Description

Technical Field

[0001] This utility model relates to the field of charging pile technology, and in particular to a full-matrix intelligent output integrated charging pile. Background Technology

[0002] China's largest industrial consumption in the future will be new energy vehicles. Electric vehicles have become a powerful new engine for driving consumption and industrial upgrading. However, charging has become a bottleneck in industrial development, lagging significantly behind the development of electric vehicles. The construction of charging piles has become a prerequisite.

[0003] The limited number of charging stations, slow charging speeds, difficulty in finding charging stations, low utilization rates, range anxiety, and safety concerns have negatively impacted the user experience of pure electric vehicles, hindering the development of new energy vehicles. Therefore, it is necessary to vigorously promote the construction of charging stations.

[0004] Currently, the mainstream DC charging pile equipment on the market is the integrated dual-gun (also known as one-to-two) charging pile equipment. The power of the charging pile is generally between 30kW and 400kW. The smallest granularity of its power distribution is half of the charging power. For example, a 300kW DC dual-gun charging pile composed of a single 30kW charging module can distribute power in a minimum granularity of 150kW per gun, with a maximum output power of 300kW. If two vehicles are charging at the same time, the output power of each gun is 150kW.

[0005] Suppose two vehicles are charging simultaneously. Vehicle A requires 60kW of power, while vehicle B requires 240kW. The charging station cannot meet the demand and can only maintain an output of 150kW from each of the two charging guns. This results in unnecessary waste for vehicle A and increased charging time for vehicle B, leading to a poor customer experience and increased operating costs for the operator. Utility Model Content

[0006] In view of the problems of the existing integrated dual-gun DC charging piles having relatively fixed power distribution, excessively large distribution granularity, and lack of flexibility, resulting in low utilization efficiency and high operating costs, this utility model is proposed.

[0007] Therefore, the purpose of this utility model is to provide a fully integrated intelligent output charging pile with the following objectives: adopting a brand-new power distribution unit so that the power output granularity of each gun is the power of a single module, and each gun can call any number of modules, thereby improving charging efficiency.

[0008] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a full-matrix intelligent output integrated charging pile, including a cabinet and a cabinet door disposed on one side of the cabinet, a touch screen disposed on the top of one side of the cabinet door, a first charging gun disposed on one side of the cabinet, a second charging gun disposed on the side of the cabinet away from the first charging gun, multiple sets of air inlets disposed on one side of the cabinet, multiple sets of air outlets disposed on the side of the cabinet away from the air inlets, a first DC output component disposed on one side of one end of the cabinet's inner cavity, a second DC output component disposed on the other side of one end of the cabinet's inner cavity, a power distribution unit disposed on the top of one end of the cabinet's inner cavity, and a DC charging module disposed on the bottom of one end of the cabinet's inner cavity.

[0009] As a preferred embodiment of the integrated intelligent output charging pile of the present invention, the first DC output component and the second DC output component are composed of a DC fuse, a shunt and a DC contactor.

[0010] As a preferred embodiment of the integrated intelligent output charging pile of the present invention, the first charging gun and the first DC output component of the cabinet cavity are interconnected, and the second charging gun and the second DC output component of the cabinet cavity are interconnected.

[0011] As a preferred embodiment of the integrated intelligent output charging pile of the present invention, the power distribution unit consists of a high-power input terminal, a high-power connector, a program download terminal, a communication connection terminal, a power distribution board, diodes, and a cooling fan.

[0012] As a preferred embodiment of the integrated intelligent output charging pile of the present invention, the DC contactor is interconnected with the power distribution unit through a high-power connector, and the DC charging module is interconnected with the power distribution unit through a high-power input terminal.

[0013] As a preferred embodiment of the integrated intelligent output charging pile of this utility model, the cabinet cavity is equipped with a controller, and the power distribution unit is interconnected with the controller through a communication connection terminal.

[0014] As a preferred embodiment of the integrated intelligent output charging pile of the present invention, the power distribution board is composed of a first output terminal, a second output terminal, an input terminal, a relay, and a chip.

[0015] The beneficial effects of this invention are as follows: The power distribution unit, according to the controller's instructions and the power requirements of different vehicles, can call any number of modules, thus enabling the power output granularity of the first or second charging gun to be that of a single module. Each charging module corresponds to a power distribution board, and each power distribution board can correspond to either the first or second charging gun. When multiple power distribution boards are combined, the high-power connector, power distribution board, and high-power connector are directly connected to diodes, preventing reverse current from flowing into the vehicle battery. This allows the first and second charging guns to intelligently distribute power. When two electric vehicles with different battery capacities or charging needs are connected simultaneously, the charging pile can automatically adjust the output power according to the specific situation of each vehicle, ensuring that each vehicle can be charged at the optimal charging rate. Through reasonable power distribution, the charging time for each electric vehicle can be effectively shortened, and electrical resources can be used more effectively, reducing unnecessary waste. This helps to reduce the operating cost of the entire charging system, potentially lowering the user's charging costs. Attached Figure Description

[0034] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0035] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below. Example

[0036] Reference Figure 1-15 This utility model provides an embodiment of a full-matrix intelligent output integrated charging pile, which includes a cabinet 1 and a cabinet door located on one side of the cabinet 1. It also includes a touch screen 2 located on the top of the cabinet door, a first charging gun 3 located on one side of the cabinet 1, a second charging gun 4 located on the side of the cabinet 1 away from the first charging gun 3, multiple sets of air inlets 5 located on one side of the cabinet 1, multiple sets of air outlets 6 located on the side of the cabinet 1 away from the air inlets 5, a first DC output component 7 located on one side of the inner cavity of the cabinet 1, a second DC output component 8 located on the other side of the inner cavity of the cabinet 1, a power distribution unit 9 located on the top of one end of the inner cavity of the cabinet 1, and a DC charging module 10 located at the bottom of one end of the inner cavity of the cabinet 1.

[0037] The first DC output component 7 and the second DC output component 8 consist of a DC fuse, a shunt, and a DC contactor. The DC fuse is also known as a fast-acting fuse.

[0038] The first charging gun 3 and the first DC output component 7 inside the cabinet 1 are interconnected. The second charging gun 4 and the second DC output component 8 inside the cabinet 1 are interconnected. A DC fuse is connected in series in the DC circuit. When the current in the circuit exceeds its rated value, it will quickly melt and break the circuit, thus protecting the circuit and equipment from damage caused by overload or short-circuit current. The DC fuse plays an important protective role in the circuit, effectively preventing excessive current from damaging the circuit or equipment, and ensuring the stable operation and safety of the power system. A shunt is a resistor used to measure voltage across current, thereby indirectly measuring current. It is based on DC... It is made based on the principle that a voltage is generated across a resistor when current flows through it. In addition, in the field of communications, a shunt also refers to a device that can divide an input signal into multiple output signals to realize signal distribution and delivery. A DC contactor is an electrical switching device used to control the opening and closing of a DC circuit. A DC contactor is a contactor whose iron core is controlled by a DC coil. Its load can be DC or AC. Its working principle is based on the electromagnetic attraction effect. When the contactor coil is energized, the coil current generates a magnetic field, which causes the stationary iron core to generate an electromagnetic attraction to attract the moving iron core, and drive the contacts to act, thereby realizing the closing or opening of the circuit.

[0039] The power distribution unit 9 consists of a high-power input terminal 91, a high-power connector 92, a program download terminal 93, a communication connection terminal 94, a power distribution board 95, a diode 96, and a cooling fan 97.

[0040] The DC contactor is interconnected with the power distribution unit 9 via a high-power connector 92, and the DC charging module 10 is interconnected with the power distribution unit 9 via a high-power input terminal 91.

[0041] The cabinet 1 is equipped with a controller, and the power distribution unit 9 is connected to the controller via communication connection terminal 94.

[0042] The power distribution board 95 consists of a first output terminal 951, a second output terminal 952, an input terminal 953, a relay 954, and a chip 955. The high-power connector 92, the power distribution board 95, and the high-power connector 92 are directly connected to a diode 96 to prevent reverse current from flowing into the vehicle battery.

[0043] During use, the power distribution unit 9 calls any number of modules according to the controller's instructions and the power requirements of different vehicles, and charges the vehicle through the first charging gun 3 and the second charging gun 4. Each charging module corresponds to a power distribution board 95, and each power distribution board 95 can correspond to the first charging gun 3 or the second charging gun 4. When multiple power distribution boards 95 are combined, the high-power connector 92, the power distribution board 95 and the high-power connector 92 are directly connected to the diode 96 to prevent reverse current from flowing into the vehicle battery.

[0044] This allows the power output granularity of the first charging gun 3 or the second charging gun 4 to be the power of a single module. For example, a 300kW integrated DC dual-gun charging pile composed of 15 30kW charging modules has a minimum power granularity of 30kW for each gun, and each gun can call any number of modules.

[0045] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
