For ordinary technicians in this field, the specific meanings of the above terms in this embodiment can be understood according to specific circumstances.

[0037] Combine the following Figures 1 to 4 , describing an embodiment of the present invention.

[0038] According to an embodiment of the present invention, an uninterruptible power supply energy storage system is provided, including an assembly box 100, wherein the assembly box 100 is divided into an electrical compartment 110, a battery compartment, a distribution room 120 and a first cavity, wherein the electrical compartment 110 and the battery compartment are located on the same side of the assembly box 100 along a first direction, the distribution room 120 and the first cavity are located on the same side of the assembly box 100 along a first direction, the electrical compartment 110 and the distribution room 120 are arranged opposite to each other along the first direction, and the battery compartment and the first cavity are arranged opposite to each other along the first direction; the distribution room 120 is provided with a plurality of load interfaces; an energy storage battery 200 is arranged in the battery compartment, and a diesel fuel is arranged outside the assembly box 100. The diesel generator 300, the electrical compartment 110 is provided with a first energy storage inverter 111, a second energy storage inverter 112 and a transformer 113, the first energy storage inverter 111 is used to convert the alternating current output by the diesel generator 300 into direct current and transmit it to the energy storage battery 200 for charging; the second energy storage inverter 112 is used to convert the direct current output by the energy storage battery 200 into alternating current and transmit it to the distribution room 120; the transformer 113 is used to transform the alternating current output by the second energy storage inverter 112 and transmit it to the distribution room 120; the first cavity is provided with a charging pile 400 connected to the load interface of the distribution room 120.

[0039] The uninterruptible power supply energy storage system of this embodiment is achieved by arranging the electrical compartment 110 and the battery compartment on the same side of the assembly box 100 along the first direction, the distribution room 120 and the first cavity are located on the same side of the assembly box 100 along the first direction, and the electrical compartment 110 and the distribution room 120 are arranged relative to each other along the first direction, that is, the projection of the distribution room 120 along the first direction at least partially overlaps with the electrical compartment 110, the projection of the battery compartment along the second direction at least partially overlaps with the electrical compartment 110, and the projection of the charging pile 400 along the second direction at least partially overlaps with the distribution room 120, By making good use of the space of the assembly box 100 for design, the length of the required wires and the space required for arranging the wires are greatly reduced while ensuring the stable and efficient electrical connection between the energy storage battery 200, the first energy storage converter 111, the second energy storage converter 112, the transformer 113, the power distribution room 120 and the charging pile 400. The wire arrangement is more concise and convenient for maintenance, and the layout is compact and reasonably designed; the uninterruptible power supply energy storage system of this embodiment can be applied to an off-grid environment installed in a narrower space to provide uninterruptible power supply to the external load 700. In addition, by first storing the electric energy generated by the diesel generator 300 in the energy storage battery 200, and then using the storage battery to power the external load 700, it can effectively avoid the phenomenon that the external load 700 cannot be normally powered during the diesel generator 300 shutdown and refueling process, and meet the off-grid use scenario requiring uninterruptible power supply.

[0040] It should be noted that the off-grid usage scenario in this embodiment refers to off-grid high-power load scenarios such as construction sites, and the external load 700 refers to construction site crane equipment with a power of more than several hundred kilowatts. The traditional diesel generator 300 is used to directly supply power, and a diesel generator 300 with a power greater than the power of the construction site crane equipment is required, and the voltage level of the external load 700 is 400V, while the voltage level of the output end of the emergency power generation equipment that is traditionally powered directly by the diesel generator 300 is higher, and the user needs to purchase an additional transformer 113 for assembly and transformation to meet the adaptation requirements; in this embodiment, a transformer 113 is integrated in the electrical compartment 110, and the energy storage battery 200 is used to continuously discharge the external load 700. It only needs to configure a diesel generator 300 with a power less than the power of the construction site crane equipment to ensure that the system of this embodiment can continuously output a load to the external load 700 that meets the power of the construction site crane equipment, thereby eliminating the step and cost of the user to additionally match the transformer 113.

[0041] The uninterruptible power supply energy storage system of this embodiment arranges a charging pile 400 in the first cavity. The charging pile 400 is located on a side adjacent to the distribution room 120 along the second direction, so that a shorter wire can be used to pass through the overlapping part of the distribution room 120 and the projection of the first cavity along the second direction and a relatively simple wiring method to electrically connect the charging pile 400 with the load interface of the distribution room 120; and the charging pile 400 can also provide emergency charging services for electric vehicles 800 located in off-grid usage scenarios, alleviate "mileage anxiety", and promote the further popularization of electric vehicles 800.

[0042] It can be understood that the off-grid mentioned in the text refers to a scenario where the system is separated from the main power grid 600 and operates independently for power generation.

[0043] It can be understood that the first direction and the second direction mentioned in the text are located in the same horizontal plane, and the first direction, the second direction and the vertical direction are perpendicular to each other. For the convenience of description, this embodiment is based on Figures 2 to 4 The first direction, the second direction and the vertical direction shown in the figure are described as the first direction, the second direction and the vertical direction, respectively, but should not be understood as a clear limitation on the first direction, the second direction and the vertical direction.

[0044] Specifically, the load interface connecting the distribution room 120 and the charging pile 400 is set to a CEE PLUG quick-plug interface to electrically connect the charging pile 400 to the distribution room 120; the remaining load interfaces of the distribution room 120 can be set to a 32A single-phase interface, a 63A to 400A three-phase interface with various specifications, etc., so that multiple types of electrical equipment can be connected; each line also has an independent electric meter and a communication function, which can independently measure the power consumption of each load.

[0045] In some embodiments, a slide rail is provided at the inner bottom of the first cavity, the slide rail is provided along a first direction, and one end extends to the outer surface of the assembly box 100, and a pulley is provided at the bottom of the charging pile 400, the pulley is slidably provided on the slide rail and is locked by a locking assembly; by sliding the charging pile 400 in the first cavity, when the charging pile 400 needs to be inspected, the locking assembly can be unlocked and the charging pile 400 can be pulled out of the first cavity for operation and maintenance; when the inspection is completed, the charging pile 400 can be pushed back and hidden in the first cavity to reduce the occupied space.

[0046] Specifically, the locking assembly adopts a pedal locking piece of a common model currently available on the market. The structure of the locking assembly is not improved here and will not be elaborated here.

[0047] like Figure 1As shown, in some embodiments, the uninterruptible power supply energy storage system further includes a photovoltaic power generation device 500 disposed outside the assembly box 100, and the first energy storage converter 111 is also used to convert the AC power output by the photovoltaic power generation device 500 into DC power and transmit it to the energy storage battery 200 for charging. By adding the photovoltaic power generation device 500, the solar energy in the off-grid usage scenario can be effectively utilized, and the solar energy can be converted into electrical energy to charge the energy storage battery 200, so that the energy storage battery 200 can better continuously supply power to the external load 700.

[0048] Specifically, the photovoltaic power generation device 500 adopts a common photovoltaic power generation system currently available on the market. The structure of the photovoltaic power generation device 500 is not improved here, and thus will not be elaborated.

[0049] Specifically, the uninterruptible power supply energy storage system also includes a wind power generation device arranged outside the assembly box 100, and the first energy storage converter 111 is also used to convert the AC power output by the wind power generation device into DC power and transmit it to the energy storage battery 200 for charging. By adding wind power generation equipment, wind energy in off-grid usage scenarios can be effectively utilized, and the wind energy can be converted into electrical energy to charge the energy storage battery 200, so that the energy storage battery 200 can continuously supply power to the external load 700.

[0050] Specifically, the wind power generation equipment adopts a common type of wind power generation system currently available on the market. The structure of the wind power generation equipment is not improved here, so it will not be elaborated.

[0051] During specific use, photovoltaic power generation equipment 500 and wind power generation equipment are preferentially used to charge the energy storage battery 200. When the electric energy generated by the photovoltaic power generation equipment 500 and the wind power generation equipment is insufficient to compensate for the electric energy consumed by the energy storage battery 200 during discharge, and the electric power in the energy storage battery 200 is as low as 20% to 30% of the full charge state, the diesel generator 300 is used to charge the energy storage battery 200.

[0052] In specific applications, such as Figure 1 As shown, if this embodiment is applied in a grid-connected environment, that is, connected to the main grid 600, the output end of the main grid 600 can be connected to the output end of the first energy storage inverter 111, so that the AC power output by the main grid 600 is converted into DC power and transmitted to the energy storage battery 200 for charging; and when the power generation of the photovoltaic power generation equipment 500 and the wind power generation equipment is sufficient and there is still power left after the energy storage battery 200 is fully charged, the remaining power can be transmitted to the main grid 600 to realize grid-connected power generation.

[0053] In some embodiments, an exhaust fan is provided on the inner wall of the electrical compartment 110, and a first temperature probe is provided in the electrical compartment 110. The first temperature probe is used to detect the temperature inside the electrical compartment 110 to obtain a first temperature value, and transmit the first temperature value to a controller. The controller compares the first temperature value with a first standard temperature value, and outputs a first adjustment instruction when the first temperature value is greater than the first standard temperature value, and controls the exhaust fan to start according to the first adjustment instruction. The first energy storage converter 111, the second energy storage converter 112, and the transformer 113, which are components with high heat generation, are integrated in the electrical compartment 110. In order to dissipate heat, the traditional heat dissipation method is to keep the heat dissipation fan on during the entire power supply process, resulting in high auxiliary power consumption. In this embodiment, a first temperature probe is provided inside the electrical compartment 110 to detect the internal temperature of the electrical compartment 110 in real time and obtain the first temperature value. After receiving the first temperature value, the controller compares the first temperature value with the first standard temperature value, and when the internal temperature of the electrical compartment 110 is higher than the first standard temperature value, the exhaust fan is controlled to start strong exhaust, and there is no need to keep the exhaust fan on, which is conducive to reducing auxiliary power consumption.

[0054] Specifically, the controller is also used to compare the first temperature value with the third standard temperature value, output a third adjustment instruction when the first temperature value is less than the third standard temperature value, and control the exhaust fan to stop according to the third adjustment instruction; when the exhaust fan is started to exhaust air for a period of time so that the internal temperature of the electrical compartment 110 drops below the third standard temperature value, the exhaust fan is controlled to stop, so that the exhaust fan stops after the internal heat of the electrical compartment 110 is effectively dissipated after starting the exhaust fan. Compared with keeping the exhaust fan on after starting, this embodiment is more conducive to reducing auxiliary power consumption.

[0055] Taking into account the large temperature difference between day and night in some off-grid usage scenarios, the temperature can drop to single digits at night. In order to utilize this part of the cooling capacity, specifically, the inner wall of the electrical compartment 110 is provided with an air inlet fan, and the outside of the assembly box 100 is provided with a second temperature probe, the second temperature probe is used to detect the temperature outside the assembly box 100 to obtain a second temperature value, and transmit the second temperature value to the controller, the controller compares the second temperature value with a second standard temperature value, outputs a second adjustment instruction when the second temperature value is less than the second standard temperature value, and controls the start of the air inlet fan according to the second adjustment instruction. The external environment temperature is detected in real time by the second temperature probe and a second temperature value is obtained. After receiving the second temperature value, the controller compares the second temperature value with the second standard temperature value, and when the external environment temperature is lower than the second standard temperature value, the exhaust fan is controlled to start a low-power air intake, so that the low-temperature cold air in the external environment is gathered in the electrical compartment 110 for cold storage. On the one hand, it is beneficial to keep the first energy storage inverter 111, the second energy storage inverter 112 and the transformer 113 and other components with higher heat generation in the electrical compartment 110 under a suitable storage temperature environment to extend the life of the components. On the other hand, the cold air gathers in the electrical compartment 110, which reduces the heating rate of the first energy storage inverter 111, the second energy storage inverter 112 and the transformer 113 and other components with higher heat generation after the external environment temperature rises, thereby reducing the opening time of the exhaust fan. Compared with the traditional heat dissipation method, the efficiency of this embodiment can be improved by at least 1%.

[0056] It should be noted that the first standard temperature value refers to the limit temperature value before the temperature in the electrical compartment 110 rises to affect the working performance of the first energy storage converter 111, the second energy storage converter 112, the transformer 113 and other components with higher heat generation; the second standard temperature value refers to the single-digit temperature value that does not affect the use performance of the first energy storage converter 111, the second energy storage converter 112, the transformer 113 and other components with higher heat generation, and is conducive to prolonging the first energy storage converter 111, the second energy storage converter 112, the transformer 113 and other components with higher heat generation; the third standard temperature value refers to the temperature in the electrical compartment 110 drops to the normal temperature that does not affect the working performance of the first energy storage converter 111, the second energy storage converter 112, the transformer 113 and other components with higher heat generation. Specifically, in this embodiment, the first standard temperature value is selected as 50°C, the second standard temperature value is selected as 5°C, and the third standard temperature value is selected as 40°C.

[0057] In some embodiments, the uninterruptible power supply energy storage system further includes a movable component, and the assembly box 100 has a first state of being plugged in with the movable component, and a second state of being separated from the movable component. When the uninterruptible power supply energy storage system of this embodiment needs to be transferred, the assembly box 100 is switched to the first state by a crane to be assembled with the movable component, so as to facilitate the transfer and use between different off-grid usage scenarios; after being transferred to the corresponding off-grid usage scenario, the assembly box 100 is switched to the second state by a crane, so as to assemble the assembly box 100 in a relatively narrow space of the off-grid usage scenario to provide uninterruptible power supply to the external load 700.

[0058] Specifically, one of the assembly box 100 and the movable component is provided with a first positioning plug-in component, and the other is provided with a second positioning plug-in component. When the assembly box 100 is in the first state, the first positioning plug-in component is plugged with the second positioning plug-in component. In the process of switching the assembly box 100 to the first state, the first positioning plug-in component and the second positioning plug-in component are guided and positioned to plug each other, ensuring that the assembly box 100 is accurately switched to the first state, thereby ensuring that the assembly box 100 and the movable component are accurately combined into a whole, so as to transfer the uninterruptible power supply energy storage system of this embodiment.

[0059] The structures of the first positioning plug-in assembly and the second positioning plug-in assembly of this embodiment are described below.

[0060] In some embodiments, the first positioning plug-in component includes a plurality of positioning pins, preferably four positioning pins, which are arranged at intervals along a rectangular outline, and the four positioning pins are arranged on the upper end surface of the movable component; the second positioning plug-in component includes a positioning hole arranged on the lower end surface of the assembly box 100 at a position corresponding to the positioning pin, and the positioning hole matches the positioning pin. In the process of switching the assembly box 100 to the first state, the positioning pin is aligned with the corresponding positioning hole, and then the positioning hole is inserted down to engage with the positioning pin, ensuring that the assembly box 100 is accurately switched to the first state.

[0061] Specifically, the outer wall of the lower end of the assembly box 100 is provided with a connection ear, and the positioning hole is formed through the connection ear in the vertical direction; the positioning pin is provided as a screw portion, and when the assembly box 100 is in the first state, the screw portion passes through the positioning hole and is threadedly connected with a nut. After the assembly box 100 is switched to the first state, a nut is further threadedly connected to the portion of the screw portion extending outside the positioning hole to further lock it, thereby improving the locking effect of the assembly box 100 in the first state and the mobile component, and in the process of transferring the uninterruptible power supply energy storage system of this embodiment, it is helpful to reduce the risk of separation between the mobile component and the assembly box 100.

[0062] In a specific application, the mobile component is selected as a tractor or a flatbed truck to transfer the uninterruptible power supply energy storage system of this embodiment.

[0063] Although the embodiments of the present invention have been described in conjunction with the accompanying drawings, those skilled in the art may make various modifications and variations without departing from the spirit and scope of the present invention, and such modifications and variations are all within the scope defined by the appended invention.
