Description

Technical Field

[0001] The present application relates to the field of power supply technology for battery swap stations in the new energy industry, and in particular to a method and system for metering electric energy at battery swap stations. Background Art

[0002] With the gradual popularization of battery swap station technology in the field of new energy electric vehicles, some battery swap stations deployed in high-frequency demand areas are often in a state of supply exceeding demand. At present, the battery compartment of the battery swap station allows battery swapping only when the battery is fully charged. Alternatively, users can contact the station specialist through APP or other means to inform them that they can accept non-fully charged batteries, and after arriving at the station, the station specialist will manually help to jump the queue for replacement. The former strictly constrains the full charge state, resulting in a relatively small average daily number of battery swaps for a single battery compartment in the battery swap station and insufficient flexibility. Although the latter can realize battery swapping when the battery is not fully charged, it requires users to perform more complex operations and communication is not smart and convenient enough.

[0003] It can be seen that the current battery swap service functions of battery swap stations cannot well meet the usage needs in high-frequency demand scenarios. Summary of the Invention

[0004] The present application provides an energy metering method and system for battery swap stations, which are exclusively optimized for high-frequency demand scenarios. It considers dynamically allocating batteries that meet the user's driving needs after battery swapping based on the user's minimum required mileage, and no longer solidifies the constraints of fully charged battery swapping. In this way, under the premise of meeting user needs, the batteries in the battery compartment of the battery swap station do not need to occupy the charging compartment for too long in a slow charging state, thereby improving the charging conversion rate of the battery compartment per unit time, thereby improving the operational efficiency of the battery compartment, which is conducive to improving the system flexibility, intelligence and convenience, while improving operational efficiency.

[0005] In a first aspect, the present application provides a method for metering electric energy at a battery swap station, which is applied to a server of a battery swap station operation and maintenance system. The battery swap station operation and maintenance system includes a first local management terminal of a first battery swap station and the server. The method includes:

[0009] querying the supercharging curve mapping relationship table according to the first basic attribute of the first battery currently placed in the battery compartment of the first battery swap station to obtain a first supercharging curve corresponding to the first battery;

[0010] Based on the location information of the vehicle to be replaced, the charging status parameters of the first battery, the first basic attributes, the first supercharging curve, and the reference required power, a recommended allocation plan between the first battery and the vehicle to be replaced is determined, and the recommended allocation plan is published to the first local management terminal and the battery replacement demand side terminal.

[0011] In a second aspect, an embodiment of the present application provides a battery swap station operation and maintenance system, including a server, a first local management terminal, and a battery swap demand-side terminal, wherein:

[0012] The server is configured to execute the steps executed by the server in the first aspect of the embodiment of the present application;

[0013] The first local management terminal is configured to execute the steps executed by the first local management terminal in the first aspect of the embodiment of the present application;

[0014] The battery exchange demand side terminal is used to execute the steps performed by the battery exchange demand side terminal in the first aspect of the embodiment of this application.

[0015] It can be seen that in the embodiment of the present application, the server counts the historical charging metering data of multiple battery swap stations for charging the batteries in the battery compartment, and the multiple battery swap stations include the first battery swap station; the historical charging metering data is analyzed to obtain the correspondence between the basic attributes of the battery and the supercharging curve; and, based on the obtained correspondence, a supercharging curve mapping relationship table is created, the basic attributes include battery model and battery full charge, and the supercharging curve is a curve of battery state of charge SOC changing with time; the battery swap demand information of the vehicle to be swapped assigned to the first battery swap station is determined; and the reference demand power is determined based on the battery swap demand mileage in the battery swap demand information and the historical driving power consumption of the vehicle to be swapped; based on the first basic attribute of the first battery currently placed in the battery compartment of the first battery swap station, the supercharging curve mapping relationship table is queried to obtain the first supercharging curve corresponding to the first battery; based on the location information of the vehicle to be swapped, the charging state parameters of the first battery, the first basic attribute, the first supercharging curve, and the reference demand power, a recommended allocation plan between the first battery and the vehicle to be swapped is determined, and the recommended allocation plan is published to the first local management terminal and the battery swap demand side terminal. In this way, compared with the existing battery swap allocation strategy, this application no longer solidifies the constraints of fully charged battery swapping, and considers dynamically allocating batteries that meet the user's driving needs after battery swapping based on the user's minimum required mileage, solving the current problem of low energy utilization efficiency caused by the single management of battery swap stations and the requirement to wait until the battery is fully charged before swapping, thereby improving overall energy utilization efficiency and convenience.

[0023] In order to enable those skilled in the art to better understand the present invention, the following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0024] The terms "first," "second," and the like in the specification and claims of this application and the accompanying drawings are used to distinguish between different objects, not to describe a particular order. Furthermore, the terms "including," "having," and any variations thereof, are intended to cover non-exclusive inclusions. For example, a process, method, system, product, or apparatus comprising a series of steps or elements is not limited to the listed steps or elements but may optionally include steps or elements not listed, or may optionally include other steps or elements inherent to the process, method, product, or apparatus.

[0025] References herein to "embodiments" mean that a particular feature, structure, or characteristic described in connection with the embodiments may be included in at least one embodiment 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.

[0026] In the embodiments of this application, "and / or" describes the relationship between associated objects and indicates that three relationships can exist. For example, "A and / or B" can represent the following three situations: A exists alone; A and B exist simultaneously; and B exists alone. A and B can be singular or plural.

[0027] In the embodiments of the present application, the symbol " / " can indicate that the preceding and following objects are in an "or" relationship. In addition, the symbol " / " can also represent a division sign, that is, performing a division operation. For example, A / B can mean A divided by B.

[0028] In the embodiments of the present application, "at least one item" or similar expressions refers to any combination of these items, including any combination of single items or plural items, and refers to one or more, and multiple refers to two or more. For example, at least one item (item) of a, b, or c can represent the following seven situations: a, b, c, a and b, a and c, b and c, a, b, and c. Among them, each of a, b, and c can be an element or a set containing one or more elements.

[0029] In the embodiments of this application, "equal to" can be used in conjunction with "greater than" and is applicable to the technical solution adopted when "greater than" is used, and can also be used in conjunction with "less than" and is applicable to the technical solution adopted when "less than" is used. When "equal to" is used in conjunction with "greater than", it should not be used in conjunction with "less than"; when "equal to" is used in conjunction with "less than", it should not be used in conjunction with "greater than".

[0030] Currently, in the existing battery swap distribution plan, the condition for the battery compartment to allow battery swapping is that the battery is in a fully charged state. Alternatively, the user can contact the station specialist through APP or other means to inform them that they can accept non-fully charged batteries, and after arriving at the station, the station specialist will manually help to jump the queue for replacement. The former strictly constrains the full charge state, resulting in a relatively small average daily number of battery swaps for a single battery compartment in the battery swap station and insufficient flexibility. Although the latter can realize partially charged battery swaps, it requires users to perform more complex operations and the communication is not smart and convenient enough, making it difficult to meet the use needs of battery swaps in high-frequency demand scenarios.

[0031] In response to the above problems, an embodiment of the present application provides a method and system for metering electric energy at a battery swap station. The embodiment of the present application is described in detail below with reference to the accompanying drawings.

[0032] See also Figure 1 , Figure 1 This is a system architecture diagram of a battery swap station operation and maintenance system provided by an embodiment of the present application, such as Figure 1 As shown, the system architecture diagram of the battery swap station operation and maintenance system includes a server 101, a first local management terminal 102 and a battery swap demand side terminal 103, and the server 101 is connected to the first local management terminal 102 and the battery swap demand side terminal 103 respectively.

[0033] Among them, the first local management terminal 102 can be an industrial tablet computer or an embedded terminal device integrated in the control cabinet of the first battery swap station, which is responsible for the relevant management operations of the first battery swap station. The first local management terminal 102 is mainly used to monitor the status of the first battery and the operation of the charging equipment in the first battery swap station in real time; and to send battery swap demand information to the server 101, including the required battery swap mileage, vehicle location, remaining available mileage, etc.; and to receive the recommended allocation plan between the first battery and the vehicle to be swapped sent by the server 101, and perform related battery allocation, battery swap operation arrangement and other tasks in the first battery swap station. It is the executor of the server 101's decision at the local battery swap station, which is conducive to ensuring that the battery swap service can be smoothly implemented at the first battery swap station.

[0034] Among them, the battery swap demand side terminal 103 is the entrance for users to interact with the battery swap station operation and maintenance system, including the vehicle terminal of the vehicle to be swapped or the mobile terminal registered for the vehicle to be swapped, such as the central control screen inside the vehicle body, smart phone, laptop computer, tablet computer, etc. The battery swap demand side terminal 103 is used to receive the battery swap demand instruction input by the user; and to respond to the battery swap demand instruction, send battery swap demand information to the server 101, including the battery swap demand mileage, vehicle location, remaining available mileage, etc.; and to feedback the remaining available mileage and location information of the vehicle to be swapped to the server 101. This information plays an important role in the server 101 screening the battery swap demand information and determining the recommended allocation plan.

[0035] Among them, the server 101 is used to count the historical charging metering data of batteries in the battery compartments of multiple battery swap stations, and conduct in-depth analysis of these data, so as to establish a correspondence between the basic properties of the battery and the supercharging curve, and then create a supercharging curve mapping relationship table; and, it is used to determine the battery swap demand information of the vehicle to be swapped assigned to the first battery swap station, and calculate the reference demand power based on multiple factors, query the supercharging curve, and perform complex allocation scheme optimization operations, and finally determine and recommend the allocation scheme to the first local management terminal 102 and the battery swap demand side terminal 103; and, it is used to screen the battery swap demand information and coordinate the battery swap demand allocation between the first battery swap station and the adjacent second battery swap station according to different situations.

[0036] It can be seen that in this embodiment, the server 101 is exclusively optimized for high-frequency demand scenarios, and considers dynamically allocating batteries that meet the user's driving needs after battery replacement based on the user's minimum required mileage, and no longer solidifies the constraints of fully charged battery replacement. In this way, under the premise of meeting user needs, the batteries in the battery compartment of the battery swap station do not need to occupy the charging compartment for too long in a slow charging state, thereby improving the charging conversion rate of the battery compartment per unit time, and thus improving the operational efficiency of the battery compartment, which is conducive to improving the flexibility, intelligence and convenience of the system, while improving operational efficiency.

[0037] See also Figure 2 , Figure 2 This is a block diagram of an electronic device provided in an embodiment of the present application, for executing Figure 1 The battery swap station operation and maintenance system in Figure 2 As shown, the electronic device 20 may include one or more of the following components: a memory 23, a processor 21, a communication bus 30, a communication interface 22, and one or more programs 231. The one or more programs 231 are stored on the memory 23 and are configured to be executed by the processor 21. The one or more programs 231 include instructions for executing any step in the following method embodiments. In a specific implementation, the processor 21 is used to execute any step in the following method embodiments, and when performing data transmission such as sending, the communication interface 22 may be selectively called to complete the corresponding operation. The electronic device 20 may be a mobile phone terminal, a tablet computer, a laptop computer, or a wearable smart device.

[0038] The processor 21 may include one or more processing cores. The processor 21 utilizes various interfaces and circuits to connect the various components within the electronic device 20. It executes instructions, programs, code sets, or instruction sets stored in the memory 23, as well as accesses data stored in the memory 23, to perform various functions and process data within the electronic device 20. Optionally, the processor 21 may be implemented using at least one of the following hardware forms: a digital signal processing (DSP), a field-programmable gate array (FPGA), or a programmable logic array (PLA). The processor 21 may integrate one or a combination of a central processing unit (CPU), a graphics processing unit (GPU), and a modem. The CPU primarily processes the operating system, user interface, and application programs; the GPU is responsible for rendering and drawing display content; and the modem handles wireless communications. It is understood that the modem may not be integrated into the processor 21 and may be implemented separately via a communication chip.

[0039] The memory 23 may include a random access memory (RAM) or a read-only memory (ROM). The memory 23 may be used to store instructions, programs, codes, code sets, or instruction sets. The memory 23 may include a program storage area and a data storage area, wherein the program storage area may store instructions for implementing an operating system, instructions for implementing at least one function (such as a touch function, a sound playback function, an image playback function, etc.), instructions for implementing the above-mentioned various method embodiments, etc. The data storage area may also store data created by the electronic device 20 during use.

[0040] It is understandable that the electronic device 20 may include more or fewer structural elements than those in the above structural block diagram, for example, a power module, physical buttons, a Wi-Fi module, a speaker, a Bluetooth module, a sensor, etc., which are not limited here.

[0041] See also Figure 3 , Figure 3 This is an overall flow chart of a method for measuring electric energy in a battery swap station provided by an embodiment of the present application, which is applied to Figure 1 Server 101 in, such as Figure 3 As shown, the method includes the following steps:

[0042] Step S301, collecting historical charging metering data of batteries in battery compartments charged by multiple battery swap stations, wherein the multiple battery swap stations include the first battery swap station.

[0043] Among them, the historical charging metering data at least includes basic battery attribute data, charging process data, and environment and usage related data.

[0044] Specifically, basic battery attribute data includes the battery model and full charge capacity. Performance differences between different battery models affect charging metering. Furthermore, the full charge capacity represents the amount of energy a battery can store when fully charged. Batteries with different full charges will inevitably experience different increases in charge and speed under the same charging conditions, resulting in distinct supercharge curves. Therefore, accurately recording the battery's full charge capacity is crucial for determining the supercharge curve mapping table.

[0045] Specifically, charging process data includes the starting and ending state of charge (SOC), charging time, charging current, and voltage. The starting and ending SOC of each charge accurately reflect the range of battery charge variation during a single charge, forming a key component of the supercharge curve. Furthermore, charging time represents the duration from the start to the end of each charge. Different charging times correspond to different increases in charge. For example, a fast charge from 20% SOC to 80% SOC may take only 30 minutes, while a slow charge may take two hours. The length of the charging time directly affects the slope of the supercharge curve, i.e., the change in charging speed. Furthermore, charging current and voltage are used to calculate charging power, and changes in charging power directly affect the trend of the supercharge curve. For example, in the early stages of charging, the battery may charge rapidly at a high power, at which point the current and voltage are relatively stable, resulting in a steep supercharge curve. As the battery approaches full charge, the charging power gradually decreases to protect the battery, and the current and voltage also change accordingly, making the supercharge curve flatter.

[0046] Specifically, environment-related data includes charging environment temperature and vehicle driving condition data. Charging environment temperature has a significant impact on the chemical reaction rate within the battery, which in turn plays an important role in charging efficiency and supercharge curves. For example, in low-temperature environments, charging speed slows significantly, the slope of the supercharge curve decreases, and charging time is prolonged. Conversely, in high-temperature environments, charging speed may increase, but excessively high temperatures may also cause battery safety issues such as thermal runaway, and also affect battery life, causing the supercharge curve to exhibit different trends. Vehicle driving condition data includes data such as vehicle mileage, driving speed, and road conditions (such as urban congestion, highway driving, etc.). These data can reflect the battery's discharge status. Different discharge conditions will result in different initial states and charging requirements for the battery during charging, which in turn affects the supercharge curve.

[0047] It can be seen that in this embodiment, the server can obtain the historical charging metering data of the batteries in the battery swap compartments in multiple battery swap stations by interconnecting with the first local management terminal and the battery swap demand side terminal, and then conducting data exchange, so as to perform data statistics and analysis, and obtain the correspondence between different types of batteries and supercharging curves, which is conducive to determining the recommended allocation plan for the first battery according to the supercharging curve and battery swap demand, and is conducive to improving energy utilization efficiency.

[0048] Step S302: Analyze the historical charging metering data to obtain a correspondence between basic attributes of the battery and a supercharge curve; and create a supercharge curve mapping relationship table based on the obtained correspondence, wherein the basic attributes include the battery model and the battery full charge, and the supercharge curve is a curve showing the battery state of charge (SOC) changing over time.

[0049] In a possible embodiment, analyzing the historical charging metering data to obtain a correspondence between the basic properties of the battery and the supercharging curve includes:

[0050] Performing reference processing on the historical charging metering data, wherein the reference processing includes data cleaning and data preprocessing, and the data preprocessing includes standardization processing;

[0051] Dividing the historical charging metering data after the reference processing into multiple historical charging metering data groups, each historical charging metering data group includes multiple historical charging metering data corresponding to multiple batteries, the basic attributes corresponding to the multiple batteries are the same, and the basic attributes corresponding to the multiple batteries in any two historical charging metering data groups are different;

[0052] For each of the plurality of historical charging metering data groups, determining a supercharging curve corresponding to the historical charging metering data group according to the plurality of historical charging metering data corresponding to the plurality of batteries, to obtain a plurality of supercharging curves;

[0053] A one-to-one correspondence between the basic attributes of the battery and the supercharging curves is determined according to the multiple historical charging metering data groups and the multiple supercharging curves.

[0054] For example, the historical charging metering data of all batteries with model A and a full charge of 50kwh are classified into group a; the historical charging metering data of batteries with model B and a full charge of 80kwh are classified into group b; and the historical charging metering data of batteries with model C and a full charge of 90kwh are classified into group c. Through statistical analysis of the historical charging metering data, it is found that under specific charging conditions, it takes 30 minutes for the A-type battery in group a to charge from 20% SOC to 80% SOC. The relationship between the power change and time in this process constitutes the supercharging curve of the A-type battery. By analogy, the supercharging curve of the B-type battery and the supercharging curve of the C-type battery can be obtained respectively. Such relationships of different types of batteries are sorted out to obtain a supercharging curve mapping relationship table.

[0055] Step S303: determine the battery swapping demand information of the vehicle to be battery swapped that is assigned to the first battery swapping station; and determine the reference required power according to the battery swapping demand mileage in the battery swapping demand information and the historical driving power consumption of the vehicle to be battery swapped.

[0056] Among them, the reference required power refers to the power value calculated based on the battery replacement mileage of the vehicle to be replaced and its historical driving power consumption, which is used to measure the power required for the vehicle to complete the desired journey.

[0057] Specifically, in practical applications, the reference power demand is an important reference data for the battery swap station operation and maintenance system to determine the battery allocation plan. Taking a vehicle to be swapped as an example, if its battery swap mileage is 150 kilometers, and through statistical analysis of the vehicle's historical driving data, it is found that its average power consumption per kilometer is 1.2 degrees. Then, using the formula "reference power demand = battery swap mileage × historical driving power consumption", it can be calculated that the reference power demand of the vehicle is 150×1.2=180 degrees. This 180 degrees of power is the value that the system needs to focus on when allocating batteries to it, so as to ensure that the allocated battery power can meet the basic driving needs of the vehicle.

[0058] In a possible embodiment, determining the battery swapping demand information allocated to the first battery swapping station includes:

[0059] Acquire multiple battery swap demand information from multiple battery swap demand-side terminals, where the battery swap demand-side terminals include a vehicle terminal of a vehicle to be battery swapped or a mobile terminal that registers the vehicle to be battery swapped;

[0060] Obtaining the remaining available mileage of the vehicle to be battery-swapped and the location information of the battery-swapped demand-side terminal;

[0061] Obtaining a reference location range mapped by the location information of the first battery swap station;

[0062] Filtering out first battery swap demand information from the multiple battery swap demand information, the first battery swap demand information having the position information within the reference position range and the remaining available mileage being able to reach the first battery swap station;

[0063] Determine whether a difference between the number of first battery swapping demand information and the number of first batteries at the first battery swapping station is less than a preset value;

[0064] If it is detected that the value is less than the preset value, marking the first battery swap demand information as the battery swap demand information assigned to the first battery swap station;

[0065] If it is detected that the value is not less than the preset value, the battery exchange load status of the second battery exchange station adjacent to the first battery exchange station is obtained; and based on the battery exchange load status and the remaining available mileage of the vehicle to be battery exchanged, the location information of the battery exchange demand side terminal and the location information of the second battery exchange station, the battery exchange demand information in the first battery exchange demand information that is allocated to the first battery exchange station is determined.

[0066] In a possible embodiment, obtaining a reference location range mapped by the location information of the first battery swap station includes:

[0067] Obtaining location information of the first battery swap station;

[0068] Determine a geographical area centered on the first battery swap station according to the location information of the first battery swap station and a preset boundary shape and size, and determine the geographical area as the reference location range;

[0069] The road condition and traffic congestion situation of the current time period are acquired in real time, and the boundary shape and size of the reference position range are dynamically adjusted according to the road condition and the traffic congestion situation, wherein the road condition includes a high-speed road section and a non-high-speed road section.

[0070] In a possible embodiment, the traffic congestion conditions include no congestion, general congestion, moderate congestion, and severe congestion; and dynamically adjusting the boundary shape and size of the reference location range according to the road condition and the traffic congestion conditions includes:

[0071] If it is determined that the road condition is the non-highway section, obtaining a reference boundary shape and a reference boundary size corresponding to the traffic congestion condition, and adjusting the reference position range according to the reference boundary shape and the reference boundary size; and

[0072] If it is determined that the road condition is the expressway section, a plurality of expressway section partitions are divided according to the data of the expressway section, and a geographic fence is set with the first battery swap station as the center according to the plurality of expressway section partitions and the location information of the first battery swap station; and

[0073] The boundary shape and size of the geo-fence are adjusted according to the traffic congestion situation corresponding to the current time period.

[0074] It is understandable that the reference location range mapped by the location information of the first battery swap station is an area determined by the location signal of the first battery swap station and a preset boundary shape and size. For example, a circular area or polygonal area with different radii is set as the reference range with the battery swap station as the center. In addition, the reference location range is dynamically adjusted according to the traffic congestion in different time periods. For example, during peak traffic hours, the range is narrowed to ensure that the vehicle can arrive within a reasonable time; and the reference location range is dynamically adjusted according to different road conditions. For example, on highways, battery swap stations are arranged along the highway (generally integrated charging and battery swap stations, which can be charged and swapped, or only support battery swapping). The battery swap demand information can be partitioned according to the geographic fence of the publishing location.

[0075] In one possible embodiment, the battery swap load status is used to characterize the reservation status and battery status of the second battery of the second battery swap station; the determining of the battery swap demand information allocated to the first battery swap station in the first battery swap demand information based on the battery swap load status and the remaining available mileage of the vehicle to be battery swapped, the location information of the battery swap demand-side terminal, and the location information of the second battery swap station includes:

[0076] Determine at least one vehicle to be battery-swapped that can travel to the second battery-swapped station based on the remaining available mileage of the vehicle to be battery-swapped, the location information of the battery-swapped demand-side terminal, and the location information of the second battery-swapped station;

[0077] Determine the battery status of the unreserved batteries at the second battery swap station according to the battery swap load status;

[0078] Determining, according to the battery status of the unreserved battery, one or more vehicles to be replaced with batteries among the at least one vehicle to be replaced with batteries that can be replaced with batteries upon arrival at the station;

[0079] Determine that the first battery swap demand information after excluding the first battery swap demand information of the one or more vehicles to be battery swapped in the first battery swap demand information is the battery swap demand information assigned to the first battery swap station.

[0080] Among them, the server is connected to the local management terminal of the second battery swap station, and is used to obtain the battery swap load status and location information of the second battery of the second battery swap station.

[0081] In a possible embodiment, the determining, based on the battery status of the unreserved battery, one or more vehicles to be replaced with batteries among the at least one vehicle to be replaced with batteries that can be replaced upon arrival at the station includes:

[0082] Determining a reference arrival time for each of the one or more vehicles to be battery-swapped to arrive at the second battery-swapped station;

[0083] determining the power level of each unreserved battery at the reference arrival time according to the battery status of the unreserved battery;

[0084] The vehicle to be replaced with a battery whose power level is greater than the reference required power level is marked as a vehicle that can be replaced upon arrival at the station.

[0085] For example, the reference location range of the first battery swap station can be an area with a radius of 10 kilometers centered on it, with 10 battery swap demand information. Among them, the positions of the first vehicle, the second vehicle, the third vehicle, the fourth vehicle, and the fifth vehicle corresponding to 5 of the information are within the range and have the remaining available mileage to reach the first battery swap station. These 5 are the first battery swap demand information. If the first battery swap station has 3 batteries, 5-3=2 is greater than the preset value 1. At this time, the battery swap load status of the adjacent second battery swap station is obtained. For example, the second battery swap station has 2 unreserved batteries. According to information such as the location of the vehicle to be swapped and the second battery swap station, it is determined that the second vehicle and the third vehicle can go to the second battery swap station and can swap batteries upon arrival. Then, the first battery swap demand information corresponding to the remaining first vehicle, fourth vehicle, and fifth vehicle is allocated to the first battery swap station.

[0086] It can be seen that in this embodiment, through the interconnection between the server and the local management terminals of the first battery swap station and the second battery swap station, the battery swap demand information of the vehicles to be swapped assigned to the first battery swap station can be determined, and some of the vehicles to be swapped can be intelligently allocated to the second battery swap station, which is conducive to coordinating the allocation of energy and improving the flexibility and convenience of allocation.

[0087] Step S304: According to the first basic attribute of the first battery currently placed in the battery compartment of the first battery swap station, query the supercharging curve mapping relationship table to obtain the first supercharging curve corresponding to the first battery.

[0088] Step S305: Determine the recommended allocation plan between the first battery and the vehicle to be replaced based on the location information of the vehicle to be replaced, the charging status parameters of the first battery, the first basic attributes, the first supercharging curve, and the reference required power, and publish the recommended allocation plan to the first local management terminal and the battery replacement demand side terminal.

[0089] In a possible embodiment, determining a recommended allocation scheme between the first battery and the vehicle to be replaced based on the location information of the vehicle to be replaced, the charging state parameter of the first battery, the first basic attribute, the first supercharging curve, and the reference required power includes:

[0090] Determine a reference required power SOC according to the first basic attribute and the reference required power;

[0091] Determining an estimated battery replacement time for the vehicle to be replaced based on the location information of the vehicle to be replaced, the location information of the first battery replacement station, and traffic map information;

[0092] Determining a target state of charge (SOC) of the first battery at the expected battery replacement time and an actual charged amount of the first battery according to the state of charge parameter of the first battery and the first supercharge curve;

[0093] Determine the maximum chargeable capacity of the battery compartment under continuous charging conditions according to the first supercharging curve and the estimated battery replacement time;

[0094] According to the target power SOC, the actual charged power, and the maximum rechargeable power, an allocation scheme optimization operation is performed with the degree to which the required mileage is met and the battery compartment charging conversion efficiency as constraints to obtain a recommended allocation scheme between the first battery and the vehicle to be replaced.

[0095] For example, the estimated battery replacement time is 1 hour later, and the current SOC of the first battery is 30%. According to the supercharging curve, it can be charged to 60% in 1 hour, that is, the target power SOC is 60%. At the same time, the actual charged power within this 1 hour is calculated, and the maximum rechargeable power of the battery compartment that can be continuously charged within 1 hour is calculated according to the supercharging curve.

[0096] In a possible embodiment, determining the maximum chargeable capacity of the battery compartment under continuous charging conditions according to the first supercharging curve and the estimated battery replacement time includes:

[0097] Determining an average charging speed of the state of charge (SOC) in a reference SOC section according to the first supercharging curve, wherein the reference SOC section is a high-frequency charging section obtained based on statistical analysis of historical charging data;

[0098] Based on the average charging speed and the duration between the current system time and the expected battery replacement time, the maximum rechargeable capacity of the battery compartment under continuous charging conditions is determined.

[0099] In one possible embodiment, the allocation scheme optimization operation is performed based on the target SOC, the actual charged power, and the maximum rechargeable power, with the degree to which the required mileage is satisfied and the battery compartment charging conversion efficiency as constraints, to obtain a recommended allocation scheme between the first battery and the vehicle to be replaced, including:

[0100] According to the constraint that each vehicle to be battery-swapped is allocated at most a single first battery, and the first batteries of any two vehicles to be battery-swapped that are configured with batteries must be different, an allocation plan is created for the first battery of the first battery-swapped station and the vehicles to be battery-swapped, to obtain multiple allocation plans;

[0101] For each allocation plan, the degree to which the required mileage is met and the battery compartment charging conversion efficiency are calculated and processed comprehensively to obtain the comprehensive adaptability of each allocation plan;

[0102] The allocation scheme with the highest comprehensive adaptability is selected as the recommended allocation scheme between the first battery and the vehicle to be replaced.

[0103] For example, if there are three vehicles to be replaced and three first batteries, multiple allocation plans are created, and the degree to which the required mileage is met and the battery compartment charging conversion efficiency in each plan are calculated. For example: In plan one, the first vehicle is allocated the first battery, the second vehicle is allocated the second battery, and the third vehicle is allocated the third battery. The comprehensive adaptability of various indicators under the plan is calculated, and all plans are compared, and the plan with the highest comprehensive adaptability is selected as the recommended plan.

[0104] In one possible embodiment, for each allocation scheme, the degree to which the required mileage is satisfied and the battery compartment charging conversion efficiency are calculated and processed comprehensively to obtain the comprehensive adaptability of each allocation scheme, including:

[0105] For each first battery in the currently processed allocation scheme and its corresponding vehicle to be replaced, the following steps are performed to obtain the degree to which multiple required mileages are satisfied: determining the expected power at the expected replacement time based on the target power SOC of the currently processed first battery and the first basic attribute of the currently processed first battery; dividing the expected power by the reference required power of the vehicle to be replaced to obtain the degree to which the required mileage of the currently processed first battery is satisfied;

[0106] Determining a degree of satisfaction of the comprehensive mileage requirement of the first battery swap station according to the satisfaction degrees of the multiple mileage requirement requirements;

[0107] For each first battery in the currently processed allocation scheme and its corresponding vehicle to be replaced, perform the following steps to obtain multiple battery compartment charging conversion efficiencies: obtain the actual charged power of the currently processed first battery and the maximum chargeable power of the battery compartment to which the first battery belongs; and determine the battery compartment charging conversion efficiency based on the actual charged power and the maximum chargeable power;

[0108] Determine the comprehensive battery compartment charging conversion efficiency of the first battery swap station based on the multiple battery compartment charging conversion efficiencies;

[0109] The comprehensive adaptability of each allocation scheme is determined based on the preset weight coefficient, the degree to which the comprehensive required mileage is met, and the comprehensive battery compartment charging conversion efficiency.

[0110] In a possible embodiment, determining the degree to which the comprehensive required mileage of the first battery swap station is satisfied according to the multiple required mileages satisfied degrees includes:

[0111] determining a first number of the plurality of required mileages to be satisfied to a degree of 1;

[0112] determining a second amount of the extent to which the plurality of required miles are satisfied;

[0113] The degree to which the comprehensive required mileage of the first battery swap station is met is determined based on the first number and the second number.

[0114] For example, there may be 3 vehicles to be replaced and 3 first batteries, and then six allocation schemes may be created. Under each allocation scheme, the degree to which the required mileage of each vehicle to be replaced is satisfied and the degree to which the comprehensive required mileage is satisfied are shown in the following Table 1:

[0115] Table 1. Comprehensive demand mileage satisfaction degree table

[0116] Allocation Plan The first vehicle to be replaced The second vehicle to be replaced The third vehicle to be replaced The degree to which the required mileage of the first vehicle to be replaced is met The degree to which the required mileage of the second vehicle to be replaced is met The degree to which the required mileage of the third vehicle to be replaced is met Comprehensive demand mileage satisfaction Option 1 First battery A First battery B First battery C 0.8 0.9 0.7 0.8 Option 2 First battery A First battery C First battery B 0.8 0.7 0.85 0.78 Option 3 First battery B First battery A First battery C 0.75 0.85 0.7 0.77 Option 4 First battery B First battery C First battery A 0.75 0.7 0.8 0.75 Plan 5 First battery C First battery A First battery B 0.7 0.85 0.8 0.78 Plan 6 First battery C First battery B First battery A 0.7 0.9 0.8 0.8

[0117] For example, under each allocation scheme, the battery compartment charging conversion efficiency and the comprehensive battery compartment charging conversion efficiency corresponding to each vehicle to be replaced are shown in the comprehensive battery compartment charging conversion efficiency table in Table 2 below:

[0118] Table 2. Comprehensive battery compartment charging conversion efficiency table

[0119] Allocation Plan The first vehicle to be replaced The second vehicle to be replaced The third vehicle to be replaced The charging conversion efficiency of the battery compartment of the first vehicle to be replaced The battery compartment charging conversion efficiency of the second vehicle to be replaced The charging conversion efficiency of the battery compartment of the third vehicle to be replaced Comprehensive battery compartment charging conversion efficiency Option 1 First battery A First battery B First battery C 0.7 0.8 0.75 0.75 Option 2 First battery A First battery C First battery B 0.75 0.8 0.7 0.75 Option 3 First battery B First battery A First battery C 0.8 0.7 0.75 0.75 Option 4 First battery B First battery C First battery A 0.7 0.75 0.8 0.75 Plan 5 First battery C First battery A First battery B 0.75 0.7 0.8 0.75 Plan 6 First battery C First battery B First battery A 0.75 0.8 0.7 0.75

[0120] For example, the preset weight coefficients corresponding to the degree of satisfaction of the comprehensive required mileage and the comprehensive battery compartment charging conversion efficiency may be 0.6 and 0.4, respectively. The comprehensive fitness corresponding to each allocation scheme is shown in the comprehensive fitness table in Table 3 below:

[0121] Table 3. Comprehensive fitness table

[0122] Allocation Plan The first vehicle to be replaced The second vehicle to be replaced The third vehicle to be replaced Comprehensive demand mileage satisfaction Comprehensive battery compartment charging conversion efficiency Comprehensive fitness Option 1 First battery A First battery B First battery C 0.8 0.75 0.78 Option 2 First battery A First battery C First battery B 0.78 0.75 0.768 Option 3 First battery B First battery A First battery C 0.77 0.75 0.762 Option 4 First battery B First battery C First battery A 0.75 0.75 0.75 Plan 5 First battery C First battery A First battery B 0.78 0.75 0.768 Plan 6 First battery C First battery B First battery A 0.8 0.75 0.78

[0123] It can be seen that in this embodiment, exclusive optimization is performed for high-frequency demand scenarios, and the battery that meets the user's driving needs after battery replacement is dynamically allocated according to the user's minimum required mileage, and the constraint conditions that restrict battery replacement with full power are no longer solidified. In this way, under the premise of meeting user needs, the batteries in the battery compartment of the battery swap station do not need to occupy the charging compartment for too long in a slow charging state, thereby improving the charging conversion rate of the battery compartment per unit time, and then improving the operational efficiency of the battery compartment, which is conducive to improving the flexibility, intelligence and convenience of the system, while improving operational efficiency.

[0124] See also Figure 4 , Figure 4 This is a display interface diagram of a battery replacement demand side terminal provided in an embodiment of the present application, such as Figure 4 As shown, the display interface diagram of the battery swap demand side terminal is a schematic diagram of the battery swap station search interface of the user side mobile terminal.

[0125] Among them, the battery swap demand side terminal includes but is not limited to the user side mobile terminal, and may also include the vehicle terminal of the vehicle to be swapped. The user side mobile terminal is registered and bound to the vehicle to be swapped. Furthermore, the user side mobile terminal includes an application product such as a small program or APP that can register and bind the vehicle to be swapped. When the user has a charging demand while driving the vehicle, he can log in to the application interface and search for nearby battery swap stations, which will present the following information: Figure 4 The battery swap station search interface shown.

[0126] Specifically, the upper middle part of the battery swap station search interface is the map route interface, which identifies the current location of the vehicle to be battery swapped and the locations of multiple battery swap stations, and highlights the location of the first battery swap station. For example, the identification color and the "preferred battery swap" characters are used to show that the first battery swap station is the best optional battery swap station for the vehicle to be battery swapped; and the right side of the map route interface includes a favorite icon, a positioning icon, a route icon, and a refresh icon from top to bottom, respectively, which support users to perform corresponding operations.

[0127] Furthermore, the lower middle portion of the battery swap station search interface contains brief information about the battery swap stations found. From top to bottom, there is a search bar for searching for nearby battery swap stations. The right side of the search bar contains a filter icon for filtering information about battery swap stations that meet the user's specific needs, such as distance, cost, number of people in line, and rating. The lower side of the search bar includes, from left to right, a comprehensive sorting character, a battery swap station character, a DC charging pile character, and an AC charging pile character. The comprehensive sorting character is used to sort the multiple battery swap stations found, and then the best battery swap stations are presented in sequence. The battery swap station character, DC charging pile character, and AC charging pile character are used by users to directly click and use as keywords to filter battery swap stations. Further down, there is brief information about multiple battery swap stations. After the server obtains the battery swap demand information of the vehicle to be swapped and determines that it is assigned to the first battery swap station, the "preferred" character will be marked in the information column of the first battery swap station.

[0128] It can be seen that in this embodiment, after the server obtains the battery swap demand information of the vehicle to be swapped, it further filters out the relevant information of the first battery swap station allocated to the vehicle to be swapped based on the battery swap demand information and the location information of the vehicle to be swapped, and marks it as the preferred battery swap. Then, it can further calculate the recommended allocation plan between the first battery in the first battery swap station and the vehicle to be swapped based on the supercharging curve, charging status parameters, basic attributes and location information of the battery-swapped vehicle and the required power of the first battery in the first battery swap station, so as to guide the vehicle to be swapped to select the most suitable battery for battery swapping, which is conducive to the coordinated allocation of energy and improves the allocation flexibility and convenience.

[0129] See also Figure 5 , Figure 5 This is another display interface diagram of a battery replacement demand-side terminal provided in an embodiment of the present application, such as Figure 5 As shown, the display interface diagram of the battery exchange demand side terminal is a detailed information display interface diagram of the first battery exchange station of the user side mobile terminal.

[0130] The server determines that the first battery swap station is the ××× fast charging battery swap station. Figure 5 The detailed information display interface shown shows multiple characteristic identifiers of the battery swap station, distance information, comprehensive usage information, current battery usage status information, optimal battery swap prompt information and battery swap start identifier, etc.

[0131] Specifically, the multiple feature identifiers of the first battery swap station include preferred charging, battery swap station 3.0, limited-time free parking, autonomous battery swap, flexible upgrade and return, battery swap parking assistance and shared station; the distance information includes the distance information between the first battery swap station and the current vehicle to be swapped. It can be seen that the first battery swap station is 1.1 kilometers away from the current location; the comprehensive usage information includes the number of available batteries, the total number of people in the queue and the total number of people going there. It can be seen that the first battery swap station has a total of 12 first batteries, of which 3 are available batteries, 0 people are in the queue, and 1 person went there in total; the current battery usage status information includes the usage status and remaining usage time of each battery. It can be seen that the No. 3, No. 5 and No. 6 batteries in the first battery swap station are currently available and the recommendation level is represented by the number of stars below the icon, and the No. 3 battery is the best battery for battery swap and is highlighted by the number of stars, icon background color and icon size.

[0132] Furthermore, the best battery swap prompt information is the prompt information of the best battery swap output in response to the recommended allocation plan after the user-side mobile terminal receives the battery recommendation allocation plan from the server, which is used to prompt the user to go to the best battery swap in the first charging station; and the battery swap start logo is located in the lower right corner of the details information display interface, and the user triggers the logo to perform battery swap; in addition, the lower left corner of the details information display interface also includes a favorites icon, a specialist icon and a surrounding icon. The favorites icon is used to add the first battery swap station to the favorites for quick query after triggering, the specialist icon is used to connect to the hotline of the specialist working in the first battery swap station after triggering, and the surrounding icon is used to query related buildings and equipment around the first battery swap station.

[0133] It can be seen that in the embodiment of the present application, the server determines the recommended allocation plan between the first battery and the vehicle to be replaced, and publishes the recommended allocation plan to the first local management terminal and the battery replacement demand side terminal. After receiving the recommended allocation plan, the battery replacement demand side terminal determines the best battery replacement battery in the first battery replacement station based on the recommended allocation plan, and outputs prompt information of the best battery replacement battery on the details information interface of the first battery replacement station to prompt the user to go to the best battery replacement battery for replacement. In this way, compared with the existing battery replacement allocation strategy, the present application no longer solidifies the constraints of fully charged battery replacement, and considers dynamically allocating batteries that meet the user's driving needs after battery replacement based on the user's minimum required mileage, solving the problem of low energy utilization efficiency caused by the current single management of battery replacement stations and the need to wait until the battery is fully charged before replacing the battery, thereby improving overall energy utilization efficiency and convenience.

[0134] See also Figure 6 , Figure 6 This is an application scenario diagram of a method for measuring electric energy in a battery swap station provided by an embodiment of the present application, such as Figure 6 As shown, the application scenario diagram of the electric energy metering method for the battery swap station is a schematic diagram of the scenario of the first battery swap station.

[0135] Understandably, among existing battery swap stations, Sunshine Stations are widely used for their energy-saving and environmentally friendly features. They not only charge vehicles through photovoltaic power generation, but also interact with the grid to increase the station's operating revenue. Even in the event of a power outage, owners can still charge their vehicles as usual. Furthermore, Sunshine Stations support mini-program positioning and are fully integrated with map apps, solving the problem of users having trouble finding stations.

[0136] in, Figure 6 The scene diagram of the first battery swap station shown includes a power grid, a transformer, a photovoltaic power generation component, a vehicle to be swapped, and a plurality of first batteries, and the plurality of first batteries are distinguished by a plurality of digital labels from 1 to 12.

[0137] Specifically, power from the power grid is processed by a transformer, which steps down the voltage before transmitting it to each of the primary batteries at the charging station. The photovoltaic power generation components convert solar energy into electrical energy, which is then directly supplied to the primary batteries to charge the vehicles. Furthermore, when there is sufficient sunlight, the electricity generated by the photovoltaic components can prioritize meeting the needs of the primary batteries, with excess energy stored in related storage devices. When photovoltaic power generation is insufficient, the power grid provides additional power. In the event of a power outage, if there is sufficient photovoltaic power generation and stored energy, photovoltaic power generation can still be used to power the primary batteries, ensuring normal vehicle charging. Furthermore, excess power can be fed back to the grid for profit.

[0138] It can be seen that in this embodiment, when the battery swap demand-side terminal receives the recommended allocation plan from the server, it can determine the best rechargeable battery in the first battery swap station that best meets the user's required mileage and battery compartment charging conversion efficiency, and guide the user to the best rechargeable battery in the first charging station for charging, for example, Figure 6 As shown, the first battery swap station includes three currently available first batteries, No. 3, No. 5 and No. 6. According to the recommended allocation plan, it can be determined that battery No. 3 is the best charging battery. The battery swap demand side terminal will prompt the user to go to the battery swap position of battery No. 3 for battery swap. In this way, under the premise of meeting user needs, the batteries in the battery compartment of the battery swap station do not need to occupy the charging compartment for too long in a slow charging state, thereby improving the charging conversion rate of the battery compartment per unit time, and then improving the operational efficiency of the battery compartment, which is conducive to improving the flexibility, intelligence and convenience of the system, while improving operational efficiency.
