[0002] With the rapid development of the new energy vehicle industry, the proportion of charging piles as infrastructure construction is increasing, and the combination of various modular products is becoming more and more complex. For various types of single-pile and group charging products, the increase in modular products has made it normal to use the same product in different locations. Charging piles are often accompanied by multiple parallel modules working at the same time. Distinguishing different modules according to addresses has become an indispensable requirement for power allocation, on-site operation and maintenance. When setting the address of a modular product, the address can be set by different output energies of the modular product or in serial mode. When the product address is set by different output energies in the charging system, the charging connector output will be charged when not charging, posing a safety hazard; when the address is set in serial mode, the setting efficiency is low and the address cannot be set for parallel devices.

[0034] The core of the utility model is to provide an address configuration device and a group charging system including the address configuration device, which can improve the efficiency of address setting and improve the charging safety. After the product position is exchanged, the actual position will correspond to the new address, so that the operation and maintenance personnel can accurately locate the position of the modular product, thereby improving the maintenance efficiency.

[0035] In order to make the purpose, technical solution and advantages of the embodiment of the utility model clearer, the technical solution in the embodiment of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiment of the utility model. Obviously, the described embodiment is a part of the embodiment of the utility model, not all of the embodiments. Based on the embodiment of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0036] First, please refer to Figure 1 , Figure 1 This is a structural diagram of an address configuration device provided in the present application, the address configuration device comprising:

[0037] A setting circuit 11 is provided on a first device, the first device includes a first connection member, the setting circuit 11 includes a first common port and a plurality of first address ports, the first common port and the plurality of first address ports are both connected to the first connection member, and one or more first address ports are connected to the first common port, so as to configure an address configuration signal for the first connection member;

[0038] The detection circuit 12 is arranged on the second device, and the second device includes a second connector. When the second connector is connected to the first connector, the detection circuit 12 is triggered to obtain the address configuration signal and convert the address configuration signal into an address recognition signal and then output it.

[0039] Among them, the first device can be a backplane in a charging cabinet or a charging station, and the second device can be a charging module or a power distribution module or other modules that require clear address information in the charging system. The first device includes at least one first connector, and each first connector corresponds to a configuration circuit. The configuration circuit includes a first common port PORT C and multiple first address ports PORT 1~PORT n, where n is an integer greater than 1. It can be understood that in order to make different first connectors have independent address configuration signals, the number of first address ports connected to the first common port in the configuration circuits corresponding to the respective first connectors may be different. By way of example, it is assumed that the first device includes two first connectors, namely the first connector a and the first connector b, and the corresponding first device also includes two setting circuits 11, namely the setting circuit 11a connected to the first connector a and the setting circuit 11b connected to the first connector b. It is assumed that the setting circuit 11a and the setting circuit 11b each include four first address ports, namely PORT 1, PORT 2, PORT 3, and PORT 4. Then, in the setting circuit 11a, PORT 1 can be configured to be connected to PORT C, and in the setting circuit 11b, PORT 2 and PORT 3 can be configured to be connected to PORT C. The first address ports not connected to the first common port are set to be floating, thereby setting different address configuration signals for the first connector a and the first connector b.

[0040] It can be understood that the second device is provided with a second connector and a detection circuit 12. When the second connector is connected to the first connector, the detection circuit 12 and the configuration circuit are connected, thereby triggering the detection circuit 12 to obtain the connection relationship between each first address port and the first common port, thereby determining the address configuration signal configured by the configuration circuit for the first connector, and converting it into an address identification signal, so as to determine the address of the second device based on the address identification signal. It can be understood that the address of the second device is related to its location, and the address identification order will not be confused as the second device moves.

[0041] Among them, the connection methods between the detection circuit 12 and the configuration circuit include but are not limited to PCB gold finger connection, terminal plug-in, structural plug-in, optical coupling, magnetic coupling and other connection methods. The corresponding first connector and the second connector can be adaptively adjusted based on the selected connection method, and this embodiment does not make specific limitations here.

[0042] It can be seen that in this embodiment, the address configuration signal is configured for the first connector on the first device through the setting circuit 11 set on the first device, and the second device is provided with a detection circuit 12 and a second connector. When the first connector is connected to the second connector, the detection circuit 12 is connected to the setting circuit 11, so as to obtain the address configuration signal of the setting circuit 11, determine the address assigned to the first connector, and thus determine the position of the second device. Through hardware address setting and identification, the address setting efficiency is improved, and the charging safety is improved. After the product position is exchanged, the actual position will correspond to the new address, so that the operation and maintenance personnel can accurately locate and improve the maintenance efficiency.

[0043] Based on the above embodiments:

[0044] As an optional embodiment, refer to Figure 2 As shown, one or more first address ports are connected to the first common port via a connection line.

[0045] As an optional embodiment, refer to Figure 3 As shown, the setting circuit 11 also includes a switch arranged between each first address port and the first common port;

[0046] When the switch is turned on, the first address port connected to the switch is connected to the first common port, and when the switch is turned off, the first address port connected to the switch is disconnected from the first common port.

[0047] In this embodiment, the first address port and the first common port can be directly connected by a connecting line, or they can be connected by adding a switch, such as a dip switch, so as to manually set the corresponding address signal. Of course, in addition to the above schemes, the connection between the first address port and the first common port can also be achieved by means of relays, MOS tubes, jumper caps, and flat cables.

[0048] As an optional embodiment, the address configuration device further includes:

[0049] The control circuit connected to each switch triggers the switch to be turned on or off according to the configuration information.

[0050] In this embodiment, the group charging system including the address configuration device also includes a control circuit, which is used to output the switch signal required for each switch in the setting circuit 11 according to the configuration information, so that the corresponding first address port is connected to the first common port, and the other first address ports are left floating.

[0051] As an optional embodiment, the address configuration signal includes a plurality of address bit information corresponding to the plurality of first address ports one by one, each address bit information is determined based on the current state of the first address port and the first common port corresponding thereto, and the current state includes a connected state or a disconnected state;

[0052] The detection circuit 12 includes a plurality of detection units corresponding to the plurality of first address ports one by one. When the second connector is connected to the first connector, the detection unit is triggered to obtain address bit information and convert the address bit information into identification bit information; all identification bit information constitutes an address identification signal.

[0053] It can be understood that the address bit information corresponding to the connected state and the disconnected state is different. For example, the address bit information corresponding to the connected state is 1, and the address bit information corresponding to the disconnected state is 0. Assume that the configuration circuit includes four first address ports, namely PORT 1, PORT 2, PORT 3, and PORT 4, among which PORT 1 is connected to PORT C, then the address bit information corresponding to PORT 1 is 1, PORT 2 is connected to PORT C, then the address bit information corresponding to PORT 2 is 1, PORT 3 and PORT 4 are suspended, then the address bit information corresponding to PORT 3 and PORT 4 are both 0, then the address configuration signal of the first connector is 1100.

[0054] In this embodiment, the detection circuit 12 includes multiple detection units, and the number of the detection units is the same as the number of the first address ports in the configuration circuit. If the configuration circuit includes four first address ports, the second device is provided with four detection units, namely the first detection unit, the second detection unit, the third detection unit and the fourth detection unit. When the second connector is connected to the first connector, the first detection unit is connected to the first address port PORT 1 and the first common port PORT C, determines the connection state of PORT 1 and PORT C, and outputs the first identification bit information. The second detection unit is connected to the first address port PORT 2 and the first common port PORT C, determines the connection state of PORT 2 and PORT C, and outputs the second identification bit information. The third detection unit is connected to the first address port PORT 3 and the first common port PORT C, determines the connection state of PORT 3 and PORT C, and outputs the third identification bit information. The input end of the fourth detection unit is connected to the first address port PORT 4 and the first common port PORT C, determines the connection state of PORT 4 and PORT C, and outputs the fourth identification bit information. The address of the second device can be determined by the address identification signal obtained according to all the identification bit information.

[0055] As an optional embodiment, refer to Figure 4As shown, the detection unit includes a second address port, a second common port and an identification output port. When the first connector and the second connector are connected, the second address port is connected to the first address port of the detection unit in one-to-one correspondence. The second address port is used to access the address bit information. The identification output port is used to output the identification bit information corresponding to the address bit information. The second common port is connected to the first common port. The detection unit also includes a first resistor R1, a second resistor R2, a third resistor R3 and a switch tube Q1, wherein:

[0056] The first end of the first resistor R1 is connected to the first power supply, the common end of the second end of the first resistor R1 and the second resistor R2 is used as the second address port, the second end of the second resistor R2 is connected to the control end of the switch tube Q1, the first end of the switch tube Q1 and the second common port are both grounded, the common end of the second end of the switch tube Q1 and the first end of the third resistor R3 is used as the identification output port, and the second end of the third resistor R3 is connected to the second power supply.

[0057] As an optional embodiment, the detection unit further includes a first capacitor C1, a first end of the first capacitor C1 is connected to the second address port, and a second end of the first capacitor C1 is connected to the second common port.

[0058] As an optional embodiment, the detection unit also includes a second capacitor C2 and a fourth resistor R4, the first end of the fourth resistor R4 is connected to the second end of the switch tube Q1, the common end after the second end of the fourth resistor R4 is connected to the first end of the second capacitor C2 serves as an identification output port, and the second end of the second capacitor C2 is grounded.

[0059] In this embodiment, the switch tube Q1 is explained by taking a transistor as an example. The first resistor R1 is connected to the first power supply VCC_5V as a pull-up resistor to provide power and energy for the setting circuit 11. At the same time, a stable level is given when the setting circuit 11 is suspended. The first capacitor C1 can filter out interference at the second address port and the second common port. The second resistor R2 is the base current limiter of the transistor and provides current for it through VCC_5V. The fourth resistor R4 and the second capacitor C2 form an RC filtering circuit in the later stage to filter the address recognition signal entering the GPIO detection to ensure the accuracy of the detection. The third resistor R3 is a pull-up resistor with a similar function to the first resistor R1. The third resistor is connected to the second power supply VCC_3.3V.

[0060] As an optional embodiment, the first device includes a plurality of first connectors, the number of the setting circuits 11 is multiple, and the multiple setting circuits 11 are connected to the multiple first connectors in a one-to-one correspondence.

[0061] In a certain application scenario, the scenario may include multiple third devices with unified address settings, the third devices may include at least one first device, each first device includes multiple first connectors and multiple setting circuits 11, and the second device is correspondingly provided with multiple detection circuits 12. When the second device is connected to the first connector on any first device, the address configuration scheme of the present application is adopted to accurately identify the address of the second device, and the specific location of the second device connected in the scenario can be accurately identified through the address. Figure 5 As shown, Figure 5 The first connector is indicated by a socket, and the second connector is indicated by a plug. Assume that a certain scenario includes two third devices, each of which includes two first devices, and each of which includes four configuration circuits for address recognition of the second device. The third device C1 includes two first devices, and each first device can be connected to four second devices. As long as the second device is plugged into the socket of any first device, the location of the second device (the corresponding superior first device, the superior superior third device) can be determined. Setting circuit 11 mainly refers to the routing or connection of setting circuit 11 at the first device (it can also be manually set using a dip switch). When it is necessary to distinguish different addresses, setting circuit 11 is connected to PORTC through the first address port PORT 1~PORT n or left floating to determine the level of the PORT bit.

[0062] In summary, in this embodiment, for a system containing multiple products, the hardware address of the product that needs to be clearly distinguished in physical location can be set and identified so that it can be found immediately when looking for the product. At the same time, for products that do not need to be clearly distinguished in physical location, their addresses can be set through software, which can save hardware resources.

[0063] Second, please refer to Figure 6 , Figure 6 This is a structural schematic diagram of a group charging system including an address configuration device provided by the present application. The group charging system including the address configuration device includes:

[0064] Q charging cabinets 61 connected in communication, Q is a positive integer;

[0065] Each charging cabinet 61 includes an address configuration device 62 as described in any of the above embodiments;

[0066] The processing device 63 connected to the address configuration device is used to trigger one or more first address ports in the configuration circuit of the address configuration device to connect to the first common port according to the received address recognition table.

[0067] As an optional embodiment, the address configuration device 62 further includes a detection circuit, and each charging cabinet 61 further includes X backplanes, each backplane is connected to M modules, and each module is provided with Z1 detection circuits, where Z1=2 N+Y+T-1 , 2 N-1 <M≤2 N , 2 Y-1 <M≤2 Y , 2 T-1 <Q≤2 T .

[0068] As an optional embodiment, the address configuration device 62 further includes a detection circuit, and each charging cabinet 61 further includes X backplanes, each backplane is connected to M modules, and each module is provided with Z2 detection circuits, where Z2=2 L , 2 L-1 <M+X+Q≤2 L .

[0069] The modules include but are not limited to charging modules or power distribution modules and other modular products that require clear address information in the charging system.

[0070] In this embodiment, a charging system is used as an example to illustrate that the number of configuration circuits and detection circuits can be determined according to the number of charging piles in the charging system, the number of backplanes on each charging pile, and the number of modules supported by the backplane. Specifically, when a backplane B can be plugged with a maximum of M modules A, it is necessary to calculate M to satisfy 2 N-1 <M≤2 N In order to distinguish the address of module A, N detection circuits need to be designed in module A. For example, when M=2, N=1 is calculated. When a product C contains X backplanes B, it is necessary to calculate X to satisfy 2 Y-1 <M≤2 Y In order to distinguish the address of backplane B, it is necessary to design Y detection circuits in module A. For example, when X=2, Y=1. When an application scenario requires Q products C, it is necessary to calculate Q to satisfy 2 T-1 <Q≤2 T , so that when there are Q products C, each product C includes X backplanes, and each backplane B is connected to M modules A, it is necessary to design Z1 detection circuits in each module A, Z1 = 2 N+Y+T-1 In order to distinguish the address of product C, it is necessary to design T detection circuits in module A. For example, when Q=2, T=1. If the charging system is not expanded, the number of detection circuits required is Z2=2 L , 2 L-1 <M+X+Q≤2 L At this time, the determined detection circuit has been shared by backplane B, module A and product C, and the address cannot be further expanded.

[0071] Therefore, in order to meet the hardware address recognition, it is necessary to design Z=2 in module A. N+Y+T-1 4 detection circuits are enough. For example, when M=2, X=2, Q=1, we get N=1, Y=1, T=1, and Z=4. Therefore, each module A needs to design 4 detection circuits. Next, we need to determine the product address recognition table, and use 1 to represent the high level detected by the PORT detection port, and use 0 to represent the low level detected (interchangeable), and set the address sequence for all PORTs from all 0 to all 1 (such as 000, 001, 010...111, this is just for the convenience of example, it can actually start and end at any position). Just put 2 N+Y+T ~2 0 All are converted into (N+Y+T)-bit binary numbers and listed with the high bit first and the low bit last, and finally the set address and the corresponding comparison table are obtained. For example, when M=2, X=2, Q=2, the calculation results are N=1, Y=1, T=1, and Z=4 are continued. The list is as follows:

[0072] Table 1 Address recognition table when M=2, X=2, Q=2

[0073]

[0074] Next, configure the configuration circuit according to the above address recognition table. Because the detection circuit will undergo voltage inversion, it is assumed that the detection circuit is represented by 1 when it detects a high level and by 0 when it detects a low level. Therefore, the PORT bit represented by 0 in Table 1 is left floating in the setting circuit corresponding to the backplane B, and the PORT bit represented by 1 is connected to PORTC in the setting circuit corresponding to the backplane B. For example, PORT4 of module A corresponding to position A1 in backplane B1 of product C1 is left floating, PORT3 is left floating, PORT2 is left floating, and PORT1 is left floating; PORT4 of module A corresponding to position A2 in backplane B2 of product C1 is left floating, PORT3 is connected to PORTC, PORT2 is left floating, and PORT1 is connected to PORTC. The above method of obtaining the address recognition table is only for illustration and is not the focus of protection of this application.

[0075] It should also be noted that, in this specification, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "comprises", "comprising" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device.
