Description

Technical Field

[0001] The present invention belongs to the field of charging piles, and relates to a charging pile, a charging pile group and a distribution method for automatically distributing charging modules. Background Art

[0002] Nowadays, there are more and more charging pile companies on the market, and more and more charging piles are being developed. The current charging piles provide different charging powers and achieve different charging speeds according to the number of charging modules. More and more charging piles use multiple charging guns to achieve different charging power requirements, but the power between different charging guns is fixed, and power cannot be distributed according to demand. Summary of the invention

[0003] The purpose of the present invention is to overcome the shortcomings of the above-mentioned prior art and provide a charging pile, a charging pile group and an allocation method for automatically allocating charging modules, so as to realize mobile allocation of charging modules and meet the different power requirements of charging guns.

[0004] In order to achieve the above object, the present invention adopts the following technical solutions: A charging pile for automatically allocating charging modules, comprising a plurality of charging module slots; Multiple charging module slots are divided into multiple layers according to the number of charging guns. A charging module inlet and a charging module outlet are arranged on the side of the charging pile. The charging module inlet, the charging module outlet and each charging module slot are connected with the vertical lifting track through a horizontal track. Track robots are arranged on the horizontal track and the vertical lifting track. The charging module slot and the track robot are connected with a charging module call monitoring board.

[0005] Preferably, spare slots are provided outside each layer of charging module slots.

[0006] Preferably, a fault position is provided outside the charging module slot.

[0007] A charging module allocation method for a charging pile. When any charging gun in the charging pile requires a charging module, the required number of charging modules or power is sent to the charging module calling monitoring board. The charging module calls the monitoring board to transmit the request for the charging module. The track robot grabs the corresponding number of charging modules in turn, moves through the horizontal track and the vertical lifting track in turn and places them in the charging module slots of the corresponding layer of the charging gun. All communication and power lines are automatically plugged in, and charging begins after the charging pile system responds that the charging module has been successfully received.

[0008] Preferably, when the charging module calls the monitoring board and receives a demand, the charging module calls the monitoring board to determine whether there is a charging module in the charging module slot of the corresponding layer. If the number of charging modules in the corresponding layer is insufficient, the track robot grabs the charging module in the spare slot or the idle charging modules in the other layers.

[0009] Preferably, if the power requirement is still not met after all charging modules are placed in the charging module slots of the corresponding layer, the charging gun calls on the charging modules in the charging module slots of other layers.

[0010] A charging pile group for automatically allocating charging modules, comprising a plurality of charging piles for automatically allocating charging modules; The charging module inlet and the charging module outlet of each charging pile are connected with the charging module outlets and the charging module inlets of two adjacent charging piles through a horizontal track.

[0011] Preferably, the horizontal track inside the charging pile is connected to the horizontal track outside the charging pile from the charging module inlet.

[0012] A charging module allocation method for a charging pile group. When a charging pile has a charging module demand but does not have enough charging modules, a request instruction is sent to a power scheduling monitoring board. After receiving the instruction, the power scheduling monitoring board transports the idle charging modules in adjacent charging piles to the charging piles in demand through horizontal tracks between the charging piles.

[0013] Preferably, the process of transporting the charging module between the two charging piles is as follows: the track robot moves the idle charging module from the inside of the charging pile, through the charging module outlet to the horizontal track between the two charging piles, until there is a charging module entrance of the required charging pile at the end of the horizontal track. The track robot of the required charging pile receives the charging module from its own charging module entrance and places it in its own required charging module slot.

[0014] Compared with the prior art, the present invention has the following beneficial effects: The present invention connects the charging module inlet, the charging module outlet and each charging module slot through a horizontal track and a vertical lifting track. A track robot is provided on the horizontal track and the vertical lifting track. The movement of the charging module is realized by the track robot, so that each charging module in the charging pile can be automatically moved into the corresponding charging module slot. By increasing or decreasing the number of charging modules on the corresponding layer of the charging gun, the output power of the charging gun can be changed.

[0015] Furthermore, multiple charging piles share charging modules through a dual-circuit method. When the output capacity of one of the charging piles is too small, but the output power is low due to the limited number of charging modules, the charging module can be called through the connection charging module path of the two charging piles to meet the charging power demand.

In order to simplify the disclosure of the present invention, the parts and settings of specific examples are described below. Of course, they are only examples, and the purpose is not to limit the present invention.

In addition, the present invention provides various specific examples of processes and materials, but those of ordinary skill in the art can be aware of the application of other processes and / or the use of other materials.

[0021] like Figure 1 As shown, the charging pile for automatically allocating charging modules according to the present invention is internally configured with multiple charging module slots, which are divided into multiple layers according to the number of charging guns. The charging pile side is provided with a charging module import and a charging module export. In order to make the charging pile more convenient, a spare slot is provided outside each layer of the charging module slot, specifically: spare position 1, spare position 2 and a fault position can be configured at the charging module export. The three slots can be used according to the configuration of the charging pile. For example, after a charging module fails, it can be placed in the fault position. If a charging module is frequently called and called out, the charging module can be placed in the spare position for ready to be called out or called for use. At the same time, the spare position can also be configured as a fault position. The principle of the charging pile is similar to that of an elevator. The number or power of charging modules required for each layer is sent to the charging module call monitoring board, and the charging module call monitoring board performs the request transmission and request return of the charging module. Therefore, when the charging module enters the charging pile, the configured ID will be stored in the charging module call monitoring board for charging module information identification, which can accurately locate the status of the charging module and the location of the charging module.

[0022] The charging module inlet, charging module outlet, spare position 1, spare position 2, fault position and each charging module slot are connected to the vertical lifting track through a horizontal track. Track robots are arranged on the horizontal track and the vertical lifting track. The charging module is grasped and placed by the track robot, and the charging module is moved, placed into the charging module slot or taken out from the charging module slot.

[0023] In this embodiment, 9 charging module slots are configured, which are divided into 3 layers according to 3 charging guns, with 3 charging module slots in each layer. When a single charging pile only calls the charging module in its own system, when any charging gun in its own system requires a charging module, the charging module can be placed in the charging module slot corresponding to the charging gun. For example: the charging module slots corresponding to charging gun No. 1 are charging module No. 1, charging module No. 2, and charging module No. 3; the charging module slots corresponding to charging gun No. 2 are charging module No. 4, charging module No. 5, and charging module No. 6; the charging module slots corresponding to charging gun No. 3 are charging module No. 7, charging module No. 8, and charging module No. 9.

[0024] When all charging module slots are fully equipped with charging modules, that is, charging module No. 1 exists in charging module slot 1, and charging modules No. 2 and No. 3 exist in charging module slots 2 and 3; assuming that the charging module power is 20kW and the required power of charging gun No. 1 is 15kW, the charging module in charging module slot No. 1 can be called; assuming that the charging module power is 20kW and the required power of charging gun No. 1 is 30kW, the charging module No. 1 in charging module slot 1 and the charging module No. 2 in charging module slot 2 can be called; assuming that the charging module power is 70kW and the required power of charging gun No. 1 is 30kW, the charging module No. 1 in charging module slot 1, the charging module No. 2 in charging module slot 2, the charging module No. 3 in charging module slot 3, and the charging module No. 4 in charging module slot 4 can be called. When the charging gun No. 2 added later finds that the charging module slot No. 4 is already occupied, it will first call the charging modules in charging module slots 5 and 6 until the charging demand is met.

[0025] The power between each charging module slot can be output controlled to meet the operation of the charging modules in the used charging module slots; when the configured terminal or charging gun outputs power, the power output is normal, and no voltage series connection will be generated between terminals or between charging guns; the charging process must be implemented in accordance with national standards.

[0026] like Figure 2As shown, the charging pile group for automatically allocating charging modules of the present invention includes a plurality of the above-mentioned charging piles for automatically allocating charging modules. The charging module inlet and the charging module outlet of each charging pile are connected with the charging module outlets and the charging module inlet of two adjacent charging piles through a horizontal track. The charging module call between multiple charging piles can be completed through the power dispatching monitoring board. The power dispatching monitoring board can complete the identification of the internal charging module information of a single charging pile and the internal charging module call. At the same time, the rail robot control of the charging module inlet and the charging module outlet can be monitored and controlled, including the control of the exit and entry implementation method of the charging module from the charging module slot of each layer and the definition of all charging module slots. The horizontal track inside the charging pile is connected from the charging module inlet to the horizontal track outside the charging pile. The rail robot can move the charging module from the inside of the charging pile through the charging module outlet to the horizontal track between the two charging piles until the charging module inlet of another charging pile at the end of the horizontal track. The rail robot of the other charging pile receives the charging module from its own charging module inlet to realize the movement of the charging module between the charging piles. The power monitoring and dispatching board can detect the movement status of the channel between the charging piles to ensure the normal execution of the charging module call. When a fault occurs, timely feedback is given and the charging module or the channel usage permission is stopped according to the designed logic. From the above, it can be seen that the power monitoring and dispatching board can trace the operation trajectory of the charging module. At the same time, combined with the charging pile, the service life of the charging module can be known, the number of times the charging module is used can be set, and combined with the fault position, the charging module can be regularly exited.

[0027] like Figure 3 As shown, for a single charging pile, it is necessary to first set whether the charging pile joins in sharing the charging module with other charging piles. When sharing the charging module with other charging piles, its own idle charging module will participate in the call demand instructions of other charging piles; when the charging pile is set not to share the charging module with other charging piles, its own idle charging module only participates in the call of its own charging module.

[0028] When the charging module calls the monitoring board and receives the demand, the charging module calls the monitoring board to determine whether there is a charging module in the charging module slot of the corresponding layer. When there is a charging module in the charging module slot No. 1, and there is no charging module No. 2 and charging module No. 3 in the charging module slot No. 2 and charging module slot No. 3, when the charging module calls the monitoring board to execute the internal call demand of the single pile system, the charging module in the spare slot or the idle charging module in the remaining layers can be automatically moved to the position of charging module No. 2 and charging module No. 3 through the horizontal track and the vertical lifting track. When the movement is successful and all communication and power lines are automatically plugged in, the charging pile system can respond to the successful reception of the charging module, and then the charging start instruction can be issued. Once the called charging module is in the startup state, it will reply to the charging module call monitoring board to end the call task; the charging module power starts to output, the relay is closed, the power output starts protection, and the operating status of the charging module will always reply to the charging module call monitoring board. Once the charging module is charged, it can be restored to its own call system pool, waiting to be called again or used directly. Through the above logical design, the software can also fix some charging modules and only allow specific charging modules to be called back and forth; during the entire charging process, the charging pile will monitor and adjust the position of the charging module in real time to ensure that the charging module is fully equipped at any time and the system can run at full power, achieving optimal use of the system.

[0029] like Figure 4 As shown, this embodiment lists four charging piles to form a charging pile group. A single charging pile is configured with 9 charging modules and 3 charging guns to illustrate the operation logic of the charging pile group. However, the actual application system is not limited to the number of system charging modules, and does not limit the number of charging gun lines or the number of charging terminals. When charging pile No. 1 contains 9 charging modules, assuming that the power of each charging module is 20kW, the power required by charging pile No. 1 is 50kW, and charging pile No. 2 contains 5 charging modules, but the power required by charging pile No. 2 is 150kW, which is greater than the capacity of its own charging pile. At this moment, the required power instruction can be sent to the charging module call monitoring board, so that the extra idle charging modules inside charging pile No. 1 can be automatically moved to charging pile No. 2 through the horizontal track to realize the charging module call between piles; when the charging module call is successful and confirmed by the charging pile No. 2, the charging module call instruction ends, and it can participate in charging and control the output relay. At the same time as the relay is closed, the power output protection judgment logic is done well. After the charging module is used, it is not allowed to be called and the charging follows the national standard design.

[0030] When a charging pile has a demand for charging modules, but the number of its own charging modules is insufficient, a request instruction can be sent to the power scheduling monitoring board. When the power scheduling monitoring board receives the instruction, it will perform path algorithm screening in the charging piles shared by the charging modules, and select charging modules that can be used to increase power output at other charging piles. After the charging module moves to other charging piles, the charging pile and the charging module call the monitoring board for confirmation, and then the charging gun that needs charging can be quickly added. After the charging module is successfully started, the scheduling will end, and the charging pile will upload the charging module information to the power scheduling monitoring board in real time. Because the tracks between multiple charging piles are connected in series, divided into charging module imports and charging module exports, when there are many charging piles involved in power calling, there will be a problem of the length of the charging module calling path, so a simple optimal calling path calculation is required; when the entire charging pile group is in operation, some charging modules will not be used for a long time, and the service life of this charging module may be longer than that of other charging modules, so the logic that this charging module should be used first is involved; the path algorithm can be combined with the setting number of charging module service life for joint screening, so that the charging modules of the entire charging pile group can play their own value, which can reduce the aging problem of components when the charging modules are in standby for a long time.
