Description

Technical Field

[0001] This utility model relates to the field of charging technology, and in particular to a modular charging terminal and charging pile. Background Technology

[0002] With the rapid development of new energy vehicles, the construction of charging infrastructure has become a crucial factor in promoting the widespread adoption of electric vehicles. Traditional charging terminals often adopt an integrated design, where components such as the charging module, power distribution unit, cooling system, and control unit are all integrated inside a fixed cabinet. While this design can meet basic charging needs, it has many limitations in terms of installation, maintenance, expansion, and troubleshooting.

[0003] First, the maintenance and repair of traditional charging terminals are relatively complex. Due to the tightly integrated internal components, a malfunction typically requires disassembling the entire cabinet, resulting in high repair costs and long repair cycles, impacting normal operation. Furthermore, if a module within the charging terminal fails, maintenance personnel cannot quickly replace individual components (complex maintenance), leading to low operational efficiency (insufficient maintenance convenience). Second, traditional charging terminals have poor scalability. With the continuous growth in charging demand, existing integrated charging terminals often struggle to flexibly adjust power output, failing to meet the needs of different scenarios. For example, in some high-load areas, additional charging modules are needed to increase charging power, but the structure of traditional charging terminals cannot support modular expansion, requiring replacement of the entire device, increasing construction and time costs. In addition, heat dissipation is a key challenge. Charging modules generate significant heat during high-power operation; poor heat dissipation will affect the safety and lifespan of the equipment. Traditional charging terminals typically employ a single air-cooling or water-cooling solution, which is insufficient to accommodate different environments and power requirements, leading to decreased system stability.

[0018] In addition to the first aspect, the cooling unit further includes a second air-cooling unit, which is equipped with a fan system for dissipating internal heat throughout the entire cabinet body through the generated airflow.

[0019] Based on the first aspect, the liquid cooling system unit includes a coolant circulation pipeline, a liquid cooling heat sink, a cooling pump, and a heat exchanger; wherein, the coolant circulation pipeline is used to transport coolant, the liquid cooling heat sink is disposed above the electronic components and carries away the heat generated by the electronic components through the flow of the coolant, and the heat exchanger is connected to the coolant circulation pipeline and is used to transfer the heat absorbed by the coolant to an external cooling medium.

[0033] 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 a part of the embodiments of this application, and not all of the embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.

[0034] It should be noted that related terms such as "first" and "second" can be used to describe various components, but these terms do not limit the component. These terms are only used to distinguish one component from another. For example, without departing from the scope of this utility model, the first component can be referred to as the second component, and the second component can similarly be referred to as the first component. The term "and / or" refers to any one or more combinations of related and descriptive terms.

[0035] Please see Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 This application provides a modular charging terminal 1, which includes a cabinet body 10, a DC / AC input unit 11, an auxiliary power unit 12, a DC output unit 14, and cooling units (15, 16).

[0036] The following describes the structural components of the modular charging terminal 1 of this system:

[0037] The main body of the cabinet 10 may be provided with a cavity including multiple modular installation areas, and the multiple modular installation areas are arranged linearly in the height direction of the main body of the cabinet 10 (for example, the first modular installation area, the second modular area, the third modular area, the fourth modular area, etc. are arranged from top to bottom, and the whole is roughly in a straight line).

[0038] The DC / AC input unit 11 can be a component for receiving power. It is compatible with external AC or DC power (for connecting to external AC or DC power), enabling flexible access to different types of power systems and making it suitable for different charging station application scenarios.

[0039] As an independent modular unit, the auxiliary power unit 12 can process the AC or DC power transmitted by the DC-AC input unit 11 and convert it into a stable DC output (i.e., it has a conversion function to process AC or DC power and output DC power), so that the charging terminal can be adapted to different power grid environments.

[0040] The DC charging output unit 14 can be an output interface that supports multiple DC charging interface standards (e.g., GB / T - Chinese national standard, CCS - European / North American standard, CHAdeMO - Japanese standard), and outputs DC power to electrical equipment through the DC charging output unit 14.

[0041] The cooling units (15, 16) can integrate air cooling and water cooling methods, using either air cooling or water cooling for heat dissipation. Specifically, different heat dissipation methods are selected based on the power output of the charging terminal itself.

[0042] When the modular charging terminal 1 of this system is in operation, the DC / AC input unit 11, auxiliary power unit 12, DC gun output unit 14, and cooling units (15, 16) are located in different modular installation areas. Therefore, each unit can be assembled and tested independently, and then installed in the cabinet for fixed connection. In addition, the modular installation area where the DC / AC input unit 11 is located is equipped with terminal blocks (141, 142). These terminal blocks are detachably connected to the DC / AC input unit 11. Therefore, when the DC / AC input unit 11 needs maintenance or replacement, it is not necessary to disassemble the entire charging terminal cabinet. Replacement can be completed quickly simply by disconnecting the terminal blocks, which greatly reduces maintenance complexity and improves maintenance convenience.

[0043] It should be noted that, depending on actual needs, wiring terminals can also be set in the other modular installation areas of the modular charging terminal 1 of the system, and can be detachably connected to other auxiliary power units 12, DC gun line output units 14, etc. through each wiring terminal.

[0044] In summary, the modular charging terminal of this application adopts a modular installation design, with the DC / AC input unit, auxiliary power unit, DC output unit, and cooling unit located in independent modular installation areas and detachably connected via terminal wiring. Therefore, when a unit malfunctions, it can be replaced or maintained individually without disassembling the entire cabinet (improving maintenance convenience) and significantly reducing maintenance costs and time. Furthermore, since the modular installation areas can be arranged linearly, charging modules, auxiliary power modules, or cooling units can be added or removed according to different application requirements, thereby flexibly adjusting the power output and heat dissipation capacity of the charging terminal to meet charging needs in different scenarios.

[0045] In an optional embodiment of this example, a power transmission component 143 for power transmission is provided in the modular installation area where the DC-AC input unit 11 is located, and the wiring terminals (142, 141) are provided on the input or output port of the power transmission component 143.

[0046] Specifically, the terminal block includes a screw 142 and a copper busbar 141. The copper busbar 141 is detachably connected to the power transmission component 143 via the screw 142. In this embodiment, the copper busbar 141 and the power transmission component 143 are mechanically fastened together by the screw 142, achieving a robust and reliable electrical connection while supporting quick assembly and disassembly. When the DC / AC input unit 11 or the power transmission component 143 requires maintenance, replacement, or upgrade, the copper busbar 141 can be quickly disconnected or reconnected simply by removing the screw 142, simplifying traditional wiring operations and improving equipment maintenance efficiency.

[0047] It should be noted that copper busbar 141, as the main power line, primarily serves to transmit electrical power. Additionally, the screws 142 in the terminal blocks can be adjusted to bolts, clips, or other detachable fasteners depending on the installation requirements.

[0048] In an optional embodiment of this example, the cooling unit may include both a liquid cooling system unit 15 and a first air cooling unit 16. The liquid cooling system unit 15 and the first air cooling unit 16 are disposed in different modular installation areas. The liquid cooling system unit 15 is used for heat dissipation through water cooling, and the first air cooling unit 16 is used for heat dissipation through air cooling.

[0049] Specifically, this embodiment effectively integrates air cooling (for low-current output scenarios) and water cooling (for high-current output scenarios) by configuring a liquid cooling system unit 15 and a first air cooling unit 16, significantly improving the heat dissipation efficiency and system stability of the charging terminal.

[0050] Please see Figure 6 The liquid cooling system unit includes a coolant circulation pipe 152, a liquid cooling heat sink 153, a cooling pump 151, and a heat exchanger 154. In implementation, the coolant circulation pipe 152 is used to transport coolant, the liquid cooling heat sink 153 is disposed above the electronic components and removes the heat generated by the electronic components through the flow of coolant, and the heat exchanger 154 is connected to the coolant circulation pipe and is used to transfer the heat absorbed by the coolant to the external cooling medium.

[0051] Specifically, the liquid cooling system unit 15 drives the coolant to circulate efficiently through the cooling pump 151. Combined with the efficient heat exchange design of the liquid cooling heat sink 153 and the heat exchanger 154, it significantly improves the heat dissipation efficiency of the electronic components inside the charging terminal, reduces the operating temperature, and extends the service life of the core components.

[0052] Please see Figure 7 The first air-cooled unit includes a first heat dissipation channel 162 and a second heat dissipation channel 161. The first heat dissipation channel 162 and the second heat dissipation channel 161 are respectively disposed on opposite sides of the main body of the cabinet and are located in the cold source chamber of the main body of the chassis 10.

[0053] Specifically, the first heat dissipation channel 162 and the second heat dissipation channel 161 can be heat dissipation holes on two side plates on opposite sides of the chassis body 10. The first heat dissipation channel 162 is used to introduce air from outside the chassis body and to draw air out from inside the chassis body through the second heat dissipation channel 161. That is, by forming an effective right-in-left-out air circulation channel, the air cooling function is realized.

[0054] Furthermore, the cooling unit may also include a second air-cooling unit equipped with a fan system 163 located in the power distribution room of the chassis body 10. The fan system 163 can diffuse internal heat throughout the entire chassis body through the generated airflow, thereby driving internal airflow and enhancing the heat dissipation airflow circulation. It can also be combined with the first heat dissipation channel 162 and the second heat dissipation channel 161 to further exhaust heat from the chassis body.

[0055] Specifically, the fan system 163 creates an effective air convection path between the first heat dissipation channel 162 and the second heat dissipation channel 161 by actively drawing in or expelling air. For example, the first heat dissipation channel 162 typically serves as an air intake channel, drawing in cool external air into the cabinet. The fan system 163 accelerates and evenly distributes the airflow, causing the hot air inside the cabinet to quickly flow towards the second heat dissipation channel 161 and be exhausted to the outside of the cabinet through this channel, achieving a continuous and efficient heat dissipation effect.

[0056] In an optional embodiment of this example, the modular installation areas corresponding to the DC gun output unit 14, auxiliary power unit 12, DC-AC input unit 11 and cooling unit (including liquid cooling system unit and air cooling unit) are different and are arranged from top to bottom in the height direction of the main cabinet body.

[0057] Specifically, different functional units are distributed sequentially from top to bottom in different levels of the main cabinet. Each modular installation area is an independent space unit, and different functional modules can be effectively separated by isolation structures to ensure that the electrical system and the heat dissipation system are independent of each other and do not interfere with each other.

[0058] In an optional embodiment of this invention, the modular charging terminal of the system further includes a monitoring unit 13, which is disposed in a modular installation area and is used to control the DC circuit and the cabinet.

[0059] Specifically, the monitoring unit 13 is used to control the on / off state of the DC circuit and centrally manage the overall operating status of the cabinet. It can integrate a control module, a communication module, and a protection module, enabling real-time monitoring and control of the charging terminal system's operating parameters, and automatically controlling the on / off logic of each unit according to set conditions, thus achieving precise charging and discharging management and safety protection functions.

[0060] In an optional embodiment of this example, the front door 17 of the cabinet body 10 is openable.

[0061] Specifically, the front door 17 can be connected to the main body of the cabinet 10 via a pivot or hinge, and supports opening outwards. This allows users or maintenance personnel to easily and quickly access the various modular units inside the cabinet (such as the DC / AC input unit 11, auxiliary power unit 12, DC gun output unit 14, and cooling units 15 and 16) when inspecting, maintaining, or replacing components of the charging terminal.

[0062] Furthermore, the front door 17 not only features a convenient opening mechanism but also complies with multiple international standards and specifications. Specifically, the front door 17 is compatible with at least one of the following three standards: GBT (Chinese National Standard), CE (European Union Standard), and UL (US Safety Standard), ensuring that the entire unit meets the access requirements of different markets and regions. This compatibility with different standards further enhances the international versatility and market adaptability of the modular charging terminal system.

[0063] This application also provides a charging pile, including a charging pile body and a modular charging terminal as described in the above embodiments.

[0064] This utility model presents a modular charging terminal and charging pile system. Through a modular installation design, the DC / AC input unit, auxiliary power unit, DC output unit, and cooling unit are each located in an independent modular installation area and are detachably connected via terminal wiring. Therefore, when a unit malfunctions, it can be replaced or maintained individually without disassembling the entire cabinet (improving maintenance convenience) and significantly reducing maintenance costs and time. Furthermore, because the modular installation area adopts a linear arrangement structure, charging modules, auxiliary power modules, or cooling units can be added or removed according to different application requirements, thereby flexibly adjusting the power output and heat dissipation capacity of the charging terminal to meet charging needs in different scenarios.

[0065] In addition, this utility model also has the following beneficial effects:

[0066] Improve production efficiency: Modular design allows each unit to be produced and tested independently, shortening the production cycle.

[0067] Reduce testing difficulty: Unit tests can be completed before installation, reducing overall system anomalies.

[0068] Simplify maintenance process: Locate the problematic unit through signal feedback, enabling targeted maintenance and reducing maintenance costs.

[0069] The specific embodiments of the utility model have been described in detail above, but they are only examples, and the utility model is not limited to the specific embodiments described above. For those skilled in the art, any equivalent modifications or substitutions to the utility model are also within the scope of the utility model. Therefore, all equivalent transformations, modifications, and improvements made without departing from the spirit and principles of the utility model should be covered within the scope of the utility model.
