[0002] With the development of electric vehicles, the demand for charging piles or charging stations is increasing daily. Currently, charging piles or charging stations mainly have two structures: integrated and split. The integrated structure integrates power module control and charging control into a single cabinet, allowing for unified control by a single controller. The split structure places functional control in the module cabinet, while charging control and business settlement are handled in the terminal gun cabinet. However, both solutions require customized development. All controllers are interconnected and strongly coupled with the application scenario and internal electrical components, necessitating the development of different products for different application scenarios. This results in long development cycles, high costs, and hinders the rapid deployment and operation and maintenance of charging piles or charging stations. Summary of the Invention

[0050] Exemplary embodiments of the present disclosure will now be described in more detail with reference to the accompanying drawings. While exemplary embodiments of the present disclosure are shown in the drawings, it should be understood that the present disclosure may be implemented in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the disclosure to those skilled in the art.

[0051] To solve or at least partially solve the above problems, embodiments of the present invention propose a charging control system.

[0052] Figure 1 A schematic structural block diagram of a charging control system 100 according to an embodiment of the present invention is shown. See also Figure 1As shown, the charging control system 100 adopts a hierarchical control architecture and generally includes at least one charging control module 110 and at least one power control module 120. The hierarchical control architecture of the charging control system 100 may include at least a charging management layer and a power management layer, with the power management layer being the upper layer of the charging management layer. The at least one charging control module 110 is located in the charging management layer, and each charging control module 110 includes a charging management unit (CMU) 111, which is an electronic control unit (ECU). The at least one power control module 120 is located in the power management layer, and each power control module 120 includes a power management unit (PMU) 121, which is an electronic control unit, and a power distribution unit (PDU) 122 connected to the power management unit 121. The power management unit 121 in each power control module 120 is connected to the charging management unit 111 in at least one charging control module 110. Each charging management unit 111 can be configured to connect to at least one vehicle 130 to be charged, receive charging requests from the vehicle 130, and send the charging requests to the power management unit 121 connected to it. The power management unit 121, according to scheduling instructions and the received charging requests, controls the power allocation unit 122 connected to it to allocate power to the charging management unit 111, and monitors the charging management unit 111's use of the allocated power to charge the vehicle 130, thereby completing the charging power control. It should be noted that... Figure 1 The number of components shown is merely illustrative and does not limit the invention.

[0053] The charging control system 100 provided in this embodiment of the invention adopts a hierarchical control architecture and modular design. The network architecture of the charging control system 100 includes a charging management layer and a power management layer, and the modular architecture includes a charging control module 110 and a power control module 120. This approach decouples the modules, achieving complete decoupling of the charging control system 100 in terms of function, electrical layout, and physical space. This allows for rapid deployment and combination according to application scenarios, saving development time and costs.

[0054] In a further embodiment, each power management unit 121 can connect to the cloud (e.g., wireless or wired Ethernet) and interact directly with it. The power management unit 121 receives the scheduling command from the cloud, collects the status information of the charging control system 100, and uploads it to the cloud for service settlement. In this embodiment, the status information of the charging control system 100 includes the working status information of each unit (specifically, power management unit 121, power distribution unit 122, charging management unit 111, etc.) as well as charging control and service information (such as charging time, charging power consumption, charging user information, etc.).

[0055] Figure 2 A schematic structural block diagram of a charging control system 100 according to another embodiment of the present invention is shown. It should be noted that... Figure 2 The number of components shown is merely illustrative and does not limit the invention.

[0056] In one embodiment of the present invention, see Figure 2 As shown, the network architecture of the charging control system 100 may further include a station monitoring layer, which is the upper layer of the power management layer. The charging control system 100 may also include a service control module 140. The service control module 140 is located in the station monitoring layer and includes a station monitoring unit (SMU) 141, which serves as an electronic control unit. The station monitoring unit 141 is connected to the power management unit 121 in each power control module 120, and is configured to issue scheduling commands to the power management unit 121 and collect the status information of the charging control system 100. In this embodiment, the status information of the charging control system 100 includes the working status information of each unit (specifically, the station monitoring unit 141, power management unit 121, power allocation unit 122, charging management unit 111, etc.) as well as charging control and service information.

[0057] In a further embodiment, the site monitoring unit 141 can be connected to the cloud (e.g., wireless or wired Ethernet). When the site monitoring unit 141 is normally connected to the cloud, it receives the scheduling instructions from the cloud for site management and uploads the collected status information of the charging control system 100 to the cloud for business settlement.

[0058] In some embodiments, when the site monitoring unit 141 loses connection with the cloud, the site monitoring unit 141 can autonomously manage the site (at this time, the site monitoring unit 141 autonomously generates scheduling instructions) and store the collected status information of the charging control system 100 locally until the connection with the cloud is re-established before uploading the status information of the charging control system 100.

[0059] In other embodiments, when the power management unit 121 loses connection with the station monitoring unit 141, the power management unit 121 can also autonomously control the charging power to complete vehicle charging and record charging control and service information until it re-establishes connection with the station monitoring unit 141 before reporting the charging control and service information to the station monitoring unit 141.

[0060] The above embodiments can ensure that the charging control system 100 continues to operate normally when a partial connection failure occurs, and avoid data loss.

[0061] In an optional embodiment, see also: Figure 2 As shown, the charging control system 100 may further include at least one energy storage control module 150 at the power management layer. Each energy storage control module 150 includes an energy management unit (EMU) 151, which serves as an electronic control unit, and an energy storage device 152 (such as a battery) connected to the energy management unit 151. In the absence of a site monitoring layer, the energy management unit 151 may be connected to each power management unit 121 and configured to collaboratively control the energy storage device 152 for energy storage and discharge, thereby functioning as a power bank and energy balancer for the entire charging pile / station. In the case where the charging control system 100 includes a site monitoring layer, the energy management unit 151 can be connected to each power management unit 121 and the site monitoring unit 141 respectively. It is configured to control the energy storage device 152 to store and discharge energy under the coordination and control of the site monitoring unit 141 and / or in coordination with each power management unit 121, thereby acting as a power bank and energy balancer for the entire charging pile / station. Furthermore, it should be noted that when the charging control system 100 includes an energy storage control module 150, the status information of the charging control system 100 mentioned above, including the operating status information of each unit, also includes the operating status information of the energy management unit 151.

[0062] In an optional embodiment, see also: Figure 2 As shown, each power control module 120 also includes multiple power modules 123. Under the control of the power management unit 121, the power distribution unit 122 executes the switching logic of the power modules 123 to distribute power to the charging management unit 111.

[0063] In a preferred embodiment of the present invention, each electronic control unit (ECU) of the charging control system 100 (specifically, such as the site monitoring unit 141, power management unit 121, energy management unit 151, and charging management unit 111) can operate in at least one of the following modes: upper-level dispatch control mode, autonomous mode, and same-level collaborative mode. Upper-level dispatch control mode refers to operation based on the dispatch control of the upper-level ECU. For example, the power management unit 121 or energy management unit 151 in the power management layer operates under the dispatch control of the site monitoring unit 141 in the site monitoring layer, or the charging management unit 111 in the charging management layer operates under the dispatch control of the power management unit 121. Autonomous mode refers to the ECU operating autonomously. For example, the site monitoring unit 141 autonomously performs site management when it loses connection with the cloud. The same-layer collaborative mode refers to the electronic control unit (ECU) operating collaboratively with other ECUs on the same layer. For example, energy management unit 151 can operate collaboratively with power management unit 121, or a power management unit 121 can operate collaboratively with energy management unit 151 or other power management units 121. Under normal operation of the charging control system 100, the above three operating modes coexist, and the priority of upper-layer dispatch control mode, same-layer collaborative mode, and autonomous mode decreases sequentially, that is, the priority order is: upper-layer dispatch control mode > same-layer collaborative mode > autonomous mode.

[0064] In this embodiment, the modules of the charging control system 100 adopt a combination of single master control (i.e., control is dispatched through a single site monitoring unit 141) and multi-master automatic coordination (i.e., multiple electronic control units on the same level operate in coordination), which can work together or work independently, thereby enhancing system availability.

[0065] In some embodiments, if any power management unit 121 malfunctions, it can automatically disconnect from the charging control system 100 and cease controlling the power distribution unit 122 and the charging management unit 111 connected to it. That is, the power control module 120 containing the malfunctioning power management unit 121 will automatically disconnect from the control system 100.

[0066] In some embodiments, if any charging management unit 111 malfunctions, it can automatically disconnect from the control of the power management unit 121 connected to it and stop charging. That is to say, the charging control module 110 containing the malfunctioning charging management unit 111 will automatically disconnect from the control system 100.

[0067] In some embodiments, if any energy management unit 151 malfunctions, it can automatically disconnect from the charging control system 100 and cease controlling the energy storage device 152 connected to it. That is, the energy storage control module 150 containing the malfunctioning energy management unit 151 will automatically disconnect from the control system 100.

[0068] This design allows any module to automatically disconnect from the control system 100 without affecting the operation of other modules, enhancing system robustness and facilitating maintenance. Furthermore, repaired faulty modules or newly added modules can automatically rejoin the control system 100, achieving "plug and play."

[0069] Figure 3 A hierarchical architecture diagram of a charging control system 100 according to an embodiment of the present invention is shown. Figure 4 A schematic diagram of the composition structure of a charging control system 100 according to an embodiment of the present invention is shown below. Figure 3 and Figure 4 A more detailed description will be given of a specific embodiment of the charging control system 100 of the present invention.

[0070] like Figure 3 As shown, the charging control system 100 in this embodiment is mainly divided into three layers: the site monitoring layer, the power management layer, and the charging management layer. The site monitoring layer is implemented by the site monitoring unit 141, which mainly manages the entire site (e.g., charging scheduling, business settlement, environmental monitoring, etc.). The site monitoring unit 141 communicates with the cloud platform (i.e., the cloud) through an OTA (Over-the-Air) gateway. The cloud platform can realize OTA upgrades, parameter distribution, command distribution, information monitoring, data processing, and other functions. The cloud platform can also further communicate with a client APP to achieve human-computer interaction.

[0071] The site monitoring unit 141 can also provide other additional services. For example, the charging control system 100 can be installed at the charging site, which may include camera equipment, a ground lock system, and an access control system. The site monitoring unit 141 can be connected to the camera equipment, the ground lock system, and the access control system respectively, and can acquire images from the camera equipment for environmental monitoring, and control the ground lock system and the access control system.

[0072] The power management layer consists of multiple power management units 121, power distribution units 122, and energy management units 151. Power management units 121 can communicate with the site monitoring unit 141 via an OTA gateway, primarily implementing functions such as power management, thermal management, electrical monitoring, and environmental monitoring. Specifically, in electrical monitoring, power management units 121 can respond to charging requests from charging management units 111 to monitor voltage insulation. Furthermore, power management units 121 can perform fault management when a fault occurs, enabling automatic disconnection from the control system 100 after a fault. Power distribution units 122 primarily implement power switching logic control and power distribution functions. Energy management units 151 primarily implement energy storage management, energy distribution, and environmental monitoring functions.

[0073] The charging management layer consists of multiple charging management units 111, which mainly realize functions such as communication with the vehicle 130 to be charged (i.e., vehicle-side interaction), charging control, liquid cooling gun cooling system control (i.e., liquid cooling control), and human-machine interaction. When the charging management unit 111 malfunctions, it can also perform fault management to automatically disconnect from the control system 100 after a fault.

[0074] ECUs on the same level can be controlled by upper-level ECUs, operate autonomously, or coordinate with other ECUs on the same level. Under normal operation, these three modes coexist, with the following priority: upper-level ECU control > coordinated operation of ECUs on the same level > autonomous operation. If an ECU loses control from an upper-level ECU, it will automatically switch to coordinated or autonomous operation. The power management unit 121 in the power management layer is also responsible for controlling the power distribution unit 122 to achieve all power management functions. The energy management unit 151 controls the battery storage cabinet and, under the control of the upper-level station monitoring unit 141 and in coordination with the power management unit 121 on the same level, achieves energy storage and discharge, providing the entire charging pile / station with power bank and energy balancer functions.

[0075] Figure 4 The composition structure of the charging control system 100 in this embodiment is described in more detail. The service control module 140 is installed in the power distribution cabinet (or low-voltage cabinet), each power control module 120 is installed in the corresponding module cabinet, the energy control module is installed in the energy storage cabinet, and each charging control module 110 is installed in the corresponding charging gun cabinet.

[0076] The site monitoring unit (SMU) is responsible for the overall site management. Upstream, it communicates with the cloud, uploading status information of the charging control system 100 and receiving cloud scheduling instructions. Downstream, it connects to the power management unit (PMU) in the module cabinet and the energy management unit (EMU) in the energy storage cabinet via Ethernet or CAN (Controller Area Network) buses, collecting the working status information of each PMU and EMU and performing scheduling control (such as energy charging and discharging control of the energy storage cabinet, power distribution control of each module cabinet, etc.).

[0077] The PMU (Power Management Unit) in the module cabinet is the core component of the charging control system 100. It connects upwards to the site monitoring unit (SMU) and other PMUs / EMUs via CAN or Ethernet networks to report operational status information, receive scheduling commands, or collaborate with other PMUs / EMUs for control. The PMU has two downward-facing CAN networks: one connects to the power modules and power distribution units (PDUs) within the module cabinet for power allocation scheduling and module switching control; the other connects to the charging management unit (CMU) in the charging gun cabinet for interactive control of the charging process. The PMU also collects information such as voltage and insulation data (e.g., information from insulation detectors) via RS485 buses, providing necessary information for power control, charging interaction, and service settlement. The CMU in the charging gun cabinet interacts with the vehicle for charging control and interacts with the PMU to complete the charging process, while also providing necessary human-machine interaction (e.g., information display), charging gun cabinet monitoring, and liquid-cooled gun thermal management functions.

[0078] like Figure 4 As shown, there can be multiple charging gun cabinets and module cabinets. A charging station can be configured with one or more energy storage cabinets and one or more module cabinets. A module cabinet can connect to one or more charging gun cabinets, and a charging gun cabinet can connect to one or more vehicles (specifically electric vehicles) to be charged. Charging gun cabinets, module cabinets, and energy storage cabinets can be added or removed according to the needs of the charging station. The charging management unit (CMU) of each charging gun cabinet is controlled by the PMU of the module cabinet and requests the PMU to output the required power to achieve charging after interacting with the vehicle. The PMU monitors the operation of the CMU and responds to the CMU's requests to complete insulation monitoring, power allocation, etc., and finally realizes the charging function. At the same time, the PMU also needs to comprehensively control the PDU and each power module according to the requests of each CMU, the scheduling instructions of the SMU, and the status of other PMUs and EMUs, so as to allocate the power of each power module to each charging gun cabinet, and then transfer the energy to the vehicle's BMS (Battery Management System) through the charging gun cabinet.

[0079] If the SMU and the cloud lose communication, the SMU will directly manage the site and complete all charging control and business information storage. It will upload the relevant charging control and business information and complete business settlement after reconnecting to the cloud. Similarly, if the PMU loses connection with the SMU, each PMU can control the charging power to complete charging and record the charging data. The recorded charging data will be reported after successfully reconnecting to the SMU. If a PMU in a module cabinet or an EMU in an energy storage cabinet malfunctions, it will automatically disconnect from the system and stop power control for that module cabinet, without affecting the operation of other cabinets. If the CMU in a gun cabinet malfunctions, that gun cabinet will automatically disconnect from the control system and stop charging, without affecting the charging of other gun cabinets.

[0080] In this embodiment, through hierarchical and modular design, each module can operate in combination or independently. From the lower layer to the upper layer, there are multiple independent vehicle charging connections, multiple independent gun cabinets, and multiple independent module cabinets. Adding, deleting, or damaging any module at the same level will not affect the operation of other modules. For different scenarios, modules can be quickly added, removed, or freely combined to achieve rapid deployment, greatly enhancing the availability and robustness of the system.

[0081] Based on the same technical concept, embodiments of the present invention also provide a charging station, including a charging control system 100 of any of the preceding embodiments or combinations thereof.

[0082] The charging control system provided in this invention adopts a hierarchical control architecture and modular design. The network architecture of the charging control system includes a charging management layer and a power management layer, and optionally, a site monitoring layer. The modular architecture of the charging control system includes a charging control module and a power control module, and optionally, a business control module and an energy storage control module. In this way, the charging control system achieves complete decoupling in terms of function, electrical layout, and physical space, enabling it to be quickly combined and deployed according to application scenarios, saving development time and costs.

[0083] Furthermore, the charging control system provided in this embodiment of the invention employs a combination of single-master control and multi-master automatic coordination among its modules, enabling them to work collaboratively or independently, resulting in high system availability. Moreover, any module failure can automatically disconnect from the control system without affecting the operation of other modules, demonstrating high system robustness and convenient maintenance.

[0084] Therefore, those skilled in the art should recognize that although exemplary embodiments of the present invention have been shown and described in detail herein, many other variations or modifications conforming to the principles of the present invention can be directly determined or derived from the disclosure of the present invention without departing from the spirit and scope of the invention. Thus, the scope of the present invention should be understood and recognized as covering all such other variations or modifications.
