Abstract

The present application relates to the technical field of energy, and discloses a charging device. 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.

Charging device

[0001] This application claims priority to Chinese Patent Application No. 202420143382.2, filed on January 19, 2024, entitled “Charging Device”, the entire contents of which are incorporated herein by reference. Technical Field

[0002] This application relates to the field of energy technology, and more particularly to a charging device. Background Technology

[0003] With the rapid development of the new energy vehicle industry, the charging power of electric vehicles is gradually increasing, and charging demands are becoming more diversified. To meet the charging needs of different vehicles and improve power utilization, modular charging units have gained attention and development.

[0004] Currently, most modular charging units adopt an architecture of vertically stacked modules with a top-mounted air-liquid heat exchanger. In other words, the modules in the charging unit are stacked vertically, and the air-liquid heat exchanger is placed on top of the charging unit. However, the more modules stacked vertically in this architecture, the taller the overall modular charging unit becomes, making it impossible to place it in locations with height restrictions.

[0005] [Revised according to Article 91, February 2025] Summary of the Invention

[0006] Firstly, this application provides a charging device comprising a charging host, which includes a cabinet, multiple power conversion modules, and multiple power distribution modules. The cabinet includes a first receiving cavity and a second receiving cavity, which are arranged sequentially and spaced apart along a first direction. The multiple power conversion modules convert input AC power into DC power. The multiple power distribution modules distribute the DC power output from the multiple power conversion modules. The multiple power conversion modules are stacked within the first receiving cavity along a second direction, which is different from the second direction. The multiple power distribution modules are stacked within the second receiving cavity along the second direction.

[0007] As can be seen, this embodiment divides the receiving cavity of the charging host cabinet into a first receiving cavity and a second receiving cavity along a first direction. Multiple power conversion modules of the charging host are stacked in the first receiving cavity along a second direction, and multiple power distribution modules of the charging host are stacked in the second receiving cavity along a second direction. Since the first and second receiving cavities are different, the multiple power conversion modules and multiple power distribution modules can be stacked in different spaces. Furthermore, the multiple power conversion modules and multiple power distribution modules are stacked along the same direction, but the stacking direction is different from the arrangement direction of the receiving cavities. Therefore, this embodiment can minimize the shortcomings caused by the stacking direction being the same as the arrangement direction of the receiving cavities. For example, when the stacking direction is the same as the arrangement direction of the receiving cavities and is both longitudinal or vertical, this would result in an excessively high overall height of the charging host.

[0008] Optionally, the first direction is vertical or longitudinal, and the second direction is horizontal or transverse. In this embodiment, the stacking direction of the multiple power conversion modules and multiple power distribution modules in the charging host can be changed from vertical to horizontal. That is, the multiple power conversion modules and multiple power distribution modules are changed from being stacked vertically to being stacked horizontally. By changing the stacking direction of the multiple power conversion modules and multiple power distribution modules, the height of the charging host can be minimized.

[0009] Optionally, the first direction is either the Z or Y direction in a three-dimensional coordinate system, and the second direction is the X direction in a three-dimensional coordinate system. This way, by setting the stacking direction of multiple power conversion modules and 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 within the first receiving cavity; multiple power distribution modules are stacked in a single row or multiple rows along the second direction within the second receiving cavity.

[0011] Thus, this application allows for flexible configuration within the cabinet's receiving cavity, enabling the stacking of multiple power conversion modules or power distribution modules in a single or multiple rows as needed. Specifically, when multiple power conversion modules or power distribution modules are stacked in a single row, this embodiment allows for simple and rapid stacking of these modules. When multiple power conversion modules or power distribution modules are stacked in multiple rows, this embodiment allows for the placement of more power conversion modules or power distribution modules within a limited cabinet space, improving space utilization.

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

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

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

[0015] Thus, when it is necessary to reduce the number of DC voltage regulation modules, this embodiment can quickly and easily remove the DC voltage regulation module located on one side of multiple AC rectifier modules, avoiding extensive adjustments to the entire stacked power conversion module and reducing the workload and time required for adjustments.

[0016] Optionally, multiple DC voltage regulating modules can be located on one side of multiple AC rectifier modules.

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

[0018] Optionally, multiple AC rectifier modules can be 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 (PV) superposition function. This means the AC busbar can transmit the AC power output from the photovoltaic power generation system.

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

[0022] Optionally, multiple AC rectifier modules and 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 from multiple AC rectifier modules can be transmitted to multiple DC voltage regulator modules, and DC power can be transmitted between multiple DC voltage regulator modules, through the DC bus.

[0024] Optionally, the DC busbar has a stacking energy storage function. This means the DC busbar can transmit the DC power output from the energy storage device. The energy storage device is a device capable of storing DC power.

[0025] As can be seen, the charging device in this embodiment can be connected to an energy storage device, and the voltage of the DC power output by the energy storage device can be regulated by a DC voltage regulation module. Thus, the charging device in this embodiment can use the DC power from the energy storage device to charge electric vehicles.

[0026] Optionally, a portion of the AC rectifier modules and a portion of the DC voltage regulator modules are connected via a first DC bus, and the remaining AC rectifier modules and the remaining DC voltage regulator modules are connected via a second DC bus. The first and second DC buses are used to transmit DC power, and the first and second DC buses are different.

[0027] As can be seen, this embodiment connects a portion of the AC rectifier modules and a portion of the DC voltage regulator modules via a first DC bus, and connects the remaining AC rectifier modules and the remaining DC voltage regulator modules via a second DC bus. Thus, when it is necessary to reduce the number of AC rectifier modules and DC voltage regulator modules, this embodiment allows for convenient and quick adjustment of the wiring on one of the DC buses without needing to adjust the wiring on the other DC bus, reducing the amount of wiring adjustment required for the DC buses.

[0028] Optionally, the first DC bus and / or the second DC bus may have a stacking storage function.

[0029] As can be seen, the charging device in this embodiment can be connected to an energy storage device, and the voltage of the DC power output by the energy storage device can be regulated by a DC voltage regulation module. Thus, the charging device in this embodiment can use the DC power from the energy storage device to charge electric vehicles.

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

[0031] In this way, direct plugging can reduce the transmission loss of DC power between multiple DC voltage regulation modules and multiple power distribution modules, while reducing the wiring layout between multiple DC voltage regulation modules and multiple power distribution modules, reducing wiring materials and improving space utilization.

[0032] Optionally, the ratio of the number of AC rectifier modules in the plurality of AC rectifier modules to the number of DC voltage regulator modules in the plurality of DC voltage regulator modules is inversely proportional to the ratio of the power of the plurality of AC rectifier modules to the power of the plurality of DC voltage regulator 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. Thus, 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 also includes an AC input module for receiving AC power and inputting the AC power into multiple power conversion modules; the AC input module and the multiple power distribution modules are stacked along a second direction within a second receiving cavity.

[0035] In this way, the AC input module enables external AC power to be input into the charging host and the AC power to be transmitted to the power conversion module for processing.

[0036] Optionally, some of the 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] Thus, when it is necessary to reduce the number of power distribution modules, this embodiment can quickly and easily remove the power distribution module located on one side of the AC input module, avoiding extensive adjustments to the entire stacked power distribution module and reducing the workload and time required for adjustments.

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

[0039] In this way, since all power distribution modules are stacked together, this embodiment can quickly and easily remove a certain number of power distribution modules from all 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 liquid cooling pipes; the cabinet also includes a third receiving cavity, which is arranged sequentially and spaced apart from the first receiving cavity and the second receiving cavity along the first direction or the second direction; the liquid cooling heat dissipation module is located in the third receiving cavity.

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

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

[0043] In this way, the position of the liquid cooling heat dissipation module in the cabinet can be flexibly set.

[0044] Optionally, the cabinet unit includes multiple cabinet doors, which are arranged opposite each other along a first or second direction.

[0045] In this way, the internal space of the cabinet can be opened through multiple cabinet doors, making it convenient to set up the modules inside the cabinet.

[0046] Optionally, the charging device further includes at least one charging terminal, which is used to output DC power allocated by multiple power distribution modules; the charging host further includes a charging connection module, which is used to connect the charging host to at least one charging terminal; the cabinet further includes a fourth receiving cavity, which is arranged sequentially and spaced apart from the first receiving cavity and the second receiving cavity along a second direction; the charging connection module is located in the fourth receiving cavity.

[0047] In this way, the charging connection module can connect the charging host to at least one charging terminal to form an integrated charging device that combines the charging host and the charging terminal.

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

[0049] In this way, it is possible to connect to and charge electric vehicles using at least one charging gun. Attached Figure Description

[0075] To better understand the technical solutions of this application, the technical solutions of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the description of the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0076] It should be understood that the terms "first," "second," etc., used in this application are used to distinguish different objects, not to describe a specific order. Furthermore, the terms "comprising" and "having," and any variations thereof, are intended to cover non-exclusive inclusion. For example, a process, method, software, product, or apparatus that includes a series of steps or units is not limited to the listed steps or units, but also includes steps or units not listed, or other steps or units inherent to such processes, methods, products, or apparatus.

[0077] The term "embodiment" in this application means that a specific feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of this application. The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with 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 there can be three types of relationships. For example, A and / or B can represent the following three cases: "A", "B", and "A and B". Among them, A and B can be singular or plural.

[0079] In this application's embodiments, the symbol " / " can indicate that the preceding and following objects are in an "or" relationship. Additionally, the symbol " / " can also represent a division sign, i.e., performing a division operation. For example, A / B can mean A divided by B.

[0080] In the embodiments of this application, "at least one item" or its similar expression refers to any combination of these items, including any combination of a single item or a plurality of items, meaning one or more; "multiple items" means two or more. For example, at least one item of a, b, or c can represent the following seven cases: "a", "b", "c", "a and b", "a and c", "b and c", and "a, b, and c". Each of a, b, and c can be an element or a set containing one or more elements.

[0081] In the embodiments of this application, "coupling" and "connection" can be used to refer to electrical connections, which may include direct connections via wires or connection terminals or indirect connections via other devices (such as inductors, capacitors, or resistors). Therefore, "coupling" and "connection" can be considered as a broad type of electronic communication connection. Furthermore, the mutual coupling / direct coupling / connection shown or discussed may be indirect coupling or connection through interfaces, devices, units, or components, and may be communication, electrical, or other forms.

[0082] The circuits or other components in the embodiments of this application may be described as "used for" performing one or more tasks. In this context, "used for" can imply a structure (e.g., a circuit system) that indicates the circuit / component includes a structure that performs one or more tasks during operation. Therefore, even when the specified circuit / component is currently inoperable, it can still be referred to as "used for performing the task." Circuits / components used with the term "used for" include hardware, such as circuits that perform operations.

[0083] A charging device is a device that converts alternating current (AC) into direct current (DC) and provides charging for electric vehicles.

[0084] Optionally, the charging device may include a charging host and a charging terminal. That is, the charging device may be an integrated charging device that combines the charging host and the charging terminal.

[0085] A charging host is a device that converts alternating current (AC) to direct current (DC), regulates the voltage of the DC power, and then distributes the regulated DC power; in other words, it is a power conversion and distribution device. It typically includes components such as rectifiers, filters, transformers, and inverters.

[0086] A charging terminal is a device that receives direct current (DC) output from a charging host and connects to charge an electric vehicle. It typically includes a socket, connecting cables, and associated control circuitry. Users can insert the electric vehicle's charging plug into the charging terminal's socket and connect the charging terminal to the electric vehicle via the connecting cables.

[0087] The following is an example illustrating the charging scenario provided by the charging device. Figure 1 is a schematic diagram of a charging scenario according to this embodiment. In Figure 1, the charging device 110 can be applied to a scenario of charging an electric vehicle 120. The input terminal of the charging device 110 can be connected to the power grid 130, and the output terminal of the charging device 110 can be connected to the electric vehicle 120. The charging device 110 can convert the alternating current (AC) in the power grid 130 into direct current (DC), and after voltage regulation, distribute the DC power to the electric vehicle 120, thereby charging the electric vehicle 120. The electrical energy in the power grid 130 can be industrial electricity or residential electricity, etc.

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

[0089] For example, regarding the modularization of the power conversion function of the charging device, this embodiment can introduce a power conversion module. This module converts AC power to DC power and regulates the DC voltage. The power conversion module can be called a power module. Furthermore, there can be multiple power conversion modules, and the number can be adjusted as needed to adjust the power conversion capability of the charging device. Generally, the more power conversion modules there are, the greater the power conversion capability of the charging device.

[0090] For example, regarding the modularization of the power distribution function of the charging device, this embodiment can introduce a power distribution module. This module distributes the DC power regulated by the power conversion module to the charging terminal. The power distribution module can be referred to as a power matrix. Furthermore, there can be multiple power distribution modules, and the number can be continuously adjusted as needed to adjust the power distribution capability of the charging device. Generally, the more power distribution modules there are, the greater the power distribution capability of the charging device.

[0091] The modularity 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, etc.) and multiple power distribution modules (such as power distribution module 2121, power distribution module 2122 and power distribution module 2123, etc.).

[0092] Currently, modular charging units often employ a vertically stacked module architecture with a top-mounted air-liquid heat exchanger. In other words, the modules in the charging unit are stacked vertically, and the air-liquid heat exchanger is placed on top of the charging unit. However, the more modules are stacked vertically in this architecture, the taller the overall modular charging unit becomes, making it impossible to place it in locations with height restrictions.

[0093] For example, taking the vertical direction as the Z-direction in a three-dimensional coordinate system, Figure 3 is a schematic diagram of a modular charging host architecture using vertically stacked modules in this embodiment. In Figure 3, the charging host 30 includes a cabinet 310, multiple power conversion modules 320 (such as power conversion modules 3201, 3202, 3203, 3204, 3205, and 3206, etc.), and a wind-liquid heat exchanger 330. The multiple power conversion modules are stacked sequentially from bottom to top along the Z-direction, and the wind-liquid heat exchanger 330 is placed on top of the cabinet 310. Thus, for high-power scenarios, this architecture requires more power conversion modules, and more power conversion modules will result in a higher overall height of the charging host 30, making it impossible to place the charging host 30 in height-restricted areas.

[0094] Since the modular charging host adopts a vertical stacking of modules and the top-mounted air-liquid heat exchanger architecture is not suitable for places with height restrictions, this embodiment needs to optimize the direction of module stacking in order to avoid the modular charging host from being too tall as much as possible.

[0095] In the following embodiment, the "modular charging host" will be referred to as the "charging host" for short, and the following examples illustrate how to optimize the direction of module stacking through various schemes. The same content between different schemes can be referenced by each other, which will not be repeated here.

[0096] Option 1

[0097] In "Solution 1", this embodiment changes the stacking direction of the multiple power conversion modules and multiple power distribution modules in the charging host from the original vertical stacking to horizontal stacking. That is, the multiple power conversion modules and multiple power distribution modules are changed from being stacked vertically to being stacked horizontally. In this way, by changing the stacking direction of the multiple power conversion modules and multiple power distribution modules, the height of the modular charging host is minimized.

[0098] The following embodiment uses the vertical direction as the Z direction in the three-dimensional coordinate system and the horizontal direction as the X direction in the three-dimensional coordinate system as an example for specific explanation.

[0099] In "Solution 1", this embodiment divides the receiving cavity of the charging host cabinet into two receiving cavities (referred to as "first receiving cavity" and "second receiving cavity" for ease of description) along the Z direction (for ease of description, the "Z direction" can be referred to as the "first direction"). Multiple power conversion modules are then placed in the first receiving cavity, and multiple power distribution modules are placed in the second receiving cavity. Specifically, 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" 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 modules 4201, 4202, 4203, 4204, 4205, and 4206, etc.) and multiple power distribution modules 430 (such as power distribution modules 4301, 4302, 4303, 4304, 4305, and 4306). The receiving cavity of the cabinet 410 is divided into an upper and lower first receiving cavity 4101 and a second receiving cavity 4102 along the Z direction. The multiple power conversion modules 420 are stacked along the X direction in the first receiving cavity 4101, and the multiple power distribution modules 430 are stacked along the X direction in the second receiving cavity 4102.

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

[0102] Thus, this embodiment allows for flexible configuration within the cabinet's receiving cavity, enabling the stacking of multiple power conversion modules or power distribution modules in a single or multiple rows as needed. When multiple power conversion modules or power distribution modules are stacked in a single row, this embodiment allows for simple and rapid stacking. When multiple power conversion modules or power distribution modules are stacked in multiple rows, this embodiment allows for the placement of more power conversion modules or power distribution modules within a limited cabinet space, improving space utilization.

[0103] For example, in Figure 4, 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 example, Figure 5 is a top view of a charging host according to this embodiment. In Figure 5, the charging host 50 includes a cabinet 510 and multiple power conversion modules 520 (such as power conversion modules 5201, 5202, 5203, 5204, 5205, and 5206). The multiple power conversion modules 520 are stacked in a single row along the X direction within the first receiving cavity 4101 of the cabinet 510.

[0105] For example, Figure 6 is a top view of another charging host in this embodiment 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 modules 6201, 6202, 6203, 6204, 6205, 6206, 6207, 6208, 6209, 6210, 6211, and 6212, etc.). 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 modules 6201, 6202, 6203, 6204, 6205 and 6206 are stacked in a row, and power conversion modules 6207, 6208, 6209, 6210, 6211 and 6212 are stacked in a row.

[0106] Option 2

[0107] In "Solution 2", this embodiment changes the stacking direction of the multiple power conversion modules and multiple power distribution modules in the charging host from the original vertical stacking to horizontal stacking. That is, the multiple power conversion modules and multiple power distribution modules are changed from being stacked vertically to being stacked horizontally. In this way, by changing the stacking direction of the multiple power conversion modules and multiple power distribution modules, the height of the modular charging host is minimized.

[0108] The following embodiment uses the vertical direction as the Z direction in the three-dimensional coordinate system and the horizontal direction as the X direction in the three-dimensional coordinate system as an example for specific explanation.

[0109] In "Solution 2", this embodiment divides the charging host's cabinet cavity into two cavities (referred to as the "first cavity" and the "second cavity") along the Y-direction (for ease of description, the "Y-direction" can be called the "first direction"). Multiple power conversion modules are placed in the first cavity, and multiple power distribution modules are placed in the second cavity. Specifically, the power conversion modules are stacked along the X-direction in the first cavity, and the power distribution modules are stacked along the X-direction in the second cavity (for ease of description, the "X-direction" can be called the "second direction").

[0110] For example, Figure 7 is a schematic diagram of another charging host structure according to this embodiment. In Figure 7, the charging host 70 includes a cabinet 710, multiple power conversion modules 720 (such as power conversion modules 7201, 7202, 7203, 7204, 7205, and 7206, etc.) and multiple power distribution modules 730 (such as power distribution modules 7301, 7302, 7303, 7304, 7305, and 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. The multiple power conversion modules 720 are stacked along the X direction in the first receiving cavity 7101, and the multiple power distribution modules 730 are stacked along the X direction in the second receiving cavity 7102.

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

[0112] Thus, this embodiment allows for flexible configuration within the cabinet's receiving cavity, enabling the stacking of multiple power conversion modules or power distribution modules in a single or multiple rows as needed. When multiple power conversion modules or power distribution modules are stacked in a single row, this embodiment allows for simple and rapid stacking. When multiple power conversion modules or power distribution modules are stacked in multiple rows, this embodiment allows for the placement of more power conversion modules or power distribution modules within a limited cabinet space, improving space utilization.

[0113] Option 3

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

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

[0116] Multiple AC rectifier modules can be used to convert the AC power input to the charging host into DC power. These AC rectifier modules may include AC / DC converters.

[0117] Multiple DC voltage regulator modules can be used to adjust the voltage of the DC power output from multiple AC rectifier modules. These DC voltage regulator modules may include DC / DC converters.

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

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

[0120] For example, Figure 8 is a structural schematic diagram of a charging host along the Y-axis of this embodiment. In Figure 8, the charging host 80 includes a cabinet 810, multiple AC rectifier modules 820 (such as AC rectifier modules 8201, 8202, 8203, 8204, 8205, and 8206) and multiple DC voltage regulator modules 830 (such as DC voltage regulator modules 8301, 8302, 8303, 8304, 8305, 8306, 8307, 8308, 8309, 8310, 8311, and 8312). The receiving cavity of the cabinet 810 is divided into an upper and lower 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 a first receiving cavity 8101. A portion of the DC voltage regulator modules 830 are located on one side of the multiple AC rectifier modules 820, while the remaining DC voltage regulator modules 830 are located on the other side of the multiple AC rectifier modules 820.

[0121] Thus, when it is necessary to reduce the number of DC voltage regulation modules, this embodiment can quickly and easily remove the DC voltage regulation module located on one side of multiple AC rectifier modules, avoiding extensive adjustments to the entire stacked power conversion module and reducing the workload and time required for adjustments.

[0122] Optionally, multiple DC voltage regulator modules are located on one side of multiple AC rectifier modules. That is, all DC voltage regulator modules are stacked together, and all AC rectifier modules are stacked together.

[0123] For example, Figure 9 is a structural schematic diagram of another charging host along the Y-axis of 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, etc.). The cabinet 910 has a receiving cavity divided into an upper and lower first receiving cavity 9101 and a second receiving cavity 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 cavity 9101. The multiple DC voltage regulator modules 930 are located on one side of the multiple AC rectifier modules 920.

[0124] In this way, since all DC voltage regulator modules are stacked together and all AC rectifier modules are stacked together, this embodiment can quickly and easily remove a certain number of DC voltage regulator modules or a certain number of AC rectifier modules from all DC voltage regulator modules without affecting the stacking of 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 for transmitting and distributing AC power, and can be made of copper or aluminum, and can have a flat or elongated shape.

[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 Figure 10, based on Figure 8, multiple AC rectifier modules 820 are connected through AC busbar 1010.

[0128] Optionally, the AC busbar has a photovoltaic (PV) superposition function. This means the AC busbar can transmit the AC power output from the photovoltaic power generation system.

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

[0130] Optionally, multiple AC rectifier modules and 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 for transmitting and distributing DC power; it can be made of copper or aluminum and can be flat or elongated in shape.

[0131] For example, as shown in Figure 11, based on Figure 9, multiple AC rectifier modules 920 and multiple DC voltage regulator modules are connected through AC busbar 1110.

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

[0133] Optionally, the DC busbar has a stacking energy storage function. This means the DC busbar can transmit the DC power output from the energy storage device. The energy storage device is a device capable of storing DC power.

[0134] As can be seen, the charging device in this embodiment can be connected to an energy storage device, and the voltage of the DC power output by the energy storage device can be regulated by a DC voltage regulation module. Thus, the charging device in this embodiment can use the DC power from the energy storage device to charge electric vehicles.

[0135] Optionally, a portion of the AC rectifier modules and a portion of the DC voltage regulator modules are connected via a first DC bus, and the remaining AC rectifier modules and the remaining DC voltage regulator modules are connected via a second DC bus. The first and second DC buses are used to transmit DC power, and the first and second DC buses are different.

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

[0137] As can be seen, this embodiment connects a portion of the AC rectifier modules and a portion of the DC voltage regulator modules via a first DC bus, and connects the remaining AC rectifier modules and the remaining DC voltage regulator modules via a second DC bus. Thus, when it is necessary to reduce the number of AC rectifier modules and DC voltage regulator modules, this embodiment allows for convenient and quick adjustment of the wiring on one of the DC buses without needing to adjust the wiring on the other DC bus, reducing the amount of wiring adjustment required for the DC buses.

[0138] Optionally, the first DC bus and / or the second DC bus may have a stacking storage function.

[0139] As can be seen, the charging device in this embodiment can be connected to an energy storage device, and the voltage of the DC power output by the energy storage device can be regulated by a DC voltage regulation module. Thus, the charging device in this embodiment can use the DC power from the energy storage device to charge electric vehicles.

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

[0141] In this way, direct plugging can reduce the transmission loss of DC power between multiple DC voltage regulation modules and multiple power distribution modules, while reducing the wiring layout between multiple DC voltage regulation modules and multiple power distribution modules, reducing wiring 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. Specifically, DC voltage regulator modules 8301 and 8302 are directly plugged into power distribution module 13101; DC voltage regulator modules 8303 and 8304 are directly plugged into power distribution module 13102; DC voltage regulator modules 8305 and 8306 are directly plugged into power distribution module 13103; DC voltage regulator modules 8307 and 8308 are directly plugged into power distribution module 13104; DC voltage regulator modules 8309 and 8310 are directly plugged into power distribution module 13105; and DC voltage regulator modules 8311 and 8312 are directly plugged into power distribution module 13106.

[0143] For 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. Specifically, DC voltage regulator modules 9301 and 9302 are directly plugged into power distribution module 14101; DC voltage regulator modules 9303 and 9304 are directly plugged into power distribution module 14102; DC voltage regulator modules 9305 and 9306 are directly plugged into power distribution module 14103; DC voltage regulator modules 9307 and 9308 are directly plugged into power distribution module 14104; DC voltage regulator modules 9309 and 9310 are directly plugged into power distribution module 14105; and DC voltage regulator modules 9311 and 9312 are directly plugged into power distribution module 14106.

[0144] Optionally, the ratio of the number of AC rectifier modules in the plurality of AC rectifier modules to the number of DC voltage regulator modules in the plurality of DC voltage regulator modules is inversely proportional to the ratio of the power of the plurality of AC rectifier modules to the power of the plurality of DC voltage regulator 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. Thus, 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] Option 4

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

[0148] In this way, the AC input module enables external AC power to be input into the charging host and the AC power to be transmitted to the power conversion module for processing.

[0149] Optionally, some of the 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 Figure 15, based on Figure 13, the charging host 80 also 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. A portion of the power distribution modules 1310 are located on one side of the AC input module 1510, while the remaining power distribution modules are located on the other side of the AC input module 1510.

[0151] Thus, when it is necessary to reduce the number of power distribution modules, this embodiment can quickly and easily remove the power distribution module located on one side of the AC input module, avoiding extensive adjustments to the entire stacked power distribution module and reducing the workload and time required for adjustments.

[0152] Optionally, multiple power distribution modules can be located on one side of the AC input module. In other words, all power distribution modules are stacked together.

[0153] For example, as shown in Figure 16, based on Figure 14, the charging host 90 also 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 generally located on one side of the AC input module 1610.

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

[0155] Option 5

[0156] In "Scheme 5", the charging host mentioned in "Scheme 1", "Scheme 2", "Scheme 3" or "Scheme 4" also includes a liquid cooling heat dissipation module, and the cabinet of the charging host also includes a third receiving cavity, with the liquid cooling heat dissipation module located within the third receiving cavity. The liquid cooling heat dissipation module is used for heat exchange with the external environment and delivers cooled coolant to the modules of the charging host through liquid cooling pipes. In this way, the liquid cooling heat dissipation module can dissipate heat from the modules of the charging host (such as the power conversion module, power distribution module, etc.).

[0157] For example, a liquid cooling heat dissipation module includes components such as a water pump, heat exchanger, fan, kettle, pipes, or 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, the first receiving cavity, and the second receiving cavity is explained in the following ways.

[0159] Method 1

[0160] In “Scheme 1”, the cabinet’s receiving cavity is divided into upper and lower first receiving cavities and second receiving cavities along the Z direction. 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 sequentially and spaced apart from the first and second receiving cavities along the X direction.

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

[0162] Optionally, the third receiving cavity may be located on one or both sides of the first and second receiving cavities.

[0163] For example, taking the third receiving cavity as an example on one side of the first and second receiving cavities, as shown in Figure 17, based on Figure 4, the cabinet 410 further includes a third receiving cavity 1710, and the third receiving cavity 1710, the first receiving cavity 4101, and the second receiving cavity 4102 are arranged sequentially along the X direction and spaced apart. The charging host 40 also includes a liquid cooling heat dissipation module 1720, and the liquid cooling heat dissipation module 1720 is located inside the third receiving cavity 1710. Thus, the liquid cooling 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 example, taking the third receiving cavity as being located on both sides of the first and second receiving cavities, as shown in Figure 18, based on Figure 4, the cabinet 410 further includes a third receiving cavity 1810. The third receiving cavity 1810, the first receiving cavity 4101, and the second receiving cavity 4102 are arranged sequentially along the X direction and spaced apart, with the third receiving cavity 1810 located on both sides of the first and second receiving cavities 4101 and 4102. The charging host 40 also includes a liquid cooling heat dissipation module 1820, which is located within the third receiving cavity 1810. Thus, the liquid cooling 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 Two

[0166] In "Scheme 1", the cabinet's receiving cavity is divided into upper and lower first receiving cavities and second receiving cavities along the Z direction. Therefore, in "Scheme 2", the third receiving cavity can be arranged sequentially and spaced apart from the first and second receiving cavities along the Z direction.

[0167] Thus, since the liquid cooling module is located within the third receiving cavity, it can be positioned on top of the charging unit. Furthermore, positioning the liquid cooling module on top of the charging unit improves heat dissipation efficiency and reduces the noise generated by the liquid cooling module.

[0168] Optionally, the third receiving cavity may be located on one or both sides of the first and second receiving cavities.

[0169] For example, taking the third receiving cavity as an example located on one side of the first and second receiving cavities, as shown in Figure 19, based on Figure 4, the cabinet 410 further includes a third receiving cavity 1910, and the third receiving cavity 1910, the first receiving cavity 4101, and the second receiving cavity 4102 are arranged sequentially along the Z direction and spaced apart. The charging host 40 also includes a liquid cooling heat dissipation module 1920, and the liquid cooling heat dissipation module 1920 is located inside the third receiving cavity 1910. Thus, the liquid cooling heat dissipation module 1920 is located on the top of the charging host 40.

[0170] Method Three

[0171] In “Scheme 2”, the cabinet’s receiving cavity is divided into a front and rear first receiving cavity and a second receiving cavity along the Y direction. 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 3”, the third receiving cavity can be arranged sequentially and spaced apart from the first and second receiving cavities along the X direction.

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

[0173] Optionally, the third receiving cavity may be located on one or both sides of the first and second receiving cavities.

[0174] For example, taking the third receiving cavity as an example on one side of the first and second receiving cavities, as shown in Figure 20, based on Figure 7, the cabinet 710 further includes a third receiving cavity 2010, and the third receiving cavity 2010, the first receiving cavity 7101, and the second receiving cavity 7102 are arranged sequentially along the X direction and spaced apart. The charging host 70 also includes a liquid cooling heat dissipation module 2020, and the liquid cooling heat dissipation module 2020 is located inside the third receiving cavity 2010. Thus, the liquid cooling 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 Four

[0176] In “Scheme 2”, the cabinet’s receiving cavity is divided into a front and rear first receiving cavity and a second receiving cavity along the Y direction. Therefore, in “Scheme 4”, the third receiving cavity can be arranged sequentially and spaced apart from the first and second receiving cavities along the Z direction.

[0177] Thus, since the liquid cooling module is located within the third receiving cavity, it can be positioned on top of the charging unit. Furthermore, positioning the liquid cooling module on top of the charging unit improves heat dissipation efficiency and reduces the noise generated by the liquid cooling module.

[0178] Optionally, the third receiving cavity may be located on one or both sides of the first and second receiving cavities.

[0179] Option 6

[0180] In "Option 6", the cabinet of the charging host mentioned in "Option 1", "Option 2", "Option 3", "Option 4" or "Option 5" can include multiple cabinet doors. In this way, the internal space of the cabinet can be opened through multiple cabinet doors to facilitate the installation of the modules inside the cabinet.

[0181] It should be noted that multiple cabinet doors can be opened by pulling them outwards, sliding them up and down, or sliding them left and right. Additionally, these cabinet doors can be retractable or non-retractable.

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

[0183] For example, as shown in Figure 21, based on Figure 4, the cabinet 410 includes cabinet doors 2111, 2112, 2113, and 2114. Cabinet doors 2111 and 2114 are positioned opposite each other along the X-direction, cabinet doors 2112 and 2113 are positioned opposite each other along the X-direction, cabinet doors 2111 and 2113 are positioned opposite each other along the Y-direction, and cabinet doors 2113 and 2114 are positioned opposite each other along the Y-direction.

[0184] For example, as shown in Figure 22, based on Figure 4, the cabinet 410 includes cabinet door 2211 and cabinet door 2212. Cabinet door 2211 and cabinet door 2212 are arranged opposite each other along the X direction.

[0185] Option 7

[0186] In “Scheme 7”, the charging host mentioned in “Scheme 1”, “Scheme 2”, “Scheme 3”, “Scheme 4”, “Scheme 5” or “Scheme 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 sequentially and spaced apart from the first and second receiving cavities along the X direction, 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, and the fourth receiving cavity 2310, along with the first receiving cavity 4101, the second receiving cavity 4102, and the third receiving cavity 1710, are arranged sequentially along the X direction and spaced apart. The charging host 40 also includes a charging connection module 2320, which is located within the fourth receiving cavity 2310. Thus, the charging connection module 2320, the liquid cooling 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 connection module can connect the charging host to at least one charging terminal to form an integrated charging device that combines the charging host and the charging terminal.

[0190] Optionally, the charging connection module can be 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 board.

[0192] Optionally, the charging device also includes a screen; the screen is mounted on the first outer surface of the cabinet, with the first outer surface facing the X direction. This allows the user to view the relevant power parameters of the charging device through the screen.

[0193] For example, as shown in Figure 24, based on Figure 23, the charging device also includes a screen 2410.

[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 surface of the cabinet, with the first outer surface facing the X direction. Thus, at least one charging gun can be used to connect to and charge an electric vehicle.

[0195] For example, as shown in Figure 25, based on Figure 23, the charging device also includes at least one charging gun 2510.

[0196] The specific embodiments described above further illustrate the purpose, technical solution, and beneficial effects of this application. It should be understood that the above description is only a specific embodiment of this application and is not intended to limit the scope of protection of this application.
