[0051] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0052] When faced with the demand for higher charging power and faster charging speed from electric vehicles, current charging stations can concentrate the power of multiple charging stations onto a single charging gun through a combiner charging device without upgrading the internal power unit, thus achieving the goal of increasing charging power and speeding up charging. However, current combiner charging devices cannot centrally and precisely control the output power of multiple charging stations.

[0053] In view of this, the charging control method of this application embodiment determines the allocated power of each charging pile by splitting the power demand of the electrical equipment, and determines the target power of each charging pile based on the maximum power currently available for each charging pile and the corresponding allocated power, so as to realize the dynamic scheduling of multiple charging piles, make full use of charging resources, improve charging efficiency, and thus better meet the dynamic charging needs of electrical equipment.

[0054] The charging control method, charging device, equipment, and storage medium of this application will be described in detail below with reference to the accompanying drawings. Unless otherwise specified, the features of the following embodiments and implementations can be combined with each other.

[0055] Figure 1 This is a schematic diagram of the structure of a current charging device according to an embodiment of this application; Figure 2 This is a schematic diagram of the internal structure of a current charging device according to an embodiment of this application.

[0056] refer to Figure 1 andFigure 2 The combined charging device of this application embodiment includes multiple connection sockets 1, a vehicle plug 2, and a control module 3. The multiple connection sockets 1 are used to connect the charging guns of multiple charging piles 5 respectively. The vehicle plug 2 is used to connect the electrical device 6. The control module 3 is connected to the multiple connection sockets 1 and the vehicle plug 2, and is communicatively connected to the multiple charging piles 5 and the electrical device 6 respectively. The control module 3 is configured to acquire the power demand of the electrical device 6, split the power demand of the electrical device 6, determine the allocated power of each charging pile 5, acquire the maximum power currently available from each charging pile 5, and, based on the allocated power and maximum power of each charging pile 5, determine the target power of each charging pile 5, and, based on the target power of each charging pile 5, control each charging pile 5 to charge the electrical device 6.

[0057] For example, the electrical device 6 can be an electric vehicle. The electric vehicle is communicatively connected to the control module 3 via the vehicle plug 2. The charging gun of the charging pile 5 is communicatively connected to the control module 3 via the connection socket 1. The number of connection sockets 1 is set according to the number of charging piles 5, and this application does not limit this.

[0058] In some embodiments, the electrical device 6 is an electric vehicle. A combiner charging device is used to centrally control and supply power from multiple charging piles 5 to the electric vehicle. The control module 3 communicates with both the electric vehicle's BMS (Battery Management System) and the multiple charging piles 5. A communication line 4 is provided between the control module 3 and the vehicle socket, and the communication line 4 is connected to the terminal of the vehicle socket to enable communication interaction between the control module 3 and the electric vehicle's BMS. A communication line 4 is provided between each connection socket 1 and the control module 3. The communication line 4 includes at least positive and negative power lines, an insulation detection line, and a ground wire. The communication line 4 is connected to the terminal of the connection socket 1 to enable communication interaction between the control module 3 and the multiple charging piles 5.

[0059] In some embodiments, the communication line 4 between each connection socket 1 and the control module 3 has a unique identification ID. This configuration allows the control module 3 to communicate one-to-one with each charging pile 5 connected to each connection socket 1. Specifically, the control module 3 uses a single-wire standard communication protocol with the electric vehicle's BMS, including accepting dynamic power demand requests, insulation detection requests, and power-off unlocking requests from the electric vehicle.

[0060] In some embodiments, the control module 3 uses a multi-line standard communication protocol with multiple charging piles 5. That is, the control module 3 communicates with each connected charging pile 5 using the standard communication protocol to split the power demand of the electric vehicle, distribute the allocated power of each charging pile 5 to each charging pile 5, and receive the maximum power that each charging pile 5 can provide.

[0061] In some embodiments, the control module 3 collects the maximum power that each charging pile 5 can currently provide, performs centralized analysis, and sends the analysis results to the BMS of the electric vehicle via a message. At the same time, based on the power demand of the electric vehicle, it determines the target power of each charging pile 5, distributes the target power of each charging pile 5 to each charging pile 5, and merges the target power output of each charging pile 5 and sends it to the electric vehicle.

[0062] Through communication and interaction with the electric vehicle's BMS and charging piles 5, the control module 3 can accurately acquire the dynamic power demand of the electric vehicle and allocate it to each charging pile 5, achieving precise control of the charging process. This ensures that each charging pile 5 meets the charging needs of the electric vehicle, reducing the computational burden on the electric vehicle's BMS. Centralized control and allocation of charging power by the control module 3 simplifies the design of the electric vehicle's BMS, reduces the complexity of the BMS system, and improves charging efficiency. Furthermore, by establishing communication connections with multiple charging piles 5, the control module 3 can monitor the status and output power of each charging pile 5 in real time, promptly detect potential faults or anomalies, and take timely measures to ensure the safety and reliability of the charging process.

[0063] Figure 3 This is a flowchart of a charging control method according to an embodiment of this application. (Reference) Figure 3 This application provides a charging control method applied to a combiner charging device, the method comprising the following steps:

[0064] Step 100: Obtain the power requirement of the electrical equipment.

[0065] In some embodiments, step 100 can be implemented in the following manner:

[0066] The electric vehicle's BMS sends a charging request to the control module, which includes the BMS's power demand. The control module receives the power demand from the electrical equipment.

[0067] For example, a charging request can be in the form of a charging request message.

[0068] Step 200: Break down the power demand of the electrical equipment and determine the allocated power for each charging station;

[0069] Specifically, the control module can break down the required power to generate the allocated power for each charging station. For example, the required power can be evenly distributed according to the number of charging stations.

[0070] For example, when the power demand of the BMS of an electric vehicle is 100kW, and there are two charging piles, the power demand can be divided into two 50kW units and distributed to each charging pile respectively.

[0071] Step 300: Obtain the maximum power that each charging station can currently provide.

[0072] Figure 4 This is a schematic diagram of a current charging device according to an embodiment of this application. (Reference) Figure 4 In some embodiments, the control module sends the allocated power of each charging pile to the corresponding charging pile in the form of a charging demand request. After receiving the charging demand request from the control module, each charging pile sends a charging capacity message to the control module, which includes the maximum power that each charging pile can currently provide.

[0073] Step 400: Determine the target power for each charging station based on its allocated power and maximum power.

[0074] In some embodiments, after receiving the charging capacity message from each charging pile, the control module analyzes it and sends the analysis results to the BMS of the electric vehicle as a charging capacity result message. Simultaneously, the control module determines the target power for each charging pile based on its allocated power and maximum power.

[0075] In some embodiments, step 400 is performed by the following steps:

[0076] Step 401: Compare the allocated power of each charging station with its maximum power.

[0077] Step 402: If the maximum power of each charging pile is greater than or equal to the corresponding allocated power, then the allocated power of each charging pile is determined as the target power for each charging pile.

[0078] In some embodiments, the control module compares the allocated power of each charging pile with the maximum power. If the maximum power of each charging pile exceeds the corresponding allocated power determined by the control module, the target power of each charging pile can be determined as the allocated power of each charging pile.

[0079] For example, when the power demand of the BMS of an electric vehicle is 100kW and there are two charging piles, the power demand can be split into two 50kW units and distributed to each charging pile respectively. When the maximum power of each charging pile is 60kW, the target power of each charging pile is determined to be 50kW.

[0080] This configuration simplifies the logic and calculation process of the control module, thereby effectively improving operating efficiency and charging efficiency.

[0081] In some embodiments, the method further includes:

[0082] Step 403: If the maximum power of each charging pile is greater than or equal to the corresponding allocated power, and the maximum power of the first charging pile exceeds a preset value, then a prompt message is output to the user device. This prompt message is used to remind the user to disconnect other charging piles from the combined charging device.

[0083] In some embodiments, when the maximum power of a first charging pile among multiple charging piles connected to the combiner charging device exceeds a preset value, a prompt message can be sent to the BMS of the electric vehicle through the control module. The prompt message includes a charging capacity result message and is used to prompt the user to unplug the remaining charging piles connected to the combiner charging device.

[0084] Understandably, the first charging station can be any one or more of the multiple charging stations connected to the combiner charging device, specifically determined by the charging capacity of each charging station. After disconnecting from other charging stations, the combiner charging device remains connected to the first charging station.

[0085] In one embodiment, the preset value can be the required power value or a set power value that allows charging.

[0086] In one embodiment, the charging capabilities of multiple charging piles connected to the charging hub can be obtained, and the charging pile with a charging capability exceeding a preset value can be identified as the first charging pile.

[0087] For example, when the power demand of the electric vehicle's BMS is 100kW, the preset value can be set to 80kW. That is, when the maximum power of a first charging pile exceeds 80kW, the control module will send a charging capacity result message to the electric vehicle's BMS and remind the user to unplug other charging piles connected to the combiner charging device. In other words, the first charging pile can meet the charging needs of the electric vehicle, and other charging piles can be unplugged so that they can charge other loads.

[0088] Of course, there can be multiple first charging piles. If the maximum power of multiple first charging piles exceeds the preset value, the system can determine which charging pile to keep connected to the charging device based on the usage of the charging pile (such as the last usage time and historical usage duration), and output a prompt message to remind the other first charging piles and other charging piles to be disconnected.

[0089] This setup ensures that the remaining charging stations connected to the charging hub can meet the charging needs of electric vehicles, while reserving excess charging stations for other users. This maximizes the use of charging station resources, meets the charging needs of more users, reduces waiting time, and improves the efficiency of charging facilities.

[0090] In some embodiments, the method further includes:

[0091] Step 404: If the maximum power of each charging pile is less than the corresponding allocated power, then the maximum power of each charging pile is determined as the target power for each charging pile.

[0092] In some embodiments, after comparing the allocated power and maximum power of each charging pile in step 401, if the maximum power of each charging pile is less than the corresponding allocated power decomposed by the control module, it can be determined that the sum of the maximum power of the multiple charging piles cannot meet the power requirements of the electric vehicle. For example, when the BMS of the electric vehicle requires 100kW of power, and there are two charging piles, the required power can be divided into two 50kW units and distributed to each charging pile respectively. When the maximum power of each charging pile is 40kW, the target power of each charging pile is determined to be 40kW.

[0093] After sending a charging capacity result message to the BMS of the electric vehicle, the control module determines the target power of each charging pile and the maximum power that each charging pile can currently provide, ensuring that each charging pile can provide its maximum power to maximize charging. Thus, when the maximum power of each charging pile increases, the control module can dynamically adjust the target power output of each charging pile to ensure that the maximum power of the charging pile is fully utilized, thereby effectively improving charging efficiency.

[0094] In some embodiments, the method further includes:

[0095] Step 405: If there are multiple charging piles with a maximum power greater than or equal to the corresponding allocated power, and charging piles with a maximum power less than the corresponding allocated power, then adjust the allocated power of each charging pile based on the sum of the maximum power of the multiple charging piles and the required power.

[0096] In some embodiments, after step 401 compares the allocated power and maximum power of each charging pile, if there are some charging piles whose maximum power is greater than or equal to the corresponding allocated power and some charging piles whose maximum power is less than the corresponding allocated power, then the allocated power of each charging pile is flexibly adjusted based on the sum of the maximum power of multiple charging piles and the required power.

[0097] The above scheme achieves a reasonable power distribution among multiple charging piles by flexibly adjusting the power allocation of each charging pile. This avoids insufficient charging power due to the maximum power limitation of some charging piles, thereby optimizing resource utilization, balancing the charging load among various charging piles, and improving the overall efficiency of the charging system.

[0098] In some embodiments, step 405 is specifically performed in the following manner:

[0099] Based on the proportion of each charging pile's maximum power to the sum of the maximum power of all charging piles, the demand power is re-allocated to determine the new power allocation for each charging pile. The higher the maximum power of a charging pile, the greater the new target power allocation.

[0100] For example, when the power demand of the electric vehicle's BMS is 120kW, and there are two charging stations, the power demand can be split into two 60kW units and distributed to each charging station respectively. When the maximum power of the two charging stations is 50kW and 80kW respectively, the following steps are taken to determine the new power allocation for each charging station:

[0101] Step 1: Add the maximum power of the two charging piles together, i.e., 50kW + 80kW = 130kW, to get the sum of the maximum power of the multiple charging piles.

[0102] Step 2: Calculate the proportion of the maximum power of each charging pile to the sum of the maximum power of the two charging piles. That is, divide the maximum power of each charging pile by the sum of the maximum power of the multiple charging piles, i.e., 50kW / 130kW≈0.3846 and 80kW / 130kW≈0.6154, to obtain the proportion factor of the two charging piles.

[0103] Step 3: Allocate the required power proportionally to each charging station. Multiply the required power by the scaling factor for the first charging station, i.e., 120kW * 0.3846 ≈ 46.15kW, to obtain the target power for the first charging station. Multiply the required power by the scaling factor for the second charging station, i.e., 120kW * 0.6154 ≈ 73.85kW, to obtain the target power for the second charging station. The target powers for the two charging stations are determined to be 46.15kW and 73.85kW, respectively.

[0104] In some embodiments, the method further includes:

[0105] Step 406: If at least some of the charging piles have a maximum power less than a preset threshold, the user is prompted to disconnect the charging piles with a maximum power less than the preset threshold from the charging device.

[0106] In some embodiments, when at least one of the multiple charging piles connected to the combiner charging device has a maximum power lower than a preset threshold, the control module can send a charging capability result message to the BMS of the electric vehicle and issue a prompt to the user, prompting the user to unplug the charging pile with a maximum power lower than the preset threshold.

[0107] For example, when the power demand of the BMS of an electric vehicle is 100kW, the preset threshold can be set to 30kW. That is, when there are multiple charging piles connected to the combiner charging device, at least one of the charging piles has a maximum power of less than 30kW, the control module will send a charging capacity result message to the electric vehicle BMS and remind the user to change the charging pile. That is, the user can disconnect the charging pile with a maximum power of less than the preset threshold from the combiner charging device and try to connect other charging piles to the combiner charging device, and repeat steps 100 to 400.

[0108] The above scheme allows for the full utilization of the maximum power of each charging station by redetermining the power allocation. This ensures efficient charging while balancing the load between charging stations, preventing any single charging station from being overloaded or wasting power resources.

[0109] Step 500: Based on the target power of each charging pile, control each charging pile to charge the electrical equipment.

[0110] In some embodiments, the control module sends the determined target power for each charging pile to the corresponding charging pile. Each charging pile, upon receiving the corresponding target power from the control module, outputs the corresponding target power back to the control module. The control module then merges the target power outputs from each charging pile and outputs the merged target power to the electric vehicle's BMS for charging the electric vehicle.

[0111] The above solution breaks down and analyzes the needs of electrical equipment, and determines the target power of each charging pile based on its allocated power and maximum power. This enables dynamic scheduling of multiple charging piles, effectively solving the problem that the combined charging device cannot meet the dynamic needs of electrical equipment. It makes full use of charging resources, improves charging efficiency, and ensures the safety and reliability of the charging control method.

[0112] In some other embodiments, steps 200 and 300 can be interchanged; that is, step 300 can be executed first, followed by step 200. The interchanged charging method then includes the following steps:

[0113] Step 100: Obtain the power requirement of the electrical equipment.

[0114] Step 300: Obtain the maximum power that each charging station can currently provide.

[0115] In some embodiments, the control module sends a charging demand request to each charging pile. After receiving the charging demand request from the control module, each charging pile sends a charging capability message to the control module, which includes the maximum power that each charging pile can currently provide.

[0116] Step 200: Break down the power demand of the electrical equipment and determine the allocated power for each charging station.

[0117] In some embodiments, the control module breaks down the required power based on the maximum power and required power of each charging station to generate the allocated power for each charging station.

[0118] By using the above method, the maximum power of each charging pile is first obtained, and then the required power is divided based on the maximum power, thereby more accurately dividing the required power, ensuring that the charging capacity of each charging pile is fully utilized, simplifying the steps of the charging control method, and improving charging efficiency.

[0119] Step 400: Determine the target power for each charging station based on its allocated power and maximum power.

[0120] In some embodiments, after receiving the charging capacity message from each charging pile, the control module analyzes it and sends the charging capacity analysis result to the BMS of the electric vehicle as a charging capacity result message. Simultaneously, in this embodiment, the allocated power for each charging pile is determined as the target power for each charging pile.

[0121] Step 500: Based on the target power of each charging pile, control each charging pile to charge the electrical equipment.

[0122] In some embodiments, the control module sends the determined target power for each charging pile to the corresponding charging pile. Each charging pile, upon receiving the corresponding target power from the control module, outputs the corresponding target power back to the control module. The control module then merges the target power outputs from each charging pile and outputs the merged target power to the electric vehicle's BMS for charging the electric vehicle.

[0123] The above scheme enables dynamic scheduling of multiple charging piles. By first obtaining the maximum power of each charging pile and then allocating the required power based on the maximum power, the required power can be allocated more accurately, ensuring that the charging capacity of each charging pile is fully utilized. This simplifies the steps of the charging control method, improves charging efficiency, and ensures the safety and reliability of the charging control method.

[0124] Figure 5 This is a schematic diagram of a communication interaction process according to another embodiment of this application. Figure 7This is a flowchart of an insulation test according to an embodiment of this application; see reference. Figure 5 and Figure 7 In some embodiments, before performing step 100, the charging control method of this application may further include the following steps:

[0125] Step 10: Obtain the insulation test request sent by the electrical equipment and send the insulation test request to each charging pile.

[0126] In some embodiments, before charging begins, the BMS of the electric vehicle, which is connected to the control module, sends an insulation detection request to the control module. After receiving the insulation detection request from the BMS of the electric vehicle, the control module sends an insulation detection request to each charging station.

[0127] Step 20: Obtain the insulation test results for each charging station.

[0128] In some embodiments, each charging pile performs relevant testing upon receiving an insulation testing request and sends the insulation testing results to the control module. The insulation testing results are used to determine the insulation status of each charging pile, i.e., whether it meets safety requirements.

[0129] Step 30: Based on the insulation test results of each charging pile, determine the charging piles that have passed the insulation test.

[0130] Specifically, the control module analyzes the insulation test results of each charging pile after obtaining them and determines which charging piles pass the insulation test based on the analysis results. Charging piles that pass the insulation test can be used for subsequent charging.

[0131] In some embodiments, after step 30, the charging control method of this application further includes:

[0132] Step 1: If the insulation test of multiple charging piles passes, a test pass message is sent to the electrical equipment. The test pass message is used to indicate that there is a charging pile available for the electrical equipment.

[0133] Specifically, once it is determined that multiple charging piles have passed the insulation test, all of them can be used for subsequent charging, and the control module can send a test pass message to the BMS of the electric vehicle.

[0134] Step 2: If there are charging piles among the multiple charging piles that have failed the insulation test, then the charging piles that have failed the insulation test will be blocked, and a test pass message will be sent to the electrical equipment.

[0135] Specifically, if any charging pile fails the insulation test among multiple charging piles, the control module will continue to attempt to send insulation test requests to the charging piles that failed the insulation test within a set time. If a message indicating that the insulation test passed is received within the set time, step one above will continue. If no message indicating that the insulation test passed is received within the set time, the charging pile that failed the insulation test will be blocked. The control module can send a request to the BMS of the electric vehicle for the charging gun of the charging pile that failed the insulation test, or a request to replace the charging gun. The remaining charging piles that passed the insulation test can be used for subsequent charging, and the control module can send a message indicating that the test passed to the BMS of the electric vehicle.

[0136] By continuously sending insulation test requests to multiple charging stations and waiting for the insulation test success message, the success rate of the charging equipment can be increased. Even if the insulation test fails, there is still a chance to receive a normal test success message from the charging station within a set time, thereby improving charging availability.

[0137] Step 3: If the insulation test of multiple charging piles fails, a test failure message is sent to the electrical equipment. The test failure message is used to indicate that there is no charging pile available for the electrical equipment.

[0138] Specifically, if insulation detection fails at multiple charging stations, the control module will continue to attempt to send insulation detection requests to the charging stations within a set time. If an insulation detection pass message is received within the set time, step one above will continue. If no insulation detection pass message is received within the set time, a detection failure message will be sent to the electric vehicle's BMS.

[0139] By employing the above approach, the success rate of the charging equipment's detection can be increased by continuously sending insulation test requests to multiple charging stations before charging and waiting for the insulation test success message. Even if an insulation test fails, there is still a chance to receive a normal detection success message from the charging station within a set time, thereby improving charging availability. By sending a detection failure message to the electric vehicle's BMS, users can be promptly notified of insulation test failures at charging stations, providing accurate status information so that users can take timely measures to select other available charging stations, thus improving the user experience.

[0140] In some embodiments, Figure 6 This is a schematic diagram of a communication interaction process according to another embodiment of this application. Figure 8 This is a flowchart illustrating a power-off unlocking method according to an embodiment of this application; see reference. Figure 6 and Figure 8 After performing step 500, the charging control method of this application embodiment further includes:

[0141] Step 600: Obtain the power outage unlock request sent by the power-consuming device and send the power outage unlock request to each charging pile.

[0142] Specifically, after charging is complete, the electric vehicle's BMS sends a power-off unlock request to the control module. After receiving the power-off unlock request from the electric vehicle's BMS, the control module sends the power-off unlock request to each charging station.

[0143] Step 700: Obtain the power outage unlocking result for each charging station.

[0144] In some embodiments, after receiving a power-off unlocking request from the control module, each charging pile performs a corresponding power-off unlocking operation and sends the power-off unlocking result to the control module.

[0145] Step 800: Based on the power outage unlocking result of each charging station, complete the charging of the electrical equipment.

[0146] Specifically, after obtaining the power-off unlocking result from each charging pile, the control module sends a power-off unlocking result message to the BMS of the electric vehicle and completes the charging of the electric vehicle.

[0147] In some embodiments, step 800 is implemented through the following steps:

[0148] Step 1: If the power-off unlocking result of each charging pile indicates that the power-off unlocking was successful, a power-off unlocking success message is sent to the device and a request is made to disconnect from the device in order to complete the charging of the device. The power-off unlocking success message is used to indicate that the device has successfully unlocked the power of each charging pile.

[0149] In some embodiments, if multiple charging piles are successfully de-energized and unlocked, the control module sends a power-off unlock success message to the BMS of the electric vehicle and requests to disconnect the connection between the combiner charging device and the electric vehicle, i.e., requests to remove the charging gun.

[0150] Step 2: If there is a charging pile that indicates a power-off unlocking failure, a power-off unlocking failure message is sent to the device, and the charging pile that failed to unlock is forcibly powered off to complete the charging of the device.

[0151] In other embodiments, if some charging piles among multiple charging piles fail to unlock after a power outage, the control module continues to send power outage unlocking requests to the charging piles that failed to unlock after a power outage within a set time. If the control module receives a successful power outage unlocking message within the set time, it continues to execute step one above. If the control module does not receive a successful power outage unlocking message within the set time, it forcibly unlocks the charging piles that failed to unlock after a power outage to end charging. The control module can send a power outage unlocking failure message to the BMS of the electric vehicle and request power outage unlocking failure detection.

[0152] By implementing the above solution, after charging is complete, multiple power-off unlocking requests and monitoring can be performed on charging stations that fail to unlock due to power outages. This can improve the safety of the charging process, avoid energy waste, enhance the user experience, and provide reliable charging services.
