Description

Technical Field

[0001] This utility model relates to the field of charging pile technology, specifically a novel overall structure for a charging pile. Background Technology

[0002] With the increasing range of new energy vehicles and the upgrading of energy replenishment efficiency requirements, high-power charging piles (such as those with a capacity of 200kW and above) have become a core component of public charging stations and highway service areas. However, the current high-power charging pile main unit generally suffers from a prominent contradiction in its structural design: "large external size and low internal space utilization," which has become a key pain point restricting product cost control and scenario adaptability.

[0003] In particular, high-power charging pile main units are generally large in size, but their internal structure is not compact enough. The volume density ratio of the components inside the cabinet is low, resulting in too much wasted effective space inside the cabinet, which leads to excessively high overall cost of the charging pile. It also makes the charging pile occupy too much area at the site, resulting in a decline in product competitiveness. Utility Model Content

[0004] The purpose of this utility model is to provide a new type of charging pile structure to solve the problems mentioned in the background art, such as large overall size, insufficient compact layout, wasted space, and high cost of existing charging piles.

The AC side assembly A, from bottom to top, sequentially includes the molded case circuit breaker, AC contactor, terminal assembly, control board, and control mechanism. The molded case circuit breaker has client secondary terminals and surge protection components on both sides, and smart meters are installed on both sides of the AC contactor. The two ends of the molded case circuit breaker and the AC contactor are connected via a circuit breaker.

[0006] Preferably, the AC input terminal and DC output terminal on the charging module are both located on one side of the back of the charging module, and the AC input terminal on the charging module is connected to the AC contactor by a connecting copper busbar.

[0007] Preferably, the negative electrode copper busbar matrix assembly and the positive electrode copper busbar matrix assembly are in a back-to-back structure.

[0008] Preferably, the terminal assembly includes terminals, a power socket, and a residual current circuit breaker.

[0009] Preferably, the control mechanism includes a temperature controller, a leakage controller, and a sensor.

[0010] Preferably, the multiple sets of charging modules are arranged horizontally.

[0011] Compared with existing technologies, the beneficial effects of this utility model are as follows: The new charging pile overall structure involves the charging pile host structure, especially the high-power charging pile host structure.

[0021] It should be noted that with the increasing range of new energy vehicles and the upgrading of energy replenishment efficiency requirements, high-power charging piles (such as those with a capacity of 200kW and above) have become a core configuration for public charging stations and highway service areas. However, the current high-power charging pile main unit generally suffers from a prominent contradiction in its structural design: "large external size and low internal space utilization." This has become a key pain point restricting product cost control and scenario adaptability. In particular, the overall external size of high-power charging pile main units is relatively large, but their internal structural layout is not compact enough, and the volumetric density ratio of components inside the cabinet is low, resulting in too much wasted effective space inside the cabinet and causing the overall cost of the charging pile to be too high. This also makes the charging pile occupy too much area at the charging station, leading to a decrease in product competitiveness.

[0022] To address the aforementioned issues, this solution provides a novel overall structure for charging piles. This application relates to the main unit structure of charging piles, particularly the main unit structure of high-power charging piles. Its internal cabinet structure, through a rational layout and functional area division, results in a more compact and efficient internal structure with higher space utilization. The overall dimensions are more compact; the overall heat dissipation performance is improved, better conforming to thermodynamic principles; the overall wiring is more standardized, rational, and concise, while also saving on cables and reducing cable accumulation. Strong and weak current circuits are separated within the cabinet (main circuit and control circuit are separated), avoiding signal interference. The internal functional modules, through modular design, make installation, disassembly, and maintenance more convenient, operation easier, and more ergonomic.
