[0041] Figure 1 is a flowchart of a battery box management method for a ship provided by the present application, as shown in Figure 1 , including:

[0042] Step S101: The battery intelligent management terminal in the first battery box currently supplying power to the ship sends the real-time acquired power information and state information of each battery pack in the first battery box to the battery intelligent management platform, so that the battery intelligent management platform determines whether the first battery box can continue to supply power to the ship according to the power information and state information of each battery pack in the first battery box.

[0043] Step S102: When the battery intelligent management platform determines that the first battery box cannot continue to supply power to the ship, the battery intelligent management platform sends a power-off instruction to the battery intelligent management terminal in the first battery box and a power-on instruction to the battery intelligent management terminal in the second battery box.

[0045] Step S104: The battery intelligent management terminal in the second battery box closes the power supply switch of the second battery box according to the power-on instruction, so that the second battery box supplies power to the ship.

[0046] Specifically, the ship has at least two battery boxes, each battery box has a capacity of 2000kWh, a standard voltage of 600V, and a standard current of 1000A; each battery box contains two battery clusters, and each battery cluster contains 60 battery packs; wherein one battery cluster in the battery box supplies power to the ship during ship operation.

[0047] Further, the battery intelligent management platform determines whether the first battery box can continue to supply power to the ship according to the power information and state information of each battery pack in the first battery box, including: when the battery intelligent management platform determines that the power information of the first preset number of battery packs in any battery cluster of the first battery box is higher than the preset power threshold, and the state information of the second preset number of battery packs in any battery cluster of the first battery box meets the power supply state, the battery intelligent management platform determines that the first battery box can continue to supply power to the ship; when the battery intelligent management platform determines that the power information of the first preset number of battery packs in both battery clusters of the first battery box is lower than the preset power threshold, the battery intelligent management platform determines that the first battery box cannot continue to supply power to the ship; or when the battery intelligent management platform determines that the state information of the second preset number of battery packs in both battery clusters of the first battery box does not meet the power supply state or any battery pack in any battery cluster has a serious fault, the battery intelligent management platform determines that the first battery box cannot continue to supply power to the ship.

[0048] The embodiment of the present application further comprises: when the battery packs in the first battery cluster of the first battery box are powering the ship, the battery intelligent management terminal of the first battery box acquires the power information and state information of each battery pack in the first battery cluster in real time, and judges whether the first battery cluster can continue to power the ship according to the power information and state information of each battery pack in the first battery cluster; when it is judged that the first battery cluster cannot continue to power the ship and no power-off instruction sent by the battery intelligent management platform is received, the battery intelligent management terminal of the first battery box switches from the first battery cluster to the second battery cluster through the switch, so that the second battery cluster powers the ship.

[0049] The embodiment of the present application further comprises: when the battery intelligent management platform detects that the ship needs to be replaced with batteries, the battery intelligent management platform searches for a battery replacement wharf corresponding to the position of the ship according to the position information of the ship, and sends the position information of the battery replacement wharf to the ship management terminal, so that the ship management terminal controls the ship to drive to the battery replacement wharf, and the battery replacement wharf performs battery box replacement operation on the ship.

[0050] Further, the ship management terminal controls the ship to drive to the ship battery replacement station, and the ship battery replacement station performs battery box replacement operation on the ship, which comprises: when the ship management terminal detects that the ship reaches the battery replacement wharf area, the ship management terminal starts the ultra-wideband (UWB) tag on the ship, so that the UWB tag on the ship acquires the current positioning information of the ship in real time, and sends the current positioning information to the UWB base station of the battery replacement wharf, so that the UWB base station calculates the battery position information of the ship for placing the battery box according to the positioning information; the UWB base station generates a ship dynamic position chart containing the battery position information of the ship according to the battery position information of the ship and the effective battery replacement position area of the battery replacement wharf, and sends the ship dynamic position chart containing the battery position information of the ship to the ship management terminal; the ship management terminal monitors whether the battery position information of the ship meets the battery replacement position requirement according to the ship dynamic position chart containing the battery position information of the ship in real time; when it is monitored that the battery position information of the ship meets the battery replacement position requirement, the ship management terminal sends a battery replacement request to the battery replacement station control system of the battery replacement wharf, so that the battery replacement station control system performs automatic battery replacement operation on the ship according to the battery replacement request.

[0051] The UWB tag comprises: a first UWB tag arranged at the bow position of the ship and a second UWB tag arranged at the stern position of the ship; and the battery replacement position area comprises: a first battery replacement position area located on the left side of the battery replacement wharf, a second battery replacement position area located on the right side of the battery replacement wharf, and a third battery replacement position area located on the front side of the battery replacement wharf.

[0052] The ship management terminal detecting that the ship reaches the battery replacement wharf area refers to that when the ship management terminal monitors that the ship travels to a preset distance from the battery replacement wharf, the first UWB tag and the second UWB tag are started, and a first communication link between the first UWB tag and a UWB base station of the battery replacement wharf is established, and a second communication link between the second UWB tag and the UWB base station of the battery replacement wharf is established; the first UWB tag acquires first positioning information of a ship bow position in real time, and periodically sends the first positioning information to the UWB base station through the first communication link, and at the same time, the second UWB tag acquires second positioning information of a ship stern position in real time, and periodically sends the second positioning information to the UWB base station through the second communication link.

[0053] Further, the UWB base station calculates the battery position information of the ship according to the positioning information, which comprises that the UWB base station calculates the battery position information of the ship according to the first positioning information and the second positioning information.

[0054] The embodiment of the application further comprises that the battery replacement station control system monitors whether there is a ship in the battery replacement position area in real time, and when it is monitored that there is a ship in the battery replacement position area, the battery replacement position area is regarded as an invalid battery replacement position area, and when it is monitored that there is no ship in the battery replacement position area, the battery replacement position area is regarded as a valid battery replacement position area, and the battery replacement position area information of the valid battery replacement position area is sent to the UWB base station.

[0055] Specifically, the ship management terminal monitors whether the battery position information of the ship meets the battery replacement position requirement according to the ship dynamic position chart containing the battery position information of the ship in real time, which comprises that the ship management terminal controls the ship to travel according to the ship dynamic position chart containing the battery position information of the ship, and when the battery position information of the ship is in the valid battery replacement position area of the battery replacement wharf, it is monitored that the battery position information of the ship meets the battery replacement position requirement.

[0056] The ship management terminal sends a battery replacement request containing a valid battery replacement position area to the battery replacement station control system of the battery replacement wharf, and the battery replacement station control system starts the battery replacement robot corresponding to the valid battery replacement position area according to the valid battery replacement position area in the battery replacement request; the battery replacement robot grasps the depleted battery box on the ship to a transfer position, grasps the full battery box in the battery container to the ship, and grasps the depleted battery box on the transfer position to the idle charging base in the battery container for charging; wherein the transfer position is located in the battery container or outside the battery container.

[0057] The ship management terminal adjusts the position information of the ship in the water in real time according to the ship dynamic position chart containing the battery position information of the ship during the automatic battery replacement operation of the ship, so that the battery position information of the ship is located in the valid battery replacement position area of the battery replacement wharf.

[0058] In addition, the battery replacement wharf in the application can be configured with a first battery replacement robot on the left side of the battery replacement wharf, a second battery replacement robot on the right side of the battery replacement wharf, and a third battery replacement robot on the front side of the battery replacement wharf, so that when the ship is located in any battery replacement position area, the corresponding battery replacement robot is started to perform battery replacement operation, so that three ships can be replaced at the same time, and the battery replacement speed is improved. At the same time, when the battery replacement wharf is located in a remote location, the same battery replacement robot can be configured for the first battery replacement position area, the second battery replacement position area and the third battery replacement position area, thereby saving costs.

[0059] Because the ship is easy to sway on the water, the position of the ship is unstable, so the battery position area on the ship is larger than the base area of the battery box, so that after the full battery box is grasped by the battery replacement robot to the battery position area on the ship, the full battery is adjusted to the appropriate effective battery position on the ship using the battery replacement equipment on the ship. The effective battery position is the battery position used for normal power supply on the ship.

[0060] The application also provides an automatic battery replacement system for a ship, comprising a ship and a battery replacement wharf, wherein the ship comprises a ship management terminal and a UWB tag, and the battery replacement wharf comprises a station control system and a UWB base station. Specifically, the ship management terminal is used for managing and controlling the entire process of battery replacement used by the ship, and the ship management terminal communicates with the monitoring and management system through a 4G network and transmits information to the battery replacement station control system for battery replacement operation. The UWB tag is a module for recording the positioning information of the ship, and the positions of the ship are continuously and accurately sent to the UWB base station through the two tags before and after the ship. The battery replacement station control system mainly performs the automatic replacement of the used batteries on the ship to the battery replacement station and then replaces the fully charged batteries in the station to the ship, so that the ship can run with full power. The UWB base station mainly obtains UWB tag information to calculate the position of the ship, plans the path of the ship into the station and the stop position, controls the power of the ship based on the planned path, and then dynamically adjusts the ship based on the real-time position of the ship to make the ship run to the specified position for battery replacement.

[0061] The UWB high-speed positioning real-time updates the position, which indicates that the difficulty of automatic battery replacement of the ship lies in the influence of water flow and wind direction, which causes the position of the ship to be always changing, so that the accuracy requirement of the automatic battery replacement of the ship is relatively high. Once the water flow and wind direction are too large, the replacement position deviates too much, the ship battery cannot be placed in the correct position, and the automatic battery replacement fails. The UWB high-speed data transmission and accurate position information are used to generate a position chart of the ship in real time, the position chart is compared with the marked battery replacement position of the ship in real time, the power system of the ship is controlled in time to adjust the position of the ship, so that the ship can be stopped in the position allowed for battery replacement at any time, and the battery replacement of the ship is safe, efficient and fast.

[0062] The ship battery replacement method specifically comprises the following steps.

[0063] S1, the ship management terminal integrated with the UWB precise positioning controls the direction of the ship running through the CAN communication mode, so that the ship is stopped at a position where the battery can be replaced.

[0064] The ship management terminal can not only accurately control the position where the ship is stopped, but also control the communication between the battery box on the ship and the battery replacement station, and then perform automatic battery replacement.

[0065] S2, when the ship runs to a distance of 1KM from the battery replacement wharf, the ship management terminal opens the UWB tag to perform handshaking and communication with the UWB base station on the battery replacement wharf, so that the high speed and unique transmission protocol of the UWB can quickly perform basic positioning.

[0066] S3, the UWB base station on the battery swap wharf determines the basic position of the ship through a special protocol, and then performs TDOA to calculate and plan the driving path, so as to guide the ship to enter the battery swap wharf, and then the UWB precise positioning mode is used to guide the ship to stop at a position where the battery can be swapped. Since the current ship battery swap requires a relatively strict position for the ship to stop, so as to perform the battery swap, the UWB-TDOA positioning mode completely meets the requirement of the precision of the battery swap position.

[0067] 3.1, the UWB-TDOA technology is used to accurately position the ship by using the time difference of arrival principle. According to the positioning information transmitted by the two tags at the bow and the stern, the UWB base station in the battery swap station will calculate and position the position according to the TDOA technology.

[0068] 3.2, the time difference of radio signal propagation between the two different positioning base stations is measured by using the UWB technology, so as to obtain the distance difference of the positioning tag relative to the two groups of positioning base stations.

[0069] 3.2, UWB-TDOA positioning principle

[0070] Using the TDOA technology does not require reciprocal communication between the positioning tag and the positioning base station, only the positioning tag transmits or receives the UWB signal, so that higher positioning dynamic and positioning capacity can be achieved.

[0071] S4, after the positioning is completed, the battery swap station control system guides the battery swap station of the battery swap wharf to automatically swap the battery. When the battery swap is completed, the battery swap station sends a battery swap completion instruction to the ship management terminal. After the ship management terminal receives the battery swap completion instruction, the UWB tag is turned off. At this time, the ship breaks the communication connection with the battery swap wharf, and normally drives away from the wharf. The next ship normally connects, normally swaps the battery, and the like.

[0072] S5, the UWB tag on the ship and the UWB base station on the battery swap wharf continuously transmit the real-time position of the ship at a high speed during the battery swap process. The base station guides the ship to make a slight adjustment of the position according to the real-time updated position of the UWB tag on the ship, so as to eliminate the influence of the water flow and the wind direction on the ship, so that the ship deviates from the battery swap position and affects the battery swap process.

[0073] The application also includes: the battery swap station control system detects that the power capacity or the external power is insufficient, monitors the overall power information of each battery box, and controls the battery box with lower overall power to discharge to supply power to the battery box with higher overall power, so as to meet the power supply request of the ship.

[0074] Figure 2 It is a schematic diagram of a battery box management system of a ship provided by the application, as Figure 2As shown, the battery intelligent management terminal in the first battery box is used for sending the real-time acquired power information and state information of each battery pack in the first battery box to the battery intelligent management platform, so that the battery intelligent management platform judges whether the first battery box can continue to supply power to the ship according to the power information and state information of each battery pack in the first battery box, and according to the power-off instruction, disconnects the power supply switch of the first battery box, and stops the first battery box from supplying power to the ship; the battery intelligent management platform is used for sending a power-off instruction to the battery intelligent management terminal in the first battery box when judging that the first battery box cannot continue to supply power to the ship, and simultaneously sending a power-on instruction to the battery intelligent management terminal in the second battery box; and the battery intelligent management terminal in the second battery box is used for closing the power supply switch of the second battery box according to the power-on instruction, so that the second battery box supplies power to the ship.

[0075] The embodiment of the application provides an electronic device, including: a memory; a processor; and a computer program; wherein the computer program is stored in the memory and is configured to be executed by the processor to realize a battery box management method of a ship.

[0076] The embodiment of the application provides a computer readable storage medium, which has a computer program stored thereon; the computer program is executed by a processor to realize a battery box management method of a ship.

[0077] The embodiment of the application provides a battery box management method of a ship, including:

[0078] S1, the battery intelligent management terminal collects the marine battery monomer voltage, monomer current, monomer temperature, extreme voltage, extreme temperature and extreme current through a CAN communication mode, and performs data processing and operation according to an existing battery model and algorithm to balance the internal power supply voltage and current of the battery and achieve load balancing.

[0087] Operating voltage: 9V - 36V

[0088] Signal transmission center frequency: 2.4 GHz

[0089] Protection level: IP67

[0090] 1.1, the battery intelligent management terminal is integrated into the battery of the battery replacement ship, and the battery position and asset scheduling and management are monitored, optimized, positioned and tracked at any time. The battery used by the ship is a large-capacity container battery (capacity is 2000kWh, nominal voltage is above 600V, and standard current is 1000A).

[0091] 1.2, the battery management terminal adopts a classic hardware architecture of a large core (MPU) plus a small core (MCU), so that the device operation is stable. The software logic makes the large core handle business and the small core controls the device, effectively reducing the device power consumption and speeding up the business processing speed, which can quickly and accurately obtain a large amount of battery data information.

[0092] 1.3, the battery management terminal can actively select the use of battery packs, clusters and cells according to the alarm information in the battery box, and turn off and enable the use of other battery packs. If more than a certain proportion of battery packs in the entire battery box have a temperature that is too high, a single difference that is too large, etc. The third level alarm will actively disconnect the container battery power supply and switch to another two battery boxes for power supply.

[0093] S2, after the battery intelligent management terminal obtains the detailed parameters and detailed location information of the battery replacement ship battery, it transmits the relevant information to the intelligent management platform through the built-in 4G data transmission module and the 4G network. Due to the large size of the battery and the large capacity of the battery, a large amount of battery data is collected and a large amount of data is stored in a unit of time, which poses a great challenge to the processor and collection speed of the battery intelligent management terminal.

[0094] S3, after the intelligent management platform obtains the detailed data uploaded by the battery intelligent management terminal, the data transmission adopts a national special data format and transmission protocol for data platform upload. The platform end analyzes the power consumption of the ship, suggests the ship's sailing speed and direction, and plays back the ship's driving path according to the positioning information. Make the ship path control throughout the whole process.

[0095] S4, the intelligent management platform has the functions of remote positioning and control of the battery replacement ship battery through the battery intelligent management terminal, limiting the ship driving, limiting the battery power output, and remotely limiting the ship driving speed.

[0096] 4.1, through the authentication and encryption scheme of the battery intelligent management terminal and the battery replacement ship battery, the management platform and the battery replacement ship battery information are safely and efficiently interacted.

[0097] 4.2, the relevant content of the authentication encryption scheme can effectively control the power output of the battery, and then control the driving speed of the ship.

[0098] 4.2, the driving control of the management platform can control the direction and speed of the ship according to the accurate chart.

[0102] 2) The marine battery replacement battery has the characteristics of large capacity and high density. The data generated by the massive battery cells in the battery due to the increase of capacity is acquired and analyzed to solve the problem that the life of the whole battery replacement battery of the ship is reduced due to the temperature, voltage and current of the single battery, and the life of the battery is prolonged.

[0103] 3) The battery environment used in the ship is relatively poor. The humidity and temperature during the whole year will seriously corrode the related parts of the battery.
