Technical Field

Detailed Implementation

[0062] The technical solutions of the embodiments 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 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.

Therefore, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this application, unless otherwise stated, "a plurality of" means two or more.

[0065] In the description of this application, it should be noted that, unless otherwise expressly specified and limited, the terms "installation," "connection," "linking," and "communication" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection.

[0068] In the description of this specification, specific features, structures, materials, or characteristics may be combined in any suitable manner in one or more embodiments or examples.

[0069] Embodiments of this disclosure provide a charging host 100, with reference to Figure 1 It includes: a housing 10, a conversion module 101 and a power distribution module 102. The conversion module 101 and the power distribution module 102 are located inside the housing 10 and are electrically connected. The power distribution module 102 and the conversion module 101 are used to connect the DC power supply module and the electrical load.

[0070] The DC power module can be located inside or outside the housing 10. The structural diagram of the charging host 100 provided in this disclosure illustrates the case where the DC power module is located outside the housing 10. Having the DC power module inside the housing 10 improves integration; having it outside facilitates repair and maintenance.

[0071] Electrical loads can be installed inside enclosure 10, which provides effective protection for them, reducing the risk of electric shock and ensuring the safety of personnel and equipment. Alternatively, electrical loads can be installed outside enclosure 10, facilitating testing and maintenance.

[0072] The charging host 100 provided in this embodiment can charge the electrical load via the DC power module because the conversion module 101 and the power distribution module 102 are electrically connected, and the power distribution module 102 and the conversion module 101 are used to connect the DC power module and the electrical load. In contrast, the charging host 100 can only charge the electrical load via the AC power module, thus solving the problem of the charging host having only one charging mode.

[0073] In some embodiments, continue to refer to Figure 1 The power distribution module 102 and the conversion module 101 are arranged adjacent to each other. This arrangement can reduce the distance between the power distribution module 102 and the conversion module 101, and shorten the length of the connector used to electrically connect the power distribution module 102 and the conversion module 101, thereby achieving the effect of saving costs.

[0074] In some embodiments, the conversion module 101 has an input section (not shown) and an output section (not shown) on one side, and the power distribution module 102 is located on the side of the conversion module 101 near the input section and the output section. In this way, the power distribution module 102 is close to the input section and the output section of the conversion module 101, which can shorten the length of the connector used to electrically connect the power distribution module 102 and the conversion module 101, thereby achieving the effect of saving costs.

[0075] In some embodiments, the conversion module 101 includes a DC-DC conversion module 11, and a power distribution module 102 is disposed on the side of the DC-DC conversion module 11 near the input and output sections. This proximity of the power distribution module 102 to the input and output sections of the DC-DC conversion module 11 shortens the length of the connectors used to electrically connect the power distribution module 102 and the DC-DC conversion module 11, thus saving costs.

[0076] The DC-DC converter module 11 can convert the fixed DC voltage output by the DC power module into a variable DC voltage. It can convert the input DC voltage into a specific voltage suitable for charging the host, and can also provide a stable DC power supply to the host through precise voltage regulation, which helps to ensure efficient charging.

[0077] In some embodiments, the power distribution module 102 and the conversion module 101 are also used to connect the AC power module and the electrical load. The charging host 100 can supply power to the electrical load not only using an AC power module but also using a DC power module, increasing the charging modes of the charging host. Furthermore, it can simultaneously supply power to the electrical load using both AC and DC power modules, thus increasing the output power of the charging host 100. Therefore, the charging host 100 provided in this application has a high total power.

[0078] In some embodiments, continue to refer to Figure 1 The charging host 100 also includes an AC input module 104, which is located inside the housing 10; the housing 10 is provided with a housing door, and the AC input module 104 is arranged adjacent to the housing door.

[0079] The AC input module 104 is used to receive and process AC power input from the power grid, such as three-phase AC power from the power grid. It is the interface between the charging host 100 and the external power grid, responsible for introducing AC power from the power grid into the charging host 100 and performing preliminary preprocessing and protection. The AC input module 104 can disconnect the input of three-phase AC power in an emergency.

[0080] The AC input module 104 is positioned adjacent to the enclosure door, which facilitates the connection between the AC input module 104 and the external power grid. The external power grid can be considered as the AC power module described above.

[0081] In some embodiments, continue to refer to Figure 1 The charging host 100 also includes a power conversion module 105, which is located inside the housing 10; the power conversion module 105 is located on the side of the AC input module 104 away from the housing door.

[0082] The power conversion module 105 is used to output the DC power from the conversion module 101 to the electrical load, for example, to output the DC power from the DC-DC conversion module 11 to the electrical load. Based on the charging state and charging strategy of the electrical load, the output power (including voltage and current) is dynamically adjusted to ensure that the battery of the electrical load can be charged safely and efficiently. Therefore, placing the power conversion module 105 on the side of the AC input module 104 away from the enclosure door can shorten the distance between the power conversion module 105 and the electrical load, and shorten the length of the connectors used to electrically connect the power conversion module 105 and the electrical load, thus achieving cost savings.

[0083] Continue to refer to Figure 1 The charging host 100 also includes a heat dissipation module 106, which is located on the top of the charging host 100. The heat dissipation module 106 helps to dissipate the heat generated by the charging host 100 during operation in a timely manner, which can avoid the risk of fire caused by the overheating of the charging host 100.

[0084] The heat dissipation module 106 includes a heat sink 108. The heat dissipation module 106 can draw in air from both sides or all around, which can prevent the generated air from blowing directly onto the user and provide a better user experience.

[0085] For example, heat sink 108 includes a cooling fan.

[0086] In some embodiments, the charging host 100 further includes a fire-fighting device (not shown), disposed within the housing 10. During operation, the charging host 100 may experience fires due to prolonged operation, fluctuations in current and voltage, and changes in environmental factors. Fire-fighting devices (such as fire detection systems, alarm systems, and fire extinguishing systems) can monitor and warn of fire risks in real time, thereby effectively preventing fires. Fire-fighting devices can respond quickly to fires and initiate fire-fighting measures, thus ensuring personnel safety.

[0087] In some embodiments, continue to refer to Figure 1 The charging host 100 also includes a control module 107; the control module 107 is connected to the AC input module 104, the conversion module 101 and the power conversion module 105, and is arranged adjacent to at least one of the AC input module 104, the conversion module 101 and the power conversion module 105.

[0088] For example, such as Figure 1 As shown, the control module 107 is located on the side of the power conversion module 105 away from the bottom plate P of the enclosure 10.

[0089] The conversion module 101 may include an AC-DC conversion module 12 and a DC-DC conversion module 11. In this case, the control module 107 is connected to the AC-DC conversion module 12 and the DC-DC conversion module 11, respectively.

[0090] The control module 107 can adjust charging parameters (such as charging voltage, charging current, charging time, etc.) in real time, control the input and output of the power supply, and power conversion to optimize the charging effect of the charging host 100.

[0091] When designing the layout within the housing 10 of the charging host 100, the positions of the AC input module 104, conversion module 101, power conversion module 105, and control module 107 are flexible and can be adjusted arbitrarily. While ensuring the current path is as short as possible, the AC input module 104 must be placed adjacent to the conversion module 101. The AC-DC conversion module 12 and DC-DC conversion module 11 within the conversion module 101 are placed adjacent to each other, and the power conversion module 105 can be placed adjacent to the DC-DC conversion module 11. There are no strict restrictions on the specific arrangement of these modules. Possible arrangements can be found by referring to... Figure 2 , Figure 3 , Figure 4 and Figure 5 Of course, there are other possible arrangements.

[0092] For example, AC input module 104 and AC-DC converter module 12 are arranged adjacent to each other; AC-DC converter module 12 and DC-DC converter module 11 are arranged adjacent to each other; DC-DC converter module 11 and power distribution module 102 are arranged adjacent to each other; DC-DC converter module 11 and power conversion module 105 are arranged adjacent to each other. This arrangement can reduce the distance between adjacent modules and shorten the length of the cables used to connect adjacent modules, thereby saving costs.

[0093] When the DC power module is located inside the housing 10, the DC power module can be arranged adjacent to the conversion module 101, specifically adjacent to the DC-DC conversion module 11.

[0094] In some embodiments, reference Figure 1 The DC-DC converter module 11 includes multiple DC-DC converter sub-modules, which are independent units. When one DC-DC converter sub-module fails, the others can still operate normally, thus ensuring the stability and reliability of the charging host 100. In practical applications, the number of DC-DC converter sub-modules can be increased or decreased according to the required output power of the charging host 100, thereby increasing or decreasing the total output power of the charging host 100 accordingly.

[0095] In some embodiments, reference Figure 1 The AC-DC converter module 12 includes multiple AC-DC converter sub-modules. These multiple sub-modules allow the charging host 100 to handle more charging tasks simultaneously or provide higher charging power to the charging terminal, thus significantly shortening charging time and improving charging efficiency. Therefore, the number of AC-DC converter sub-modules can be increased or decreased according to the charging task or the charging power required by the charging terminal.

[0096] In some embodiments, in conjunction with reference Figure 7 and Figure 8 The conversion module 101 includes a DC-DC conversion module 11; the DC-DC conversion module 11 and the power distribution module 102 are electrically connected, and the DC-DC conversion module 11 and the power distribution module 102 are used to connect the DC power supply module 103 and the electrical load.

[0097] Specifically, the power distribution module 102 electrically connects the DC power supply module 103 to the DC-DC converter module 11. The DC-DC converter module 11 converts the fixed DC voltage output by the DC power supply module 103 into a variable DC voltage. Then, the DC-DC converter module 11 is electrically connected to the power conversion module 105. The power conversion module 105 outputs the DC power from the DC-DC converter module 11 to the electrical load.

[0098] The DC-DC converter module 11 (DCDC module) is used to further convert the input DC power into another type of DC power, typically to meet the voltage and current requirements of a specific load or battery charging. This conversion can include functions such as boost, buck, or regulation to ensure a stable and suitable power supply for the charging device.

[0099] For example, in conjunction with reference Figure 6 and Figure 7 The output terminal of the DC power module 103 is connected to the input terminal of the DC-DC converter module 11 via the power distribution module 102, enabling the DC power module 103 to supply power to the electrical load. In contrast, the charging host 100 can only charge the electrical load via the AC power module. The charging host 100 provided in this embodiment can solve the problem of the charging host having only one charging mode.

[0100] Figure 6 and Figure 7 In the charging host 100 shown, the DC power module 103 is located outside the housing 10. In other embodiments, the DC power module 103 may also be located inside the housing 10.

[0101] In some embodiments, reference Figure 7The power distribution module 102 includes at least one set of first connectors L1, which are configured to connect the output terminal of the DC power module 103 to the input terminal of the DC-DC converter module 11, so that the DC power module 103 can supply power to the electrical load. In this way, the charging host 100 does not need an external power grid and can supply power to the electrical load solely through the DC power module 103.

[0102] For example, refer to Figure 7 The power distribution module 102 includes a set of first connectors L1. In other embodiments, the power distribution module 102 may also include two sets of first connectors L1, three sets of first connectors L1, or four sets of first connectors L1. This embodiment does not limit this.

[0103] Multiple sets of first connectors L1 connect the output of the DC power module 103 to the input of the DC-DC converter module 11. This ensures electrical continuity even if one first connector L1 fails, while the others maintain electrical continuity, thus improving the reliability of the charging host 100. Furthermore, multiple sets of first connectors L1 help distribute the current load, reducing thermal and mechanical stress on individual first connectors L1, thereby extending the lifespan of both the first connectors L1 and the charging host 100. Additionally, different combinations of first connectors L1 can be selected to achieve different current or voltage specifications, or optimized for different operating conditions. When a first connector L1 fails, the charging host 100 using multiple sets of first connectors L1 allows for easier location and replacement of the faulty connector without requiring extensive disassembly or reconfiguration of the entire charging host 100. This helps reduce maintenance time and costs, and improves system availability.

[0104] In some embodiments, continue to refer to Figure 7 The DC-DC converter module 11 has two input terminals: a first input terminal (not shown) and a second input terminal (not shown). The DC power supply module 103 has two output terminals: a first output terminal (not shown) and a second output terminal (not shown). A set of first connectors L1 includes a first sub-connector L11 and a second sub-connector L12. The first sub-connector L11 has a first input port D1, and the second sub-connector L12 has a second input port D2. The first input port D1 is configured to connect to the first output terminal, and the second input port D2 is configured to connect to the second output terminal. The first sub-connector L11 is configured to connect the first output terminal to the first input terminal, and the second sub-connector L12 is configured to connect the second output terminal to the second input terminal. This allows for flexible control of connecting the DC power supply module 103 to the charging host 100 or disconnecting the DC power supply module 103 from the charging host 100.

[0105] In some embodiments, reference may be made to Figure 7 The conversion module 101 includes an AC-DC conversion module 12 and a DC-DC conversion module 11; the AC-DC conversion module 12 is electrically connected to the AC power supply module, and the DC-DC conversion module 11 is electrically connected to the power distribution module 102. The DC-DC conversion module 11 and the power distribution module 102 are used to connect an electrical load to the AC power supply module.

[0106] Specifically, refer to the following: Figure 7 and Figure 9 The AC power module outputs AC power to the AC input module 104. The AC input module 104 receives the AC power from the AC power module and performs preliminary processing and conversion to provide a stable and reliable AC power input for the subsequent charging process. Then, the AC input module 104 outputs the AC power to the AC-DC converter module 12. The AC-DC converter module 12 converts the AC power into DC power suitable for charging, and then outputs it through the power distribution module 102 to the DC-DC converter module 11. The DC-DC converter module 11 is electrically connected to the power conversion module 105, and the power conversion module 105 outputs the DC power from the DC-DC converter module 11 to the electrical load.

[0107] The main function of the AC-DC converter module 12 (ACDC module) is to convert the alternating current (AC) in the power grid into direct current (DC) suitable for charging. The AC-DC converter module 12 can not only adapt to different types of power supplies, enabling the charging host 100 to work normally in various power environments, but also helps to improve the efficiency of power use, reduce power waste, and protect the charging host 100 from voltage fluctuations and power instability through stable power output.

[0108] For example, the AC power module is electrically connected to the input terminal of the AC-DC converter module 12, and the output terminal of the AC-DC converter module 12 is connected to the input terminal of the DC-DC converter module 11 through the power distribution module 102, so that the AC power module can supply power to the electrical load.

[0109] Based on this, the power distribution module 102 includes at least one set of second connectors L2, which are configured to connect the output terminal of the AC-DC converter module 12 to the input terminal of the DC-DC converter module 11, so that the AC power module can supply power to the electrical load. In this way, the charging host 100 can supply power to the electrical load through the AC power module.

[0110] For example, refer to Figure 7 The power distribution module 102 includes a set of second connectors L2. In other embodiments, the power distribution module 102 may also include two sets of second connectors L2, three sets of second connectors L2, or four sets of second connectors L2. This embodiment does not limit this.

[0111] Multiple sets of second connectors L2 connect the output of the AC-DC converter module 12 to the input of the DC-DC converter module 11. This ensures electrical continuity even if one set of second connectors L2 fails, improving the reliability of the charging host 100. Furthermore, multiple sets of second connectors L2 help distribute the current load, reducing thermal and mechanical stress on individual connectors L2, thus extending the lifespan of both the connectors L2 and the charging host 100. Different combinations of second connectors L2 can be selected to achieve different current or voltage specifications, or optimized for different operating conditions. When a second connector L2 fails, the charging host 100 with multiple sets of second connectors L2 can more easily locate and replace the faulty connector without requiring large-scale disassembly or reconfiguration of the entire charging host 100. This helps reduce maintenance time and costs, and improves system availability.

[0112] The AC-DC converter module 12 has a third output terminal and a fourth output terminal, and the DC-DC converter module 11 has a first input terminal and a second input terminal. A set of second connectors L2 includes a third sub-connector L21 and a fourth sub-connector L22. The third sub-connector L21 is configured to connect the third output terminal and the first input terminal, and the fourth sub-connector L22 is configured to connect the fourth output terminal and the second input terminal.

[0113] In some other embodiments, the conversion module 101 includes an AC-DC conversion module 12 and a DC-DC conversion module 11; the AC-DC conversion module 12 is electrically connected to the AC power supply module, and the DC-DC conversion module 11 is electrically connected to the power distribution module 102. The DC-DC conversion module 11 and the power distribution module 102 are used to connect to the DC power supply module using an electrical load.

[0114] For example, the output terminal of the DC power module 103 is connected to the input terminal of the DC-DC converter module 11 through the power distribution module 102, so that the DC power module 103 can supply power to the electrical load.

[0115] In other embodiments, the conversion module 101 includes an AC-DC conversion module 12 and a DC-DC conversion module 11; the AC-DC conversion module 12 is electrically connected to the AC power module, and the DC-DC conversion module 11 is electrically connected to the power distribution module 102. The DC-DC conversion module 11 and the power distribution module 102 are used to connect to the AC power module and the DC power module using an electrical load.

[0116] For example, refer to Figure 10The power distribution module 102 electrically connects the DC power supply module 103 to the first set of DC-DC converter modules. The first set of DC-DC converter modules converts the fixed DC voltage output by the DC power supply module 103 into a variable DC voltage. The AC power supply module outputs AC power to the AC input module 104, which receives the AC power from the AC power supply module. Then, the AC input module 104 outputs the AC power to the AC-DC converter module 12, which converts the AC power into DC power suitable for charging. This DC power is then output through the power distribution module 102 to the second set of DC-DC converter modules. The first and second sets of DC-DC converter modules are electrically connected to the power conversion module 105, which then outputs the DC power from the two DC-DC converter modules 11 to the electrical load.

[0117] Each of the first and second DC-DC converter modules can include one or more DC-DC converter sub-modules. The specific number can be expanded according to actual needs.

[0118] For example, refer to Figure 11 The AC power module outputs AC power to the AC input module 104, which receives the AC power from the AC power module. Then, the AC input module 104 outputs the AC power to the AC-DC converter module 12. After that, the power distribution module 102 electrically connects the DC power module 103 to the AC-DC converter module 12, and inputs the DC power output from the DC power module 103 and the AC-DC converter module 12 together into the same DC-DC converter module 11. The DC-DC converter module 11 then outputs the DC power to the power conversion module 105, and the power conversion module 105 then outputs the DC power to the electrical load.

[0119] For example, refer to Figure 12 The AC power module outputs AC power to the AC input module 104, which receives the AC power from the AC power module. Then, the AC input module 104 outputs the AC power to the AC-DC converter module 12 to form DC power. The AC-DC converter module 12 then outputs the DC power to the DC-DC converter module 11. The DC power module 103 outputs the DC power to another DC-DC converter module 11. Then, the power distribution module 102 integrates the DC power output from these two DC-DC converter modules 11 and outputs it to the power conversion module 105. The power conversion module 105 then outputs the DC power to the electrical load.

[0120] exist Figure 10In the circuit shown, exemplarily, the AC power module is electrically connected to the input terminal of the AC-DC converter module 12, and the output terminal of the AC-DC converter module 12 is connected to the input terminal of the DC-DC converter module 11 via the power distribution module 102; and the output terminal of the DC power module 103 is connected to the input terminal of the DC-DC converter module 11 via the power distribution module 102, so that the AC power module and the DC power module 103 can simultaneously supply power to the electrical load. This increases the output power of the charging host 100.

[0121] Based on this, refer to Figure 7 The power distribution module 102 includes: at least one set of adapters L3, at least one set of first connectors L1, and at least one set of second connectors L2; ​​the at least one set of first connectors L1 is configured to connect the output terminal of the DC power supply module 103 to the input terminal of the DC-DC converter module 11; the at least one set of second connectors L2 is configured to connect the output terminal of the AC-DC converter module 12 to the input terminal of the DC-DC converter module 11; the at least one set of adapters L3 is configured to connect the at least one set of first connectors L1 to the at least one set of second connectors L2, so that the DC power supply module 103 and the AC power supply module can simultaneously supply power to the electrical load.

[0122] In this way, the charging host 100 can integrate the current from the AC power module and the DC power module 103, thereby improving the charging efficiency of the charging host 100.

[0123] For example, refer to Figure 7 The power distribution module 102 includes: a set of adapters L3, a set of first connectors L1, and a set of second connectors L2. In other embodiments, the power distribution module 102 may include: two sets of adapters L3, two sets of first connectors L1, and two sets of second connectors L2. Alternatively, it may include other sets of adapters L3, first connectors L1, and second connectors L2, which are not limited here.

[0124] The set of adapters L3 includes a first adapter L31 and a second adapter L32; the set of first connectors L1 includes a first sub-connector L11 and a second sub-connector L12; the set of second connectors L2 includes a third sub-connector L21 and a fourth sub-connector L22; the first adapter L31 is configured to connect the first sub-connector L11 and the third sub-connector L21; the second adapter L32 is configured to connect the second sub-connector L12 and the fourth sub-connector L22.

[0125] Continue to refer to Figure 7The first adapter L31 includes a first sub-adapter L311, a second sub-adapter L312, and a first contact portion L313; the first contact portion L313 is disposed between the first sub-adapter L311 and the second sub-adapter L312, and connects one end of the first sub-adapter L311 and one end of the second sub-adapter L312; the other end of the first sub-adapter L311 is connected to the first connector L1; and the other end of the second sub-adapter L312 is connected to the second connector L2.

[0126] Continue to refer to Figure 7 The second adapter L32 includes a third sub-adapter L321, a fourth sub-adapter L322, and a second contact portion L323. The second contact portion L323 is located between the third sub-adapter L321 and the fourth sub-adapter L322, and connects one end of the third sub-adapter L321 and one end of the fourth sub-adapter L322. The other end of the third sub-adapter L321 is connected to the first connector L1. The other end of the fourth sub-adapter L322 is connected to the second connector L2.

[0127] In some embodiments, continue to refer to Figure 7 The power distribution module 102 and the conversion module 101 are also used to connect the AC power module and the DC power module 103 so that the AC power module supplies power to the DC power module 103.

[0128] For example, the conversion module 101 includes an AC-DC conversion module 12 and a DC-DC conversion module 11; the AC-DC conversion module 12 is connected to an AC power supply module, and the DC-DC conversion module 11 is electrically connected to a power distribution module 102. The DC-DC conversion module 11 and the power distribution module 102 are used to connect the AC-DC conversion module 12 and the DC power supply module 103, so that the AC-DC conversion module 12 supplies power to the DC power supply module 103. That is, the external power grid can charge the DC power supply module 103 through the charging host 100.

[0129] refer to Figure 13 The AC power module outputs AC power to the AC input module 104, which receives the AC power from the AC power module. Then, the AC input module 104 outputs the AC power to the AC-DC converter module 12 to form DC power. At this time, the output port of the AC-DC converter module 12 is connected to the output port of the DC-DC converter module 11, and the input port of the DC-DC converter module 11 is connected to the DC power module 103 through the power distribution module 102. In this way, the DC power output from the AC-DC converter module 12 can charge the DC power module 103 through the DC-DC converter module 11.

[0130] In other embodiments, the AC power module outputs AC power to the AC input module 104, the AC input module 104 receives the AC power from the AC power source, and then the AC input module 104 outputs the AC power to the AC-DC converter module 12 to form DC power, which is then connected to the DC power module 103 through the power distribution module 102, so that the DC power module 103 can be charged directly.

[0131] For example, in Figure 13 In the charging host shown, in conjunction with the reference Figure 7 The AC power module can be electrically connected to the input terminal of the AC-DC converter module 12, the output terminal of the AC-DC converter module 12 can be connected to the output terminal of the DC-DC converter module 11 through the power distribution module 102, and the output terminal of the DC power module 103 can be connected to the input terminal of the DC-DC converter module 11 through the power distribution module 102, so that the AC power module supplies power to the DC power module 103.

[0132] In this case, continue to refer to Figure 7 The power distribution module 102 further includes: at least one set of adapters L4 and at least one set of first connectors L1; the at least one set of adapters L4 is configured to connect the output terminal of the AC-DC converter module 12 to the output terminal of the DC-DC converter module 11; the at least one set of first connectors L1 is configured to connect the output terminal of the DC power module 103 to the input terminal of the DC-DC converter module 11, so that the AC power module can charge the DC power module 103.

[0133] For example, the power distribution module 102 includes a set of transition bars L4 and a set of first connectors L1. In other embodiments, it may also include two sets of transition bars L4 and two sets of first connectors L1, or other sets of transition bars L4 and first connectors L1.

[0134] The DC-DC converter module 11 has a fifth output terminal and a sixth output terminal; the AC-DC converter module 12 has a third output terminal and a fourth output terminal; and a set of adapters L4 includes a first adapter L41 and a second adapter L42. The first adapter L41 is configured to connect the third output terminal and the fifth output terminal, and the second adapter L42 is configured to connect the fourth output terminal and the sixth output terminal.

[0135] Continue to refer to Figure 7The first adapter bar L41 includes: a first sub-adapter bar L411, a second sub-adapter bar L412, and a third contact portion L413; the third contact portion L413 is disposed between the first sub-adapter bar L411 and the second sub-adapter bar L412, and connects one end of the first sub-adapter bar L411 and one end of the second sub-adapter bar L412; the other end of the first sub-adapter bar L411 is connected to a third output terminal; and the other end of the second sub-adapter bar L412 is connected to a fifth output terminal.

[0136] Continue to refer to Figure 7 The second adapter bar L42 includes: a third sub-adapter bar L421, a fourth sub-adapter bar L422, and a fourth contact portion L423; the fourth contact portion is disposed between the third sub-adapter bar L421 and the fourth sub-adapter bar L422, and connects one end of the third sub-adapter bar L421 and one end of the fourth sub-adapter bar L422; the other end of the third sub-adapter bar L421 is connected to a fourth output terminal; the other end of the fourth sub-adapter bar L422 is connected to a sixth output terminal.

[0137] Understandably, this is in conjunction with references. Figure 7 and Figure 14 When the DC power module 103 supplies power to the DC-DC converter module 11, the third contact L413 disconnects the first sub-transfer bus L411 and the second sub-transfer bus L412, and the fourth contact L423 disconnects the third sub-transfer bus L421 and the fourth sub-transfer bus L422. When it is necessary to integrate the current of the AC power module and the DC power module 103, the first contact L313 connects the first sub-transfer member L311 and the second sub-transfer member L312, and the second contact L323 connects the third sub-transfer member L321 and the fourth sub-transfer member L322.

[0138] Reference Figure 7 and Figure 14 When the charging host 100 supplies power to the DC power module 103, the third contact part L413 connects the first sub-transfer bus L411 and the second sub-transfer bus L412, the fourth contact part L423 connects the third sub-transfer bus L421 and the fourth sub-transfer bus L422, and the first contact part L313 disconnects the first sub-transfer member L311 and the second sub-transfer member L312, and the second contact part L323 disconnects the third sub-transfer member L321 and the fourth sub-transfer member L322.

[0139] In some embodiments, reference Figure 6The housing 10 is equipped with an input port R, which is used to connect an external AC power module. There are at least two input ports R. Having at least two input ports R not only improves the charging efficiency of the charging host 100, but also allows the other input port R to continue to supply power when one of the input ports R fails, thus improving the yield of the charging host 100.

[0140] For example, refer to Figure 6 The number of input ports R can be two, three, or four.

[0141] The charging host 100 provided in the embodiments of this disclosure can be applied in scenarios of charging electric vehicles. The input terminal of the charging host 100 can be connected to an external power grid, and the output terminal can be connected to a charging terminal. The charging host 100 can convert AC power from the external power grid into DC power and then transmit it to the charging terminal. In actual use, the charging terminal can be connected to the charging port of the electric vehicle to replenish the electric vehicle's power.

[0142] In some embodiments, continue to refer to Figure 6 The housing 10 has partitions T inside, forming a receiving cavity Q between the partitions T and the housing 10. Multiple partitions T can divide the receiving cavity Q into multiple compartments C, each compartment C containing at least one module. This division of the receiving cavity Q into multiple compartments C by the partitions T optimizes the space within the housing 10, achieving full utilization. Since at least one module has independent space, the module located in compartment C can be replaced or repaired individually during maintenance and disassembly without being obstructed by adjacent modules or requiring the movement of other modules. Therefore, this improves the convenience of maintaining and disassembling the charging host 100, and reduces the difficulty and cost of maintenance.

[0143] In some embodiments, reference Figure 6 There are at least two receiving cavities Q, and the at least two receiving cavities Q are stacked along the height direction of the housing 10. Since there are at least two receiving cavities Q stacked along the height direction of the housing 10, the space utilization of the receiving cavities Q in the housing 10 is improved, thereby reducing the volume and floor space of the charging host 100, and thus improving the integration of the charging host 100.

[0144] For example, there are two receiving cavities Q, which are stacked along the height of the housing 10. Alternatively, there could be three, four, or five receiving cavities Q.

[0145] In some embodiments, at least two receiving cavities Q are stacked along the height direction of the housing 10. For example, stacking two receiving cavities Q along the height direction of the housing 10 improves the space utilization of the receiving cavities Q in the housing 10, thereby reducing the volume and floor space of the charging host 100, and thus improving the integration of the charging host 100.

[0146] In some embodiments, at least one of the conversion module 101 and the power distribution module 102 is disposed within the receiving cavity Q.

[0147] For example, the conversion module 101 is disposed in the receiving cavity Q, or the power distribution module 102 is disposed in the receiving cavity Q; or the conversion module 101 and the power distribution module 102 are disposed in one receiving cavity Q, or the control module 107 is disposed in the receiving cavity Q.

[0148] For example, the AC input module 104 is disposed in the receiving cavity Q, and the power conversion module 105 is disposed in the receiving cavity Q; or, the AC input module 104 and the conversion module 101 are disposed in one receiving cavity Q; or the conversion module 101, the power distribution module 102, the AC input module 104 and the power conversion module 105 are each disposed in one receiving cavity Q.

[0149] In the charging host 100, each module within the housing 10 is located in an independent cavity Q, ensuring independent protection for each module. If one module fails, it will not directly affect other modules, thus improving the overall stability and safety of the charging host 100. Secondly, separating different modules into different cavities Q facilitates modular management. This not only reduces the complexity of the charging host 100 but also improves its maintainability and scalability. When a module needs updating or repair, it can be more easily located and accessed without interfering with other modules. Thirdly, the independent cavities Q provide independent heat dissipation space for each module, contributing to more effective heat management. For example, some modules may require special heat dissipation solutions, and separating them into different cavities Q makes it easier to meet their heat dissipation needs. Finally, each module occupies an independent cavity Q, which optimizes space utilization to some extent. By planning the size and layout of the cavities Q, the space within the housing 10 can be utilized more effectively while ensuring proper isolation between modules.

[0150] In some embodiments, the partition T located between two adjacent compartments C is provided with a cable passage hole (not shown); the charging host 100 also includes a cable (not shown), which passes through the cable passage hole to connect the modules located in the two adjacent compartments C. In this way, signals between the modules can be transmitted via the cable.

[0151] In some embodiments, the charging host 100 further includes a connector (not shown) disposed on a partition T between two adjacent compartments C. The connector's placement on the partition T improves the cleanliness of the receiving cavity Q and facilitates its location and maintenance by operators.

[0152] The cable includes a first sub-cable and a second sub-cable. One end of the first sub-cable connects to a module in one of two adjacent compartments, and the other end connects to a connector. One end of the second sub-cable connects to a module in the other of two adjacent compartments C, and the other end connects to a connector. This connector connects the modules in two adjacent compartments, improving the ease of connection between modules.

[0153] In some embodiments, the AC-DC converter module 12 is located in a compartment C, which makes the charging host 100 more scalable and upgradable. When it is necessary to increase the charging power or increase the charging speed, it can be achieved by increasing the number of AC-DC converter sub-modules without replacing the entire charging host.

[0154] Since the AC-DC converter module 12 is located in compartment C, when adding an AC-DC converter submodule, it can be directly placed into compartment C without moving other modules, thus improving the convenience of adding AC-DC converter submodules. Similarly, when an AC-DC converter submodule in the AC-DC converter module 12 is damaged, the damaged submodule can be directly removed without moving other modules. Therefore, the ease of assembling and disassembling the charging host 100 is improved.

[0155] In some embodiments, the DC-DC converter module 11 is located in a compartment C, which also makes the charging host 100 more scalable and upgradable. When it is necessary to increase the charging power or increase the charging speed, it can be achieved directly by increasing the number of DC-DC converter sub-modules without replacing the entire charging host.

[0156] Since the DC-DC converter module 11 is located in compartment C, when adding a DC-DC converter submodule, it can be directly placed into compartment C without moving other modules, thus improving the convenience of adding DC-DC converter submodules. Similarly, when a DC-DC converter submodule in DC-DC converter module 101 is damaged, the damaged submodule can be directly removed without moving other modules. Therefore, the ease of assembling and disassembling the charging host 100 is improved.

[0157] In some embodiments, there is a gap between the bottom of the multiple modules and the base plate P. This prevents water from the ground from entering the receiving cavity Q and corroding the multiple modules, thus preventing the charging host 100 from functioning properly.

[0158] Embodiments of this disclosure also provide a charging system 200, with reference to Figure 15 It includes: the charging host 100 described in any of the above embodiments, and the electrical load; the electrical load is connected to the output port of the charging host 100.

[0159] In some embodiments, the electrical load may be a charging pile, a charging gun, or the like. This application does not limit the specific type of electrical load.

[0160] In some embodiments, reference Figure 16 The charging system 200 also includes a DC power supply module, which is connected to the DC-DC converter module (DCDC module) of the charging host 100. The DC power supply module is configured to input a DC signal to the DC-DC converter module (DCDC module).

[0161] The DC power module can increase the output power of the charging host 100. The DC power module directly outputs its own DC power to the DC-DC converter module (DCDC module). This not only solves the problem of the charging host having only one charging mode, but also increases the total power of the charging host 100.

[0162] The above are merely specific embodiments of this application, but the scope of protection of this application is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the scope of the technology disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
