Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative efforts should fall within the scope of the present application.

[0021] It is to be understood that the terms "first", "second", and the like, used in the description and the claims of the application, as well as the above-described drawings, are used to distinguish similar objects and are not necessarily used to describe a particular sequential or chronological order.

[0022] According to an embodiment of the application, a battery charging method of a vehicle is provided. It is to be understood that the steps shown in the flowchart of the drawings can be executed in a computer system such as a set of computer-executable instructions, and although a logical order is shown in the flowchart, in some cases, the steps shown or described herein can be executed in an order different from that shown herein.

[0023] Figure 1 is a flowchart of a battery charging method of a vehicle according to an embodiment of the application, as shown in Figure 1 The method can comprise the following steps: In step S101, in response to the battery of the vehicle being in a connected state with the charging device, current label information corresponding to the vehicle is obtained, and current power information of the battery is obtained, wherein the current label information is used to indicate the type of the current charging operation to be selected for the battery, and the current power information is used to indicate the power state of the battery at the current time.

[0024] In the technical solution provided in step S101 of the application, the current label information can be used to indicate the type of the current charging operation to be selected for the battery. The current charging operation can include a slow charging operation (referred to as a fixed parking lot slow charging operation) performed on the battery in a fixed parking lot, and a fast charging operation (referred to as an on-the-go frequent fast charging operation) performed on the battery in a temporary parking lot.

[0025] In this embodiment, the current power information can be used to indicate the power state of the battery at the current time. The power state can be displayed in percentage form, for example, if the power state is displayed as 100%, it indicates that the power state of the battery at the current time is full power; if the power state is displayed as 30%, it indicates that the power state of the battery at the current time is insufficient power. This is only an example and is not limited.

[0026] In this embodiment, in response to the battery of the vehicle being in the connected state with the charging device, current tag information corresponding to the vehicle and current power information of the battery are obtained. Optionally, the embodiment identifies the current state of the battery of the vehicle with the charging device, and if it is identified that the current state is the connected state, the current tag information corresponding to the vehicle and the current power information of the battery are obtained.

[0027] Optionally, if it is identified that the current state is the connected state, the current power information of the battery is obtained. For example, if it is identified that the current state is the connected state, the current power information can be obtained by accessing a power detection device of the battery, that is, the power state of the battery at the current time can be obtained, where the power detection device can be a power detector or a power sensor.

[0028] In step S102, in response to the protection mode of the battery being in the started state, current request information of the battery is determined based on the current tag information and the current power information, where the current request information is used to request the charging device to input a current to the battery.

[0029] In the technical solution provided by the above step S102 of the application, the current request information can be used to request the charging device to input a current to the battery. For example, the current request information can be represented by Charge_Current_Request.

[0030] In this embodiment, the protection mode can be a mode for charging protection of the battery during charging of the battery.

[0031] In this embodiment, in response to the battery of the vehicle being in the connected state with the charging device, current tag information corresponding to the vehicle and current power information of the battery are obtained. In response to the protection mode of the battery being in the started state, current request information of the battery is determined based on the current tag information and the current power information.

[0032] Optionally, based on the obtained current tag information and the current power information, the current request information of the battery can be determined if it is detected that the protection mode is in the started state.

[0033] Optionally, detection of whether the protection mode of the battery is in the started state can obtain a first detection result, and judgment of whether the current power information meets preset power information can obtain a judgment result. If the first detection result is that the protection mode is in the started state and the judgment result is that the current power information meets the preset power information, the current request information of the battery can be determined based on the obtained current tag information and the current power information.

[0034] Optionally, based on the obtained current tag information and current battery level information, the battery's current request information can be determined. For example, in a current request database, the current request information can be obtained by looking up the aforementioned current tag information and current battery level information. The current request database can include the tag information corresponding to different vehicles, the mapping relationship between the battery level information of different batteries and different current request information.

[0035] Step S103: In response to the battery receiving the current current corresponding to the current request information from the charging device, the current charging operation is performed on the battery using the current current.

[0036] In the technical solution provided by step S103 of the present invention, the charging device can be a charging gun on a fixed charging parking space or a charging gun on a temporary charging parking space.

[0037] In this embodiment, in response to the battery's protection mode being activated, after determining the battery's current request information based on the current tag information and current battery level information, and in response to the battery receiving the current current corresponding to the current request information from the charging device, the current charging operation is performed on the battery using the current current. Optionally, based on determining the battery's current request information, this embodiment detects whether the battery has received the current current corresponding to the current request information from the charging device, and a second detection result can be obtained. If the second detection result indicates that the battery has received the current current corresponding to the current request information from the charging device, then the current charging operation is performed on the battery using the corresponding current current.

[0038] Optionally, if the second detection result indicates that the battery receives the current current corresponding to the current request information from the charging device, then the current charging operation is performed on the battery using the corresponding current current. For example, if the current charging operation is a slow charging operation at a fixed parking space, and the second detection result indicates that the battery receives the current current corresponding to the current request information from the charging gun at the fixed charging space, then the slow charging operation at the fixed parking space is performed on the battery using the corresponding current current.

[0039] Optionally, if the second detection result indicates that the battery receives the current current corresponding to the current request information from the charging device, then the current charging operation is performed on the battery using the corresponding current current. For example, if the current charging operation is a frequent fast charging operation en route, and the second detection result indicates that the battery receives the current current corresponding to the current request information from the charging gun at the temporary charging station, then the frequent fast charging operation is performed on the battery using the corresponding current current.

[0040] In steps S101 to S103 of this application, when charging the vehicle's battery, in response to the vehicle's battery being connected to the charging device, the current tag information corresponding to the vehicle and the current battery level information are obtained; in response to the battery's protection mode being activated, the battery's current request information is determined based on the current tag information and the current battery level information; in response to the battery receiving the current current corresponding to the current request information from the charging device, the current charging operation is performed on the battery using the current current. Because this embodiment of the invention detects whether the battery's protection mode is activated based on the obtained current tag information and current battery level information, if the protection mode is detected to be activated, the battery's current request information can be determined based on the obtained current tag information and current battery level information. That is, it can be determined that the charging device is requested to input the current current to the battery. Then, in response to the battery receiving the current current corresponding to the current request information from the charging device, the current charging operation is performed on the battery using the received current current. This achieves the purpose of actively adjusting the current during the charging process, thereby solving the technical problem of short battery life in vehicles and achieving the technical effect of extending the battery's lifespan.

[0041] The battery charging method of the vehicle described above in this embodiment will be further described below.

[0042] As an optional embodiment, the method further includes: obtaining historical charging information of the battery within a historical time period, wherein the historical charging information is used to represent the number of different historical charging operations performed by the battery within the historical time period, and any historical moment within the historical time period is earlier than the current moment; and determining the current tag information based on the historical charging information.

[0043] In this embodiment, the aforementioned historical charging information can be used to represent the number of different historical charging operations performed by the battery within a historical period, where any historical moment within the historical period is earlier than the current moment. The historical charging operations can include: slow charging operations performed on the battery at a fixed parking space within the historical period, and fast charging operations performed on the battery at a temporary parking space within the historical period. For example, a slow charging operation performed on the battery at a fixed parking space within the historical period can be a slow charging operation performed on the battery using alternating current at a fixed parking space within the historical period, or it can be a slow charging operation performed on the battery using a direct current of less than 200 amps (A) at a fixed parking space within the historical period. A fast charging operation performed on the battery at a temporary parking space within the historical period can be a fast charging operation performed on the battery using a direct current of greater than or equal to 200A at a temporary parking space within the historical period. This is merely an example and not a specific limitation.

[0044] In this embodiment, historical charging information of the battery within a historical time period is obtained. Optionally, this embodiment can download the historical charging information of the battery within a historical time period from a database stored in the cloud, or it can search for the historical charging information of the battery within a historical time period from a locally stored database.

[0045] In this embodiment, after acquiring the battery's historical charging information within a historical time period, the current tag information is determined based on the historical charging information. Optionally, based on the acquired historical charging information, this embodiment can determine first historical charging information and second historical charging information from the aforementioned historical charging information. The first historical charging information can be used to represent the total number of different historical charging operations, and the second historical charging information can be used to represent the number of historical charging operations. Based on the aforementioned first and second historical charging information, the current tag information can be determined, thereby achieving the goal of determining the type of current charging operation to be selected for the battery, and thus achieving the technical effect of improving the accuracy of the current tag information.

[0046] The following section further describes the steps of determining the current tag information based on historical charging information in this embodiment.

[0047] As an optional embodiment, determining the current tag information based on historical charging information includes: extracting first historical charging information and second historical charging information from the historical charging information, wherein the first historical charging information represents the total number of different historical charging operations, and the second historical charging information represents the number of historical charging operations; determining the quantitative relationship between the total number corresponding to the first historical charging information and a preset number, and determining the proportion of the number corresponding to the second historical charging information in the total number; determining the proportion relationship between the proportion and the preset proportion; and determining the current tag information based on the quantitative relationship and the proportion relationship.

[0048] In this embodiment, the aforementioned first historical charging information can be used to represent the total number of different historical charging operations. For example, the aforementioned first historical charging information can be represented by Charge_Count; this is merely an example and not a specific limitation.

[0049] In this embodiment, the aforementioned second historical charging information can be used to represent the number of historical charging operations. For example, the aforementioned second historical charging information can be represented by Charge_AC_Count, Charge_DC_S_Count, and Charge_DC_B_Count, which are only illustrative examples and are not specifically limited here.

[0050] In this embodiment, after acquiring the battery's historical charging information within a historical time period, first historical charging information and second historical charging information are extracted from the historical charging information. Optionally, based on the acquired historical charging information, this embodiment can extract information from the historical charging information according to the historical charging operations to obtain first historical charging information and second historical charging information.

[0051] Optionally, by dividing the aforementioned historical charging information according to historical charging operations, first historical charging information and second historical charging information can be obtained.

[0052] In this embodiment, the above-mentioned quantitative relationship can indicate that the total quantity is greater than or equal to a preset quantity, or it can indicate that the total quantity is less than a preset quantity. For example, the preset quantity can be, but is not limited to, 15, 16, and 17, etc. The values ​​here are only illustrative examples and are not specifically limited.

[0053] In this embodiment, the aforementioned proportion relationship can represent a proportion greater than or equal to a preset proportion, or it can represent a proportion less than a preset proportion. For example, the aforementioned proportion can be used as... This means that the above-mentioned preset percentage can be 80%. This value is only for illustrative purposes and is not a specific limitation.

[0054] In this embodiment, after extracting the first historical charging information and the second historical charging information from the historical charging information, the quantitative relationship between the total quantity corresponding to the first historical charging information and a preset quantity is determined, as well as the proportion of the quantity corresponding to the second historical charging information in the total quantity is determined. Optionally, based on the extracted first and second historical charging information, this embodiment compares the total quantity corresponding to the first historical charging information with the preset quantity to obtain the quantitative relationship between the total quantity corresponding to the first historical charging information and the preset quantity, and calculates the proportion of the quantity corresponding to the second historical charging information to the total quantity to obtain the proportion of the quantity corresponding to the second historical charging information in the total quantity.

[0055] In this embodiment, after determining the quantitative relationship between the total number corresponding to the first historical charging information and a preset number, and determining the proportion of the number corresponding to the second historical charging information in the total number, the proportion relationship between the proportion and the preset proportion is determined; based on the quantitative relationship and the proportion relationship, the current tag information is determined. Optionally, this embodiment, based on determining the quantitative relationship and the proportion, compares the determined proportion with the preset proportion to obtain the proportion relationship between the proportion and the preset proportion, and then determines the current tag information according to the above quantitative relationship and proportion relationship. This achieves the purpose of determining the type of current charging operation to be selected for the battery, thereby achieving the technical effect of improving the accuracy of the current tag information.

[0056] The following section further describes the steps of determining the current label information based on the quantitative and proportional relationships described in this embodiment.

[0057] As an optional embodiment, determining the current tag information based on quantity and proportion relationships includes: in response to the quantity relationship indicating that the total quantity is greater than or equal to a preset quantity, and the proportion relationship indicating that the proportion is greater than or equal to a preset proportion, determining target historical tag information from different historical tag information corresponding to the vehicle, wherein the historical tag information is used to represent the type of historical charging operation selected by the battery, and the number of historical charging operations of the type corresponding to the target historical tag information is greater than the number of historical charging operations of the type corresponding to the historical tag information other than the target historical tag information in the different historical tag information; and determining the target historical tag information as the current tag information.

[0058] In this embodiment, the aforementioned historical tag information can be used to indicate the type of historical charging operation that the battery has selected.

[0059] In this embodiment, the number of historical charging operations corresponding to the type of the target historical tag information is greater than the number of historical charging operations corresponding to the type of historical tag information other than the target historical tag information in different historical tag information.

[0060] In this embodiment, after determining the ratio relationship between the percentage and the preset percentage, in response to the quantity relationship indicating that the total quantity is greater than or equal to the preset quantity, and the ratio relationship indicating that the percentage is greater than or equal to the preset percentage, the target historical tag information is determined from the different historical tag information corresponding to the vehicle; and the target historical tag information is determined as the current tag information.

[0061] Optionally, in this embodiment, based on determining the quantity relationship and the proportion relationship, if the quantity relationship indicates that the total quantity is greater than or equal to a preset quantity, and the proportion relationship indicates that the proportion is greater than or equal to a preset proportion, then the second historical charging information corresponding to the proportion greater than or equal to the preset proportion is determined, and the historical charging operation corresponding to the second historical charging information corresponding to the proportion is determined as the target historical charging operation. Then, from the different historical tag information corresponding to the vehicle, the historical tag information indicating the type of the target historical charging operation is determined as the target historical tag information, and the determined target historical tag information is determined as the current tag information. This achieves the purpose of determining the type of current charging operation to be selected for the battery, thereby achieving the technical effect of improving the accuracy of the current tag information.

[0062] The following describes in further detail the steps of determining the battery current request information based on the current tag information and the current battery level information in response to the battery protection mode being activated in this embodiment.

[0063] As an optional embodiment, step S102, in response to the battery protection mode being activated, determines the battery current request information based on the current tag information and the current power information, including: in response to the protection mode being activated and the current power information meeting preset power information, performing a lookup in the current request library on the current tag information and the current power information to obtain the lookup result, wherein the current request library includes the mapping relationship between the tag information corresponding to different vehicles, the power information of different batteries, and different current request information; in response to the lookup result being successful in the current request library on the current tag information and the current power information, obtaining the current request information that meets the mapping relationship with the current tag information and the current power information.

[0064] In this embodiment, the aforementioned current request library may include: tag information corresponding to different vehicles, and the mapping relationship between the power information of different batteries and different current request information.

[0065] In this embodiment, the aforementioned preset battery level information can be used to reflect whether the current battery level is less than a preset battery level. For example, the preset battery level can be, but is not limited to, 92%. The value here is only for illustrative purposes and is not intended to be specific.

[0066] In this embodiment, the lookup result can be used to reflect whether the lookup of the current tag information and current power information in the current request library was successful. For example, the lookup result can indicate that the lookup of the current tag information and current power information in the current request library was successful, or it can indicate that the lookup of the current tag information and current power information in the current request library failed.

[0067] In this embodiment, after obtaining the vehicle's current tag information and the battery's current charge information in response to the vehicle's battery being connected to the charging equipment, and in response to the protection mode being activated and the current charge information meeting preset charge information, a lookup table is performed in the current request library to obtain the lookup result. Optionally, based on obtaining the current tag information and current charge information, this embodiment detects whether the battery's protection mode is activated to obtain a first detection result, and judges whether the current charge information meets preset charge information to obtain a judgment result. If the first detection result indicates that the protection mode is activated, and the judgment result indicates that the current charge information meets preset charge information, then a lookup table is performed in the current request library to obtain the lookup result.

[0068] In this embodiment, in response to the protection mode being activated and the current power information meeting the preset power information, a lookup table is performed on the current tag information and the current power information in the current request library. After obtaining the lookup result, in response to the lookup result indicating a successful lookup of the current tag information and the current power information in the current request library, current request information that satisfies the mapping relationship with the current tag information and the current power information is obtained. Optionally, based on the obtained lookup result, this embodiment performs result parsing. If the parsing result indicates a successful lookup of the current tag information and the current power information in the current request library, then the current request information that satisfies the mapping relationship with the current tag information and the current power information is used as the battery's current request information in the current request library. This achieves the goal of determining whether the charging device is requested to input the current current to the battery, thereby realizing the technical effect of dynamically adjusting the current current input from the charging device to the battery.

[0069] The battery charging method of the vehicle described above in this embodiment will be further described below.

[0070] As an optional embodiment, the method further includes: in response to the protection mode being activated and the current battery level not meeting the preset battery level information, outputting a prompt message, wherein the prompt message is used to indicate whether to start the current charging operation on the battery.

[0071] In this embodiment, the aforementioned prompt information can be used to indicate whether to begin the current charging operation of the battery. For example, the prompt information can be displayed on the mobile terminal in any of the following forms: animation, video, and pop-up window, etc., wherein the mobile terminal can include: smartphones, smartwatches, and tablets, etc., which are only examples and are not specifically limited.

[0072] In this embodiment, in response to the protection mode being activated and the current battery level not meeting the preset battery level requirements, a prompt message is output. Optionally, this embodiment, based on the current tag information and current battery level information, detects whether the battery's protection mode is activated to obtain a first detection result, and judges whether the current battery level meets the preset battery level requirements to obtain a judgment result. If the first detection result indicates that the protection mode is activated, and the judgment result indicates that the current battery level does not meet the preset battery level requirements, a prompt message is output to the mobile terminal to display the prompt message, thereby achieving the purpose of prompting whether to start the current charging operation for the battery.

[0073] In this embodiment of the invention, when charging a vehicle's battery, in response to the vehicle's battery being connected to the charging device, the current tag information corresponding to the vehicle and the current battery level information are obtained; in response to the battery's protection mode being activated, the battery's current request information is determined based on the current tag information and the current battery level information; in response to the battery receiving the current current corresponding to the current request information from the charging device, the current charging operation is performed on the battery using the current current. Because this embodiment of the invention detects whether the battery's protection mode is activated based on the obtained current tag information and current battery level information, if the protection mode is detected to be activated, the battery's current request information can be determined based on the obtained current tag information and current battery level information. That is, it can be determined that the charging device is requested to input the current current to the battery. Then, in response to the battery receiving the current current corresponding to the current request information from the charging device, the current charging operation is performed on the battery using the received current current. This achieves the purpose of actively adjusting the current during the charging process, thereby solving the technical problem of short battery life in vehicles and achieving the technical effect of extending the battery's lifespan.

[0074] The technical solutions of the embodiments of the present invention will be illustrated below with reference to preferred embodiments.

[0075] Currently, with the increasing popularity of new energy vehicles, the frequency of use of charging equipment is also increasing. Existing methods for charging vehicles mainly include AC slow charging and DC fast charging. However, these two methods only provide abnormal protection for the battery during the charging process and cannot actively adjust the current during charging, thus leading to a short battery lifespan.

[0076] To address the aforementioned technical problems, this invention proposes a vehicle battery charging method. Based on the acquired current tag information and current battery level information, the method detects whether the battery's protection mode is activated. If the protection mode is activated, the method determines the battery's current request information based on the acquired current tag information and current battery level information. That is, it determines that the charging device is requesting the battery to input the current current. Then, in response to the battery receiving the current current corresponding to the current request information from the charging device, the method performs the current charging operation on the battery using the received current current. This achieves the goal of actively adjusting the current during the charging process, thereby solving the technical problem of short battery life in vehicles and ultimately extending the battery's lifespan.

[0077] In this embodiment, by implementing a vehicle battery protection method based on user habit recognition and battery health status, the battery performing the current charging operation can be protected. For example, Figure 2This is a flowchart of a vehicle battery protection method based on user habit recognition and battery health status according to an embodiment of the present invention, such as... Figure 2 As shown, the method may include the following steps: Step S201: The vehicle terminal collects relevant data on the vehicle's charging process.

[0078] In the technical solution provided in step S201 of the present invention, the relevant data of the charging process may include: charging status data, denoted as ChargeStatus, which represents the current charging status of the vehicle (e.g., idle state / charging state), and is enumerated data; charging mode data, denoted as ChargeState, which can be used to represent the current charging mode of the vehicle (e.g., AC charging / DC charging), and is enumerated data; charging current data, in amperes (A), denoted as Charge_Current, which can be used to represent the current charging current, and is double-precision floating-point data; charging gun connection status data, denoted as Charge_Connect_Status, which can be used to represent the current charging gun connection status of the vehicle (e.g., connected state / not connected state); and battery health status (State of Health, abbreviated as SOH) data, which can be used to represent the current health status of the battery, and is double-precision floating-point data.

[0079] After the vehicle-mounted terminal collects relevant data on the vehicle's charging process, step S202 is executed to upload the relevant data to the data processing platform.

[0080] After uploading the relevant data to the data processing platform, step S203 is executed to divide the charging segment according to the segmentation strategy.

[0081] In the technical solution provided by step S203 of the present invention, the ChargeStatus signal data is used as the segmentation condition for the charging segment. According to the data upload frequency, if ChargeStatus changes from an idle state to a charging state, it is determined that this is the start time of charging; if ChargeStatus changes from a charging state to an idle state, it is determined that this is the end time of charging. The period from the start time of charging to the end time of the first charging is divided into one charging segment.

[0082] After the charging segments are divided according to the segmentation strategy, step S204 is executed. The data processing platform collects usage data of user charging methods according to the segmentation strategy and analyzes user types.

[0083] In the technical solution provided by step S204 of the present invention, the usage data of the user charging method may include: recording the number of segments in which the user's ChargeState = "AC charging" in all charging segments as Charge_AC_Count; recording the number of segments in which the user's ChargeState = "DC charging" in all charging segments, and the charging current of each segment, i.e., Charge_Current, does not exceed 200A as Charge_DC_S_Count; recording the number of segments in which the user's ChargeState = "DC charging" in all charging segments, and the charging current of each segment, i.e., Charge_Current, exceeds 200A as Charge_DC_B_Count; and recording the total number of all user charging segments as Charge_Count.

[0084] In this embodiment, a new field, User Type, is defined, denoted as User_Type. The new field User Type is the user type in the charging scenario. For example, the user type can be a user who charges slowly in a fixed parking space, or a user who frequently charges fast while on the go.

[0085] Optionally, if If Charge_Count≥15, then the user is determined to be a fixed parking space slow charging user, that is, User_Type="fixed parking space slow charging user".

[0086] Optionally, if If Charge_Count≥15, then the user is determined to be a fixed parking space slow charging user, that is, User_Type="fixed parking space slow charging user".

[0087] Optionally, if If Charge_Count ≥ 15, then the user is determined to be a frequent fast-charging user on the go, that is, User_Type = "frequent fast-charging user on the go".

[0088] After the data processing platform collects user charging method usage data according to the segmentation strategy and analyzes user types, step S205 is executed, and the data processing platform returns the user type conclusion to the relevant vehicle controller.

[0089] After the data processing platform returns the user type conclusion to the vehicle-related controller, step S206 is executed. Based on the user type returned by the data processing platform and the charging gun connection signal status, the vehicle drives the actuator to work.

[0090] In the technical solution provided by step S206 of the present invention, when the battery control unit recognizes that Charge_Connect_Status has switched to the connection state, it reads the user type and the battery health status. If it reads User_Type = "Fixed parking space slow charging user" and the current state of charge (SOC) is ≥92%, no action is taken; if it reads User_Type = "Frequent fast charging user on the go" and the current charge is ≥95%, no action is taken; otherwise, the controller drives the relevant actuators to perform two actions simultaneously: drive the in-vehicle central control screen to pop up a pop-up window to ask the user whether to start the battery protection mode, and drive the charging application (App) to pop up a prompt message to ask the user whether to start the battery protection mode.

[0091] After the vehicle drives the actuator to work based on the user type returned by the data processing platform and the charging gun connection signal status, step S207 is executed. The battery control unit dynamically limits the requested current based on user feedback and battery health status.

[0092] In the technical solution provided in step S207 of the present invention, when the battery control unit communicates with the charging device, the current request sent by the battery control unit is defined as Charge_Current_Request. If the user selects to start the battery protection mode, the following operations are performed: If User_Type = "Fixed parking space slow charging user" and 88% ≤ current battery level < 92%, the maximum value of Charge_Current_Request is 300A, and the charging device can respond normally to the current request of the battery control unit; if User_Type = "Fixed parking space slow charging user" and 80% ≤ current battery level < 88%, the maximum value of Charge_Current_Request is 250A, and the charging device can respond normally to the current request of the battery control unit; if User_Type = "Fixed parking space slow charging user" and current battery level < 80%, the maximum value of Charge_Current_Request is 200A, and the charging device can respond normally to the current request of the battery control unit. If User_Type = "Frequent Fast Charging User on the Way" and 90% ≤ Current Battery Level < 95%, the maximum value of Charge_Current_Request is 300A, and the charging device can respond normally to the current request from the battery's control unit. If User_Type = "Frequent Fast Charging User on the Way" and 84% ≤ Current Battery Level < 90%, the maximum value of Charge_Current_Request is 250A, and the charging device can respond normally to the current request from the battery's control unit. If User_Type = "Frequent Fast Charging User on the Way" and Current Battery Level < 84%, the maximum value of Charge_Current_Request is 200A, and the charging device can respond normally to the current request from the battery's control unit.

[0093] Optionally, the aforementioned current request library may include a current request table, as shown in Table 1 below.

[0094] For example, if a vehicle has been charged a total of 16 times, the relevant data for these 16 charges is shown in Table 2 below.

[0095] Table 1 Current Request Table

[0096] Table 2. Relevant charging data

[0097] It can be seen from Table 2 above that The battery SOC is ≥80%, and Charge_Count=16≥15, User_Type=“Frequent fast charging user on the go”. Specifically, when a user receives a prompt asking whether to activate “Battery Protection Mode”, and selects to activate it, and the battery SOC is 80%, then under these circumstances, the current request information Charge_Current_Request sent by the battery control unit is determined based on the current current in Table 1 above.

[0098] In this embodiment, when charging the vehicle's battery, in response to the vehicle's battery being connected to the charging device, the current tag information corresponding to the vehicle and the current battery level information are obtained; in response to the battery's protection mode being activated, the battery's current request information is determined based on the current tag information and the current battery level information; in response to the battery receiving the current current corresponding to the current request information from the charging device, the current charging operation is performed on the battery using the current current. Because this embodiment detects whether the battery's protection mode is activated based on the obtained current tag information and current battery level information, if the protection mode is detected to be activated, the battery's current request information can be determined based on the obtained current tag information and current battery level information. That is, it can be determined that the charging device is requested to input the current current to the battery. Then, in response to the battery receiving the current current corresponding to the current request information from the charging device, the current charging operation is performed on the battery using the received current current. This achieves the purpose of actively adjusting the current during the charging process, thereby solving the technical problem of short battery life in vehicles and achieving the technical effect of extending the battery's lifespan.
