It should be understood that the terms used in this way can be interchangeable under appropriate circumstances, which is only to describe the distinction mode adopted by the objects of the same attributes when describing in the embodiments of the present application. In addition, the terms "including" and "having" and any of their variations are intended to cover non-exclusive inclusions, so that the process, method, system, product or equipment comprising a series of units need not be limited to those units, but may include other units that are not clearly listed or inherent to these processes, methods, products or equipment.

[0046] The embodiment of the present application provides a charging station, including a plurality of charging piles, wherein the charging piles communicate with other charging piles through an internal communication network of the charging station. The internal communication network of the charging station can be a wired network or a wireless network.

[0047] See also Figure 1 , Figure 1The schematic diagram of the structure of a charging station is shown. The charging station includes multiple charging piles 101 and switches 102, and the multiple charging piles 101 and switches 102 form an internal communication network. The charging piles 101 have Ethernet interfaces, and the charging piles 101 and switches 102 are connected by Ethernet wires. The wired connection is stable and reliable, and has strong anti-interference ability.

[0048] The embodiment of the present application provides a communication control method for a charging pile, which is applied to a charging pile in a charging station. The communication control method for a charging pile in the embodiment of the present application is described in detail below with reference to the accompanying drawings.

[0049] See also Figure 2 , Figure 2 A flow chart of a communication control method for a charging pile provided in an embodiment of the present application is shown as follows: Figure 2 As shown, a communication control method for a charging pile provided in an embodiment of the present application includes steps 201-202, and these steps are described in detail below.

[0050] 201: Obtain the number of online charging piles in the charging station, wherein each online charging pile communicates with other online charging piles through an internal communication network of the charging station;

[0051] The charging pile obtains the number of online charging piles in the charging station according to the communication status with other charging piles.

[0052] Exemplarily, each charging pile runs an online detection service in real time. The online detection service sends heartbeat information to other charging piles and receives heartbeat information sent by other charging piles, and determines the number of online charging piles according to the number of received heartbeat information.

[0053] 202: If the number of online charging piles reaches a first threshold, a master pile is determined among the online charging piles, and other online charging piles in the charging station are determined as slave piles, wherein the master pile is used to communicate with the network side device, and the slave piles communicate with the network side device through the master pile.

[0054] The first threshold is greater than or equal to 2. If the number of online charging piles is less than the first threshold, it means that the number of online charging piles is too small, and it is unnecessary to adopt master-slave pile communication.

[0055] After the master pile is generated, the master pile broadcasts the master pile information in the internal communication network of the charging station. After receiving the master pile information, other online charging piles are regarded as slave piles by default, and then establish master-slave pile communication. For example, taking the charging station including 6 online charging piles as an example, after charging pile 1 is determined as the master pile, the other 5 online charging piles respectively establish heartbeat responses with charging pile 1.

[0056] After establishing the master-slave pile communication, the master pile is used to communicate with the target device, which can be a network-side device, such as a cloud server, platform server, etc. The master pile acts as a relay device between the network-side device and the slave pile, forwarding the information sent by the slave pile to the network-side device, and forwarding the information sent by the network-side device to the slave pile. For the sake of convenience, this communication mode is defined as the group control mode below.

[0057] The present embodiment discloses a communication control method for a charging pile, which constructs an internal communication network at a charging station. An online charging pile communicates with other online charging piles through the internal communication network. When the number of online charging piles reaches a first threshold, a master pile is determined among the online charging piles, and other online charging piles are determined as slave piles, so that the master pile communicates with a network side device, and the slave pile communicates with the network side device through the master pile. Compared with all charging piles communicating with the network side individually, this method not only reduces the communication pressure on the network side device, but also reduces the communication cost generated by the communication between the charging pile and the network side device.

[0058] There are many ways to determine the master pile among various online charging piles.

[0059] In a possible implementation, according to the numbers of the online charging piles, the online charging pile with the largest number, the smallest number, or a preset number is determined as the main pile.

[0060] In another possible implementation, the communication status of each online charging pile is obtained, and the charging pile with the best communication status is determined as the main pile. For example, each online charging pile performs communication debugging at the same time, and notifies other online charging piles after completing communication debugging, and the online charging pile that completes communication debugging first is determined as the main pile.

[0061] In another possible implementation, each online charging pile executes a local election process in the internal communication network of the charging station. Each online charging pile broadcasts the election results in the internal communication network. After each online charging pile receives the election results of other online charging piles, it determines the master pile according to a preset election algorithm, wherein the preset election algorithm can be any election algorithm.

[0062] The above three implementation methods are only examples, and the present application is not limited thereto.

[0063] In a possible implementation, when the charging station meets the preset exit group control condition, the master pile is cancelled, and each charging pile communicates directly with the target device.

[0064] In one embodiment, if the number of disconnected slave piles is greater than a second threshold, the charging station meets the preset conditions for exiting group control, and each charging pile communicates directly with the target device, wherein the second threshold can be a fixed value or can be set according to the scale of the charging station, such as the second threshold being the number of charging piles in the charging station multiplied by a preset ratio.

[0065] In one embodiment, if the number of online charging piles is less than the third threshold, the charging station meets the preset exit group control condition, and each charging pile directly communicates with the target device, wherein the third threshold is greater than or equal to 2. For example, there may be charging piles in the charging station that are in maintenance state, and some charging piles are temporarily powered off, resulting in only one online charging pile remaining, then the number of online charging piles is too small to meet the preset exit group control condition.

[0066] In one embodiment, if the number of times the step of determining the main pile is executed within the preset time is greater than the fourth threshold, the charging station meets the preset exit group control condition. This situation often occurs when the network is abnormal or the switch router equipment fails, and the switching between the group control mode and the non-group control mode occurs frequently. At this time, the group control mode is unstable. In order to ensure the normal operation of the charging pile, each charging pile communicates directly with the target device. Among them, the preset time and the fourth threshold are set according to the actual application scenario, and the preset time is positively correlated with the fourth threshold, that is, the longer the preset time, the larger the fourth threshold. For example, the preset time is 1 hour, and the fourth threshold is 10 times, that is, if the number of times the step of determining the main pile is executed within 1 hour is greater than 10 times, the charging pile meets the preset exit group control condition.

[0067] Correspondingly, when the charging station meets the preset group control condition, step 201 in the above embodiment is executed.

[0068] For example, the preset group control condition is: the charging pile receives a remote upgrade instruction. In this scenario, the master pile completes the upgrade by communicating with the target device, and then the master pile performs local upgrades on the slave pile, thereby improving the upgrade efficiency and reliability and avoiding the charging pile from missing the upgrade.

[0069] Exemplarily, the preset group control condition is: the charging pile receives the power dispatch instruction of the whole station. In this scenario, the target device dispatches the power of the slave pile through the master pile to improve the power dispatch efficiency.

[0070] Exemplarily, the preset group control condition is: the internal communication network of the charging station is in a normal state. In this case, as long as the internal communication network of the charging station is in a normal state and the number of online charging piles reaches the first threshold, the group control mode is adopted, which not only reduces the communication pressure of the target device, but also reduces the communication cost generated by the communication between the charging pile and the target device.

[0071] The embodiment of the present application further provides a charging pile, comprising at least one processor and a memory connected to the processor, wherein:

[0072] The memory is used to store computer programs;

[0073] The processor is used to execute the computer program so that the charging pile can implement any one of the communication control methods for the charging pile provided in the embodiments of the present application.

[0074] It is understandable that the charging pile also includes charging guns, display screens, charging modules and other equipment, which will not be elaborated here.

[0075] An embodiment of the present application also provides a computer program product including computer-readable instructions. When the computer-readable instructions are executed on a charging pile, the charging pile implements any one of the communication control methods for the charging pile provided in the embodiment of the present application.

[0076] A computer-readable storage medium is also provided in an embodiment of the present application. The storage medium carries one or more computer programs. When the one or more computer programs are executed by the charging pile, the charging pile can implement any communication control method of the charging pile provided in the embodiment of the present application.

[0077] An embodiment of the present application also provides a charging station, including: a new energy system, multiple charging piles and a middle-end device, the new energy system includes at least one of a new energy power generation system and an energy storage system, the middle-end device is communicated and connected with the new energy system and the multiple charging piles respectively through the internal communication network of the charging station, wherein the new energy power generation system can be a photovoltaic system.

[0078] See also Figure 3 , Figure 3 A schematic diagram of the structure of a charging station is shown, in which the solid line represents the power output line and the dotted line represents the communication line. The charging station includes multiple charging piles 301, switches 302, routers 303, middle station equipment 304, energy storage systems 305 and photovoltaic systems 306. The charging piles 301, energy storage systems 305 and photovoltaic systems 306 have Ethernet interfaces. The charging piles 301, energy storage systems 305, photovoltaic systems 306 and switches 302 are connected by Ethernet wires. The middle station equipment 304 is connected to the charging piles 301, energy storage systems 305 and photovoltaic systems 306 through routers 303 and switches 302.

[0079] Taking the photovoltaic system as an example, the output phases of the photovoltaic system and the energy storage system are different. The photovoltaic system mainly generates solar power during the day, while the energy storage system can absorb and release the power generated by the photovoltaic system in accordance with the time-of-use electricity price period. As a load of power consumption, the charging pile can automatically switch the communication mode according to the different output time periods of the photovoltaic system and the energy storage system to cooperate with the photovoltaic system and the energy storage system to improve the charging efficiency and maximize the customer's interests.

[0080] The communication modes of charging piles in the charging station include: normal mode, single control mode and group control mode.

[0081] In normal mode, each charging pile communicates directly with the network side device.

[0082] In single control mode, each charging pile communicates with the middle station device separately.

[0083] In the group control mode, the master pile communicates with the middle-end device, and the slave pile communicates with the middle-end device through the master pile.

[0084] The embodiment of the present application provides a communication control method for a charging pile, which is applied to a middle station device in a charging station. The communication control method for a charging pile in the embodiment of the present application is described in detail below with reference to the accompanying drawings.

[0085] See also Figure 4 , Figure 4 A flow chart of a communication control method for a charging pile provided in an embodiment of the present application is shown as follows: Figure 4 As shown, a communication control method for a charging pile provided in an embodiment of the present application includes steps 401-402, and these steps are described in detail below.

[0086] 401: Obtain the number of online charging piles in the charging station, wherein each online charging pile communicates with other online charging piles through an internal communication network of the charging station;

[0087] The middleware obtains the number of online charging piles in the charging station based on the communication status with the charging piles.

[0088] Exemplarily, the middle station device runs an online detection service in real time, and monitors whether each charging pile is online by establishing a heartbeat response with each charging pile, thereby determining the number of online charging piles.

[0089] 402: If the number of online charging piles reaches a first threshold, a master pile is determined among the online charging piles, and other online charging piles in the charging station are determined as slave piles, wherein the master pile is used to communicate with the middle station device, and the slave piles communicate with the middle station device through the master pile.

[0090] The first threshold is greater than or equal to 2. If the number of online charging piles is less than the first threshold, it means that the number of online charging piles is too small, and it is unnecessary to adopt master-slave pile communication.

[0091] After the master pile is generated, the master pile broadcasts the master pile information in the internal communication network of the charging station. After receiving the master pile information, other online charging piles default to being slave piles, and then establish master-slave pile communication.

[0092] After establishing the communication between the master and slave piles, the middle station device adopts the group control mode for the charging piles. The middle station device communicates with the master pile. The master pile acts as a relay device between the middle station device and the slave piles, forwarding the information sent by the slave pile to the middle station device, and forwarding the information sent by the middle station device to the slave piles.

[0093] The method of determining the master pile among the online charging piles is the same as that of the embodiment corresponding to step 202, and will not be described in detail here.

[0094] The present embodiment discloses a communication control method for a charging pile, which constructs an internal communication network at a charging station. The online charging piles communicate with other online charging piles through the internal communication network. When the number of online charging piles reaches a first threshold, a master pile is determined among the online charging piles, and other online charging piles are determined as slave piles. The master pile communicates with the middle-end device, and the slave piles communicate with the middle-end device through the master pile. Compared with all charging piles communicating with the middle-end separately, this method not only reduces the communication pressure on the middle-end device, but also reduces the communication cost generated by the communication between the charging piles and the middle-end device.

[0095] like Figure 5 The communication mode switching diagram shown in the figure shows that the normal mode, group control mode and single control mode can be switched. In the normal mode, the charging pile will not be dispatched by the middle station equipment, and the middle station equipment can dispatch the energy storage system and the new energy power generation system. In the single control mode and group control mode, the charging pile is dispatched by the middle station equipment. The following is a detailed introduction to the switching of the three communication modes.

[0096] In one possible implementation, the charging station meets the preset group control condition if the operating data of the new energy system meets the preset middle station scheduling condition.

[0097] If the new energy system includes a new energy power generation system, the preset middle station scheduling condition is: the power generation of the new energy power generation system is greater than the fifth threshold and the current time period belongs to the valley period in the time-of-use electricity price period, that is, the power generation of the new energy power generation system is high and the time-of-use electricity price is low.

[0098] If the new energy system includes an energy storage system, the preset middle station scheduling conditions are: the energy storage capacity of the energy storage system is greater than the sixth threshold and the current time period belongs to the valley period in the time-of-use electricity price period, that is, the energy storage capacity of the energy storage system is large and the time-of-use electricity price is low.

[0099] If the new energy system includes a new energy power generation system and an energy storage system, the preset middle station scheduling conditions are: the power generation of the new energy power generation system is greater than the fifth threshold or the energy storage system is greater than the sixth threshold, and the current time period belongs to the valley period in the time-of-use electricity price period, that is, the power generation of the new energy power generation system is high or the energy storage system is high, and the time-of-use electricity price is low.

[0100] The fifth and sixth thresholds above can be set according to the actual application scenario. Meeting the preset middle station scheduling conditions indicates that the current power generation is in excess or the energy storage is in excess, and the time-of-use electricity price is low. It is not suitable to connect the excess power generation or excess energy storage to the grid. It is preferred to use the excess power generation or excess energy storage for charging piles.

[0101] When the charging station meets the preset group control conditions, the middle station device obtains the number of online charging piles in the charging station. If the number of online charging piles reaches the first threshold, the normal mode is switched to the group control mode. If the number of online charging piles does not reach the first threshold, the normal mode is switched to the single control mode.

[0102] If the charging station does not meet the preset group control conditions, each charging pile communicates with the network side device separately, that is, the normal mode is adopted.

[0103] Take the charging station including photovoltaic power generation system and energy storage system as an example, please refer to Figure 6 The flow chart of the communication control method of the charging pile shown is that the charging pile initially enters the normal mode. At this time, the middle station equipment determines whether the preset middle station scheduling conditions are met based on the operating data of the photovoltaic power generation system and the energy storage system. Specifically: first perform an energy storage system test. If the energy storage capacity of the energy storage system is greater than the sixth threshold and the current time period belongs to the valley section in the time-sharing electricity price period, the preset middle station scheduling conditions are met; if the energy storage system does not meet the preset middle station scheduling conditions, perform a photovoltaic system test. If the power generation of the photovoltaic system is greater than the fifth threshold and the current time period belongs to the valley section in the time-sharing electricity price period, the preset middle station scheduling conditions are met. It should be noted that the photovoltaic system test can also be performed first. If the photovoltaic system does not meet the preset middle station scheduling conditions, then perform an energy storage system test.

[0104] If the preset middle station scheduling conditions are not met, the normal mode will continue to be executed.

[0105] If the preset middle-station scheduling conditions are met, the charging piles will be checked online. If the number of online charging piles reaches the first threshold, the normal mode will be switched to the group control mode. In the group control mode, the middle-station device will not communicate with all charging piles, but only with the main pile, which can release the computing power of the middle-station device to a greater extent. At this time, the communication architecture is more robust and the charging station system is more stable.

[0106] If the group control mode switch fails, the normal mode will be switched to the single control mode.

[0107] If the number of online charging piles does not reach the first threshold, the normal mode is switched to the single control mode.

[0108] When switching to single-control mode, if the switch fails, the normal mode will continue to be executed.

[0109] When switching to single control mode or group control mode, the middle station device schedules the charging piles. The specific scheduling strategy is set according to the actual application scenario and is not specifically limited here.

[0110] It should be noted that after switching to the single control mode, if the number of online charging piles reaches a first threshold, the single control mode is switched to the group control mode.

[0111] When the charging pile adopts single control mode or group control mode, the middle station equipment continues to determine whether the preset middle station scheduling conditions are met based on the operating data of the photovoltaic power generation system and the energy storage system. If the middle station scheduling conditions are not met, the single control mode or group control mode is switched to normal mode, and the middle station equipment cannot schedule the charging pile. At this time, the middle station equipment will actively send a mode switching command to the charging pile, and the charging pile will respond to the mode switching command and switch to normal mode.

[0112] The embodiment of the present application also provides a middleware device, including at least one processor and a memory connected to the processor, wherein:

[0113] The memory is used to store computer programs;

[0114] The processor is used to execute the computer program so that the middle station device can implement the communication control method of the charging pile provided in the embodiment of the present application.
