Description

Technical Field

[0001] The present application relates to the field of energy storage management technology, and in particular to an electric energy management method, apparatus, computer equipment, storage medium, and computer program product. Background Art

[0002] An electric vehicle is a vehicle that uses an onboard power source as its motive force and an electric motor to drive its wheels. Due to its pollution-free, low noise, and high energy efficiency, electric vehicles are gradually replacing traditional gasoline-powered electric vehicles and are widely used by users.

[0003] With the widespread use of electric vehicles, a large portion of electrical energy resources are controlled by users. Taking the electrical energy required by an electric vehicle as 100kWh as an example, 30 million electric vehicles can control a total of 3000GWh of electrical energy. How to make full use of these electrical energy resources is an urgent problem to be solved in the energy storage field. Summary of the Invention

[0004] Based on this, it is necessary to provide an electric energy management method, device, computer equipment, computer-readable storage medium and computer program product that can improve the utilization rate of electric energy resources in response to the above technical problems.

[0005] In a first aspect, the present application provides an electric energy management method, the method comprising: receiving an energy transfer request sent by an energy storage terminal device, the energy transfer request including a user identifier, an energy transfer value, and an energy transfer direction; determining a target energy account based on the user identifier; controlling the energy storage terminal device to perform an energy transfer operation when the energy transfer direction and the energy transfer value determine that the target energy account meets the energy transfer conditions; and updating the remaining energy value of the target energy account based on the energy change value monitored for the energy storage terminal device during the energy transfer process.

[0006] In the above embodiment, by creating an energy account for the user and managing the energy value in the energy account, the electric energy resources originally concentrated on the user side can be recovered into the energy storage application for energy management, so that a large amount of electric energy resources can be reasonably utilized. For example, the stored energy in the energy storage application can be transferred to the power market for peak shaving and valley filling operations, which can effectively improve the utilization rate of electric energy resources.

[0007] In some embodiments, when the energy transfer direction and the energy transfer value determine that the target energy account meets the energy transfer conditions, controlling the energy storage terminal device to perform an energy transfer operation includes: when the energy transfer direction is an extraction direction, determining the remaining energy value of the target energy account; when the remaining energy value is greater than or equal to the energy transfer value, determining that the target energy account meets the energy transfer conditions and generating an energy extraction instruction; sending the energy extraction instruction to the energy storage terminal device, and controlling the energy storage terminal device to perform the energy extraction operation based on the energy extraction instruction.

[0008] In the above embodiment, when the energy transfer direction is the extraction direction, the energy management system can quickly determine whether the target energy account meets the energy transfer conditions by comparing the remaining energy value of the target energy account with the energy transfer value. Only when the target energy account meets the energy transfer conditions will the energy storage terminal device be controlled to perform the energy extraction operation, thereby effectively improving the accuracy and efficiency of energy management.

[0009] In some embodiments, the method further includes: when the remaining energy value is less than the energy transfer value, determining that the target energy account does not meet the energy transfer condition, and generating an excess extraction prompt message; the excess extraction prompt message is used to prompt that the remaining energy value of the target energy account is insufficient; and sending the excess extraction prompt message to the energy storage terminal device.

[0010] In the above embodiment, when the remaining energy value is less than the energy transfer value, the energy management system can quickly determine that the target energy account does not meet the energy transfer conditions, thereby improving the energy management efficiency. At the same time, the energy management system can also generate corresponding excess extraction prompt information to prompt the user of the reason for the unsuccessful energy transfer, which can effectively improve the user's understanding of the energy transfer situation and thus enhance the user's usage experience.

[0011] In some embodiments, the method further includes: receiving a partial energy conversion request triggered by the extraction excess prompt information, the partial energy conversion request carrying the electric energy value to be converted; determining the equivalent resource value of the electric energy value to be converted based on the electric energy value to be converted and the regional electricity price information of the energy storage area at the current moment; calling a preset resource conversion interface according to the equivalent resource value to generate a corresponding resource conversion page; sending the resource conversion page to the energy storage terminal device; and upon receiving a resource conversion success notification returned based on the resource conversion page, controlling the energy storage terminal device to perform an energy extraction operation.

[0012] In the above embodiment, when the remaining energy value of the target energy account is insufficient, the user can use equivalent resources to exchange resources with the energy management system, and continue to transfer energy based on the exchanged energy value, which can effectively meet the user's usage needs and improve the convenience of energy transfer.

[0013] In some embodiments, when the energy transfer direction and the energy transfer value determine that the target energy account meets the energy transfer conditions, controlling the energy storage terminal device to perform an energy transfer operation includes: when the energy transfer direction is a storage direction, determining that the target energy account meets the energy transfer conditions, generating an energy storage instruction; sending the energy storage instruction to the energy storage terminal device, and controlling the energy storage terminal device to perform the energy storage operation based on the energy storage instruction.

[0014] In the above embodiment, when the energy transfer direction is the storage direction, the energy management system can directly determine whether the target energy account meets the energy transfer conditions and control the energy storage terminal device to perform energy extraction operations, effectively improving the accuracy and efficiency of energy management.

[0015] In some embodiments, the method further includes: determining the total remaining energy value of each energy account in response to an energy exchange instruction in the electricity market; determining a target exchange energy value based on the total remaining energy value and a preset guarantee ratio; and performing energy exchange in the electricity market based on the target exchange energy value.

[0016] In the above embodiment, the energy management system can determine the target exchange energy value for energy exchange in the electricity market by presetting a guaranteed ratio. When energy exchange in the electricity market is performed based on the target exchange energy value, it can not only improve the utilization rate of electric energy resources, but also maintain the stable operation of the energy storage application and improve the operational stability of the energy storage application.

[0017] In some embodiments, the method further includes: obtaining regional electricity price information at the current moment in response to an energy recharge request sent by the energy storage terminal device; generating off-peak slow charging suggestion prompt information when it is determined based on the regional electricity price information that the regional electricity price at the current moment is a off-peak electricity price; and sending the off-peak slow charging suggestion prompt information to the energy storage terminal device, where the off-peak slow charging suggestion prompt information is used to prompt whether energy recharging is required in a slow charging manner during off-peak moments.

[0018] In the above embodiment, when the energy management system determines that the regional electricity price at the current moment is a low-valley electricity price, it can generate a low-valley slow charging suggestion prompt information for the received energy recharge request, prompting the user to recharge energy through slow charging during the low-valley electricity price period, which is helpful in helping users reduce energy recharge costs and improve user convenience.

[0019] In the second aspect, the present application also provides an electric energy management device, which includes: a request receiving module for receiving an energy transfer request sent by an energy storage terminal device, the energy transfer request including a user identifier, an energy transfer value and an energy transfer direction; an account determination module for determining a target energy account based on the user identifier; an energy transfer module for controlling the energy storage terminal device to perform an energy transfer operation when the energy transfer direction and the energy transfer value determine that the target energy account meets the energy transfer conditions; an account update module for updating the remaining energy value of the target energy account based on the energy change value during the energy transfer process.

[0020] In a third aspect, the present application further provides a computer device comprising a memory and a processor, wherein the memory stores a computer program, and the processor implements the steps of the above method when executing the computer program.

[0021] In a fourth aspect, the present application further provides a computer-readable storage medium having a computer program stored thereon, which implements the steps of the above method when executed by a processor.

[0022] In a fifth aspect, the present application also provides a computer program product, comprising a computer program, which implements the steps of the above method when executed by a processor.

[0023] The above-mentioned electric energy management method, device, computer equipment, storage medium and computer program product allow users to create their own energy accounts for energy storage and extraction. When a user has an energy transfer demand, the energy management system can determine the target energy user who needs to transfer energy based on the user identifier carried in the received energy transfer request. When it is determined that the target energy account meets the energy transfer conditions, the energy management system can control the energy storage terminal device to perform the energy transfer operation, and at the same time monitor the energy change value of the energy storage terminal device in real time to update the remaining energy value of the target energy account. By creating a user's own energy account and managing the energy value in the energy account, the electric energy resources originally concentrated on the user side can be recycled into the energy storage application for energy management, so that a large amount of electric energy resources can be reasonably utilized. For example, the stored energy in the energy storage application can be transferred to the power market for peak shaving and valley filling operations, which can effectively improve the utilization rate of electric energy resources.

[0038] The following embodiments of the technical solution of the present application will be described in detail with reference to the accompanying drawings. The following embodiments are only used to more clearly illustrate the technical solution of the present application and are therefore only examples and are not intended to limit the scope of protection of the present application.

[0039] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those skilled in the art to which this application belongs; the terms used herein are only for the purpose of describing specific embodiments and are not intended to limit this application; the terms "including" and "having" and any variations thereof in the specification and claims of this application and the above-mentioned figure descriptions are intended to cover non-exclusive inclusions.

[0040] References herein to "embodiments" mean that a particular feature, structure, or characteristic described in connection with the embodiments may be included in at least some embodiments of the present application. The appearance of this phrase in various places in the specification does not necessarily refer to the same embodiment, nor does it constitute an independent or alternative embodiment that is mutually exclusive of other embodiments. It is understood, both explicitly and implicitly, by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0041] In the description of the embodiments of the present application, the term "multiple" refers to more than two (including two). Similarly, "multiple groups" refers to more than two groups (including two groups), and "multiple pieces" refers to more than two pieces (including two pieces).

[0042] In the description of the embodiments of the present application, the technical terms "center", "longitudinal", "lateral", "length", "width", "thickness", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", "clockwise", "counterclockwise", "axial", "radial", "circumferential", etc., indicating the orientation or position relationship, are based on the orientation or position relationship shown in the accompanying drawings, and are only for the convenience of describing the embodiments of the present application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the embodiments of the present application.

[0043] In the description of the embodiments of the present application, unless otherwise expressly specified or limited, technical terms such as "installed," "connected," "connected," and "fixed" should be understood in a broad sense. For example, they can refer to fixed connections, detachable connections, or integration; mechanical connections or electrical connections; direct connections or indirect connections through an intermediate medium; internal connections between two components or interactions between two components. Those skilled in the art can understand the specific meanings of the above terms in the embodiments of the present application based on specific circumstances.

[0044] With the extensive use of electric vehicles and other power tools, a large portion of electric energy resources are controlled by users and stored in a centralized and fixed manner in mobile energy storage devices, such as the onboard power supply of electric vehicles for the operation of electric vehicles. Even when the electric vehicles are out of use, the electric energy resources cannot be released from the mobile energy storage devices for effective and reasonable utilization, which leads to a low utilization rate of a large portion of electric energy resources.

[0045] In order to improve the utilization rate of electric energy resources, energy storage application companies or institutions can create their own energy accounts for users for energy storage and extraction. When a user has an energy transfer demand, the energy management system can determine the target energy user to whom energy transfer is required based on the user identifier carried in the received energy transfer request. When it is determined that the target energy account meets the energy transfer conditions, the energy management system can control the energy storage terminal device to perform the energy transfer operation, while monitoring the energy change value of the energy storage terminal device in real time and updating the remaining energy value of the target energy account. By creating a user's own energy account and managing the energy value in the energy account, the electric energy resources originally centralized on the user side can be recycled into the energy storage application for energy management, so that a large amount of electric energy resources can be reasonably utilized. For example, the stored energy in the energy storage application can be transferred to the power market for peak shaving and valley filling operations, which can effectively improve the utilization rate of electric energy resources.

[0046] The electric energy management method provided in the embodiment of the present application can be applied to Figure 1 In the application environment shown. Among them, energy storage application enterprises or institutions can set up corresponding energy storage areas in various places according to the actual energy storage layout. Each energy storage area will be equipped with an energy storage terminal device 102. The energy storage terminal device 102 is a physical hardware device for energy transfer and storage, which can exchange or transfer energy with the user side to achieve the effect of energy storage and energy sharing applications. It can be understood that the actual application business of the energy storage application is different, and the energy storage terminal device 102 set in the energy storage area will also be different. For example, in the electric vehicle energy storage application scenario, the energy storage terminal device 102 set in the energy storage area can be an electric vehicle charging device, including a bidirectional charging component and a corresponding charging gun. The number of energy storage terminal devices 102 set in each energy storage area can also be determined according to the actual energy storage application requirements and the actual creation environment of the energy storage area.

[0047] The energy management system 104 can communicate with the energy storage terminal devices 102 in each energy storage area through wireless communication, and the data storage system can store data that the energy management system 104 needs to process. The data storage system can be integrated into the energy management system 104, or it can be placed on the cloud or other network servers. When a user has a need for energy transfer, the user can generate an energy transfer request including a user identifier, an energy transfer value, and an energy transfer direction based on the energy storage terminal device 102 in the energy storage area where the user is located, and send the energy transfer request to the energy management system 104 through the energy storage terminal device 102. After receiving the energy transfer request sent by the energy storage terminal device 102, the energy management system 104 determines the target energy account corresponding to the user identifier based on the user indication carried in the request. If the energy transfer direction and energy transfer value determine that the target energy account meets the energy transfer conditions, the energy management system 104 controls the energy storage terminal device 102 to perform the energy transfer operation and updates the remaining energy value of the target energy account based on the energy change value during the energy transfer process.

[0048] The energy management system 104 can be compared to an energy bank's management system, managing energy storage information in energy accounts and controlling energy transfers to the energy storage terminal devices 102. The energy management system 104 can be implemented using a standalone server or a server cluster consisting of multiple servers, or it can provide management services through cloud services.

[0049] In some embodiments, the energy management system 104 may be composed of a cloud service module and a monitoring platform module. The monitoring platform module is used to monitor the energy change value of the energy storage terminal device 102 in real time, and send the monitored information to the cloud service in the energy management system 104. The cloud service manages the energy value stored in the energy account based on the energy change value.

[0050] In some embodiments, as Figure 2 As shown, a method for managing electric energy is provided. Figure 1 The energy management system 104 in FIG. 1 is used as an example to illustrate the process, which includes the following steps:

[0051] S202: Receive an energy transfer request sent by an energy storage terminal device, where the energy transfer request includes a user identifier, an energy transfer value, and an energy transfer direction.

[0052] Among them, energy transfer refers to the process of transferring electric energy resources. The energy transfer process does not involve the transformation of energy resources, that is, the nature of electric energy resources will not change during the energy transfer process. What changes is only the storage location of the electric energy resources.

[0053] An energy transfer request is a request generated by an energy storage terminal device when a user has an energy transfer demand. The energy transfer request carries a user identifier, an energy transfer value, and an energy transfer direction.

[0054] The user identifier is used to distinguish different users. The user identifier can include a user name, an ID (Identity document, a unique number), or any other characters that can be used to represent, such as numbers, letters, and feature codes, as long as different users can be distinguished.

[0055] The energy transfer value is the specific electric energy value to be transferred according to the user's own needs. The energy transfer value can be a random value entered by the user, or a value provided by the device selected by the user through a click operation on the energy storage terminal device.

[0056] The energy transfer direction is a directional parameter used to characterize the direction in which electric energy resources flow during energy transfer operations. The energy transfer direction can include an extraction direction and a storage direction. The extraction direction refers to the corresponding transfer direction when transferring electric energy resources from the energy storage terminal device to the user's terminal. When the user selects the extraction direction, it means that the electric energy resources will flow from the energy storage terminal device to the user's terminal. The storage direction refers to the corresponding transfer direction when transferring electric energy resources from the user's terminal to the energy storage terminal device. When the user selects the storage direction, it means that the electric energy resources will flow from the user's terminal to the energy storage terminal device.

[0057] In some embodiments, the energy management system receives an energy transfer request sent by the energy storage terminal device, and obtains the user identifier, energy transfer value, and energy transfer direction carried in the energy transfer request.

[0058] In some embodiments, when a user requests energy transfer, they can log in to the energy storage terminal device. In response to the user's login, the energy storage terminal device obtains a user ID and generates an energy transfer interface for display. In response to the user selecting an energy transfer direction based on the energy transfer interface and determining an energy transfer value for the energy transfer, the energy storage terminal device generates an energy transfer request and sends it to the energy management system.

[0059] S204: Determine a target energy account according to the user identifier.

[0060] An energy account refers to an account opened by an energy storage application organization or enterprise for a user in an energy management system, used to record the account's energy storage information. An energy account can be compared to a bank account, and the energy management system can be compared to a bank management system. Users can store excess energy in or extract required energy from energy storage devices managed by the energy management system when they wish to transfer energy. The energy management system also records energy transfer information in the energy account during the energy transfer process.

[0061] In some embodiments, the energy management system searches for an energy account corresponding to the user identifier in the account set managed by the energy management system based on the user identifier obtained from the energy transfer request, and determines the energy account corresponding to the user identifier as the target energy account.

[0062] In some embodiments, the energy management system pre-sets a correspondence between each energy account and the user identifier. After obtaining the user identifier from the energy transfer request, the energy management system can call the pre-set correspondence, search for the energy account corresponding to the user identifier, and determine the energy account corresponding to the user identifier as the target energy account.

[0063] S206 , when the energy transfer direction and the energy transfer value determine that the target energy account meets the energy transfer conditions, controlling the energy storage terminal device to perform an energy transfer operation.

[0064] The energy transfer condition is a pre-set condition used to determine whether the energy value stored in the target energy account can meet the user's energy transfer needs. If the target energy account meets the energy transfer condition, it can be considered that the energy value stored in the target energy account can meet the user's energy transfer needs. It can be understood that the energy transfer condition is related to the energy transfer direction selected by the user.

[0065] In some embodiments, the energy management system can determine the energy transfer conditions corresponding to the target energy account during this energy transfer process based on the acquired energy transfer direction, and determine whether the target energy account meets the energy transfer conditions based on the energy transfer value. If the target energy account meets the energy transfer conditions, the energy management system can control the energy storage terminal device to perform the energy transfer operation.

[0066] In some embodiments, the energy management system may generate corresponding energy transfer execution instructions based on the energy transfer direction and energy transfer value, send the energy transfer execution instructions to the energy storage terminal device, and control the energy storage terminal device to perform energy transfer operations based on the energy transfer execution instructions.

[0067] S208: Update the remaining energy value of the target energy account according to the energy change value during the energy transfer process.

[0068] The energy change value is the change value of the energy stored in the energy storage terminal device itself during the energy transfer process. It can be understood that the energy change value can represent the actual energy value transferred during the energy transfer process.

[0069] In some embodiments, during the energy transfer process, the energy management system can monitor energy changes in the energy storage terminal device performing the energy transfer operation, determine the energy change value of the energy storage terminal device during the energy transfer process in real time, and update the energy value information stored in the target energy account based on the monitored energy change value to obtain the remaining energy value of the target energy account. Updating the remaining energy value of the target energy account by implementing the monitored energy change value, rather than directly updating the remaining energy value in the target energy account based on the energy transfer value, can effectively improve the accuracy of updating the remaining energy value in the target energy account.

[0070] In some embodiments, the energy management system can monitor the energy change value of the energy storage terminal device in real time based on the configured monitoring platform.

[0071] In some embodiments, when performing an energy transfer operation, the energy storage terminal device can send the energy change during the energy transfer process in the form of a signal to the monitoring platform of the energy management system. The monitoring platform can monitor the energy change value of the energy storage terminal device in real time based on the received signal.

[0072] In the above-mentioned electric energy management method, users can create their own energy accounts for energy storage and extraction. When a user has an energy transfer demand, the energy management system can determine the target energy user who needs to transfer energy based on the user identifier carried in the received energy transfer request. When it is determined that the target energy account meets the energy transfer conditions, the energy management system can control the energy storage terminal device to perform the energy transfer operation, and at the same time monitor the energy change value of the energy storage terminal device in real time to update the remaining energy value of the target energy account. By creating a user's own energy account and managing the energy value in the energy account, the electric energy resources originally concentrated on the user side can be recycled into the energy storage application for energy management, so that a large amount of electric energy resources can be reasonably utilized. For example, the stored energy in the energy storage application can be transferred to the power market for peak shaving and valley filling operations, which can effectively improve the utilization rate of electric energy resources.

[0073] Since the energy transfer condition is related to the energy transfer direction selected by the user, several embodiments will be used below to illustrate how to determine whether the target energy account meets the energy transfer condition.

[0074] In some embodiments, as Figure 3 As shown, in S206, when the energy transfer direction and the energy transfer value determine that the target energy account meets the energy transfer conditions, controlling the energy storage terminal device to perform the energy transfer operation includes:

[0075] S302: When the energy transfer direction is an extraction direction, determine the remaining energy value of the target energy account.

[0076] Among them, the extraction direction refers to the corresponding transfer direction when transferring electric energy resources from the energy storage terminal device to the user's terminal. When the energy transfer direction selected by the user is the extraction direction, it means that the electric energy resources will flow from the energy storage terminal device to the user's terminal.

[0077] In some embodiments, when the energy management system determines that the energy transfer direction indicated in the energy transfer request is an extraction direction, it indicates that the user needs to extract energy pre-stored in the energy account, and the electric energy resource will be transferred from the energy storage terminal device to the user's user terminal. Because this involves the transfer of electric energy resources, the energy management system must first determine whether the user has sufficient energy stored in the energy account to meet the current extraction requirement. Therefore, the energy management system needs to determine the remaining energy value stored in the target energy account corresponding to the user identifier before the energy transfer occurs.

[0078] S304: When the remaining energy value is greater than or equal to the energy transfer value, determine that the target energy account meets the energy transfer condition and generate an energy extraction instruction.

[0079] The energy extraction instruction is a command signal used to instruct the energy storage terminal device to transfer internally stored electrical energy to the user's terminal. The energy extraction instruction can be generated by the energy management system based on the energy transfer value and energy transfer direction and sent to the energy storage terminal device.

[0080] In some embodiments, the energy management system may compare the remaining energy value of the target energy account before the energy transfer operation is performed with the energy transfer value specified by the user in the energy transfer request. If the remaining energy value is greater than or equal to the energy transfer value, it indicates that the target energy account has sufficient remaining energy to meet the energy transfer requirements, and the target energy account is determined to meet the energy transfer conditions. The energy management system may generate an energy extraction instruction based on the energy transfer value and the energy transfer direction.

[0081] S306: Send the energy extraction instruction to the energy storage terminal device, and control the energy storage terminal device to perform an energy extraction operation based on the energy extraction instruction.

[0082] Among them, the energy extraction operation refers to the processing process of the energy storage terminal device transferring the electric energy resources stored inside the device to the user's terminal.

[0083] In some embodiments, the energy management system generates an energy extraction instruction based on the energy transfer value and the energy transfer direction, and can send the energy extraction instruction to the energy storage terminal device, and control the energy storage terminal device based on the energy extraction instruction to transfer electrical energy from the energy storage terminal device to the user's terminal.

[0084] In the above embodiment, when the energy transfer direction is the extraction direction, the energy management system can quickly determine whether the target energy account meets the energy transfer conditions by comparing the remaining energy value of the target energy account with the energy transfer value. Only when the target energy account meets the energy transfer conditions will the energy storage terminal device be controlled to perform the energy extraction operation, thereby effectively improving the accuracy and efficiency of energy management.

[0085] In other embodiments, Figure 4 As shown, the electric energy management method further includes the following steps:

[0086] S402: When the remaining energy value is less than the energy transfer value, it is determined that the target energy account does not meet the energy transfer conditions, and an excess withdrawal prompt message is generated.

[0087] The extraction excess prompt information is prompt information used to prompt that the remaining energy value of the target energy account is insufficient.

[0088] In some embodiments, the energy management system compares the remaining energy value of the target energy account before the energy transfer operation is performed with the energy transfer value specified by the user in the energy transfer request. If the remaining energy value is determined to be less than the energy transfer value, it indicates that the electric energy stored in the target energy account cannot meet the energy transfer requirements, and the target energy account can be determined to be ineligible for energy transfer. The energy management system can generate an over-withdrawal prompt message.

[0089] In some embodiments, the excess energy withdrawal prompt information may be generated by the energy management system based on the energy difference between the energy transfer value and the remaining energy value. If the energy management system determines that the target energy account does not meet the energy transfer conditions, it may calculate the energy difference between the energy transfer value and the remaining energy value and generate the excess energy withdrawal prompt information based on the energy difference. The excess energy withdrawal prompt information may not only inform the user that the remaining energy value in the target energy account is insufficient, but may also inform the user of the energy difference between the current remaining energy value in the target energy account and the energy transfer value required by the user.

[0090] S404: Send the excess extraction prompt information to the energy storage terminal device.

[0091] In some embodiments, after generating the excess withdrawal prompt information, the energy management system sends the excess withdrawal prompt information to the energy storage terminal device for display. The user can determine the reason for the failure of the energy transfer request based on the excess withdrawal prompt information displayed by the energy storage terminal device.

[0092] In the above embodiment, when the remaining energy value is less than the energy transfer value, the energy management system can quickly determine that the target energy account does not meet the energy transfer conditions, thereby improving the energy management efficiency. At the same time, the energy management system can also generate corresponding excess extraction prompt information to prompt the user of the reason for the unsuccessful energy transfer, which can effectively improve the user's understanding of the energy transfer situation and thus enhance the user's usage experience.

[0093] Furthermore, in order to satisfy the energy transfer requirements of the user, in some embodiments, Figure 5 As shown, the electric energy management method further includes the following steps:

[0094] S502: Receive a partial energy conversion request triggered by the extraction of excess prompt information, where the partial energy conversion request carries the value of electric energy to be converted.

[0095] Energy conversion refers to a resource conversion operation that uses other resources of equal value to the amount of electrical energy to be converted to exchange for electrical energy resources from the energy management system. A partial energy conversion request is generated when a user still wants to obtain energy from an energy storage terminal device after receiving an over-capacity notification. The partial energy conversion request carries the user-specified amount of electrical energy to be converted.

[0096] In some embodiments, after the energy storage terminal device displays an over-extraction prompt, the user can choose to continue the extraction operation based on the over-extraction prompt. Based on the energy difference information contained in the over-extraction prompt or the remaining energy value in the target energy account, the user can enter the corresponding energy value to be converted on the energy storage terminal device, thereby triggering the generation of a partial energy conversion request. The energy storage terminal device then sends the partial energy conversion request to the energy management system.

[0097] In some embodiments, when the energy management system receives a partial energy conversion request triggered by the user based on the extraction of excess prompt information, it indicates that the user still has energy conversion needs, and the energy management system obtains the electric energy value to be converted carried by the request from the partial energy conversion request.

[0098] S504 : Determine the equivalent resource value of the electric energy value to be converted based on the electric energy value to be converted and the regional electricity price information of the energy storage area at the current moment.

[0099] Among them, the electricity price information of the energy storage area at the current moment is used to represent the equivalent resource conversion information of the electric energy resources in the energy storage area at the current moment. Since the electricity price mechanism used in the current power system is a time-of-use electricity price mechanism, the electricity price information corresponding to the same energy storage area may be different at different times. By obtaining the regional electricity price information of the energy storage area at the current moment, it is possible to determine the equivalent resource value that needs to be provided in the energy storage area to obtain the electric energy value to be converted at the current moment.

[0100] In some embodiments, the energy management system pre-stores grid information data of each energy storage area under management. The grid information data may include regional electricity price data of the corresponding energy storage area at various times. The energy management system only needs to determine the regional electricity price information of the energy storage area at the current moment based on the regional electricity price data of the energy storage area.

[0101] In some embodiments, the energy management system is also in communication with a regional power grid server, and can obtain regional electricity price information of the energy storage area at the current moment from the regional power grid server in real time.

[0102] In some embodiments, the energy management system obtains regional electricity price information for the energy storage area at the current moment, and determines an equivalent resource value for the energy value to be converted based on the regional electricity price information for the energy storage area at the current moment and the energy value to be converted carried in the partial energy conversion request. It is understood that the regional electricity price information can be used to represent the basic equivalent resource value corresponding to the basic electric energy value. The energy management system can use the basic equivalent resource value to obtain the equivalent resource value corresponding to the energy value to be converted based on the proportional relationship between the energy value to be converted and the basic electric energy value.

[0103] S506: Calling a preset resource conversion interface according to the equivalent resource value to generate a corresponding resource conversion page.

[0104] Among them, since the energy conversion process involves the conversion of electric energy resources and other equivalent resources, that is, the energy conversion process involves the transformation of energy resources, in order to improve the security of the resource conversion process, the energy management system will pre-set a resource conversion interface with the third-party resource provider platform corresponding to the equivalent resources used for conversion, that is, a preset resource conversion interface. The preset resource conversion interface is configured with a conversion agreement determined after negotiation between the two parties. When resource conversion is required, the energy management system generates a resource conversion page and displays it to the user by calling the preset resource transfer interface. Based on the resource conversion page, the user can extract the corresponding equivalent resources from the third-party resource provider platform and perform energy conversion with the energy management system.

[0105] In some embodiments, after determining the equivalent resource value corresponding to the electric energy value to be converted, the energy management system may call a preset resource transfer interface configured after negotiation with a third-party resource providing platform to generate a corresponding resource conversion page.

[0106] S508: Send the resource conversion page to the energy storage terminal device.

[0107] In some embodiments, after generating the resource conversion page, the energy management system sends the resource conversion page to the energy storage terminal device, and displays the page to the user based on the energy storage terminal device.

[0108] S510 , upon receiving a notification of successful resource conversion returned based on the resource conversion page, controlling the energy storage terminal device to perform an energy extraction operation.

[0109] The resource conversion success notification is a notification message generated when the user successfully transfers equivalent resources from a third-party resource provider platform to the energy management system based on the resource conversion page. Upon receiving the resource conversion success notification, the user has completed the transfer of the equivalent resource value and can control the energy storage terminal device to provide the corresponding electric energy resources to the user. It is understood that the resource conversion success notification can be generated and sent by the third-party resource provider platform, or generated by the resource receiving module in the energy management system.

[0110] In some embodiments, upon receiving a notification of successful resource conversion returned based on the conversion page, the energy management system may control the energy storage terminal device to perform an energy extraction operation based on the electric energy value to be converted and the energy transfer value.

[0111] In some of these embodiments, the energy management system can determine the total energy extraction value based on the electric energy value to be converted and the energy transfer value, generate an energy extraction instruction based on the total energy extraction value, and send the energy extraction instruction to the energy storage terminal device. The energy extraction instruction controls the energy storage terminal device to transfer the electric energy resource value equal to the total energy extraction value from the internal storage of the device to the user's terminal.

[0112] In the above embodiment, when the remaining energy value of the target energy account is insufficient, the user can use equivalent resources to exchange resources with the energy management system, and continue to transfer energy based on the exchanged energy value, which can effectively meet the user's usage needs and improve the convenience of energy transfer.

[0113] In other embodiments, based on the extracted overage prompt information, the user can modify the energy transfer value on the energy storage terminal device and re-trigger the generation of an energy transfer request based on the modified energy transfer value. The energy management system controls the energy storage terminal device to perform the energy transfer operation based on the newly generated energy transfer request.

[0114] In addition to the energy transfer direction, the energy transfer direction can also be the storage direction. In some embodiments, S206, when the energy transfer direction and the energy transfer value determine that the target energy account meets the energy transfer conditions, controlling the energy storage terminal device to perform the energy transfer operation includes:

[0115] If the energy transfer direction is a storage direction, it is determined that the target energy account meets the energy transfer conditions, an energy storage instruction is generated, the energy storage instruction is sent to the energy storage terminal device, and the energy storage terminal device is controlled to perform an energy storage operation based on the energy storage instruction.

[0116] The storage direction refers to the direction in which electric energy resources are transferred from the user's terminal to the energy storage terminal device. When the user selects the storage direction, the electric energy resources flow from the user's terminal to the energy storage terminal device. The energy storage operation refers to the process by which the energy storage terminal device transfers the electric energy resources stored in the user's terminal to the energy storage terminal device for internal storage.

[0117] An energy storage instruction is a signal that instructs an energy storage terminal device to transfer the electrical energy stored in the user's terminal to the terminal device for internal storage. The energy storage instruction can be generated by the energy management system based on the energy transfer value and the energy transfer direction (i.e., the storage direction) and sent to the energy storage terminal device.

[0118] In some embodiments, when the energy management system determines that the energy transfer direction indicated in the energy transfer request is a storage direction, it indicates that the user needs to transfer the energy stored in the user terminal to the energy storage terminal device for storage, and the electric energy resource will be transferred from the user terminal to the energy storage terminal device. Because the energy storage process does not involve the transfer of electric energy resources, the energy management system does not need to determine whether the target energy account has sufficient energy value stored and can directly determine that the target energy account meets the energy transfer conditions.

[0119] The energy management system can generate energy storage instructions based on the energy transfer value and energy transfer direction, and send the energy storage instructions to the energy storage terminal device. Based on the energy storage instructions, the energy storage terminal device is controlled to perform energy storage operations, and the electric energy resources stored in the user terminal are transferred to the energy storage terminal device for storage.

[0120] In the above embodiment, when the energy transfer direction is the storage direction, the energy management system can directly determine whether the target energy account meets the energy transfer conditions and control the energy storage terminal device to perform energy extraction operations, effectively improving the accuracy and efficiency of energy management.

[0121] In other embodiments, when the energy management system determines that the energy transfer direction is a storage direction, it can determine the account level of the target energy account and, based on the account level, determine whether the target energy account has a single energy storage time limit or a total energy storage limit. If it is determined that the target energy account does not have an energy storage limit, the energy management system can directly determine that the target energy account meets the energy transfer conditions. If it is determined that the target energy account has an energy storage limit, the energy management system needs to determine whether the target energy account meets the energy transfer conditions based on the energy transfer value and / or the remaining energy value in the target energy account.

[0122] When the energy management system manages the electric energy resources, in order to improve the utilization rate of the electric energy resources, in some embodiments, Figure 6 As shown, the electric energy management method further includes the following steps:

[0123] S602 : In response to the energy exchange instruction of the electricity market, determine the total remaining energy value of each energy account.

[0124] The power market energy exchangeable instruction is a signal indicating that energy exchange is currently possible in the power market. Since the current power system implements a time-of-use pricing mechanism, the energy management system can take advantage of the price fluctuations corresponding to peak and valley periods in the power market and use electric energy resources to participate in resource exchange, effectively improving the utilization rate of electric energy resources.

[0125] In some embodiments, the power market energy exchange instruction may be a command signal triggered when electricity prices in the power market are at a low point or when electricity prices in the power market are at a peak point. In other embodiments, the power market energy exchange instruction may also be a command signal triggered when the power market meets the conditions for cross-regional energy storage.

[0126] In some embodiments, the electricity market energy exchangeable instruction may also be triggered and generated by an energy management personnel based on grid information.

[0127] In some embodiments, the total remaining energy value is the total value of the remaining energy values ​​stored in all energy accounts managed by the energy management system, and can be calculated by the energy management system based on the sum of the remaining energy values ​​of each energy account.

[0128] In some of these embodiments, due to actual usage factors or the influence of the actual energy storage performance of each energy storage device in the energy storage area, the energy value that the energy management system can allocate may be less than the total value of the remaining energy values ​​stored in all energy accounts managed by the energy management system. Therefore, when the energy value that the energy management system can allocate is less than the total value of the remaining energy values ​​stored in all energy accounts, the energy value that the energy management system can allocate is determined as the total remaining energy value.

[0129] In some of these embodiments, due to the actual energy storage layout of the energy storage application enterprise or organization, the energy value that the energy management system can allocate may be greater than the total value of the remaining energy values ​​stored in all energy accounts managed by the energy management system. In this case, the energy value that the energy management system can allocate can be determined as the total remaining energy value.

[0130] In some embodiments, the total remaining energy value is the sum of the remaining energy values ​​stored in energy accounts in a stable state in the energy management system. In response to the energy exchangeable instruction from the electricity market, the energy management system can determine the energy accounts currently in a stable state and sum the remaining energy values ​​of the energy accounts in the stable state to obtain the total remaining energy value. It will be appreciated that a stable energy account refers to an energy account in which no energy transfer operation has occurred at the current moment.

[0131] In some embodiments, the energy management system determines a total remaining energy value of each energy account based on each energy account managed in response to the electricity market energy exchangeable instruction.

[0132] S604: Determine a target exchange energy value according to the total remaining energy value and a preset guarantee ratio.

[0133] Among them, the preset guarantee ratio is a proportional coefficient set to maintain the stable operation of the energy storage application. When performing energy exchange operations with the power market, in order to maintain the stable operation of the energy storage application, the energy management system cannot use all the electric energy resources stored in the energy storage area to participate in the energy exchange of the power market, but needs to reserve a part to meet the energy transfer or energy exchange operations with the user side. Therefore, by presetting the guarantee ratio, the energy management system can withhold a part of the electric energy resources from the total remaining energy value as reserved resources. Analogous to the bank's margin, the reserved resources can also be regarded as energy margin. It can be understood that the preset guarantee ratio can be determined by the energy management personnel based on the actual application of the energy storage application. For example, the preset guarantee ratio can be determined based on the historical application rate of the energy storage application in different time periods to improve the stability of the operation of the energy storage application.

[0134] In some embodiments, after determining the total remaining energy value, the energy management system may determine an energy guarantee value based on a preset guarantee ratio from the total remaining energy value to maintain stable operation of the energy storage application, and then determine the difference between the total remaining energy value and the energy guarantee value as the target exchange energy value. It will be understood that the target exchange energy value is the value of electric energy resources that can be invested in the power market for energy exchange.

[0135] S606: Performing energy exchange in the electricity market based on the target exchange energy value.

[0136] In some embodiments, after determining the target exchange energy value, the energy management system may input the target exchange energy value into the electricity market for energy exchange to improve the utilization rate of electric energy resources.

[0137] In the above embodiment, the energy management system can determine the target exchange energy value for energy exchange in the electricity market by presetting a guaranteed ratio. When energy exchange in the electricity market is performed based on the target exchange energy value, it can not only improve the utilization rate of electric energy resources, but also maintain the stable operation of the energy storage application and improve the operational stability of the energy storage application.

[0138] From the user's perspective, in some embodiments, such as Figure 7 As shown, the electric energy management method further includes the following steps:

[0139] S702 , in response to the energy recharge request sent by the energy storage terminal device, obtain regional electricity price information at the current moment.

[0140] An energy recharge request is a request message generated by an energy storage terminal device when a user has a need for energy recharge. The energy recharge process can be considered the process of the user acquiring electrical energy resources from the energy storage terminal device entirely through resource exchange. The energy recharge request can include the energy value to be charged, the energy storage terminal device identifier, and the energy recharge request time. The energy value to be charged is the specific amount of electrical energy that the user determines to be converted based on their needs. Similarly, the energy value to be charged can be a random value entered by the user or a value provided by the device selected by the user through a click on the energy storage terminal device. The energy storage terminal device identifier is unique identification information used to distinguish different energy storage terminal devices. The energy storage terminal device identifier can be any character that can be used to represent different energy storage terminal devices, such as numbers, letters, or feature codes, as long as it can distinguish different energy storage terminal devices. The energy recharge request time refers to the time when the user triggers the energy recharge request based on the energy storage terminal device. The energy management system can obtain regional electricity price information based on the energy recharge request time to facilitate understanding of the regional electricity price in the energy storage area at the current moment.

[0141] In some embodiments, when a user needs to recharge energy, the energy storage terminal device can trigger the generation of an energy recharge request containing the amount of energy to be charged and the identifier of the energy storage terminal device, and send the request to the energy management system. The energy management system receives the energy recharge request from the energy storage terminal device and obtains the amount of energy to be charged, the identifier of the energy storage terminal device, and the time of the energy recharge request based on the energy recharge request.

[0142] S704: When it is determined based on the regional electricity price information that the current regional electricity price is a low-peak electricity price, generate low-peak slow charging suggestion prompt information.

[0143] The off-peak slow charging suggestion prompt information is used to prompt the user whether it is necessary to recharge energy in a slow charging manner during off-peak hours.

[0144] In some embodiments, in order to improve the efficiency of energy transfer by users, save energy transfer time, and thus increase users' willingness to store energy, when performing energy transfer operations, users can directly use the fast charging or supercharging function of the energy storage terminal device to perform fast energy transfer. Taking energy transfer as an example of charging operation, when using the fast charging function for energy transfer, the charging power of the energy storage terminal device can reach 200kW~500kW, and the charging time is ≤15min. It is understandable that energy storage terminal devices with fast charging or supercharging functions will also have slow charging functions.

[0145] The energy recharge process is different from the energy transfer process. Users do not extract pre-stored energy, but need to use certain equivalent resources to exchange resources with the energy management system to obtain corresponding energy resources. Therefore, if the regional electricity price is at a low point at the current moment, users use the slow charging function to recharge energy. Compared with using fast charging for energy recharge, the required recharge cost is lower.

[0146] In some embodiments, after receiving an energy recharge request, the energy management system can obtain the regional electricity price information of the energy storage area at the current moment. When it is determined that the regional electricity price of the energy storage area is a valley electricity price based on the regional electricity price information at the current moment, it can generate valley slow charging suggestion prompt information based on the energy storage terminal device identifier to prompt the user whether it is necessary to recharge energy in a slow charging manner at valley moments to reduce the energy recharge cost.

[0147] S706: Send the low-peak slow charging suggestion prompt information to the energy storage terminal device for display.

[0148] In some embodiments, the energy management system sends the generated off-peak slow charging suggestion prompt information to the energy storage terminal device for display. Based on the off-peak slow charging suggestion prompt information displayed by the energy storage terminal device, the user can determine whether to use the slow charging function of the energy storage terminal device to recharge energy according to their own recharging needs.

[0149] In the above embodiment, when the energy management system determines that the regional electricity price at the current moment is a low-valley electricity price, it can generate a low-valley slow charging suggestion prompt information for the received energy recharge request, prompting the user to recharge energy through slow charging during the low-valley electricity price period, which is helpful in helping users reduce energy recharge costs and improve user convenience.

[0150] In some embodiments, an electric energy management method is provided, which is illustrated by taking the application of the method to an energy bank in an electric vehicle energy storage application scenario as an example.

[0151] like Figure 8 As shown, the energy bank includes cloud services, a monitoring platform and energy storage terminal equipment. The energy storage terminal equipment includes a fast charging / super charging charging device and an energy storage device. The energy storage terminal equipment communicates with the cloud service and monitoring platform via wireless 4G / 5G communication. The energy storage terminal equipment can realize the fast charging / super charging function of electric vehicles. The charging power of the charging device is 200kW~500kW, and the charging time is ≤15min.

[0152] The specific power energy management methods include: Figure 9 The energy transfer process shown in Figure 10 The energy exchange process shown in FIG. The energy transfer process includes the following steps:

[0153] S901: Receive an energy transfer request sent by an energy storage terminal device, where the energy transfer request includes a user identifier, an energy transfer value, and an energy transfer direction.

[0154] In some embodiments, there are two transfer situations for energy transfer. For example, when a user is willing to store electric energy, he or she can log in to the energy storage terminal device, select the "electricity storage mode" based on the charging device of the energy storage terminal device, and determine the energy storage value when storing electric energy according to his or her own electricity usage habits. After clicking OK, it triggers the generation of an energy storage request, which includes a user identifier, an energy storage value, and a storage direction.

[0155] For example, when a user is willing to retrieve electric energy from an energy bank, he or she can log in to the energy storage terminal device, select the "electric energy retrieval mode" based on the charging device of the energy storage terminal device, determine the energy retrieval value when retrieving electric energy according to his or her own electricity usage habits, and click OK to trigger the generation of an energy retrieval request. The energy retrieval request includes user identification, energy retrieval value and extraction direction.

[0156] The energy storage terminal device sends an energy transfer request to the cloud service, and the cloud service obtains the user identifier, energy transfer value, and energy transfer direction carried in the energy transfer request.

[0157] S902: Determine a target energy account corresponding to the user identifier according to the user identifier.

[0158] S903: When it is determined that the energy transfer direction is the storage direction, execute S904; when it is determined that the energy transfer direction is the extraction direction, execute S905.

[0159] S904: Generate an energy storage instruction according to the energy transfer value and the storage direction, and control the energy storage terminal device to perform an energy storage operation based on the energy storage instruction.

[0160] In some embodiments, the electrical energy resources of the energy storage operation flow to Figure 11 As shown, the cloud service generates an energy storage instruction based on the energy transfer value and storage direction, and sends the energy storage instruction to the energy storage terminal device. The energy storage terminal device responds to the energy storage instruction and transfers the electric energy resources of the user's electric vehicle to the energy storage device for storage through the charging gun equipped with the charging device.

[0161] S905: Obtain the remaining energy value of the target energy account.

[0162] S906: When the remaining energy value is greater than or equal to the energy transfer value, an energy extraction instruction is generated according to the energy transfer value and the extraction direction, and the energy storage terminal device is controlled to perform an energy extraction operation based on the energy storage instruction.

[0163] In some embodiments, the electrical energy resources of the energy extraction operation flow to Figure 12 As shown, the cloud service generates an energy extraction instruction based on the energy transfer value and extraction direction, and sends the energy extraction instruction to the energy storage terminal device. The energy storage terminal device responds to the energy extraction instruction and transfers the electric energy resources stored in the energy storage device to the user's electric vehicle for storage through the charging gun equipped with the charging device.

[0164] S907: When the remaining energy value is less than the energy transfer value, an excess energy prompt message is generated and displayed.

[0165] S908 , updating the remaining energy value of the target energy account according to the energy change value monitored during the energy transfer process.

[0166] In some embodiments, the energy bank monitors the energy change value of the energy storage terminal device during the energy transfer process in real time through a monitoring platform, and feeds back the energy change value to the cloud service. The cloud service updates the remaining energy value of the target energy account based on the energy change value obtained through monitoring.

[0167] The energy exchange process includes the following steps:

[0168] S1001 : In response to an energy exchange instruction in a power market, determining a total remaining energy value of all energy accounts.

[0169] In some embodiments, the energy bank monitors the pre-stored electric energy values ​​on all energy accounts through a monitoring platform. Upon receiving an energy exchange instruction from the electricity market, the cloud service will determine the total remaining energy value of all energy accounts.

[0170] S1002: Determine the energy guarantee value and the target exchange energy value according to the preset guarantee ratio.

[0171] In some embodiments, the cloud service uses x% of the total remaining energy value as the energy guarantee value, for example, 20% of the total remaining energy value as the energy guarantee value, and determines the remaining (1-x%) of the total remaining energy value as the target exchange energy value.

[0172] S1003: Perform energy exchange in the electricity market based on the target exchange energy value.

[0173] In some embodiments, the energy bank can use the target exchange energy as the main body to participate in electricity market transactions or peak shaving and valley filling to improve the utilization rate of electric energy resources.

[0174] In a specific example, users can charge their electric vehicles through slow charging at night or in their spare time when electricity prices are low, and then decide the amount of energy that can be transferred based on their own driving habits. For example, if an electric vehicle has 100kWh, and the user's daily commuting needs 60kWh, the remaining 40kWh can be stored in the energy bank's energy account through a fast charging or super charging device, with a storage time of ≤15 minutes. When the electric vehicle urgently needs to be charged, a fast charging or super charging device can be selected to extract the pre-stored energy from the energy storage device to recharge the electric vehicle without paying any fees.

[0175] The energy management method in this embodiment allows users to quickly store excess electricity, allowing them to withdraw it directly when needed without paying any fees. This effectively mitigates the risk of increased electricity recharge costs due to significant price increases. When electricity is urgently needed, they can also quickly withdraw electricity for recharge, making the entire process efficient and convenient. Energy banks can utilize managed energy resources to participate in electricity market transactions or generate profits by shaving peaks and filling valleys. For example, they can discharge electricity from the grid during peak electricity prices and draw energy from the grid to charge energy storage devices during low electricity prices. This effectively improves the profitability of energy banks and the utilization rate of energy resources.

[0176] It should be understood that, although the various steps in the flowcharts involved in the various embodiments described above are displayed in sequence according to the instructions of the arrows, these steps are not necessarily executed 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 executed 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 executed and completed at the same time, but can be executed at different times, and the execution order of these steps or stages is not necessarily to be carried out in sequence, but can be executed in turn or alternately with other steps or at least a portion of steps or stages in other steps.
