[0001] CROSS-REFERENCE TO RELATED APPLICATIONS

[0002] This application claims priority to the Chinese patent application filed with the State Intellectual Property Office of the People's Republic of China on November 1, 2023, with application number 202311444172.3 and invention name "A Charging Network, Electronic Device and Charging Pile", the entire contents of which are incorporated by reference into this application. Technical Field

[0003] The present application relates to the field of communication technology, and in particular to a charging network, electronic equipment and charging pile. Background Art

[0004] With the development of new energy vehicle technology, the market share of new energy vehicles is increasing, and new energy vehicle technology is becoming increasingly mature. However, the range anxiety and charging issues of new energy vehicles are still the pain points of concern to consumers. Therefore, it is necessary to build a large number of charging networks for users to charge new energy vehicles.

[0005] However, in current charging networks, most devices communicate via wired communication, resulting in high deployment costs, poor flexibility, and difficult repair and maintenance. As shown in Figure 1, in a wired charging network, charging piles and network devices (such as switches) must communicate via wired communication, as well as between charging piles. This results in numerous and complex wiring harnesses in the charging network, and the cost of trenching and wiring is high when arranging charging piles. Furthermore, after the wiring in the charging network is cemented, it is difficult to repair and maintain, and is not friendly to later deletions, expansions, or changes in the communication network configuration.

[0006] It can be seen that the new energy vehicle industry currently lacks a low-cost, flexible and easy-to-maintain charging network.

[0007] Summary of the Invention

[0008] The present application provides a charging network, electronic equipment and charging piles to reduce the equipment deployment cost in the charging network.

[0009] In a first aspect, an embodiment of the present application provides a charging network, which includes multiple charging piles and a first device, wherein the first device includes a first wireless communication module, and the first charging pile among the multiple charging piles includes a second wireless communication module; the second wireless communication module is used to send a first message to the first wireless communication module; wherein the first message includes information about the first charging pile and / or information about the charging terminal connected to the first charging pile; the first wireless communication module is used to receive the first message from the second wireless communication module.

[0010] In an embodiment of the present application, the information of the first charging pile may include but is not limited to at least one of the charging voltage, charging current, charging power, temperature, insulation status, identification, or software version. The charging terminal (i.e., charging equipment) may be, for example, a robot, a ship, a vehicle, an airplane, or other equipment that needs to be charged, and this embodiment of the present application does not limit this. The information of the charging terminal may, for example, include at least one of the user information associated with the charging terminal (such as vehicle identification number, owner contact information, etc.), the power information of the charging terminal, or the communication information of the battery management system. Among them, the communication information of the battery management system includes communication messages involved in related processes such as physical connection, low voltage assistance, charging handshake, charging parameter configuration, and charging stage.

[0011] In the charging network provided in the embodiments of the present application, a first device is provided with a first wireless communication module, and a first charging pile is provided with a wireless communication module, so that the first device and the first charging pile can exchange information by wireless communication. Thus, the first device and the first charging pile can be flexibly deployed in the charging network without the need to arrange a large number of wiring harnesses in the charging network, thereby effectively reducing the equipment deployment cost in the charging network. In addition, the first device can receive information about the first charging pile and / or information about the charging terminal connected to the first charging pile by wireless communication, so that the first device can subsequently analyze and process the information about the first charging pile and / or information about the charging terminal connected to the first charging pile.

[0012] In one possible design, the first device is a target charging pile or a station controller. In this design, the target charging pile in the charging network serves as the first device, eliminating the need for a separate station controller in the charging network. The target charging pile can collect and manage information about other charging piles in the charging network. Alternatively, a station controller can be set up in the charging network and used as the first device. This allows the station controller to collect and manage information about charging piles in the charging network. Furthermore, the station controller has significant computing power resources, so even if there are a large number of charging piles in the charging network, the station controller can still manage information about all charging piles.

[0013] In one possible design, the first device also includes a control module; the control module is used to generate a control instruction based on the first message, and the control instruction is used to instruct the first charging pile to perform a first operation; wherein, the first operation includes at least one of the following: adjusting charging parameters, payment operations, adjusting thermal management system, fault diagnosis, alarm, reset, or Over-the-Air Technology (OTA) upgrade; the first wireless communication module is also used to send the control instruction to the second wireless communication module; the second wireless communication module is also used to receive the control instruction from the first wireless communication module.

[0014] In this design, the first device can also control the first charging pile to perform corresponding operations. For example, the charging parameters of the first charging pile (such as charging power, charging voltage, charging current, etc.) are adjusted to make the charging parameter distribution of the first charging pile more reasonable. For another example, when the first charging pile is integrated with a billing system, the first charging pile can implement payment operations according to the control instructions. For another example, the first charging pile can also adjust the thermal management system of the first charging pile according to the control instructions to ensure the battery performance of the charging pile and improve the safety of the first charging pile. For another example, the first charging pile can also perform fault diagnosis according to the control instructions, so that the first charging pile can detect the fault in time and then respond to the fault in time. For another example, the first charging pile can also issue an alarm according to the control instructions, so that the user can promptly inspect and maintain the first charging pile. For another example, the first charging pile can also be reset according to the control instructions to implement certain fault repair functions (for example, restarting the rectifier power off, restarting the wireless communication module, restarting the power module, or restarting the main control, etc.). For example, the first charging pile can also implement OTA upgrades such as power control and distribution unit program upgrade, charging control unit program upgrade, billing control unit program upgrade, and master control reset according to control instructions.

Accordingly, the alarm information may be at least one of a voice message, a text message, or a picture message. In this design, the first device controls the prompt device to output the corresponding alarm information, so that the user can promptly inspect and maintain the fault of the first charging pile.

[0016] In one possible design, the first wireless communication module may further send a first message to a server. The first message includes information about the first charging pile and / or the charging terminal connected to the first charging pile. The server can then store the information about the first charging pile and / or the charging terminal connected to the first charging pile, and perform traceability analysis on the charging data of the first charging pile and / or the charging terminal connected to the first charging pile, thereby facilitating management and maintenance of the charging network.

[0017] In another possible design, the control module can also process the first message to obtain a processed first message; and then the first wireless communication module can also send the processed first message to the server. The first message includes information about the first charging pile and / or information about the charging terminal connected to the first charging pile. For example, the control module can perform fault diagnosis on the first charging pile based on the information about the first charging pile, and when the first charging pile fails, the information about the first charging pile is sent to the server. For another example, the control module can perform fault diagnosis on the charging terminal connected to the first charging pile based on the information about the charging terminal connected to the first charging pile, and when the charging terminal connected to the first charging pile fails, the information about the failed charging terminal is sent to the server. In this way, the server only stores key data in the charging network, reducing the memory occupied by the relevant data of the charging network stored on the server.

[0029] In one possible design, when the communication quality of the target charging pile does not meet the preset indicators, the third charging pile among the multiple charging piles is used as the new target charging pile in the charging network, and the third charging pile is determined based on the pre-configured information and / or the networking method of the multiple charging piles. Among them, in the networking method of the multiple charging piles, the original target charging pile can assign a charging pile as the new target charging pile among the charging piles whose communication quality meets the preset indicators (for example, the original target charging pile can send an indication message to the charging pile assigned to it), or any charging pile whose communication quality meets the preset indicators can send a broadcast message to all charging piles in the charging network, and the broadcast message is used to indicate that any charging pile will be the new target charging pile.

[0054] To facilitate understanding, some of the terms involved in the embodiments of this application are first introduced below.

[0055] 1. An integrated charging pile, which integrates the charging host and charging pile terminal (such as a charging gun, a charging induction base, etc.) of the charging pile into one device. Among them, the integrated charging pile can also be a machine that integrates multiple functional modules such as DC fast charging, AC slow charging, charging management system, billing system, communication module, etc., to form an overall device also known as a "wall charging pile" or "wall-mounted charging pile". It can be directly installed in a fixed position outdoors or indoors, and has the advantages of being safe and reliable, easy to operate, taking up little space, and having low energy consumption. It is suitable for places that require a large number of charging facilities, such as public parking lots, commercial centers, and office buildings. Exemplarily, the integrated charging pile can be as shown in Figure 2A, in which the charging host and charging pile terminal are integrated.

[0056] 2. Split charging pile, a charging pile in which the charging host and charging pile terminal of the charging pile are independently set. Among them, the charger can provide stable, reliable and adjustable AC power supply and DC power supply for the charging pile terminal, and the charging pile terminal can realize the charging operation of the charging terminal (such as electric vehicles, robots, ships, etc.). The split charging pile can be flexibly arranged in various places, and is more suitable for occasions that require temporary installation or movement, such as roadside parking spaces, residential areas, logistics warehousing, etc. Exemplarily, the split charging pile can be shown in Figure 2B, and the split charging pile includes a charging host, a charging pile terminal 1, a charging pile terminal 2, and a charging pile terminal 3. The charging host can provide AC power supply and DC power supply for the charging pile terminal 1-charging pile terminal 3, and the charging pile terminal 1-charging pile terminal 3 can charge different charging terminals respectively.

[0057] The present application provides a charging network, an electronic device, and a charging pile. In the charging network, a first device is provided with a first wireless communication module, and a first charging pile is provided with a wireless communication module, so that the first device and the first charging pile can exchange information by wireless communication. Thus, the first device and the first charging pile can be flexibly deployed in the charging network without the need to arrange a large number of wiring harnesses in the charging network, thereby effectively reducing the equipment deployment cost in the charging network. In addition, the first device can receive information about the first charging pile and / or information about the charging terminal connected to the first charging pile by wireless communication, so that the first device can subsequently analyze and process the information about the first charging pile and / or information about the charging terminal connected to the first charging pile.

[0058] It should be noted that the charging network in the embodiments of the present application can be applied to vehicle-to-everything (V2X) networks, long-term evolution-vehicle (LTE-V) networks, and vehicle-to-vehicle (V2V) networks. For example, it can be applied to vehicles or other devices that require charging. These other devices include, but are not limited to, robots, aircraft, ships, intelligent transportation equipment, smart home devices, and robots.

[0059] It should be noted that, in the embodiments of the present application, "at least one" refers to one or more, and "more" refers to two or more. "And / or" describes the association relationship of associated objects, indicating that three relationships may exist. For example, A and / or B can represent: the existence of A alone, the existence of A and B at the same time, and the existence of B alone, where A and B can be singular or plural. The character " / " generally indicates that the previous and next associated objects are in an "or" relationship. "At least one of the following items" or similar expressions refers to any combination of these items, including any combination of single items or plural items. For example, at least one of a, b, or c can represent: a, b, c, a and b, a and c, b and c, or a and b and c, where a, b, c can be single or multiple.

[0060] Furthermore, unless otherwise specified, ordinal numbers such as "first" and "second" in the embodiments of this application are used to distinguish between multiple objects and are not used to define the priority or importance of multiple objects. For example, "first message" and "second message" are only used to distinguish different messages, and do not indicate a difference in priority or importance between the two messages.

[0061] For ease of understanding, the following is an introduction with reference to the accompanying drawings and embodiments.

[0062] Figure 3 shows one schematic diagram of a charging network provided in an embodiment of the present application. In Figure 3, the charging network includes multiple charging piles and a first device.

[0063] The first device may be a target charging pile or a station controller. The communication quality of the target charging pile meets a preset indicator, which may include but is not limited to at least one of a failure rate, a packet loss rate, and a channel quality. By using the target charging pile in the charging network as the first device, there is no need to set up a separate station controller in the charging network, and the target charging pile can realize information collection and management of other charging piles in the charging network. Alternatively, a station controller is set up in the charging network and used as the first device, so that the station controller can realize information collection and management of the charging piles in the charging network, and the computing power resources of the station controller are relatively large. When the number of charging piles in the charging network is large, the station controller can still realize information management and control of all charging piles.

[0064] In Figure 3, the first device includes a wireless communication module 1, and multiple charging piles are taken as examples of charging piles 1 to 3. Charging pile 1 includes a wireless communication module 2, which can send message 1 to wireless communication module 1. Message 1 includes information about charging pile 1 and / or information about the charging terminal connected to charging pile 1. Accordingly, wireless communication module 1 receives message 1 from wireless communication module 2. Charging pile 2 includes a wireless communication module 3, which can send message 2 to wireless communication module 1. Message 2 includes information about charging pile 2 and / or information about the charging terminal connected to charging pile 2. Accordingly, wireless communication module 1 receives message 2 from wireless communication module 3. Charging pile 3 includes a wireless communication module 4, which can send message 3 to wireless communication module 1. Message 3 includes information about charging pile 3 and / or information about the charging terminal connected to charging pile 3. Accordingly, wireless communication module 1 receives message 3 from wireless communication module 4.

[0065] Among them, the wireless communication module 1 has a wireless long-distance communication function and a wireless short-distance communication function. The long-distance communication function can be achieved through cellular networks such as GPRS / CDMA, 3G, 4G, 5G, 6G, or long-distance global positioning system communication networks, and the short-distance communication function can be achieved through technologies such as Bluetooth, WiFi, or star flash communication. At least one of the wireless communication modules 2-4 can also have a long-distance communication function and a wireless short-distance communication function. Therefore, when the wireless communication module 1 is close to one or more of the wireless communication modules 2-4, the wireless communication module 1 can communicate with the one or more through the wireless short-distance communication network. Alternatively, when the wireless communication module 1 is far away from one or more of the wireless communication modules 2-4, the wireless communication module 1 can communicate with the one or more through the wireless long-distance communication network.

[0066] Among them, the information of any one of the charging piles 1 to 3 may include but is not limited to at least one of the charging voltage, charging current, charging power, temperature, insulation status, identification, or software version. The charging terminal (i.e., charging equipment) can be, for example, a robot, a ship, a vehicle, an airplane, or other equipment that needs to be charged, and the embodiments of this application are not limited thereto. The information of the charging terminal may, for example, include at least one of the user information associated with the charging terminal (such as a vehicle identification number, the owner's contact information, etc.), the power information of the charging terminal, or the communication information of the battery management system. Among them, the communication information of the battery management system includes communication messages involved in related processes such as physical connection, low voltage assistance, charging handshake, charging parameter configuration, and charging stage.

[0067] FIG4A shows a second schematic diagram of a charging network provided by an embodiment of the present application. In FIG4A , the first device may further include a control module, which may generate a control instruction based on the first message, and the control instruction is used to instruct the first charging pile (e.g., one or more of charging piles 1 to 3) to perform a first operation; wherein the first operation may include at least one of the following: adjusting charging parameters, payment operations, adjusting the thermal management system, fault diagnosis, alarm, reset, or OTA upgrade; accordingly, wireless communication module 1 may also send a control instruction to one or more of wireless communication modules 2 to 4, and accordingly, one or more of wireless communication modules 2 to 4 receive the control instruction. In this way, the first charging pile can perform the corresponding first operation.

[0068] For example, the first charging pile can adjust the charging parameters (e.g., charging power, charging voltage, charging current, etc.) of the first charging pile based on the control instructions, thereby making the charging parameter allocation of the first charging pile more reasonable. For another example, if the first charging pile is integrated with a billing system, the first charging pile can implement payment operations based on the control instructions. For another example, the first charging pile can also adjust the thermal management system of the first charging pile based on the control instructions to ensure the battery performance of the charging pile and improve the safety of the first charging pile. For another example, the first charging pile can also implement fault diagnosis based on the control instructions, allowing the first charging pile to promptly detect faults and respond to them in a timely manner. For another example, the first charging pile can also issue an alarm based on the control instructions, allowing the user to promptly inspect and maintain the first charging pile. For another example, the first charging pile can also reset based on the control instructions to implement certain fault repair functions (e.g., restarting the rectifier power outage, restarting the wireless communication module, restarting the power module, or restarting the main control). For another example, the first charging pile can also implement OTA upgrades based on the control instructions, which can complete functions such as power control and distribution unit program upgrades, charging control unit program upgrades, billing control unit program upgrades, and main control resets.

[0069] Among them, the above-mentioned control module can flexibly control or allocate the charging power of the first charging pile (for example, one or more of charging piles 1 to charging pile 3) according to the charging status of all charging piles in the entire charging network (for example, the number of charging terminals connected to each charging pile) and / or the power distribution status of energy equipment (for example, the power consumption of power grid equipment), so that the charging power in the entire charging network can be reasonably distributed. For example, if charging pile 1 has a large number of charging terminals connected to it, a higher charging power can be allocated to charging pile 1, and if charging pile 2 has a small number of charging terminals connected to it, a lower charging power can be allocated to charging pile 1.

[0070] Optionally, the control module can also control the prompt device to output the alarm information of charging pile 1 based on message 1. Similarly, the control module can also control the prompt device to output the alarm information of charging pile 2 based on message 2. The control module can also control the prompt device to output the alarm information of charging pile 3 based on message 3. Among them, the prompt device may include but is not limited to at least one of a voice device, a photoelectric device, or a display device. For example, the prompt device can be at least one of a tablet computer, a laptop computer, a PDA, a desktop computer, headphones, speakers, wearable devices (such as smart watches, smart bracelets, pedometers, etc.), virtual reality (VR) devices, or mobile phones. Accordingly, the alarm information can be at least one of a voice message, a text message, or a picture message. In this design, the first device controls the prompt device to output the corresponding alarm information, so that the user can promptly inspect and maintain one or more faults of charging piles 1-charging piles 3.

[0071] In one possible implementation, the information about the charging terminals connected to charging piles 1 through 3 includes information about the battery management system in the charging terminals. Furthermore, the control module can control the prompt device to output charging recommendation information for the charging terminals based on the information from the battery management system in the charging terminals. For example, taking a vehicle as an example, the control module can analyze the information from the vehicle's battery management system to recommend charging pile information for the vehicle.

[0072] Figure 4B shows a third schematic diagram of a charging network provided by an embodiment of the present application. In Figure 4B , the charging network may also include a server, which may be, for example, a cloud server, which may also be implemented as a virtual machine. The server can provide services such as device management, operation and maintenance management, scheduling management, and remote control for the charging network.

[0073] In a possible implementation, the wireless communication module 1 can also send messages 1-3 to the server. Message 1 includes information about the charging pile 1 and / or the charging terminal connected to the charging pile 1, message 2 includes information about the charging pile 2 and / or the charging terminal connected to the charging pile 2, and message 3 includes information about the charging pile 3 and / or the charging terminal connected to the charging pile 3. In this way, the server can store the information about the charging piles 1-3 and / or the charging terminals connected to the charging piles 1-3, and perform traceability analysis on the charging data of the charging piles 1-3 and / or the charging terminals connected to the charging piles 1-3, which helps to manage and maintain the charging network.

[0074] As can be seen from the foregoing description, the wireless communication module 1 has a wireless long-distance communication function. When the server and the first device are close together, the wireless communication module 1 can communicate with the server via a wireless short-distance communication network. Alternatively, when the server and the first device are far apart, the wireless communication module 1 can communicate with the server via a wireless long-distance communication network.

[0075] In another possible embodiment, the control module may further process messages 1-3 to obtain processed messages 1-3; and the first wireless communication module may further transmit the processed messages 1-3 to the server. Messages 1-3 include information about charging piles 1-3 and / or information about charging terminals connected to them. For example, the control module may perform fault diagnosis on charging piles 1-3 based on their information. If any of them fails, the control module may transmit the information about the failed charging pile to the server. For another example, the control module may perform fault diagnosis on the charging terminals connected to them based on their information. If any of them fails, the control module may transmit the information about the failed charging terminal to the server. This allows the server to store only critical data from the charging network, reducing the memory occupied by the server's stored charging network-related data.

[0076] FIG4C shows a fourth schematic diagram of a charging network provided in an embodiment of the present application. In FIG4C , the above-mentioned charging network may also include energy equipment; the energy equipment in FIG4C takes one energy equipment as an example. In other embodiments, the charging network may also include more energy equipment. Among them, the energy equipment may include, but is not limited to, one or more of the following: power grid equipment, energy storage system-related equipment, photovoltaic system-related equipment, wind power system-related equipment, or energy management system-related equipment. Among them, the power grid equipment may include inverter equipment, transformer equipment, power distribution equipment, etc. The energy storage system-related equipment may include energy storage transformers, batteries, etc. The wind power system-related equipment may include generators, wind power generation equipment, wind power generation equipment, etc. The photovoltaic system-related equipment includes photovoltaic modules, transformers, inverters, etc. The energy management system-related equipment may include energy control equipment, energy scheduling equipment, etc.

[0077] Among them, one or more of the power grid equipment, energy storage system, photovoltaic system, and wind power system can be electrically connected or communicatively connected to multiple charging piles in the charging network to provide power to the charging piles. Furthermore, one or more of the power grid equipment, energy storage system, photovoltaic system, and wind power system can wirelessly communicate with the first device and report corresponding information to the first device. As shown in Figure 4C, the energy device includes a wireless communication module 5, which can send a message 4 containing information about the energy device to the wireless communication module 1 in the first device; correspondingly, the wireless communication module 2 can receive the message 4 from the wireless communication module 5.

[0078] The energy device information may include, but is not limited to, at least one of voltage information, current information, power information, temperature information, thermal management system data (such as coolant temperature and flow rate), insulation status information, internal resistance, state of charge (SOC), battery state of health (SOH), light intensity data, wind speed, failure warnings, or alarm information. For example, when the energy device is a power grid device, the energy device information may include power data of the power distribution facilities in the power grid device, power grid dispatch data, inverter data, transformer capacity, etc. For another example, when the energy device is equipment related to an energy storage system, the energy device information may include the maximum output power of the energy storage system; for another example, when the energy device is equipment related to a photovoltaic system, the energy device information may include the maximum output power of the photovoltaic module; for another example, when the energy device is equipment related to a wind power system, the energy device information may include power data corresponding to the generator, wind turbine, or wind power generation equipment; for another example, when the energy device is equipment related to an energy management system, the energy device information may include electricity usage data of a smart meter.

[0079] Furthermore, the wireless communication module 2 can also send the information of the energy device to the server, so that the server can manage the information of the energy device.

[0080] In an embodiment of the present application, when the communication quality of the target charging pile does not meet the preset indicator, it is necessary to determine a new target charging pile in the charging network.

[0081] In one scenario, a new target charging pile can be determined in the charging network based on pre-configured information. For example, if the pre-configured information indicates that charging piles 1 and 2 in the charging network can be used as target charging piles, and if the communication quality of the current target charging pile does not meet the preset criteria, the charging pile that meets the preset criteria between charging piles 1 and 2 can be used as the new target charging pile.

[0082] In another scenario, the target charging pile can be determined based on a flexible networking approach for multiple charging piles. For example, the current target charging pile can send an instruction message to charging piles whose communication quality meets preset criteria, indicating that one charging pile will be the new target charging pile. In another example, any charging pile whose communication quality meets preset criteria can send a broadcast message to all charging piles in the charging network, indicating that the charging pile will be the new target charging pile.

[0083] In the embodiments of this application, the charging network can be deployed in a variety of ways, such as star networks, tree networks, and mesh networks. Figures 3-4C above only illustrate star networks, which offer a simpler deployment design and lower network latency. The following describes tree networks and mesh networks with reference to specific figures.

[0084] Figure 5 shows a tree-shaped charging network, which includes charging piles 1 to 9. Charging pile 1 includes a wireless communication module 2, charging pile 2 includes a wireless communication module 3, charging pile 3 includes a wireless communication module 4, charging pile 4 includes a wireless communication module 6, charging pile 5 includes a wireless communication module 7, charging pile 6 includes a wireless communication module 8, charging pile 7 includes a wireless communication module 9, charging pile 8 includes a wireless communication module 10, and charging pile 9 includes a wireless communication module 11; charging pile 1 can receive information about charging piles 4 and 5 and information about charging terminals connected to charging piles 4 and 5 from the wireless communication module 2, and transmit the information about charging piles 4 and 5 and information about charging terminals connected to charging piles 4 and 5 to charging piles 5. The wireless communication module 1 can also receive the information of charging pile 4-charging pile 9 and the information of the charging terminal connected to charging pile 4-charging pile 9 to the server.

[0085] When there are many charging stations in the charging network, a tree-shaped charging network as shown in Figure 5 can be used, so that some charging piles in the charging network can serve as branch nodes. These branch nodes can collect information about the charging piles connected to them and send it to the first device. In this way, the communication efficiency of the entire charging network can be effectively improved.

[0086] Figure 6 shows a meshed charging network, which includes charging piles 1-4. Charging pile 1 includes a wireless communication module 2, charging pile 2 includes a wireless communication module 3, charging pile 3 includes a wireless communication module 4, and charging pile 4 includes a wireless communication module 5. Any two of charging piles 1-4 can establish a wireless communication connection and send their information to each other. Optionally, wireless communication module 1 can also send this information to a server. In a meshed charging network, wireless communication can be established between any two charging piles, allowing the charging network to flexibly select a communication path based on the communication effect.

[0087] The charging piles in Figures 3, 4A-4C, 5, and 6 can be integrated charging piles and / or split charging piles. Accordingly, when the target charging pile is a split charging pile, the target charging pile includes a target charging host and a target charging pile terminal, and the target charging host includes a wireless communication module 1. The target charging host and the target charging pile terminal can communicate with each other in a wireless communication mode or a wired communication mode. The target charging pile terminal can be, for example, a charging pile, a charging induction base, etc. The target charging pile terminal can be electrically connected and / or communicatively connected to the charging terminal to realize related services such as charging and charging the charging terminal. In addition, other charging piles in the charging network that wirelessly communicate with the target charging pile can also be integrated charging piles and / or split charging piles.

[0088] Figure 7 shows another charging network provided by an embodiment of the present application, which includes a charging host 1, a charging host 2, a charging host 3, a charging pile terminal 1, a charging pile terminal 2, a charging pile terminal 3, a charging pile terminal 4, a charging pile terminal 5, and a charging pile terminal 6; wherein, the charging host 1 includes a wireless communication module 2, the charging host 2 includes a wireless communication module 3, the charging host 3 includes a wireless communication module 4, the charging pile terminal 1 includes a wireless communication module 6, the charging pile terminal 2 includes a wireless communication module 7, the charging pile terminal 3 includes a wireless communication module 8, the charging pile terminal 4 includes a wireless communication module 9, the charging pile terminal 5 includes a wireless communication module 10, and the charging pile terminal 6 includes a wireless communication module 11.

[0089] Among them, the wireless communication module 2 can receive information about the charging pile terminal 1 and the charging terminal connected to the charging pile terminal 1 from the wireless communication module 6, and the wireless communication module 2 can receive information about the charging pile terminal 2 and the charging terminal connected to the charging pile terminal 2 from the wireless communication module 7, and send the information about the charging pile terminal 1 and the charging pile terminal 2, as well as the information about the charging terminal connected to the charging pile terminal 1 and the charging pile terminal 2 to the first device.

[0091] Similarly, the wireless communication module 4 can receive information about the charging pile terminal 5 and the charging terminal connected to the charging pile terminal 5 from the wireless communication module 10, and the wireless communication module 3 can receive information about the charging pile terminal 6 and the charging terminal connected to the charging pile terminal 6 from the wireless communication module 11, and send the information about the charging pile terminal 5 and the charging pile terminal 6, as well as the information about the charging terminal connected to the charging pile terminal 5 and the charging pile terminal 6 to the first device.

[0092] Optionally, the first device may also send the received information of the charging host 1 -charging host 3 , the information of the charging pile terminal 1 -charging pile terminal 6 , and the information of the charging terminal connected to the charging pile terminal 1 -charging pile terminal 6 to the server.

[0093] In an embodiment of the present application, in order to improve the reliability of the communication network, the first device can implement anti-interference transmission through at least one of the following methods: frequency hopping transmission, random avoidance, retransmission mechanism, polarization code encoding, carrier monitoring, time division multiplexing transmission mechanism, frequency division multiplexing transmission mechanism; and / or, other charging piles in the charging network that wirelessly communicate with the first device (for example, charging piles 1-charging piles 3 shown in Figure 3) can implement anti-interference transmission through at least one of the following methods: frequency hopping transmission, random avoidance, retransmission mechanism, polarization code encoding, carrier monitoring, time division multiplexing transmission mechanism, frequency division multiplexing transmission mechanism.

[0094] In the embodiment of the present application, frequency hopping transmission is implemented in the charging network, which may include but is not limited to the following implementations:

[0095] In implementation mode 1, the transmission parameters corresponding to the first device and other devices in the charging network other than the first device are orthogonal, and the orthogonality of the wireless channel transmission parameters is achieved by at least one of the following: the transmission frequency resources corresponding to the first device and other devices in the charging network other than the first device are different; the transmission frequency resources and frequency hopping patterns corresponding to the first device and other devices in the charging network other than the first device are the same, but the frequency hopping starting points are different; the first device and other devices in the charging network other than the first device exchange transmission parameters. In this way, the transmission parameters corresponding to the first device and other devices in the charging network other than the first device are orthogonal, and the wireless channel transmission parameters are orthogonal, so that information transmission in the charging network does not interfere with each other, thereby effectively improving the communication reliability of the charging network. Among them, the transmission parameters may include but are not limited to at least one of the following: frequency transmission resources, utilization of frequency transmission resources, or frequency hopping transmission parameters (such as frequency hopping pattern, or frequency hopping starting point, etc.).

[0096] In embodiment 2, multiple charging piles and at least one energy device in a charging network are divided into multiple groups. These groups include a first group and a second group. The frequency-hopping wireless channel transmission parameters corresponding to the first and second groups are orthogonal. This allows the frequency-hopping wireless channel transmission parameters corresponding to different groups to be orthogonal, thus achieving frequency-hopping transmission in the charging network.

[0097] Furthermore, in an embodiment of the present application, using one or more of random avoidance, retransmission mechanism, polar code encoding, carrier sensing, time division multiplexing transmission mechanism, or frequency division multiplexing transmission mechanism in the charging network can effectively improve the communication reliability of the charging network.

[0098] In an embodiment of the present application, taking into account the redundant backup of some information in the charging network, a wired communication connection may also exist between the first device and some charging piles in the charging network, and the wired communication connection is used to transmit information whose transmission reliability meets the first condition and / or the amount of transmission data meets the first threshold. In this way, information with high transmission reliability requirements (such as information on charging piles) can be transmitted by wired communication, and information with low transmission reliability requirements (such as control instructions) can be transmitted by wireless communication. In this way, data with high transmission reliability requirements and / or large transmission data volume (for example, charging power, charging voltage, current, temperature, fault, alarm, etc.) can be transmitted by wired communication. Data with low transmission reliability requirements and / or small transmission data volume (for example, thermal management system data, payment data, etc.) can be transmitted by wireless communication.
