Detailed implementation manners

[0051] The following details the implementation manners of the present application. The examples of the implementation manners are shown in the drawings, where the same or similar reference numerals always denote the same or similar elements or elements with the same or similar functions. The implementation manners described below with reference to the drawings are exemplary only for explaining the present application and should not be construed as limiting the present application.

[0052] Please refer to Figure 4 and Figure 7 , the implementation manner of the present application provides a charging device 100. The charging device 100 includes a first circuit 101 and a second circuit 102. The first circuit 101 includes an input end and an output end, and the output end of the first circuit 101 is used to output a positive signal. The second circuit 102 includes an input end and an output end, and the output end of the second circuit 102 is used to output a negative signal. The first circuit 101 and the second circuit 102 are separately arranged.

[0053] In the charging device 100 according to the embodiments of the present application, the first circuit 101 and the second circuit 102 are separately arranged. In this way, isolation of the positive and negative electrodes is achieved, which can reduce the safety risks caused by misoperation or short circuit, and reduce the complexity and time cost of maintenance and repair.

[0054] Specifically, the first circuit 101 includes an input end and an output end. The input end receives a positive electrode signal and then outputs it from the output end. The second circuit 102 also includes an input end and an output end. The input end receives a negative electrode signal and then outputs it from the output end. The first circuit 101 and the second circuit 102 are separately arranged and combined to form the charging device 100, and isolation of the positive and negative electrodes is achieved in the charging device 100, which can reduce the safety risks caused by misoperation or short circuit.

[0055] During daily maintenance, the first circuit 101 and the second circuit 102 can be maintained separately, reducing the complexity of maintenance; and when one of the first circuit and the second circuit fails, the corresponding circuit can be repaired separately, reducing the complexity and time cost of repair.

[0056] Please refer to Figure 4 and Figure 7 , in some embodiments, the first circuit 101 and the second circuit 102 have the same structure.

[0057] Specifically, the first circuit 101 and the second circuit 102 adopt the same components and have the same structure. Therefore, in the actual production process, there is no need to distinguish between the first circuit 101 and the second circuit 102, and only one type of circuit needs to be produced, which is beneficial to improving production efficiency.

[0058] Please refer to Figures 1 to 6 , in some embodiments, the charging device 100 further includes a first carrier 10 and a second carrier 20. The first carrier 10 is used to arrange one of the first circuit 101 and the second circuit 102, and the second carrier 20 is used to arrange the other of the first circuit 101 and the second circuit 102.

[0059] Specifically, the first carrier 10 and the second carrier 20 have the same structure. In one example, the first carrier 10 and the second carrier 20 can be a box body. The first carrier 10 is used to arrange one of the first circuit 101 and the second circuit 102, and the second carrier 20 is used to arrange the other of the first circuit 101 and the second circuit 102. For example, the first carrier 10 can be used to arrange the first circuit 101. At this time, the second carrier 20 is used to arrange the second circuit 102; the first carrier 10 can also be used to arrange the second circuit 102. At this time, the second carrier 20 is used to arrange the first circuit 101. The following will be described in detail with the first circuit 101 arranged in the first carrier 10 and the second circuit 102 arranged in the second carrier 20.

[0060] It should be noted that since the structures of the first circuit 101 and the second circuit 102 are the same, and the structures of the first carrier 10 and the second carrier 20 are also the same, in the actual production process, there is no need to distinguish between the first carrier 10 and the second carrier 20, as well as the first circuit 101 and the second circuit 102 provided therein. Only one type of carrier needs to be produced, and one type of circuit can be provided in the carrier, which is beneficial to improving production efficiency.

[0061] Please refer to Figures 1 to 6 , the first circuit 101 and / or the second circuit 102 includes at least two main copper bars 30, at least one distribution copper bar 40, and at least one DC contactor 50. The at least two main copper bars 30 are arranged side by side at intervals. A DC contactor 50 is provided between the two main copper bars 30. Both ends of the DC contactor 50 are electrically connected to the two main copper bars 30 through the distribution copper bar 40 respectively.

[0062] In the embodiment of the present application, the charging device 100 can be a distribution device that provides DC power for multiple devices, which can scientifically and reasonably distribute electric energy, ensure that the power output by each branch can meet the device requirements, and at the same time reduce the risk of line short circuit. The charging device 100 can be applied to the charging device 1000.

[0063] In any one of the first circuit 101 and the second circuit 102, a plurality of main copper bars 30, a plurality of distribution copper bars 40, and a plurality of DC contactors 50 are provided. The lengths of the plurality of main copper bars 30 are the same. The plurality of main copper bars 30 are used to transmit and output power to achieve multi-channel output of the main power supply. The plurality of main copper bars 30 are sequentially connected through the plurality of DC contactors 50 and the plurality of distribution copper bars 40, so that the power transmitted by one main copper bar 30 can be transmitted to any other main copper bar 30 through the DC contactor 50 and the distribution copper bar 40. At least some of the lengths of the plurality of distribution copper bars 40 are different to realize the connection between the plurality of main copper bars 30 at different distances.

[0064] The plurality of main copper bars 30 are arranged at intervals, and the plurality of DC contactors 50 are provided between the plurality of main copper bars 30. Both ends of each DC contactor 50 are respectively and correspondingly electrically connected to the two main copper bars 30 through the distribution copper bar 40. The connection between every two main copper bars 30 can be realized through at most two DC contactors 50. By controlling the on-off of one DC contactor 50, the on-off between the corresponding two main copper bars 30 can be controlled. Thus, by controlling the on-off of the plurality of DC contactors 50, the on-off between the plurality of main copper bars 30 can be controlled.

[0065] In one example, the number of main copper bars 30 in each carrier is 8, and the number of DC contactors 50 is 16. Please refer to Figures 6 to 8 According to Figure 7The circuit schematic diagram shown connects multiple main busbars 30 through a plurality of distribution busbars 40 and a plurality of DC contactors 50 within the first carrier 10 and the second carrier 20 respectively, resulting in the structure as shown in Figure 6 shown.

[0066] In the related art, cables are used to connect the main busbar 30 and the DC contactor 50. The current-carrying capacity of the cable is affected by various factors such as its cross-sectional area, material, and insulation layer, resulting in limitations on the power output of each path of the main busbar 30. Moreover, in a limited space, the cables may occupy more space due to their large quantity and complex routing. In addition, the cables may be affected by environmental factors (such as temperature, humidity, vibration, etc.) during long-term use, leading to problems such as insulation layer aging and joint loosening, thereby affecting their reliability.

[0067] In the embodiments of the present application, distribution busbars 40 are used to replace the cables to connect multiple main busbars 30 and DC contactors 50. The current-carrying capacities of the distribution busbars 40 and the main busbars 30 can be accurately determined. Moreover, when the charging device 100 is applied to charging devices 1000 with different powers, the sizes (such as cross-sections) of the distribution busbars 40 and the main busbars 30 can be adjusted accordingly to adjust the current-carrying capacity. In this way, the power output of each path of the main busbar 30 is not limited, and it can be applicable to charging devices 1000 with different powers. In addition, compared with the cables, the distribution busbars 40 have a compact structure and are convenient for layout, and can more effectively utilize space resources. Moreover, the distribution busbars 40 also have higher reliability and stability.

[0068] Please refer to Figure 1 and Figure 4 , in some embodiments, the first carrier 10 and the second carrier 20 are arranged in layers along the first direction.

[0069] Specifically, along the first direction (such as the Z-axis direction in Figure 1 ), the first carrier 10 and the second carrier 20 are arranged in layers. For example, along the first direction, the first carrier 10 is arranged on the first layer, and the second carrier 20 is arranged on the second layer. Of course, in other embodiments, the second carrier 20 may be arranged on the first layer, and the first carrier 10 may be arranged on the second layer. In this way, the DC positive pole and the DC negative pole are effectively isolated in space, reducing the risk of electrical accidents caused by short circuits or misoperations.

[0070] Please refer to Figure 1 and Figure 6 , in some embodiments, in the first circuit 101 and / or the second circuit 102, the arrangement manners of at least two main busbars 30, at least one distribution busbar 40, and at least one DC contactor 50 are the same.

[0071] Specifically, the arrangement manners of the multiple main busbars 30, the multiple distribution busbars 40, and the multiple DC contactors 50 are the same. That is to say, the multiple main busbars 30 in the first circuit 101 and the multiple main busbars 30 in the second circuit 102 are arranged at intervals in the same manner; the multiple DC contactors 50 in the first circuit 101 and the multiple DC contactors 50 in the second circuit 102 are correspondingly arranged between the multiple main busbars 30 in the same manner; the multiple distribution busbars 40 in the first circuit 101 and the multiple distribution busbars 40 in the second circuit 102 are arranged in the same manner and are correspondingly connected to the multiple main busbars 30 and the multiple DC contactors 50.

[0072] Figure 8 Taking the output end as an example, for the arrangement manners of the multiple main busbars 30, the multiple distribution busbars 40, and the multiple DC contactors 50 in the first circuit 101, from right to left, the 8 main busbars 30 are successively DC01+, DC05+, DC02+, DC06+, DC03+, DC07+, DC04+ and DC08+, corresponding to Figure 7 the 8 main busbars 30 from top to bottom in it.

[0073] Then, in the second circuit 102, still taking the output end as an example, from right to left, the 8 main busbars 30 are successively DC01-, DC05-, DC02-, DC06-, DC03-, DC07-, DC04- and DC08-, corresponding to Figure 7 the 8 main busbars 30 from top to bottom in it.

[0074] Please refer to Figure 1 and Figure 6 , in some embodiments, in the first circuit 101 and / or the second circuit 102, at least two main busbars 30 are arranged on the first layer, at least one distribution busbar 40 is arranged on the second layer, and the first layer and the second layer are arranged along the first direction.

[0075] Specifically, in each carrier, along the first direction, multiple distribution busbars 40 can be arranged on the first layer, and multiple main busbars 30 are arranged on the second layer. Of course, in other embodiments, multiple main busbars 30 can be arranged on the first layer, and multiple distribution busbars 40 are arranged on the second layer.

[0076] It should be noted that, in order to ensure the safe operation of the charging device 1000 and prevent problems such as arc flashovers, the arrangement of the copper bars needs to meet certain electrical clearance requirements. In the embodiments of the present application, the layered arrangement of the plurality of main copper bars 30 and the plurality of distribution copper bars 40 in the first direction can meet the electrical clearance requirements, ensuring that the charging device 1000 will not experience arc discharge or breakdown phenomena under normal operating conditions, and guaranteeing the safe operation of the charging device 1000; at the same time, it is also beneficial for heat dissipation and maintenance, improving the overall performance of the charging device 1000. In addition, it is also convenient for the plurality of distribution copper bars 40 to bridge the main copper bars 30 at different distances.

[0077] Please refer to Figure 1 and Figure 6 , in some embodiments, in the first circuit 101 and / or the second circuit 102, each main copper bar 30 includes a first end 31 and a second end 32 that are opposite to each other in the second direction. The first end 31 is located on the side where the input terminal is located, and the second end 32 is located on the side where the output terminal is located. At least two first ends 31 corresponding to at least two main copper bars are all used for inputting power. At least one DC contactor 50 is used to control the on / off between at least two main copper bars 30, so that at least one of the at least two second ends 32 corresponding to the at least two main copper bars 30 outputs power.

[0078] Specifically, in the first circuit 101, each main copper bar 30 includes a first end 31 and a second end 32 that are opposite to each other in the second direction (such as Figure 1 the X-axis direction in

[0079] For example, please combine Figure 8 and Figure 9, the main copper busbar DC08+ can be connected to the main copper busbar DC01+ through DC contactors S28+, S12+ and multiple distribution copper busbars 40, and the input power of the main copper busbar DC08+ can be transmitted to the main copper busbar DC01+. In a similar manner, the main copper busbars DC04+, DC07+, DC03+, DC06+, DC02+ and DC05+ can all be connected to the main copper busbar DC01+, and the input power of the main copper busbars DC04+, DC07+, DC03+, DC06+, DC02+ and DC05+ can all be transmitted to the main copper busbar DC01+, and the output power is only output from the main copper busbar DC01+ in one path.

[0080] Similarly, in the second circuit 102, each main copper busbar 30 also includes a first end 31 and a second end 32 opposite to each other along the second direction (such as Figure 1 the X-axis direction in the figure). Any one or more of the multiple main copper busbars 30 can be used as the negative copper busbar for outputting power. That is to say, the input power of the multiple main copper busbars 30 can all be transmitted to the second end 32 of any one main copper busbar 30 for output, or can be transmitted to the second ends 32 of 2, 3 or more main copper busbars 30 for output. Of course, all the multiple main copper busbars 30 can also be used as the negative copper busbars for outputting power. In this way, flexible scheduling between multiple output powers can be achieved to realize power outputs of different sizes.

[0081] Please refer to Figures 4 to 6 , Figure 10 , in some embodiments, the first carrier 10 includes a first bottom plate 11. Inside the first carrier 10, at least two main copper busbars 30 and at least one DC contactor 50 are fixed to the first bottom plate 11 through a first fixing member 12. The second carrier 20 includes a second bottom plate 21. Inside the second carrier 20, at least two main copper busbars 30 and at least one DC contactor 50 are fixed to the second bottom plate 21 through a second fixing member 22. The first fixing member 12 includes bolts and / or nuts, and the second fixing member 22 includes bolts and / or nuts.

[0082] Specifically, the first carrier 10 includes a first bottom plate 11. Inside the first carrier 10, multiple main copper busbars 30 and multiple DC contactors 50 are fixed to the first bottom plate 11 through a first fixing member 12, and the multiple main copper busbars 30 and the multiple DC contactors 50 are detachably connected to the first bottom plate 11. The second carrier 20 includes a second bottom plate 21. Inside the second carrier 20, multiple main copper busbars 30 and multiple DC contactors 50 are fixed to the second bottom plate 21 through a second fixing member 22, and the multiple main copper busbars 30 and the multiple DC contactors 50 are detachably connected to the second bottom plate 21. In this way, when the main copper busbar 30 and the DC contactor 50 fail, it is convenient to replace a single component.

[0083] There is no limit on the number of the first fixing members 12 and the second fixing members 22. For example, Figure 5 as shown, in the first carrier 10, each main copper busbar 30 and each DC contactor 50 are fixed to the first base plate 11 by two first fixing members 12; of course, each main copper busbar 30 and each DC contactor 50 can also be fixed to the first base plate 11 by more first fixing members 12. For example, Figure 10 as shown, in the second carrier 20, each main copper busbar 30 and each DC contactor 50 are fixed to the second base plate 21 by two second fixing members 22; of course, each main copper busbar 30 and each DC contactor 50 can also be fixed to the second base plate 21 by more second fixing members 22.

[0084] The first fixing members 12 and the second fixing members 22 can be bolts or nuts, or include bolts and nuts at the same time. In one example, the first fixing member 12 includes a bolt and a nut. Specifically, the nut can be a press riveting nut. The nut is arranged on the first base plate 11. By cooperating with the bolt, a plurality of main copper busbars 30 and a plurality of DC contactors 50 can be fixed to the first base plate 11. The second fixing member 22 also includes a bolt and a nut. Specifically, the nut can be a press riveting nut. The nut is arranged on the second base plate. By cooperating with the bolt, a plurality of main copper busbars 30 and a plurality of DC contactors 50 can be fixed to the second base plate 21.

[0085] In some embodiments, a plurality of distribution copper busbars 40 are connected to a plurality of main copper busbars 30 and a plurality of DC contactors 50 by a fifth fixing member 25. The fifth fixing member 25 includes a bolt and / or a nut.

[0086] Please refer to Figure 4 、 Figure 5 and Figure 12 . In some embodiments, the first base plate 11 is detachably connected to the cabinet body 200 of the charging device 1000 by a third fixing member 13. The third fixing member 13 is also used to space the first base plate 11 from the cabinet body 200. The third fixing member 13 includes a bolt and / or a nut.

[0087] Specifically, the charging device 1000 includes a cabinet body 200. The charging device 100 can be arranged in the cabinet body 200. The first base plate 11 is detachably connected to the cabinet body 200 of the charging main body by a third fixing member 13, so that the charging device 100 is detachably connected to the cabinet body 200. In this way, when the charging device 100 fails, the charging device 100 can be detached from the charging device 1000 as a whole, which is convenient for maintenance or replacement of the charging device 100.

[0088] The third fixing member 13 has a certain thickness. The third fixing member 13 is partially located between the first bottom plate 11 and the cabinet body 200, so that the first bottom plate 11 and the cabinet body 200 are spaced apart. The third fixing member 13 can be a bolt or a nut, or include both a bolt and a nut. In one example, the third fixing member 13 includes a bolt and a nut. Specifically, the nut can be a press riveting nut. The nut is arranged between the first bottom plate 11 and the cabinet body 200. By cooperating with the bolt, the first bottom plate 11 and the cabinet body 200 are detachably connected.

[0089] There is no limit to the number of the third fixing members 13. In one example, as Figure 5 shown, at the upper part of the first bottom plate 11, it is connected to the cabinet body 200 through 3 third fixing members 13; at the middle part of the first bottom plate 11, it is connected to the cabinet body 200 through 4 third fixing members 13; at the lower part of the first bottom plate 11, it is connected to the cabinet body 200 through 3 third fixing members 13.

[0090] It should be noted that along the direction extending from the first bottom plate 11 to the cabinet body 200, the thickness of the third fixing member 13 is greater than or equal to the thickness of the first fixing member 12, so as to ensure that the first fixing member 12 does not interfere with the connection between the first bottom plate 11 and the cabinet body 200.

[0091] Please refer to Figure 4 and Figure 10 , in some embodiments, the second bottom plate 21 is detachably connected to the side of the first carrier 10 away from the first bottom plate 11 through a fourth fixing member 23. The fourth fixing member 23 includes a bolt and / or a nut.

[0092] Specifically, the fourth fixing member 23 can be a bolt or a nut, or include both a bolt and a nut. For example, the fourth fixing member 23 includes a bolt and a nut. Through the cooperation between the bolt and the nut, the second bottom plate 21 is detachably connected to the side of the first carrier 10 away from the first bottom plate 11. In this way, the second carrier 20 can be detached from the first carrier 10 as a whole. When the first carrier 10 fails, the second carrier 20 is detached from the charging device 100, which is convenient for overhauling or replacing components inside the first carrier 10. When the second carrier 20 fails, the entire second carrier 20 can be replaced if necessary.

[0093] There is no limit to the number of the fourth fixing members 23. In one example, as Figure 10 shown, one side of the second bottom plate 21 along the third direction (such as the Y-axis direction in Figure 1 ) is connected to the first carrier 10 through 3 fourth fixing members 23, and the other side is also connected to the first carrier 10 through 3 fourth fixing members 23.

[0094] Please refer to Figure 1 and Figure 6, in some embodiments, the first circuit 101 and / or the second circuit 102 further includes at least two infeeders 61 and at least two outfeeders 62. Each main busbar 30 includes a first end 31 and a second end 32 that are opposite to each other in the second direction.

One end of each outfeeder is connected to the second end 32 of a main busbar 30, and the other end of each outfeeder 62 is used to connect to the charging terminal.

[0095] Specifically, both the first circuit 101 and the second circuit 102 are provided with a plurality of infeeders 61 and a plurality of outfeeders 62. The infeeders 61 are used to connect to the rectifier module 400 of the charging device 1000 through bolts and / or nuts, etc., so as to connect the rectifier module 400 to the charging device 100, enabling the rectifier module 400 to provide input power for the charging device 100. The outfeeders 62 are used to connect to the charging terminal (such as an electric vehicle) through cables, etc., so as to transmit the output power of the charging device 100 to the charging terminal for charging the charging terminal.

[0096] The number of infeeders 61 and outfeeders 62 is the same as the number of main busbars 30. Taking the number of main busbars 30 in each carrier as 8 as an example, in each carrier, the number of infeeders 61 is 8, and the number of outfeeders 62 is also 8.

[0097] The plurality of main busbars 30 are arranged in the third direction and extend in the second direction. Each main busbar 30 includes a first end 31 and a second end 32 that are opposite to each other in the second direction. The first end 31 is located on the side where the input terminal of the corresponding circuit is located, and the second end 32 is located on the side where the output terminal of the corresponding circuit is located. The plurality of infeeders 61 are also arranged in the third direction and are respectively connected to the first ends 31 of the plurality of main busbars 30. The plurality of outfeeders 62 are also arranged in the third direction and are respectively connected to the second ends 32 of the plurality of main busbars 30.

[0099] Specifically, each incoming wire connector 61 includes a plurality of holes, and each hole can be connected to the rectification module 400 through bolts and / or nuts, etc. Each incoming wire connector 61 can be connected to a plurality of rectification modules 400 through a plurality of holes, so that each main copper busbar 30 can be connected to a plurality of rectification modules 400. As Figure 6 shown, each incoming wire connector 61 includes 2 holes, and 8 incoming wire connectors 61 include a total of 16 holes, which can be respectively connected to 16 rectification modules 400.

[0100] Combined with Figure 6 and Figure 7 , the main copper busbar DC01+ can be connected to the rectification modules PM1 and PM2; the main copper busbar DC05+ can be connected to the rectification modules PM3 and PM4; the main copper busbar DC02+ can be connected to the rectification modules PM5 and PM6; the main copper busbar DC06+ can be connected to the rectification modules PM7 and PM8; the main copper busbar DC03+ can be connected to the rectification modules PM9 and PM10; the main copper busbar DC07+ can be connected to the rectification modules PM11 and PM12; the main copper busbar DC04+ can be connected to the rectification modules PM13 and PM14; the main copper busbar DC08+ can be connected to the rectification modules PM15 and PM16.

[0101] Assume that the power of 16 rectification modules 400 is 40kW each, then the total input power is 640kW. According to the above connection method, when 8 main copper busbars 30 all output power as positive copper busbars, the output power of each main copper busbar 30 is 80kW. If only one main copper busbar 30 outputs power as a positive copper busbar, the output power of this main copper busbar 30 is 640kW.

[0102] The multiple holes of each incoming wire connector 61 are arranged in a staggered manner along the first direction; or, along the second direction; or, along both the first direction and the second direction. In this way, sufficient space is reserved between the multiple holes of the same connector 61, which is convenient for wiring.

[0106] Specifically, each DC contactor 50 is connected with a control cable. The other end of the control cable is connected to the controller 300 of the charging device 1000. Thus, the on-off of multiple DC contactors 50 can be controlled through the controller 300, and further the on-off between multiple main copper bars 30 can be controlled.

[0107] Each carrier includes two side plates 70 opposite to each other in the third direction. Each side plate 70 is provided with a plurality of wire outlets 71. The number of wire outlets 71 is not limited. For example, the number of wire outlets 71 can be 1, 2, 3 or more. As Figure 4 shown, each side plate 70 is provided with 2 wire outlets 71. One end of the control cable is connected to the DC contactor 50, and the other end runs to the outside of the carrier from any one of the multiple wire outlets 71 to be connected to the controller 300.

The first carrier 10 is detachably connected to the second carrier 20 through the two thickened edges 72.

[0109] Specifically, the two side plates 70 of the first carrier 10 include two ends opposite to each other in the first height direction. One end is connected to the first base plate 11, and the other end is close to the second carrier 20. One end of the side plate 70 close to the second carrier 20 is folded towards the inside of the first carrier 10 to form two thickened edges 72. The folding angle can be 90° - 180°. For example, one end of the side plate 70 close to the second carrier 20 can be folded towards the inside of the first carrier 10 at 90°, 100°, 110°, 120°, 130°, 140°, 150°, 160°, 170°, 180° or any angle within 90° - 180°.

[0110] The first carrier 10 is detachably connected to the second carrier 20 through two thickened edges 72. In this way, compared with connecting to the second carrier 20 through one end of the side plate 70, the strength of the charging device 100 can be enhanced, the side plate 70 can be prevented from being torn, and the stability and reliability of the charging device 100 can be improved.

[0117] The control cable connected to the DC contactor 50 passes through the arched portion 80, is fixed to the first bottom plate 11 or the second bottom plate 21 by the arched portion 80, and then routes to the outlet 71 and out of the carrier. In this way, the neatness of the control cable routing in the first carrier 10 and the second carrier 20 can be improved, and the movement and vibration of the control cable during the operation of the charging device 1000 can be effectively reduced, avoiding the disconnection of the control cable from the DC contact 50.
