Description

Technical Field

[0001] The present application relates to the field of new energy charging and battery replacement technology, and in particular to a method, device and computer equipment for intelligent power switching of a ring charging pile. Background Art

[0002] With the development of new energy vehicle technology, electric vehicle charging and battery replacement technology has emerged. As the energy supply equipment of electric vehicles, the rationality and reliability of the design of the charging stack are of great significance.

[0003] At present, the existing matrix DC fully flexible charging stacks and charging methods with dynamic power distribution on the market adopt a fixed power plus dynamic power distribution adjustable method. This method can not only charge the car with maximum efficiency, but also greatly reduce the power consumption of the charging stack itself, and can meet the charging needs of electric vehicles with different energy storage battery capacities and different charging rates; in addition, when the power demand exceeds the rated power, the existing charging stacks generally stop charging subsequent vehicles, or reduce the power of the first charged vehicle to charge the subsequent vehicles.

[0004] However, the aforementioned fully flexible DC charging stack solution is relatively expensive, leading most scenarios to use a relatively low-cost ring topology charging stack solution. However, ring topologies typically use a fixed power switching pattern, resulting in irrational power distribution and an inability to meet diverse charging needs. Summary of the Invention

[0005] Based on this, it is necessary to provide a fully automatic power switching method, device and computer equipment for a ring charging stack to address the above technical problems.

[0011] After each candidate power module is determined, the system checks whether the current charging power gap is greater than the output charging power of the candidate power module determined this time. If so, the system controls the candidate power module determined this time to output charging power to the target power module, and determines the next candidate power module in the power supply order.

[0012] The charging power gap is the difference between the required power of the target charging gun and the outputtable charging power of the target power module and the outputtable charging power of the candidate power module determined before this time.

[0022] In one embodiment, the first detected power supply module that meets the power switching condition is selected as the next candidate power supply module, including:

[0023] Get the target direction used when determining the candidate power module last time;

[0024] The opposite direction of the target direction used when the candidate power module was determined last time is used as the target direction used when the candidate power module is determined this time.

[0025] In one embodiment, the target direction opposite to the target direction used in the previous determination of the candidate power module is used as the target direction used in the current determination of the candidate power module, including:

[0026] The target direction used in determining the candidate power modules this time is one of a clockwise direction and a counterclockwise direction.

[0027] In one embodiment, detecting whether there is a target charging gun, the target charging gun's required power being greater than the charging power outputtable by a target power module, and the target power module being connected to the target charging gun, includes:

[0028] The required charging power of the target charging gun is the largest among the required charging powers of all charging guns.

[0034] If the target charging gun exists, starting from the power module directly connected to the target power module, according to a pre-set power supply sequence, all or part of the multiple power modules are controlled to output charging power to the target power module, so that the target power module supplies power to the target charging gun based on the charging power of the target power module itself and the charging power input by other power modules.

[0035] In a fourth aspect, the present application further provides a computer-readable storage medium having a computer program stored thereon, which, when executed by a processor, implements the following steps:

[0036] Detecting whether there is a target charging gun, the target charging gun's required power is greater than the charging power that can be output by the target power module, and the target power module is connected to the target charging gun;

[0037] If the target charging gun exists, starting from the power module directly connected to the target power module, according to a pre-set power supply sequence, all or part of the multiple power modules are controlled to output charging power to the target power module, so that the target power module supplies power to the target charging gun based on the charging power of the target power module itself and the charging power input by other power modules.

[0040] If the target charging gun exists, starting from the power module directly connected to the target power module, according to a pre-set power supply sequence, all or part of the multiple power modules are controlled to output charging power to the target power module, so that the target power module supplies power to the target charging gun based on the charging power of the target power module itself and the charging power input by other power modules.

[0041] The aforementioned method, device, and computer equipment for intelligent power switching of a ring-shaped charging stack detect whether there is a target charging gun with a required power greater than the output power of the target charging module. If so, the method controls all or some of the multiple power modules, starting with the power module directly connected to the target power module, to output charging power to the target power module in a pre-set power supply sequence. This solution, in conjunction with this solution, takes into account the current high cost of fully flexible charging solutions for DC charging stacks and automatically switches the charging power of the charging system based on the required charging power of the target charging gun, thereby reducing flexible switching costs and maximizing power.

[0050] In order to make the purpose, technical solutions and advantages of this application more clear, the following further describes this application in detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain this application and are not intended to limit this application.

[0051] The ring charging stack power intelligent switching method provided in the embodiment of the present application can be applied to Figure 1 In the application environment shown, the terminal 102 communicates with the charging system 104 via the network to detect whether a target charging gun that meets the conditions exists. Furthermore, starting with the power module directly connected to the target power module, all or some of the multiple power modules are controlled to output charging power to the target power module in accordance with a pre-set power supply sequence. The data storage system can store relevant data that the charging system 104 needs to detect whether a target charging gun that meets the conditions exists. The data storage system can be integrated with the charging system 104 or placed in the cloud or other network server.

[0052] Terminal 102 may include, but is not limited to, various personal computers, laptops, smartphones, tablets, IoT devices, and portable wearable devices. IoT devices may include smart speakers, smart TVs, smart air conditioners, and smart car devices. Portable wearable devices may include smart watches, smart bracelets, and head-mounted devices. Charging system 104 may be implemented using a standalone server or a server cluster consisting of multiple servers.

[0053] In one embodiment, Figure 2 As shown, a method for intelligent switching of power of a ring charging pile is provided. Figure 1 The following steps are used as an example to illustrate the process of terminal 102:

[0054] S201, detecting whether there is a target charging gun, the target charging gun's required power is greater than the charging power output by the target power module, and the target power module is connected to the target charging gun;

[0055] In this embodiment, the target charging gun is a charging gun whose required charging power is greater than the charging power output of the power module directly connected to the charging gun. Accordingly, the target power module is the power module directly connected to the target charging gun.

[0056] Specifically, in the process of detecting whether a target charging gun exists, this embodiment can use a charging system to obtain the required charging power of the target charging gun and the charging power that can be output by the target power module directly connected to the target charging gun, and then compare them. If the charging system detects that the required charging power of the target charging gun is less than or equal to the charging power that can be output by the target power module, it can be determined that the target charging gun does not exist, that is, there is no need to adopt the ring charging stack power intelligent switching method of the present invention. If the charging system detects that the required charging power of the target charging gun is greater than the charging power that can be output by the target power module, it is detected that a target charging gun exists, and it is necessary to adopt the ring charging stack power intelligent switching method of the present invention, that is, proceed to the next step.

[0057] S202, if the target charging gun exists, starting from the power module directly connected to the target power module, according to a pre-set power supply sequence, control all or part of the multiple power modules to output charging power to the target power module, so that the target power module supplies power to the target charging gun based on the charging power of the target power module itself and the charging power input by other power modules.

[0058] Optionally, if the target charging gun exists, then based on a pre-set power supply sequence, starting from the power module directly connected to the target power module, a comprehensive analysis can be performed on each power module included in the charging system to determine whether each power module can output charging power to the target power module.

[0059] Specifically, if a power module is determined to be unable to output charging power to the target power module, this power module is bypassed and the next power module is determined to be able to output charging power to the target power module according to the pre-set power supply order. Furthermore, the target charging gun is charged using the power modules that have been determined to be able to output charging power to the target power module, based on the target power module's own charging power and the charging power input from the other determined power modules.

[0060] In the aforementioned intelligent power switching method for a ring-shaped charging stack, a target charging gun is determined. Further, according to a pre-set power supply sequence, all or some of the multiple power modules in the charging system are controlled to output charging power to the target power module. This enables the target power module to charge the target charging gun based on its own charging power and the charging power input from other power modules, thereby achieving automatic power distribution. This embodiment automatically switches the charging power of the charging system based on the required charging power of the target charging gun, reducing flexible switching costs and maximizing the charging power in the charging system.

[0061] In one embodiment, Figure 3 As shown, the above S202 is further refined. Specifically, the following steps may be included:

[0062] S301 , starting from the power module directly connected to the target power module, candidate power modules are determined from a plurality of power modules in sequence according to a power supply order.

[0063] In this embodiment, based on a pre-defined power supply sequence, a comprehensive analysis is performed on each power module included in the charging system, starting with the power module directly connected to the target power module, to determine whether each power module meets the conditions for outputting charging power to the target power module. Furthermore, if the current power module does not meet the conditions for outputting charging power to the target power module, the current power module is skipped and the next power module is further evaluated according to the pre-defined power supply sequence to determine whether it meets the conditions for outputting charging power to the target power module. Specifically, the current power module is only selected as a candidate power module if it meets the conditions for outputting charging power to the target power module.

[0064] S302, after each determination of a candidate power module, detect whether the current charging power gap is greater than the output charging power of the candidate power module determined this time. If so, control the candidate power module determined this time to output charging power to the target power module, and determine the next candidate power module according to the power supply order.

[0065] In this embodiment, in the process of detecting the current charging power gap, the charging system can be used to obtain the required charging power of the target charging gun and the charging power currently obtained by the target charging gun, and then compare them. If the charging power currently obtained by the target charging gun is equal to or greater than the required charging power of the target charging gun, then the required power of the target charging gun has been met, that is, there is no power charging gap, and there is no need to determine the candidate power module, nor is there any need to control the charging power output by the candidate power module determined this time to the target power module; if the charging power currently obtained by the target charging gun is less than the required charging power of the target charging gun, it is determined that there is a charging power gap, and it is necessary to control the candidate power module determined this time to output charging power to the target power module, and determine the next candidate power module according to the power supply order. Furthermore, if the charging power gap is greater than the maximum charging power that can be provided by the candidate power module determined this time, it is necessary to continue to determine the next candidate power module according to the power supply order.

[0066] S303, wherein the charging power gap is the difference between the required power of the target charging gun and the outputtable charging power of the target power module and the outputtable charging power of the candidate power module determined before this time.

[0067] Specifically, in this embodiment, during the process of detecting the current charging power gap, the charging system may obtain the required charging power of the target charging gun, the outputtable charging power of the target power module, and the outputtable charging power of previously determined candidate power modules, and then compare them. If the required charging power of the target charging gun is less than the outputtable charging power of the target power module and the outputtable charging power of the previously determined candidate power modules, there is no charging power gap, i.e., the current power module is not required to output charging power to the target charging gun, and the determination of the next candidate power module can be stopped. If the required charging power of the target charging gun is greater than the outputtable charging power of the target power module and the outputtable charging power of the previously determined candidate power modules, the required charging power of the target charging gun is subtracted from the outputtable charging power of the target power module and the outputtable charging power of the previously determined candidate power modules, and the obtained difference is the charging power gap. Furthermore, the currently determined candidate power module is controlled to output charging power to the target power module, and the next candidate power module is determined according to the power supply order.

[0068] It is understandable that in the process of determining the candidate power module, the charging system detects the required charging power of the target charging gun, the output charging power of the target power module, and the output charging power of the candidate power module that has been determined before this time, and calculates the charging power gap. Furthermore, by comparing the charging power gap with the maximum charging power that can be provided by the candidate power module determined this time, it is determined whether it is necessary to continue to determine the next candidate power module. This embodiment determines whether the next candidate power module is needed to continue to supply power to the target charging gun based on the calculated charging power gap, thereby realizing automatic charging power switching of the charging system, reducing the cost of the flexible charging stack, and maximizing the use of the charging power in the charging system.

[0069] In one embodiment, the above S302 is further refined, which may include:

[0070] If not, the candidate power module determined this time is controlled to output charging power to the target power module, and the determination of the next candidate power module is stopped.

[0071] Specifically, the charging system detects the current charging power gap and the maximum charging power that can be provided by the candidate power module determined this time, and compares the two. If the detected current charging power gap is less than the output charging power of the candidate power module determined this time, then it can be understood that the output charging power of the candidate power module determined this time can meet the charging power gap required by the target charging gun, that is, there is no need to determine the next candidate power module according to the power supply order. Furthermore, the charging system controls the candidate power module determined this time to output the charging power required by the target charging gun to the target power module to supplement the current charging power gap of the target charging gun.

[0072] It can be understood that this embodiment controls the candidate power module determined this time to output charging power to the target power module, supplements the current charging power gap of the target charging gun, achieves the charging power required by the target charging gun, and stops determining the next candidate power module, thereby realizing intelligent switching of charging power according to the requirements of the target charging gun in the charging system to meet the diversified charging needs.

[0073] In one embodiment, Figure 4 As shown, the above S302 is further refined. Specifically, the following steps may be included:

[0074] S401 , starting from the candidate power module determined this time, the power modules are sequentially detected along the target direction of the ring loop to see whether they meet the power switching conditions.

[0075] In this embodiment, when determining the next candidate power module, the charging system sequentially tests each power module along the target direction of the loop, starting from the currently determined candidate power module, to determine whether it meets the power switching conditions. Specifically, if the currently tested power module meets the power switching conditions, it is determined as a candidate power module. If the currently tested power module does not meet the power switching conditions, it is skipped and the next power module along the target direction of the loop is tested to determine whether it meets the power switching conditions.

[0076] S402: The first detected power module that meets the power switching condition is used as the next candidate power module.

[0077] Specifically, when the charging system detects the power modules in sequence along the target direction of the ring loop, if the first power module detected in sequence meets the power switching conditions, then this power module will be used as the next candidate power module, waiting to supply charging power to the target charging gun; if the current power module detected in sequence does not meet the power switching conditions, then the next power module will be detected along the direction of the ring loop until a power module is detected that meets the power switching conditions, then this power module will be used as the next candidate power module, waiting to supply charging power to the target charging gun.

[0078] As can be understood, this embodiment sequentially detects whether power modules meet the power switching conditions along the target direction of the loop, thereby determining the next candidate power module. The first power module detected that meets the power switching conditions is selected as the first candidate power module and supplies power to the target charging gun. This embodiment implements intelligent switching of charging power based on the required charging power of the target charging gun, maximizing the charging power in the charging system and meeting charging diversity requirements.

[0079] In one embodiment, the power switching condition mentioned in S401 is further refined. The power switching condition should include any one of the following conditions:

[0080] The connected charging gun is not in operation. Specifically, the charging gun connected to the power module does not need to output charging power; its output charging power is the total charging power available to the power module. If the output charging power of the power module is less than the total charging power available to the power module, the power module is considered to be in operation. This means that the charging module does not meet this condition, and the charging system will follow the next target direction of the loop to determine whether the next power module meets the power switching conditions.

[0081] It is not the target power module. Specifically, when sequentially detecting power modules along the target direction of the loop to see if they meet the power switching conditions, when detecting the next power module, it should first be determined whether the power module is the target power module connected to the target charging gun. If it is determined that the next power module along the target direction of the loop is the target power module connected to the target charging gun, the target power module is skipped, the target direction of the loop is not changed, and the determination of whether the next power module meets the power switching conditions continues.

[0082] It is not a candidate power module that has already been determined. Specifically, when sequentially detecting power modules along the target direction of the loop to see if they meet the power switching conditions, when detecting the next power module, it should first be determined whether the power module is a candidate power module that has already been determined. If it is determined that the next power module along the target direction of the loop is a candidate power module that has already been determined, the candidate module is skipped, the target direction of the loop is not changed, and the determination of whether the next power module meets the power switching conditions continues.

[0083] It will be appreciated that this embodiment determines the order in which candidate power modules in the charging system are to be supplied with charging power by determining whether each power module meets the power switching conditions. Based on whether a power module meets any of the power switching conditions, it is inferred whether the power module can serve as a candidate power module and provide charging power to the target charging gun. In the charging system, this embodiment can quickly determine whether each power module can serve as a candidate power module based on its own conditions, making the intelligent switching method for demand charging power more rapid and agile.

[0084] In one embodiment, Figure 5 As shown, the above S401 is further refined. Specifically, the following steps may be included:

[0085] S501: Obtain the target direction used in the last determination of the candidate power module.

[0086] In this embodiment, the target direction used by the charging system when determining the candidate power module is divided into a clockwise direction or a counterclockwise direction. During the process of the charging system determining the candidate power module last time, the charging system can obtain whether the target direction used when determining the candidate module last time is clockwise or counterclockwise, and store this target direction for use when determining the candidate power module this time.

[0087] S502 : Using the opposite direction of the target direction used in the previous determination of the candidate power module as the target direction used in the current determination of the candidate power module.

[0088] Specifically, during the current charging system's process of determining a candidate power module, the charging system will obtain the target direction used when the candidate power module was previously determined, and use the opposite direction of the target direction used when the candidate power module was previously determined as the target direction used when the candidate power module was currently determined. If the target direction used when the candidate power module was previously determined was left, then the target direction used when the candidate power module was currently determined should be right; if the target direction used when the candidate power module was previously determined was right, then the target direction used when the candidate power module was currently determined should be left.

[0089] It can be understood that the charging system follows the target direction of the loop, skipping power modules that do not meet the power switching conditions, identifying candidate power modules, and providing charging power to the target charging station. In this embodiment, the charging system can quickly determine the direction of the next candidate power module based on the specific conditions of each power module, making the candidate power module identification process more efficient and improving the efficiency of the required charging power intelligent switching method.

[0090] In one embodiment, the above S502 is further refined, with the specific feature that the target direction used in determining the candidate power module this time is one of a clockwise direction and a counterclockwise direction.

[0091] The target direction set by the present invention is that the counterclockwise direction takes precedence over the clockwise direction, that is, the power module adjacent to the target power module or the last determined candidate power module in the counterclockwise direction is given priority. If the power module adjacent to the target power module or the last determined candidate power module in the counterclockwise direction does not meet the power switching condition, the power module adjacent to the target power module or the last determined candidate power module in the clockwise direction is considered. It is understandable that in the process of determining the candidate power module, whether it is the power module adjacent to the target power module or the last determined candidate power module in the counterclockwise direction or the power module adjacent to the target power module or the last determined candidate power module in the clockwise direction, the power module adjacent to the target unit module or the last determined candidate power module should be given priority to ensure that the charging power in the charging system is maximized and that the charging power can be provided to the target power module more quickly.

[0092] In one embodiment, the present invention further defines the method for intelligently switching the power of a ring charging stack, specifically, that the required charging power of the target charging gun is the largest among the required charging powers of all charging guns.

[0093] Specifically, before the charging system performs intelligent switching of the charging power for the target power module, the charging system will first obtain the required charging power of each charging gun, compare the required charging power of each charging gun, determine the charging gun with the largest required charging power, and set it as the target charging gun. The ring charging stack power intelligent switching method of the present invention is only for the target charging gun, and the required charging power of other charging guns in the charging system is not considered. It can be understood that this embodiment only performs intelligent switching of the charging power for the target charging gun, which can adapt to various complex charging scenarios and maximize the utilization of the charging power of the charging system.

[0094] It is to be understood that, although the various steps in the flowcharts involved in the various embodiments described above are displayed in sequence as indicated by the arrows, these steps are not necessarily performed in sequence in the order indicated by the arrows. Unless otherwise specified herein, there is no strict order restriction on the execution of these steps, and these steps can be performed in other orders. Moreover, at least a portion of the steps in the flowcharts involved in the various embodiments described above can include multiple steps or multiple stages, and these steps or stages are not necessarily performed at the same time, but can be performed at different times, and the execution order of these steps or stages is not necessarily performed in sequence, but can be performed in turn or alternately with other steps or at least a portion of steps or stages in other steps.

[0095] Based on the same inventive concept, embodiments of the present application also provide a ring-shaped charging stack power intelligent switching device for implementing the aforementioned ring-shaped charging stack power intelligent switching method. The solution provided by this device is similar to the solution described in the aforementioned method. Therefore, the specific limitations of one or more embodiments of the ring-shaped charging stack power intelligent switching device provided below can be found in the limitations of the ring-shaped charging stack power intelligent switching method described above and will not be repeated here.

[0107] The first detected power supply module that meets the power switching condition is used as the next candidate power supply module.

[0108] Each module in the aforementioned ring-shaped charging stack intelligent power switching device can be implemented in whole or in part through software, hardware, or a combination thereof. Each module can be embedded in or independent of a processor in a computer device in hardware form, or can be stored in a computer device memory in software form, so that the processor can call and execute the corresponding operations of each module.

[0109] In one embodiment, a computer device is provided. The computer device may be a server, and its internal structure diagram may be as follows: Figure 8 As shown. The computer device includes a processor, a memory and a network interface connected via a system bus. The processor of the computer device is used to provide computing and control capabilities.

The internal memory provides an environment for the operation of the operating system and the computer program in the non-volatile storage medium.
