Description

Technical Field

[0001] The present application relates to the technical field of charging equipment, and in particular to a multi-channel matrix power distribution device and charging equipment. Background Art

[0002] With the transformation of the global energy structure and growing environmental awareness, electric vehicles, as green transportation, are gradually becoming an important direction for future transportation development. The popularization of electric vehicles is inseparable from efficient and convenient charging infrastructure. Charging piles are key equipment for electric vehicle charging. Their performance and functions directly affect the user experience and the speed of electric vehicle adoption.

[0003] In high-traffic and high-charging demand scenarios like public charging stations and highway service areas, traditional ring and star parallel configurations cannot meet flexible distribution requirements. Using a traditional matrix power distribution layout results in large volumes and low pile space utilization. Consequently, multiple outputs increase the number of electrical components, and rationally arranging these components within a limited space to maintain a small and compact charging pile is a design challenge. Furthermore, the safety and reliability of charging piles are crucial design considerations. Preventing electrical failures caused by multiple outputs and ensuring long-term stable operation of the equipment presents another challenge in multi-output charging pile design.

[0004] In summary, existing charging piles have technical problems such as large size, low space utilization, and insufficient safety and reliability. Utility Model Content

[0005] In view of the technical problems existing in the background technology, the present application provides a multi-way matrix power distribution device and a charging device. The multi-way matrix power distribution device not only meets the needs of charging multiple electric vehicles at the same time, but also maintains the overall small size and compact structure of the charging equipment, and effectively improves the safety and reliability of the charging equipment.

[0006] In a first aspect, an embodiment of the present application provides a multi-channel matrix power distribution device, including a base plate, a plurality of DC contactors, and a plurality of output copper bars:

[0007] base plate;

[0008] A plurality of DC contactors are mounted on the base plate;

[0009] A plurality of output copper bars are arranged at intervals, and any two of the output copper bars are connected via one DC contactor.

[0010] The technical solution in the embodiments of this application features a multi-output structural layout. Through the rational layout of the multi-output copper busbars and DC contactors, each output copper busbar can reach another output copper busbar through the DC contactor, while also maintaining a compact overall footprint. Through optimized circuit design and layout, high flexibility and scalability are achieved, enabling efficient and stable charging services for multiple electric vehicles simultaneously. This solution not only meets the needs of charging multiple electric vehicles simultaneously, but is also suitable for various scenarios, such as public charging stations, homes, and businesses, catering to the needs of diverse users. It also maintains the overall small size and compact structure of the charging pile. The innovative structural layout and compact design significantly reduce the footprint of the charging pile, lowering installation and maintenance costs and improving overall reliability and service life. Furthermore, through optimized circuit design and an intelligent management system, the charging pile also features functions such as automatic power distribution, charging status monitoring, fault detection, and timely protection, further enhancing user experience and safety. This solution effectively improves the safety and reliability of charging piles, providing strong technical support for the popularization of electric vehicles.

[0011] In some embodiments of the present application, a plurality of conductive copper bars are further included. Each of the DC contactors has two contacts at one end away from the base plate. Each of the conductive copper bars connects one of the contacts to one of the output copper bars.

[0012] In this embodiment, each of the DC contactors corresponds to two conductive copper bars, which are connected to the two output copper bars via the two conductive copper bars. Connecting the contacts of the DC contactor to the output copper bars via the conductive copper bars can improve the reliability and stability of the connection and reduce the possibility of poor contact or loose connection. The conductive copper bars have high electrical conductivity, which can reduce thermal resistance, thereby improving heat conduction efficiency, helping to dissipate heat and maintain the device operating within a suitable temperature range. In the case of multiple outputs, the voltage and current of each output are ensured to be stable and there is no interference between the outputs. This embodiment ensures the stability and independence of each output by optimizing the circuit design and the rational layout of the DC contactors.

[0013] In some embodiments of the present application, the multiple output copper bars are parallel to each other, the multiple conductive copper bars are parallel to each other, and the extension direction of any output copper bar is perpendicular to the extension direction of any conductive copper bar.

[0014] In this embodiment, all output copper buses extend along a first direction, and all conductive copper buses extend along a second direction. When the first direction and the second direction are perpendicular to each other, the device forms a matrix power distribution layout. The parallel arrangement design makes the connections between the various components clearly visible, which is convenient for maintenance personnel to inspect and maintain. The vertical connection direction helps to reduce safety hazards that may be caused by the crossing of internal lines of the equipment, such as short circuits or arcs, thereby improving the safety of the system. The matrix arrangement of output copper buses and conductive copper buses can make more efficient use of space, especially in the design of compact charging piles. This layout can reduce the footprint of the equipment and make the equipment more compact.

[0015] In some embodiments of the present application, the plurality of DC contactors are arranged in multiple rows at intervals, and the DC contactors in each row are located between two adjacent output copper bars.

[0016] In this embodiment, all output copper bars extend along a first direction, and the DC contactors in the same row are also spaced apart along the first direction. Placing the DC contactors in the gaps between two output copper bars allows for more efficient use of space, avoiding an increase in the overall spacing between the DC contactors and the output copper bars, thereby reducing the equipment's footprint. Placing the DC contactors between adjacent output copper bars effectively reduces the extended length of the conductive copper bars, lowering resistance and thus reducing electrical conduction losses, thereby improving transmission efficiency and mitigating the risk of heat buildup.

[0017] In some embodiments of the present application, the DC contactors in two adjacent columns are staggered with each other, and the conductive copper bars on different DC contactors are arranged at intervals.

[0018] In this embodiment, all conductive copper busbars extend along the second direction, and the conductive copper busbars of different DC contactors are spaced a certain distance apart in the first direction. This spacing effectively reduces the risk of short circuits between adjacent contactors due to DC contactor failure, thereby improving system safety. It also helps reduce electromagnetic interference. While the conductive copper busbars and output copper busbars generate a certain electromagnetic field during the construction process, this field has a minimal impact on other copper busbars outside the safe spacing, thereby improving system reliability.

[0019] In some embodiments of the present application, the output copper busbar is arranged opposite to the base plate, and the DC contactor is located between the base plate and the output copper busbar.

[0020] In this embodiment, the output copper busbar is arranged opposite to the base plate, and the DC contactor and the conductive copper busbar are arranged between the two, which effectively utilizes the height space and reduces the footprint of the device, thereby optimizing the overall layout and making the equipment more compact.

[0021] In some embodiments of the present application, a plurality of insulating columns are further included, which are installed on the base plate and correspondingly arranged on one side of the multiple columns of DC contactors, and each of the output copper busbars is fixedly connected to one end of the insulating column away from the base plate.

[0022] In this embodiment, the use of insulating posts prevents current from directly contacting the baseplate or other structures, thereby avoiding potential electric shock hazards and improving system safety. Securing the output copper busbar with insulating posts reduces loosening or disconnection caused by vibration or temperature changes, thereby improving system reliability.

[0023] In some embodiments of the present application, the number of the output copper bars is n, and the number of the DC contactors is C(n, 2).

[0024] In this embodiment, C(n, 2) represents the number of ways to connect two output busbars from n, or the number of combinations. These C(n, 2) combinations provide multiple possibilities for connecting the output busbars, allowing the most appropriate connection method to be selected based on actual needs to meet different charging requirements. By combining different connection methods, the system can increase or decrease the number of output busbars as needed, achieving flexible scalability. The C(n, 2) connection methods reduce the risk of system failure due to a single connection path failure because multiple backup connection paths are available. These C(n, 2) connection methods allow for more efficient arrangement of output busbars and DC contactors within a limited space, reducing the equipment footprint.

[0025] In some embodiments of the present application, the number of the output copper bars is 6, and the number of the DC contactors is 15.

[0026] In this embodiment, the device includes six output copper bars and fifteen DC contactors, so that each DC contactor is connected to two different output copper bars, and a DC contactor is provided between any two output copper bars.

[0027] This embodiment provides high redundancy through multiple connection methods. This means that even if one output busbar fails, the system can continue to operate by connecting to another output busbar, thereby improving system reliability. When combined with an intelligent management system, when multiple electric vehicles are charging simultaneously, the power distribution of each output can be dynamically adjusted based on the charging needs of each electric vehicle, achieving efficient distribution of limited charging power, improving overall charging efficiency, and reducing charging time.

[0028] In a second aspect, an embodiment of the present application provides a charging device, comprising a multi-way matrix power distribution device as described in any embodiment of the first aspect.

[0029] In the technical solution of the embodiments of the present application, a compact design of the overall structure of the charging pile is achieved through the rational layout of internal components. The layout of each output port and DC contactor has been optimized to maximize the use of internal space and reduce the size of the equipment. The modular design allows for compact connections between modules without mutual interference, facilitating installation and maintenance, and is particularly suitable for installation environments with limited space. This provides an efficient, stable, safe, and compact multi-output structural layout solution for charging piles, providing technical support for the popularization of electric vehicles and the development of charging infrastructure.

[0048] In view of the technical problems existing in the background technology, the present application provides a multi-way matrix power distribution device and a charging device. The multi-way matrix power distribution device not only meets the needs of charging multiple electric vehicles at the same time, but also maintains the overall small size and compact structure of the charging equipment, and effectively improves the safety and reliability of the charging equipment.

[0049] In a first aspect, the present invention provides a multi-channel matrix power distribution device, such as Figure 1 and Figure 2 As shown, Figure 1 This is a structural diagram of a multi-channel matrix power distribution device in an embodiment of the present application; Figure 2 This is an exploded schematic diagram of a multi-channel matrix power distribution device in an embodiment of the present application.

[0050] A multi-channel matrix power distribution device includes a base plate 100, multiple DC contactors 200, and multiple output copper bars 300:

[0051] Base plate 100;

[0052] A plurality of DC contactors 200 are mounted on the base plate 100;

[0053] A plurality of output copper bars 300 are arranged at intervals, and any two output copper bars 300 are connected via one DC contactor 200 .

[0054] The technical solution of the embodiments of the present application features a multi-output structural layout. Through the rational layout of the multi-output copper busbar 300 and the DC contactor 200, each output copper busbar 300 can reach another output copper busbar 300 through the DC contactor 200, while maintaining a relatively small overall device size.

Furthermore, through optimized circuit design and an intelligent management system, the charging pile also features functions such as automatic power distribution, charging status monitoring, fault detection, and timely protection, further enhancing user experience and safety. This solution effectively improves the safety and reliability of charging piles, providing strong technical support for the popularization of electric vehicles.

[0055] like Figure 3 As shown, Figure 3 Schematic diagram of the structure of a DC contactor 200 in an embodiment of the present application.

[0056] like Figure 1 and Figure 2 As shown, in some embodiments of the present application, a plurality of conductive copper bars 500 are further included. Each of the DC contactors 200 has two contacts at one end away from the base plate 100 , and each of the conductive copper bars 500 connects one of the contacts to one of the output copper bars 300 .

[0057] In this embodiment, each of the DC contactors 200 corresponds to two conductive copper bars 500 and is connected to two output copper bars 300 through the two conductive copper bars 500. By connecting the contacts of the DC contactors 200 and the output copper bars 300 through the conductive copper bars 500, the reliability and stability of the connection can be improved, and the possibility of poor contact or loose connection can be reduced. The conductive copper bars 500 have high electrical conductivity, which can reduce thermal resistance, thereby improving heat conduction efficiency, helping to dissipate heat and maintain the equipment running within a suitable temperature range. In the case of multiple outputs, it is ensured that the voltage and current of each output are stable, and that there is no interference between the various outputs. The present embodiment ensures the stability and independence of each output by optimizing the circuit design and the reasonable layout of the DC contactors 200.

[0058] In some embodiments of the present application, the multiple output copper bars 300 are parallel to each other, the multiple conductive copper bars 500 are parallel to each other, and the extension direction of any output copper bar 300 is perpendicular to the extension direction of any conductive copper bar 500.

[0059] In this embodiment, all output copper buses 300 extend along a first direction, and all conductive copper buses 500 extend along a second direction. When the first direction and the second direction are perpendicular to each other, the device forms a matrix power distribution layout. The parallel arrangement design makes the connections between the various components clearly visible, which is convenient for maintenance personnel to inspect and maintain. The vertical connection direction helps to reduce safety hazards that may be caused by the crossing of internal lines of the equipment, such as short circuits or electric arcs, thereby improving the safety of the system. The matrix arrangement of output copper buses 300 and conductive copper buses 500 can make more efficient use of space, especially in the design of compact charging piles. This layout can reduce the footprint of the equipment and make the equipment more compact.

[0060] In some embodiments of the present application, the plurality of DC contactors 200 are arranged in multiple rows at intervals, and the DC contactors 200 in each row are located between two adjacent output copper bars 300 .

[0061] In this embodiment, all output copper bars 300 extend along a first direction, and the DC contactors 200 in the same row are also spaced apart along the first direction. Placing the DC contactors 200 in the gap between two output copper bars 300 allows for more efficient space utilization, avoiding an increase in the overall spacing between the DC contactors 200 and the output copper bars 300, thereby reducing the equipment's footprint. Placing the DC contactors 200 between adjacent output copper bars 300 effectively reduces the extended length of the conductive copper bars 500, lowering resistance and thus reducing electrical conduction losses, thereby improving transmission efficiency and mitigating the risk of heat buildup.

[0062] In some embodiments of the present application, the DC contactors 200 in two adjacent columns are staggered with each other, and the conductive copper bars 500 on different DC contactors 200 are arranged at intervals.

[0063] In this embodiment, all conductive copper bars 500 extend along the second direction, and the conductive copper bars 500 of different DC contactors 200 are spaced a certain distance apart in the first direction. This spacing design effectively reduces the risk of short circuits between adjacent contactors due to a DC contactor 200 failure, thereby improving system safety. It also helps reduce electromagnetic interference. Because the conductive copper bars 500 and the output copper bars 300 generate a certain electromagnetic field during operation, this electromagnetic field has little impact on other copper bars outside the safe distance, thereby improving system reliability.

[0064] In some embodiments of the present application, the output copper busbar 300 is disposed opposite to the base plate 100 , and the DC contactor 200 is located between the base plate 100 and the output copper busbar 300 .

[0065] In this embodiment, the output copper bus 300 is arranged opposite to the base plate 100, and the DC contactor 200 and the conductive copper bus 500 are arranged between the two, which effectively utilizes the height space and reduces the footprint of the device, thereby optimizing the overall layout and making the equipment more compact.

[0066] In some embodiments of the present application, a plurality of insulating columns 400 are further included. The plurality of insulating columns 400 are installed on the base plate 100 and are correspondingly arranged on one side of the plurality of columns of DC contactors 200. Each of the output copper busbars 300 is fixedly connected to one end of the insulating column 400 away from the base plate 100.

[0067] In this embodiment, the use of insulating posts 400 prevents current from directly contacting the base plate 100 or other structures, thereby avoiding potential electric shock hazards and improving system safety. By securing the output copper busbar 300 with insulating posts 400, loosening or disconnection caused by vibration or temperature changes can be reduced, thereby improving system reliability.

[0068] In some embodiments of the present application, the number of the output copper bars 300 is n, and the number of the DC contactors 200 is C(n, 2).

[0069] In this embodiment, C(n, 2) represents the number of ways to connect two output busbars 300 from n output busbars 300, or the number of combinations. The C(n, 2) combination provides multiple possibilities for connecting the output busbars 300, allowing the most appropriate connection method to be selected based on actual needs to meet different charging requirements. By combining different connection methods, the system can increase or decrease the number of output busbars 300 as needed, achieving flexible scalability. The C(n, 2) connection methods reduce the risk of system failure due to a single connection path failure because multiple backup connection paths are available. Using these C(n, 2) connection methods, the output busbars 300 and DC contactors 200 can be more efficiently arranged within a limited space, reducing the equipment footprint.

[0070] like Figure 4 As shown, Figure 4 This is a top view of a multi-channel matrix power distribution device in an embodiment of the present application.

[0071] In some embodiments of the present application, the number of the output copper busbars 300 is 6, and the number of the DC contactors 200 is 15.

[0072] In this embodiment, the device includes six output copper bars 300 and fifteen DC contactors 200, so that each DC contactor 200 is connected to two different output copper bars 300, and a DC contactor 200 is provided between any two output copper bars 300.

[0073] like Figure 4 As shown, the six output copper bars 300 include a first output copper bar 301, a second output copper bar 302, a third output copper bar 303, a fourth output copper bar 304, a fifth output copper bar 305 and a sixth output copper bar 306, and flexible combination and common path control between the output ports are achieved through DC contactors.

[0074] The first output copper bar 301 and the second output copper bar 302 are connected in common via a DC contactor 212, the first output copper bar 301 and the third output copper bar 303 are connected in common via a DC contactor 213, the first output copper bar 301 and the fourth output copper bar 304 are connected in common via a DC contactor 214, the first output copper bar 301 and the fifth output copper bar 305 are connected in common via a DC contactor 215, and the first output copper bar 301 and the sixth output copper bar 306 are connected in common via a DC contactor 216.

[0075] The second output copper bar 302 and the third output copper bar 303 are controlled to share a common path through the DC contactor 223, the second output copper bar 302 and the fourth output copper bar 304 are controlled to share a common path through the DC contactor 224, the second output copper bar 302 and the fifth output copper bar 305 are controlled to share a common path through the DC contactor 225, and the second output copper bar 302 and the sixth output copper bar 306 are controlled to share a common path through the DC contactor 226.

[0076] The third output copper bar 303 and the fourth output copper bar 304 are controlled to share a common path through the DC contactor 234, the third output copper bar 303 and the fifth output copper bar 305 are controlled to share a common path through the DC contactor 235, and the third output copper bar 303 and the sixth output copper bar 306 are controlled to share a common path through the DC contactor 236.

[0077] The fourth output copper bar 304 and the fifth output copper bar 305 are connected in common via a DC contactor 245 , and the fourth output copper bar 304 and the sixth output copper bar 306 are connected in common via a DC contactor 246 .

[0078] The fifth output copper busbar 305 and the sixth output copper busbar 306 are connected in common via a DC contactor 256 .

[0079] This design allows each output port to be flexibly combined according to actual needs, providing different power output combinations, greatly improving the adaptability and flexibility of the charging pile.

[0080] In this embodiment, multiple connection methods provide high redundancy. This means that even if one output copper busbar 300 fails, the system can continue to operate by connecting to another output copper busbar 300, thereby improving system reliability. Combined with an intelligent management system, when multiple electric vehicles are charging simultaneously, the power distribution of each output can be dynamically adjusted according to the charging needs of each electric vehicle, achieving efficient distribution of limited charging power, improving overall charging efficiency, and reducing charging time.
