Description

Technical Field

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

[0002] Charging piles, also known as electric vehicle charging stations or electric vehicle power supply equipment, are devices that provide electrical energy to electric vehicles, enabling them to store enough electricity to support their operation.

[0003] However, the existing charging gun circuit design has the following problems: 1. The wiring is complex and lacks standardized design; 2. The lack of standardized and reasonable layout of electronic components leads to longer assembly and maintenance cycles, which increases the overall cost of products and reduces market competitiveness in regions with high labor costs. 3. Low transportation costs and low tolerance for errors. Utility Model Content

[0004] The main purpose of this utility model is to propose a modular and maintainable DC charging pile, which aims to modularize the electronic components of the charging pile, thereby enabling modular production, reducing the complexity of the wiring, and improving the feasibility of later assembly and maintenance. Furthermore, this design allows for the disassembly and transportation of individual electronic components, followed by modular assembly in the installation or sales area, thereby reducing transportation costs.

[0005] To achieve the above objectives, this utility model proposes a modular and maintainable DC charging pile, comprising: The cabinet has an inner cavity with a first opening at the front end, and a first partition is provided at the lower part of the inner cavity, which divides the inner cavity into an upper cavity and a lower cavity. The upper cavity is provided with a second partition, which divides the upper cavity into a front cavity and a rear cavity; A first support frame is disposed in the front cavity and is used to install a DC module. A charging module is disposed in a rear cavity, and a second opening is provided on the side wall of the rear cavity. The charging module is installed in the rear cavity through the second opening. The second support frame is used to install the AC module.

[0006] In actual charging cabinets, there are generally DC modules for connecting to the charging modules and controlling the current (such as voltage, current, i.e., power) and AC modules (used to detect the current flow and ensure electrical safety). Therefore, by designing the first support frame, the second support frame, and the charging module, each structure is modularly assembled and produced before being assembled. When the region is far away, they can also be transported in groups, thereby reducing damage to electronic components during transportation. At the same time, the modular design also ensures that subsequent installation and maintenance personnel are easier to train, reducing power usage errors and achieving stable power supply for DC charging piles.

Therefore, features defined with "first" or "second" may explicitly or implicitly include at least one of those features.

[0012] like Figures 1 to 8 As shown, a modular and maintainable DC charging pile includes: Cabinet 1, wherein the cabinet 1 has an inner cavity with a first opening 11 at the front end, and a first partition 2 is provided at the lower part of the inner cavity, the first partition 2 dividing the inner cavity into an upper cavity 21 and a lower cavity 22; The upper cavity 21 is provided with a second partition 3, which divides the upper cavity 21 into a front cavity 31 and a rear cavity 32. First support frame 4, the first support frame 4 is disposed in the front cavity 31, the first support frame 4 is used to install DC module 40; A charging module 7 is disposed in a rear cavity 32, and a second opening 12 is provided on the side wall of the rear cavity 32. The charging module 7 is installed in the rear cavity 32 through the second opening 12. The second support frame 5 is used to install the AC module.

[0013] In actual charging cabinets, there are generally DC modules 40 for connecting to the charging modules 7 and realizing current control (such as voltage, current, i.e., power) and AC modules (used to detect the current on / off state and ensure electrical safety). Therefore, through the design of the first support frame 4, the second support frame 5, and the charging module 7, each structure is modularly assembled and produced before final assembly. This allows for group transportation even in long distances, reducing damage to electronic components during transport. Simultaneously, the modular design facilitates easier training of installation and maintenance personnel, reduces electrical errors, and ensures stable power supply for the DC charging pile. In this embodiment of the utility model, the first support frame 4 includes: An insulating substrate, wherein the insulating substrate is provided with a wire arrangement bar along a predetermined direction. The cable management array includes a closed-loop cable management array 6 distributed along the outer periphery of the insulating substrate, and a first cable management array 61 and a second cable management array 62 distributed at intervals from the height direction of the closed-loop cable management array 6. The first cable management row 61 and the second cable management row 62 divide the insulating substrate into an upper region, a middle region and a lower region. The lower region is provided with a vertically arranged third cable management row 63, which divides the lower region into a left region and a right region.

[0014] The advantages of this application are: 1. First, the cabinet is modularly designed. Then, the cable management system is used to divide the area into reasonable sizes for installing different electrical components. This makes the design clearer during subsequent assembly and maintenance, reduces errors during production, improves installation consistency, and allows less experienced engineers to inspect and maintain the equipment more quickly. This improves the applicability of the equipment and reduces training costs. 2. For production and assembly, it has higher production efficiency, and the matrix-style cable management can also reduce the complexity of the lines.

[0015] In this embodiment of the invention, a DC charging device controller is provided in the upper area, which can control the overall current and voltage and realize current integration.

[0016] Specifically, the central area is equipped with two sets of U-shaped DC modules, thereby enabling the current output of the two charging guns, maximizing space utilization, and ensuring electrical safety.

[0017] In this embodiment of the utility model, the U-shaped DC module includes a first high-voltage DC relay 41 located in the middle, a shunt 43 symmetrically connected to both sides from the first high-voltage DC relay 41, and a second high-voltage DC relay 42 connected to the shunt 43, wherein the first high-voltage DC relay 41, the shunt 43 and the second high-voltage DC relay 42 are connected by copper strips.

[0018] Specifically, the lower area is equipped with a power controller and a DC energy meter to detect the output current, i.e. the output power and power consumption of the charging gun, thereby enabling billing.

[0019] In this embodiment of the utility model, the second support frame 5 has a frame structure, and the AC module includes a miniature residual current circuit breaker 51, a miniature circuit breaker 52, an FV surge protector 53, an intermediate relay 54, and a QF molded case circuit breaker 55.

[0020] This structure primarily functions as an emergency switch and for opening or closing during maintenance. It is typically connected to a DC charging device control unit. This controller is generally a low-voltage device, while the U-shaped DC module is a high-voltage device (its rational layout ensures electrical safety while maximizing space utilization). Through relays and other devices, it achieves low-voltage control of high-voltage, ensuring safe operation, modular installation, and assembly consistency, thus achieving production consistency. Meanwhile, the controller and U-shaped DC module are installed as two separate modules, which can effectively reduce wiring clutter, reduce short circuits and other problems, and improve safety.

[0021] Specifically, the charging module 7 is provided with a handle 72 near the second opening 12. The charging module is equipped with a fan assembly 71 (or another fan assembly 71 can be installed on the entire cabinet 1 to achieve fluid flow), thereby ensuring overall ventilation. The charging module 7 is generally equipped with a hollow structure to ensure ventilation.

[0022] In this embodiment of the utility model, the cabinet 1 is provided with an inclined connector 8, which gradually decreases from the inside to the outside. The connector 8 is used to install the charging gun cable, thereby ensuring electrical safety. For example, when outdoors, it further prevents liquid from entering the cabinet 1. The connector 8 is generally sealed.

[0023] Specifically, the layout of electronic components can be changed according to actual needs.

[0024] Specifically, charging: The charging module converts AC to DC. AC / DC module*1 charges the battery.

[0025] It can both charge and discharge the battery.

[0026] Specifically, the charging module's model number is UR100040-SW. Specifically, the UR100040-SW (EU) charging module can also employ power conversion technology (i.e., European standard), specifically designed for power conversion equipment (e.g., AC / DC) used in electric vehicle charging, featuring an ultra-wide constant power output voltage range. It boasts active power factor correction, high efficiency, high reliability, intelligent control, and an aesthetically pleasing design; the module utilizes intelligent air-cooling technology, achieving high power density while occupying minimal space; and it features hot-swappable and battery recharge protection functions.

[0027] The above description is only a preferred embodiment of the present utility model and does not limit the patent scope of the present utility model. All equivalent structural transformations made under the inventive concept of the present utility model using the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
