[0032] With the rapid development of the new energy vehicle market, the construction scope of charging piles has gradually expanded. As a key energy supply point for new energy vehicles, the development and progress of charging piles have promoted the rapid development of new energy vehicle technology. Charging piles refer to charging equipment that provides charging services for electric vehicles. At present, the most common new energy vehicle fast charging equipment on the market is DC charging piles. DC charging piles have the advantages of high power and high charging efficiency, which is convenient for users to replenish the power of new energy vehicles outdoors in time. Therefore, DC charging piles are widely deployed in public places such as urban roads, service areas, and parking lots.

[0033] However, according to the applicant's observations and research, in the process of factory production of DC charging piles, it is necessary to adjust the design of the charging pile cabinet according to the overall output power of the charging pile, that is, a cabinet of each output power of the charging pile needs to be developed separately. This situation makes the design of DC charging piles more difficult and occupies a large amount of design human resources. At the same time, it also leads to the low comprehensive utilization rate of the same model of charging pile cabinets, thereby increasing the production cost of the charging piles.

[0034] In view of this, it is necessary to propose a charging pile 100 to solve or at least alleviate the above technical problems.

[0035] See also Figure 1 and Figure 2 In one embodiment of the utility model, the charging pile 100 includes a cabinet 1 and a charging compartment assembly 2. Among them, the cabinet 1 includes a first cavity, the charging compartment assembly 2 includes at least two charging modules 21 and a conductive circuit connecting the charging modules 21 in series, and the charging module 21 is arranged in the first cavity. Furthermore, in order to realize the function of flexibly changing the output power of the charging pile 100, the charging module 21 includes a first charging module 21a and a second charging module 21b, and the output power of the first charging module 21a is different from that of the second charging module 21b. At least one of the first charging module 21a and the second charging module 21b is electrically connected to the conductive circuit to change the overall output power of the charging pile 100; the first cavity includes a placement position, and the placement position is used to place the charging module 21, and the number of placement positions is greater than or equal to the number of charging modules 21. The above-mentioned charging module 21 is used to convert alternating current into direct current.

[0036] Specifically, in the present embodiment, the model of the cabinet 1 of the charging pile 100 remains unchanged. Under this premise, two charging modules 21 with different output powers can be installed in the first cavity, namely the first charging module 21a and the second charging module 21b. The first charging module 21a and the second charging module 21b are the same in appearance and size, so they can both be installed in the first cavity without changing the model of the cabinet 1. The charging modules 21 are connected in series through conductive lines to achieve the superposition of current and power between the charging modules 21. According to the change in the installation quantity of the first charging module 21a and the second charging module 21b, the overall output power of the charging pile 100 can be adjusted, so that only one type of cabinet 1 can meet the requirements of more than 100 output powers of the charging pile. In this embodiment, there are eight placement positions for installing the charging module 21. The eight placement positions indicate that a maximum of eight charging modules 21 can be installed in the first cavity, and a partition may be installed or not between two adjacent placement positions as needed; the output power of the first charging module 21a is 30KW, and the output power of the second charging module 21b is 40KW. The manufacturer can combine the installation quantity of the first charging module 21a and the second charging module 21b according to the output power requirement of the charging pile 100. For example, if the output power requirement of the charging pile 100 is 60KW, then only two first charging modules 21a need to be installed in the first cavity, and the number of placement positions is greater than the number of charging modules 21; if the output power requirement of the charging pile 100 is 320KW, eight second charging modules 21b need to be installed in the first cavity, and the number of charging modules 21 is equal to the number of placement positions; if the output power requirement of the charging pile 100 is 200KW, four first charging modules 21a and two second charging modules 21b need to be installed in the first cavity. That is, the first charging module 21a and the second charging module 21b can be connected to the conductive line separately, or they can be connected to the conductive line after being combined to meet the different output power requirements of the charging pile 100. By changing the number of the first charging module 21a and the second charging module 21b installed, the adjustable range of the overall output power of the charging pile 100 in this embodiment is 60KW to 320KW.

[0037] In an embodiment of the utility model, the charging pile 100 includes a cabinet 1 and a charging compartment module, wherein the cabinet 1 includes a first cavity, the charging compartment assembly 2 includes at least two charging modules 21 and a conductive line connecting the charging modules 21 in series, and the charging module 21 is arranged in the first cavity. At the same time, the charging module 21 includes two models of a first charging module 21a and a second charging module 21b, the output power of the first charging module 21a and the second charging module 21b are different, and at least one of the first charging module 21a and the second charging module 21b is electrically connected to the conductive line to change the overall output power of the charging pile 100; the charging module 21 is installed in the placement position in the first cavity, and the number of placement positions is greater than or equal to the number of charging modules 21. The above-mentioned charging module 21 is used to convert alternating current into direct current. Through this arrangement, the manufacturer can flexibly select the number of the first charging module 21a and the second charging module 21b to be used according to the output power requirements of the charging column, thereby changing the output power of the charging pile 100, and the number of placement positions in the cabinet 1 is greater than or equal to the number of charging modules 21, so the model of the cabinet 1 does not need to be changed. That is to say, only one type of cabinet 1 can meet the requirements of different output powers of the charging pile 100, so there is no need to develop a type of cabinet 1 for each charging pile 100 with each output power, thereby saving development resources, improving the utilization rate of the same type of cabinet 1, and reducing production costs.

[0038] Furthermore, in one embodiment of the utility model, the charging compartment assembly 2 also includes a baffle 22, and the baffle 22 is used to cover the placement positions where the charging module 21 is not placed. Specifically, the two ends of the baffle 22 are installed on the cabinet 1 on both sides of the opening of the first cavity. The size of the baffle 22 meets the requirement of being able to completely cover the placement positions in the first cavity, and the two ends of the baffle 22 are detachably connected to the cabinet 1 to facilitate changing the number of installed charging modules 21. Among them, the connection method includes one of screw connection, snap connection, magnetic connection and the like; the material of the baffle 22 needs to be heat-resistant material, such as aluminum alloy. In one embodiment, if there are eight placement positions in the first cavity and six charging modules 21 are installed, there are two vacant placement positions. At this time, the baffle 22 needs to be used to completely cover the two vacant placement positions. Through this arrangement, on the one hand, the intrusion of external impurities into the interior of the charging pile 100 can be reduced, thereby improving the safety of the internal equipment of the charging pile 100 when in use; on the other hand, the detachable design of the baffle 22 makes it more convenient to clean or repair the equipment in the first cavity, and maintenance personnel can easily remove the baffle 22 to clean the first cavity or provide operating space for repairing the charging module 21.

[0039] Furthermore, there are various designs and implementation methods of the baffle 22. In another embodiment of the utility model, the baffle 22 includes a plurality of page panels and positioning hinges. Adjacent page panels are hinged by positioning hinges so that the baffle 22 can extend to different lengths. The plurality of page panels include a first page panel and a second page panel respectively located at both ends. The first page panel is installed on the cabinet 1 above the opening of the first cavity, and the second page panel is provided with a magnetic component, which is used to adsorb the cabinet 1 to fix the baffle 22. Specifically, a positioning hinge is installed between two adjacent page panels. The positioning hinge can automatically adjust the angle of the two adjacent page panels when they are opened and maintain stability without the need for additional support or fixation. The plurality of page panels are hinged together by positioning hinges so that the page panels can stretch freely and can maintain a certain extension length without the assistance of an external mechanical structure. In this embodiment, the maximum extension length of the baffle 22 must be able to cover at least six placement positions. In addition, please refer to Figure 2 , the first page plate is located at the uppermost end of the baffle 22 as a whole, and it is installed on the cabinet 1 above the opening of the first cavity. The connection method with the cabinet 1 can be selected as a fixed connection or a detachable connection according to needs; at the same time, the second page plate is located at the lowermost end of the baffle 22 as a whole, and magnetic suction parts are installed on both sides thereof, which are used to adsorb the cabinets 1 on both sides to fix the lower end of the baffle 22 to prevent shaking. Among them, the magnetic suction parts include one of high-strength permanent magnets and flexible permanent magnets. When installing the charging module 21, it is necessary to install them piece by piece from bottom to top. Therefore, if there is a vacant placement position, the vacant placement position is located above the installed charging module 21. At this time, the baffle 22 is stretched to a suitable length as a whole so that it can completely cover the vacant placement position, and the magnetic suction parts are adsorbed on the cabinets 1 on both sides of the opening of the first cavity, that is, the vacant placement position can be covered. Through this arrangement, on the one hand, the installation order of the baffle 22 and the charging module 21 can be ignored, and the baffle 22 and the charging module 21 can be installed on the charging pile 100 at the same time, thereby improving production efficiency; on the other hand, the extension length of the baffle 22 can be flexibly adjusted, and there is no need to select the installation number of the baffle 22 according to the installation number of the charging module 21, so that only one baffle 22 can be used to adapt to the installation of different numbers of charging modules 21, thereby improving the flexibility of the production process of the charging pile 100; finally, through this arrangement, the maintenance personnel only need to fold up multiple leaf plates to clean the first cavity and repair the equipment, which can further improve the efficiency of the maintenance personnel in maintaining the charging pile 100.

[0040] In one embodiment of the utility model, the cabinet 1 further includes a second cavity, and the charging pile 100 further includes a circuit assembly 3, which is disposed in the second cavity, and the circuit assembly 3 includes an AC input copper bar 31 and an AC output copper bar 32, the AC input copper bar 31 is electrically connected to an external AC power source, and the AC output copper bar 32 is electrically connected to the charging compartment assembly 2. For details, please refer to Figure 1 and Figure 3A second cavity is provided below the first cavity, and a circuit assembly 3 is integrated in the second cavity. The circuit assembly 3 is used to connect an external AC power supply and transmit AC power. An AC input copper bus 31 is provided at the bottom of the second cavity, which is used to connect an external power supply and introduce AC power into the charging pile 100; an AC output copper bus 32 is installed at the top of the second cavity. The AC output copper bus 32 is electrically connected to the charging module 21 and is used to supply AC power to each charging module 21. The AC power is converted into DC power after passing through the charging module 21.

[0041] Furthermore, the circuit assembly 3 also includes a circuit protector 33, and the circuit protector 33 is electrically connected to the AC power input copper busbar 31 and the AC power output copper busbar 32, respectively. In one embodiment of the utility model, the circuit protector 33 includes a molded case circuit breaker or a fuse. When the charging pile 100 is in use, the AC power enters from the AC power input copper busbar 31 and is transmitted to the AC power output copper busbar 32 via the circuit protector 33. The circuit protector 33 is used to cut off the circuit in time when the circuit is overloaded, so as to avoid damage to the electrical equipment in the charging pile 100, extend the service life of the equipment, improve the safety of the equipment, and reduce the cost of repairing and replacing the electrical equipment.

[0042] According to the different overall output power requirements of the charging pile 100, the type of the selected circuit component 3 also needs to be adjusted accordingly.

[0043] In addition, the cabinet 1 also includes a third cavity, and the charging pile 100 also includes a master control component arranged in the third cavity, and the master control component is electrically connected to the circuit component 3 and the charging compartment component 2 respectively. The third cavity is arranged adjacent to the first cavity, and the master control component is electrically connected to the circuit component 3 and the charging compartment component 2. This arrangement facilitates unified management of all operations and monitoring of the charging pile 100, thereby improving the convenience of operation. At the same time, placing the master control component in a separate cavity can provide additional physical protection, reduce accidental damage or unauthorized access, and can also reduce electromagnetic interference, thereby improving the reliability of the entire charging pile 100 system.

[0044] Furthermore, in an embodiment of the present invention, the cabinet 1 further comprises a first opening and a second opening arranged opposite to each other, the first opening cover is provided with a first cabinet door 11, the first cabinet door 11 is provided with an exhaust fan 111, and the exhaust fan 111 is used to extract the hot air in the cabinet 1 and discharge it outward; the second opening cover is provided with a second cabinet door 12, and the second cabinet door 12 is provided with an air inlet 121. For details, please refer to Figure 1A first opening and a second opening are respectively provided on both sides of the cabinet 1. In this embodiment, the opening of the first cavity is the second opening. The first opening and the second opening are arranged opposite to each other on the other side of the cabinet 1. A first cabinet door 11 is installed on one side of the first opening to cover the first opening. At the same time, a second cabinet door 12 is installed on one side of the second opening to cover the second opening. The first cabinet door 11 and the second cabinet door 12 can be hinged doors. A plurality of exhaust fans 111 are installed on the door body of the first cabinet door 11 to extract the hot air in the cabinet 1 and discharge it to the external environment. Matchingly, a plurality of air inlets 121 are provided on the second cabinet door 12. The air inlet 121 can be directly opened on the second cabinet door 12, or can be formed by installing a grille or a shutter on the second cabinet door 12. The air from the external environment passes through the air inlet 121 to take away the heat in the charging pile 100 and returns to the external environment through the exhaust fan 111. Such a cycle can effectively reduce the temperature in the charging pile 100. This arrangement can, on the one hand, facilitate maintenance personnel to clean and repair the equipment inside the cabinet 1; on the other hand, it can effectively reduce the temperature in the cabinet 1 to prevent high temperature from damaging electrical equipment.

[0045] Furthermore, the first cabinet door 11 and the second cabinet door 12 are both provided with a safety switch, and the master control component is electrically connected to each safety switch. When at least one of the first cabinet door 11 and the second cabinet door 12 is opened, the master control component cuts off the power supply to the charging pile 100. Since the charging pile 100 is connected to a high voltage current, it has a greater safety risk. By providing a safety switch on the first cabinet door 11 and the second cabinet door 12, and electrically connecting the safety switch to the master control component, when the maintenance personnel are performing maintenance on the charging pile 100, they can open one of the first cabinet door 11 and the second cabinet door 12 to cut off the power supply to the charging pile 100 as a whole. When both cabinet doors are closed, the charging pile 100 resumes power supply. Such a setting largely ensures the personal safety of the maintenance personnel and avoids electric shock accidents caused by the maintenance personnel forgetting to cut off the power supply.

[0046] In an embodiment of the present invention, the charging pile 100 further includes a DC power collector 4, which is electrically connected to the charging module 21 and the master control assembly for collecting DC power. Figure 1 and Figure 3 The DC bus device 4 is integrated in the second cavity, and the charging module 21 is electrically connected to the DC bus device 4, and the DC bus device 4 is electrically connected to the master control module. The DC bus device 4 is used to collect the DC power generated by each charging module 21, and the DC bus device 4 is electrically connected to the master control component, so that the master control component can control the working state of the DC bus device 4, which is convenient for maintenance personnel to perform separate maintenance on the DC bus device 4.

[0047] Furthermore, the charging pile 100 further includes a charging gun 5, which is electrically connected to the DC power collector 4, and a DC power output end of the charging gun 5 is electrically connected to a charging port of the vehicle. Figure 1 The charging gun 5 can transmit the DC power collected by the DC power collector 4 to the new energy vehicle. When the DC power output end of the charging gun 5 is connected to the charging port of the new energy vehicle, the detection chip in the charging gun 5 sends a signal to the master control component, and the charging pile 100 starts to operate, converting the AC power into DC power and transmitting it to the new energy vehicle. When the charging gun 5 is unplugged from the charging port, the master control component sends a command to stop the operation of the charging pile 100 to avoid waste of resources. When the charging pile 100 is produced, one or two charging guns 5 can be set according to actual needs. It is more convenient for users to use when two charging guns 5 are set.

[0048] The above description is only an exemplary embodiment of the present invention, and does not limit the patent scope of the present invention.
