Description

Technical Field

[0001] The present application relates to the technical field of marine battery management, and in particular to a method, device and storage medium for monitoring and managing a marine battery system. Background Art

[0002] At present, most conventional commercial ships use heavy oil as fuel, and most of the power sources of the ship's power system also come from the combustion of heavy oil. However, the heating and combustion of heavy oil will produce pollutant substances such as aromatic ring chemical substances and carbon dioxide, which will cause great harm to the environment and the human body. And heavy oil is relatively viscous and has the property of being difficult to volatilize. Once the heavy oil in the ship leaks, it will cause great harm to the marine environment. Therefore, in order to save resources, protect the environment and promote sustainable development, more and more new energy ships have gradually appeared in our vision.

[0003] In existing new energy ships, most of them use storage batteries as power sources. In order to facilitate the management of the storage batteries, the storage batteries are usually divided into multiple battery clusters, and then multiple battery groups are divided in the multiple battery clusters. All battery groups are connected to the power system through a DC bus, and each battery group can meet the power supply requirements of the power system. During the operation of the ship, a single battery group is used for power supply. When the power of the power supply battery group is low, the operator manually switches to other battery groups to continue power supply, so as to ensure the continuous and stable operation of the new energy ship.

[0004] Regarding the above related technologies, the inventor believes that there are the following defects: the switching process of the battery group is manually operated, and the randomness is relatively large during manual switching, which easily leads to a higher usage frequency of some battery groups during the long-term use of the new energy ship. A higher usage frequency of the battery group will easily lead to a reduction in the service life of the battery group, and ultimately lead to uneven service lives of each battery group, and it is necessary to frequently replace the battery groups in the battery system. Summary of the Invention

[0005] In order to improve the defect that the existing battery group switching method easily leads to uneven service lives of the battery groups in the battery system, and thus it is necessary to frequently replace the battery groups, the present application provides a method, device and storage medium for monitoring and managing a marine battery system.

[0006] In a first aspect, the present application provides a method for monitoring and managing a marine battery system, including the following steps:

[0007] When each battery group in the battery system is fully charged, obtain the battery group information of all the battery groups;

[0008] Based on the battery group information, configure a power supply sequence for each of the battery groups;

[0009] Supply power using each of the battery packs in sequence according to the power supply sequence, and record the power supply data of each battery pack during power supply;

[0010] After all the battery packs have been powered once, adjust the power supply sequence based on the power supply data;

[0011] Supply power using each of the battery packs in sequence according to the adjusted power supply sequence.

[0012] By adopting the above technical solution, it is possible to obtain the battery pack information of all battery packs after all the battery packs in the battery system are fully charged. Through the analysis of the battery pack information, the service life of each battery pack can be preliminarily judged. Thus, the power supply sequence of the battery packs in the battery system can be configured according to the order from the longest to the shortest service life. After using each battery pack to supply power once in sequence according to the power supply sequence, the service life of the battery packs can be further analyzed based on the power supply data during battery pack power supply, and the power supply sequence of all battery packs during the next power supply of the battery system can be adjusted according to the analysis result. Since all the battery packs will not be depleted of power every time during ship navigation, the battery packs with longer service life are placed at the front of the power supply sequence, and the battery packs with shorter service life are placed at the back of the power supply sequence. Therefore, the overall service life of the battery packs can be balanced during the long-term use of the ship, and the number of times of replacing a single battery pack in the battery system due to life reasons can be reduced.

[0013] Optionally, configuring the power supply sequence for each battery pack based on the battery pack information includes the following steps: uniformly quantifying various data information in the battery pack information into benchmark rating parameters;

[0014] Configuring parameter weight values based on the benchmark rating parameters;

[0015] Calculating the status scores of each battery pack by combining the benchmark rating parameters and the parameter weight values;

[0016] Sort each battery pack in ascending order according to the status score, and configure the power supply sequence of each battery pack according to the sorting result.

[0017] By adopting the above technical solution, various data with different dimensions in the battery information group are uniformly quantified into benchmark rating parameters with the same value range, and then parameter weight values are configured according to the influence degree of the benchmark rating parameters. Finally, the status scores of the corresponding battery packs are calculated by combining the benchmark rating parameters corresponding to each data information and the parameter weight values. The service life of the battery packs can be preliminarily judged through the status scores. The lower the status score, the longer the service life. Therefore, each battery pack can be sorted in ascending order according to the status score, and the power supply sequence of each battery pack can be configured according to the sorting result.

[0018] Optionally, the step of uniformly quantifying various data information in the battery pack information into a reference rating parameter includes the following steps:

[0019] Obtain the data range of each type of data information in the battery pack information;

[0020] Based on the preset number of partitions, divide the data range into multiple rating areas, and each rating area corresponds to a rating parameter; according to the rating parameter corresponding to the rating area where the data information is located, determine the reference rating parameter of each data information.

[0021] By adopting the above technical solution, first obtain the data range of various types of data information in the battery pack information, and then divide the data range into multiple rating areas according to the preset number of partitions, and each rating area corresponds to a rating parameter. Therefore, through the division of the rating areas, the value range of all data information is unified into the value range of the rating parameters. Then, according to the rating area where the data information is located (i.e., the corresponding data interval in the data range), determine the reference rating parameter of the data information, thereby completing the unified quantification of various types of data information.

[0022] Optionally, the step of configuring a parameter weight value based on the reference rating parameter includes the following steps:

[0023] Judge whether the reference rating parameter exceeds the preset rating parameter threshold;

[0024] If the reference rating parameter does not exceed the rating parameter threshold, configure a first parameter weight value for the reference rating parameter; if the reference rating parameter exceeds the rating parameter threshold, configure a second parameter weight value for the reference rating parameter based on the preset proportional relationship, and the second parameter weight value is greater than the first parameter weight value.

[0025] By adopting the above technical solution, the reference rating parameter is divided into a reference rating parameter with a smaller influence degree on the service life and a reference rating parameter with a larger influence degree through the preset rating parameter threshold. For the reference rating parameter with a smaller influence degree on the service life, a first parameter weight value with a smaller value is configured, while for the reference rating parameter with a larger influence degree on the service life, a second parameter weight value is configured according to the preset proportional relationship, and the larger the reference rating parameter, the larger the configured second parameter weight value.

[0026] Optionally, the calculation formula for the battery pack state score is as follows:

[0027]

[0028] In the formula, Q is the state score, n is the number of types of data information included in the battery pack information, Ri is the reference rating parameter for the i-th type of data information, K i is the parameter weight value corresponding to the reference rating parameter for the i-th type of data information.

[0029] By adopting the above technical solution, multiplying the reference rating parameter corresponding to each data information by the configured parameter weight value, and then adding up the product results corresponding to all data information, the status score of the corresponding battery pack can be obtained.

[0030] Optionally, the battery pack information includes the total capacity of the battery pack, the cumulative usage time of the battery pack, and the charging power of the battery pack. The charging power of the battery pack is the average charging power during the process of charging the battery pack from the start of charging to full charge.

[0031] By adopting the above technical solution, the total capacity of the battery pack, the cumulative usage time of the battery pack, and the charging power of the battery pack can be obtained through the charging process or through pre-stored data. Based on the data information in the three dimensions of the total capacity of the battery pack, the cumulative usage time of the battery pack, and the charging power of the battery pack, the service life of the battery pack can be initially analyzed.

[0032] Optionally, the power supply data includes the discharge capacity and the average temperature during power supply. The adjustment of the power supply order based on the power supply data includes the following steps:

[0033] Form a battery pack sequence based on the power supply order;

[0034] Traverse the power supply data of all the battery packs based on the battery pack sequence, and determine whether the average temperature exceeds a preset temperature threshold;

[0035] If the average temperature exceeds the temperature threshold, adjust the corresponding battery pack to the end of the battery pack sequence;

[0036] If the average temperature does not exceed the temperature threshold, determine whether the discharge capacity is lower than a preset capacity threshold;

[0037] If the discharge capacity is not lower than the capacity threshold, do not adjust the power supply order of the corresponding battery pack;

[0038] If the discharge capacity is lower than the capacity threshold, adjust the corresponding battery pack to the last 50% of the battery pack sequence;

[0039] Adjust the power supply order correspondingly according to the adjusted battery pack sequence.

[0040] By adopting the above technical solution, the service life of the battery pack can also be analyzed based on the power supply data of the battery pack. Therefore, the analysis result of the service life can be obtained by combining the discharge capacity of the battery pack and the average temperature during power supply, and the power supply order of the battery pack can be adjusted according to the final analysis result, so as to adjust the battery pack with a shorter service life to the rear position of the power supply order, thereby minimizing the number of times the battery pack with a shorter service life is used as much as possible.

[0041] In a second aspect, the present application further provides a computer system, including a processor and a memory. When the processor runs the computer instructions stored in the memory, it executes the method described in the first aspect.

[0042] By adopting the above technical solution, the battery pack information of all battery packs can be obtained after all battery packs in the battery system are fully charged. By analyzing the battery pack information, the service life of each battery pack can be preliminarily judged. Thus, the power supply order of the battery packs in the battery system can be configured according to the order of the service life from long to short. After each battery pack is used for power supply once in sequence according to the power supply order, the service life of the battery pack can be further analyzed based on the power supply data during the power supply of the battery pack, and the power supply order of all battery packs during the next power supply of the battery system can be adjusted according to the analysis result. Since all the battery packs will not be depleted of power every time during ship navigation, the battery packs with a longer service life are placed in the front position of the power supply order, and the battery packs with a shorter service life are placed in the rear position of the power supply order. Therefore, the overall service life of the battery packs can be balanced during the long-term use of the ship, and the number of times of replacing a single battery pack in the battery system due to life reasons can be reduced.

[0043] In a third aspect, the present application further provides a readable storage medium, which includes instructions. When the instructions run on a computer, the computer is made to execute the method described in the first aspect.

[0044] By adopting the above technical solution, the battery pack information of all battery packs can be obtained after all battery packs in the battery system are fully charged. By analyzing the battery pack information, the service life of each battery pack can be preliminarily judged. Thus, the power supply order of the battery packs in the battery system can be configured according to the order of the service life from long to short. After each battery pack is used for power supply once in sequence according to the power supply order, the service life of the battery pack can be further analyzed based on the power supply data during the power supply of the battery pack, and the power supply order of all battery packs during the next power supply of the battery system can be adjusted according to the analysis result. Since all the battery packs will not be depleted of power every time during ship navigation, the battery packs with a longer service life are placed in the front position of the power supply order, and the battery packs with a shorter service life are placed in the rear position of the power supply order. Therefore, the overall service life of the battery packs can be balanced during the long-term use of the ship, and the number of times of replacing a single battery pack in the battery system due to life reasons can be reduced.

[0045] In summary, the present application includes the following beneficial technical effects:

[0046] After all battery packs in the battery system are fully charged, the battery pack information of all battery packs can be obtained. By analyzing the battery pack information, the service life of each battery pack can be initially judged. Thus, the power supply order of the battery packs in the battery system can be configured according to the order from the longest to the shortest service life. After each battery pack is used for power supply once in sequence according to the power supply order, the service life of the battery pack can be further analyzed based on the power supply data during the power supply of the battery pack, and the power supply order of all battery packs during the next power supply of the battery system can be adjusted according to the analysis result. Since all the battery packs are not consumed every time during ship navigation, the battery packs with longer service life are placed at the forefront of the power supply order, and the battery packs with shorter service life are placed at the rear of the power supply order. Therefore, the overall service life of the battery packs can be balanced during the long-term use of the ship, and the number of times of replacing a single battery pack in the battery system due to life reasons can be reduced.

[0052] The following further elaborates on the present application in conjunction with the attached Figures 1 to 5 for a more detailed description.

[0053] An embodiment of the present application discloses a monitoring and management method for a marine battery system.

[0054] Referring to Figure 1 , the monitoring and management method for a marine battery system includes the following steps:

[0055] S101. When each battery pack in the battery system is fully charged, obtain the battery pack information of all battery packs.

[0056] Among them, each battery pack in the battery system has a unique battery pack number. To facilitate the analysis of the state of the battery system, some information of each battery pack in the battery system and its battery pack number can be stored in a preset battery system database. The battery pack information includes the total battery pack capacity, the cumulative usage time of the battery pack, and the charging power of the battery pack. The charging power of the battery pack is the average charging power during the process of charging the battery pack from the start of charging to full charge. The charging power of the battery pack can be statistically calculated during the charging process of the battery pack, while the total battery pack capacity and the cumulative usage time of the battery pack need to be retrieved from the battery system database according to the battery pack number.

[0057] The total battery pack capacity is the actual capacity of the battery pack. The total battery pack capacity of the battery pack is detected by manual detection at regular intervals, and the battery system database is updated according to the detection results. The cumulative usage time of the battery pack is the cumulative discharge time of the battery pack. A timer can be configured in the discharge circuit of the battery pack. When the battery pack is in the discharge state, the timer starts to record the discharge time. When the battery pack ends this discharge state, the timer ends the time recording and uploads the recorded time to the battery system database. The battery system database will accumulate and calculate the time recorded each time according to a preset accumulation algorithm and save it. The saved time is the cumulative discharge time of the battery pack.

[0058] S102. Configure the power supply sequence for each battery pack based on the battery pack information.

[0059] Among them, the state and service life of the battery pack can be analyzed through each data information in the battery pack information, and all battery packs are rated and sorted according to the service life according to the analysis results. Finally, the power supply sequence of the battery packs is configured according to the sorting results, so that the battery packs with longer service life are preferentially used for power supply.

[0060] S103. Use each battery pack for power supply in sequence according to the power supply sequence, and record the power supply data of each battery pack during power supply.

[0061] Among them, different numbers are sequentially marked for each battery pack according to the power supply sequence, and the battery pack at the first position in the sequence is marked as the reference battery pack. Each battery pack is used for power supply in sequence starting from the reference battery pack. When the battery pack starts to supply power, the power supply data of the battery pack is recorded, and the remaining power of the battery pack is monitored in real time. When the remaining power of the battery pack is lower than the preset power threshold, it automatically switches to the next battery pack according to the power supply sequence. After switching to the next battery pack, the power supply data and number of the previous battery pack are automatically uploaded to the preset battery system database and temporarily stored in the temporary storage area of the battery system database.

[0062] S104. After all battery packs have been powered once, adjust the power supply sequence based on the power supply data.

[0063] Among them, the switching of the battery packs will be cycled infinitely according to the power supply sequence. When the battery pack being powered is the last battery pack in the power supply sequence and the remaining power is lower than the power threshold, it will switch to the battery pack at the beginning of the power supply sequence. Therefore, each time the battery pack is switched, it is necessary to identify whether the switched battery pack is the reference battery pack. If it is the reference battery pack, it means that all battery packs have been powered once. At this time, the power supply data of all battery packs during the power supply process can be retrieved from the temporary storage area in the battery system database, and the power supply data is analyzed to obtain an analysis result, and then the power supply sequence for the next power supply is adjusted according to the analysis result.

[0064] S105. Power each battery pack in turn according to the adjusted power supply sequence.

[0065] The implementation principle of this embodiment is as follows:

[0066] After all battery packs in the battery system are fully charged, the battery pack information of all battery packs can be obtained. By analyzing the battery pack information, the service life of each battery pack can be initially judged. Therefore, the power supply sequence of the battery packs in the battery system can be configured according to the order from long to short service life. After each battery pack is powered once according to the power supply sequence, the service life of the battery pack can be further analyzed based on the power supply data during the power supply of the battery pack, and the power supply sequence of all battery packs during the next power supply of the battery system can be adjusted according to the analysis result. Since all battery packs will not be consumed every time during ship navigation, the battery packs with longer service life are placed in the front of the power supply sequence, and the battery packs with shorter service life are placed in the back of the power supply sequence. Thus, the overall service life of the battery packs can be balanced during the long-term use of the ship, and the number of times of replacing a single battery pack in the battery system due to life reasons can be reduced.

[0067] In one implementation manner of the embodiment of the present application, with reference to Figure 2 , step S102 specifically includes the following steps: S201. Uniformly quantify various data information in the battery pack information into reference rating parameters.

[0068] Among them, since the battery pack information of the battery pack includes multi-dimensional data information such as the total capacity of the battery pack, the cumulative usage time of the battery pack, and the charging power of the battery pack, and the value ranges of each type of data information are different, before calculating the battery pack status score according to the overall battery pack information, all types of data information can be uniformly quantified into reference rating parameters with the same value range. The reference rating parameter can reflect the value position of the data information within its original value range, which is a manifestation of the numerical degree, and the trend of the numerical degree change of each type of data information is the same.

[0069] S202. Configure parameter weight values based on the benchmark rating parameters.

[0070] Among them, before calculating the state score, it is also necessary to configure parameter weight values for each benchmark rating parameter. The greater the numerical degree reflected by the benchmark rating parameter, the greater the impact on the state of the battery pack. Therefore, the configured parameter weight value is also greater.

[0071] S203. Calculate the state scores of each battery pack by combining the benchmark rating parameters and the parameter weight values.

[0072] Among them, the calculation formula for the battery pack state score is as follows:

[0073]

[0074] In the formula, Q is the state score, n is the number of types of data information included in the battery pack information, R i is the benchmark rating parameter of the i-th type of data information, K i is the parameter weight value corresponding to the benchmark rating parameter of the i-th type of data information.

[0075] S204. Sort each battery pack in ascending order according to the state score, and configure the power supply order of each battery pack according to the sorting result.

[0076] Among them, since the calculation of the state score depends on multi-dimensional factors such as the total capacity of the battery pack, the cumulative usage time of the battery pack, and the charging power of the battery pack, and the smaller the benchmark rating parameter of each dimension, the lower the calculated state score. And the lower the state score, the longer the service life of the battery pack. Therefore, finally, each battery pack can be sorted in ascending order according to the state score, and the power supply order of each battery pack can be configured according to the sorting result.

[0077] The implementation principle of this embodiment is:

[0078] Unify and quantify various data of different dimensions in the battery information group into benchmark rating parameters with the same value range, then configure parameter weight values according to the influence degree of the benchmark rating parameters, and finally calculate the state score of the corresponding battery pack by combining the benchmark rating parameters and the parameter weight values corresponding to each data information. Through the state score, the service life of the battery pack can be initially judged. The lower the state score, the longer the service life. Therefore, each battery pack can be sorted in ascending order according to the state score, and the power supply order of each battery pack can be configured according to the sorting result.

[0079] In one implementation manner of the embodiment of the present application, referring to Figure 3 , step S201 specifically includes the following steps:

[0080] S301. Obtain the data range of each type of data information in the battery pack information.

[0081] Among them, the data range of various types of data information can be obtained based on the model of the storage battery in the battery pack and the type of data information through Internet retrieval, or the data range can be obtained by analyzing the historical data in the battery system database through big data. For example, the value range of the total battery pack capacity is 0% to 100%, and the value range of the cumulative battery pack usage time can be 0h to 500h.

[0082] S302. Divide the data range into multiple rating areas based on the preset number of partitions.

[0083] Among them, for example, assuming that the value range of the cumulative battery pack usage time is 0h to 500h and the preset number of partitions is 5, then according to the number of partitions, the value range of the cumulative battery pack usage time can be evenly divided into five rating areas: 0h to 100h, 100h to 200h, 200h to 300h, 300h to 400h, and 400h to 500h. Each rating area corresponds to a rating parameter. All rating parameters are natural numbers greater than 0 and the values of the rating parameters increase. The 5 rating areas can respectively represent rating parameters 1 to 5. Since the longer the cumulative battery pack usage time, the shorter the service life of the battery pack, the rating areas can be corresponded to the rating parameters in ascending order of the rating parameters, that is, the rating area of 0h to 100h corresponds to rating parameter 1, the rating area of 100h to 200h corresponds to rating parameter 2, and so on.

[0084] S303. Determine the reference rating parameter of each data information according to the rating parameter corresponding to the rating area where the data information is located.

[0085] Among them, based on the example described in detail in step S302, assuming that the cumulative battery pack usage time of the target battery pack is 146h, then the reference rating parameter of the target battery pack in the dimension of the cumulative battery pack usage time data information is 2.

[0086] The implementation principle of this embodiment is:

[0087] First, obtain the data range of various types of data information in the battery pack information, then divide the data range into multiple rating areas according to the preset number of partitions, and each rating area corresponds to a rating parameter. Therefore, through the division of the rating areas, the value range of all data information is unified into the value range of the rating parameters. Then, according to the rating area where the data information is located (that is, the corresponding data interval in the data range), the reference rating parameter of the data information is determined, so as to complete the unified quantification of various types of data information.

[0088] In one implementation manner of the embodiment of the present application, with reference toFigure 4 , step S202 specifically includes the following steps:

[0089] S401. Determine whether the reference rating parameter exceeds the preset rating parameter threshold. If the reference rating parameter does not exceed the rating parameter threshold, execute step S402; if the reference rating parameter exceeds the rating parameter threshold, execute step S403.

[0090] Among them, through big data analysis of the historical data in the battery system database, the target value range of each data information can be analyzed. The data information before the target value range has a relatively small impact on the service life of the battery pack, while the data information after the target value range has a relatively large impact on the service life of the battery pack. Then, the rating parameter threshold is determined according to the position of the target value range within the value range.

[0091] S402. Configure a first parameter weight value for the reference rating parameter.

[0092] Among them, since the reference rating parameter is lower than the rating parameter threshold, the impact of this reference rating parameter on the service life of the battery pack is relatively small, and the configured parameter weight value will be a relatively small first parameter weight value.

[0093] S403. Configure a second parameter weight value for the reference rating parameter based on a preset proportional relationship.

[0094] Among them, when the reference rating parameter exceeds the preset rating parameter threshold, each reference rating parameter corresponds to a second parameter weight value. All second parameter weight values are greater than the first parameter weight value, and the second parameter weight value has a preset proportional relationship with the reference rating parameter, that is, the larger the reference rating parameter, the greater the impact on the service life of the battery pack, and the larger the configured second parameter weight value.

[0095] The implementation principle of this embodiment is as follows:

[0096] The reference rating parameter is divided into a reference rating parameter with a relatively small impact on the service life and a reference rating parameter with a relatively large impact through the preset rating parameter threshold. For the reference rating parameter with a relatively small impact on the service life, a relatively small first parameter weight value is configured, while for the reference rating parameter with a relatively large impact on the service life, a second parameter weight value is configured according to the preset proportional relationship, and the larger the reference rating parameter, the larger the configured second parameter weight value.

[0097] In one implementation manner of the embodiment of the present application, the power supply data includes the discharge capacity and the average temperature during power supply. Referring to Figure 5 , step S104 specifically includes the following steps:

[0098] S501. Form a battery pack sequence based on the power supply order.

[0099] Among them, different numbers are marked for all battery packs from small to large according to the power supply order, and then all battery packs are edited into a list according to all the numbers to form a battery pack sequence.

[0100] S502. Traverse the power supply data of all battery packs based on the battery pack sequence, and judge whether the average temperature exceeds a preset temperature threshold. If the average temperature exceeds the temperature threshold, execute step S504; if the average temperature does not exceed the temperature threshold, execute step S504.

[0101] S503. Adjust the corresponding battery pack to the end of the battery pack sequence.

[0102] Among them, when the average temperature of the battery pack during power supply exceeds the temperature threshold, it means that the internal resistance of the battery pack is large and the service life is very short. Therefore, it is necessary to adjust the battery pack to the end of the battery pack sequence to minimize the number of times the battery pack is used. If the corresponding battery pack is already at the end of the battery pack sequence, no adjustment is made to this battery pack.

[0103] S504. Judge whether the discharge capacity is lower than a preset capacity threshold. If the discharge capacity is not lower than the capacity threshold, execute step S505; if the discharge capacity is lower than the capacity threshold, execute step S506.

[0104] S505. Do not adjust the power supply order of the corresponding battery pack.

[0105] Among them, not adjusting the power supply order of the corresponding battery pack means not adjusting the position of the corresponding battery pack in the battery pack sequence.

[0106] S506. Adjust the corresponding battery pack to the last 50% of the battery pack sequence.

[0107] Among them, if the average temperature of the battery pack does not exceed the temperature threshold, but the discharge capacity is lower than the capacity threshold, it means that the service life of the battery pack is short. It is necessary to adjust the battery pack to the last 50% of the battery pack sequence to reduce the number of times the battery pack is used. The specific adjustment method can be to adjust the battery pack to the median of the last 50% of the battery pack sequence. If the corresponding battery pack is already in the last 50% of the battery pack sequence, the position of the battery pack in the battery pack sequence is not adjusted.

[0108] S507. Correspondingly adjust the power supply order according to the adjusted battery pack sequence.

[0109] The implementation principle of this embodiment is:

[0110] The service life of the battery pack can also be analyzed based on the power supply data of the battery pack. Therefore, the analysis result of the service life can be obtained by combining the discharge capacity of the battery pack and the average temperature during power supply, and the power supply sequence of the battery pack can be adjusted according to the final analysis result, so as to adjust the battery pack with a shorter service life to the back position of the power supply sequence, thereby minimizing the number of times the battery pack with a shorter service life is used as much as possible.

[0111] An embodiment of the present application also discloses a computer system, including a processor and a memory. When the processor runs the computer instructions stored in the memory, it executes as Figures 1 to 5 shown in

[0112] The implementation principle of this embodiment is:

[0113] Through the retrieval of the program, the battery pack information of all battery packs in the battery system can be obtained after all battery packs are fully charged. By analyzing the battery pack information, the service life of each battery pack can be initially judged, so that the power supply sequence of the battery packs in the battery system can be configured according to the order from long to short service life. After each battery pack is used for power supply once in sequence according to the power supply sequence, the service life of the battery pack can be further analyzed based on the power supply data during the battery pack power supply, and the power supply sequence of all battery packs during the next power supply of the battery system can be adjusted according to the analysis result. Since all the battery packs will not be discharged every time during ship navigation, the battery packs with a longer service life are placed in the front of the power supply sequence, and the battery packs with a shorter service life are placed in the back of the power supply sequence, so that the service life of the overall battery pack can be balanced during the long-term use of the ship, and the number of times of replacing a single battery pack in the battery system due to life reasons can be reduced.

[0115] The implementation principle of this embodiment is:

[0116] Through the retrieval of the program, the battery pack information of all battery packs can be obtained after all battery packs in the battery system are fully charged. By analyzing the battery pack information, the service life of each battery pack can be preliminarily judged. Thus, the power supply order of the battery packs in the battery system can be configured according to the order from long to short service life. After each battery pack is used for power supply once in sequence according to the power supply order, the service life of the battery packs can be further analyzed based on the power supply data during the power supply of the battery packs, and the power supply order of all battery packs during the next power supply of the battery system can be adjusted according to the analysis results. Since all the battery packs may not be fully discharged each time during ship navigation, the battery packs with longer service life are placed in the front of the power supply order, and the battery packs with shorter service life are placed in the back of the power supply order. Therefore, the service life of the overall battery packs can be balanced during the long-term use of the ship, and the number of times of replacing a single battery pack in the battery system due to life reasons can be reduced.

[0117] The above are all the preferred embodiments of this application, and the protection scope of this application is not limited accordingly. Therefore, all equivalent changes made according to the structure, shape, and principle of this application should be covered within the protection scope of this application.
