[0031] Embodiments of this application are described below with reference to the accompanying drawings, such as Figure 1 and Figure 2As shown in the figure, the ship-engine energy storage intelligent control power system of this application embodiment is used to supply power to the ship 10 and the aircraft 20. The system includes: a photovoltaic power generation and energy storage system 1, a diesel power generation system 2, and an electric energy dispatching module 3. The photovoltaic power generation and energy storage system 1 includes photovoltaic panels 11 laid on the platform of the ship 10 and multiple battery packs 12 installed in the ship 10. The photovoltaic panels 11 are used to provide a first amount of electricity, and the battery packs 12 are used to store the first amount of electricity. The diesel power generation system 2 includes a diesel generator set 21 and an electric energy management module 22. The diesel generator set 21 is used to drive the generator to generate a second amount of electricity. The electric energy dispatching module 3 is communicatively connected to the battery packs 12 and the electric energy management module 22 (indicated by the dotted line in the figure). It is used to dynamically adjust the power supply ratio between the first amount of electricity and the second amount of electricity according to different power consumption conditions to supply power to various target systems, including the ship propulsion system 100, the aircraft power supply system 200, and the multiple battery packs 12.

[0032] Specifically, the photovoltaic panel 11 consists of multiple photovoltaic matrices arranged in an array in an open area of ​​the deck of the ship 10. It can efficiently capture sunlight and convert it into electrical energy. For example, the photovoltaic panel 11 can be installed on the top surface of the platform structure of the ship 10 to maximize the area for receiving sunlight. Each photovoltaic matrix is ​​independently connected to a combiner box, and then the electrical energy is transmitted to the battery pack 12 for storage via a DC power distribution cabinet. Subsequently, it provides a stable DC power supply for the ship's propulsion system 100 and the aircraft power supply system 200.

[0033] Photovoltaic panel 11 uses high-efficiency monocrystalline silicon material, which has the characteristics of resisting salt spray corrosion and is suitable for complex marine environments.

[0034] In one embodiment, photovoltaic panels 11 are installed on a landing platform in the middle of the ship 10 for landing the aircraft 20, achieving both energy harvesting and aircraft take-off and landing functions, thus improving space utilization efficiency. The photovoltaic panels on the surface of the landing platform are covered with light-transmitting reinforced glass, balancing structural strength and photoelectric conversion efficiency, and can withstand instantaneous impact loads during aircraft take-off and landing.

[0035] In clear weather conditions, the photovoltaic panel 11 supplies power to the aircraft power supply system 200 and the ship power system 100, enabling the priority use of green energy, thereby reducing fuel consumption and carbon emissions, and ensuring a continuous and stable energy supply for ships and aircraft.

[0036] like Figure 1 As shown in the illustration, the aircraft in this embodiment is an electric vertical takeoff and landing (VTOL) aircraft, capable of vertical takeoff and precise landing on a limited-area platform while carrying passengers, and adaptable to complex weather conditions at sea. However, it is understood that the aircraft in this embodiment could also be other types of VTOL aircraft, and no specific limitations are imposed in this application.

[0037] like Figure 3 As shown, the battery pack 12 includes a power management system (BMS) 121 and a battery module 122. The battery module 122 is composed of multiple high-energy-density lithium iron phosphate battery cells connected in series, which has high energy density and long cycle life. The power management system 121 monitors the voltage, current and temperature parameters of the battery module 122 in real time to ensure that the charging and discharging process is safe and controllable.

[0038] Furthermore, the battery pack 12 is also connected to the AC power grid of the ship 10 via a bidirectional inverter, which can supply the loads on board and realize flexible scheduling and feedback of electrical energy.

[0039] It should be added that there is no specific limit to the number of battery packs 12.

[0040] like Figure 4 As shown, the diesel generator system 2 consists of a diesel generator set 21 and an electrical energy management module 22. The diesel generator set 21 adopts high-pressure common rail electronic injection technology, featuring low fuel consumption, low emissions, and high reliability, and can stably start and operate in ambient temperatures ranging from -20℃ to 50℃. The electrical energy management module 22 integrates the operating status monitoring and power output regulation functions of the diesel generator set 21.

[0041] The ship's power system 100 includes an electric propulsion system, which comprises an electric motor, a drive shaft, and a controllable pitch propeller. Electric power drives the motor to rotate the propeller, enabling the ship to move forward, backward, and adjust its speed. The electric propulsion system utilizes electricity allocated from either the first or second power source to achieve all-electric propulsion, significantly reducing reliance on traditional internal combustion engines and enabling zero-emission operation during near-shore cruising or port operations.

[0042] The aircraft power supply system 200 provides the electrical energy required for the aircraft 20 to start, cruise, and charge. It is physically and electrically connected to the battery pack 12 via a quick-connect interface, supporting automatic docking and disconnection. The power supply system may have a built-in energy management unit that can predict energy consumption based on flight mission planning and dynamically adjust the charging power.

[0043] The power dispatch module 3 dynamically adjusts the power supply ratio between the first power supply and the second power supply according to different power consumption conditions.

[0044] Different power consumption conditions include light intensity, load demand, and battery pack state of charge. The power dispatch module 3 dynamically adjusts the output ratio of the first power supply and the second power supply based on the real-time monitored power consumption of the ship 10 and the aircraft 20, combined with the photovoltaic power generation status and the remaining power of the battery pack 12.

[0045] Specifically, the power dispatch module 3 includes a calculation module 31 and a control module 32. The calculation module 31 is responsible for collecting real-time operating data of the photovoltaic array, battery pack and diesel generator set, and performing energy supply and demand analysis in conjunction with the navigation plan and weather forecast to generate the optimal dispatch strategy. The control module 32 executes instructions according to the strategy to dynamically control the power allocation values ​​of the first power and the second power.

[0046] During the day, solar energy is converted into electrical energy. The first amount of electricity generated is prioritized for use by the ship's power system 100 and the aircraft's power supply system 200. The excess electricity is then controlled by the power scheduling module 3 and stored in the battery pack 12.

[0047] In one embodiment, under continuously changing lighting conditions, the calculation module 31 updates the prediction model every 15 minutes, combining satellite meteorological data and ship navigation paths to accurately predict the lighting output curve for the next 6 hours. Based on this photovoltaic output curve, the control module 32 sets the depth of discharge and charging rate of the battery pack 12 to avoid lifespan degradation caused by overcharging and discharging.

[0048] When sunlight is insufficient or electricity demand increases, the power dispatch module 3 automatically starts the diesel generator set 21 to supplement power and dynamically allocates secondary power according to the real-time load to ensure the continuous and stable operation of critical systems. The entire power system can achieve efficient utilization of green energy and seamless switching between emergency power supply through intelligent collaborative control based on navigation missions, aircraft take-off and landing frequencies, and weather conditions, thereby improving the reliability and economy of integrated ship-machine energy management.

[0049] Taking the aircraft charging scenario as an example, when the aircraft 20 lands and connects to the aircraft power supply system 200, it automatically starts the fast charging mode, prioritizing the use of the first power source for power supply, and supplementing the insufficient part with the second power source provided by the diesel generator system.

[0050] The output of diesel generator system 2 is rectified and regulated before being connected to the power dispatch module 3, forming a multi-source complementary power supply architecture with the photovoltaic energy storage system. The unit is equipped with an intelligent start-stop control unit, which automatically switches on and off according to the state of charge of battery pack 12 and load power demand, avoiding no-load operation and improving fuel efficiency.

[0051] At night or in rainy weather, when the photovoltaic power generation is lower than the system's base load, the power dispatch module 3 completes the grid connection of the diesel generator set within 300 milliseconds to ensure uninterrupted operation of the ship's power system 100 and the aircraft's power supply system 200.

[0052] When the state of charge of battery pack 21 is lower than the preset threshold, the power dispatch module 3 prioritizes the diesel generator system 2 to charge battery pack 12, and at the same time coordinates the photovoltaic power generation and energy storage system 1 to supply power in parallel with the diesel generator system 2 to ensure the stable operation of the ship power system 100 and the aircraft power supply system 200.

[0053] When the aircraft 20 experiences a momentary high power demand during takeoff and landing, the power dispatch module 3 can coordinate the rapid discharge of the battery pack 12 to meet the load peak and ensure a stable and reliable power supply.

[0054] Meanwhile, the power dispatch module 3 has an intelligent prediction function, which can predict the trend of light intensity changes based on historical data and meteorological information, and adjust the starting strategy of the diesel generator set 21 and the charging and discharging plan of the battery pack 12 in advance. For example, if it is predicted that the light intensity will weaken in the later stage, the power dispatch module 3 will start the diesel generator set 21 in advance for hot standby and increase the reserve power of the battery pack 12 to ensure seamless switching of power sources when the light intensity weakens.

[0055] Furthermore, the system supports remote monitoring and upgrades, transmitting operational status to the shore-based control center in real time via a wireless communication interface, facilitating dynamic optimization of energy configuration by maintenance personnel. The entire power system achieves a deep integration of efficient utilization of green energy and flexible replenishment of traditional energy, significantly improving the endurance and power supply security of collaborative operations between ships and aircraft.

[0056] When the system detects a sudden load change or power switch, the control module 32 of the power dispatch module 3 immediately activates a rapid response mechanism, prioritizing the use of battery pack 12 for instantaneous power compensation to avoid power outages. Simultaneously, the calculation module 31 continuously tracks the diesel generator set's operating efficiency curve and adjusts its output power to the economic range as needed, reducing fuel consumption and carbon emissions. The entire dispatch process requires no manual intervention, achieving autonomous operation around the clock.

[0057] In one embodiment, the power system also includes a public grid interface 4 for connecting to the public grid to charge the battery pack. When docked at a port, the system automatically switches to shore power mode, connecting to shore power through the public grid interface 4 to achieve zero-emission charging. At this time, the power dispatch module 3 prioritizes using the public grid to charge the battery pack 12 with constant current and constant voltage, while simultaneously supplying power to the auxiliary equipment of the ship 10 and the aircraft 20. During charging, the system monitors the battery temperature and voltage status in real time to prevent overcharging or thermal runaway risks. The public grid interface supports plug-and-play and authentication functions to ensure power safety and accurate billing. This design further expands energy replenishment pathways and improves the economy and environmental friendliness of the entire lifecycle operation.

[0058] Once the vessel departs from port, the system automatically disconnects from shore power and switches to autonomous power supply mode, seamlessly transitioning to a combined operation of diesel generators and energy storage. The power dispatch module optimizes energy efficiency distribution throughout the voyage based on preset energy strategies according to the voyage plan.

[0059] This application embodiment uses a diesel generator set, a lithium iron phosphate power battery pack, and a photovoltaic power generation system as the power source for the ship's propulsion system and the aircraft's power supply system, maximizing the use of solar energy. When using solar energy and the power battery pack alone, zero emissions of pollutants are achieved. When using a diesel generator set, the power battery pack can serve as a temporary load under certain circumstances to regulate the ship's power demand, allowing the diesel generator set to operate in the economic fuel consumption range, thereby reducing fuel consumption and pollutant emissions.

[0060] The embodiments of this application overcome the problems of insufficient long-range driving range of a single power battery pack, serious pollution problems of a single diesel generator set power source, and insufficient continuous operation at high speeds of a single solar power source, achieving the technical effect of being both energy-saving and environmentally friendly with unlimited driving range.

[0061] The above embodiments are merely illustrative of the principles and effects of this application. Any person skilled in the art can modify or alter the above embodiments without departing from the purpose of this application. Therefore, all equivalent modifications or alterations made by those skilled in the art without departing from the purpose disclosed in this application should still be covered by the claims of this application.
