In the present application, an accommodating cavity of a cabinet body of a main charging unit in the charging device can be divided into a first accommodating cavity and a second accommodating cavity in a first direction, a plurality of power conversion modules of the main charging unit are stacked in the first accommodating cavity in a second direction, and a plurality of power distribution modules of the main charging unit are stacked in the second accommodating cavity in the second direction.

Technical Field

[0002] The present application relates to the field of energy technology, and in particular to a charging device. Background Art

[0003] With the rapid development of the new energy vehicle industry, the charging power of electric vehicles has gradually increased, and charging needs have become increasingly diverse. To meet the charging needs of different vehicles while improving power utilization, modular charging hosts have received attention and development.

[0004] Currently, modular charging consoles often utilize a vertically stacked module architecture with an air-to-liquid heat exchanger placed on top. Specifically, the modules within the charging console are stacked vertically, with the air-to-liquid heat exchanger placed on top. However, the more modules stacked vertically in this architecture, the taller the modular charging console becomes, making it difficult to place the modular charging console in locations with height restrictions.

[0005] [Corrected 20.02.2025 in accordance with Rule 91] Summary of the invention

[0006] In a first aspect, the present application provides a charging device comprising a charging main unit, the charging main unit comprising a cabinet, a plurality of power conversion modules, and a plurality of power distribution modules. The cabinet comprises a first receiving chamber and a second receiving chamber, the first receiving chamber and the second receiving chamber being sequentially arranged and spaced apart along a first direction; the plurality of power conversion modules are configured to convert input alternating current (AC) into direct current (DC); the plurality of power distribution modules are configured to distribute the DC output by the plurality of power conversion modules; the plurality of power conversion modules are stacked within the first receiving chamber along a second direction, the first direction being different from the second direction; and the plurality of power distribution modules are stacked within the second receiving chamber along the second direction.

[0007] It can be seen that in this embodiment, the receiving cavity of the cabinet of the charging host can be divided into a first receiving cavity and a second receiving cavity along the first direction, and multiple power conversion modules of the charging host are arranged in the first receiving cavity to be stacked along the second direction, and multiple power distribution modules of the charging host are arranged in the second receiving cavity to be stacked along the second direction. Since the first receiving cavity is different from the second receiving cavity, multiple power conversion modules and multiple power distribution modules can be stacked in different spaces. At the same time, multiple power conversion modules and multiple power distribution modules are stacked along the same direction, and the stacking direction is different from the direction in which the receiving cavities are arranged. Therefore, this embodiment can avoid as much as possible the deficiencies caused by the stacking direction being the same as the direction in which the receiving cavities are arranged. For example, when the stacking direction is the same as the direction in which the receiving cavities are arranged, and both are longitudinal or vertical directions, this will cause the overall height of the charging host to be too high.

[0008] Optionally, the first direction is a longitudinal or vertical direction, and the second direction is a transverse or horizontal direction. Thus, this embodiment can change the stacking orientation of the multiple power conversion modules and the multiple power distribution modules in the charging host from a longitudinal stacking orientation to a transverse stacking orientation. In other words, the multiple power conversion modules and the multiple power distribution modules, which were originally stacked vertically, are now stacked horizontally. By changing the stacking orientation of the multiple power conversion modules and the multiple power distribution modules, the height of the charging host can be minimized.

[0009] Optionally, the first direction is the Z direction or the Y direction in the three-dimensional coordinate system, and the second direction is the X direction in the three-dimensional coordinate system. In this way, by setting the stacking direction of the multiple power conversion modules and the multiple power distribution modules to the X direction, the height of the charging host can be minimized.

[0010] Optionally, multiple power conversion modules are stacked in a single row or multiple rows along the second direction in the first receiving cavity; multiple power distribution modules are stacked in a single row or multiple rows along the second direction in the second receiving cavity.

[0011] In this way, the present application flexibly arranges whether to stack multiple power conversion modules or multiple power distribution modules in a single row or multiple rows according to needs within the cabinet's receiving cavity. Among them, when multiple power conversion modules or multiple power distribution modules are stacked in a single row, this embodiment can achieve simple and rapid stacking of multiple power conversion modules or multiple power distribution modules. When multiple power conversion modules or multiple power distribution modules are stacked in multiple rows, this embodiment can place more power conversion modules or power distribution modules in a limited cabinet, thereby improving space utilization.

[0012] Optionally, multiple power conversion modules include multiple AC rectifier modules and multiple DC voltage regulation modules; multiple AC rectifier modules are used to convert AC power input into the charging host into DC power; multiple DC voltage regulation modules are used to adjust the voltage of the DC power output by the multiple AC rectifier modules; multiple AC rectifier modules and multiple DC voltage regulation modules are stacked along the second direction in the first receiving cavity.

[0013] In this way, the AC power is converted into DC power and the voltage of the DC power is adjusted through the AC rectifier module and the DC voltage regulator module.

[0014] Optionally, some of the multiple DC voltage regulation modules are located on one side of the multiple AC rectifier modules, and the remaining DC voltage regulation modules are located on the other side of the multiple AC rectifier modules.

[0015] In this way, when the number of DC voltage regulator modules needs to be reduced, this embodiment can quickly and conveniently remove the DC voltage regulator module located on one side of multiple AC rectifier modules, avoiding a large number of adjustments to the entire stacked power conversion module, reducing the adjustment workload and time.

[0016] Optionally, the multiple DC voltage regulation modules are integrally located on one side of the multiple AC rectifier modules.

[0017] In this way, since all DC voltage regulation modules are stacked together and all AC rectifier modules are stacked together, this embodiment can quickly and conveniently remove a certain number of DC voltage regulation modules from all DC voltage regulation modules or remove a certain number of AC rectifier modules from all AC rectifier modules without affecting the stacking between other modules.

[0018] Optionally, multiple AC rectifier modules are connected via an AC busbar, which is used to transmit AC power.

[0019] In this way, AC power can be input to multiple AC rectifier modules and AC power can be transmitted between multiple AC rectifier modules through the AC busbar.

[0020] Optionally, the AC busbar has a photovoltaic stacking function. Wherein, the AC busbar has a photovoltaic stacking function. It can be understood that the AC busbar can transmit the AC power output by the photovoltaic power generation system.

[0021] As can be seen, the charging device of this embodiment can be connected to a photovoltaic power generation system and convert the AC power output by the photovoltaic power generation system into DC power through the AC rectifier module. In this way, the charging device of this embodiment can use the AC power of the photovoltaic power generation system to charge electric vehicles.

[0022] Optionally, the multiple AC rectifier modules and the multiple DC voltage regulator modules are connected via a DC busbar, which is used to transmit DC power.

[0023] In this way, the DC power output by the multiple AC rectifier modules can be transmitted to the multiple DC voltage regulation modules through the DC busbar, and the DC power can be transmitted between the multiple DC voltage regulation modules.

[0024] Optionally, the DC busbar has a stacking storage function. The DC busbar having the stacking storage function means that the DC busbar can transmit the DC power output by the energy storage device. The energy storage device is a device that can store DC power.

[0025] As can be seen, the charging device of this embodiment can be connected to the energy storage device and regulate the voltage of the DC power output by the energy storage device through the DC voltage regulator module. In this way, the charging device of this embodiment can use the DC power of the energy storage device to charge the electric vehicle.

[0026] Optionally, a part of the multiple AC rectifier modules and a part of the DC voltage regulation modules in the multiple DC voltage regulation modules are connected through a first DC busbar, and the remaining AC rectifier modules in the multiple AC rectifier modules and the remaining DC voltage regulation modules in the multiple DC voltage regulation modules are connected through a second DC busbar. The first DC busbar and the second DC busbar are used to transmit DC power, and the first DC busbar is different from the second DC busbar.

[0027] As can be seen, this embodiment can connect some AC rectifier modules and some DC voltage regulator modules via the first DC busbar, and connect the remaining AC rectifier modules and the remaining DC voltage regulator modules via the second DC busbar. In this way, when it is necessary to reduce the number of AC rectifier modules and DC voltage regulator modules, this embodiment can conveniently and quickly adjust the circuit of one of the DC busbars without adjusting the circuit of the other DC busbar, thereby reducing the amount of DC busbar circuit adjustment.

[0028] Optionally, the first DC busbar and / or the second DC busbar has a stacking storage function.

[0029] As can be seen, the charging device of this embodiment can be connected to the energy storage device and regulate the voltage of the DC power output by the energy storage device through the DC voltage regulator module. In this way, the charging device of this embodiment can use the DC power of the energy storage device to charge the electric vehicle.

[0030] Optionally, multiple DC voltage regulation modules are directly plugged into multiple power distribution modules.

[0031] In this way, by directly plugging in, the transmission loss of DC power between multiple DC voltage regulation modules and multiple power distribution modules can be reduced, while the line layout between multiple DC voltage regulation modules and multiple power distribution modules can be reduced, reducing line materials and improving space utilization.

[0032] Optionally, the ratio of the number of AC rectifier modules in the multiple AC rectifier modules to the number of DC voltage regulation modules in the multiple DC voltage regulation modules is inversely proportional to the ratio of the power of the multiple AC rectifier modules to the power of the multiple DC voltage regulation modules.

[0033] As can be seen, since the AC rectifier module is used to convert the AC power input to the charging host into DC power, and the DC voltage regulator module is used to adjust the voltage of the DC power output by the AC rectifier module, this embodiment needs to ensure that the ratio of the number of AC rectifier modules to the number of DC voltage regulator modules is inversely proportional to the ratio of the power of the multiple AC rectifier modules to the power of the multiple DC voltage regulator modules. In this way, the number of AC rectifier modules multiplied by the power of the AC rectifier modules can be equal to the number of DC voltage regulator modules multiplied by the power of the DC voltage regulator modules.

[0034] Optionally, the charging host further includes an AC input module, which is used to receive AC power and input the AC power into multiple power conversion modules; the AC input module and the multiple power distribution modules are stacked along the second direction in the second receiving cavity.

[0035] In this way, the AC input module can realize the input of AC power from the outside to the charging host and the transmission of the AC power to the power conversion module for processing.

[0036] Optionally, a portion of the multiple power distribution modules are located on one side of the AC input module, and the remaining power distribution modules are located on the other side of the AC input module.

[0037] In this way, when the number of power distribution modules needs to be reduced, this embodiment can quickly and conveniently remove the power distribution module located on one side of the AC input module, avoiding a large number of adjustments to the entire stacked power distribution modules, reducing the adjustment workload and time.

[0038] Optionally, the multiple power distribution modules are integrally located on one side of the AC input module.

[0039] In this way, since all the power distribution modules are stacked together, this embodiment can quickly and conveniently remove a certain number of power distribution modules from all the power distribution modules without affecting the stacking of other modules.

[0040] Optionally, the charging host also includes a liquid cooling heat dissipation module, which is used to exchange heat with the external environment and transport the cooled coolant to the module of the charging host through a liquid cooling pipeline; the cabinet also includes a third receiving chamber, which is arranged in sequence and spaced apart from the first receiving chamber and the second receiving chamber along the first direction or the second direction; the liquid cooling heat dissipation module is in the third receiving chamber.

[0041] In this way, the modules of the charging host (such as the power conversion module, the power distribution module, etc.) can be cooled by the liquid cooling heat dissipation module.

[0042] Optionally, the third receiving cavity is provided on one side or both sides of the first receiving cavity and the second receiving cavity.

[0043] In this way, the present application can flexibly set the position of the liquid cooling module in the cabinet.

[0044] Optionally, the cabinet includes multiple cabinet doors, and the multiple cabinet doors are arranged relatively along the first direction or the second direction.

[0045] In this way, the interior space of the cabinet can be opened through the multiple cabinet doors, so that the modules in the cabinet can be easily set.

[0046] Optionally, the charging device also includes at least one charging terminal, which is used to output the direct current distributed by multiple power distribution modules; the charging host also includes a charging connection module, which is used to connect the charging host to at least one charging terminal; the cabinet also includes a fourth receiving cavity, which is arranged in sequence with the first receiving cavity and the second receiving cavity along the second direction and is spaced apart; the charging connection module is in the fourth receiving cavity.

[0047] In this way, the charging host can be connected to at least one charging terminal through the charging connection module, so as to form an integrated charging device integrating the charging host and the charging terminal.

[0048] Optionally, at least one charging terminal includes at least one charging gun; the at least one charging gun is arranged on a first outer side of the cabinet, and the first outer side faces the second direction.

[0075] In order to better understand the technical solution of this application, the technical solution of this application is clearly and completely described below in conjunction with the drawings in this application. Obviously, the embodiments described are only some embodiments of this application, not all embodiments. Based on the description of the embodiments of this application, all other embodiments obtained by those skilled in the art without making any creative work are within the scope of protection of this application.

[0076] It should be understood that the terms "first," "second," and the like used in this application are used to distinguish between different objects, rather than to describe a specific order. Furthermore, the terms "including," "having," and any variations thereof, are intended to cover non-exclusive inclusions. For example, a process, method, software, product, or apparatus comprising a series of steps or elements is not limited to the listed steps or elements, but may also include steps or elements not listed, or other steps or elements inherent to the process, method, product, or apparatus.

[0077] The phrase "embodiment" used in this application means that a particular feature, structure, or characteristic described in connection with the embodiment may be included in at least one embodiment of this application. The appearance of this phrase in various places in the specification does not necessarily refer to the same embodiment, nor does it constitute an independent or alternative embodiment that is mutually exclusive of other embodiments. Furthermore, the embodiments described herein may be combined with other embodiments.

[0078] In the embodiments of this application, "and / or" can describe the relationship between associated objects, and three types of relationships can exist. For example, A and / or B can represent the following three situations: "A", "B", and "A and B". A and B can be singular or plural.

[0079] In the embodiments of the present application, the symbol " / " can indicate that the preceding and following objects are in an "or" relationship. In addition, the symbol " / " can also represent a division sign, that is, performing a division operation. For example, A / B can mean A divided by B.

[0080] In the embodiments of the present application, "at least one item" or similar expressions refers to any combination of these items, including any combination of single items or plural items, and refers to one or more, and "multiple" refers to two or more. For example, at least one item among a, b or c can represent the following seven situations: "a", "b", "c", "a and b", "a and c", "b and c", "a, b and c". Among them, each of a, b, and c can be an element or a set containing one or more elements.

[0081] In the embodiments of the present application, "coupling" and "connection" can be used to indicate electrical connection, which can include direct connection through wires or connectors or indirect connection through other devices (such as inductors, capacitors, or resistors). Therefore, "coupling" and "connection" can be regarded as a broad sense of electronic communication connection. In addition, the mutual coupling / direct coupling / connection shown or discussed can be indirect coupling or connection through some interface, device, unit or device, which can be in the form of communication, electrical or other forms.

[0082] Various circuits or other components in the embodiments of the present application may be described as being "configured to" perform one or more tasks. In this case, "configured to" may imply a structure by indicating that the circuit / component includes a structure (e.g., circuitry) that performs the one or more tasks during operation. Thus, even when a specified circuit / component is not currently operational, the circuit / component may be said to be configured to perform the task. Circuits / components used with the term "configured to" include hardware, such as circuits that perform an operation, etc.

[0083] A charging device is a device that converts AC power into DC power and provides charging needs for electric vehicles.

[0084] Optionally, the charging device may include a charging host and a charging terminal. In other words, the charging device may be an integrated charging device that integrates the charging host and the charging terminal.

[0085] A charging host is a device that converts AC power into DC power, regulates the DC voltage, and then distributes the regulated DC power. This device typically includes components such as a rectifier, filter, transformer, and inverter.

[0086] A charging terminal is a device that receives DC power from a charging host and connects to and charges an electric vehicle. It typically includes a socket, connecting cables, and related control circuitry. Users plug the electric vehicle's charging plug into the charging terminal's socket and connect the charging terminal to the electric vehicle via the connecting cable.

[0087] The following is an example of the charging scenario provided by the charging device. Figure 1 is a schematic diagram of a charging scenario of this embodiment. In Figure 1, the charging device 110 can be used in a scenario of charging an electric vehicle 120. The input end of the charging device 110 can be connected to the power grid 130, and the output end of the charging device 110 can be connected to the electric vehicle 120. Among them, the charging device 110 can convert the alternating current in the power grid 130 into direct current, and distribute the direct current to the electric vehicle 120 after regulating the voltage, thereby charging the electric vehicle 120. The electric energy in the power grid 130 can be industrial electricity, or civilian electricity, etc.

[0088] The functions of the charging device can be modularized. That is, the charging device can be divided into different functional modules according to its different functions, and the interface between different functional modules can be fixed or evolve with the corresponding power. In this way, this embodiment can combine different functional modules to achieve different functions, and the charging device's capabilities can be adjusted by increasing or decreasing the number of functional modules.

[0089] For example, to modularize the power conversion function of the charging device, this embodiment can introduce a power conversion module. The power conversion module can be used to convert alternating current (AC) into direct current (DC) and regulate the voltage of the DC. The power conversion module can be referred to as a power module. Furthermore, there can be multiple power conversion modules, and the number of power conversion modules can be adjusted as needed to adjust the power conversion capacity of the charging device by increasing or decreasing the number of power conversion modules. Generally, the more power conversion modules there are, the greater the power conversion capacity of the charging device.

[0090] For another example, to modularize the power distribution function of the charging device, this embodiment can introduce a power distribution module. The power distribution module can be used to distribute the DC power regulated by the power conversion module to the charging terminal. The power distribution module can be called a power matrix. Furthermore, there can be multiple power distribution modules, and the number of power distribution modules can be adjusted as needed to adjust the power distribution capacity of the charging device by increasing or decreasing the number of power distribution modules. Generally, the more power distribution modules there are, the greater the power distribution capacity of the charging device.

[0091] The modularization of the charging device is illustrated below. Figure 2 is a schematic diagram of the functional modules of a charging device according to this embodiment. In Figure 2, the charging device 20 includes a charging host 210 and a charging terminal 220. The charging host 210 includes multiple power conversion modules (such as power conversion module 2111, power conversion module 2112, power conversion module 2113, and power conversion module 2114) and multiple power distribution modules (such as power distribution module 2121, power distribution module 2122, and power distribution module 2123).

[0092] Currently, modular charging consoles often utilize a vertically stacked module architecture with an air-to-liquid heat exchanger placed on top. Specifically, the modules are stacked vertically, with the air-to-liquid heat exchanger placed on top. However, the more modules are stacked vertically in this architecture, the taller the modular charging console becomes, making it difficult to place the modular charging console in locations with height restrictions.

[0093] For example, taking the vertical direction as the Z direction in a three-dimensional coordinate system, FIG3 is a schematic diagram of a modular charging host architecture using vertically stacked modules in this embodiment. In FIG3 , the charging host 30 includes a cabinet 310, multiple power conversion modules 320 (such as power conversion module 3201, power conversion module 3202, power conversion module 3203, power conversion module 3204, power conversion module 3205, and power conversion module 3206), and an air-to-liquid heat exchanger 330. The multiple power conversion modules are stacked sequentially from bottom to top along the Z direction, and the air-to-liquid heat exchanger 330 is placed on top of the cabinet 310. Thus, for high-power scenarios, this architecture requires more power conversion modules. The more power conversion modules, the higher the overall height of the charging host 30, making it impossible to place the charging host 30 in places with height restrictions.

[0094] Since the modular charging host adopts the structure of vertically stacking modules and the top-mounted air-to-liquid heat exchanger cannot be used in places with height restrictions, this embodiment needs to optimize the direction of module stacking to avoid the height of the modular charging host being too high as much as possible.

[0095] In the following embodiment, the "modular charging host" is referred to as the "charging host", and the following multiple solutions are used to illustrate how to optimize the direction of module stacking. The same content between different solutions can be referenced by each other, and will not be repeated here.

[0096] [Scheme 1]

[0097] In "Solution 1," this embodiment changes the stacking orientation of the multiple power conversion modules and power distribution modules in the charging host from vertical to horizontal. In other words, the multiple power conversion modules and power distribution modules, previously stacked vertically, are now stacked horizontally. This change in stacking orientation minimizes the height of the modular charging host.

[0098] In the following, this embodiment is specifically described by taking the longitudinal direction as the Z direction in the three-dimensional coordinate system and the transverse direction as the X direction in the three-dimensional coordinate system as an example.

[0099] In "Scheme 1," this embodiment can divide the charging host cabinet's receiving cavity into two upper and lower receiving cavities (referred to as the "first receiving cavity" and the "second receiving cavity" for ease of description) along the Z direction (for ease of description, the "Z direction" here can be referred to as the "first direction"), and then place multiple power conversion modules in the first receiving cavity, and multiple power distribution modules in the second receiving cavity. The multiple power conversion modules are stacked along the X direction in the first receiving cavity, and the multiple power distribution modules are stacked along the X direction in the second receiving cavity (for ease of description, the "X direction" here can be referred to as the "second direction").

[0100] For example, Figure 4 is a schematic diagram of the structure of a charging host according to this embodiment. In Figure 4, the charging host 40 includes a cabinet 410, multiple power conversion modules 420 (such as power conversion module 4201, power conversion module 4202, power conversion module 4203, power conversion module 4204, power conversion module 4205, and power conversion module 4206), and multiple power distribution modules 430 (such as power distribution module 4301, power distribution module 4302, power distribution module 4303, power distribution module 4304, power distribution module 4305, and power distribution module 4306). The receiving cavity of the cabinet 410 is divided into a first receiving cavity 4101 and a second receiving cavity 4102 along the Z direction. Multiple power conversion modules 420 are stacked along the X direction in the first receiving cavity 4101, and multiple power distribution modules 430 are stacked along the X direction in the second receiving cavity 4102.

[0101] Optionally, multiple power conversion modules are stacked in a single row or multiple rows in the first receiving cavity; multiple power distribution modules are stacked in a single row or multiple rows in the second receiving cavity.

[0102] In this way, this embodiment allows for flexible arrangement of the cabinet's receiving cavity, whether to stack multiple power conversion modules or multiple power distribution modules in a single row or multiple rows, as required. When stacking multiple power conversion modules or multiple power distribution modules in a single row, this embodiment allows for simple and rapid stacking of the multiple power conversion modules or multiple power distribution modules. When stacking multiple power conversion modules or multiple power distribution modules in multiple rows, this embodiment allows for the placement of more power conversion modules or power distribution modules within the limited cabinet, thereby improving space utilization.

[0103] For example, in FIG4 , multiple power conversion modules 420 are stacked in a single row along the X direction in the first receiving cavity 4101 , and multiple power distribution modules 430 are stacked in a single row along the X direction in the second receiving cavity 4102 .

[0104] For another example, Figure 5 is a schematic diagram of the structure of a charging host according to this embodiment, viewed from above along the Z axis. In Figure 5, the charging host 50 includes a cabinet 510 and multiple power conversion modules 520 (e.g., power conversion module 5201, power conversion module 5202, power conversion module 5203, power conversion module 5204, power conversion module 5205, and power conversion module 5206). The multiple power conversion modules 520 are stacked in a single row along the X axis within the first receiving cavity 4101 of the cabinet 510.

[0105] For example, Figure 6 is a schematic diagram of the structure of another charging host according to this embodiment, viewed from above along the Z axis. In Figure 6, the charging host 60 includes a cabinet 610 and multiple power conversion modules 620 (such as power conversion module 6201, power conversion module 6202, power conversion module 6203, power conversion module 6204, power conversion module 6205, power conversion module 6206, power conversion module 6207, power conversion module 6208, power conversion module 6209, power conversion module 6210, power conversion module 6211, and power conversion module 6212). The multiple power conversion modules 620 are stacked in two rows along the X direction within the first receiving cavity 6101 of the cabinet 610. Among them, power conversion module 6201, power conversion module 6202, power conversion module 6203, power conversion module 6204, power conversion module 6205 and power conversion module 6206 are stacked in a row, and power conversion module 6207, power conversion module 6208, power conversion module 6209, power conversion module 6210, power conversion module 6211 and power conversion module 6212 are stacked in a row.

[0106] [Scheme 2]

[0107] In "Solution 2," this embodiment changes the stacking orientation of the multiple power conversion modules and power distribution modules in the charging host from vertical to horizontal. In other words, the power conversion modules and power distribution modules, previously stacked vertically, are now stacked horizontally. This change in stacking orientation minimizes the height of the modular charging host.

[0108] In the following, this embodiment is specifically described by taking the longitudinal direction as the Z direction in the three-dimensional coordinate system and the transverse direction as the X direction in the three-dimensional coordinate system as an example.

[0109] In "Scheme 2," this embodiment can divide the charging host cabinet's receiving cavity along the Y direction (for ease of description, the "Y direction" here can be referred to as the "first direction") into two front and rear receiving cavities (for ease of description, the two receiving cavities are referred to as the "first receiving cavity" and the "second receiving cavity"). Multiple power conversion modules are then placed in the first receiving cavity, and multiple power distribution modules are placed in the second receiving cavity. The multiple power conversion modules are stacked along the X direction in the first receiving cavity, and the multiple power distribution modules are stacked along the X direction in the second receiving cavity (for ease of description, the "X direction" here can be referred to as the "second direction").

[0110] For example, FIG7 is a schematic diagram of the structure of another charging host according to this embodiment. In FIG7, the charging host 70 includes a cabinet 710, multiple power conversion modules 720 (such as power conversion module 7201, power conversion module 7202, power conversion module 7203, power conversion module 7204, power conversion module 7205, and power conversion module 7206), and multiple power distribution modules 730 (such as power distribution module 7301, power distribution module 7302, power distribution module 7303, power distribution module 7304, power distribution module 7305, and power distribution module 7306). The receiving cavity of the cabinet 710 is divided into a front and rear first receiving cavity 7101 and a second receiving cavity 7102 along the Y direction. Multiple power conversion modules 720 are stacked along the X direction in the first receiving cavity 7101, and multiple power distribution modules 730 are stacked along the X direction in the second receiving cavity 7102.

[0111] Optionally, multiple power conversion modules are stacked in a single row or multiple rows in the first receiving cavity; multiple power distribution modules are stacked in a single row or multiple rows in the second receiving cavity.

[0112] In this way, this embodiment allows for flexible arrangement of the cabinet's receiving cavity, whether to stack multiple power conversion modules or multiple power distribution modules in a single row or multiple rows, as required. When stacking multiple power conversion modules or multiple power distribution modules in a single row, this embodiment allows for simple and rapid stacking of the multiple power conversion modules or multiple power distribution modules. When stacking multiple power conversion modules or multiple power distribution modules in multiple rows, this embodiment allows for the placement of more power conversion modules or power distribution modules within the limited cabinet, thereby improving space utilization.

[0113] [Scheme 3]

[0114] "Scheme 3" further explains the multiple power conversion modules and multiple power distribution modules mentioned in the above "Scheme 1" or "Scheme 2".

[0115] In "Scheme 3", the multiple power conversion modules include multiple AC rectifier modules and multiple DC voltage regulation modules; the multiple AC rectifier modules and the multiple DC voltage regulation modules are stacked along the X direction in the first receiving cavity.

[0116] A plurality of AC rectifier modules can be used to convert the AC power inputted into the charging host into DC power. The AC rectifier modules can include alternating current / direct current (AC / DC) converters.

[0117] The plurality of DC voltage regulating modules can be used to adjust the voltage of the DC power output by the plurality of AC rectifier modules, wherein the DC voltage regulating module can include a direct current / direct current (DC / DC) converter.

[0118] In this way, the AC power is converted into DC power and the voltage of the DC power is adjusted through the AC rectifier module and the DC voltage regulator module.

[0119] Optionally, some of the multiple DC voltage regulation modules are located on one side of the multiple AC rectifier modules, and the remaining DC voltage regulation modules are located on the other side of the multiple AC rectifier modules.

[0120] For example, Figure 8 is a schematic diagram of the front structure of a charging host according to this embodiment along the Y-axis. In Figure 8, the charging host 80 includes a cabinet 810, multiple AC rectifier modules 820 (such as AC rectifier module 8201, AC rectifier module 8202, AC rectifier module 8203, AC rectifier module 8204, AC rectifier module 8205, and AC rectifier module 8206), and multiple DC voltage regulator modules 830 (such as DC voltage regulator module 8301, DC voltage regulator module 8302, DC voltage regulator module 8303, DC voltage regulator module 8304, DC voltage regulator module 8305, DC voltage regulator module 8306, DC voltage regulator module 8307, DC voltage regulator module 8308, DC voltage regulator module 8309, DC voltage regulator module 8310, DC voltage regulator module 8311, and DC voltage regulator module 8312). The receiving cavity of the cabinet 810 is divided into a first receiving cavity 8101 and a second receiving cavity 8102 along the Z-direction. Multiple AC rectifier modules 820 and multiple DC voltage regulator modules 830 are stacked along the X direction within the first receiving cavity 8101. Part of the multiple DC voltage regulator modules 830 are located on one side of the multiple AC rectifier modules 820, and the remaining DC voltage regulator modules 830 are located on the other side of the multiple AC rectifier modules 820.

[0121] In this way, when the number of DC voltage regulator modules needs to be reduced, this embodiment can quickly and conveniently remove the DC voltage regulator module located on one side of multiple AC rectifier modules, avoiding a large number of adjustments to the entire stacked power conversion module, reducing the adjustment workload and time.

[0122] Optionally, the plurality of DC voltage regulating modules are integrally located on one side of the plurality of AC rectifier modules, that is, all the DC voltage regulating modules are stacked together, and all the AC rectifier modules are stacked together.

[0123] For example, Figure 9 is a schematic diagram of the structure of another charging host along the Y-axis in this embodiment. In Figure 9, the charging host 90 includes a cabinet 910, multiple AC rectifier modules 920 (such as AC rectifier module 9201, AC rectifier module 9202, AC rectifier module 9203, AC rectifier module 9204, AC rectifier module 9205, and AC rectifier module 9206), and multiple DC voltage regulator modules 930 (such as DC voltage regulator module 9301, DC voltage regulator module 9302, DC voltage regulator module 9303, DC voltage regulator module 9304, DC voltage regulator module 9305, DC voltage regulator module 9306, DC voltage regulator module 9307, DC voltage regulator module 9308, DC voltage regulator module 9309, DC voltage regulator module 9310, DC voltage regulator module 9311, and DC voltage regulator module 9312). The cabinet 910's receiving chamber is divided into a first receiving chamber 9101 and a second receiving chamber 9102 along the Z direction. Multiple AC rectifier modules 920 and multiple DC voltage regulator modules 930 are stacked along the X direction within the first receiving chamber 9101. The DC voltage regulator modules 930 are positioned entirely on one side of the AC rectifier modules 920.

[0124] In this way, since all DC voltage regulation modules are stacked together and all AC rectifier modules are stacked together, this embodiment can quickly and conveniently remove a certain number of DC voltage regulation modules from all DC voltage regulation modules or remove a certain number of AC rectifier modules from all AC rectifier modules without affecting the stacking between other modules.

[0125] Optionally, multiple AC rectifier modules are connected via an AC busbar, which is used to transmit AC power. The AC busbar can be a conductive material used to transmit and distribute AC power, and can be made of copper or aluminum and can be flat or elongated.

[0126] In this way, AC power can be input to multiple AC rectifier modules and AC power can be transmitted between multiple AC rectifier modules through the AC busbar.

[0127] For example, as shown in FIG. 10 , based on FIG. 8 , multiple AC rectifier modules 820 are connected via an AC busbar 1010 .

[0128] Optionally, the AC busbar has a photovoltaic stacking function. Wherein, the AC busbar has a photovoltaic stacking function. It can be understood that the AC busbar can transmit the AC power output by the photovoltaic power generation system.

[0129] As can be seen, the charging device of this embodiment can be connected to a photovoltaic power generation system and convert the AC power output by the photovoltaic power generation system into DC power through the AC rectifier module. In this way, the charging device of this embodiment can use the AC power of the photovoltaic power generation system to charge electric vehicles.

[0130] Optionally, the multiple AC rectifier modules and the multiple DC voltage regulator modules are connected via a DC busbar, which is used to transmit DC power. The DC busbar can be a conductive material used to transmit and distribute DC power, and can be made of copper or aluminum, and can be flat or elongated.

[0131] For example, as shown in FIG11 , based on FIG9 , multiple AC rectifier modules 920 and multiple DC voltage regulation modules are connected via an AC busbar 1110 .

[0132] In this way, the DC power output by the multiple AC rectifier modules can be transmitted to the multiple DC voltage regulation modules through the DC busbar, and the DC power can be transmitted between the multiple DC voltage regulation modules.

[0133] Optionally, the DC busbar has a stacking storage function. The DC busbar having the stacking storage function means that the DC busbar can transmit the DC power output by the energy storage device. The energy storage device is a device that can store DC power.

[0134] As can be seen, the charging device of this embodiment can be connected to the energy storage device and regulate the voltage of the DC power output by the energy storage device through the DC voltage regulator module. In this way, the charging device of this embodiment can use the DC power of the energy storage device to charge the electric vehicle.

[0135] Optionally, a part of the multiple AC rectifier modules and a part of the DC voltage regulation modules in the multiple DC voltage regulation modules are connected through a first DC busbar, and the remaining AC rectifier modules in the multiple AC rectifier modules and the remaining DC voltage regulation modules in the multiple DC voltage regulation modules are connected through a second DC busbar. The first DC busbar and the second DC busbar are used to transmit DC power, and the first DC busbar is different from the second DC busbar.

[0136] For example, as shown in Figure 12, based on Figure 8, a part of the multiple AC rectifier modules 820 and a part of the DC voltage regulation modules in the multiple DC voltage regulation modules 830 are connected through a first DC busbar 1210, and the remaining AC rectifier modules in the multiple AC rectifier modules 820 and the remaining DC voltage regulation modules in the multiple DC voltage regulation modules 830 are connected through a second DC busbar 1220.

[0137] As can be seen, this embodiment can connect some AC rectifier modules and some DC voltage regulator modules via the first DC busbar, and connect the remaining AC rectifier modules and the remaining DC voltage regulator modules via the second DC busbar. In this way, when it is necessary to reduce the number of AC rectifier modules and DC voltage regulator modules, this embodiment can conveniently and quickly adjust the circuit of one of the DC busbars without adjusting the circuit of the other DC busbar, thereby reducing the amount of DC busbar circuit adjustment.

[0138] Optionally, the first DC busbar and / or the second DC busbar has a stacking storage function.

[0139] As can be seen, the charging device of this embodiment can be connected to the energy storage device and regulate the voltage of the DC power output by the energy storage device through the DC voltage regulator module. In this way, the charging device of this embodiment can use the DC power of the energy storage device to charge the electric vehicle.

[0140] Optionally, multiple DC voltage regulation modules are directly plugged into multiple power distribution modules.

[0141] In this way, by directly plugging in, the transmission loss of DC power between multiple DC voltage regulation modules and multiple power distribution modules can be reduced, while the line layout between multiple DC voltage regulation modules and multiple power distribution modules can be reduced, reducing line materials and improving space utilization.

[0142] For example, as shown in Figure 13, based on Figure 8, the charging host 80 also includes multiple power distribution modules 1310 (such as power distribution module 13101, power distribution module 13102, power distribution module 13103, power distribution module 13104, power distribution module 13105 and power distribution module 13106), and the multiple power distribution modules 1310 are stacked along the X direction in the second receiving cavity 8102. Among them, the DC voltage regulation module 8301 and the DC voltage regulation module 8302 are directly plugged into the power distribution module 13101; the DC voltage regulation module 8303 and the DC voltage regulation module 8304 are directly plugged into the power distribution module 13102; the DC voltage regulation module 8305 and the DC voltage regulation module 8306 are directly plugged into the power distribution module 13103; the DC voltage regulation module 8307 and the DC voltage regulation module 8308 are directly plugged into the power distribution module 13104; the DC voltage regulation module 8309 and the DC voltage regulation module 8310 are directly plugged into the power distribution module 13105; and the DC voltage regulation module 8311 and the DC voltage regulation module 8312 are directly plugged into the power distribution module 13106.

[0143] For another example, as shown in Figure 14, based on Figure 9, the charging host 90 also includes multiple power distribution modules 1410 (such as power distribution module 14101, power distribution module 14102, power distribution module 14103, power distribution module 14104, power distribution module 14105 and power distribution module 14106), and the multiple power distribution modules 1410 are stacked along the X direction in the second receiving cavity 9102. Among them, the DC voltage regulation module 9301 and the DC voltage regulation module 9302 are directly plugged into the power distribution module 14101; the DC voltage regulation module 9303 and the DC voltage regulation module 9304 are directly plugged into the power distribution module 14102; the DC voltage regulation module 9305 and the DC voltage regulation module 9306 are directly plugged into the power distribution module 14103; the DC voltage regulation module 9307 and the DC voltage regulation module 9308 are directly plugged into the power distribution module 14104; the DC voltage regulation module 9309 and the DC voltage regulation module 9310 are directly plugged into the power distribution module 14105; and the DC voltage regulation module 9311 and the DC voltage regulation module 9312 are directly plugged into the power distribution module 14106.

[0144] Optionally, the ratio of the number of AC rectifier modules in the multiple AC rectifier modules to the number of DC voltage regulation modules in the multiple DC voltage regulation modules is inversely proportional to the ratio of the power of the multiple AC rectifier modules to the power of the multiple DC voltage regulation modules.

[0145] As can be seen, since the AC rectifier module is used to convert the AC power input to the charging host into DC power, and the DC voltage regulator module is used to adjust the voltage of the DC power output by the AC rectifier module, this embodiment needs to ensure that the ratio of the number of AC rectifier modules to the number of DC voltage regulator modules is inversely proportional to the ratio of the power of the multiple AC rectifier modules to the power of the multiple DC voltage regulator modules. In this way, the number of AC rectifier modules multiplied by the power of the AC rectifier modules can be equal to the number of DC voltage regulator modules multiplied by the power of the DC voltage regulator modules.

[0146] [Scheme 4]

[0147] In "Scheme 4", the charging host mentioned in the above "Scheme 1", "Scheme 2" or "Scheme 3" also includes an AC input module, which can be used to receive AC power and input the AC power into multiple power conversion modules; the AC input module and multiple power distribution modules are stacked along the second direction in the second receiving cavity.

[0148] In this way, the AC input module can realize the input of AC power from the outside to the charging host and the transmission of the AC power to the power conversion module for processing.

[0149] Optionally, a portion of the multiple power distribution modules are located on one side of the AC input module, and the remaining power distribution modules are located on the other side of the AC input module.

[0150] For example, as shown in FIG15 , based on FIG13 , the charging host 80 further includes an AC input module 1510. The AC input module 1510 and multiple power distribution modules 1310 are stacked along the X-direction within the second receiving cavity 8102. Part of the multiple power distribution modules 1310 are located on one side of the AC input module 1510, and the remaining power distribution modules 1310 are located on the other side of the AC input module 1510.

[0151] In this way, when the number of power distribution modules needs to be reduced, this embodiment can quickly and conveniently remove the power distribution module located on one side of the AC input module, avoiding a large number of adjustments to the entire stacked power distribution modules, reducing the adjustment workload and time.

[0152] Optionally, multiple power distribution modules are integrally located on one side of the AC input module, that is, all power distribution modules are stacked on top of each other.

[0153] For example, as shown in FIG16 , based on FIG14 , the charging host 90 further includes an AC input module 1610. The AC input module 1610 and multiple power distribution modules 1410 are stacked along the X-direction within the second receiving cavity 9102. The multiple power distribution modules 1410 are located entirely on one side of the AC input module 1610.

[0154] In this way, since all the power distribution modules are stacked together, this embodiment can quickly and conveniently remove a certain number of power distribution modules from all the power distribution modules without affecting the stacking of other modules.

[0155] [Scheme 5]

[0156] In "Solution 5," the charging host described in "Solution 1," "Solution 2," "Solution 3," or "Solution 4" further includes a liquid cooling module, and the cabinet of the charging host further includes a third receiving chamber, with the liquid cooling module located within the third receiving chamber. The liquid cooling module is configured to exchange heat with the external environment and deliver cooled coolant to the charging host modules via liquid cooling pipes. Thus, the liquid cooling module can dissipate heat from the charging host modules (e.g., the power conversion module, the power distribution module, etc.).

[0157] For example, the liquid cooling module includes components such as a water pump, a heat exchanger, a fan, a kettle, pipes, or a shut-off valve to provide coolant to the charging host and release the heat in the returning coolant to the external environment through heat exchange.

[0158] The positional relationship between the third receiving cavity and the first receiving cavity and the second receiving cavity is described below in the following multiple ways.

[0159] Method 1

[0160] The cabinet's receiving cavity in "Scheme 1" is divided into an upper and lower first receiving cavity and a second receiving cavity along the Z direction, and multiple power conversion modules are stacked in the first receiving cavity along the X direction, and multiple power distribution modules are stacked in the second receiving cavity along the X direction. Therefore, in "Scheme 1", the third receiving cavity can be arranged in sequence with the first receiving cavity and the second receiving cavity along the X direction and spaced apart.

[0161] In this way, since the liquid cooling and heat dissipation module is in the third receiving cavity, the liquid cooling and heat dissipation module, multiple power conversion modules and multiple power distribution modules are all arranged along the X direction to avoid the height of the modular charging host being too high.

[0162] Optionally, the third receiving cavity is on one side or both sides of the first receiving cavity and the second receiving cavity.

[0163] For example, taking the third receiving chamber to one side of the first and second receiving chambers as an example, as shown in FIG17 , based on FIG4 , the cabinet 410 further includes a third receiving chamber 1710, and the third receiving chamber 1710 is sequentially arranged with the first and second receiving chambers 4101 and 4102 along the X-direction and spaced apart. The charging host 40 further includes a liquid cooling and heat dissipation module 1720, and the liquid cooling and heat dissipation module 1720 is located within the third receiving chamber 1710. Thus, the liquid cooling and heat dissipation module 1720, the multiple power conversion modules 420, and the multiple power distribution modules 430 are all arranged along the X-direction.

[0164] For another example, taking the third receiving chamber on both sides of the first and second receiving chambers, as shown in FIG18 , based on FIG4 , the cabinet 410 further includes a third receiving chamber 1810. The third receiving chamber 1810 is sequentially arranged with the first and second receiving chambers 4101 and 4102 along the X-direction and spaced apart from each other. The third receiving chamber 1810 is located on both sides of the first and second receiving chambers 4101 and 4102. The charging host 40 further includes a liquid cooling and heat dissipation module 1820, which is located within the third receiving chamber 1810. Thus, the liquid cooling and heat dissipation module 1820, the multiple power conversion modules 420, and the multiple power distribution modules 430 are all arranged along the X-direction.

[0165] Method 2

[0166] The cabinet's receiving cavity in "Scheme 1" is divided into an upper and lower first receiving cavity and a second receiving cavity along the Z direction. Therefore, in "Method 2", the third receiving cavity can be arranged in sequence with the first receiving cavity and the second receiving cavity along the Z direction and spaced apart.

[0167] Thus, since the liquid cooling and heat dissipation module is in the third receiving chamber, the liquid cooling and heat dissipation module can be arranged on the top of the charging host. In addition, the liquid cooling and heat dissipation module arranged on the top of the charging host can improve the heat dissipation efficiency and reduce the noise generated by the liquid cooling and heat dissipation module.

[0168] Optionally, the third receiving cavity is on one side or both sides of the first receiving cavity and the second receiving cavity.

[0169] For example, taking the third receiving chamber to one side of the first and second receiving chambers as an example, as shown in FIG19 , based on FIG4 , cabinet 410 further includes a third receiving chamber 1910, which is sequentially arranged with first and second receiving chambers 4101 and 4102 along the Z direction and spaced apart. Charging host 40 further includes a liquid cooling and heat dissipation module 1920, which is located within third receiving chamber 1910. Thus, liquid cooling and heat dissipation module 1920 is disposed on top of charging host 40.

[0170] Method Three

[0171] The cabinet's receiving cavity in "Scheme 2" is divided into a front and rear first receiving cavity and a second receiving cavity along the Y direction, and multiple power conversion modules are stacked along the X direction in the first receiving cavity, and multiple power distribution modules are stacked along the X direction in the second receiving cavity. Therefore, in "Scheme 3", the third receiving cavity can be arranged in sequence with the first receiving cavity and the second receiving cavity along the X direction and spaced apart.

[0172] In this way, since the liquid cooling and heat dissipation module is in the third receiving cavity, the liquid cooling and heat dissipation module, multiple power conversion modules and multiple power distribution modules are all arranged along the X direction to avoid the height of the modular charging host being too high.

[0173] Optionally, the third receiving cavity is on one side or both sides of the first receiving cavity and the second receiving cavity.

[0174] For example, taking the third receiving chamber to one side of the first and second receiving chambers as an example, as shown in FIG20 , based on FIG7 , the cabinet 710 further includes a third receiving chamber 2010, and the third receiving chamber 2010 is sequentially arranged with the first and second receiving chambers 7101 and 7102 along the X-direction and spaced apart. The charging host 70 further includes a liquid cooling and heat dissipation module 2020, and the liquid cooling and heat dissipation module 2020 is located within the third receiving chamber 2010. Thus, the liquid cooling and heat dissipation module 2020, the multiple power conversion modules 720, and the multiple power distribution modules 730 are all arranged along the X-direction.

[0175] Method 4

[0176] The cabinet's receiving cavity in "Scheme 2" is divided into a front and rear first receiving cavity and a second receiving cavity along the Y direction. Therefore, in "Method 4", the third receiving cavity can be arranged in sequence with the first receiving cavity and the second receiving cavity along the Z direction and spaced apart.

[0177] Thus, since the liquid cooling and heat dissipation module is in the third receiving chamber, the liquid cooling and heat dissipation module can be arranged on the top of the charging host. In addition, the liquid cooling and heat dissipation module arranged on the top of the charging host can improve the heat dissipation efficiency and reduce the noise generated by the liquid cooling and heat dissipation module.

[0178] Optionally, the third receiving cavity is on one side or both sides of the first receiving cavity and the second receiving cavity.

[0179] [Scheme 6]

[0180] In Solution 6, the cabinet of the charging host described in Solution 1, Solution 2, Solution 3, Solution 4, or Solution 5 may include multiple doors. Thus, the multiple doors can open the interior space of the cabinet, making it easier to install the modules inside the cabinet.

[0181] It should be noted that the multiple doors can be opened by stretching outward, or by sliding the doors up and down, or by sliding the doors left and right, etc. In addition, the multiple doors can be retractable, or non-retractable, etc.

[0182] Optionally, multiple cabinet doors can be arranged relatively along the X direction or the Y direction. In this way, the cabinet doors can be opened from the Y direction in this embodiment to view the modules stacked along the X direction.

[0183] For example, as shown in FIG21 , based on FIG4 , cabinet 410 includes cabinet door 2111, cabinet door 2112, cabinet door 2113, and cabinet door 2114. Cabinet door 2111 and cabinet door 2114 are arranged opposite to each other along the X direction, cabinet door 2112 and cabinet door 2113 are arranged opposite to each other along the X direction, cabinet door 2111 and cabinet door 2113 are arranged opposite to each other along the Y direction, and cabinet door 2113 and cabinet door 2114 are arranged opposite to each other along the Y direction.

[0184] For another example, as shown in FIG22 , based on FIG4 , the cabinet 410 includes a cabinet door 2211 and a cabinet door 2212. The cabinet door 2211 and the cabinet door 2212 are arranged opposite to each other along the X direction.

[0185] [Scheme 7]

[0186] In "Solution 7", the charging host mentioned in the above "Solution 1", "Solution 2", "Solution 3", "Solution 4", "Solution 5" or "Solution 6" is in the charging device, and the charging device also includes at least one charging terminal.

[0187] In a specific implementation, the charging host also includes a charging connection module, which is used to connect the charging host to at least one charging terminal; the cabinet also includes a fourth receiving cavity, which is arranged in sequence with the first receiving cavity and the second receiving cavity along the X direction and is spaced apart, and the charging connection module is located in the fourth receiving cavity.

[0188] For example, as shown in Figure 23, based on Figure 17, the cabinet 410 further includes a fourth receiving cavity 2310, which is sequentially arranged and spaced apart from the first receiving cavity 4101, the second receiving cavity 4102, and the third receiving cavity 1710 along the X-direction. The charging host 40 further includes a charging connection module 2320, which is located within the fourth receiving cavity 2310. Thus, the charging connection module 2320, the liquid cooling and heat dissipation module 1720, the multiple power conversion modules 420, and the multiple power distribution modules 430 are all arranged along the X-direction.

[0189] In this way, the charging host can be connected to at least one charging terminal through the charging connection module, so as to form an integrated charging device integrating the charging host and the charging terminal.

[0190] Optionally, the charging connection module is respectively connected to multiple power distribution modules and at least one charging terminal.

[0191] Optionally, the charging connection module includes charging-related components such as contactors, fuse protection, current detection, and charging control boards.

[0192] Optionally, the charging device further comprises a screen, which is arranged on a first outer side of the cabinet, with the first outer side facing the direction X. In this way, relevant power parameters of the charging device can be viewed through the screen.

[0194] Optionally, at least one charging terminal includes at least one charging gun; the at least one charging gun is disposed on a first outer side of the cabinet, with the first outer side facing the X direction. In this way, the at least one charging gun can be used to connect to and charge the electric vehicle.
