining life ratio data of the sub-batteries are less than or equal to the estimated power ratio data, they are recorded as priority charge sub-batteries. The priority charge sub-batteries are charged to full in ascending order of the remaining life ratio data of the sub-batteries, and the remaining sub-batteries are redistributed according to a preset method.

[0095] It should be noted that the number of sub-batteries in the zinc-nickel battery is preset according to user requirements. Therefore, the total remaining power data of the zinc-nickel battery is obtained by adding up the remaining power data of each sub-battery;

[0096] The real-time capacity data of the zinc-nickel battery is calculated based on the standard capacity data of the sub-battery, the remaining life ratio data of the sub-battery, and the preset number of sub-batteries. The calculation formula is:

[0097]

[0098] Among them, S r is the real-time capacity data, D bi 、S siare the battery standard capacity data and the remaining life percentage data of the ith sub-battery, respectively, and n is the number of sub-batteries in the preset zinc-nickel battery; as the capacity of the battery changes over time, the real-time capacity data refers to the latest capacity data of the zinc-nickel battery; the charging power data is multiplied by the planned charging time data to obtain the charging capacity data, the charging capacity data is added to the remaining total power data to obtain the estimated total power data of the zinc-nickel battery after charging, and the estimated total power data is divided by the real-time capacity data to obtain the estimated power percentage data; the estimated power percentage data is compared with the remaining life percentage data of the sub-battery by a threshold value, and if the remaining life percentage data of the sub-battery are all greater than the estimated power percentage data, it means that each sub-battery cannot be fully charged this time, and then the circuit connection of the sub-battery is connected according to the circuit connection of the sub-battery. The sub-batteries are charged in sequence, and the power percentage data of each sub-battery is charged to the estimated power percentage data to ensure the consistency of sub-battery charging; if the remaining life percentage data of some sub-batteries is less than or equal to the estimated power percentage data, it means that this part of the batteries can be fully charged and recorded as priority charging sub-batteries, and the remaining sub-batteries are remaining sub-batteries. The priority charging sub-batteries are charged first, and then the priority charging amount of the priority charging sub-batteries is counted, and the charging amount data is subtracted from the priority charging amount to obtain the charging amount to be allocated, and the charging amount to be allocated is added to the sub-battery remaining power data of the remaining sub-batteries to obtain the total estimated achievable power of the remaining sub-batteries, and the total estimated achievable power is divided by the number of remaining sub-batteries to obtain the sub-battery achievable power, and the remaining sub-batteries are charged to the battery achievable power in the sub-battery connection order.

[0099] According to an embodiment of the present invention, it also includes:

[0100] The actual capacity data of the sub-battery is obtained by multiplying the standard capacity data of the sub-battery by the remaining life percentage data of the sub-battery;

[0101] Dividing the sub-battery remaining power data by the sub-battery actual capacity data to obtain real-time remaining power percentage data of each sub-battery;

[0102] After sorting the real-time remaining power percentage data in descending order, obtaining the preceding real-time remaining power percentage data and the minimum real-time remaining power percentage data;

[0103] Subtract the minimum real-time remaining power percentage data from the previous real-time remaining power percentage data to obtain the real-time remaining power percentage difference data of each sub-battery;

[0104] Comparing the real-time remaining power ratio difference data with a preset real-time remaining power ratio difference threshold to obtain a discharge capacity difference state;

[0105] If the real-time remaining power ratio difference data is less than the preset real-time remaining power ratio difference threshold, the discharge amount difference state is normal, and the preset equal-proportional discharge mode is started accordingly;

[0106] If the real-time remaining power ratio difference data is greater than or equal to the preset real-time remaining power ratio difference threshold, the discharge amount difference state is an abnormal state, and the preset sequential discharge mode is correspondingly started.

[0107] It should be noted that the capacity of the zinc-nickel battery will change during use. Therefore, when using it, the actual capacity shall prevail, and the actual capacity data of the sub-battery needs to be obtained; when distributing the discharge of the zinc-nickel battery, in order to extend the service life of the battery, balanced discharge shall be carried out, and no single sub-battery shall be over-discharged. The balanced discharge only requires that the difference in the remaining power ratio data between sub-batteries shall not be greater than the preset value; in order to achieve the balanced discharge of each sub-battery, the real-time remaining power ratio data will be sorted and compared to judge; the previous real-time remaining power ratio data refers to the real-time remaining power ratio data except the minimum real-time remaining power ratio data in the sorted real-time remaining power ratio data; the real-time remaining power ratio difference data is obtained by successively subtracting the minimum real-time remaining power ratio data from the previous real-time remaining power ratio data, and then compared with the preset real-time remaining power ratio difference threshold to obtain the discharge amount difference state; if the real-time remaining power ratio difference data is less than the preset real-time remaining power ratio difference threshold, it indicates that the discharge between sub-batteries is balanced, which is a normal state, and the preset equal-ratio discharge mode is correspondingly started; if the real-time remaining power ratio difference data is greater than or equal to the preset real-time remaining power ratio difference threshold, it indicates that the discharge between sub-batteries is unbalanced, and it needs to be executed according to the preset sequential discharge mode. In this actual example, the real-time remaining power ratio difference threshold is set to 0.15.

[0108] It is worth mentioning that the equal-ratio discharge mode specifically includes:

[0109] Obtain the estimated power consumption data;

[0110] Calculate the power ratio data of each sub-battery according to the remaining power data of the sub-battery;

[0111] Multiply the power ratio data of each sub-battery by the estimated power consumption data to obtain the discharge amount data of each sub-battery;

[0112] Each sub-battery discharges according to the discharge amount data in the preset connection order of the sub-batteries in the battery.

[0113] It should be noted that before obtaining the estimated power consumption data and executing the equal - ratio discharge mode, the magnitudes of the estimated power consumption data and the remaining battery power data are judged, and the estimated power consumption data should be less than the remaining battery power data; the remaining battery power data refers to the sum of the remaining power data of the sub - batteries; the power proportion data of each sub - battery is calculated based on the remaining power data of the sub - batteries. The calculation method is: divide the remaining power data of the sub - battery by the remaining battery power data, and then multiply the power proportion data by the estimated power consumption data to obtain the discharge amount data of each sub - battery, and each sub - battery discharges according to the corresponding discharge amount data.

[0114] It is worth mentioning that the sequential discharge mode specifically includes:

[0115] Compare the real - time remaining power proportion difference data with the preset real - time remaining power proportion difference threshold to obtain the priority discharge sub - battery;

[0116] If the real - time remaining power proportion difference data is greater than the preset real - time remaining power proportion difference threshold, the corresponding sub - battery is the priority discharge sub - battery;

[0117] If the real - time remaining power proportion difference data is less than or equal to the preset real - time remaining power proportion difference threshold, the corresponding sub - battery is the equal - ratio discharge sub - battery;

[0118] Multiply the real - time remaining power proportion difference data corresponding to the priority discharge sub - battery by the remaining power data of the sub - battery to obtain the priority discharge amount data;

[0119] After the priority discharge sub - battery discharges preferentially according to the priority discharge amount data, the remaining estimated power consumption data is obtained;

[0120] Then the priority discharge sub - battery and the equal - ratio discharge sub - batteries perform equal - ratio discharge according to the remaining estimated power consumption data.

[0121] It should be noted that when the real - time remaining power proportion difference data is greater than the preset real - time remaining power proportion difference threshold, it indicates that the discharge is unbalanced. Mark the sub - battery with more remaining power corresponding to the remaining power proportion difference data in this case as the priority discharge sub - battery, and it discharges preferentially during discharge. The calculation method of the priority discharge amount is: multiply the real - time remaining power proportion difference data by the remaining power data of the sub - battery; after the priority discharge sub - battery discharges, subtract the priority discharge amount from the estimated power consumption data to obtain the remaining estimated power consumption data, and then the priority discharge sub - battery after priority discharge and the equal - ratio discharge sub - batteries perform equal - ratio discharge together.

[0122] The present invention also discloses a zinc - nickel battery charge - discharge system, including a memory and a processor. The zinc - nickel battery charge - discharge method program is stored in the memory, and when the zinc - nickel battery charge - discharge method program is executed by the processor, the following steps are implemented:

[0123] Obtain the planned charging duration data of the zinc-nickel battery and the battery performance data of each sub-battery;

[0124] Obtain the charging power data of the zinc-nickel battery, and process it in combination with the battery performance data to obtain the estimated duration data of the zinc-nickel battery charging;

[0125] Compare the estimated duration data with the planned charging duration data to obtain a charging duration relative index, and compare the charging duration relative index with a preset charging duration relative index threshold to obtain an estimated charging state;

[0126] Judge the estimated charging state, obtain a corresponding preset matching charging scheme, and charge the zinc-nickel battery according to the matching charging scheme.

[0127] It should be noted that when the zinc-nickel battery is in use, different battery capacities will be selected according to different application scenarios. A single battery often cannot meet the requirements of the scenario. Therefore, the batteries are often combined to form a battery pack for use. Therefore, in this embodiment, the zinc-nickel battery refers to a zinc-nickel battery pack with sub-batteries; when charging the zinc-nickel battery, it often encounters the situation of charging the battery according to a preset fixed duration. For example, the charger has to leave at a fixed time point and start a journey. In this case, in order to better charge each sub-battery in the battery pack, it is necessary to obtain the planned charging duration data, charging power data and the battery performance data of each sub-battery of the zinc-nickel battery, process the estimated duration data according to the charging power data and the battery performance data, then divide the estimated duration data by the planned charging duration data to obtain a charging duration relative index, compare the charging duration relative index with a threshold to obtain an estimated charging state, and finally obtain a corresponding preset matching charging scheme according to the estimated charging state and charge according to the preset matching charging scheme, so that each sub-battery can be charged evenly, and the charging is more reasonable and effective.

[0128] According to the embodiment of the present invention, the obtaining of the user feature data, generating a user consumption feature portrait according to the user feature data, and extracting user consumption intention data according to the user consumption feature portrait specifically include:

[0129] Obtain the planned charging duration data of the zinc-nickel battery and the battery performance data of each sub-battery;

[0130] The battery performance data includes sub-battery standard capacity data, sub-battery remaining life ratio data, sub-battery remaining power data, and sub-battery charging efficiency data.

[0131] It should be noted that the planned charging duration data of the zinc-nickel battery refers to the approximate planned charging time determined by the user based on their time plan or itinerary plan before charging, that is, the charging duration data is determined; the zinc-nickel battery is composed of multiple sub-batteries, and obtaining the battery performance data of the sub-batteries includes the standard capacity data of the sub-batteries, the remaining life ratio data of the sub-batteries, the remaining power data of the sub-batteries, and the charging efficiency data of the sub-batteries. The standard capacity data of the sub-batteries refers to the standard power capacity value of the sub-batteries. During the use of the sub-batteries, with the increase in the number of charge and discharge cycles and the influence of time factors, its capacity will gradually decrease. The remaining life ratio data of the sub-batteries refers to the ratio of the actual maximum capacity value of the sub-batteries to the standard capacity; the remaining power data of the sub-batteries refers to the remaining capacitance value in the sub-batteries.

[0132] According to an embodiment of the present invention, obtaining the charging power data of the zinc-nickel battery and processing it in combination with the battery performance data to obtain the estimated charging duration data of the zinc-nickel battery specifically includes:

[0133] Querying a preset battery charge and discharge performance database according to the remaining life ratio data of the sub-batteries to obtain a sub-battery charging duration correction index, and calculating an effective charging duration correction index of the zinc-nickel battery according to the sub-battery charging duration correction index;

[0134] Taking the average value of the charging efficiency data of the sub-batteries to obtain effective charging efficiency data;

[0135] Obtaining the charging power data of the zinc-nickel battery, and multiplying the charging power data by the effective charging efficiency data to obtain effective charging power data;

[0136] Inputting the battery standard capacity data, the remaining life ratio data of the sub-batteries, the remaining power data of the sub-batteries, the effective charging power data, and the effective charging duration correction index into a preset zinc-nickel battery charging duration estimation model for processing to obtain estimated duration data;

[0137] The calculation formula for the estimated duration data in the zinc-nickel battery charging duration estimation model is:

[0138]

[0139] Wherein, Y s is the estimated duration data, Y x is the effective charging duration correction index, Y g is the effective charging power data, D bi 、S si 、S diThey are respectively the battery standard capacity data, the remaining life ratio data of the sub-battery, and the remaining power data of the sub-battery. n is the number of sub-batteries in the preset zinc-nickel battery, and α is the preset characteristic coefficient (the characteristic coefficient is obtained by querying the charge-discharge platform of the preset zinc-nickel battery).

[0140] It should be noted that to obtain the charging power data of the zinc-nickel battery, the charging power refers to the average charging power at the battery terminal when the power source charges the battery; after the remaining life ratio data of the sub-battery is determined, the charging duration correction index of the sub-battery is obtained by querying the preset battery charge-discharge performance database. The battery charge-discharge performance database is preset and is obtained through training and calculation of a large amount of historical data. The battery charge-discharge performance database contains the remaining life ratio data of the sub-battery and the corresponding charging duration correction index of the sub-battery. The charging duration correction index of the sub-battery refers to the index that affects the time required for the sub-battery to be fully charged due to its own performance changes. After adding up the charging duration correction indexes of each sub-battery and taking the average value, the effective charging duration correction index is obtained; when charging the zinc-nickel battery, due to the inconsistent performance states of each sub-battery, after the input charging power is determined, the sub-battery charging efficiency data will also be different. The sub-battery charging efficiency data refers to the ratio data of the charging input power converted into the battery power growth power when charging the sub-battery; the charging power data refers to the power data directly input to the battery by the power source through the power charging device. During the charging process, the charging power data will change due to different battery conditions. Therefore, after taking the average value, it is recorded as the effective charging power data, and the effective charging power data can better reflect the charging power data of the zinc-nickel battery; the estimated duration data is an evaluation data of the time required for the current battery to be charged from the remaining power to the full charge; the zinc-nickel battery charging duration estimation model is obtained through training with a large amount of historical data, and the estimated duration data can be calculated through this model.

[0141] According to the embodiment of the present invention, obtaining the charging duration relative index by comparing the estimated duration data with the planned charging duration data, and comparing the charging duration relative index with the preset charging duration relative index threshold to obtain the estimated charging state specifically includes:[[]]

[0142] Obtaining the charging duration relative index by dividing the estimated duration data by the planned charging duration data;

[0143] Comparing the charging duration relative index with the preset charging duration relative index threshold to obtain the estimated charging state, including the full state or the not full state;

[0144] If the charging duration relative index is greater than or equal to the preset charging duration relative index threshold, the estimated charging state is the fully chargeable state;

[0145] If the relative charging duration index is less than the preset relative charging duration index threshold, the estimated charging state is the non - full - charge state.

[0146] It should be noted that, for a more intuitive comparison of the estimated duration data and the planned charging duration data, the relative charging duration index is obtained by dividing the two. After comparing the relative charging duration index with the threshold, the estimated charging state is obtained. In this embodiment, the relative charging duration index threshold is set to (0, 1) for the non - full - charge state; when it is greater than or equal to 1, it is the full - charge state. That is, when the relative charging duration index is greater than or equal to the preset relative charging duration index threshold, it means that the planned charging duration is greater than or equal to the estimated duration data, and the zinc - nickel battery can be fully charged; when the relative charging duration index is less than the preset relative charging duration index threshold, it means that the planned charging duration is less than the estimated duration data, and the zinc - nickel battery cannot be fully charged in this charging.

[0147] According to the embodiment of the present invention, judging the estimated charging state and obtaining the corresponding matching charging scheme, and charging the zinc - nickel battery according to the matching charging scheme specifically includes:

[0148] If the estimated charging state is the full - charge state, the zinc - nickel battery is charged in sequence according to the circuit connection order of the sub - batteries.

[0149] If the estimated charging state is the non - full - charge state, the zinc - nickel battery is charged according to the dynamic evaluation mode.

[0150] It should be noted that when the zinc - nickel battery can be fully charged, each sub - battery can reach the best charging effect, so it can be charged in sequence according to the circuit connection order of the sub - batteries in the zinc - nickel battery; when the estimated charging state is the non - full - charge state, it means that all sub - batteries cannot be fully charged. In order to enable each sub - battery to be better charged, a dynamic evaluation will be carried out before each charging in combination with the situation of the sub - batteries, and an optimal distribution of the charging amount will be carried out. When the battery capacity permits, each battery will have equal power after charging.

[0151] According to the embodiment of the present invention, the dynamic evaluation mode specifically includes:

[0152] Calculating the remaining total power data of the zinc - nickel battery according to the remaining power data of the sub - batteries and the preset number of sub - batteries;

[0153] Calculating the real - time capacity data of the zinc - nickel battery according to the standard capacity data of the sub - batteries, the remaining life ratio data of the sub - batteries and the preset number of sub - batteries;

[0154] Calculating the estimated power ratio data according to the charging power data, the planned charging duration data, the remaining total power data and the real - time capacity data;

[0155] Compare the estimated power proportion data with the remaining life proportion data of the sub-batteries through a threshold;

[0156] If the remaining life proportion data of all the sub-batteries are greater than the estimated power proportion data, the zinc-nickel battery will charge the power proportion data of the sub-batteries to the estimated power proportion data in sequence according to the circuit connection order of the sub-batteries;

[0157] If some of the remaining life proportion data of the sub-batteries are less than or equal to the estimated power proportion data, they are recorded as priority charge sub-batteries, and the priority charge sub-batteries are fully charged in ascending order of the remaining life proportion data, and the remaining sub-batteries are re-allocated according to a preset method.

[0158] It should be noted that the number of sub-batteries in the zinc-nickel battery is preset according to user requirements. Therefore, the total remaining power data of the zinc-nickel battery is obtained by adding the remaining power data of each sub-battery;

[0159] The real-time capacity data of the zinc-nickel battery is calculated based on the standard capacity data of the sub-batteries, the remaining life proportion data of the sub-batteries and the preset number of sub-batteries. The calculation formula is:

[0160]

[0161] Among them, S r is the real-time capacity data, D bi 、S siThey are respectively the battery standard capacity data and the remaining life ratio data of the i-th sub-battery, and n is the number of sub-batteries in the preset zinc-nickel battery; since the capacity of the battery changes over time, the real-time capacity data refers to the latest capacity data of the zinc-nickel battery at present; multiplying the charging power data by the planned charging duration data to obtain the charging amount data, adding the charging amount data to the remaining total power data to obtain the estimated total power data of the zinc-nickel battery after charging, and dividing the estimated total power data by the real-time capacity data to obtain the estimated power ratio data; comparing the estimated power ratio data with the remaining life ratio data of the sub-battery through a threshold. If the remaining life ratio data of each sub-battery is greater than the estimated power ratio data, it means that each sub-battery cannot be fully charged during this charging, and then charging is carried out in sequence according to the circuit connection order of the sub-batteries, and the power ratio data of each sub-battery is charged to the estimated power ratio data to ensure the consistency of sub-battery charging; if the remaining life ratio data of some sub-batteries is less than or equal to the estimated power ratio data, it means that this part of the batteries can be fully charged and is recorded as the priority charge sub-batteries, and the remaining sub-batteries are the remaining sub-batteries. First, charge the priority charge sub-batteries, and then count the priority charging amount of the priority charge sub-batteries. Subtracting the priority charging amount from the charging amount data to obtain the charge amount to be allocated. Adding the charge amount to be allocated to the remaining power data of the remaining sub-batteries to obtain the total estimated reachable power of the remaining sub-batteries. Dividing the total estimated reachable power by the number of remaining sub-batteries to obtain the reachable power of the sub-battery, and the remaining sub-batteries are charged to the reachable power of the battery according to the connection order of the sub-batteries.

[0162] According to an embodiment of the present invention, it further includes:

[0163] Multiplying the sub-battery standard capacity data by the remaining life ratio data of the sub-battery to obtain the actual capacity data of the sub-battery;

[0164] Dividing the remaining power data of the sub-battery by the actual capacity data of the sub-battery to obtain the real-time remaining power ratio data of each sub-battery;

[0165] After sorting the real-time remaining power ratio data in descending order, the previous real-time remaining power ratio data and the minimum real-time remaining power ratio data are obtained;

[0166] Subtracting the minimum real-time remaining power ratio data from the previous real-time remaining power ratio data respectively to obtain the real-time remaining power ratio difference data of each sub-battery;

[0167] Comparing the real-time remaining power ratio difference data with a preset real-time remaining power ratio difference threshold to obtain the discharge amount difference state;

[0168] If the real-time remaining power ratio difference data is less than the preset real-time remaining power ratio difference threshold, the discharge amount difference state is the normal state, and the preset equal-ratio discharge mode is correspondingly started;

[0169] If the real-time remaining power ratio difference data is greater than or equal to the preset real-time remaining power ratio difference threshold, the discharge amount difference state is an abnormal state, and the preset sequential discharge mode is correspondingly started.

[0170] It should be noted that the capacity of the zinc-nickel battery will change during use. Therefore, during use, the actual capacity shall prevail, and the actual capacity data of the sub-battery needs to be obtained; when discharging the zinc-nickel battery, in order to extend the service life of the battery, balanced discharge shall be carried out, and no single sub-battery shall be over-discharged. The balanced discharge only requires that the difference in the remaining power ratio data between the sub-batteries shall not be greater than the preset value; in order to achieve the balanced discharge of each sub-battery, the real-time remaining power ratio data will be sorted and compared to judge; the previous real-time remaining power ratio data refers to the real-time remaining power ratio data except the minimum real-time remaining power ratio data in the sorted real-time remaining power ratio data; the real-time remaining power ratio difference data is obtained by successively subtracting the minimum real-time remaining power ratio data from the previous real-time remaining power ratio data, and then the discharge amount difference state is obtained by successively comparing with the preset real-time remaining power ratio difference threshold; if the real-time remaining power ratio difference data is less than the preset real-time remaining power ratio difference threshold, it indicates that the discharge between the sub-batteries is balanced, which is a normal state, and the preset equal-ratio discharge mode is correspondingly started; if the real-time remaining power ratio difference data is greater than or equal to the preset real-time remaining power ratio difference threshold, it indicates that the discharge between the sub-batteries is unbalanced, and it needs to be executed according to the preset sequential discharge mode. In this actual example, the real-time remaining power ratio difference threshold is set to 0.15.

[0171] It is worth mentioning that the equal-ratio discharge mode specifically includes:

[0172] Obtain the estimated power consumption data;

[0173] Calculate the power ratio data of each sub-battery according to the remaining power data of the sub-battery;

[0174] Multiply the power ratio data of each sub-battery by the estimated power consumption data to obtain the discharge amount data of each sub-battery;

[0175] Each sub-battery discharges according to the discharge amount data in the preset connection order of the sub-batteries in the battery.

[0176] It should be noted that before obtaining the estimated power consumption data and executing the equal - ratio discharge mode, the magnitudes of the estimated power consumption data and the remaining battery power data are judged, and the estimated power consumption data should be less than the remaining battery power data; the remaining battery power data refers to the sum of the remaining power data of the sub - batteries; the power ratio data of each sub - battery is calculated based on the remaining power data of the sub - batteries. The calculation method is as follows: divide the remaining power data of the sub - battery by the remaining battery power data, and then multiply the power ratio data by the estimated power consumption data to obtain the discharge amount data of each sub - battery. Each sub - battery discharges according to the corresponding discharge amount data.

[0177] It is worth mentioning that the sequential discharge mode specifically includes:

[0178] Compare the real - time remaining power ratio difference data with the preset real - time remaining power ratio difference threshold to obtain the priority discharge sub - battery;

[0179] If the real - time remaining power ratio difference data is greater than the preset real - time remaining power ratio difference threshold, the corresponding sub - battery is the priority discharge sub - battery;

[0180] If the real - time remaining power ratio difference data is less than or equal to the preset real - time remaining power ratio difference threshold, the corresponding sub - battery is the equal - ratio discharge sub - battery;

[0181] Multiply the real - time remaining power ratio difference data corresponding to the priority discharge sub - battery by the remaining power data of the sub - battery to obtain the priority discharge amount data;

[0182] After the priority discharge sub - battery discharges preferentially according to the priority discharge amount data, the remaining estimated power consumption data is obtained;

[0183] Then the priority discharge sub - battery and the equal - ratio discharge sub - batteries perform equal - ratio discharge according to the remaining estimated power consumption data.

[0184] It should be noted that when the real - time remaining power ratio difference data is greater than the preset real - time remaining power ratio difference threshold, it indicates that the discharge is unbalanced. Mark the sub - battery with more remaining power corresponding to the remaining power ratio difference data in this case as the priority discharge sub - battery, which discharges preferentially during discharge. The calculation method of the priority discharge amount is: multiply the real - time remaining power ratio difference data by the remaining power data of the sub - battery; after the priority discharge sub - battery discharges, subtract the priority discharge amount from the estimated power consumption data to obtain the remaining estimated power consumption data, and then the priority discharge sub - battery after priority discharge and the equal - ratio discharge sub - batteries perform equal - ratio discharge together.

After threshold comparison, the estimated charging state is obtained, and the matching charging scheme is obtained according to the estimated charging state. The real-time remaining power ratio difference data is calculated according to the battery performance data, and the discharge amount difference state, that is, the corresponding discharge mode, is obtained after threshold comparison; thus, through the calculation and threshold comparison of the estimated duration data, the charging duration relative index and the real-time remaining power ratio difference data, the intelligent charging and discharging of the zinc-nickel battery is realized.
