Description
Technical Field
[0001] This utility model relates to the field of automotive charging technology, specifically to an arrangement structure, a charging cabinet, and a charging system. Background Technology
[0002] A four-gun DC power adapter is a charging device equipped with four charging guns. Compared to the traditional dual-gun DC power adapter, the four-gun DC power adapter not only has more charging guns, but also allows for power distribution among its multiple internal power modules, thus meeting flexible and high-power charging needs.
[0003] like Figure 1-2 As shown, the existing four-gun DC integrated machine has the following problems: Low power allocation flexibility: The existing four-gun DC integrated machine adopts a ring power allocation scheme in the form of DC relays. Each charging gun can only call the adjacent power modules in sequence through the DC relays, and cannot directly call any power module. The power allocation flexibility is still low.
[0004] Large size and large space occupation: Existing four-gun DC integrated machines install DC relays, copper busbars, and other components on mounting plate 1', such as... Figure 1 As shown, the positive output terminal 2' and negative output terminal 3' of the first charging gun are located on the left side of the front of the mounting plate 1', and the positive output terminal 2' and negative output terminal 3' of the second charging gun are located on the right side of the front of the mounting plate 1'; Figure 2 As shown, the positive output terminal 2' and negative output terminal 3' of the third charging gun are located on the left side of the back of the mounting plate 1', and the positive output terminal 2' and negative output terminal 3' of the fourth charging gun are located on the right side of the back of the mounting plate 1'. Four positive DC relays 4' are arranged in a front-to-back arrangement with positive copper busbars 6', and four negative DC relays 5' are also arranged in a front-to-back arrangement with negative copper busbars 6'. This arrangement results in a large pile size and a large space occupation, making it unsuitable for parking lots with limited space. Moreover, it requires doors to be designed at both the front and back of the pile. In some scenarios, such as when the charging pile needs to be placed against a wall to save space, it has significant limitations.
[0005] The charging site has high requirements: the existing four-gun DC integrated charging station needs to be set in the middle of four parking spaces arranged in a square array so that the charging line can meet the charging needs of these four parking spaces; however, if the parking spaces are arranged in a straight line, some parking spaces will be far away from the four-gun DC integrated charging station, and the charging gun line has a limited length, which cannot meet the charging needs of some vehicles.

[0024] Example 1:
[0025] like Figure 3-4As shown, this embodiment provides a power distribution arrangement structure that can be used in a charging cabinet 100. The arrangement structure includes a mounting plate 1, a positive power distribution component 2, and a negative power distribution component 3. The positive power distribution component 2 and the negative power distribution component 3 are both arranged on the same side of the mounting plate 1, for example, the front side.
[0026] Furthermore, the positive power distribution assembly 2 includes multiple positive power distribution conductive buses 21 and several positive power distribution relays 22 for power distribution. The positive power distribution conductive buses 21 and positive power distribution relays 22 are arranged according to a set power distribution topology, such as a ring power distribution topology or a full matrix power distribution topology. The positive power distribution relays 22 are mounted on the mounting plate 1, and the positive power distribution conductive buses 21 are mounted on the positive power distribution relays 22. Insulators 11 can be provided for auxiliary support if necessary. The positive power distribution conductive buses 21 can be, but are not limited to, copper or aluminum buses.
[0027] Similarly, the negative power distribution assembly 3 includes multiple negative power distribution conductive buses 31 and several negative power distribution relays 32 for power distribution. The negative power distribution conductive buses 31 and negative power distribution relays 32 are arranged according to the same power distribution topology, such as a ring power distribution topology or a full matrix power distribution topology. The negative power distribution relays 32 are mounted on the mounting plate 1, and the negative power distribution conductive buses 31 are mounted on the negative power distribution relays 32. Insulators 11 can be provided for auxiliary support if necessary. The negative power distribution conductive buses 31 can be, but are not limited to, copper or aluminum buses.
[0028] Thus, compared with the prior art, the arrangement structure of this embodiment installs the positive power distribution component 2 and the negative power distribution component 3 on the same side of the mounting plate 1, such as the front side. The positive power distribution relay 22, the positive power distribution busbar 21, the negative power distribution relay 32, and the negative power distribution busbar 31 are all arranged on the front side of the mounting plate 1, making full use of the front space. No components are set on the back side of the mounting plate 1, thereby reducing the overall thickness and volume. The volume of the cabinet using this arrangement structure is reduced, and it can be reduced to 58% of the existing technical solution. Moreover, the cabinet can be placed against the wall to save space.
[0029] The power distribution topology can be a ring power distribution topology.
[0030] Specifically, the positive power distribution bus 21 includes a positive ring-connected bus 211, and the positive power distribution relay 22 includes a positive ring-connected relay 221. The positive ring-connected bus 211 and the positive ring-connected relay 221 are arranged sequentially at intervals to form a positive ring electrical connection structure. Each positive ring-connected bus 211 is electrically connected to the positive terminal of a power module group, and a power module group may include one or more power modules connected in parallel.
[0031] Similarly, the negative power distribution bus 31 includes a negative ring bus 311, and the negative power distribution relay 32 includes a negative ring relay 321. The negative ring bus 311 and the negative ring relay 321 are arranged sequentially at intervals to form a negative ring electrical connection structure. Each negative ring bus 311 is electrically connected to the negative terminal of a power module group, and a power module group may include one or more power modules connected in parallel.
[0032] In this way, each positive-pole ring-connected busbar 211 and negative-pole ring-connected busbar 311 can not only call the power module group directly connected to it, but also sequentially call the adjacent power module group along the ring power distribution topology.
[0033] Preferably, the power distribution topology in this embodiment is further improved based on the above-mentioned ring power distribution topology to form a full matrix power distribution topology, which further enhances flexibility.
[0034] Specifically, the positive power distribution bus 21 further includes a positive bridging bus 212, and the positive power distribution relay 22 further includes a positive bridging relay 222. The positive bridging bus 212 and the positive bridging relay 222 cooperate to electrically connect every two non-adjacent positive ring-shaped bus 211 in the aforementioned positive ring-shaped electrical connection structure.
[0035] Similarly, the negative power distribution bus 31 also includes a negative bridging bus 312, and the negative power distribution relay 32 also includes a negative bridging relay 322. The negative bridging bus 312 and the negative bridging relay 322 cooperate to electrically connect every two non-adjacent negative ring-shaped bus 311 in the aforementioned negative ring-shaped electrical connection structure.
[0036] In this way, each positive terminal ring bus 211 and negative terminal ring bus 311 can directly call any power module group, making power distribution more flexible.
[0037] Figure 7A schematic diagram of a full matrix power distribution topology including four power module groups is provided as an example. Specifically, each power module group includes a 40KW power module, namely power modules M1 to M4. The positive and negative terminals of power modules M1 and M2 are electrically connected via relays KM1 and KM2, respectively; the positive and negative terminals of power modules M2 and M3 are electrically connected via relays KM3 and KM4, respectively; the positive and negative terminals of power modules M3 and M4 are electrically connected via relays KM5 and KM6, respectively; the positive and negative terminals of power modules M4 and M1 are electrically connected via relays KM7 and KM8, respectively; the positive and negative terminals of power modules M1 and M3 are electrically connected via relays KM9 and KM10, respectively; and the positive and negative terminals of power modules M2 and M4 are electrically connected via relays KM11 and KM12, respectively. Each power module's directly connected DC output terminal, such as 1#DC+ and 1#DC-, or 2#DC+ and 2#DC-, or 3#DC+ and 3#DC-, or 4#DC+ and 4#DC-, can call any of the other power modules.
[0038] Referring to this full matrix power allocation topology, such as Figure 3-4 As shown, the positive power distribution busbar 21 in this embodiment includes four positive ring busbars 211 and four positive bridging busbars 212, and the positive power distribution relay 22 includes four positive ring relays 221 and two positive bridging relays 222. The four positive ring busbars 211 and the four positive ring relays 221 enclose a positive square frame structure 23, and the four positive bridging busbars 212 and the two positive bridging relays 222 are located inside the positive square frame structure 23. Since there is an intersection between two positive bridging busbars 212, in this embodiment, the intersection of one positive bridging busbar 212 and the other positive bridging busbar 212 is bent towards or away from the mounting plate 1 to avoid interference.
[0039] In this embodiment, each positive terminal ring busbar 211 is also provided with a positive terminal connection point 2111 connected to the positive terminal of the corresponding power module. In this embodiment, there are four positive terminal bridging busbars 212, that is, there are two positive terminal bridging busbars 212 for each positive terminal bridging relay 222, located at its two ends respectively; in other embodiments, two positive terminal bridging busbars 212 may also be provided, that is, only one positive terminal bridging busbar 212 is provided for each positive terminal bridging relay 222, located at one end, and its other end is directly installed on the corresponding positive terminal ring busbar 211.
[0040] Preferably, each positive electrode ring-connecting conductive bar 211 in this embodiment is an integral conductive bar; however, in other embodiments, multiple conductive bars can be overlapped. In this embodiment, the positive electrode bridging conductive bars 212 bent towards or away from the mounting plate 1 overlap with the corresponding positive electrode ring-connecting conductive bars 211, while the remaining positive electrode bridging conductive bars 212 are integrally formed with their corresponding positive electrode ring-connecting conductive bars 211. For example… Figure 3 The positive terminal bridging conductor 212 on the left side of the positive terminal bridging relay 222 is integrated with the positive terminal ring conductor 211 in the upper left corner. The positive terminal bridging conductor 212 on the right side of the positive terminal bridging relay 222 is integrated with the positive terminal ring conductor 211 in the lower right corner. The positive terminal bridging conductor 212 on the upper side of the positive terminal bridging relay 222 on the right side is integrated with the positive terminal ring conductor 211 in the upper right corner. The positive terminal bridging conductor 212 on the lower side of the positive terminal bridging relay 222 overlaps with the positive terminal ring conductor 211 in the lower left corner. This facilitates the manufacturing of each conductor.
[0041] Preferably, in this embodiment, the four positive loop relays 221 are located at the center of the four sides of the positive square structure 23; and the left and right ends of the two upper positive loop conductive buses 211 are respectively formed as their output terminals, and the left and right ends of the two lower positive loop conductive buses 211 are respectively formed as their output terminals. If each positive loop relay 221 is set at one of the four corners of the positive square structure 23, then the output terminals of the four positive loop conductive buses 211 need to be set in the four directions of up, down, left, and right. Therefore, compared with the previous embodiment, this embodiment is more convenient for the arrangement of the positive power distribution component 2 and the negative power distribution component 3, and can save space.
[0042] Similarly, refer to Figure 7 The full matrix power distribution topology shown in this embodiment includes four negative power distribution conductors 311 and four negative power bridging conductors 312, and four negative power distribution relays 32, which include four negative power distribution relays 321 and two negative power bridging relays 322. The four negative power distribution conductors 311 and four negative power distribution relays 321 enclose a negative square structure 33, and the four negative power bridging conductors 312 and two negative power bridging relays 322 are located inside the negative square structure 33. Since there is an intersection between two negative power bridging conductors 312, this embodiment sets the intersection of one negative power bridging conductor 312 with the other negative power bridging conductor 312 to be bent toward or away from the mounting plate 1 to avoid it.
[0043] In this embodiment, each negative terminal ring-connecting conductive bus 311 is also provided with a negative terminal connection point 3111 connected to the negative terminal of the corresponding power module. In this embodiment, there are four negative terminal bridging conductive buses 312, that is, there are two negative terminal bridging conductive buses 312 for each negative terminal bridging relay 322, located at its two ends respectively; in other embodiments, two negative terminal bridging conductive buses 312 may also be provided, that is, there is only one negative terminal bridging conductive bus 312 for each negative terminal bridging relay 322, located at one end, and its other end is directly installed on the corresponding negative terminal ring-connecting conductive bus 311.
[0044] Preferably, each negative electrode ring-connecting conductive bar 311 in this embodiment is preferably an integral conductive bar; however, in other embodiments, multiple conductive bars can be overlapped. In this embodiment, the negative electrode bridging conductive bars 312 that bend towards or away from the mounting plate 1 overlap with the corresponding negative electrode ring-connecting conductive bars 311, while the remaining negative electrode bridging conductive bars 312 are integrally formed with the corresponding negative electrode ring-connecting conductive bars 311. For example... Figure 3 The negative terminal bridging conductor 312 on the left side of the negative terminal bridging relay 322 located on the left is integrated with the negative terminal ring conductor 311 in the upper left corner. The negative terminal bridging conductor 312 on the right side of the negative terminal bridging relay 322 is integrated with the negative terminal ring conductor 311 in the lower right corner. The negative terminal bridging conductor 312 on the upper side of the negative terminal bridging relay 322 located on the right is integrated with the negative terminal ring conductor 311 in the upper right corner. The negative terminal bridging conductor 312 on the lower side of the negative terminal bridging relay 322 overlaps with the negative terminal ring conductor 311 in the lower left corner. This facilitates the processing and manufacturing of each conductor.
[0045] Preferably, in this embodiment, the four negative loop relays 321 are located at the middle of the four sides of the negative square structure 33; and the left and right ends of the two upper negative loop conductive buses 311 are respectively formed as their output terminals, and the left and right ends of the two lower negative loop conductive buses 311 are respectively formed as their output terminals. If each negative loop relay 321 is set at one of the four corners of the negative square structure 33, then the output terminals of the four negative loop conductive buses 311 need to be set in the four directions of up, down, left, and right. Therefore, compared with the previous embodiment, this embodiment is more convenient for the arrangement of the negative power distribution component 3 and the positive power distribution component 2, and can save space.
[0046] In this embodiment, the output terminals of a portion of the positive-pole ring-connected conductive bus 211 are also connected to a first positive-pole output conductive bus 42 and a first fuse 43 via a first positive-pole output relay 41; the output terminals of a portion of the negative-pole ring-connected conductive bus 311 are also connected to a first negative-pole output conductive bus 52 and a first shunt 53 via a first negative-pole output relay 51.
[0047] For example Figure 3 As shown, the left and right ends of the two upper positive output busbars 211 are connected in sequence to the first positive output relay 41, the first positive output busbar 42, the first fuse 43, and the first positive output busbar 42, which can be connected to the positive terminals of the two charging guns on the charging cabinet 100 respectively. The left and right ends of the two lower positive output busbars 211 can be used to connect to the second positive output busbar 62, the second positive output relay 61, and the second fuse 63 in the subsequent terminal 200 via cables. Similarly, the left and right ends of the two upper negative terminal ring-connected conductive bars 311 are respectively connected to the first negative terminal output relay 51, the first negative terminal output conductive bar 52, the first shunt 53, and the first negative terminal output conductive bar 52, which can be connected to the negative terminals of the two charging guns on the charging cabinet 100 respectively; while the left and right ends of the two lower negative terminal ring-connected conductive bars 311 can be used to connect to the second negative terminal output conductive bar 72, the second negative terminal output relay 71, and the second shunt 73 in the subsequent terminal 200 through the adapter conductive bar 54 and the cable.
[0048] Thus, the charging cabinet 100 in this embodiment can also be equipped with a terminal 200, forming a four-gun DC charging system of main cabinet + terminal 200. Compared with the four-gun DC integrated machine in the prior art, the charging cabinet 100 in this embodiment can be set in the first position of the charging site, while the terminal 200 can be set in a more distant second position, which makes it more convenient to charge vehicles in parking spaces that are far away. In addition, in this embodiment, other components such as the first fuse 43 and the first shunt 53 are also set on one side of the mounting plate 1, making full use of the space on one side of the mounting plate 1, resulting in a compact layout; the second fuse 63 and the second shunt 73 are set inside the terminal 200. Of course, in other embodiments, such as when all four charging guns are set on the charging cabinet 100, all fuses and shunts can also be set inside the charging cabinet 100.
[0049] Preferably, since the positive terminal bridging bus 212 and the negative terminal bridging bus 312 can carry the current of only one power module, the cross-sectional areas of the positive terminal bridging bus 212 and the negative terminal bridging bus 312 in this embodiment are smaller than the cross-sectional areas of the positive terminal ring bus 211, the negative terminal ring bus 311, the first positive terminal output bus 42, and the first negative terminal output bus 52. This allows for a more compact structural layout and reduces material costs. Of course, the current-carrying capacity of each relay and bus also needs to be considered when allocating power.
[0050] Similarly, since the positive jumper relay 222, negative jumper relay 322, positive loop relay 221, and negative loop relay 321 can each carry the current of only one power module, the rated current and size of the positive jumper relay 222, negative jumper relay 322, positive loop relay 221, and negative loop relay 321 in this embodiment are smaller than the rated current and size of the first positive output relay 41 and the first negative output relay 51. This also makes the structural layout more compact and reduces certain material costs.
[0051] Preferably, in this embodiment, the negative power distribution component 3 and the positive power distribution component 2 are arranged vertically, for example, the negative power distribution component 3 is arranged above the positive power distribution component 2, and the two are arranged independently in separate zones. In other embodiments, the positive power distribution component 2 and the negative power distribution component 3 can also adopt other arrangement methods, such as one arranged on the left and one on the right, or one in the inner ring and the other in the outer ring.
[0052] The mounting plate 1 has wire-passing grooves 12 located on the left side of the negative power distribution component 3 and on the left side of the positive power distribution component 2, respectively. The two wire-passing grooves 12 are used to introduce the negative and positive wires of each power module group. For convenient wiring and cable management, the mounting plate 1 also has several wire clips 13. A fan 14 is also provided in the lower right corner of the mounting plate 1 for heat dissipation. Of course, in other embodiments, the wire-passing grooves 12 can also be located on the right side of the negative power distribution component 3 and the positive power distribution component 2, respectively.
[0053] like Figure 3 As shown, the output ends of the two negative electrode ring-connected conductive bars 311 located below are also provided with transition conductive bars 54. The two transition conductive bars 54 are arranged vertically, and their ends are close to the output ends of the two positive electrode ring-connected conductive bars 211 below. The ends of the two transition conductive bars 54 and the output ends of the two positive electrode ring-connected conductive bars 211 below are used to connect to the terminal 200 through cables for easy operation. The transition conductive bars 54 need to be bent toward or away from the mounting plate 1 to avoid the first fuse 43.
[0054] The above provides an example implementation with four power module groups. When the number of power module groups is greater, this implementation can be followed, and will not be described in detail here.
[0055] As can be seen from the above, the arrangement structure provided in this embodiment places the positive power distribution component 2 and the negative power distribution component 3 on the same side of the mounting plate 1, which improves the space utilization rate. In addition, it also has the characteristics of low cost, convenient wiring, and aesthetics.
[0056] Example 2:
[0057] This embodiment provides a charging cabinet 100, which includes the arrangement structure described in Embodiment 1. The charging cabinet 100 can be the cabinet of an integrated charger or the main cabinet of a split charger.
[0058] Example 3:
[0059] This embodiment provides a charging system including a charging cabinet 100, which is the charging cabinet 100 described in Embodiment 1 or Embodiment 2, forming a main cabinet; the charging system also includes at least one terminal 200. The main cabinet is equipped with a motherboard, a power module, a positive power distribution component 2 and a negative power distribution component 3, as well as a charging control board, a meter, a screen, a shunt, a fuse, several charging guns, etc.; the terminal 200 is also equipped with a charging control board, a meter, a screen, a shunt, a fuse, several charging guns, etc.; both the main cabinet and the terminal 200 can perform human-machine interaction and charging. Even if any terminal 200 fails, the main cabinet can still output full power. The main cabinet and the terminal 200 communicate through a switch, and the main cabinet transmits the power-distributed current to the terminal 200. Thus, the terminal 200 can be configured at a location far from the main cabinet to meet the charging needs of vehicles in distant parking spaces. Take a four-gun DC charging system with one main cabinet and one 200V terminal as an example. Figure 6 As shown, the main cabinet includes two charging guns, namely gun #1 and gun #2; the terminal 200 includes two charging guns, namely gun #3 and gun #4. The main cabinet is equipped with power modules M1-M4, a power distribution component, and two first positive output relays 41, namely KM13 and KM15, and two first negative output relays 51, namely KM14 and KM16; the terminal 200 is equipped with two second positive output relays 61, namely KM17 and KM19, and two second negative output relays 71, namely KM18 and KM20.
[0060] like Figure 3-4As shown, a positive power distribution component 2 and a negative power distribution component 3 are configured inside the main cabinet. The negative power distribution component 3 is positioned above the mounting plate 1, and the positive power distribution component 2 is positioned below the mounting plate 1. In the negative power distribution component 3, the output terminals of the negative ring-connected conductive bus 311 at the upper left and upper right corners are sequentially connected to a first positive output relay 51, a first negative output conductive bus 52, a first shunt 53, and a first negative output conductive bus 52, and can also be electrically connected to the negative terminals of the two charging guns on the main cabinet. In the positive power distribution component 2, the output terminals of the positive ring-connected conductive bus 211 at the upper left and upper right corners are sequentially connected to a first positive output relay 41, a first positive output conductive bus 42, a first fuse 43, and a first positive output conductive bus 42, and can also be electrically connected to the positive terminals of the two charging guns on the main cabinet.
[0061] like Figure 5 As shown, the terminal 200 includes a second negative output relay 71, a second negative output conductive bus 72, and a second shunt 73. The output ends of the negative loop conductive bus 311 at the lower left and lower right corners of the main cabinet are connected to the terminal 200 via adapter conductive bus 54 and cables, respectively, and are sequentially connected to the second negative output conductive bus 72, the second negative output relay 71, and the second shunt 73. The upper ends can also be electrically connected to the negative terminals of the two charging guns on the terminal 200. The terminal 200 also includes a second positive output relay 61, a second positive output conductive bus 62, and a second fuse 63. The output ends of the positive loop conductive bus 211 at the lower left and lower right corners of the main cabinet are connected to the terminal 200 via cables, respectively, and are sequentially connected to the second positive output conductive bus 62, the second positive output relay 61, and the second fuse 63. The upper ends can also be electrically connected to the positive terminals of the two charging guns on the terminal 200.
[0062] The above provides an example of an implementation of one main cabinet + one terminal 200. In other embodiments, it can also be an implementation of one main cabinet + multiple terminals 200. The number of charging guns in the main cabinet and the terminal 200 can also be set as needed. The specific implementation can be referred to the above implementation, and will not be described in detail here.
[0063] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
