It should be understood that the data used in this way can be interchanged where appropriate, so that the embodiments of the present invention described herein can be implemented in an order other than those illustrated or described herein. In addition, the terms "including" and "having" and any variations thereof are intended to cover non-exclusive inclusions, for example, a process, method, system, product or device that includes a series of steps or units is not necessarily limited to those steps or units that are clearly listed, but may include other steps or units that are not clearly listed or inherent to these processes, methods, products or devices.

[0043] An embodiment of the present invention provides a ship container battery management system. Figure 1 This is a schematic diagram of the structure of a ship container battery management system provided by an embodiment of the present invention. Figure 1 The ship container battery management system includes: at least one battery management module 1, a cluster control management module 2, a first control module 3 and a second control module 4. The battery management module 1 is connected to at least one battery pack and is used to collect data information of each battery cell in the battery pack. The cluster control management module 2 is set corresponding to the battery cluster, and the cluster control management module 2 is connected to the battery management module 1, and is used to generate status information of the battery cluster according to the data information; the battery cluster includes at least one battery pack. The first control module 3 and the second control module 4 are interconnected and redundant to each other. The first control module 3 and the second control module 4 are both connected to each cluster control management module 2. The first control module 3 or the second control module 4 is used to control the cluster control management module 2 to manage the connection or disconnection of the battery cluster according to the data information and / or status information.

[0044] For example, a ship may include multiple container batteries. The container battery is composed of battery clusters, and the battery clusters can be set to multiple. Each battery cluster may include multiple battery packs, and the cells in the battery packs are charged and discharged. After the ship container battery is loaded on board, it can be regarded as a ship battery system.

[0045] The battery management module 1 can be used to collect data information of each battery cell in the battery pack, and the data information may include the temperature, current, voltage and other information of the battery cell. The cluster control management module 2 can calculate the status information of the battery cluster based on the data information of each battery cell, and the status information may include the power and health status of the battery cluster and other information.

[0046] The first control module 3 and the second control module 4 can be used to manage the battery cluster. When the battery cluster is running, the first control module 3 and the second control module 4 can simultaneously obtain the data information and status information of the battery cluster and judge the operating status of the battery cluster. When the temperature or voltage and other parameters of the battery cluster are abnormal, the first control module 3 or the second control module 4 can control the switch device in the battery cluster to cut off, thereby cutting off the connection between the battery cluster and the power supply or the power-consuming equipment. The first control module 3 and the second control module 4 can also transmit the data information and status information of the battery cluster to other systems in the ship, thereby realizing data interaction, and can also assist in the status monitoring and control of the battery cluster.

[0047] The first control module 3 and the second control module 4 are mutually redundant, so at the same time, only one control module can realize the control of the battery cluster. For example, when the first control module 3 is used as the main control module, the second control module 4 can be a backup control module, and the first control module 3 can shield the control signal of the second control module 4. Therefore, at the same time, only one control module can control the battery cluster, avoiding the control conflict of the battery cluster caused by multiple control signals.

[0048] The first control module 3 and the second control module 4 can also exchange internal data, so the first control module 3 and the second control module 4 can be used as hot standby. When one of the control modules is abnormal, the other control module can be put into use immediately. Because the data in the control module includes all the data in the abnormal control module, this setting method greatly reduces the risk of data loss, improves the reliability of data, and has a better control effect.

[0049] For example, when the first control module 3 serves as the main control module, if an abnormality occurs in the first control module 3 , the second control module 4 can detect abnormal data of the first control module 3 . At this time, the second control module 4 switches to the main control module and cuts off the first control module 3 .

[0050] The technical solution provided in the embodiment of the present invention realizes the control of the battery cluster by setting the first control module 3 and the second control module 4. The first control module 3 and the second control module 4 are hot standby for each other. When one of the control modules is abnormal, the other control module still has complete data and can directly replace the abnormal control module to work, which has high reliability. The first control module 3 and the second control module 4 provided by the present invention are redundant with each other, and the battery cluster can be controlled by only one control module, which has a good control effect. Therefore, the present invention improves the reliability of the battery management system and has a good control effect.

[0051] Continue to refer Figure 1On the basis of the above embodiments, optionally, the first control module 3 is connected to the first interface of the second control module 3 through the first interface, and the first interface is used to transmit the operation data of the first control module 3 and the second control module 4. The first control module 3 switches the main operation mode or the standby operation mode of the second control module 4 according to the operation data of the second control module 4; the second control module 4 switches the main operation mode or the standby operation mode of the first control module 3 according to the operation data of the first control module 3. The first control module 3 is connected to the second interface of the second control module 4 through the second interface, and the first control module 3 and the second control module 4 are used to generate detection data according to data information and / or status information. The second interface of the first control module 3 is used to transmit the detection data of the first control module 3 to the second interface of the second control module 4; the second interface of the second control module 4 is used to transmit the detection data of the second control module 4 to the second interface of the first control module 3.

[0052] Wherein, the first interface may be an I / O (Input / Output) interface, and illustratively, the operation data may include: a ready signal RFU (RFU-Ready for use) signal and a main operation signal. The ready signal may be used to indicate whether the first control module 3 or the second control module 4 meets the switching state of hot standby. Exemplarily, the ready signal may be used to perform a comprehensive diagnosis on the first control module 3 and the second control module 4. For example, to detect a software failure, a hardware failure, an internal communication failure or an external communication failure in the module. When a partial failure occurs, it does not meet the switching state of hot standby, that is, exits the standby operation mode.

[0053] Only one of the first control module 3 and the second control module 4 is in the main operation mode at the same time. Therefore, at the same time, the same one of the first control module 3 and the second control module 4 outputs a main operation signal, and the main operation signal can be used to shield the control signal output by the other control module to the cluster control management module 2. Exemplarily, the first control module 3 and the second control module 4 may include a CCU (Central Control Unit, central control unit), the battery management module 1 may include a BMU (Battery Management Unit, battery management unit), and the cluster control management module 2 may include a BCU (Battery Control Unit, battery control unit).

[0054] Figure 2 This is a schematic diagram of the structure of a control module provided by an embodiment of the present invention. Figure 2Optionally, the control module includes: an operation data generating unit 31, a detection data generating unit 32 and a data storage unit 33. The operation data generating unit 31 is connected to the detection data generating unit 32, and the detection data generating unit 32 is connected to the data storage unit 33. The operation data generating unit 31 of the first control module 3 is connected to the operation data generating unit 31 of the second control module 4 through a first interface, and the detection data generating unit 32 of the first control module 3 is connected to the detection data generating unit 32 of the second control module 4 through a second interface.

[0055] Among them, the data storage unit 33 can be used to store data information and status information, and the detection data generation unit 32 can be used to generate detection data according to the data information and status information. The detection data may include the redundancy of the operation of the first control module 3 and the second control module 4, the temperature, current or voltage change of each battery cell and the overall operation data of the battery cluster. The first control module 3 and the second control module 4 can exchange detection data through the second interface. Exemplarily, the second interface can be an RS485 communication interface.

[0056] The operation data generating unit 31 can be used to generate a ready signal and a main operation signal. Exemplarily, when the states of the ready signal and the main operation signal of the first control module 3 are both ON, and the state of the ready signal of the second control module 4 is ON and the state of the main operation signal is OFF, the first control module 3 is in the main operation mode, and the second control module 4 is in the standby operation mode.

[0057] Figure 3 This is a schematic diagram of the structure of another ship container battery management system provided by an embodiment of the present invention. Figure 3 On the basis of the above embodiments, optionally, the battery management module 1 includes: a first battery management unit 11 and a second battery management unit 12. The first battery management unit 11 is connected between the battery pack 10 and the cluster control management module 2, and is used to collect data information of each battery cell in the battery pack 10. The second battery management unit 12 is connected to the battery pack 10, and the second battery management unit 12 is also connected to the first control module 3 and the second control module 4, and is used to collect temperature information of each battery cell in the battery pack 10; wherein the data information includes temperature information.

[0058] Among them, when managing various battery data information, temperature information is one of the very important parameters. Therefore, by setting the second battery management unit 12, the temperature information can be collected separately. When one of the first battery management unit 11 or the second battery management unit 12 fails, the other battery management unit can still collect the temperature information of each battery cell in the battery pack 10. This setting method can ensure the safe operation of the battery pack 10 to the greatest extent. When a battery pack 10 has an abnormal temperature, the first control module 3 or the second control module 4 can directly cut off the battery cluster where the battery pack 10 is located to avoid further increase in temperature.

[0059] Continue to refer Figure 3 On the basis of the above embodiments, optionally, the ship container battery management system further includes: a battery cluster router 5, which is arranged corresponding to the battery cluster, the battery cluster router 5 is connected to the second battery management unit 12, and the battery cluster router 5 is also connected to the first control module 3 and the second control module 4, for transmitting the temperature information of each battery cell to the first control module 3 and the second control module 4.

[0060] Among them, the battery cluster router 5 can transmit the temperature information independently without going through the cluster control management module 2. Through this setting, even if the cluster control management module 2 is abnormal and cannot work, the first control module 3 and the second control module 4 can still receive the temperature information of each battery cell in the battery cluster through the battery cluster router 5, thereby improving the safety of battery operation.

[0061] Figure 4 This is a schematic diagram of the structure of another ship container battery management system provided by an embodiment of the present invention. Figure 4 On the basis of the above embodiments, optionally, the ship container battery management system further includes: a ship system module 6, redundantly connected to the first control module 3 and the second control module 4, for controlling the operation of the ship. The ship system module 6 includes: at least one of a full-ship extended display unit 61, a ship detection alarm unit 62, a ship intelligent data unit 63, a ship energy management unit 64, a ship propulsion control unit 65, a ship battery health monitoring unit 66, a ship data remote transmission unit 67, and a shore-based charging unit 68.

[0062] in, Figure 4 The configuration of eight battery clusters corresponding to eight cluster control management modules 2 is shown in an exemplary manner, and the first control module 3 and the second control module 4 can receive data information and status information of all battery clusters. The ship system module 6 can control the ship according to the data information and status information.

[0063] Specifically, the whole ship extended display unit 61 is a device for extending the display of key information in the first control module 3 and the second control module 4. It can be set at different locations of the ship to facilitate the crew to view battery-related information in real time.

[0064] The ship detection alarm unit 62 may include an AMS (Automated Monitoring System), which is a comprehensive system for automated monitoring and alarming of ships. It monitors the ship system in real time and can quickly issue an alarm once an abnormal situation is found to ensure the safe operation of the ship.

[0065] The ship intelligent data unit 63 can be used to collect and integrate the information in the first control module 3 and the second control module 4, thereby achieving standardization and normalization of the data.

[0066] The ship energy management unit 64 may include an EMS (Energy Management System), which is mainly used to comprehensively manage and optimize the generation, distribution, use and storage of ship electricity, thereby improving the ship's energy utilization efficiency, reducing operating costs, reducing environmental pollution, and ensuring the safe and stable operation of the ship.

[0067] The ship propulsion control unit 65 may include a PCS (Propulsion Control System), which is a system on a ship for controlling the ship's propulsion power device. Its main function is to accurately control the propulsion force of the ship so that the ship can sail according to the set speed, heading and other requirements, while ensuring the safe and efficient operation of the propulsion device.

[0068] The ship battery health monitoring unit 66 may include a BHMS (Battery Health Monitoring System) for monitoring the state and health of the ship battery.

[0069] The ship data remote transmission unit 67 may include a DTS (Data Transmission System for Ships), which is a system for transmitting ship data from the ship to a remote location (such as an onshore data center, a ship management company office, etc.).

[0070] The shore-based charging unit 68 may include a BCS (Shore-based Charging System), which is a facility for charging docked ships.

[0071] Continue to refer Figure 4On the basis of the above embodiments, optionally, the ship container battery management system further includes: a first local area network 71 and a second local area network 72. The first control module 3 is connected to the ship system module 6 through the first local area network 71, and the second control module 4 is connected to the ship system module 6 through the second local area network 72; the first local area network 71 and the second local area network 72 are redundant. Among them, the first control module 3 and the second control module 4 both communicate with the ship system module 6 through the Modbus protocol and / or the MQQT protocol.

[0072] Among them, due to the large size of the ship, the use of commonly used CAN communication (Controller Area Network) will inevitably lead to lower communication speed and shorter communication distance. By setting up the first local area network 71 and the second local area network 72, the communication distance between the first control module 3 and the second control module 4 will be greatly increased. And the communication method using the Modbus protocol and / or the MQQT protocol has better compatibility.

[0073] In the same local area network, the first control module 3 and the second control module 4 can exchange data with multiple units in the ship system module 6, thereby realizing information exchange between a physical connection and multiple systems, thereby greatly saving the number and types of port cables, reducing the complexity of ship cables, further improving the reliability of the system and reducing operation and maintenance costs.

[0074] The first LAN 71 and the second LAN 72 can be set up as redundancy. When one of the LANs fails, the other LAN can still transmit data, which has high reliability.

[0075] Continue to refer Figure 4 On the basis of the above embodiments, optionally, the ship container battery management system further includes: a first Ethernet communication interface 81 and a second Ethernet communication interface 82. The first control module 3 is connected to the first local area network 71 through the first Ethernet communication interface 81, and the second control module 4 is connected to the second local area network 72 through the second Ethernet communication interface 82. The first Ethernet communication interface 81 and the second Ethernet communication interface 82 are mutually redundant. The first Ethernet communication interface 81 includes: an independent information plug and socket. The second Ethernet communication interface 82 includes: an independent information plug and socket.

[0076] Exemplarily, the first Ethernet communication interface 81 and the second Ethernet communication interface 82 may be built with an isolation transformer or an optical coupler, which can isolate the transmitted signal, thereby ensuring the purity of the signal. When an interface failure occurs, such as water ingress and short circuit of the information plug, or the information plug falling off and breaking the circuit, the first Ethernet communication interface 81 and the second Ethernet communication interface 82 will not cause the failure to further expand, thereby avoiding interference with other lines. The first Ethernet communication interface 81 and the second Ethernet communication interface 82 are mutually redundant. When one Ethernet communication interface fails, the other Ethernet communication interface can still ensure the normal transmission of data, and has high reliability.

[0077] Continue to refer Figure 4 On the basis of the above embodiments, optionally, the ship container battery management system includes: at least two battery clusters, the cluster control management module 2 is set in one-to-one correspondence with the battery cluster; the battery management module 1 is set in one-to-one correspondence with the battery pack.

[0078] The operations of the battery clusters are independent of each other, and the first control module 3 and the second control module 4 can independently control the battery clusters. Figure 4 The configuration of eight battery clusters corresponding to eight cluster control management modules 2 is shown as an example. It should be noted that: Figure 4 The eight battery clusters are only one of the configurations of the ship container battery management system, and there is no limit on the number of battery clusters. The first control module 3 and the second control module 4 can receive data information and status information of all battery clusters. For example, when the total storage capacity of the container battery is maximized to 2000kWh, it is more reasonable for one container battery to accommodate eight battery clusters.

[0079] Continue to refer Figure 4 On the basis of the above embodiments, optionally, the ship container battery management system further includes: a battery field control unit 91, a battery auxiliary control unit 92, a battery global positioning unit 93 and a battery remote data transmission unit 94. The battery field control unit 91 is connected to the first control module 3 and the second control module 4 for field control of the ship container battery. The battery auxiliary control unit 92 is connected to the first control module 3 and the second control module 4 for auxiliary control of the ship container battery. The battery global positioning unit 93 is connected to the first control module 3 and the second control module 4 for positioning the ship container battery. The battery remote data transmission unit 94 is connected to the first control module 3 and the second control module 4 for transmitting data of the ship container battery.

[0080] The battery field control unit 91 may include a field control screen for displaying the container battery status and controlling it on site. The battery auxiliary control unit 92 may control the auxiliary control system of the container battery, thereby improving the reliability of the battery cluster management. The battery global positioning unit 93 may be used to locate the location of the container battery. The battery remote data transmission unit 94 may be used to transmit the container battery data to a remote location, such as a data center on shore.

[0081] Exemplarily, the battery auxiliary control unit 92 may include an auxiliary control system inside the container battery. When the auxiliary control system fails to work properly, such as battery cooling control, container environment control, etc., this fault is a serious fault, and the container battery will stop working and stop providing power to the ship. In order to ensure the safety of the ship, the battery management module 1 and the cluster control management module 2 can still upload their respective data to the first control module 3 and the second control module 4. Therefore, even if the auxiliary control system fails to work properly, the first control module 3 and the second control module 4 can still effectively monitor the container battery, thereby ensuring the safety of the ship.

[0082] The embodiment of the present invention further provides a transport ship, which comprises a container battery and a ship container battery management system as provided by any embodiment of the present invention, and has similar beneficial effects as the ship container battery management system provided by any embodiment above, which will not be described in detail here.

[0083] It should be understood that the various forms of processes shown above can be used to reorder, add or delete steps. For example, the steps described in the present invention can be executed in parallel, sequentially or in different orders, as long as the desired results of the technical solution of the present invention can be achieved, and this document does not limit this.

[0084] The above specific implementations do not constitute a limitation on the protection scope of the present invention. It should be understood by those skilled in the art that various modifications, combinations, sub-combinations and substitutions can be made according to design requirements and other factors. Any modification, equivalent substitution and improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
