Description

Technical Field

[0001] This application relates to the field of microgrid technology, and in particular to an off-grid integrated photovoltaic-storage-diesel-charging device. Background Technology

[0002] With the continuous advancement of renewable energy technologies and the booming development of the new energy vehicle industry, the application of photovoltaic power generation, energy storage technology, and charging piles in microgrid systems has become increasingly common. The integrated use of these technologies provides strong support for the stable operation of the power grid and the popularization of new energy vehicles. However, in some areas not connected to the public power grid, such as remote islands, vast pastoral areas, border regions, and areas with weak power grid infrastructure, the application of photovoltaic-energy storage-charging microgrids is significantly limited. This situation also restricts the promotion and popularization of new energy vehicles in these areas.

[0003] While off-grid photovoltaic-storage-charging systems can address the charging challenges of new energy vehicles to some extent, the intermittent and unpredictable nature of renewable energy sources such as solar and wind power still poses significant challenges to the stability and reliability of microgrid systems. These challenges include, but are not limited to, discontinuous power supply, limitations in energy storage, and energy shortages under extreme weather conditions. Therefore, to ensure the effective operation of new energy vehicles in these special regions, further research and development of more efficient, stable, and reliable off-grid photovoltaic-storage-charging systems are needed. Utility Model Content

[0004] This application provides an off-grid integrated photovoltaic-storage-diesel-charging device, which aims to solve the problem of unstable power supply in existing off-grid photovoltaic-storage-charging systems.

[0005] To achieve the above objectives, this application proposes an off-grid integrated photovoltaic-storage-diesel-charging device. This off-grid integrated photovoltaic-storage-diesel-charging device includes a housing, photovoltaic modules mounted on the housing, and an energy storage cabinet, a diesel generator, and a charging pile mounted inside the housing.

[0006] The photovoltaic module is at least disposed on the top surface of the enclosure for collecting solar energy and converting it into electrical energy; the diesel generator is used to provide diesel power generation; the energy storage cabinet includes an energy management module and an energy storage module, the energy management module being electrically connected to the photovoltaic module, the diesel generator, the energy storage module, and the charging pile, for coordinating the energy input or output of the photovoltaic module, the energy storage module, and the diesel generator;

[0007] The box body is provided with unfolding panels on both long sides. When unfolded, the unfolding panels can at least expose the charging pile inside the box body, so as to charge the vehicle outside the box body through the charging pile.

[0008] In some embodiments, the enclosure is divided into different chambers along its length by partitions, for accommodating the energy storage cabinet, the diesel generator, and the charging pile, respectively.

[0009] In some embodiments, the housing is provided with an inspection door that connects to the end chambers, and each partition plate is provided with a connecting door, so that when the unfolded plate is in the retracted state, the user can enter each chamber through the inspection door and the connecting door to perform maintenance work.

[0010] In some embodiments, the bottom of the enclosure is provided with wiring grooves on both sides along its length, and wiring holes communicating with the wiring grooves are provided at the bottom of each chamber, so that wires can be run from the bottom of the enclosure through the wiring grooves and the wiring holes to electrically connect the diesel generator, the energy storage module and the charging pile.

[0011] In some embodiments, the unfolding plate occupies the entire wall of the long side of the box.

[0012] In some embodiments, the photovoltaic module is further disposed on the surface of the unfolding plate to unfold or retract with the unfolding plate.

[0013] In some embodiments, the unfolding angle of the unfolding plate is adjustable.

[0014] In some embodiments, the number of charging piles is arranged in two rows along the length direction in their respective chambers, with each row of charging piles facing an unfolding plate.

[0015] In some embodiments, the container is designed as a shipping container.

[0017] This application proposes an off-grid integrated photovoltaic-storage-diesel-charging device. The device includes a housing, photovoltaic modules mounted on the housing, and an energy storage cabinet, a diesel generator, and a charging pile housed within the housing. The photovoltaic modules are located at least on the top surface of the housing and are used to collect solar energy and convert it into electrical energy. The diesel generator provides diesel power. The energy storage cabinet includes an energy management module and an energy storage module. The energy management module is electrically connected to the photovoltaic modules, diesel generator, energy storage module, and charging pile, and coordinates the energy input or output of the photovoltaic modules, energy storage module, and diesel generator. The housing has unfolding panels on both long sides, which, when unfolded, at least expose the charging pile inside the housing, allowing charging of vehicles outside the housing via the charging pile. In this application, the energy management module coordinates the energy input or output of the photovoltaic modules, energy storage module, and diesel generator, enabling priority use of photovoltaic power generation and storage of excess energy during periods of sufficient sunlight; and priority use of the energy storage module during periods of insufficient sunlight, with the diesel generator activated only when necessary. Therefore, the off-grid integrated photovoltaic-storage-diesel-charging device proposed in this application can dynamically adjust the output of each energy source according to real-time power demand and energy status, ensuring that the charging pile can work stably under various energy conditions and meet the charging needs of vehicles.

[0025] See Figure 1 and Figure 2 As shown, this application proposes an off-grid integrated photovoltaic-storage-diesel-charging device 100. The off-grid integrated photovoltaic-storage-diesel-charging device 100 includes a housing 10, photovoltaic modules 20 mounted on the housing 10, and an energy storage cabinet 30, a diesel generator 40, and a charging pile 50 mounted inside the housing 10.

[0026] The photovoltaic modules 20 are installed at least on the top surface of the enclosure 10 to maximize the use of solar energy, converting solar energy into electrical energy. This energy is prioritized for powering the charging pile 50 or, when sufficient power is available, stores excess energy in the energy storage module. The energy storage cabinet 30 includes an energy storage module and an energy management module. The energy storage module (such as a lithium battery pack) stores excess energy generated by photovoltaic or diesel power generation. The energy management module intelligently allocates power, coordinating the input and output of the photovoltaic modules 20, the energy storage module, and the diesel generator 40. Specifically, it can store photovoltaic power during the day and release it at night to achieve peak shaving and valley filling; and when photovoltaic power is insufficient, it can call upon the energy storage module or start the diesel generator 40. The diesel generator 40 serves as a backup power source, starting when neither photovoltaic nor energy storage can meet the demand, ensuring continuous power supply. The charging pile 50 is located inside the enclosure 10 and is exposed through the unfolding panel 110 for easy vehicle charging.

[0027] In summary, this application provides a multi-energy complementary mechanism, with photovoltaic power, energy storage, and diesel generator 40 providing triple power supply protection to avoid power outages caused by a single energy source failure. The charging pile 50 can operate stably under various energy conditions, meeting the vehicle's charging needs.

[0028] Furthermore, both long sides of the housing 10 are provided with unfolding panels 110. When unfolded, the unfolding panels 110 can at least expose the charging pile 50 inside the housing 10. Thus, the charging pile 50 is integrated into the housing 10. After unfolding the panels 110, the charging pile 50 can be exposed, eliminating the need for additional charging facilities and further adapting to temporary or mobile scenarios (such as construction sites or temporary camps).

[0029] See Figure 1 As shown, in some embodiments, the housing 10 is divided into different chambers along its length by a partition plate 111, for accommodating the energy storage cabinet 30, the diesel generator 40, and the charging pile 50, respectively.

[0030] In this embodiment, the interior of the enclosure 10 is divided into three independent chambers: energy storage cabinet 30, diesel generator 40, and charging pile 50, by means of the isolation plate 111. This achieves spatial partitioning and functional isolation, which can avoid electromagnetic interference and thermal coupling between the equipment, thereby improving safety and reducing the risk of fire or explosion.

[0031] Each chamber can be designed with an independent ventilation system (such as air inlet and air outlet) to optimize the heat dissipation requirements of different devices (only for the case where the unfolding plate 110 is set up with the charging pile 50; other chambers are not enclosed spaces and are waterproof and dustproof).

[0032] See Figure 1 As shown, in some embodiments, the housing 10 is provided with an inspection door 112 that connects to the end chamber, and each partition plate 111 is provided with a connecting door, so that when the unfolded plate 110 is in the retracted state, the user can enter each chamber through the inspection door 112 and the connecting door to perform maintenance work.

[0033] In this embodiment, at least one end of the housing 10 is provided with an inspection door 112, which provides direct access to the end chamber, enabling rapid inspection and maintenance of large equipment such as the diesel generator 40. Furthermore, connecting doors are provided on each partition plate 111 to form a transverse inspection passage, facilitating user movement between different chambers for cross-regional maintenance. This avoids the inconvenience of needing to drive the unfolding plate 110 for maintenance, thus improving maintenance efficiency.

[0034] Furthermore, the bottom of the enclosure 10 has wiring channels (not shown in the attached diagram) on both sides along its length, and wiring holes connecting the wiring channels are provided at the bottom of each chamber. This allows for electrical connections to the diesel generator 40, energy storage module, and charging pile 50 via wiring channels and wiring holes running from the bottom of the enclosure 10. In this way, all power and communication cables are concealed at the bottom of the enclosure 10 through the bottom wiring channels and wiring holes, avoiding mechanical damage (such as being stepped on or collided with) and safety risks (such as electric shock or short circuits) caused by exposed cables.

[0035] See Figure 1 As shown, in some embodiments, the unfolding plate 110 occupies the entire wall of the long side of the enclosure. That is, after the unfolding plate 110 is unfolded, each chamber can be exposed from the side, forming a large-area operating platform, which facilitates equipment installation, commissioning and large-scale maintenance operations (such as replacing energy storage battery modules and overhauling diesel generator 40).

[0036] In a further embodiment, the photovoltaic module 20 is also disposed on the surface of the unfolding plate 110 to unfold or retract with the unfolding plate 110. Thus, after the unfolding plate 110 is unfolded, solar power generation can be further generated through the photovoltaic module 20 on the unfolding plate 110 to supplement the power of the energy storage cabinet 30, improve the overall energy utilization efficiency, and adapt to more outdoor environment needs.

[0037] The unfolding plate 110 can be driven by a high-precision servo motor with multi-stage hinges, achieving stepless adjustment from 0° to 180° with an angle control accuracy of ±0.5°. When adjusted to 0°, the unfolding plate 110 is in a retracted state, forming a closed environment around the housing 10 to protect the internal electrical components. When unfolded, the unfolding angle is preferably no less than 60 degrees, allowing for full solar energy reception and facilitating access for users or vehicles to the area beneath the unfolding plate 110. In a more preferred embodiment, the unfolding plate 110 dynamically adjusts its angle to track sunlight. This dynamic angle adjustment can integrate a solar tracking sensor, automatically calculating the optimal tilt angle based on parameters such as latitude, longitude, time, and cloud cover (e.g., tilt angle ≈ 0° in the equatorial region on the vernal equinox, and tilt angle ≈ 35° in the Beijing region on the winter solstice), but it must not be lower than the minimum tilt angle.

[0038] Understandably, the arrangement of the photovoltaic module 20 and the unfolding plate 110 allows for full absorption and utilization of solar energy after the unfolding plate 110 is unfolded. However, since the photovoltaic module 20 is located on the outer surface of the unfolding plate 110, when the unfolding plate 110 is closed, the photovoltaic module 20 is located on both sides of the housing 10. During the transfer and transportation of the housing 10, the photovoltaic modules 20 on both sides are easily damaged by collisions or friction. Therefore, in some other embodiments, the lower side of the unfolding plate 110 is hinged to the lower end of the housing 10, and the photovoltaic module 20 is set on the inner surface of the unfolding plate 110. In this case, although some solar energy may be sacrificed due to the shading of the housing, the photovoltaic module 20 can be stored inside the housing 10 when the unfolding plate 110 is closed, thus protecting the photovoltaic module 20.

[0039] See Figure 1 As shown, in some embodiments, the number of charging piles 50 is arranged in two rows along the length of their respective chambers, with each row of charging piles 50 facing an unfolding plate 110. This means that the unfolding plates 110 on both sides make efficient use of space and improve charging efficiency. For example, each row of charging piles 50 is spaced three apart, thus forming six charging positions on both sides of the housing 10, which can meet the simultaneous charging needs of multiple electric vehicles after the unfolding plates 110 are unfolded.

[0040] In some embodiments, the container 10 is designed as a shipping container. The standard container dimensions are directly adaptable to rail, road, and sea transport, reducing logistics costs by 30%–40%. The charging piles 50, photovoltaic modules 20, energy storage modules, etc., inside the container can all be pre-installed in the factory; only foundation pouring and pipeline connection are required on-site, greatly shortening the installation cycle.

[0041] Furthermore, the container 10 has lifting holes (not shown in the attached diagram) at its top and / or bottom four corners. These lifting holes are adapted to spreader attachments, allowing for top or bottom lifting, enabling vertical lifting, stacking, and horizontal transport of the container. In extreme weather conditions (such as typhoons or earthquakes), steel cables or anchor chains can be connected through the lifting holes to secure the container to the ground or building structure, preventing overturning.

[0042] The above description is only a part or preferred embodiment of this application. Neither the text nor the drawings should limit the scope of protection of this application. All equivalent structural transformations made using the content of this application's specification and drawings under the overall concept of this application, or direct / indirect applications in other related technical fields, are included within the scope of protection of this application.
