Description

Technical Field

[0001] The present application relates to the field of communication technology, and in particular to a charging network, electronic equipment and a charging pile. Background Art

[0002] With the development of new energy vehicle technology, the market share of new energy vehicles is getting higher and higher, and the technology of new energy vehicles is becoming more and more mature, but the range anxiety and charging problems of new energy vehicles are still the pain points that consumers are concerned about. Therefore, it is necessary to build a large number of charging networks for users to charge new energy vehicles.

[0003] However, in the current charging network, most devices communicate via wired communication, which results in high communication deployment costs, poor flexibility, and difficulty in repair and maintenance. Figure 1 As shown, in a wired charging network, the charging piles need to communicate with network equipment (such as switches) through wired communication, and the charging piles need to communicate with each other through wired communication, resulting in many and complex wiring harnesses in the charging network. When arranging the charging piles, trenches need to be dug for wiring, which is costly. In addition, after the wiring in the charging network is poured with cement, it is difficult to maintain and repair it, and it is not friendly to later deletions or expansions and changes in communication networking methods.

[0004] It can be seen that the new energy vehicle industry currently lacks a low-cost, flexible and easy-to-maintain charging network. Summary of the invention

[0051] To facilitate understanding, some terms involved in the embodiments of the present application are first introduced below.

[0052] 1. An integrated charging pile combines the charging host and charging pile terminal (such as a charging gun, a charging induction base, etc.) in one device. Among them, an integrated charging pile can also integrate multiple functional modules such as DC fast charging, AC slow charging, charging management system, billing system, communication module, etc. into one machine 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 safety, reliability, easy operation, small footprint, and low energy consumption. It is suitable for public parking lots, commercial centers, office buildings, and other places that require a large number of charging facilities. Exemplarily, an integrated charging pile can be as follows Figure 2AAs shown, the integrated charging pile integrates a charging host and a charging pile terminal.

[0053] 2. Split charging piles, in which the charging host and charging pile terminal are independently set. The charger can provide stable, reliable and adjustable AC power and DC power 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.). Split charging piles can be flexibly arranged in various places, and are more suitable for occasions that require temporary installation or movement, such as roadside parking spaces, residential areas, logistics warehousing, etc. For example, the split charging pile can be as follows Figure 2B As shown, the split-type 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 and DC power for the charging pile terminals 1-3, and the charging pile terminals 1-3 can charge different charging terminals respectively.

[0054] 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 in a wireless communication manner, and then 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 in a wireless communication manner, 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.

[0055] It should be noted that the charging network in the embodiment of the present application can be applied to the Internet of Vehicles, such as vehicle to everything (V2X), long term evolution-vehicle (LTE-V), vehicle to vehicle (V2V), etc. For example, it can be applied to vehicles or other devices that need to be charged. The other devices include but are not limited to: robots, airplanes, ships, intelligent transportation equipment, smart home devices, robots, etc.

[0056] It should be noted that in the embodiments of the present application, "at least one" refers to one or more, and "more than one" 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: A exists alone, A and B exist at the same time, and B exists 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" or similar expressions refers to any combination of these items, including any combination of single 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.

[0057] Furthermore, unless otherwise specified, the ordinal numbers such as "first" and "second" mentioned in the embodiments of the present application are used to distinguish multiple objects, and are not used to limit the priority or importance of multiple objects. For example, the first message and the second message are only used to distinguish different messages, rather than indicating the difference in priority or importance of the two messages.

[0058] For ease of understanding, the present invention is described below with reference to the accompanying drawings and embodiments.

[0059] Figure 3 FIG. 1 shows one schematic diagram of a charging network provided in an embodiment of the present application. Figure 3 In the embodiment, the charging network includes a plurality of charging piles and a first device.

[0060] Among them, the first device may be a target charging pile or a station controller. Among them, the communication quality of the target charging pile meets the preset indicators, and the preset indicators may include but are not limited to at least one of the failure rate, packet loss rate, and channel quality. The target charging pile in the charging network is used as the first device, so that there is no need to set up a station controller separately 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 in the charging network, and the station controller is 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 large. When the number of charging piles in the charging network is large, the station controller can still realize information control of all charging piles.

[0061] exist Figure 3In the embodiment, the first device includes a wireless communication module 1, and multiple charging piles are taken as charging piles 1 to 3 as an example. Charging pile 1 includes a wireless communication module 2, and the wireless communication module 2 can send a message 1 to the wireless communication module 1, and the message 1 includes the information of the charging pile 1 and / or the information of the charging terminal connected to the charging pile 1. Accordingly, the wireless communication module 1 receives the message 1 from the wireless communication module 2. Charging pile 2 includes a wireless communication module 3, and the wireless communication module 3 can send a message 2 to the wireless communication module 1, and the message 2 includes the information of the charging pile 2 and / or the information of the charging terminal connected to the charging pile 2. Accordingly, the wireless communication module 1 receives the message 2 from the wireless communication module 3. Charging pile 3 includes a wireless communication module 4, and the wireless communication module 4 can send a message 3 to the wireless communication module 1, and the message 3 includes the information of the charging pile 3 and / or the information of the charging terminal connected to the charging pile 3. Accordingly, the wireless communication module 1 receives the message 3 from the wireless communication module 4.

[0062] 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 realized 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 realized through technologies such as Bluetooth, wifi, or star flash communication. At least one of the wireless communication modules 2-wireless communication modules 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-wireless communication modules 4, the wireless communication module 1 can communicate with the one or more through a 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-wireless communication modules 4, the wireless communication module 1 can communicate with the one or more through a wireless long-distance communication network.

[0063] Among them, the information of any one of the charging piles 1-3 may include but is not limited to at least one of the charging voltage, charging current, charging power, temperature, insulation state, 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, which is not limited in the embodiments of the present application. 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.

[0064] Figure 4A FIG2 shows a second schematic diagram of a charging network provided in an embodiment of the present application. Figure 4AIn the embodiment, the first device may further include a control module, which may generate a control instruction according to the first message, and the control instruction is used to instruct the first charging pile (for example, one or more of charging pile 1-charging pile 3) to perform a first operation; wherein the first operation may include at least one of the following: adjusting charging parameters, payment operation, adjusting thermal management system, fault diagnosis, alarm, reset, or OTA upgrade; accordingly, the wireless communication module 1 may also send a control instruction to one or more of the wireless communication modules 2-wireless communication modules 4, and accordingly, one or more of the wireless communication modules 2-wireless communication modules 4 receive the control instruction. In this way, the first charging pile may perform the corresponding first operation.

[0065] For example, the first charging pile can adjust the charging parameters (such as charging power, charging voltage, charging current, etc.) of the first charging pile according to the control instruction, so that the charging parameter distribution of the first charging pile is more reasonable. For another example, when the first charging pile integrates a billing system, the first charging pile can realize the payment operation according to the control instruction. For another example, the first charging pile can also adjust the thermal management system of the first charging pile according to the control instruction 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 realize fault diagnosis according to the control instruction, and the first charging pile can find the fault in time, and then the first charging pile can respond to the fault in time. For another example, the first charging pile can also alarm according to the control instruction, so that the user can repair and maintain the first charging pile in time. For another example, the first charging pile can also reset according to the control instruction to realize certain fault repair functions (for example, rectifier power off restart, wireless communication module restart, power module restart, or master control restart, etc.). For another example, the first charging pile can also realize OTA upgrades that can complete the power control and distribution unit program upgrade, charging control unit program upgrade, billing control unit program upgrade, master control reset and other functions according to the control instruction.

[0066] Among them, the above 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 piles 3) according to the charging conditions 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 conditions 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 allocated. For example, if the number of charging terminals connected to charging pile 1 is large, a higher charging power can be allocated to charging pile 1, and if the number of charging terminals connected to charging pile 2 is small, a lower charging power can be allocated to charging pile 1.

[0067] Optionally, the control module can also control the prompt device to output the alarm information of charging pile 1 according to message 1. Similarly, the control module can also control the prompt device to output the alarm information of charging pile 2 according to message 2. The control module can also control the prompt device to output the alarm information of charging pile 3 according to message 3. Among them, the prompt device may include but is not limited to at least one of a voice device, an optoelectronic device, or a display device. For example, the prompt device can be, for example, a tablet computer, a laptop computer, a PDA, a desktop computer, a headset, a stereo, a wearable device (such as a smart watch, a smart bracelet, a pedometer, etc.), a virtual reality (VR) device, or a mobile phone. Correspondingly, 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 in charging piles 1-charging piles 3.

[0068] In a possible implementation, the information of the charging terminal connected to the charging piles 1 to 3 includes the information of the battery management system in the charging terminal; and the control module can also control the prompt device to output the charging recommendation information of the charging terminal according to the information of the battery management system in the charging terminal. For example, the charging terminal takes a vehicle as an example, and the control module can recommend charging pile information for the vehicle by analyzing the information of the battery management system of the vehicle.

[0069] Figure 4B FIG3 shows a third schematic diagram of a charging network provided in an embodiment of the present application. Figure 4B In the above charging network, a server may also be included. The server may be, for example, a cloud server, which may also be implemented by a virtual machine. The server may implement services such as equipment management, operation and maintenance management, scheduling management, and remote control of the charging network.

[0070] In a possible implementation, the wireless communication module 1 can also send message 1-message 3 to the server. Among them, message 1 includes information of charging pile 1 and / or information of the charging terminal connected to charging pile 1, message 2 includes information of charging pile 2 and / or information of the charging terminal connected to charging pile 2, and message 3 includes information of charging pile 3 and / or information of the charging terminal connected to charging pile 3. In this way, the server can store the information of charging piles 1-charging piles 3 and / or the information of the charging terminals connected to charging piles 1-charging piles 3, and trace the charging data of charging piles 1-charging piles 3 and / or the charging terminals connected to charging piles 1-charging piles 3, which is helpful for the management and maintenance of the charging network.

[0071] As can be seen from the foregoing description, the wireless communication module 1 has a wireless long-distance communication function. When the server is close to the first device, the wireless communication module 1 can communicate with the server through a wireless short-distance communication network. Alternatively, when the server is far from the first device, the wireless communication module 1 can communicate with the server through a wireless long-distance communication network.

[0072] In another possible implementation, the control module may also process message 1-message 3 to obtain processed message 1-message 3; and then the first wireless communication module may also send the processed message 1-message 3 to the server. Among them, message 1-message 3 includes information of charging pile 1-charging pile 3 and / or information of charging terminal connected to charging pile 1-charging pile 3. For example, the control module may perform fault diagnosis on charging pile 1-charging pile 3 according to the information of charging pile 1-charging pile 3, and when one of the charging piles 1-charging pile 3 fails, the information of the faulty charging pile is sent to the server. For another example, the control module may perform fault diagnosis on the charging terminal connected to charging pile 1-charging pile 3 according to the information of the charging terminal connected to charging pile 1-charging pile 3, and when any charging terminal connected to charging pile 1-charging pile 3 fails, the information of the faulty 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 in the server.

[0073] Figure 4C FIG4 shows a fourth schematic diagram of a charging network provided in an embodiment of the present application. Figure 4C In the above charging network, energy equipment may also be included; Figure 4C The energy device in the example is an energy device. In other embodiments, the charging network may include more energy devices. Among them, the energy devices may include but are 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.

[0074] Among them, one or more of the power grid equipment, energy storage system, photovoltaic system, and wind power system can be electrically connected or communicated with multiple charging piles in the charging network to provide power for the charging piles. And 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. Figure 4C As shown, the energy device includes a wireless communication module 5, which can send a message 4 to the wireless communication module 1 in the first device, and the message 4 includes information of the energy device; correspondingly, the wireless communication module 2 can receive the message 4 from the wireless communication module 5.

[0075] The information of the energy device may include but is not limited to at least one of voltage information, current information, power information, temperature information, thermal management system data (coolant temperature and flow rate, etc.), insulation state information, internal resistance, state of charge (SOC), battery health state (SOH), light intensity data, wind speed, failure warning, or alarm information. For example, when the energy device is a power grid device, the information of the energy device may include power data of the power distribution facilities in the power grid device, power grid dispatching data, inverter data, transformer capacity, etc. For another example, when the energy device is a device related to an energy storage system, the information of the energy device may include the maximum output power of the energy storage system; for another example, when the energy device is a device related to a photovoltaic system, the information of the energy device may include the maximum output power of the photovoltaic module; for another example, when the energy device is a device related to a wind power system, the information of the energy device may include power data corresponding to the generator, wind power generation equipment, or wind power generation equipment; for another example, when the energy device is a device related to an energy management system, the information of the energy device may include power consumption data of a smart meter.

[0076] 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.

[0077] In the 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.

[0078] In one case, a new target charging pile can be determined in the charging network according to the pre-configuration information. For example, the pre-configuration information indicates that charging pile 1 and charging pile 2 in the charging network can be used as target charging piles. When the communication quality of the current target charging pile does not meet the preset index, the charging pile that meets the preset index between charging pile 1 and charging pile 2 can be used as the new target charging pile.

[0079] In another case, it can be determined based on the flexible networking mode of multiple charging piles. For example, the current target charging pile can send indication information to the charging piles whose communication quality meets the preset indicators to indicate a charging pile as the new target charging pile. For another example, any charging pile whose communication quality meets the preset indicators can send broadcast information to all charging piles in the charging network, and the broadcast information is used to indicate that any charging pile will be used as the new target charging pile.

[0082] When the number of chargers in the charging network is large, Figure 5 In the tree-shaped charging network, some charging piles in the charging network can be used 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.

Optionally, the wireless communication module 1 can also send the information to the server. Among them, in the mesh charging network, wireless communication can be carried out between any two charging piles, so that the charging network can flexibly select the communication path according to the communication effect.

In addition, other charging piles in the charging network that wirelessly communicate with the target charging pile may also be integrated charging piles and / or split charging piles.
