Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments of the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0038] The charging and swapping control method for an electric ship provided in an embodiment of the present application can be applied to a charging and swapping control system for an electric ship, the system comprising: a battery swap station cloud platform, multiple electric ships and multiple battery swap stations; and communication connections between the battery swap station cloud platform and the electric ships and battery swap stations.

[0039] The battery swap station cloud platform is used to receive charging and battery swap requests from electric ships and dispatch the power resources of the battery swap station;

[0040] Multiple electric ships are used to send charging and battery swapping requests to the battery swapping station cloud platform;

[0041] Multiple battery swap stations, including charging ports and supply vessels, are used to charge and swap batteries for electric ships.

[0042] In the embodiment of the present application, the battery swap station cloud platform pre-stores the communication address and unique identifier of the display terminal of each electric vessel, as well as the contact information of each electric vessel owner, and can communicate with the display terminal and the electric vessel owner.

[0043] The preferred embodiments of the present application are described below in conjunction with the drawings in the specification. It should be understood that the preferred embodiments described herein are only used to illustrate and explain the present application, and are not used to limit the present application. In addition, the embodiments and features in the embodiments of the present application may be combined with each other if there is no conflict.

[0044] Figure 1 The present invention provides a flow chart of a method for controlling the charging and switching of an electric ship. Figure 1 As shown, the method may include:

[0045] Step S110: in response to a charging / swapping request sent by the electric ship, multiple charging / swapping modes are sent to the electric ship; and a target charging / swapping mode selected by the electric ship from the multiple charging / swapping modes is obtained.

[0046] In an embodiment of the present application, the electric ship can send charging and battery swapping requirements to the battery swap station cloud platform according to its own needs.

[0047] In an embodiment of the present application, before responding to the charging and swapping request sent by the electric ship, the battery swap station cloud platform monitors the real-time power of each electric ship in real time. When the real-time power of any electric ship is lower than a preset power warning threshold, the battery swap station cloud platform sends a power warning to the corresponding electric ship; specifically, the battery swap station cloud platform can send a text message to the mobile terminal of the owner of the electric ship, or send a warning prompt to the display terminal of the electric ship.

[0048] In an embodiment of the present application, the charging and swapping request includes: the real-time power demand, target power demand, current position, speed, direction of travel, wet surface area and total weight (including the weight of the hull itself and the load) of the electric ship; specifically, the target power demand can be set by the user, or determined by the real-time power demand and the power upper limit.

[0049] In an embodiment of the present application, after receiving the charging and swapping request sent by the electric ship, the battery swapping station cloud platform matches the parameters of the electric ship from a pre-configured electric ship parameter table according to the unique code of the electric ship that sent the charging and swapping request. The parameters of the electric ship include: the model of the electric ship, the model of the battery, the capacity of the battery, the voltage of the battery, the battery charging method and the corresponding charging time, the total propulsion efficiency and the drag coefficient; specifically, the battery charging method includes fast charging and / or slow charging.

[0050] In the embodiment of the present application, after obtaining the above-mentioned matching data, the battery swap station cloud platform will send the matched data to the display terminal of the electric ship and the mobile terminal of the electric ship owner so that the electric ship can confirm the information. When the electric ship confirms that the corresponding data is correct, it will send a confirmation message to the battery swap station cloud platform. When the battery swap station cloud platform receives the confirmation message, it will generate a charging and swapping order.

[0051] In another embodiment of the present application, the charging and battery swapping request sent by the electric ship may not include the current location of the electric ship. When the electric ship sends a confirmation message to the battery swap station cloud platform, it also sends its current location to the battery swap station cloud platform.

[0052] In the embodiments of the present application, the charging and swapping methods include: charging and swapping on a supply ship and charging and swapping at a battery swapping station; specifically, high-speed charging and swapping on a supply ship, medium-speed charging and swapping on a supply ship, and low-speed charging and swapping on a supply ship.

[0053] In another embodiment of the present application, the above-mentioned charging and battery swapping methods can be further refined into slow charging and fast charging. For example, charging and battery swapping at battery swap stations can be refined into slow charging and battery swapping at battery swap stations and fast charging and battery swapping at battery swap stations; slow charging and battery swapping at supply ships and low-speed fast charging and battery swapping at supply ships.

[0054] In an embodiment of the present application, while sending multiple charging and swapping methods to the electric ship, charging and swapping information corresponding to the different charging and swapping methods will also be sent to the electric ship; when the charging and swapping method is charging and swapping at a battery swapping station, the charging and swapping information includes: the locations of multiple battery swapping stations whose distance from the current location does not exceed the configured distance threshold, and the charging and swapping cost data, waiting time, and estimated charging end time of different battery swapping stations; when the charging and swapping method is charging and swapping by a supply ship, the charging and swapping information includes: the estimated charging and swapping time and the corresponding charging and swapping cost data.

[0055] The user can select a charging method from the multiple charging methods sent according to his own needs, based on the different charging methods and corresponding charging information received, which is the target charging method.

[0056] In another embodiment of the present application, when sending the charging and swapping method, the battery swap station cloud platform needs to call all currently available charging and swapping resources, including the available power, power billing standards and charging methods of each battery swap station, and the charging efficiency corresponding to different charging methods, the location of the supply boats owned by each battery swap station, the available power and charging methods, etc.

[0057] The battery swap station cloud platform generates charging and swapping information for different charging and swapping methods by analyzing the currently available charging and swapping resources, charging and swapping requests and the corresponding electric ship parameters.

[0058] In the embodiment of the present application, the generation of charging and swapping information of the charging and swapping mode of the battery swapping station includes:

[0059] Obtain the charging methods supported by different battery swap stations, the charging efficiency corresponding to different charging methods, the location of the battery swap station, the parameters of the electric ship, the charging and swapping request, and the water environment data where the battery swap station is located and the current location of the electric ship;

[0060] Based on the location of each battery swap station and the current location and travel direction of the electric ship, determine the distance between each battery swap station located in front of the electric ship in the travel direction and the electric ship; for any battery swap station located in front of the electric ship in the travel direction, determine the optimal path for the electric ship to the battery swap station based on the location of the battery swap station, the current location of the electric ship and the water environment data; based on the optimal path, the speed of the electric ship, the water flow speed, the relative position of the electric ship and the battery swap station, and the direction of the water flow, determine the estimated sailing time for the electric ship to reach the battery swap station at the current speed; based on the current location of the electric ship, match the type of water resources at the current location from the configured water resource location and type comparison table; based on the type of water resources, determine the density of water resources;

[0061] The resistance and propulsion efficiency of the electric ship are calculated based on the resistance coefficient of the electric ship, the density of water resources, the wet surface area and the speed. The actual electric energy consumption power of the electric ship is calculated according to the propulsion efficiency and the total propulsion efficiency. The initial power consumption of the electric ship along the optimal path to the battery swap station is determined based on the estimated sailing time and the actual electric energy consumption power. The difference between the real-time power of the electric ship and the initial power consumption is used as the power difference. The difference between the power difference and the target demand power is used as the target charging power. The target grid power consumed by different charging methods is calculated by taking the ratio of the target charging power to the charging efficiency corresponding to different charging methods. The product of the power billing standard and the target grid power consumed by different charging methods is used as the charging and swapping cost data required for different charging methods of the battery swap station.

[0062] In the embodiment of the present application, the types of water resources include fresh water resources and sea water resources.

[0063] In the embodiment of the present application, the front of the electric ship's traveling direction includes not only the front, but also the side front or the front part; the front of the electric ship's traveling direction can be determined according to the configured search radiation range and the current position of the electric ship. The search radiation range of the electric ship can be customized by the user or preset by the battery swap station cloud platform.

[0064] In another embodiment of the present application, the generation of charging and swapping information of the charging and swapping mode of the battery swapping station further includes:

[0065] Obtain the occupancy status of the charging ports of the battery swap station; subtract the expected sailing time from the expected occupancy time to obtain the waiting time of the electric ship; calculate the expected end time of charging based on the waiting time, target charging power and charging efficiency of different charging methods.

[0066] In the embodiment of the present application, the occupancy status includes the current occupancy status and the estimated occupancy time; the charging port is a charging port corresponding to different charging methods.

[0067] In an embodiment of the present application, the water environment data includes water flow speed, wind direction changes, weather conditions, as well as dangerous areas in the water area, prohibited areas, and risky waterways that exceed risk thresholds.

[0068] In an embodiment of the present application, based on the location of the battery swap station, the current location of the electric ship and water environment data, determining the optimal path for the electric ship to the battery swap station includes:

[0069] Based on the moving distance, moving time, energy consumption and safety risk rating of the electric ship to the battery swap station, a comprehensive cost function is constructed; based on the water environment data, a graph model of the water area is constructed; specifically, the water area is divided into multiple small cells or nodes, each node represents a possible path point; a connection relationship is established: the connection relationship between nodes is defined to obtain a graph model of the water area; the current position of the electric ship is taken as the starting point and the position of the battery swap station is taken as the end point, and multiple feasible paths are calculated; the path planning algorithm is used to select the optimal path from multiple feasible paths based on the graph model and the comprehensive cost function.

[0070] In the embodiment of the present application, the safety risk rating is obtained by analyzing the risks posed to the electric vessel by passing through dangerous areas and risky waterways during movement.

[0071] In an embodiment of the present application, the estimated charging and swapping time includes an estimated charging and swapping start time and an estimated charging and swapping end time.

[0072] In the embodiment of the present application, the generation of charging and swapping information of the supply ship charging and swapping mode includes:

[0073] Obtain the location, available power and charging and swapping methods of the supply boats owned by different battery swap stations;

[0074] Select a supply boat with available power greater than the target power demand of the electric ship from the supply boats owned by different battery swap stations to obtain a first target supply boat;

[0075] For any first target supply boat, based on the boat position of the first target supply boat, the current position of the electric ship, the forward direction (or forward path) and the water environment data of the corresponding water area, the optimal path for each first target supply boat to catch up with the electric ship is determined;

[0076] Based on the speed of the electric ship, determine the speed of the supply boat under different supply ship charging methods; specifically, the supply ship high-speed charging and battery replacement, the supply ship medium-speed charging and battery replacement, and the supply ship low-speed charging and battery replacement correspond to different ship speeds respectively;

[0077] Based on the optimal path of each first target supply boat to catch up with the electric ship, different supply ship charging methods, the speed of the supply boat under the corresponding supply ship charging method, the position and forward direction of the electric ship, the time for the supply boat to catch up with the electric ship under different supply ship charging methods is determined as the estimated charging and battery replacement start time;

[0078] According to the estimated charging and swapping start time, the charging and swapping methods supported by the supply boat and the corresponding charging and swapping times, the estimated charging and swapping end time of the charging and swapping methods supported by the supply boat is determined.

[0079] In the embodiment of the present application, based on the speed of the electric ship, determining the speed of the supply boat under different supply ship charging modes includes:

[0080] The speed of the supply ship during medium-speed charging and battery replacement is close to that of the electric ship, so the electric ship can continue to move forward, and when the supply ship is during medium-speed charging and battery replacement, the supply ship will inevitably catch up with the electric ship before the electric ship runs out of power;

[0081] The speed of the supply ship during high-speed charging and battery replacement is greater than that of the supply ship during medium-speed charging and battery replacement. The electric ship can continue to move forward. When the supply ship is charging and battery replacement at high speed, the supply ship catches up with the electric ship at the fastest speed.

[0082] When the supply ship is charging and replacing batteries at a low speed, the electric ship cannot continue to move forward and needs to stay where it is and wait for the supply ship.

[0083] In the embodiment of the present application, in view of the different ship speeds of different supply ship charging methods, which will affect whether the electric ship moves forward, the estimated charging and swapping time under different methods is not the same; when the supply ship needs to catch up with the electric ship, the estimated charging and swapping time should take into account the speed difference between the ship speed and the electric ship speed.

[0084] In an embodiment of the present application, the charging and swapping methods supported by the supply boat and the corresponding charging and swapping costs can be determined by data such as power consumption or battery wear and tear. The charging and swapping methods supported by the supply boat and the corresponding charging and swapping costs are pre-stored in a configured charging and swapping method and cost comparison table and can be directly matched.

[0085] In an embodiment of the present application, after receiving different charging and swapping methods and corresponding charging and swapping information, the user can select one charging and swapping method according to his or her own needs and considerations to obtain a target charging and swapping method.

[0086] Step S120: Based on the target charging / swapping mode and the charging / swapping request, determine the target charging / swapping equipment and the scheduling information for scheduling the target charging / swapping equipment.

[0087] In an embodiment of the present application, when the user selects a target charging and swapping mode, the location of the electric ship and the corresponding resource data of the battery swapping station and supply ship may change. Therefore, the target charging and swapping information corresponding to the target charging and swapping mode can be updated, and the corresponding optimal path and / or speed data can be extracted to obtain scheduling information; the optimal path can also be re-planned based on real-time electric ship location, battery swapping station location or boat location, water environment data, and other data, and scheduling information can be generated.

[0088] In an embodiment of the present application, when the battery swapping mode at a battery swap station is selected, the scheduling information actually reserves a charging port and the corresponding grid power for the electric ship; when the battery swapping mode is selected for a supply ship, the ship speed and pursuit path of the supply ship are controlled.

[0089] In another embodiment of the present application, if the available power of the supply ship closest to the electric boat is insufficient to support the target power demand, the target power demand can be met by replacing or charging the supply ship, thereby saving user time.

[0090] In another embodiment of the present application, if the available power of the supply ship closest to the electric ship is insufficient to support the target power demand, the available power information of the supply ship can also be sent to the user, asking the user whether to call the available power of the supply ship first, and giving the cost required to call the available power, thereby realizing power replenishment for the electric ship with the minimum economic cost and the minimum time spent.

[0091] In the embodiment of the present application, when the charging and swapping mode is charging and swapping at a battery swapping station, the target charging and swapping equipment is determined based on the target charging and swapping mode and the charging and swapping request, including:

[0092] From multiple battery swap stations, select the battery swap station that is closest to the current location and ahead of the current location in the direction of travel as the target charging and swapping equipment.

[0093] In the embodiment of the present application, when the charging and swapping mode is supply ship charging and swapping, based on the target charging and swapping mode and the charging and swapping request, the target charging and swapping equipment and the scheduling information for scheduling the target charging and swapping equipment are determined, including:

[0094] A plurality of initial target supply ships having remaining power greater than a target power requirement are selected from a plurality of supply ships; a target supply ship is selected from the plurality of initial target supply ships according to the current position, the direction of travel and the position of each initial target supply ship, and the target supply ship is used as a target charging and swapping device; scheduling information is generated based on the target charging and swapping mode, the real-time power, the speed and the position of the target supply ship; specifically, the scheduling information includes: the moving speed and the moving path of the target supply ship.

[0095] Step S130: Based on the scheduling information, control the target charging and swapping equipment to charge and swap the electric ship.

[0096] In an embodiment of the present application, when the scheduling information is generated, the battery swap station or supply ship will be controlled to charge and swap the electric ship.

[0097] In an embodiment of the present application, during the process of charging and replacing batteries for an electric ship at a battery replacement station or a supply ship, the electric ship display terminal and the mobile terminal of the electric ship owner can query the battery replacement status in real time; when the battery replacement is completed, information on the completion of the battery replacement and the corresponding fees will also be sent.

[0098] In an embodiment of the present application, after the supply ship charges and exchanges battery for the electric boat, the battery swap station cloud platform will generate a return path for the supply ship and control the supply ship to return to the battery swap station.

[0099] In another embodiment of the present application, the battery swap station cloud platform can also analyze the charging and swapping conditions of each battery swap station and the charging and swapping routes of each supply ship, analyze the resource demand and existing resource amount of each battery swap station, so as to regulate the power resources of different battery swap stations and realize efficient resource utilization; for example, the supply ship of a battery swap station that rarely dispatches a supply ship can be deployed to other battery swap stations.

[0100] In another embodiment of the present application, a charging and battery replacement control method for an electric ship includes:

[0101] The battery swapping base station detects the battery power information of the customer's ship through the battery swapping station cloud platform; when the battery power of the current pure electric ship is detected to be too low, the customer is prompted via mobile phone text messages and the battery swapping station cloud platform; at the same time, the customer can also initiate a battery replacement request (i.e. a charging and battery swapping request) to the battery swapping station cloud platform;

[0102] The battery swap station cloud platform verifies the ship information after accepting the customer's order; the battery swap station cloud platform accepts the customer's order and positioning information; first, it informs the customer whether it is necessary to use a mobile battery swap boat to go to the destination to replace the battery; if no, it pushes the nearest battery swap station and the cost of each kilowatt-hour of electricity at each station; when the route is determined, the battery swap station will push the best route to the customer's ship in advance. After receiving the route, the customer's ship will save the route to the local end in advance to prevent network disconnection, and update it when there is network. During this process, the customer's ship repeatedly compares the local traffic flow with the last traffic flow. When it is determined that the network is indeed poor, the route is saved locally.

[0103] If you select yes, the battery swap station cloud platform will calculate the nearest battery swap station based on the current customer's running trajectory, and push three battery swap modes: high-efficiency, standard and economical;

[0104] Highly efficient, it calculates the speed of the supply ship based on the customer's current battery power information, and generates a pursuit track and time. The customer can check the time and distance of the supply ship's arrival at any time.

[0105] Standard type calculates the speed of the supply ship based on the customer's current battery power information, sends the customer's ship position information to the supply ship, and generates information such as the estimated arrival time and distance.

[0106] Economical type, calculates the required ship based on the remaining power of the customer's current ship and generates the arrival time.

[0107] Match the corresponding type of ship according to the customer's selection; send the order demand to the supply station, and upload the track route to the cloud platform of the battery swap station; the customer can check the real-time location and estimated arrival time of the supply ship through the mobile phone or ship interface; when the supply ship arrives at the customer's target location, check the battery swap status through the mobile phone;

[0108] After completing the battery swap, the supply ship sends the battery swap completion information to the battery swap station cloud platform; the best return route is generated, and the supply ship returns to the supply station. When the supply boat has a large number of battery modules left after replacing the previous order, it can supply nearby ships with insufficient power; the track route is generated according to the order location given by the platform, and the supply ship follows the track to reach the client, complete the battery swap, and generate the best return route, and the supply ship returns to the supply station.

[0109] Corresponding to the above method, the embodiment of the present application also provides a charging and swapping control device for an electric ship, such as Figure 2 As shown, the charging and switching control device of the electric ship includes:

[0110] A response unit 210 is used to respond to a charging and swapping request sent by the electric ship and send multiple charging and swapping modes to the electric ship;

Therefore, the specific working process and beneficial effects of each unit in the charging and swapping control device for an electric ship provided in the embodiments of the present application will not be repeated here.
