Description

Technical Field

[0001] The present application relates to the field of energy technology, and in particular to a charging device. Background Art

[0002] With the rapid development of the new energy vehicle industry, the charging power of electric vehicles has gradually increased, and the charging needs have become more diverse. In order to meet the charging needs of different vehicles and improve power utilization, modular charging hosts have received attention and development.

[0003] At present, most modular charging hosts adopt a structure in which modules are stacked vertically and an air-to-liquid heat exchanger is placed on top. That is, the modules in the charging host are stacked vertically and the air-to-liquid heat exchanger is placed on top of the charging host. However, the more modules are stacked vertically in this structure, the higher the overall height of the modular charging host will be, so the modular charging host cannot be placed in places with height restrictions. Utility Model Content

[0004] In the first aspect, a charging device of the present application includes a charging host, and the charging host includes a cabinet, a plurality of power conversion modules, and a plurality of power distribution modules. The cabinet includes a first receiving chamber and a second receiving chamber, and the first receiving chamber and the second receiving chamber are arranged in sequence and spaced apart along a first direction; the plurality of power conversion modules are used to convert input alternating current into direct current; the plurality of power distribution modules are used to distribute power to the direct current output by the plurality of power conversion modules; the plurality of power conversion modules are stacked in the first receiving chamber along a second direction, and the first direction is different from the second direction; the plurality of power distribution modules are stacked in the second receiving chamber along the second direction.

[0005] 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.

[0006] Optionally, the first direction is a longitudinal or vertical direction, and the second direction is a transverse or horizontal direction. In this way, the present embodiment can change the stacking direction of the multiple power conversion modules and the multiple power distribution modules in the charging host from the original longitudinal stacking to the transverse stacking. In other words, the multiple power conversion modules and the multiple power distribution modules are stacked along the vertical direction, and are stacked along the horizontal direction. In this way, by changing the stacking direction of the multiple power conversion modules and the multiple power distribution modules, the height of the charging host can be avoided as much as possible.

[0007] 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 multiple power conversion modules and multiple power distribution modules to the X direction, the height of the charging host can be avoided as much as possible.

[0008] 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.

[0009] In this way, the present application flexibly sets whether to stack multiple power conversion modules or multiple power distribution modules in a single row or multiple rows according to the needs in the receiving cavity of the cabinet. Among them, when multiple power conversion modules or multiple power distribution modules are stacked in a single row, this embodiment can realize simple and fast 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 places more power conversion modules or power distribution modules in a limited cabinet to improve space utilization.

[0010] Optionally, multiple power conversion modules include multiple AC rectifier modules and multiple DC voltage regulation modules; the multiple AC rectifier modules are used to convert the AC power input into the charging host into DC power; the multiple DC voltage regulation 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 regulation modules are stacked along the second direction in the first receiving cavity.

[0011] 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.

[0012] Optionally, a portion of the multiple 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.

[0013] 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.

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

[0015] 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.

[0016] Optionally, multiple AC rectifier modules are connected via an AC busbar, and the AC busbar is used to transmit AC power.

[0017] In this way, the AC busbar can be used to input AC power to multiple AC rectifier modules and transmit AC power between multiple AC rectifier modules.

[0018] Optionally, the AC busbar has a light stacking function. Wherein, the AC busbar has a light stacking function, and it can be understood that the AC busbar can transmit the AC power output by the photovoltaic power generation system.

[0019] It can be seen that the charging device of this embodiment can be connected to the 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 the electric vehicle.

[0020] Optionally, the multiple AC rectifier modules and the multiple DC voltage regulator modules are connected via a DC busbar, and the DC busbar is used to transmit DC power.

[0021] In this way, the DC busbar can be used to transmit the DC power output by the multiple AC rectifier modules to the multiple DC voltage regulator modules, and the DC power can be transmitted between the multiple DC voltage regulator modules.

[0022] Optionally, the DC busbar has a stacking storage function. Wherein, the DC busbar has a stacking storage function, and it can be understood that the DC busbar can transmit the DC power output by the energy storage device. Wherein, the energy storage device is a device that can store DC power.

[0023] It can be seen that the charging device of this embodiment can be connected to the energy storage device, and the DC voltage regulator module can be used to regulate the voltage of the DC power output by the energy storage device. In this way, the charging device of this embodiment can use the DC power of the energy storage device to charge the electric vehicle.

[0024] Optionally, a part of the multiple AC rectifier modules are connected to a part of the DC voltage regulation modules in the multiple DC voltage regulation modules through a first DC busbar, and the remaining AC rectifier modules in the multiple AC rectifier modules are connected to the remaining DC voltage regulation modules in the multiple DC voltage regulation modules 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.

[0025] It can be seen that in this embodiment, a part of the AC rectifier modules and a part of the DC voltage regulator modules can be connected through the first DC busbar, and the remaining AC rectifier modules and the remaining DC voltage regulator modules can be connected through 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 line of one of the DC busbars without adjusting the line of another DC busbar, thereby reducing the amount of DC busbar line adjustment.

[0026] Optionally, the first DC busbar and / or the second DC busbar has a stacking storage function.

[0027] It can be seen that the charging device of this embodiment can be connected to the energy storage device, and the DC voltage regulator module can be used to regulate the voltage of the DC power output by the energy storage device. In this way, the charging device of this embodiment can use the DC power of the energy storage device to charge the electric vehicle.

[0028] Optionally, multiple DC voltage regulation modules are directly plugged into multiple power distribution modules.

[0029] In this way, by directly plugging in, the transmission loss of DC power between multiple DC voltage regulator modules and multiple power distribution modules can be reduced, while the line layout between multiple DC voltage regulator modules and multiple power distribution modules can be reduced, reducing line materials and improving space utilization.

[0030] Optionally, a ratio of the number of AC rectifier modules of the multiple AC rectifier modules to the number of DC voltage regulator modules of the multiple DC voltage regulator modules is inversely proportional to a ratio of the power of the multiple AC rectifier modules to the power of the multiple DC voltage regulator modules.

[0031] It can be seen that 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 module can be equal to the number of DC voltage regulator modules multiplied by the power of the DC voltage regulator module.

[0032] 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.

[0034] 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.

[0035] 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, thereby reducing the adjustment workload and time.

[0036] Optionally, the multiple power distribution modules are integrally located on one side of the AC input module.

[0073] In order to better understand the technical solution of the present application, the technical solution of the present application is clearly and completely described below in conjunction with the drawings in the present application. Obviously, the described embodiments are only some embodiments of the present application, but not all embodiments. Based on the description of the embodiments of the present application, all other embodiments obtained by those skilled in the art without making creative work are within the scope of protection of the present application.

[0074] It should be understood that the terms "first", "second", etc., referred to in this application are used to distinguish different objects, rather than to describe a specific order. In addition, the terms "including" and "having" and any variations thereof are intended to cover non-exclusive inclusions. For example, a process, method, software, product, or device that includes a series of steps or units is not limited to the listed steps or units, but also includes steps or units that are not listed, or also includes other steps or units inherent to these processes, methods, products, or devices.

[0075] The "embodiment" referred to in this application means that the specific features, structures or characteristics described in conjunction with the embodiment may be included in at least one embodiment of the present application. The appearance of this phrase in various places in the specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment that is mutually exclusive with other embodiments. In addition, the embodiments described herein may be combined with other embodiments.

[0076] In the embodiments of the present application, "and / or" can describe the association relationship of the associated objects, and there can be three kinds of relationships. For example, A and / or B can represent the following three situations: "A", "B", "A and B". Among them, A and B can be singular or plural.

[0077] The symbol " / " in the embodiments of the present application can indicate that the objects associated with each other are in an "or" relationship. In addition, the symbol " / " can also indicate a division sign, that is, performing a division operation. For example, A / B can indicate A divided by B.

[0078] "At least one item" or similar expressions in the embodiments of the present application refers to any combination of these items, including any combination of single items or plural items, and refers to one or more, and "plurality" 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.

[0079] The "coupling" and "connection" in the embodiments of the present application can be used to indicate electrical connection, which can include direct connection through wires or connection terminals or indirect connection through other devices (such as inductors, capacitors or resistors, etc.). Therefore, "coupling" and "connection" can be regarded as a broad electronic communication connection. In addition, the mutual coupling / direct coupling / connection shown or discussed can be indirect coupling, connection through some interfaces, devices, units or devices, which can be in the form of communication, electrical or other.

[0080] Each circuit or other component in the embodiments of the present application may be described as "used to" perform one or more tasks. In this case, "used to" may imply a structure by indicating that the circuit / component includes a structure (e.g., a circuit system) that performs one or more tasks during operation. Therefore, even when a specified circuit / component is currently inoperable, the circuit / component may be referred to as being used to perform the task. Circuits / components used with the wording "used to" include hardware, such as circuits that perform operations, etc.

[0081] A charging device is a device that converts AC power into DC power and provides charging needs for electric vehicles.

[0082] 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.

[0083] The charging host refers to a device that converts AC power into DC power, regulates the voltage of DC power, and then distributes the regulated DC power, that is, a power conversion and power distribution device. It usually includes components such as rectifiers, filters, transformers, and inverters.

[0084] Charging terminal refers to a device that receives the DC power output by the charging host and connects and charges the electric vehicle. It usually includes a socket, a connecting wire and related control circuits. The user can insert the charging plug of the electric vehicle into the socket of the charging terminal and connect the charging terminal to the electric vehicle through the connecting wire.

[0085] The following is an example of a charging scenario provided by the charging device. Figure 1is a schematic diagram of a charging scenario of this embodiment. Figure 1 In the embodiment, 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. The charging device 110 can convert the AC power in the power grid 130 into DC power, and distribute the DC power to the electric vehicle 120 after voltage regulation, so as to charge the electric vehicle 120. The electric energy in the power grid 130 can be industrial electricity, or civil electricity, etc.

[0086] The functions of the charging device can be modularized. That is, the charging device is divided into different functional modules according to its functions, and the interface form between different functional modules is fixed or has an evolutionary relationship with the corresponding power. In this way, this embodiment can combine different functions according to different functional modules, and the capacity of the charging device can be adjusted by increasing or decreasing the number of functional modules.

[0087] For example, for the modularization of the power conversion function of the charging device, the present embodiment may introduce a power conversion module. Among them, the power conversion module may be used to convert alternating current into direct current and to regulate the voltage of the direct current. The power conversion module may be referred to as a power module. In addition, the number of power conversion modules may be multiple, and the number of power conversion modules may be continuously adjusted as needed, so as 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.

[0088] For another example, for the modularization of the power distribution function of the charging device, the present embodiment may introduce a power distribution module. Among them, the power distribution module may be used to distribute the DC power regulated by the power conversion module to the charging terminal. The power distribution module may be called a power matrix. In addition, the number of power distribution modules may be multiple, and the number of power distribution modules may be continuously adjusted as needed, so as 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.

[0089] The modularization of the charging device is described below with examples. Figure 2 Schematic diagram of a functional module of a charging device of this embodiment. Figure 2In the embodiment, the charging device 20 includes a charging host 210 and a charging terminal 220. The charging host 210 includes a plurality of power conversion modules (such as a power conversion module 2111, a power conversion module 2112, a power conversion module 2113, and a power conversion module 2114) and a plurality of power distribution modules (such as a power distribution module 2121, a power distribution module 2122, and a power distribution module 2123).

[0090] At present, most modules in modular charging hosts adopt a structure in which the modules are stacked vertically and the air-to-liquid heat exchanger is placed on the top. That is, the modules in the charging host are stacked vertically and the air-to-liquid heat exchanger is placed on the top of the charging host. However, the more modules are stacked vertically in this structure, the higher the overall height of the modular charging host will be, so the modular charging host cannot be placed in a place with height restrictions.

[0091] For example, taking the vertical direction as the Z direction in the three-dimensional coordinate system, Figure 3 FIG. 1 is a schematic diagram of a modular charging host in this embodiment, in which modules are stacked vertically. Figure 3 In the embodiment, the charging host 30 includes a cabinet 310, a plurality of 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, etc.) and an air-to-liquid heat exchanger 330. The plurality of power conversion modules are stacked from bottom to top along the Z direction, and the air-to-liquid heat exchanger 330 is placed on the top of the cabinet 310. In this way, in the face of high-power scenarios, the number of power conversion modules required for this architecture will be more, and the more power conversion modules will result in a higher overall height of the charging host 30, so that the charging host 30 cannot be arranged in a place with height restrictions.

[0092] Since the modular charging host adopts the structure of vertically stacking modules and the top-mounted air-to-liquid heat exchanger cannot be applied to places with height restrictions, the present 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.

[0093] In the following embodiment, the "modular charging host" is referred to as the "charging host", and the following multiple schemes are used to illustrate how to optimize the direction of module stacking. The same contents between different schemes can be referenced to each other, which will not be repeated here.

[0094] [Solution 1]

[0095] In "Solution 1", this embodiment can change the stacking direction of multiple power conversion modules and multiple power distribution modules in the charging host from the original longitudinal stacking to the transverse stacking. In other words, the multiple power conversion modules and multiple power distribution modules are stacked in the horizontal direction instead of the original vertical direction. In this way, by changing the stacking direction of the multiple power conversion modules and the multiple power distribution modules, the height of the modular charging host can be avoided as much as possible.

[0096] 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.

[0097] In "Scheme 1", this embodiment can divide the receiving cavity of the cabinet of the charging host into two upper and lower receiving cavities along the Z direction (for the convenience 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 place multiple power distribution modules in the second receiving cavity. Among them, 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 (for the convenience of description, the "X direction" here can be referred to as the "second direction").

[0098] For example, Figure 4 Schematic diagram of the structure of a charging host in this embodiment. Figure 4 In the embodiment, the charging host 40 includes a cabinet 410, a plurality of 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, etc.) and a plurality of 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. The plurality of power conversion modules 420 are stacked along the X direction in the first receiving cavity 4101, and the plurality of power distribution modules 430 are stacked along the X direction in the second receiving cavity 4102.

[0099] 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.

[0100] In this way, the present embodiment flexibly sets whether to stack multiple power conversion modules or multiple power distribution modules in a single row or multiple rows according to the needs in the receiving cavity of the cabinet. Among them, when multiple power conversion modules or multiple power distribution modules are stacked in a single row, the present embodiment can realize simple and fast 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, the present embodiment places more power conversion modules or power distribution modules in a limited cabinet, thereby improving space utilization.

[0101] For example, in Figure 4 In the embodiment, a plurality of power conversion modules 420 are stacked in a single row along the X direction in the first receiving cavity 4101 , and a plurality of power distribution modules 430 are stacked in a single row along the X direction in the second receiving cavity 4102 .

[0102] For example, Figure 5 1 is a schematic diagram of the structure of a charging host in this embodiment viewed from above along the Z axis. Figure 5 In the embodiment, the charging host 50 includes a cabinet 510 and a plurality of power conversion modules 520 (such as 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 plurality of power conversion modules 520 are stacked in a single row along the X direction in the first receiving cavity 4101 of the cabinet 510.

[0103] For example, Figure 6 FIG. 1 is a schematic diagram of another charging host in this embodiment viewed from above along the Z axis. Figure 6 In the embodiment, the charging host 60 includes a cabinet 610 and a plurality of 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 plurality of power conversion modules 620 are stacked in two rows along the X direction in 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.

[0104] [Solution 2]

[0105] In "Solution 2", this embodiment can change the stacking direction of multiple power conversion modules and multiple power distribution modules in the charging host from the original longitudinal stacking to the transverse stacking. In other words, the multiple power conversion modules and multiple power distribution modules are stacked in the horizontal direction instead of the original vertical direction. In this way, by changing the stacking direction of the multiple power conversion modules and the multiple power distribution modules, the height of the modular charging host can be avoided as much as possible.

[0106] 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.

[0107] In "Scheme 2", this embodiment can divide the receiving cavity of the cabinet of the charging host into two front and rear receiving cavities along the Y direction (for the convenience of description, the "Y direction" here can be referred to as the "first direction"), and then place multiple power conversion modules in the first receiving cavity, and place multiple power distribution modules in the second receiving cavity. Among them, 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 (for the convenience of description, the "X direction" here can be referred to as the "second direction").

[0108] For example, Figure 7 FIG. 1 is a schematic diagram of the structure of another charging host in this embodiment. Figure 7 In the embodiment, the charging host 70 includes a cabinet 710, a plurality of 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, etc.) and a plurality of 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. The plurality of power conversion modules 720 are stacked along the X direction in the first receiving cavity 7101, and the plurality of power distribution modules 730 are stacked along the X direction in the second receiving cavity 7102.

[0109] 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.

[0110] In this way, the present embodiment flexibly sets whether to stack multiple power conversion modules or multiple power distribution modules in a single row or multiple rows according to the needs in the receiving cavity of the cabinet. Among them, when multiple power conversion modules or multiple power distribution modules are stacked in a single row, the present embodiment can realize simple and fast 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, the present embodiment places more power conversion modules or power distribution modules in a limited cabinet, thereby improving space utilization.

[0111] [Solution 3]

[0112] "Scheme 3" further explains the multiple power conversion modules and multiple power distribution modules mentioned in the above "Scheme 1" or "Scheme 2".

[0113] 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 the multiple DC voltage regulator modules are stacked along the X direction in the first receiving cavity.

[0114] A plurality of AC rectifier modules can be used to convert the AC power input into the charging host into DC power. The AC rectifier module can include an alternating current / direct current (AC / DC) converter.

[0115] 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.

[0116] 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.

[0117] Optionally, a portion of the multiple 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.

[0118] For example, Figure 8 Schematic diagram of the structure of a charging host along the Y axis of this embodiment. Figure 8In the embodiment, the charging host 80 includes a cabinet 810, a plurality of 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 a plurality of 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, etc.). 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. The multiple AC rectifier modules 820 and the multiple DC voltage regulator modules 830 are stacked along the X direction in 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.

[0119] 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.

[0120] 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.

[0121] For example, Fig. 9 1 is a schematic diagram of the structure of another charging host along the Y axis of this embodiment. Fig. 9In the embodiment, the charging host 90 includes a cabinet 910, a plurality of 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 a plurality of 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 receiving cavity of the cabinet 910 is divided into a first receiving cavity 9101 and a second receiving cavity 9102 along the Z direction. The multiple AC rectifier modules 920 and the multiple DC voltage regulator modules 930 are stacked in the first receiving cavity 9101 along the X direction. The multiple DC voltage regulator modules 930 are located on one side of the multiple AC rectifier modules 920 as a whole.

[0122] 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.

[0123] Optionally, multiple AC rectifier modules are connected via an AC busbar, which is used to transmit AC power. The AC busbar may be a conductive material used to transmit and distribute AC power, and may be made of copper or aluminum, and may have a flat or long shape.

[0124] In this way, the AC busbar can be used to input AC power to multiple AC rectifier modules and transmit AC power between multiple AC rectifier modules.

[0125] For example, Fig.10 As shown, in Figure 8 On the basis of, multiple AC rectifier modules 820 are connected through an AC busbar 1010.

[0126] Optionally, the AC busbar has a light stacking function. Wherein, the AC busbar has a light stacking function, and it can be understood that the AC busbar can transmit the AC power output by the photovoltaic power generation system.

[0127] It can be seen that the charging device of this embodiment can be connected to the 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 the electric vehicle.

[0128] 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 may be a conductive material used to transmit and distribute DC power, and may be made of copper or aluminum, and may have a flat or long shape.

[0129] For example, Fig.11 As shown, in Fig. 9 On the basis of, multiple AC rectifier modules 920 and multiple DC voltage regulation modules are connected through an AC busbar 1110.

[0130] In this way, the DC busbar can be used to transmit the DC power output by the multiple AC rectifier modules to the multiple DC voltage regulator modules, and the DC power can be transmitted between the multiple DC voltage regulator modules.

[0131] Optionally, the DC busbar has a stacking storage function. Wherein, the DC busbar has a stacking storage function, and it can be understood that the DC busbar can transmit the DC power output by the energy storage device. Wherein, the energy storage device is a device that can store DC power.

[0132] It can be seen that the charging device of this embodiment can be connected to the energy storage device, and the DC voltage regulator module can be used to regulate the voltage of the DC power output by the energy storage device. In this way, the charging device of this embodiment can use the DC power of the energy storage device to charge the electric vehicle.

[0133] Optionally, a part of the multiple AC rectifier modules are connected to a part of the DC voltage regulation modules in the multiple DC voltage regulation modules through a first DC busbar, and the remaining AC rectifier modules in the multiple AC rectifier modules are connected to the remaining DC voltage regulation modules in the multiple DC voltage regulation modules 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.

[0134] For example, Fig.12 As shown, in Figure 8 On the basis of this, a part of the AC rectifier modules in 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 the first DC bus 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 the second DC bus 1220.

[0135] It can be seen that in this embodiment, a part of the AC rectifier modules and a part of the DC voltage regulator modules can be connected through the first DC busbar, and the remaining AC rectifier modules and the remaining DC voltage regulator modules can be connected through 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 line of one of the DC busbars without adjusting the line of another DC busbar, thereby reducing the amount of DC busbar line adjustment.

[0136] Optionally, the first DC busbar and / or the second DC busbar has a stacking storage function.

[0137] It can be seen that the charging device of this embodiment can be connected to the energy storage device, and the DC voltage regulator module can be used to regulate the voltage of the DC power output by the energy storage device. In this way, the charging device of this embodiment can use the DC power of the energy storage device to charge the electric vehicle.

[0138] Optionally, multiple DC voltage regulation modules are directly plugged into multiple power distribution modules.

[0139] In this way, by directly plugging in, the transmission loss of DC power between multiple DC voltage regulator modules and multiple power distribution modules can be reduced, while the line layout between multiple DC voltage regulator modules and multiple power distribution modules can be reduced, reducing line materials and improving space utilization.

[0140] For example, Fig.13 As shown, in Figure 8 On the basis of this, 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; the DC voltage regulation module 8311 and the DC voltage regulation module 8312 are directly plugged into the power distribution module 13106.

[0141] For example, Fig.14 As shown, in Fig. 9On the basis of this, 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; the DC voltage regulation module 9311 and the DC voltage regulation module 9312 are directly plugged into the power distribution module 14106.

[0142] Optionally, a ratio of the number of AC rectifier modules of the multiple AC rectifier modules to the number of DC voltage regulator modules of the multiple DC voltage regulator modules is inversely proportional to a ratio of the power of the multiple AC rectifier modules to the power of the multiple DC voltage regulator modules.

[0143] It can be seen that 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 module can be equal to the number of DC voltage regulator modules multiplied by the power of the DC voltage regulator module.

[0144] [Solution 4]

[0145] 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.

[0146] In this way, the AC input module can realize input of AC power from the outside to the charging host and transmit the AC power to the power conversion module for processing.

[0147] 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.

[0148] For example, Fig.15 As shown, in Fig.13 On the basis of the AC input module 1510, the charging host 80 further includes an AC input module 1510. The AC input module 1510 and the plurality of power distribution modules 1310 are stacked along the X direction in the second receiving cavity 8102. Part of the plurality of 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.

[0149] 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, thereby reducing the adjustment workload and time.

[0150] Optionally, the plurality of power distribution modules are integrally located on one side of the AC input module, that is, all the power distribution modules are stacked on top of each other.

[0151] For example, Fig.16 As shown, in Fig.14 On the basis of the charging host 90, 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 in the second receiving cavity 9102. Among them, the multiple power distribution modules 1410 are located on one side of the AC input module 1610 as a whole.

[0152] 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.

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

[0155] For example, the liquid cooling module includes components such as a water pump, a heat exchanger, a fan, a kettle, a pipe, 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.

[0156] 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.

[0157] Method 1

[0158] The cabinet housing in "Scheme 1" is divided into an upper and lower first housing cavity and a second housing cavity along the Z direction, and multiple power conversion modules are stacked in the first housing cavity along the X direction, and multiple power distribution modules are stacked in the second housing cavity along the X direction. Therefore, in "Method 1", the third housing cavity can be arranged in sequence with the first housing cavity and the second housing cavity along the X direction and spaced apart.

[0159] In this way, since the liquid cooling and heat dissipation module is in the third receiving cavity, the liquid cooling and heat dissipation module, the multiple power conversion modules and the multiple power distribution modules are all arranged along the X direction to avoid the height of the modular charging host being too high.

[0160] Optionally, the third receiving cavity is on one side or both sides of the first receiving cavity and the second receiving cavity.

[0161] For example, taking the third receiving chamber on one side of the first receiving chamber and the second receiving chamber as an example, Fig.17 As shown, in Figure 4 On the basis of the above, the cabinet 410 further includes a third receiving cavity 1710, and the third receiving cavity 1710 is sequentially arranged and spaced apart with the first receiving cavity 4101 and the second receiving cavity 4102 along the X direction. The charging host 40 further includes a liquid cooling and heat dissipation module 1720, and the liquid cooling and heat dissipation module 1720 is in the third receiving cavity 1710. In this way, 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.

[0162] For another example, taking the third receiving cavity on both sides of the first receiving cavity and the second receiving cavity as an example, Fig.18 As shown, in Figure 4 On the basis of the above, the cabinet 410 further includes a third receiving cavity 1810, and the third receiving cavity 1810 and the first receiving cavity 4101 and the second receiving cavity 4102 are arranged in sequence and spaced along the X direction, and the third receiving cavity 1810 is on both sides of the first receiving cavity 4101 and the second receiving cavity 4102. The charging host 40 further includes a liquid cooling and heat dissipation module 1820, and the liquid cooling and heat dissipation module 1820 is in the third receiving cavity 1810. In this way, 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.

[0163] Method 2

[0164] The receiving cavity of the cabinet 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.

[0165] In this way, since the liquid cooling heat dissipation module is in the third receiving chamber, the liquid cooling heat dissipation module can be arranged on the top of the charging host. In addition, the liquid cooling heat dissipation module is arranged on the top of the charging host to improve the heat dissipation efficiency and reduce the noise generated by the liquid cooling heat dissipation module.

[0166] Optionally, the third receiving cavity is on one side or both sides of the first receiving cavity and the second receiving cavity.

The charging host 40 further includes a liquid cooling and heat dissipation module 1920, and the liquid cooling and heat dissipation module 1920 is in the third receiving cavity 1910. In this way, the liquid cooling and heat dissipation module 1920 is arranged on the top of the charging host 40.

[0168] Method 3

[0169] The cabinet housing cavity in "Scheme 2" is divided into a front and rear first housing cavity and a second housing cavity along the Y direction, and multiple power conversion modules are stacked in the first housing cavity along the X direction, and multiple power distribution modules are stacked in the second housing cavity along the X direction. Therefore, in "Method 3", the third housing cavity can be arranged in sequence with the first housing cavity and the second housing cavity along the X direction and spaced apart.

[0170] In this way, since the liquid cooling and heat dissipation module is in the third receiving cavity, the liquid cooling and heat dissipation module, the multiple power conversion modules and the multiple power distribution modules are all arranged along the X direction to avoid the height of the modular charging host being too high.

[0171] Optionally, the third receiving cavity is on one side or both sides of the first receiving cavity and the second receiving cavity.

[0172] For example, taking the third receiving chamber on one side of the first receiving chamber and the second receiving chamber as an example, Fig. 20 As shown, in Figure 7On the basis of the above, the cabinet 710 further includes a third receiving cavity 2010, and the third receiving cavity 2010 is sequentially arranged and spaced with the first receiving cavity 7101 and the second receiving cavity 7102 along the X direction. The charging host 70 further includes a liquid cooling and heat dissipation module 2020, and the liquid cooling and heat dissipation module 2020 is in the third receiving cavity 2010. In this way, 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.

[0173] Method 4

[0174] The receiving cavity of the cabinet 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.

[0175] In this way, since the liquid cooling heat dissipation module is in the third receiving chamber, the liquid cooling heat dissipation module can be arranged on the top of the charging host. In addition, the liquid cooling heat dissipation module is arranged on the top of the charging host to improve the heat dissipation efficiency and reduce the noise generated by the liquid cooling heat dissipation module.

[0176] Optionally, the third receiving cavity is on one side or both sides of the first receiving cavity and the second receiving cavity.

[0177] [Solution 6]

[0178] In "Solution 6", the cabinet of the charging host mentioned in "Solution 1", "Solution 2", "Solution 3", "Solution 4" or "Solution 5" may include a plurality of cabinet doors. In this way, the internal space of the cabinet can be opened through the plurality of cabinet doors, so as to facilitate the arrangement of the modules in the cabinet.

[0179] It should be noted that the multiple cabinet doors can be opened by stretching outward, or by sliding the cabinet doors up and down, or by sliding the cabinet doors left and right, etc. In addition, the multiple cabinet doors can be retractable, or non-retractable, etc.

[0180] Optionally, the plurality of cabinet doors may 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 so as to view the modules stacked along the X direction.

The charging host 40 further includes a charging connection module 2320, and the charging connection module 2320 is in the fourth receiving cavity 2310. In this way, the charging connection module 2320, the liquid cooling module 1720, the multiple power conversion modules 420 and the multiple power distribution modules 430 are all arranged along the X direction.

[0187] 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.
