[0039] Today, the power management system of electric ships often adopts centralized control, which not only increases the complexity of the system and the risk of failure, but also limits the flexible use of battery packs. In addition, the working status, charging and battery replacement processes of battery packs often lack intelligent management, resulting in the need to improve the power supply reliability of electric ships, and the charging and battery replacement efficiency is low and prone to errors.

The electronic device 100 may also include Figure 1 More or fewer components as shown, or with Figure 1 Different configurations are shown. Figure 1 Each component shown in the figure can be implemented by hardware, software or a combination thereof.

[0052] Please refer to Figure 2 , which is a flow chart of a power supply control method for an electric ship provided by an embodiment of the present invention, and is applied to a power management system in a distributed power system, wherein the distributed power system also includes a plurality of battery packs for powering the electric ship. Figure 1 The electronic device 100, or when the electronic device 100 is a control device for executing data processing and issuing instructions in a power management system, the method can be executed by the electronic device 100, for example, by the processor 120 in the electronic device 100. The power supply control method for an electric ship includes S110, S120 and S130.

[0053] S110, obtaining the power consumption mode of the electric ship.

[0054] S120: Find a target allocation strategy that matches the power usage pattern from among various pre-stored power allocation strategies.

[0055] S130: Control the working state of each of the battery packs based on the target allocation strategy.

[0056] By adopting a distributed power system, the power consumption mode is divided, and the target allocation strategy corresponding to the power consumption mode of the electric ship is used to control the working state of each battery pack, thereby improving the flexibility of battery pack use and the reliability of power supply.

[0057] Distributed power systems can be flexibly selected. For example, an AC distributed power system can be selected. Another example is that in order to reduce power conversion links and improve energy efficiency, a DC distributed power system can be selected.

[0058] Through a distributed architecture, power management functions are dispersed to various areas, such as battery cabinets, which reduces system complexity and improves reliability and flexibility compared to centralized control.

[0059] There may be multiple power usage modes for an electric vessel, for example, normal navigation mode, berthing mode, unberthing mode, shore power mode, mooring mode, etc. In S110, the current power usage mode of the electric vessel may be determined in a variety of ways. For example, the power usage mode may be determined based on the operating status and position of the electric vessel. For another example, the power usage mode of an electric vessel may be determined based on sensors and monitoring systems. For another example, the power usage mode of an electric vessel may be determined based on operation records and logs. For another example, the power usage mode of an electric vessel may be determined based on a power management system (Power Management System, PMS). For another example, the power usage mode of an electric vessel may be determined in a combination of multiple ways to ensure the accuracy of the power usage mode determination.

[0060] In S120 and S130, in each power consumption mode, the corresponding allocation strategy can be flexibly set.

[0061] For example, see Figure 3 In order to ensure the reliability of power supply for electric ships and avoid stopping the electric ship due to exhaustion of battery packs, when the electric ship is in the navigation mode, the plurality of battery packs can be divided into a plurality of pairs, and a pair of battery packs is determined from the plurality of pairs of battery packs as the target pair of battery packs, and the target pair of battery packs is controlled to supply power to the main propulsion devices on both sides of the electric ship. The remaining power of the target pair of battery packs is higher than the preset power threshold.

[0062] The remaining power of the target pair of battery packs is obtained in real time, and it is determined whether the remaining power is lower than the preset power threshold. If so, the process returns to the step of determining a pair of battery packs from the plurality of pairs of battery packs as the target pair of battery packs to determining whether the remaining power is lower than the preset power threshold. If not, the current target pair of battery packs is continued to be used to power the main propulsion devices on both sides of the electric ship.

[0063] Furthermore, a battery group is determined as a backup battery group from the remaining battery groups except the target pair of battery groups among the plurality of battery groups, and the backup battery group is controlled to supply power to the AC distribution board of the electric ship. When the remaining power of the other pairs of battery groups except the backup battery group is lower than the preset power threshold, one of the battery groups with the remaining power lower than the preset power threshold is switched to supply power to the AC distribution board, and the battery group of the pair to which the backup battery group belongs is used as the target pair of battery groups.

[0064] For example, if 1-6# battery packs are included, 1-3# battery packs are located in the left DC switch cabinet (battery box cabinet), and 4-6# battery packs are located in the right DC switch cabinet, in the normal sailing mode of the electric ship, the left and right main propulsion devices serve as the power source of the electric ship, and the right daily inverter such as INV2 serves as the daily power source of the electric ship. When the electric ship sets out on a voyage, it is in the first stage.

[0065] In the first stage, battery packs 1-6# are all fully charged. Battery pack 1# supplies power to the left main propulsion unit, battery pack 6# supplies power to the right main propulsion unit, and battery pack 4# provides power to the AC distribution board through the right day inverter.

[0066] The remaining power (State Of Charge, SOC) of the 1# and 6# battery packs is continuously monitored. As the voyage progresses, when the SOC of the 1# and 6# battery packs drops to the preset power threshold, such as below 30%, the power supply of the left main propulsion device is switched from the 1# battery pack to the 2# battery pack, and the power supply of the right main propulsion device is switched from the 6# battery pack to the 5# battery pack. At the same time, the 4# battery pack still supplies power to the AC distribution board through the right day inverter. The electric ship enters the second stage.

[0067] The SOC of the 2# battery pack and the 5# battery pack was continuously monitored. When the SOC of the 2# battery pack and the 5# battery pack also dropped below 30%, the power supply of the left main propulsion unit was further switched to the 3# battery pack, and the power supply of the right main propulsion unit was switched to the 4# battery pack. At the same time, the power supply of the AC switchboard was also switched from the 4# battery pack to other battery packs with SOC below 30%, such as the 5# battery pack. The electric ship ended its voyage in the third phase.

[0068] For another example, when the power consumption mode is the unmooring mode, a pair of battery groups is determined from the multiple pairs of battery groups as the target pair of battery groups, and the target pair of battery groups is controlled to respectively supply power to the main propulsion devices on both sides of the electric ship, the right daily inverter is controlled as the daily power source of the electric ship, and the bow propulsion inverter is controlled as the power source for the bow propulsion of the electric ship. It can be understood that after the electric ship enters the normal sailing mode from the unmooring mode, when the SOC of the target pair of battery groups is not lower than the preset power threshold, the target pair of battery groups can continue to supply power to the main propulsion devices on both sides of the electric ship.

[0069] When the electric ship switches from the sailing mode to the berthing mode, the target pair of batteries in the sailing mode continues to be controlled to respectively power the main propulsion devices on both sides of the electric ship, the right daily inverter is controlled as the daily power source of the electric ship, and the bow propulsion inverter is controlled as the power source for the bow propulsion of the electric ship.

[0070] For example, if the initial stage of the electric ship's voyage is the unberthing mode, and the final stage of the voyage is the berthing mode, during the unberthing mode and the berthing mode, the left and right main propulsion devices still serve as the power source of the electric ship, while the right daily inverter such as INV2 is responsible for the daily power supply. In addition, the bow propulsion inverter such as BT-INV serves as the power source for the bow propulsion of the electric ship. The bow propulsion device is powered by a battery pack with an SOC of less than 30%, such as the 2# battery pack, and other aspects are consistent with the first and third stages of the normal navigation mode.

[0071] For another example, when the electric ship is in mooring mode and cannot access shore power, one of the battery packs is controlled to supply power to the AC distribution board, and each of the battery packs is controlled to charge and replace power in turn.

[0072] For example, in the mooring mode, the electric ship is in a stopped state and does not have the conditions to access the AC shore power. At this time, the battery pack provides power to the AC distribution board through the daily inverter. The battery pack can be charged or replaced.

[0073] When two DC switch cabinets are respectively arranged on both sides of the electric ship and each battery pack is connected to one of the two DC switch cabinets, in terms of charging: when the battery pack connected to the left DC switch cabinet needs to be charged, a battery pack connected to the right DC switch cabinet can be used to provide power to the AC distribution board through INV2. Conversely, when the battery pack connected to the right DC switch cabinet needs to be charged, a battery pack connected to the left DC switch cabinet can be used to provide power to the AC distribution board through INV1. The control of the specific charging process is similar to the charging process in the shore power mode.

[0074] In terms of battery replacement: when the battery pack connected to the left DC switch cabinet needs to be replaced, a battery pack connected to the right DC switch cabinet can be used to provide power to the AC distribution board through INV2. When the battery pack connected to the right DC switch cabinet needs to be replaced, a battery pack connected to the left DC switch cabinet can be used to provide power to the AC distribution board through INV1. The control of the specific battery replacement process is similar to the battery replacement process in shore power mode.

[0075] For another example, when the electric ship is in shore power mode, the AC distribution board of the electric ship is powered based on the AC shore power. The battery packs to be charged that are not fully charged are determined from the battery packs, and the battery packs to be charged are charged in turn based on the remaining power of the battery packs to be charged.

[0076] For example, in the shore power mode, the electric ship is in a stopped state and successfully connected to the AC shore power. The AC shore power provides power to the AC distribution board, and also provides convenient conditions for charging or replacing the battery pack.

[0077] Charging: When a DC charging device is provided on the shore, you only need to insert the DC charging gun into the DC shore power box DC / SC on the electric ship, and set the charging sequence of the battery packs, and then charge the battery packs one by one. After charging starts, the PMS controls the contactor of the first battery pack node A to close, and closes the DC molded case circuit breaker of the DC shore power box corresponding to the node A, and then starts charging. When the battery pack is fully charged, the PMS controls the contactor of the corresponding node A to disconnect, and selects the contactor of the second battery pack node A to close and start charging in the set order, and so on, charging one by one.

[0078] Battery swapping: The battery swapping station is powered by an AC shore power box through an AC distribution board. During the battery swapping process, the node contactors of all battery packs are in a disconnected state, and the battery swapping station will replace each battery pack in the set order.

[0079] In shore power mode, the intelligent charging and battery replacement strategies enable efficient and orderly management of battery packs. Whether it is DC charging or battery replacement, no manual intervention is required. PMS can accurately control the process and automatically charge or replace the battery pack in the set order, greatly improving the efficiency and accuracy of charging and battery replacement and reducing the error rate of operation.

[0080] In this embodiment, in order to meet the needs of different scenarios, both DC charging and AC power replacement are supported. By supporting multiple working modes such as normal navigation, berthing, unberthing, shore power and mooring, the power distribution strategy can be automatically adjusted according to the actual working conditions of the electric ship, ensuring the stable operation of the ship in various situations.

[0081] The power supply control scheme of the electric ship in the embodiment of the present invention adopts a distributed DC integrated power system, connects multiple battery packs to each battery cabinet respectively, and realizes efficient and intelligent battery pack control and management through the power management system (PMS). The distributed DC power system is adopted to disperse the power management function to each battery cabinet, which effectively reduces the complexity of the system, reduces the risk of single point failure, and greatly improves the reliability and stability of the system. The power management system automatically adjusts the power supply strategy according to the SOC status of each battery pack to ensure stable power supply for the main propulsion device and daily power supply. When the battery pack SOC drops to the preset power threshold, the battery pack is automatically switched to avoid the risk of electric ship suspension due to battery exhaustion and improve the reliability of power supply.

[0082] In order to execute the corresponding steps in the above embodiments and various possible methods, a method for implementing a power supply control device for an electric ship is given below. Figure 4 , Figure 4 This is a functional module diagram of a power supply control device 140 for an electric ship provided in an embodiment of the present invention. The power supply control device 140 for an electric ship can be applied to a power management system in a distributed power system, and the distributed power system also includes multiple battery packs for powering the electric ship. It should be noted that the power supply control device 140 for an electric ship provided in this embodiment has the same basic principles and technical effects as those of the above-mentioned method embodiment. For the sake of brief description, for parts not mentioned in this embodiment, reference can be made to the corresponding contents in the above-mentioned method embodiment. The power supply control device 140 for an electric ship includes an information acquisition module 141 and an information processing module 142.

[0083] The information acquisition module 141 is used to obtain the power consumption mode of the electric vessel.

[0084] The information processing module 142 is used to find out a target allocation strategy that matches the power usage mode from the pre-stored power allocation strategies; and control the working state of each battery pack based on the target allocation strategy.

[0085] On the basis of the above, an embodiment of the present invention further provides a computer-readable storage medium, which includes a computer program. When the computer program is running, it controls the electronic device where the computer-readable storage medium is located to execute the above-mentioned power supply control method for the electric ship.

[0086] The power supply control scheme for electric ships provided in the embodiment of the present invention adopts a distributed DC integrated power system, and the power supply is controlled by the power management system PMS, so that each battery pack can be independently powered in sequence to meet the power demand of the electric ship in normal navigation mode, berthing mode, unberthing mode, parking mode, shore power mode and other working conditions. Based on the PMS, the SOC status of the battery pack is monitored in real time, and the power supply strategy is automatically adjusted according to different navigation modes and working conditions. When the battery pack is low on power, the battery pack can be seamlessly switched to ensure the continuous and stable power supply of the main propulsion device and daily power supply of the electric ship to avoid navigation interruption. The use of clean energy for power supply reduces carbon emissions and is in line with the global environmental protection trend. Through intelligent power management and efficient energy utilization, the operating cost of electric ships is reduced and the economic benefits are improved.

[0087] Based on PMS, real-time monitoring of battery status is achieved, fault diagnosis and remote management are supported, and strong support is provided for the intelligent operation and maintenance of electric ships. It has significant advancement and innovation in power management, battery life, charging and battery replacement, and provides new ideas and methods for the development of electric ship technology, which is of great significance to the development of battery replacement ship technology.
