[0024] To illustrate the technical content, achieved objectives and effects of the present invention in detail, the following description is given in conjunction with the embodiments and accompanying drawings.

[0025] Please refer to Figures 1 to 4 A charging management method for new energy equipment supporting multiple charging guns at the same time includes the following steps:

[0026] S1. Receive a user's request for simultaneous charging at multiple charging piles, and determine all target charging piles selected by the user based on the request;

[0027] S2. Establish a virtual logical entity of a simulation pile, wherein the simulation pile obtains the maximum charging power of the new energy device by connecting the target charging pile to the new energy device;

[0028] S3. The simulation pile coordinates and distributes charging power to each of the target charging piles according to the maximum charging power, and simulates information interaction between a single pile and the EMS.

[0029] From the above description, it can be seen that the beneficial effects of the present invention are: a charging management method for new energy equipment that supports multi-gun charging at the same time of the present invention establishes a simulated pile virtual logical entity, coordinates the power distribution of the target charging pile, and uniformly dispatches multiple piles without the need to modify the original single-pile single-gun hardware, and realizes multi-pile collaborative charging at low cost; it can flexibly combine any number of pile lines in the station to break the fixed matching restrictions; at the same time, it disguises the upper platform as a single pile interaction, is compatible with the existing EMS system, is suitable for a variety of single BMS multi-charging port equipment, improves charging efficiency and disperses thermal management risks.

[0030] Furthermore, determining all target charging piles selected by the user according to the multi-charging request includes:

[0031] Determining the main charging pile selected by the user according to the multi-charging pile request;

[0032] In step S2, the simulation pile obtains the maximum charging power of the new energy device by connecting the target charging pile to the new energy device, including:

[0033] The simulation pile establishes a communication connection with the new energy device through the main charging pile, and obtains the maximum charging power of the new energy device through the established communication connection.

[0034] From the above description, it can be seen that the main pile is clearly responsible for communication and interaction with the vehicle's BMS (such as handshake and parameter acquisition), and the auxiliary pile is only responsible for power transmission, avoiding the complexity of simultaneous communication of multiple ports; adapting to the single BMS system architecture, no additional communication interface is required on the vehicle side, reducing modification costs; the main pile uniformly collects equipment requirements, provides an accurate basis for the simulation pile power distribution, and ensures the consistency and reliability of multi-pile collaboration.

[0035] Furthermore, the following steps are included between step S2 and step S3:

[0036] S21, the simulation pile performs insulation confirmation on the main charging pile, obtains the insulation confirmation result, and proceeds to step S3 only when the insulation test passes;

[0037] The insulation confirmation result is initiated by the main charging pile to the new energy device, and the new energy device generates it based on the line insulation detection with each target charging pile;

[0038] The target charging pile includes the main charging pile and other charging piles.

[0039] As can be seen from the above description, the insulation test of all target charging pile lines is carried out through the master pile to ensure the safety of the charging circuit and prevent risks such as leakage and short circuit. The test results are generated by the vehicle and fed back to the master pile, which meets the requirements of the national standard charging process. The hidden dangers of hardware failures are eliminated in advance to avoid interruptions due to insulation problems during the charging process, ensure the safety of equipment and personnel, and improve system stability.

[0040] Furthermore, the method further comprises the steps of:

[0041] S4. The simulation pile receives a power reduction request from one of the target charging piles, determines a power reduction quota according to the power reduction request, and adjusts the charging power of the remaining target charging piles that have not initiated the power reduction request according to the power reduction quota.

[0042] From the above description, it can be seen that when a charging pile needs to be derated due to factors such as temperature and failure, the simulated charging pile automatically adjusts the output power of the remaining charging piles to fill the gap and avoid charging interruption; it dynamically balances the load of multiple charging piles, giving priority to meeting the power needs of vehicles while extending the service life of the charging piles; it breaks the limitation of traditional fixed charging piles that "charging will be stopped if a single charging pile fails", and improves the utilization rate of station equipment and user experience.

[0043] Furthermore, step S3 includes:

[0044] The simulation pile distributes the maximum charging power evenly to all the target charging piles according to the maximum charging power, and the target charging piles supply power to the new energy equipment according to the distributed power.

[0045] As can be seen from the above description, in scenarios with the same pile capacity, the equal-sharing strategy simplifies the power allocation logic and improves scheduling efficiency; avoids the risk of overheating caused by overload of a single pile, balances the workload of multiple piles, and extends the overall life of the equipment; takes into account the vehicle's rapid charging needs and the balance of pile performance, adapts to the stable charging needs of large-capacity equipment, and reduces control complexity.

[0046] Please refer to Figure 5, a coordination device, comprising a processor, a memory, and a computer program stored in the memory and executable on the processor, wherein when the processor executes the computer program, the following steps are implemented:

[0047] S1. Receive a user's request for simultaneous charging at multiple charging piles, and determine all target charging piles selected by the user based on the request;

[0049] S3. The simulation pile coordinates and distributes charging power to each of the target charging piles according to the maximum charging power, and simulates information interaction between a single pile and the EMS.

[0050] From the above description, it can be seen that the beneficial effects of the present invention are: a coordination device of the present invention establishes a virtual logical entity of a simulated pile, coordinates the power distribution of the target charging pile, and uniformly dispatches multiple piles without the need to modify the original single-pile single-gun hardware, thereby realizing multi-pile collaborative charging at a low cost; it can flexibly combine any number of pile lines in the station, breaking the fixed matching restrictions; at the same time, it disguises itself as a single pile interaction to the upper platform, is compatible with the existing EMS system, is suitable for a variety of single-BMS multi-charging port devices, improves charging efficiency and disperses thermal management risks.

[0051] Furthermore, determining all target charging piles selected by the user according to the multi-charging request includes:

[0052] Determining the main charging pile selected by the user according to the multi-charging pile request;

[0053] In step S2, the simulation pile obtains the maximum charging power of the new energy device by connecting the target charging pile to the new energy device, including:

[0054] The simulation pile establishes a communication connection with the new energy device through the main charging pile, and obtains the maximum charging power of the new energy device through the established communication connection.

[0055] From the above description, it can be seen that the main pile is clearly responsible for communication and interaction with the vehicle's BMS (such as handshake and parameter acquisition), and the auxiliary pile is only responsible for power transmission, avoiding the complexity of simultaneous communication of multiple ports; adapting to the single BMS system architecture, no additional communication interface is required on the vehicle side, reducing modification costs; the main pile uniformly collects equipment requirements, provides an accurate basis for the simulation pile power distribution, and ensures the consistency and reliability of multi-pile collaboration.

[0056] Furthermore, the following steps are included between step S2 and step S3:

[0057] S21, the simulation pile performs insulation confirmation on the main charging pile, obtains the insulation confirmation result, and proceeds to step S3 only when the insulation test passes;

[0058] The insulation confirmation result is initiated by the main charging pile to the new energy device, and the new energy device generates it based on the line insulation detection with each target charging pile;

[0059] The target charging pile includes the main charging pile and other charging piles.

[0060] As can be seen from the above description, the insulation test of all target charging pile lines is carried out through the master pile to ensure the safety of the charging circuit and prevent risks such as leakage and short circuit. The test results are generated by the vehicle and fed back to the master pile, which meets the requirements of the national standard charging process.

[0061] Furthermore, the method further comprises the steps of:

[0062] S4. The simulation pile receives a power reduction request from one of the target charging piles, determines a power reduction quota according to the power reduction request, and adjusts the charging power of the remaining target charging piles that have not initiated the power reduction request according to the power reduction quota.

[0063] From the above description, it can be seen that when a charging pile needs to be derated due to factors such as temperature and failure, the simulated charging pile automatically adjusts the output power of the remaining charging piles to fill the gap and avoid charging interruption; it dynamically balances the load of multiple charging piles, giving priority to meeting the power needs of vehicles while extending the service life of the charging piles; it breaks the limitation of traditional fixed charging piles that "charging will be stopped if a single charging pile fails", and improves the utilization rate of station equipment and user experience.

[0064] Furthermore, step S3 includes:

[0065] The simulation pile distributes the maximum charging power evenly to all the target charging piles according to the maximum charging power, and the target charging piles supply power to the new energy equipment according to the distributed power.

[0066] As can be seen from the above description, in scenarios with the same pile capacity, the equal-sharing strategy simplifies the power allocation logic and improves scheduling efficiency; avoids the risk of overheating caused by overload of a single pile, balances the workload of multiple piles, and extends the overall life of the equipment; takes into account the vehicle's rapid charging needs and the balance of pile performance, adapts to the stable charging needs of large-capacity equipment, and reduces control complexity.

[0067] The present invention provides a charging management method and coordination device for new energy equipment that supports simultaneous charging of multiple guns, which is suitable for charging stations to adapt to simultaneous charging of multiple piles, and is particularly suitable for adapting to the charging needs of new energy equipment with multiple charging ports on a single BMS.

[0068] Please refer to Figures 1 to 4 , embodiment 1 of the present invention is:

[0069] A charging management method for new energy equipment supporting multiple charging guns simultaneously includes the following steps:

[0070] S1. Receive a user's request for simultaneous charging at multiple charging piles, and determine all target charging piles selected by the user based on the request;

[0071] Determining all target charging piles selected by the user according to the multi-charging request includes:

[0072] Determining the main charging pile selected by the user according to the multi-charging pile request;

[0073] In this embodiment, the user selects the charging pile and charging mode according to the operating rules of the charging station. The user can connect the charging gun according to the support design of his own new energy equipment, such as Figure 4 As shown, a device with three charging ports can connect to up to three charging piles. The user needs to report the selected charging pile to the system. For example, when using the scan code charging method, after the user scans the code of pile A with a mobile device, the display options of the mobile device include the option of charging with multiple piles at the same time. According to the user's selection, the charging mode is confirmed: if the option of charging with multiple piles at the same time is not selected, the original operating mode is used for normal charging. If the option of charging with multiple piles at the same time is selected, a simulation pile is created, and pile A is set as the main pile, and the user is prompted to select a coordinated charging pile (pile number).

[0074] Based on the information submitted by the user via the mobile terminal, all charging piles selected by the user are confirmed, namely the target charging piles. In this embodiment, for simplicity of description, the user selects two charging piles (one main charging pile A and a coordinated charging pile B) or three charging piles (one main charging pile A and coordinated charging piles B and C) as examples. In other equivalent embodiments, the user can select more charging piles for coordinated charging.

[0075] S2. Establish a virtual logical entity of a simulation pile, wherein the simulation pile obtains the maximum charging power of the new energy device by connecting the target charging pile to the new energy device;

[0076] In step S2, the simulation pile obtains the maximum charging power of the new energy device by connecting the target charging pile to the new energy device, including:

[0077] The simulation pile establishes a communication connection with the new energy device through the main charging pile, and obtains the maximum charging power of the new energy device through the established communication connection.

[0078] In this embodiment, refer to Figure 2 and Figure 3, using dual-charger collaboration as an example. A simulated charging pile is constructed, with the main charging gun of charging pile A exchanging messages with the vehicle's power transmission and reporting information to the simulated charging pile. The simulated charging pile determines the maximum power requirement of the vehicle (for example only; other new energy devices can be used in other equivalent embodiments) based on the information reported by charging pile A.

[0079] S21, the simulation pile performs insulation confirmation on the main charging pile, obtains the insulation confirmation result, and proceeds to step S3 only when the insulation test passes;

[0080] The insulation confirmation result is initiated by the main charging pile to the new energy device, and the new energy device generates it based on the line insulation detection with each target charging pile;

[0081] The target charging pile includes the main charging pile and other charging piles.

[0082] In this embodiment, refer to Figure 2 In the example timing diagram of dual-charger coordinated charging, the simulated charging pile requires a line insulation test before power distribution and charging pile activation. The main charging pile (charging pile A) and the new energy device perform a handshake to perform the insulation line test. Simultaneously, the new energy device performs insulation line tests with the remaining charging piles (such as charging pile B). The main charging pile then feeds back the insulation test results between the new energy device and each charging pile to the simulated charging pile.

[0083] After the insulation test is completed, proceed to the next steps.

[0084] S3. The simulation pile coordinates and distributes charging power to each of the target charging piles according to the maximum charging power, and simulates information interaction between a single pile and the EMS.

[0085] Step S3 includes:

[0086] The simulation pile distributes the maximum charging power evenly to all the target charging piles according to the maximum charging power, and the target charging piles supply power to the new energy equipment according to the distributed power.

[0087] In this embodiment, the simulation pile divides the power equally according to the maximum power demand of the vehicle when the capacities of the piles are the same. If the capacities of the piles are different, the charging power of the vehicle is met as much as possible without exceeding the safety of the vehicle's charging ports.

[0088] Each charging pile provides power to new energy equipment in real time according to the charging power setting issued by the simulation pile, and reports its own real-time charging data to the simulation pile.

[0089] Under normal circumstances, in order to ensure the charging needs of vehicles while taking into account the balance of the service life and performance of the charging pile, the power demand is generally divided equally among multiple charging piles.

[0090] The simulated piles summarize the real-time charging information of each pile and report it to the platform for subsequent settlement.

[0091] S4. The simulation pile receives a power reduction request from one of the target charging piles, determines a power reduction quota according to the power reduction request, and adjusts the charging power of the remaining target charging piles that have not initiated the power reduction request according to the power reduction quota.

[0092] In this embodiment, due to the existence of other strategies or the control strategy of the charging pile itself, for example, a pile in a collaborative operation needs to reduce its output because it is affected by the gun temperature, the ambient temperature inside the pile, etc., then the current maximum output capacity of the simulated pile is reported. After the simulated pile learns of it, it can adjust other collaborative piles to make up for the missing power to maximize the satisfaction of vehicle needs.

[0093] In this embodiment, for example, in a three-pole coordinated scenario, each vehicle port meets the national standard maximum of 250A, and the vehicle's maximum demand is 360A. Pile A, Pile B, and Pile C all have a capacity of 180kW and a maximum current of 250A. Based on the vehicle's real-time demand as measured by Pile A, the simulated pile distributes the current equally among the piles.

[0094] If the reported power of piles B and C needs to be reduced due to temperature or other factors, the simulation pile will lower the output settings of piles B and C and increase the output setting of pile A.

[0095] Please refer to Figure 5 , the second embodiment of the present invention is:

[0096] A coordination device 1 includes a processor 2, a memory 3, and a computer program stored in the memory 3 and runnable on the processor 2. When the processor 2 executes the computer program, the steps of the charging management method for new energy equipment supporting multi-gun simultaneous charging in the above embodiment 1 are implemented.

[0097] To sum up, the present invention provides a charging management method and coordination device for new energy equipment that supports multi-gun charging at the same time, establishes a simulated pile virtual logical entity, coordinates the power distribution of the target charging pile, and uniformly dispatches multiple piles without the need to modify the original single-pile single-gun hardware, thereby realizing multi-pile collaborative charging at low cost; it can flexibly combine any number of pile lines in the station, breaking the fixed matching restrictions; at the same time, it disguises itself as a single pile interaction to the upper platform, is compatible with the existing EMS system, is suitable for a variety of single-BMS multi-charging port devices, improves charging efficiency and disperses thermal management risks.

[0098] By adding a simulated charging station coordinator, this invention quickly achieves the goal of simultaneously charging two charging stations simultaneously, without modifying communication with the upstream platform or EMS. (A single BMS system for vehicles requires coordinated power allocation between two charging ports.) This eliminates the need for fixed device combinations, allowing for arbitrary coordination of charging stations within a specific area. This addresses the pain point of existing fixed charging stations being unable to simultaneously charge multiple stations when a device fails during maintenance.

[0099] This system allows for a rapid and minimal upgrade of existing fast-charging piles, supporting simultaneous charging of multiple piles per vehicle. It's ideal for quickly transitioning from smaller vehicle terminals to heavy trucks, buses, and logistics vehicles. The basic single-pile, single-charger hardware remains unchanged, while the software adds primary and auxiliary modes. Compatible with normal charging, this system allows for quick switching.

[0100] The addition of the simulation pile coordinator can flexibly call multiple piles in the station to achieve two guns, four guns, etc. on one vehicle; in addition, the arbitrary selection of piles in the main and auxiliary modes can avoid the fixed gun line position, which is more flexible. When the gun line is sufficient, the piles can be matched at will.

[0101] It is suitable for single BMS interactive system, but supports multi-gun simultaneous charging [multi-charging port] equipment applications; it is not limited to a fixed combination of two-gun equipment on one pile, it is flexible and can be expanded to charge multiple guns on one vehicle at the same time, suitable for aircraft, electric boats, heavy trucks, rail buses, etc., and large-capacity equipment applications.

[0102] There is no need to add additional high-cost modifications to the water cooling and charging port format, which disperses power input and simplifies control complexity.

[0103] The above descriptions are merely embodiments of the present invention and are not intended to limit the patent scope of the present invention. Any equivalent transformations made using the contents of the present invention's description and drawings, or directly or indirectly applied in related technical fields, are also included in the patent protection scope of the present invention.
