Description

Technical Field

[0001] This invention relates to the field of marine power equipment technology, specifically to a method and product for efficient adaptation of a marine containerized mobile power supply to a ship-to-shore energy interface. Background Technology

[0002] Traditional oil-fired ships emit exhaust gases, impacting the environment. Therefore, against the backdrop of the shipping industry's transformation towards green, environmentally friendly, and energy-efficient utilization, marine containerized mobile power supplies are increasingly widely used as a core power supply carrier for ships. These power supplies can be directly hoisted onto the deck for power generation and easily hoisted ashore for charging. They are playing an increasingly important role in short-distance, coastal, and inland waterway transportation. Currently, ship power management systems, containerized mobile power supplies, and propulsion motors are typically packaged and provided by a single integrator. Their electrical interfaces and communication protocols use the integrator's internal standards, resulting in mobile power supplies only being compatible with ships of the same type.

[0003] The lack of standardized electrical interface types and communication protocols among different manufacturers of marine containerized mobile power supplies has caused numerous problems:

[0004] When charging and swapping power banks at different ports, they are difficult to adapt to the port charging and swapping stations and cannot be quickly interchanged.

[0005] The incompatibility of mobile power supplies from different suppliers limits the flexibility of ships in choosing power suppliers, and also leads to poor data exchange, poor compatibility, and a significant increase in usage costs.

[0006] Differences in communication protocols prevent mobile power supplies from smoothly exchanging data with ship power management systems, charging and swapping stations, and other systems, thus affecting the efficiency of collaborative work.

[0007] For ships of a certain tonnage that require short-term charging (such as ships entering the river during tidal times), existing interface designs are insufficient to meet fast charging requirements.

[0008] Inconsistent interfaces: Different manufacturers' power banks have different interface types, which makes it difficult to adapt when charging, swapping batteries, or switching suppliers across ports.

[0009] Insufficient adaptability: For scenarios requiring short-term charging, such as ships of specific tonnage or vessels entering rivers during tidal periods, existing interfaces and protocols cannot simultaneously ensure fast charging efficiency and safety and stability. Summary of the Invention

[0010] To address the problems of poor universality, difficulty in interchangeability, poor data exchange, and insufficient adaptability of existing marine containerized mobile power supplies, as well as the inability to flexibly adapt to the charging needs of different vessels (such as vessels of specific tonnage or entering rivers during tidal periods), this invention provides a method and product for efficient adaptation of marine containerized mobile power supplies to ship-shore energy interfaces. It can form standardized electrical interfaces and communication protocols, enabling the mobile power supply to be adapted to different ship power systems and port charging and swapping stations, achieving universal interchangeability of equipment, flexible fast charging, and balancing efficiency and safety.

[0011] The technical solution of the present invention is as follows:

[0012] A method for efficient adaptation of marine containerized mobile power supplies to ship-to-shore energy interfaces includes the following steps:

[0013] S1: Unified electrical interface for marine containerized power supplies based on the first constraint: The first constraint includes: the DC charging and discharging current capacity of the containerized mobile power supply electrical interface, the total storage capacity of a single battery compartment as specified by the classification society, and the charging time limit for vessels entering the river during tidal periods; The unified electrical interface includes the type of unified power interface, and clearly defines the number, size, and arrangement of each type, the pin functions of each interface, the wiring specifications, and the destination of each interface, etc., which can be set on the interface structure of the power supply box; The type of power interface includes rechargeable DC interface, AC interface, signal interface, and network interface;

[0014] S2: The electrical interfaces in S1 are standardized according to the second constraint: The second constraint includes: the applicable communication protocol approved by the classification society and the electrical interface selected in S1; The standardized communication protocol refers to the standardized communication protocol between the power supply and the ship's power management system, the standardized communication protocol between the power supply and the shore-based system or charging and discharging station, and the standardized communication protocol between the power supply and the remote control panel in the bridge, which are respectively standardized protocols.

[0015] The containerized mobile power supply's electrical interface DC charging and discharging current capacity includes 250A and 1000A. The classification society stipulates that the total storage capacity of a single battery compartment is no more than 2000 kWh. During tidal periods, the charging time for vessels entering the river is limited to within 2 hours.

[0016] The DC interface is equipped with six 250A interfaces, each of which includes power, grounding, communication, connection confirmation, and temperature monitoring functions. They are arranged in two parallel groups of three, located on the lower side of the power bank housing. Above the two groups of DC interfaces, there is a parallel 63A AC interface for external auxiliary power to supply power to the power bank, two horizontally arranged signal interfaces for communication with the power bank remote control in the cab, and two horizontally arranged network interfaces for data transmission. The signal socket is located above the network socket, next to the AC socket.

[0017] The DC interface is defined as follows:

[0018] Power interface: DC+, DC-, wiring specification is 2×120, destination is the ship's power management system;

[0019] Grounding interface: PE, wiring specification is 1×70;

[0020] Communication interfaces: S+, S- (to EMS / charging), wiring specifications are 1×2×0.75; ES1, ES2, wiring specifications are 6×1.0;

[0021] Connection confirmation interfaces: CC1, CC2 (to BMS);

[0022] Temperature monitoring interfaces: T1, T2, T3, T4 (not occupying a core).

[0023] The AC interface is a three-phase AC power interface: L1, L2, L3, with a wiring specification of 4×16 (including 1×16 PE wire). Its grounding interface is PE, with the same wiring specification as the three-phase AC power interface; the destination is an external auxiliary power supply.

[0024] Both of the aforementioned signal interfaces are 16-pin signal interfaces.

[0025] Signal Interface 1: Includes SOC low of battery pack #1, emergency stop of battery pack #1, fire common terminal (24V / 0V), fire leakage alarm, alarm, fire release alarm, fire alarm signal, power failure alarm (220V / 24V), emergency cut-off of water-cooled unit, and battery touch screen RS485. The wiring specification is 16×1.5, and the destination is the remote control panel in the driver's cab.

[0026] Signal interface 2: Includes signals such as low SOC of battery pack #2, emergency stop of battery pack #2, 20% combustible gas alarm, manual start / stop of fire protection (main / backup), common terminal, emergency fan emergency cut-off, and reset. The wiring specification is 16×1.5.

[0027] Both of the aforementioned network interfaces are 16-pin network interfaces.

[0028] Network Interface 1: Used for video Ethernet communication, pins 1-8 are for communication, pins 9-16 are spare, using CAT6 network cable, destination is CCTV system;

[0029] Network Interface 2: Used for Ethernet communication. Pins 1-8 are for communication, and pins 9-16 are for backup. It uses CAT6 network cable and is destined for the shore-based system.

[0030] The standardized protocol includes a communication protocol with the ship's electrical management system: data transmission is achieved through the S+ and S- lines in the 250A DC charging and discharging interface using the CAN protocol, enabling real-time data transmission of voltage, current, SOC (state of charge), etc.

[0031] Communication protocol with shore-based systems or charging / swapping stations: Communication is conducted via network interface 2 using the TCP / IP protocol: sending mobile power status data to the shore-based monitoring platform; and interacting with the port charging / swapping station management system to dynamically adjust charging power.

[0032] Communication protocol with the driver's cab remote control: Through pins 15 and 16 of signal interface 1, the MODBUS protocol is used to communicate with the remote control display screen, send battery status and alarm information to the driver's cab remote control, and transmit mobile power supply status information (such as SOC, alarm signal, etc.).

[0033] It also includes the following interactive features:

[0034] Identity authentication and information exchange function: The power bank sends its unique device identifier (serial number, model, rated parameters) through network interface 2. Communication is established after the shore system or charging and swapping station verifies the information.

[0035] The present invention also includes an interface provided on the power bank housing by the method.

[0036] Technical effects:

[0037] This invention solves the problems of poor universality, difficulty in interchangeability, poor data exchange, and insufficient adaptability caused by inconsistent electrical interfaces and communication protocols in marine containerized power supplies. It also addresses the inability to flexibly adapt to the charging needs of different vessels (such as vessels of specific tonnage or those entering rivers during tidal periods). Specifically, in the field of marine containerized power supplies, this invention is the first to propose that the electrical interface must meet the first constraint: uniformly considering the DC charging and discharging current capacity of the power supply's electrical interface, the total storage capacity of a single battery compartment as specified by the classification society, and the charging time restrictions for vessels entering rivers during tidal periods. All necessary conditions are comprehensively considered to meet the unique and diverse needs of marine containerized power supplies. The unified electrical interface includes a unified type of power interface, and the types, quantities, sizes, and layouts of each type, as well as the pin functions, wiring specifications, and destinations of each interface, are comprehensively considered to construct the types, quantities, sizes, and layouts of the interfaces, thus solving problems such as interface inconsistency, poor universality, and difficulty in interchangeability. Meanwhile, this invention, for the first time, proposes satisfying the second constraint condition: namely, meeting the communication protocol specified by the classification society and the unified communication protocol of the electrical interface selected by S1. This solves the problems of poor universality, difficulty in interchangeability, poor data exchange, and insufficient adaptability caused by inconsistent communication protocols, and achieves efficient adaptation between marine containerized mobile power supplies and ship-to-shore energy interfaces. Therefore, this invention achieves the following beneficial effects:

[0038] 1) Enhance versatility and interchangeability: A unified electrical interface enables the power bank to be adapted to different ship power systems and port charging and swapping stations, achieving fast charging, battery swapping, and cross-supplier interchangeability;

[0039] 2) Achieve smooth data interaction: Standardized communication protocols solve the problem of collaborative operation between mobile power supplies and ship power management systems, shore-based platforms, and wheelhouse remote control panels;

[0040] 3) Break industry monopolies: reduce reliance on single integrators and promote market competition and technological innovation;

[0041] 4) Promote efficient development of the industry: Accelerate the large-scale application of marine containerized mobile power supplies and help the shipping industry achieve green and low-carbon transformation.

[0042] The device features six 250A DC sockets, each with power, grounding, communication, connection confirmation, and temperature monitoring functions. These are arranged in two parallel groups of three, located on the lower side of the power bank housing. Above these two groups of DC sockets, a 63A AC interface for external auxiliary power supply is arranged in parallel. A pair of horizontally positioned signal sockets for communication with the power bank's remote control in the cab, and a pair of horizontally positioned network sockets for data transmission are also included. The signal sockets are positioned above the network sockets. These features, located next to the AC sockets, enable flexible fast charging and safe operation. The six 250A DC sockets can be used individually or simultaneously. Combined with a maximum capacity of 1999 kWh, charging time is controlled to approximately 1.5 hours at a 0.6C rate, meeting the needs of ships of specific tonnages and vessels entering rivers during tidal periods requiring short-term charging. This also accommodates rapid hoisting and high-speed, safe charging. The 250A DC sockets are convenient to use, and the cable thickness is suitable for easy operation, whereas a 1000A cable would be too thick and inconvenient to install and remove.

[0048] The following is in conjunction with the appendix Figure 1 —Appendix Figure 5 Further explanation of the present invention:

[0049] A method for efficient adaptation of marine containerized mobile power supplies to ship-to-shore energy interfaces includes the following steps:

[0050] S1: A unified electrical interface for marine containerized power supplies is defined according to the first constraint: The first constraint includes: the DC charging and discharging current capacity of the mobile power supply electrical interface, the total storage capacity of a single battery compartment as specified by the classification society, and the charging time limit for vessels entering the river during tidal periods; The unified electrical interface includes a unified power interface type, and the quantity, size, and arrangement of each type, the pin functions, wiring specifications, and destinations of each interface, etc., which can be set on the interface structure of the power supply box are clearly defined; The power interface types include rechargeable DC interfaces, AC interfaces, signal interfaces, and network interfaces;

[0051] S2: The electrical interface in S1 is unified according to the second constraint: The second constraint includes: the communication protocol specified by the classification society and the electrical interface selected in S1; The unified communication protocol refers to the unified communication protocol between the power supply and the ship's power management system, the unified communication protocol between the power supply and the shore-based system or charging and discharging station, and the unified communication protocol between the power supply and the bridge remote control, forming standardized protocols respectively.

[0052] The containerized mobile power supply's electrical interface has DC charging and discharging current capacities of 250A and 1000A, and the classification society specifies that the total storage capacity of a single battery compartment should not exceed 2000 kWh; during tidal periods, the charging time for vessels entering the river is limited to within 2 hours. Specifically,

[0053] S1: The unified electrical interface for the marine containerized power supply according to the first constraint includes: According to the above first constraint, the interface arrangement of the marine containerized mobile power supply of the present invention is shown in Figure 1. Its design strictly follows the above first constraint to achieve a unified electrical interface.

[0054] Specifically as follows:

[0055] The marine containerized mobile power supply interface includes the following interfaces, and the pin functions, wiring specifications, and destinations of each interface are clearly defined:

[0056] 1) Based on the first constraint, the first step in unifying the electrical interfaces is to standardize the types of power interfaces, including four types: DC charging / discharging interfaces, AC interfaces, signal interfaces, and network interfaces. The quantity, size, and arrangement of each type, the pin functions, wiring specifications, and routing directions of each interface, as well as the interface structures that can be installed on the power supply enclosure, are clearly defined. For the DC charging / discharging interface configuration: see [link to documentation]. Figure 1 , Figure 2 It is equipped with 6 DC interfaces, and the interface layout is as follows: Figure 1 As shown, the connector and input socket structure is as follows: Figure 2As shown, the containerized mobile power supply is equipped with six 250A DC interfaces (DC sockets), each with a rated current of 250A, meeting the high-current charging and discharging requirements and adapting to the high-power power consumption scenarios on ships. The containerized mobile power supply's electrical interfaces have two specifications for DC charging and discharging current capacity: 250A and 1000A. Since the 1000A cable is too thick and inconvenient for installation and removal on board and shore, the 250A DC charging and discharging interfaces were chosen for ease of use. Each DC interface includes power, grounding, communication, connection confirmation, and temperature monitoring functions. Two groups of three are arranged in parallel on the lower side of the mobile power supply housing. Above the two groups of DC interfaces, a 63A AC interface (AC socket) for external auxiliary power supply to the mobile power supply is arranged in parallel. Two horizontally arranged signal interfaces (signal sockets) for communication with the mobile power supply remote control panel in the bridge, and two horizontally arranged network interfaces (network sockets) for data transmission are also provided. The signal sockets are located above the network sockets, next to the AC sockets. The lower location of the DC charging and discharging interfaces facilitates electrical connection to the DC power distribution management system on the ship's deck.

[0057] Classification societies stipulate that the total storage capacity of a single battery compartment should not exceed 2000 kWh, for example, 1999 kWh, which complies with the classification society's limit on the capacity of a single battery compartment. Regarding charging time restrictions for vessels entering the river during tidal periods: all six 250A DC interfaces can be used simultaneously. Combined with the limit of less than 2000 kWh capacity, a charging rate of approximately 0.6C can achieve a full charge within 1.5 hours, meeting the charging time restrictions for vessels during tidal periods, i.e., the need for short-time charging.

[0058] The DC interface is defined as follows:

[0059] Power interface: DC+, DC-, wiring specification is 2×120, destination is the ship's power management system;

[0060] Grounding interface: PE, wiring specification is 1×70;

[0061] Communication interfaces: S+, S- (to EMS / charging), wiring specifications are 1×2×0.75; ES1, ES2, wiring specifications are 6×1.0;

[0062] Connection confirmation interfaces: CC1, CC2 (to BMS);

[0063] Temperature monitoring interfaces: T1, T2, T3, T4 (not occupying a core).

[0064] The specific definitions are shown in Table 1:

[0065] Table 1. Definition of 250A Charge / Discharge DC Interface

[0066]

[0067] 2) For the communication interface, set up one 63A communication interface:

[0068] See Figure 3 The AC interface is a three-phase AC power interface: L1, L2, L3, with a wiring specification of 4×16 (including 1×16 PE wire). Its grounding interface is PE, with the same wiring specification as the three-phase AC power interface; the destination is an external auxiliary power supply.

[0069] This AC interface is used for an external auxiliary power supply to power the power bank. The interface definition is shown in Table 2.

[0070] Table 2 63A AC Interface Definition Table

[0071]

[0072] 3) For the signal interfaces, set up 2 signal interfaces:

[0073] See Figure 4 The two signal interfaces are 16-pin signal interfaces. Signal interface 1 includes signals for battery pack #1 SOC low, battery pack #1 emergency stop, fire common terminal (24V / 0V), fire leakage alarm, alarm, fire release alarm, fire alarm signal, power failure alarm (220V / 24V), water-cooled unit emergency cut-off, and battery touch screen RS485. The wiring specification is 16×1.5, and the destination is the driver's cab remote control panel. Signal interface 2 includes signals for battery pack #2 SOC low, battery pack #2 emergency stop, combustible gas 20% alarm, fire manual start / stop (main / backup), common terminal, emergency fan emergency cut-off, and reset. The wiring specification is 16×1.5.

[0074] Used for communication with the mobile power supply remote control panel in the driver's cab, the specific definitions are shown in Table 3:

[0075] Table 3 Signal Interface Definition Table

[0076]

[0077] 4) Configure two network interfaces:

[0078] See Figure 5 The two network interfaces are 16-pin network interfaces. Network interface 1 is used for video Ethernet communication, with pins 1-8 being the communication cable and pins 9-16 being spares. It uses CAT6 network cable and is destined for the CCTV system. Network interface 2 is used for Ethernet communication, with pins 1-8 being the communication cable and pins 9-16 being spares. It uses CAT6 network cable and is destined for the shore-based system.

[0079] Used for data transmission, the specific definitions are shown in Table 4:

[0080] Table 4 Network Interface Definition Table

[0081] The electrical interfaces in S2 and S1 use a unified communication protocol based on the second constraint condition:

[0082] The design of the unified communication protocol follows the second constraint (communication protocol approved by the classification society and communication protocol adapted to the electrical interface specified in S1). Standardized protocols are selected for different interaction objects, as follows:

[0083] Classification society-approved communication protocols: Select from classification society-approved protocols such as CAN, TCP / IP, and MODBUS to ensure communication compliance;

[0084] 1) Standardization of communication protocols with the ship's electrical management system:

[0085] Data exchange is achieved via the S+ and S- lines of the 250A DC charging / discharging interface using the CAN protocol. The mobile power bank's battery management system (BMS) transmits real-time data such as voltage, current, and SOC (state of charge) to the ship's power management system through this protocol.

[0086] 2) Unification of communication protocols with shore-based systems or charging / swapping stations:

[0087] Communication is conducted via network interface 2 using the TCP / IP protocol.

[0088] Send mobile power bank status data to the shore-based monitoring platform; transmit mobile power bank status information to the port charging and swapping station management system, and dynamically adjust charging power.

[0089] 3) Standardization of communication protocol with the driver's cab remote control:

[0090] Through pins 15 and 16 of signal interface 1, the device communicates with the remote control display screen using the MODBUS protocol, sending battery status and alarm information to the remote control board in the driver's cab, and transmitting mobile power supply status information (such as SOC, alarm signals, etc.).

[0091] The present invention also includes the following interactive functions: identity authentication and information interaction function: the power bank sends a unique identifier such as device serial number, model, and rated parameters through network interface 2, and establishes communication after the shore-based system or charging and swapping station verifies the information.

[0092] The present invention also relates to an interface provided by the method on the power bank housing.

[0093] The application of the interface product of this invention when ships are docked at ports is as follows:

[0094] After the power bank is lifted off the ship and transported to the charging station, it connects to the management system of the charging and swapping station through network interface 2. It uses the aforementioned TCP / IP protocol to handshake with the management system of the charging and swapping station, transmits the battery status data of the power bank, and dynamically adjusts the charging power.
