DETAILED DESCRIPTION

[0038] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Generally, the components of the embodiments of the present invention described and shown in the drawings here can be arranged and designed in various different configurations.

[0039] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the invention claimed for protection, but merely represents selected embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0040] It should be noted that similar reference numerals and letters denote similar items in the following drawings, and therefore, once an item is defined in one drawing, further definition and explanation thereof is not required in subsequent drawings.

[0041] In addition, the terms “first”, “second”, etc., if used, are merely used to distinguish between the descriptions and should not be understood as indicating or implying relative importance.

[0042] It should be noted that, in the absence of conflict, the features in the embodiments of the present invention may be combined with each other.

[0043] Please refer to Figure 1 This embodiment provides a charging pile 100 with a power regulation function. The charging pile 100 with a power regulation function includes a charging control unit 1 (Tolly Control Unit, TCU), a charging management unit 2 (Charge Control Unit, CCU), a charging power intelligent control module 3, an AC power distribution module 4, a power conversion module 5, a charging gun 6, a human-computer interaction module 7, etc. Among them, the power conversion module 5 may include a charging module, a DC power distribution module, a metering meter, etc., the human-computer interaction module 7 may include a display screen, a card reader, etc., and the charging control unit 1 is used to connect to the charging management platform 400.

[0044] The charging management unit 2 is used to connect to the charging management platform 400, the human-computer interaction module 7 is connected to the billing control unit 1, and the AC power distribution module 4, the power conversion module 5, and the charging gun 6 are all connected to the charging management unit 2. Among them, the AC power distribution module 4 is used to access the AC power supply 500 of the power grid.

[0045] The charging management unit 2 communicates with the on-board BMS 300 of the charging vehicle through the CAN bus to achieve data interaction and charging power control between the charging pile and the on-board battery.

[0046] During the parameter configuration stage of the charging start process, the charging management unit 2 of the charging pile 100 with power regulation function exchanges information such as the maximum output capacity of the charging pile 100 with power regulation function and the battery charging parameters with the on-board BMS 300 to determine parameters such as voltage and current boundary conditions that both parties can output and accept, and determine whether the charging start requirements are met.

[0047] Specifically, during the parameter configuration phase of the charging startup process, the vehicle-mounted BMS300 sends the PGN1536 power battery charging parameter message (BCP) to the charging management unit 2. Specifically, the vehicle-mounted BMS300 sends the battery charging parameters to the charging management unit 2. If the charging management unit 2 does not receive the message within 5 seconds, it is a timeout error, and the charging management unit 2 immediately ends the charging.

[0048] The charging management unit 2 sends a PGN2048 maximum output capability message (CML) of the charging pile 100 with power regulation function to the vehicle BMS 300. Specifically, the charging management unit 2 sends the maximum output capability of the charging pile 100 with power regulation function to the vehicle BMS 300 to estimate the remaining charging time.

[0049] The vehicle-mounted BMS300 also sends a PGN4096 battery charging requirement message (BCL) to the charging management unit 2. Specifically, during the charging process, the vehicle-mounted BMS300 sends the battery charging requirement to the charging management unit 2 in real time, and the charging management unit 2 adjusts the charging voltage and charging current according to the battery charging requirement to ensure that the charging process proceeds normally. If the charging management unit 2 does not receive the message within 1 second, it is a timeout error, and the charging management unit 2 immediately ends the charging.

[0050] In the constant voltage charging mode, the charging management unit 2 controls the output voltage of the charging pile 100 with power regulation function to meet the voltage requirement of the vehicle battery, and the output current of the charging pile 100 with power regulation function cannot exceed the current requirement of the vehicle battery. When the charging current request in the PGN4096 battery charging requirement message (BCL) is greater than the maximum output current in the PGN2048 maximum output capacity message (CML) of the charging pile 100 with power regulation function, the charging pile 100 with power regulation function outputs at the maximum output capacity; when the charging current request in the BCL message is less than the maximum output current in the CML message, the charging pile 100 with power regulation function outputs at the requested current; when the voltage requirement or current requirement is 0, the charging pile 100 with power regulation function outputs at the minimum output capacity.

[0051] During the charging process, the charging management unit 2 and the onboard BMS 300 send each other their respective charging status, and the data exchange cycle is 50ms. In addition, the onboard BMS 300 sends the specific status information of the power battery and information such as voltage and temperature to the charging management unit 2 as required.

[0052] After receiving the battery charging demand information, the charging management unit 2 determines the actual output voltage and current values ​​according to its own output capacity and the battery charging demand information, and reports the charging status information of the charging pile 100 with power regulation function to the on-board BMS 300 in real time, with a data cycle of 50ms.

[0053] That is to say, the charging management unit 2 sends the charging status message (CCS) of the charging pile 100 with power regulation function of PGN4608 to the on-board BMS300. Specifically, the on-board BMS300 monitors the charging current, voltage value and other information currently output by the charging pile 100 with power regulation function. If the on-board BMS300 does not receive the message within 1s, it is a timeout error, and the on-board BMS300 immediately ends charging.

[0054] At the same time, during the charging process, the onboard BMS300 reports the power battery status information to the charging management unit 2, with a data cycle of 250ms, so that the charging management unit 2 can judge the battery status and decide whether to continue charging. The power battery status information (BSM), single power battery voltage (BMV), power battery temperature (BMT) and other message information are used as the battery detection and analysis data source during the charging process.

[0055] More importantly, at the node between the charging management unit 2 and the on-board BMS 300, the charging power intelligent control module 3 is connected in series, and the charging power intelligent control module 3 is connected to the cloud platform 200. The charging power intelligent control module 3 can control the output of charging messages, control the charging power, provide charging safety warnings, and provide active protection functions.

[0056] After the charging power intelligent control module 3 receives the power control command issued by the cloud platform 200, the charging power intelligent control module 3 performs upper limit control on the charging demand current message sent by the on-board BMS 300, and sends the regulated charging message to the charging management unit 2 of the charging pile 100 with power regulation function, thereby realizing the control of the charging power.

[0057] Please refer to Figure 2 The charging power intelligent control module 3 includes an MCU main control unit 31 and a 4G communication module 32, a local LAN communication module 33, and a power module 34 connected to the MCU main control unit 31. The MCU main control unit 31 is connected to the vehicle-mounted BMS 300 and the charging management unit 2 through the CAN bus. The power module 34 integrates an AC / DC power supply with a maximum power of less than 5W. In this way, the charging power intelligent control module 3 is compatible with 4G and local LAN communication modes, can achieve seamless switching between 4G wireless and local Internet, and supports remote software upgrades.

[0058] Please refer to Figure 3 The charging power intelligent control module 3 monitors, controls, calculates edge high-risk algorithms, and uploads data to the local station controller 600 or the cloud platform 200 through the charging process of new energy vehicles, so that the cloud platform 200 can evaluate and calculate the charging operation power demand and the operating status of the power battery system, and finally form a power control instruction or a diagnostic report for the tested new energy vehicle. The charging power intelligent control module 3 has local communication LAN communication capability and 4G network function, and can upload data to the local station controller 600 or the cloud platform 200 to interact with the algorithm. The charging power intelligent control module 3 is suitable for internal installation or modification of national standard DC charging piles, and is suitable for various power charging piles using GB / T27930-2015 (compatible with 2011).

[0059] The charging power intelligent control module 3 can mainly realize the following functions:

[0060] (1) Data transparent transmission function

[0061] The charging power intelligent control module 3 realizes the collection and transmission of message information between the on-board BMS300 and the charging management unit 2 in the entire charging process, and acts as a transparent link when power control or active prevention and control is not required. After receiving the message information from the charging management unit 2 and the on-board BMS300, it transparently transmits it to the other party without making any changes to the message, while ensuring the timeliness requirements of message transmission, that is, meeting the national standard GB / T 27930-2015.

[0062] (2) Data collection and reporting function

[0063] While completing data transparent transmission, the charging power intelligent control module 3 collects the output power information of the charging pile 100 with power regulation function, the demand information of the on-board BMS300, the battery information, etc. during the charging process according to the business and function needs (battery detection, power control, etc.), and uploads it to the local station controller 600 or the cloud platform 200 to support the development of businesses such as grid interaction and battery detection.

[0064] (3) Charging power adjustment function

[0065] During the charging process, when the charging power intelligent control module 3 receives a power control instruction issued by the local station controller 600 or the cloud platform 200, it modifies the voltage and current demand data of the on-board BMS300 according to the power control instruction and in combination with the operating status and charging data of the charging pile 100 with power regulation function and the on-board BMS300 to achieve the goal of power regulation and ensure the normal progress of the charging process and the system safety and stability of the charging pile 100 with power regulation function and the on-board BMS300.

[0066] (4) Active prevention and control function

[0067] During the charging process, the real-time data of the CAN bus will be uploaded to the cloud platform 200 through the charging power intelligent control module 3, and the cloud service of the cloud platform 200 will provide algorithm detection and conduct safety warning. When an abnormal situation occurs, the cloud service will issue an alarm instruction, which will be executed by the charging power intelligent control module 3, thereby terminating the entire charging process and realizing active safety protection.

[0068] Among them, please refer to Figure 4 The process of the charging power intelligent control module 3 performing the charging power adjustment function is as follows:

[0069] S1: After the charging pile 100 with power regulation function is powered on, the charging power intelligent regulation module 3 is automatically started.

[0070] S2: The charging power intelligent control module 3 actively connects with the cloud platform 200. After the connection, the module online authentication, status update and other operations are completed.

[0071] S3: The charging power intelligent control module 3 maintains the connection status with the cloud platform 200, waits for the command of the cloud platform 200, sends the heartbeat information and the time information as required, and reports the status data after receiving the active call information from the cloud platform 200. In this way, the charging power intelligent control module 3 has the function of automatic time synchronization and calibration, and the daily time error does not exceed 1 second, ensuring that the data collection and information reporting time are synchronized with the cloud platform 200 or the local station controller 600.

[0072] S4: The charging power intelligent control module 3 receives the power control instruction issued by the cloud platform 200, and includes it in the module execution task, and regularly checks the effectiveness of the task. When there is no car charging during the validity period of the task, the charging power adjustment is not performed. When there is a car charging, the charging power is adjusted according to the requirements of the power control instruction.

[0073] S5: When the electric vehicle is plugged in to start charging, the charging power intelligent control module 3 collects and detects the interaction information between the on-board BMS 300 and the charging management unit 2.

[0074] Specifically, the on-board BMS300 and the charging pile exchange information with the charging management unit 2 through the CAN bus on the charging gun 6 according to the data content specified in the national standard GB / T 27930-2015. The interactive information includes the power battery charging parameter message (BCP), the maximum output capacity message (CML) of the charging pile 100 with power regulation function, the battery charging demand message (BCL), the charging status message (CCS) of the charging pile 100 with power regulation function, the power battery status information message (BSM), etc. The charging power intelligent control module 3 will collect and detect these interactive information to facilitate the execution of the charging power regulation function and the active prevention and control function.

[0075] S6: The charging power intelligent control module 3 performs the charging power adjustment function according to the power adjustment instruction and the interaction information.

[0076] When a car is charging and the charging power intelligent control module 3 receives a power control instruction and needs to adjust the charging power, the charging power intelligent control module 3 comprehensively judges the power control instruction, the output capacity of the charging pile, the charging demand of the on-board BMS300 and other information, and adjusts the charging power under the premise of meeting the charging specification requirements and safety, and modifies the current demand value in the battery charging demand message (BCL) to adjust the output power of the charging pile 100 with power regulation function, and respond to the cloud platform 200 instruction. Among them, according to the battery charging demand message (BCL) interaction time requirement (50ms), the charging power intelligent control module 3 can realize millisecond-level modification and power regulation of the battery charging demand message (BCL) to meet the power grid frequency response requirements.

[0077] Of course, it is understandable that when the charging power intelligent control module 3 does not receive the power control command or does not collect and detect the interactive information related to the function, the charging power intelligent control module 3 transparently transmits the interactive information between the on-board BMS 300 and the charging management unit 2 of the charging pile 100 with power regulation function to realize the data transparent transmission function. Moreover, the charging power intelligent control module 3 automatically maintains the heartbeat message when there is no charging, and maintains communication and connection with the cloud platform 200 or the local station controller 600.

[0078] S7: During the charging process, the charging power intelligent control module 3 automatically reports the charging information regularly according to the communication specification, and responds to the call command of the cloud platform 200 in real time. After charging is completed, it automatically stops reporting and returns to execute S3.

[0079] S8: When the validity period of the power control instruction expires, the power control is terminated, the charging power of the charging pile 100 with power regulation function is restored to be controlled by the on-board BMS 300, and the charging power intelligent control module 3 returns to execute S5.

[0080] Among them, please refer to Figure 5 The process of the charging power intelligent control module 3 executing the active prevention and control function includes the above S1 to S5, and also includes the following steps:

[0081] S9: During the charging process, the charging power intelligent control module 3 collects the power battery status information message (BSM) and reports it to the cloud platform 200 regularly according to the communication specification.

[0082] S10: The cloud platform 200 detects and analyzes the operation and safety status of the vehicle power battery through the battery detection algorithm program according to the power battery status information message reported by the charging power intelligent control module 3, and the cloud platform 200 saves and records the analysis results.

[0083] S11: For charging processes with abnormal analysis results monitored by the cloud platform 200, the cloud platform 200 returns abnormal information based on the analysis conclusion to remind the car owner, and the charging power intelligent control module 3 generates abnormal message information to end the charging process, thereby realizing the active prevention and control function of the charging process. According to the battery data analysis results, the charging process can be interrupted, paused, and other operations performed within the shortest data interaction cycle (50ms) between the charging pile 100 with power regulation function and the vehicle-mounted BMS300, realizing millisecond-level protection actions.

[0084] Of course, it is understandable that if the analysis result of the cloud platform 200 is normal, the charging power intelligent control module 3 does not perform any operation.

[0085] The beneficial effects of the charging pile 100 with power regulation function provided in this embodiment include:

[0086] 1.
