Description

Technical Field

[0001] This application relates to the field of charging equipment technology, and more specifically, to a charging terminal and a split-type charging system. Background Technology

[0002] With the adjustment of the global energy structure and the increasing awareness of environmental protection, the electric vehicle industry has ushered in explosive growth. As an indispensable supporting infrastructure for electric vehicles, the construction scale and technological development of charging systems are also accelerating. Split charging systems include charging pile main units and charging terminals. The function of the charging pile main unit (referred to as "main unit" in the industry) is to rectify AC power into DC power and output it to the charging terminal (referred to as "terminal" in the industry) for vehicle charging.

[0003] As key components connecting the charging terminal and the electric vehicle and carrying the transmission of electrical energy, the charging gun cable and charging gun have inherent resistance in their internal conductors (such as copper cables). According to Joule's law, when a large current of hundreds of amperes passes through, significant resistance loss will occur. Almost all of this loss is converted into heat energy, causing the temperature of the charging gun cable and charging gun to rise sharply.

[0004] In related technologies, cooling is often achieved by circulating coolant through a liquid cooling system to an integrated liquid cooling circuit within the charging gun cable. While this structure can address the heat dissipation issue of the charging gun cable, the mixing of core electrical components and related devices of the liquid cooling system within the charging terminal cabinet makes the disassembly and maintenance of these components and the liquid cooling system extremely difficult.

[0005] In summary, improving the ease of disassembly and maintenance of internal components in charging terminals has become a technical problem that urgently needs to be solved by those skilled in the art. Utility Model Content

[0104] The core of this application is to provide a charging terminal and a split-type charging system to improve the convenience of disassembling and maintaining the internal components of the charging terminal.

[0105] 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.

[0106] The split-type charging system includes a main unit and a charging terminal arranged separately. The main unit rectifies the AC power into DC power and outputs it to the charging terminal, which is used to charge the vehicle.

[0107] As key components connecting the charging terminal and the electric vehicle and carrying the transmission of electrical energy, the charging gun cable and charging gun have inherent resistance in their internal conductors (such as copper cables). According to Joule's law, when a large current of hundreds of amperes passes through, significant resistance loss will occur. Almost all of this loss is converted into heat energy, causing the temperature of the charging gun cable and charging gun to rise sharply.

[0108] In related technologies, cooling is often achieved by circulating coolant through a liquid cooling system to an integrated liquid cooling circuit within the charging gun cable. While this structure can address the heat dissipation issue of the charging gun cable, the mixing of core electrical components and related devices of the liquid cooling system within the charging terminal cabinet makes the disassembly and maintenance of these components and the liquid cooling system extremely difficult.

[0109] Based on this, one embodiment of this application provides a charging terminal to improve the convenience of disassembling and maintaining the internal components of the charging terminal.

[0110] Specifically, refer to Figure 1 and Figure 2 The charging terminal includes a cabinet 1, core electrical components 2, charging gun wires 3, and a liquid cooling unit 4.

[0111] The cabinet 1 has an inner cavity equipped with a partition 10, which divides the inner cavity of the cabinet 1 into a first chamber 11 and a second chamber 12 distributed sequentially along the height direction of the cabinet 1. Furthermore, to facilitate the installation and maintenance of related components within the cabinet 1, the cabinet 1 generally includes a cabinet body 1a and a cabinet door 1b. The cabinet body 1a has an open opening, and the cabinet door 1b is installed at the open opening of the cabinet body 1a in an openable and closable manner. The specific arrangement of the cabinet door 1b at the open opening of the cabinet body 1a may be, but is not limited to, a hinged connection on one side.

[0112] The core electrical component 2 is located within the second chamber 12. The core electrical component 2 is the main electrical component within the charging terminal's cabinet 1 used to realize the corresponding functions of the charging terminal. Specifically, it may include a power supply module 21, a control circuit module 22, and a main circuit module 23.

[0113] The charging gun line 3 is mainly used to connect the charging gun 5 and the relevant electrical components of the core electrical component 2. A liquid cooling circuit for cooling the charging gun line 3 is provided on the outside of the charging gun line 3. Specifically, the liquid cooling circuit can be integrated into the charging gun line 3, but is not limited to that in the charging gun line 3.

[0114] The liquid cooling unit 4 is located in the first chamber 11 and is used to circulate coolant into the liquid cooling circuit. Its main function is to transport the cooled coolant to the liquid cooling circuit and to receive the coolant left over after heat exchange in the liquid cooling circuit.

[0115] In practical applications, this charging terminal, on the one hand, circulates coolant to the liquid cooling circuit set outside the charging gun line 3 through the liquid cooling unit 4, which can achieve liquid cooling heat dissipation of the charging gun line 3 and meet the heat dissipation requirements of the charging gun line 3; on the other hand, since the liquid cooling unit 4 is set in the first chamber 11 and the core electrical component 2 of the charging terminal is set in the second chamber 12, and the first chamber 11 and the second chamber 12 are two chambers distributed sequentially along the height direction of the cabinet 1, the core electrical component 2 and the liquid cooling unit 4 can be arranged in layers, reducing the difficulty of disassembly and assembly due to mutual interference during installation and maintenance, and helping to improve the convenience of disassembly and maintenance of the core electrical component 2 and the liquid cooling unit 4.

[0116] In addition, since the core electrical components 2 and the liquid cooling unit 4 are arranged in separate chambers, the mutual interference between them during operation is effectively reduced. For example, since the first chamber 11 and the second chamber 12 are distributed along the height of the cabinet 1, the problem that the liquid cooling unit 4 may affect the normal operation of the core electrical components 2 due to leakage of coolant is effectively reduced.

[0117] As mentioned above, continue to refer to Figure 1 and Figure 2 The core electrical component 2 mainly includes a power supply module 21, a control circuit module 22, and a main circuit module 23. The power supply module 21 converts high-voltage DC to low-voltage DC (e.g., 24V or 12V) to power the low-voltage circuit in the control circuit module 22. The control circuit module 22 is responsible for intelligent control of the entire charging process, specifically including multiple safety protection strategies such as overvoltage protection, overcurrent protection, leakage detection, and emergency stop response. It also interacts with the cloud platform via 4G / Ethernet communication methods to achieve remote monitoring and fault diagnosis. The main circuit module 23 is the main path for energy transmission, referring to... Figure 7Specifically, it may include components such as a high-voltage DC contactor 232, a fuse 234, an electricity meter 235, and a copper busbar 233, through which high voltage and high current flow. Finally, the energy injection into the electric vehicle is completed through the charging gun 5.

[0118] Continue to refer to Figure 1 and Figure 2 To achieve a more rational layout of the core electrical components 2 within the second chamber 12, in this embodiment, the power module 21 can be optionally mounted on the first side wall 121 within the second chamber 12, the main circuit module 23 can be optionally mounted on the second side wall 122 within the second chamber 12, and the control circuit module 22 can be optionally mounted on the third side wall 123 within the second chamber 12. The first and second side walls 121 and 122 are two opposing side walls along the width of the cabinet 1 within the second chamber 12, and the third side wall 123 is the inner side wall along the depth of the cabinet 1 within the second chamber 12. This layout fully utilizes the space within the cabinet 1. It is understood that this layout is merely an example of this embodiment; in actual applications, other layout methods can be selected according to actual arrangement requirements, and no further specific limitations are made here.

[0119] In a further implementation plan, refer to Figure 1 The second chamber 12 may also be equipped with a turbulence fan module 6, which is mounted on the first side wall 121 and located below the power supply module 21. The main function of this turbulence fan module 6 is to turbulent the airflow within the second chamber 12 to enhance the contact between the airflow and the interior of the cabinet 1, while simultaneously reducing localized overheating, such as that affecting the power supply module 21. Figure 2 The main circuit module 23 shown can approach the airflow under the action of the turbulence fan module 6, thereby improving heat dissipation performance.

[0120] In a further implementation plan, refer to Figure 4 As shown, the aforementioned turbulence fan module 6 may specifically include a fan mounting bracket 61, a fan body 62, and a fan adapter plate 63, combined with... Figure 1 Specifically, the aforementioned fan mounting bracket 61 can be installed on the first side wall 121. Both the fan body 62 and the fan adapter plate 63 are mounted on the fan mounting bracket 61. The fan adapter plate 63 is electrically connected to the fan body 62 for transmitting control signals. The design of the fan mounting bracket 61 makes the installation of the fan body 62 more convenient and facilitates the design of its installation angle and position.

[0121] In a further implementation plan, the following reference will continue to be made. Figure 4 Combination Figure 1The aforementioned fan mounting bracket 61 may specifically include a first bracket 611 and a second bracket 612. The first bracket 611 is disposed on the first sidewall 121, forming an airflow channel with the first sidewall 121. The airflow channel has a first ventilation opening 6111 facing the power module 21. The fan adapter plate 63 is disposed on the side of the first bracket 611 facing away from the first sidewall 121. The airflow channel can generate a certain heat dissipation effect on the fan adapter plate 63, and the first ventilation opening 6111 facing the power module 21 can enhance the disturbance effect on the thermal boundary airflow of the power module 21. One end of the second bracket 612 is connected to the first bracket 611, and the other end is connected to the first sidewall 121. The second bracket 612 has a second ventilation opening 6121, and the fan body 62 is disposed at the second ventilation opening 6121. By designing the second bracket 612, the installation angle of the fan body 62 can be tilted to better meet the heat dissipation requirements of devices with high heat generation.

[0122] For example, refer to Figure 4 Combination Figure 1 Specifically, the second vent 6121 can be designed to tilt downwards and face the main circuit module 23, so that the main circuit module 23 is located on the air inlet side or air outlet side of the fan body 62, thereby helping to improve the heat dissipation effect of the main circuit module 23. For example, if the main circuit module 23 is located on the air inlet side of the fan body 62: the airflow direction generated by the fan body 62 under the action of the first vent 6111 and the second vent 6121 can be from the side where the main circuit module 23 is located to the side where the power module 21 is located; or if the main circuit module 23 is located on the air outlet side of the fan body 62: the airflow direction generated by the fan body 62 under the action of the first vent 6111 and the second vent 6121 can be from the side where the power module 21 is located to the side where the main circuit module 23 is located.

[0123] In some other specific implementation schemes, refer to Figure 3 Combination Figure 1 As shown, the power module 21 may specifically include a power mounting bracket 211, a power connector 212, and a power body 213. The power mounting bracket 211 is disposed on the first side wall 121, and the power body 213 is mounted on the power mounting bracket 211 via the power connector 212. The power mounting bracket 211 may be disposed on the first side wall 121 by welding, for example, by fastener connection. The power connector 212 may be connected to the power body 213 and the power mounting bracket 211 by fastening, for example, the power connector 212 may be designed as an integral sheet metal structure with the power mounting bracket 211. By designing the power module 21 with the above-described structure, the disassembly, assembly, and maintenance of the power module 21 are made more convenient.

[0124] Additionally, refer to Figure 3 Combination Figure 1 As shown, the number of power modules 21 can be one or more (i.e., at least two). When there are multiple power modules 21, they can be arranged in a way that is along the height of the cabinet 1, which makes installation and arrangement convenient.

[0125] In some specific implementation plans, refer to Figure 6 As shown, the control loop module 22 may specifically include a control loop mounting plate 221, a network module 222, a high voltage acquisition unit 223, a circuit protection device 224, and an electrical connection device 225.

[0126] Among them, reference Figure 6 Combination Figure 1 As shown, the control loop mounting plate 221 is mounted on the third side wall 123, and the mounting method can be, but is not limited to, fastener connection. The network module 222, high-voltage acquisition unit 223, circuit protection device 224, and electrical connection device 225 are all mounted on the control loop mounting plate 221, and the mounting method can be, but is not limited to, fastener connection. In addition, the high-voltage acquisition unit 223 can be designed to be located below the network module 222, and the circuit protection device 224 and electrical connection device 225 can be optionally located below the high-voltage acquisition unit 223. This layout makes full use of the space in the second chamber 12 and facilitates the connection and wiring of related electrical components.

[0127] In a further implementation plan, refer to Figure 6 As shown, the control circuit mounting plate 221 can be equipped with mounting rails 226 extending along the width of the cabinet 1. Both the circuit protection device 224 and the electrical connection device 225 can be connected to the mounting rails 226 via a snap-fit ​​connection. This snap-fit ​​connection design makes the disassembly and maintenance of the circuit protection device 224 and the electrical connection device 225 more convenient.

[0128] In some other specific implementation schemes, refer to Figure 7 As shown, the main circuit module 23 may specifically include a main circuit mounting plate 231, a high-voltage DC contactor 232, a copper busbar 233, a fuse 234, and an electricity meter 235.

[0129] Among them, reference Figure 7 Combination Figure 2The main circuit mounting plate 231 can be specifically mounted on the second side wall 122, and the mounting method can be, but is not limited to, fastening with fasteners. The high-voltage DC contactor 232 is mounted on the main circuit mounting plate 231, and the mounting method can be, but is not limited to, fastening with fasteners. The copper busbar 233 is mounted on the side of the high-voltage DC contactor 232 facing away from the main circuit mounting plate 231, and the fuse 234 and the energy meter 235 are mounted on the copper busbar 233. Insulators 237 can be mounted on the wiring side of the copper busbar 233 and fixed to the corresponding position on the second side wall 122 to strengthen insulation. Corresponding terminals 236 can also be designed on the wiring side of the copper busbar 233. For example, the bottom end of the copper busbar 233 can be connected to the terminal 236 with fasteners for easy wiring. This design makes the main circuit module 23 a complete modular structure, facilitating overall assembly and disassembly, and making maintenance more convenient.

[0130] In some specific implementation plans, refer to Figure 1 At least one of the first sidewall 121, the second sidewall 122, and the third sidewall 123 may be provided with a cable management assembly 7. The cable management assembly 7 is used to organize the connecting cables between the relevant electrical components of the core electrical component 2. The specific structural form of the cable management assembly 7 may be designed as a cable tie structure, but is not limited to it. For example, it may also be designed as a cable management channel structure. Its specific arrangement position can be designed according to the fixing position requirements of the cables and cooling pipes. For example, it may be designed as... Figure 1 Below the power module 21 shown, and below the charging gun wire 3 that exits the cabinet 1.

[0131] In some specific implementation plans, refer to Figure 1 Combination Figure 5 As shown, a connecting bracket 101 can be provided on the outer edge of the partition 10. The connecting bracket 101 is used to connect with the inner wall of the cabinet 1. The connecting bracket 101 can be designed as an integral structure with the partition 10, or it can be designed as a separate connection structure. For example, it can be designed to be fastened to the partition 10. Then, the connecting bracket 101 can be welded to the inner wall of the cabinet 1, or it can be fixed to the inner wall of the cabinet 1 by fasteners.

[0132] In addition, continue to refer to Figure 1 Combination Figure 5 As shown, a wiring hole 102 can also be provided on the partition 10. The wiring hole 102 connects the first chamber 11 and the second chamber 12. The main function of the wiring hole 102 is to allow the passage of the connecting pipe between the liquid cooling circuit and the liquid cooling unit 4, as well as the passage of the corresponding cables. Its specific arrangement and shape can be designed according to actual needs, and no further specific limitations are made here.

[0133] In some other specific implementation schemes, refer to Figure 8 As shown, the liquid cooling unit 4 may specifically include a liquid cooling system mounting bracket 41, a liquid cooling system 42, and a cooling fan 43. Among these, combined with... Figure 1 and Figure 2 The liquid cooling system mounting bracket 41 is disposed on the chamber wall of the first chamber 11, and the liquid cooling system 42 and the cooling fan 43 are both disposed on the liquid cooling system mounting bracket 41; and the liquid cooling system 42 is connected to the liquid cooling circuit for circulating and supplying coolant to the liquid cooling circuit, and the cooling fan 43 is used to air cool the liquid cooling system 42.

[0134] In a further implementation plan, refer to Figure 1 and Figure 2 The aforementioned first chamber 11 has an air inlet 111 and an air outlet 112, which are respectively disposed on two opposite side walls of the first chamber 11 along the width direction of the cabinet 1. Both the air inlet 111 and the air outlet 112 are equipped with dustproof mechanisms 8. By designing the dustproof mechanisms 8, the air inlet 111 and the air outlet 112 can provide better dust protection for the first chamber 11 while meeting its heat dissipation requirements.

[0135] The cooling fan 43 can be designed to be arranged near the air inlet 111 or near the air outlet 112. Alternatively, there can be multiple cooling fans 43, with some arranged near the air inlet 111 and others near the air outlet 112, as long as the airflow entering from the air inlet 111 is transported to the air outlet 112. In actual application, the arrangement can be selected according to actual needs.

[0136] In a further implementation plan, refer to Figure 9 As shown, the dustproof mechanism 8 can specifically include a louver frame 81 and a dustproof net 82. The louver frame 81 includes a frame body 811 and louvers 812 disposed within the frame body 811. The dustproof net 82 is disposed on one side of the louver frame 81 and is sealed to the frame body 811. The sealing connection method can be, but is not limited to, designing a sealing strip 83 between the two. The specific way in which the dustproof net 82 is disposed on the louver frame 81 can be achieved by designing a corresponding dustproof net connector 84. The dustproof net connector 84 can be, but is not limited to, designed as a pressure plate structure.
