Transformer-powered charging system, charging method, and readable storage medium

Abstract

This invention belongs to the field of power distribution technology, specifically relating to a transformer-powered charging system, charging method, and readable storage medium. The charging system includes a control module, a transformer, a power distribution module, and several charging piles. The control module allocates corresponding output power to the new user through the power distribution module. When the control module detects that any new user has been activated, if the remaining output power of the transformer is less than the required charging power data in the charging request information, it calls upon the output power of at least one existing user or at least one other new user to allocate it to the new user. This invention, while minimizing the impact on the charging power of existing users, ensures that new users have sufficient charging power to build complete charging behavior information for inclusion in the database. This allows for continuous optimization of the transformer's allocation strategy, enabling the addition of more charging piles while maintaining the existing power supply, with each charging pile achieving optimal charging efficiency for the target user.

Description

Technical Field

[0001] This invention belongs to the field of power distribution technology, specifically relating to power distribution systems, and more particularly to a transformer-powered charging system, charging method, and readable storage medium. Background Technology

[0002] Charging stations require transformers for power distribution, which can cause the total rated power of the charging stations to exceed the transformer's maximum capacity. To address this issue, existing transformer power distribution systems dynamically adjust the output power of each charging station based on the historical usage habits of charging station users, thereby indirectly adjusting the charging power of users and achieving a more rational allocation of transformer power.

[0003] However, when a new user uses a charging station, the transformer power allocation system lacks records of that new user's historical usage habits, preventing it from incorporating them into a scheduling strategy based on those habits. In this situation, the power is already occupied by other charging stations that match the user's preferences. Consequently, the charging station used by the new user cannot quickly reach an efficient charging state and must wait for the transformer capacity to be released before increasing its charging power.

[0004] Therefore, there is an urgent need to develop a new transformer-powered charging system, charging method, and readable storage medium to solve the technical problem that the existing transformer power scheduling strategy based on historical usage habits cannot meet the high power allocation needs of new users when they connect to charging piles.

[0005] It should be noted that the information disclosed in this background section is only for understanding the background technology of the present application concept, and therefore, the above description is not considered to constitute prior art information. Summary of the Invention

[0006] This disclosure provides at least one transformer-powered charging system, charging method, and readable storage medium.

[0007] In a first aspect, embodiments of this disclosure provide a transformer-powered charging system, comprising: a control module, a transformer, a power distribution module, and several charging piles; wherein the input end of the transformer is connected to the power grid, the input end of the power distribution module is electrically connected to the output end of the transformer, and the input end of each charging pile is electrically connected to the output end of the power distribution module; the power distribution module and each charging pile are electrically connected to the control module; the control module is configured to obtain corresponding charging request information through each charging pile, and when searching in the database for charging behavior habit information that matches the identity code in the charging request information, temporarily mark the charging pile corresponding to the charging request information as the original user; if the control module does not find the identity code in the charging request information in the database... If the charging request information matches the user's charging behavior habits and the battery percentage data in the charging request information is lower than a first percentage threshold, the control module temporarily marks the charging pile corresponding to the charging request information as a new user. When the new user is activated, if the remaining output power of the transformer is not less than the required charging power data in the charging request information, the control module is further configured to allocate the corresponding output power to the new user according to the required charging power data in the charging request information through the power allocation module. If the remaining output power of the transformer is less than the required charging power data in the charging request information, the control module is further configured to allocate the output power allocated to at least one original user and / or at least one new user from a previous time to the new user at the current time through the power allocation module.

[0008] In an optional implementation, the control module is further configured to call the output power of at least one original user or at least one new user from a past moment through the power allocation module, comprising: the control module is further configured to calculate the battery percentage data of the original user at the current moment based on charging behavior habit information; the control module is further configured to calculate a callable threshold based on the battery percentage data of each original user at the current moment; when the battery percentage data of any original user at the current moment is greater than the callable threshold, the control module calculates the callable power corresponding to that original user; the control module is further configured to transfer the callable power from any original user to the corresponding new user through the power allocation module.

[0009] In one optional implementation, the callable threshold is the average of the battery percentage data of all original users at the current moment; the callable power = the battery percentage data of the original user at the current moment * the charging power corresponding to the battery percentage data in the charging behavior habit information of the original user in the database.

[0010] In an optional implementation, the control module is further configured to transfer the available power from any original user to the corresponding new user via the power allocation module, comprising: the control module being configured to sort the available power according to its magnitude; the control module being further configured to sequentially add each available power to the remaining output power of the transformer, and compare it with the required charging power data in the charging request information, until the sum of any available power and the remaining output power of the transformer is not less than the required charging power data in the charging request information; the control module being further configured to transfer the corresponding available power to the corresponding new user via the power allocation module, and simultaneously the control module being further configured to allocate a portion of the remaining output power to the new user via the power allocation module, until the actual output power of the new user is equal to the required charging power data in the charging request information.

[0011] In an optional implementation, the control module is further configured to call the output power of at least one original user or at least one new user from a past time through the power allocation module. The method further includes: when the control module detects that a new user is enabled at the current time and at least two new users were enabled in the past time, and the callable power of each original user is respectively allocated to the corresponding new user from the past time, the control module is further configured to extract the output power of each new user from the past time to the new user at the current time through the power allocation module.

[0012] In an optional implementation, the control module is further configured to extract the output power of new users at each past time point to the new user at the current time point through the power allocation module. The method includes: the control module is configured to acquire battery percentage data of new users at each past time point; the control module is configured to calculate the extracted power of new users at each past time point based on the battery percentage data of new users at each past time point; the control module is further configured to allocate the extracted power of new users at each past time point to the new user at the current time point through the power allocation module until the actual output power of the new user at the current time point is equal to the charging power data required in the charging request information.

[0013] In one alternative implementation, the power extracted by a new user at any past moment = the contribution ratio of the new user at that past moment * the charging power required by the new user at the current moment; the contribution ratio of a new user at any past moment = the battery percentage data of the new user at that past moment ÷ the sum of the battery percentage data of all new users at all past moments.

[0014] In one alternative implementation, the remaining output power of the transformer = the maximum output power of the transformer - the total output power of each of the charging piles at the current moment.

[0015] Secondly, embodiments of this disclosure also provide a charging method using the charging system described above, comprising: a control module acquiring corresponding charging request information through each charging pile; when the control module finds charging behavior habit information matching the identity code in the charging request information in the database, the control module temporarily marks the charging pile corresponding to the charging request information as the original user; when the control module does not find charging behavior habit information matching the identity code in the charging request information in the database, and the battery percentage data in the charging request information is lower than a first percentage set threshold, the control module temporarily marks the charging pile corresponding to the charging request information as a new user; when the control module detects any new user being activated at the current moment, and the remaining output power of the transformer is not less than the required charging power data in the charging request information, the control module allocates the corresponding output power to the new user according to the required charging power data in the charging request information through the power allocation module; when the control module detects any new user being activated at the current moment, and the remaining output power of the transformer is less than the required charging power data in the charging request information, the control module calls the output power of at least one original user or at least one new user from a past moment through the power allocation module to allocate it to the new user at the current moment.

[0016] Thirdly, embodiments of this disclosure also provide a computer-readable storage medium having computer program instructions stored thereon, characterized in that the computer program instructions can be executed by a processor to implement the method as described above.

[0017] The beneficial effects of this invention are that, when the charging target is determined to be an existing user based on the charging request information, the invention charges the existing user using the existing charging behavior information in the database. Simultaneously, when the charging target is determined to be a new user based on the charging request information, if the remaining output power of the transformer is not less than the charging power required by the new user, the output power is directly allocated to the new user. If the remaining output power of the transformer is less than the charging power required by the new user, the invention ensures that the new user has sufficient charging power to build complete charging behavior information to be added to the database, while minimizing the impact on the original user's charging power. This allows for continuous optimization of the transformer allocation strategy, enabling the addition of more charging piles while maintaining the existing power supply, and ensuring optimal charging efficiency for each charging pile for the target user.

[0025] Research has revealed that with the increasing number of new energy vehicles, older residential areas also require a continuous addition of charging stations. Simultaneously, all charging stations require transformers for power distribution, causing the total rated power of the charging stations to exceed the maximum capacity of the transformers. To address this issue, existing transformer power allocation systems dynamically adjust the output power of each charging station based on users' historical usage habits, thereby indirectly adjusting the charging power of users and achieving a rational allocation of transformer power. However, when a new user uses a particular charging station, the transformer power allocation system lacks records of that new user's historical usage habits and cannot incorporate them into the historical usage-based scheduling strategy. In this situation, the charging station's output power is very low, and the new user receives only a small charging power, making it difficult to quickly enter a high-efficiency charging state. They must wait for the transformer capacity to be released before the charging power can be increased.

[0026] Based on the above research, this disclosure provides a transformer-powered charging system, charging method, and readable storage medium. When the charging target is determined to be an existing user based on the charging request information, the system charges the existing user using existing charging behavior information in the database. Simultaneously, when the charging target is determined to be a new user based on the charging request information, if the remaining output power of the transformer is not less than the charging power required by the new user, the system directly allocates output power to the new user. If the remaining output power of the transformer is less than the charging power required by the new user, the system ensures that the new user has sufficient charging power to build complete charging behavior information to be added to the database, while minimizing the impact on the charging power of the existing user. This ensures continuous optimization of the transformer allocation strategy, enabling the addition of more charging piles while maintaining the existing power supply, and achieving optimal charging efficiency for each charging pile for the charging target.

[0027] The shortcomings of the above solutions are the result of the inventor's practical experience and careful research. Therefore, the discovery process of the above problems and the solutions proposed in this disclosure below should be considered as the inventor's contribution to this disclosure.

[0028] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0029] The following detailed description of some embodiments of the present invention is provided in conjunction with the accompanying drawings. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0030] like Figures 1 to 5 At least one embodiment provides a transformer-powered charging system, comprising: a control module, a transformer, a power distribution module, and several charging piles; wherein the input end of the transformer is connected to the power grid, the input end of the power distribution module is electrically connected to the output end of the transformer, and the input end of each charging pile is electrically connected to the output end of the power distribution module; the power distribution module and each charging pile are electrically connected to the control module; the control module is configured to obtain corresponding charging request information through each charging pile, and when searching in the database for charging behavior habit information that matches the identity code in the charging request information, temporarily mark the charging pile corresponding to the charging request information as the original user; if the control module does not find a matching identity code in the database... If the charging behavior habit information is matched and the battery percentage data in the charging request information is lower than a first percentage set threshold, the control module temporarily marks the charging pile corresponding to the charging request information as a new user; when the new user is activated, if the remaining output power of the transformer is not less than the required charging power data in the charging request information, the control module is also configured to allocate the corresponding output power to the new user according to the required charging power data in the charging request information through the power allocation module; and if the remaining output power of the transformer is less than the required charging power data in the charging request information, the control module is also configured to allocate the output power allocated to at least one original user and / or at least one new user in the past to the new user at the current moment through the power allocation module.

[0031] Specifically, please refer to Figure 1 Solid lines represent power lines, and dashed lines represent control lines.

[0032] Specifically, the charging stations corresponding to the original user, the current new user, and the new user in the past are still in the charging state. The new user in the past refers to the charging station that is still in the charging state but the corresponding charging behavior habit information has not yet been built into the database.

[0033] Specifically, when the control module does not find charging behavior habit information matching the identity code in the charging request information in the database, and the battery percentage data in the charging request information is not lower than the first percentage set threshold, the control module temporarily marks the charging pile corresponding to the charging request information as a temporary user.

[0034] Specifically, when the control module detects that any temporary user is enabled at the current moment, the control module allocates a fixed output power to the temporary user through the power distribution module.

[0035] Specifically, the first percentage threshold can be set to any one of 70%, 75%, 80%, or 85%.

[0036] Specifically, the control module can be, but is not limited to, an industrial server.

[0037] In at least one embodiment, when the charging target is determined to be an existing user based on the charging request information, the existing user is charged using the existing charging behavior information in the database. Simultaneously, when the charging target is determined to be a new user based on the charging request information, if the remaining output power of the transformer is not less than the charging power required by the new user, the output power is directly allocated to the new user. If the remaining output power of the transformer is less than the charging power required by the new user, the system ensures that the new user has sufficient charging power to build complete charging behavior information to be added to the database, while minimizing the impact on the charging power of the existing user. This ensures that the transformer allocation strategy is continuously optimized, allowing for the addition of more charging piles while maintaining the existing power supply, and ensuring that each charging pile has the best charging efficiency for the charging target.

[0038] In at least one embodiment, the control module is further configured to call the output power of at least one original user or at least one new user from a past moment through the power allocation module, comprising: the control module is further configured to calculate the battery percentage data of the original user at the current moment based on charging behavior habit information; the control module is further configured to calculate a callable threshold based on the battery percentage data of each original user at the current moment; when the battery percentage data of any original user at the current moment is greater than the callable threshold, the control module calculates the callable power corresponding to that original user; the control module is further configured to transfer the callable power from any original user to the corresponding new user through the power allocation module.

[0039] Specifically, based on charging behavior information, the system filters out users who exceed the available power threshold at the current moment and then calculates the corresponding available power.

[0040] In at least one embodiment, the callable threshold is the average of the battery percentage data of all original users at the current moment; the callable power = the battery percentage data of the original user at the current moment * the charging power corresponding to the battery percentage data in the charging behavior habit information of the original user in the database.

[0041] Specifically, the callable threshold = the sum of the battery percentage data of all original users at the current moment ÷ the number of all original users.

[0042] Specifically, the threshold can be dynamically calculated based on charging behavior habits.

[0043] Specifically, the original users who need to be forced to use the called power are filtered according to the callable threshold. The original users who exceed the callable threshold are sorted from high to low according to the battery percentage data (SOC). The callable power of each original user can be calculated based on the battery percentage data (SOC).

[0044] Specifically, if the calculated callable threshold is 80%, and the battery percentage of original user 1 at the current moment is 90%, and the charging power corresponding to this battery percentage data in the charging behavior information of original user 1 in the database is 7KW, then the callable power of original user 1 is 6.3KW.

[0045] Specifically, if the calculated callable threshold is 80%, and the battery percentage of original user #2 at the current moment is 80%, and the charging power corresponding to this battery percentage data in the charging behavior information of original user #2 in the database is 7KW, then the callable power of original user #2 is 5.6KW.

[0046] In at least one embodiment, the control module is further configured to transfer the available power from any original user to the corresponding new user via the power allocation module, comprising: the control module being configured to sort the available power according to its magnitude; the control module being further configured to sequentially add each available power to the remaining output power of the transformer, and compare it with the required charging power data in the charging request information, until the sum of any available power and the remaining output power of the transformer is not less than the required charging power data in the charging request information; the control module being further configured to transfer the corresponding available power to the corresponding new user via the power allocation module, and simultaneously the control module being further configured to allocate a portion of the remaining output power to the new user via the power allocation module, until the actual output power of the new user is equal to the required charging power data in the charging request information.

[0047] Specifically, based on the order of available power, if the sum of the available power of a single original user and the remaining output power of the transformer is greater than the charging power required by the new user at the current moment, the control module will allocate the available power of the single original user and part of the remaining output power to the new user through the power allocation module.

[0048] Specifically, if the new user's required charging power is 7KW at the current moment, then the original user's available power of 6.3KW and the remaining output power of 0.7KW can meet the new user's optimal charging needs.

[0049] In at least one embodiment, the control module is further configured to call the output power of at least one original user or at least one new user from a past time through the power allocation module. The method further includes: when the control module detects that a new user is enabled at the current time and at least two new users are enabled in the past time, and the callable power of each original user is respectively allocated to the new user at the corresponding past time, the control module is further configured to extract the output power of each new user from the past time to the new user at the current time through the power allocation module.

[0050] Specifically, when a new user is activated at the current moment, if there are no existing users who can allocate available power to the new user, it is necessary to extract the output power of new users from previous moments and allocate it to the new user at the current moment to ensure that the new user at the current moment can build charging behavior habit information with the best charging power.

[0051] In at least one embodiment, the control module is further configured to extract the output power of new users at each past time point to the new user at the current time point through the power allocation module, comprising: the control module being configured to acquire battery percentage data of new users at each past time point; the control module being configured to calculate the extracted power of new users at each past time point based on the battery percentage data of new users at each past time point; and the control module being further configured to allocate the extracted power of new users at each past time point to the new user at the current time point through the power allocation module, until the actual output power of the new user at the current time point is equal to the required charging power data in the charging request information.

[0052] In at least one embodiment, the power extracted by a new user at any past moment = the contribution ratio of the new user at that past moment * the charging power required by the new user at the current moment; the contribution ratio of a new user at any past moment = the battery percentage data of the new user at that past moment ÷ the sum of the battery percentage data of all new users at all past moments.

[0053] Specifically, the current charging power required by new users is 7KW. The battery percentage of new user #1 from previous times was 80%, with an output power of 7KW. The battery percentage of new user #2 from previous times was 70%, with an output power of 7KW. The battery percentage of new user #3 from previous times was 60%, with an output power of 7KW. The sum of the battery percentages of all new users from previous times is 80% + 70% + 60% = 210%. Therefore, the power extracted from new user #1 from previous times is 80 / 210 * 7KW = 2.667KW, the power extracted from new user #2 from previous times is 70 / 210 * 7KW = 2.333KW, and the power extracted from new user #3 from previous times is 60 / 210 * 7KW = 1.999KW.

[0054] In at least one embodiment, the remaining output power of the transformer = the maximum output power of the transformer - the total output power of each of the charging piles at the current moment.

[0055] Specifically, if the transformer's remaining output power is sufficient to meet the needs of a new user at the current moment, then the corresponding output power will be directly allocated to that new user.

[0056] Specifically, if the remaining output power of the transformer is insufficient to meet the needs of new users at the current moment, it is necessary to calculate and allocate the output power of the original user or new users from previous moments to the new user at the current moment, thereby ensuring that the new user at the current moment can establish complete charging habits.

[0057] Based on the same technical concept, at least one embodiment also provides a charging method as described above, comprising: a control module acquiring corresponding charging request information through each charging pile; when the control module finds charging behavior habit information matching the identity code in the charging request information in the database, the control module temporarily marks the charging pile corresponding to the charging request information as the original user; when the control module does not find charging behavior habit information matching the identity code in the charging request information in the database, and the battery percentage data in the charging request information is lower than a first percentage set threshold, the control module temporarily marks the charging pile corresponding to the charging request information as a new user; when the control module detects any new user being activated at the current moment, and the remaining output power of the transformer is not less than the required charging power data in the charging request information, the control module allocates the corresponding output power to the new user according to the required charging power data in the charging request information through the power allocation module; when the control module detects any new user being activated at the current moment, and the remaining output power of the transformer is less than the required charging power data in the charging request information, the control module calls the output power of at least one original user or at least one new user from a past moment through the power allocation module to allocate it to the new user at the current moment.

[0058] Based on the same technical concept, at least one embodiment also provides a computer-readable storage medium having computer program instructions stored thereon, which can be executed by a processor to implement the method as described above.

[0059] In summary, this invention determines that when the charging target is an existing user based on the charging request information, it charges the existing user using existing charging behavior information in the database. Simultaneously, when the charging target is determined to be a new user based on the charging request information, if the remaining output power of the transformer is not less than the charging power required by the new user, it directly allocates output power to the new user. If the remaining output power of the transformer is less than the charging power required by the new user, it ensures that the new user has sufficient charging power to build complete charging behavior information to be added to the database, while minimizing the impact on the original user's charging power. This allows for continuous optimization of the transformer allocation strategy, enabling the addition of more charging piles while maintaining the existing power supply, and ensuring optimal charging efficiency for each charging pile.

[0068] While several embodiments are provided in this disclosure, it should be understood that the disclosed systems and methods may be embodied in many other specific forms without departing from the spirit or scope of this disclosure. The present examples are intended to be illustrative rather than restrictive and are not limited to the details given. For example, various elements or components may be combined or integrated into another system, or certain features may be omitted or not implemented.

[0069] In the several embodiments provided herein, it should be understood that the disclosed apparatus and methods can also be implemented in other ways. The apparatus embodiments described above are merely illustrative; for example, the flowcharts and block diagrams in the accompanying drawings illustrate the architecture, functionality, and operation of possible implementations of apparatus, methods, and computer program products according to various embodiments of the present invention. In this regard, each block in a flowchart or block diagram may represent a module, segment, or portion of code containing one or more executable instructions for implementing a specified logical function. It should also be noted that in some alternative implementations, the functions marked in the blocks may occur in a different order than those marked in the drawings. For example, two consecutive blocks may actually be executed substantially in parallel, and they may sometimes be executed in reverse order, depending on the functions involved. It should also be noted that each block in a block diagram and / or flowchart, and combinations of blocks in block diagrams and / or flowcharts, can be implemented using a dedicated hardware-based system that performs the specified function or action, or using a combination of dedicated hardware and computer instructions.

[0070] Furthermore, without departing from the scope of this disclosure, the discrete or individual technologies, systems, subsystems, and methods described and illustrated in the various embodiments may be combined or integrated with other systems, modules, technologies, or methods.
