Description

Technical Field

[0001] The present invention relates to the technical field of charger control, and in particular to a charger orderly charging control system and method capable of expanding multiple devices. Background Art

[0002] In the current market, with the popularity of electric vehicles, the construction of charging stations in old communities and the expansion of old charging stations are growing. However, the capacity of the front-stage transformers of these charging stations is often limited, which makes it difficult to meet the needs of charging a large number of electric vehicles at the same time. In order to ensure that the charging process does not exceed the carrying capacity of the front-stage transformer and prevent equipment damage or grid fluctuations caused by overload, it is necessary to use an orderly charging controller to manage the charging behavior of the chargers in the charging station.

[0003] The orderly charging controller uses intelligent algorithms to dynamically adjust the charging power and charging time of each charger according to the real-time load of the transformer and the charging needs of the charger, thereby achieving a balanced distribution of the charging load and ensuring the safety and efficiency of the entire charging process. However, the orderly charging controllers currently on the market are limited by their size and standardized product design for a wide range of market needs, and the number of chargers that a single controller can directly connect and control is relatively limited.

[0004] In the case of large-scale charging stations or scenarios where a large number of charging devices need to be controlled, a single orderly charging controller obviously cannot meet the needs. Therefore, an innovative solution is urgently needed to expand the number of connected devices of the orderly charging controller to meet the needs of larger-scale charging station management. Summary of the invention

[0005] In order to overcome the defects of the above-mentioned prior art, the purpose of the present invention is to provide a charger orderly charging control system that can be expanded to multiple devices, so as to solve the technical problem that the prior art cannot meet the charging needs of a large number of charger devices.

[0006] The present invention is achieved through the following technical solutions: In a first aspect, the present invention provides a charger orderly charging control system that can expand multiple devices, including a power distribution meter, a management platform, an orderly charging controller, an AC source, and a plurality of slave controllers; The power distribution meter and the management platform are connected to the control end of the orderly charging controller; the driving end of the orderly charging controller is respectively connected to the input ends of several slave controllers, wherein the output end of each slave controller is correspondingly connected to several charging piles; The output end of the AC source is respectively connected to the orderly charging controller and the power supply end of a plurality of slave controllers.

[0007] Preferably, the orderly charging controller includes a main control board, a first power supply and a first switch; The power distribution meter and the management platform are connected to the control end of the main control board; The output end of the AC source is connected to the power end of the main control board after power conversion by the first power supply; The driving end of the main control board is connected to the input end of the first switch; The output end of the first switch is connected to a plurality of slave controllers.

[0008] Furthermore, the output end of the main control board is also connected to a display screen for displaying control data.

[0009] Furthermore, a control module is provided in the main control board, and the input end of the control module is connected to the signal input module and the power supply module; the input end of the signal input module is connected to the output end of the power distribution meter and the management platform, and the input end of the power supply module is connected to the output end of the AC source via the first power supply; the output end of the control module is connected to the signal output module; and the signal output module is respectively connected to the first switch and the display screen.

[0010] Furthermore, the output end of the first switch is connected to a plurality of slave controllers via Ethernet LAN or CAN communication.

[0011] Furthermore, the number of the Ethernet LAN interfaces or CAN communication interfaces of the first switch corresponds to the number of the slave controllers.

[0012] Preferably, the slave controller includes a second power supply and a plurality of second switches; The output end of the AC source is connected to the input end of the second power supply; The output end of the second power supply and the driving end of the orderly charging controller are respectively connected to the input ends of a plurality of second switches; wherein the output end of each second switch is respectively connected to a plurality of charging piles.

[0013] Furthermore, the driving end of the orderly charging controller is respectively connected to a plurality of second switches via Ethernet LAN or CAN communication.

[0014] Furthermore, the output end of the second switch is respectively connected to the plurality of charging piles via Ethernet LAN or CAN communication, and the number of the Ethernet LAN interface or CAN communication interface of the second switch corresponds to the number of the plurality of charging piles.

[0015] In a second aspect, the present invention further provides a method for controlling orderly charging of a charger capable of scalability to multiple devices, based on the above-mentioned method for controlling orderly charging of a charger capable of scalability to multiple devices, characterized in that it comprises the following steps: When the system starts, the AC source supplies power to the ordered charging controller and each slave controller respectively. The distribution meter monitors the power status of the power grid in real time and sends relevant information to the ordered charging controller. The ordered charging controller receives control instructions from the management platform, and processes the instructions according to preset algorithms and logics. The processed instructions are then used to control several charging piles through several slave controllers. The charging piles charge the electric vehicles according to the received control instructions.

[0016] Compared with the prior art, the present invention has the following beneficial technical effects: The present invention provides a charger orderly charging control system that can expand multiple devices. By connecting the power distribution meter with the management platform, the power consumption during the charging process can be monitored and controlled in real time to achieve precise energy management. The management platform can summarize and analyze data, optimize the charging strategy, and improve the charging efficiency. By connecting a number of slave controllers through the driving end of the orderly charging controller, each slave controller can be connected to multiple charging piles, so that the entire system can be easily expanded to adapt to charging scenarios of different scales and requirements, improving the flexibility and adaptability of the system, and being able to meet the charging needs of a large number of chargers.

[0017] Furthermore, the main control board, as the core of the orderly charging controller, centrally receives control instructions from the power distribution meter and the management platform, and accurately controls the charging process according to these instructions. This centralized control method simplifies the system structure and improves management efficiency. The first power supply provides a stable and reliable power supply to the main control board, ensuring that the orderly charging controller can work continuously and stably. The first switch, as the hub of data transmission, efficiently transmits the control instructions of the main control board to each slave controller. At the same time, since the switch has multiple output ports, it can easily connect multiple slave controllers to achieve control of more charging piles. This design improves the scalability and flexibility of the system.

[0018] Furthermore, a control module is provided in the main control board, and the input end of the control module is connected to the signal input module and the power module; the input end of the signal input module is connected to the output end of the power distribution meter and the management platform, and the input end of the power module is connected to the AC source; the output end of the control module is connected to the signal output module; and the signal output module is respectively connected to the first switch and the display screen.

[0019] Furthermore, the main control board integrates the control module, signal input module, power module, signal output module, etc. to form a highly modular design. The signal input module is responsible for receiving control signals from the power distribution meter and management platform and passing them to the control module. The control module performs logical processing and decision-making based on these signals, and then sends the control instructions to the first switch and the display screen through the signal output module. This efficient signal processing process ensures rapid response and precise control of the charging process. The power module obtains power from the AC source and provides a stable and reliable power supply to the main control board and its various modules. The signal output module is connected to the display screen, which can display key information of the charging process in real time, such as charging status, charging speed, remaining time, etc.

[0020] Furthermore, both Ethernet LAN and CAN communications support multi-device connections, so the scale of the charging system can be easily expanded by adding slave controllers. This allows the system to be flexibly adjusted according to actual needs to meet the needs of charging stations of different sizes.

[0021] Furthermore, each slave controller is equipped with an independent second power supply. Even if a power supply fails, it will not affect the operation of the entire charging system, which enhances the reliability and stability of the system and ensures the continuity of the charging process. By connecting multiple charging piles to the second switch, the distributed transmission of control signals is realized, reducing the risk of single point failure, because even if a switch or charging pile has a problem, it will not affect the normal operation of other parts. The slave controller adopts a modular design, which can easily increase or decrease the number of second switches and charging piles to adapt to charging stations of different sizes and needs. This design makes the system have good scalability and flexibility.

[0022] The present invention also provides a method for controlling the orderly charging of a charger that can be expanded to multiple devices. The present invention realizes efficient and orderly management of charging piles by receiving and processing control instructions from a management platform through an orderly charging controller. This centralized control method can ensure that the charging process is carried out according to the preset algorithm and logic, avoid disorderly competition between charging piles, and improve charging efficiency and the stability of the power grid. The distribution meter monitors the power status of the power grid in real time and sends relevant information to the orderly charging controller. This enables the system to dynamically adjust the charging plan to adapt to changes in the power grid load, thereby avoiding adverse situations such as overload or underload. This real-time monitoring and dynamic adjustment capability helps to protect power grid equipment and extend its service life. Through orderly charging control, the present invention can optimize the utilization of power resources. During the peak period of power grid load, the system can limit the power of some charging piles or delay the charging time to reduce the burden on the power grid. During the low period of power grid load, the remaining power can be fully utilized for charging to improve the utilization rate of power resources. BRIEF DESCRIPTION OF THE DRAWINGS
