Detailed Implementation

[0020] To enable those skilled in the art to better understand the present invention, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort should fall within the scope of protection of the present invention.

[0021] It should be noted that the terms "first," "second," etc., in the specification, claims, and accompanying drawings of this invention are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence. It should be understood that such data can be interchanged where appropriate so that the embodiments of the invention described herein can be implemented in orders other than those illustrated or described herein. Furthermore, the terms "comprising" and "having," and any variations thereof, are intended to cover a non-exclusive inclusion; for example, a process, method, system, product, or apparatus that comprises a series of steps or units is not necessarily limited to those steps or units explicitly listed, but may include other steps or units not explicitly listed or inherent to such processes, methods, products, or apparatus.

[0022] According to an embodiment of the present invention, a method for charging a vehicle battery is provided. It should be noted that the steps shown in the flowchart in the accompanying drawings can be executed in a computer system such as a set of computer-executable instructions. Furthermore, although a logical order is shown in the flowchart, in some cases, the steps shown or described may be executed in a different order than that shown here.

[0023] Figure 1 This is a flowchart of a vehicle battery charging method according to an embodiment of the present invention, such as... Figure 1 As shown, the method may include the following steps: Step S101: In response to the connection between the vehicle's battery and the charging device, the current tag information corresponding to the battery is obtained, wherein the current tag information is used to indicate the type of the current charging operation to be selected for the battery.

[0024] In the technical solution provided by step S101 of the present invention, the aforementioned current tag information can be used to indicate the type of current charging operation to be selected for the battery. For example, the aforementioned current charging operation may include: a slow charging operation performed on the battery in a fixed parking space (referred to as a fixed parking space slow charging operation), and a fast charging operation performed on the battery in a temporary parking space (referred to as a frequent fast charging operation on the go).

[0025] In this embodiment, the charging device can be a charging gun in a charging pile installed at the parking space.

[0026] In this embodiment, in response to the vehicle's battery and charging equipment being in a connected state, the current tag information corresponding to the battery is obtained. Optionally, this embodiment identifies the current state of the vehicle's battery and charging equipment; if the current state is identified as a connected state, the current tag information corresponding to the battery is obtained.

[0027] Optionally, if the current state is identified as a connected state, the current tag information corresponding to the battery is obtained. For example, if the current state is identified as a connected state, the current tag information can be determined based on the battery's historical charging information within a historical time period.

[0028] Optionally, the current tag information can be determined based on the battery's historical charging information within a historical period. For example, from the historical charging information, first historical charging information and second historical charging information are extracted, where 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; the quantitative relationship between the total number corresponding to the first historical charging information and a preset number is determined, and the proportion of the number corresponding to the second historical charging information in the total number is determined; 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.

[0029] Optionally, the current tag information is determined based on quantity and proportion relationships. For example, 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, target historical tag information is determined from different historical tag information corresponding to the vehicle. Here, the historical tag information is used to represent the type of historical charging operation selected for the battery. 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. The target historical tag information is then determined as the current tag information.

[0030] Step S102: Based on the current tag information, determine the activation result of the battery protection mode, wherein the protection mode is a mode used to protect the battery from performing safe charging operations, and the activation result is used to represent the relationship between the protection mode and the activation state of the protection mode.

[0031] In the technical solution provided by step S102 of the present invention, the protection mode can be a mode for protecting the battery during safe charging operations. For example, the protection mode can also be called a battery protection mode.

[0032] In this embodiment, the startup result can be used to represent the relationship between the protection mode and the startup state of the protection mode. For example, the startup result can indicate that the protection mode is in the startup state or that the protection mode is not in the startup state. This is only an example and is not a specific limitation.

[0033] In this embodiment, after acquiring the current tag information corresponding to the battery in response to the connection between the vehicle's battery and the charging equipment, the activation result of the battery's protection mode is determined based on the current tag information. Optionally, this embodiment can determine the activation result of the protection mode by comparing the current tag information with target tag information based on the acquired current tag information. The target tag information can be used to represent the type of charging operation selected for the battery. For example, the selected charging operation may include: slow charging performed on the battery in a fixed parking space, and fast charging performed on the battery in a temporary parking space.

[0034] Optionally, the activation result of the protection mode can be determined by comparing the current tag information with the target tag information. For example, by comparing the current tag information with the target tag information, the information relationship between the current tag information and the target tag information can be obtained, thereby determining the activation result of the protection mode.

[0035] Step S103: Based on the startup result, send the battery current request information to the charging device, wherein the current request information is used to request the charging device to input the current current to the battery.

[0036] In the technical solution provided by step S103 of the present invention, the current request information is used to request the charging device to input the current current to the battery. For example, the current request information can be represented by Charge_Current_Request.

[0037] In this embodiment, after determining the activation result of the battery's protection mode based on the current tag information, a current request message for the battery is sent to the charging device based on the activation result. Optionally, based on the determined activation result of the protection mode, if the activation result indicates that the protection mode is in an activated state, the current request message can be determined as information for requesting the charging device to input the current current corresponding to a fast charging operation for the battery, and the determined current request message can be sent to the charging device; if the activation result indicates that the protection mode is not in an activated state, the current request message can be determined as information for requesting the charging device to input the current current corresponding to a slow charging operation for the battery, and the determined current request message can be sent to the charging device.

[0038] Step S104: Obtain the current current sent by the charging device in response to the current request information, and perform the current charging operation on the battery using the current current.

[0039] In the technical solution provided by step S104 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.

[0040] In this embodiment, after sending a battery current request to the charging device based on the startup result, the current current sent by the charging device in response to the current request is obtained, and the current charging operation is performed on the battery using the current current. Optionally, this embodiment, based on sending the battery current request to the charging device, detects whether the battery has received the current current sent by the charging device in response to the current request, and obtains a detection result. If the detection result indicates that the battery has received the current current sent by the charging device in response to the current request, then the current charging operation is performed on the battery using the current current.

[0041] Optionally, if the detection result indicates that the battery receives the current current sent by the charging device in response to the current request information, then the current charging operation is performed on the battery using the current current. For example, if the current charging operation is a slow charging operation at a fixed parking space, and the detection result indicates that the battery receives the current current sent by the charging gun at the fixed charging space in response to the current request information, then the slow charging operation at the fixed parking space is performed on the battery using the current current.

[0042] Optionally, if the detection result indicates that the battery receives the current current sent by the charging device in response to the current request information, then the current charging operation is performed on the battery using the current current. For example, if the current charging operation is a frequent slow charging operation en route, and the detection result indicates that the battery receives the current current sent by the charging gun at the temporary charging station in response to the current request information, then the frequent slow charging operation en route is performed on the battery using the current current.

[0043] In steps S101 to S104 of this application, when charging the vehicle battery, in response to the connection between the vehicle battery and the charging device, the current tag information corresponding to the battery is obtained; based on the current tag information, the activation result of the battery protection mode is determined; based on the activation result, a current request information for the battery is sent to the charging device; the current current sent by the charging device in response to the current request information is obtained, and the current charging operation is performed on the battery using the current current. Since this embodiment of the invention detects whether the battery protection mode is in the activated state based on the obtained current tag information, if the activation state is detected, a current request information for the battery is sent to the charging device. That is, it can be determined that the current current requested by the charging device is the current current input 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 limiting the current value during the charging process to a safe current value, thereby solving the technical problem of short battery life in vehicles and achieving the technical effect of extending the battery life.

[0044] The steps for determining the activation result of the battery protection mode based on the current tag information in this embodiment will be further described below.

[0045] As an optional embodiment, step S102, based on the current tag information, determines the activation result of the battery protection mode, including: determining the information relationship between the current tag information and the target tag information, wherein the target tag information is used to represent the type of charging operation selected for the battery; and determining the activation result based on the information relationship.

[0046] In this embodiment, the target tag information can be used to indicate the type of charging operation selected for the battery. For example, the selected charging operation may include slow charging operation and fast charging operation.

[0047] In this embodiment, after obtaining the current tag information corresponding to the battery in response to the connection between the vehicle's battery and the charging equipment, the information relationship between the current tag information and the target tag information is determined; based on the information relationship, the start result is determined.

[0048] Optionally, based on the current tag information obtained, this embodiment compares the current tag information with the target tag information to obtain the information relationship between the current tag information and the target tag information. Then, based on the information relationship, the activation result of the protection mode can be determined, thereby achieving the purpose of determining the relationship between the protection mode and the activation state, and thus realizing the technical effect of improving the safety of battery charging.

[0049] The steps for determining the startup result based on information relationships in this embodiment will be further described below.

[0050] As an optional embodiment, the target tag information includes: first target tag information and second target tag information. The first target tag information is used to indicate the type of slow charging operation selected for the battery, and the second target tag information is used to indicate the type of fast charging operation selected for the battery. Determining the startup result based on the information relationship includes: in response to the information relationship being the same as the first target tag information, determining the startup result as the protection mode not being activated; and in response to the information relationship being the same as the second target tag information, determining the startup result based on the battery's protection information, wherein the protection information indicates whether the vehicle receives information from the vehicle's terminal device indicating whether the battery has activated the protection mode.

[0051] In this embodiment, the target label information may include: first target label information and second target label information.

[0052] In this embodiment, the aforementioned first target tag information can be used to indicate the type of slow charging operation selected for the battery. For example, the slow charging operation could be a slow charging operation performed on the battery at a fixed parking space.

[0053] In this embodiment, after determining the information relationship between the current tag information and the target tag information, in response to the information relationship being that the current tag information and the first target tag information are the same, the startup result is determined to be that the protection mode is not in the startup state. Optionally, based on obtaining the current tag information, by comparing the current tag information with the first target tag information and the second target tag information, the information relationship between the current tag information and the first target tag information and the second target tag information can be obtained. If the information relationship is that the current tag information and the first target tag information are the same, the startup result is determined to be that the protection mode is not in the startup state. This achieves the purpose of determining the relationship between the protection mode and the startup state, thereby realizing the technical effect of improving the safety during battery charging.

[0054] In this embodiment, the second target tag information can be used to indicate the type of fast charging operation selected for the battery. For example, the fast charging operation could be a fast charging operation performed on the battery in a temporary parking space.

[0055] In this embodiment, the aforementioned protection information can be used to indicate whether the vehicle receives information from its terminal device regarding whether it is in battery startup protection mode. For example, the terminal device can be the vehicle's central control device, or it can be a mobile device containing a charging application (App) that communicates with the central control device.

[0056] In this embodiment, after determining the information relationship between the current tag information and the target tag information, in response to the information relationship being the same as the second target tag information, a startup result is determined based on the battery protection information. Optionally, based on the obtained current tag information, by comparing the current tag information with the first target tag information and the second target tag information, the information relationship between the current tag information and the first and second target tag information can be obtained. If the information relationship is the same as the second target tag information, then a startup result is determined based on the battery protection information. This achieves the purpose of determining the relationship between the protection mode and the startup state, thereby realizing the technical effect of improving the safety of battery charging.

[0057] The following section further describes the steps of determining the startup result based on battery protection information, where the current tag information and the second target tag information are the same, in response to the above-mentioned embodiment.

[0058] As an optional embodiment, the protection information includes: first protection information and second protection information. The first protection information indicates that the vehicle receives information from the terminal device indicating a battery startup protection mode, and the second protection information indicates that the vehicle receives information from the terminal device indicating a non-battery startup protection mode.

For example, the first protection information can be used to indicate that the vehicle has received information from the central control device indicating a battery start-up protection mode, or the first protection information can also be used to indicate that the vehicle has received information from the mobile device indicating a battery start-up protection mode.

[0061] In this embodiment, after determining the information relationship between the current tag information and the target tag information, in response to the information relationship being that the current tag information and the second target tag information are the same, and the protection information is the first protection information, the activation result is determined to be that the protection mode is in the activated state. Optionally, based on obtaining the current tag information, the information relationship between the current tag information and the first and second target tag information can be obtained by comparing the current tag information with the first and second target tag information. If the information relationship is that the current tag information and the second target tag information are the same, then it is determined whether the battery protection information is the first protection information or the second protection information. If it is determined that the battery protection information is the first protection information, the activation result is determined to be that the protection mode is in the activated state. This achieves the purpose of determining the relationship between the protection mode and the activated state, thereby realizing the technical effect of improving the safety of battery charging.

[0062] In this embodiment, the second protection information can be used to indicate that the vehicle receives information from the terminal device that it is not in the battery startup protection mode. For example, the second protection information can be used to indicate that the vehicle receives information from the central control device that it is not in the battery startup protection mode, or the second protection information can also be used to indicate that the vehicle receives information from the mobile device that it is not in the battery startup protection mode.

[0063] In this embodiment, after determining the information relationship between the current tag information and the target tag information, in response to the information relationship being that the current tag information and the second target tag information are the same, and the protection information is the second protection information, the activation result is determined to be that the protection mode is not in the activated state. Optionally, based on obtaining the current tag information, the information relationship between the current tag information and the first and second target tag information can be obtained by comparing the current tag information with the first and second target tag information. If the information relationship is that the current tag information and the second target tag information are the same, then it is determined whether the battery protection information is the first protection information or the second protection information. If it is determined that the battery protection information is the second protection information, the activation result is determined to be that the protection mode is not in the activated state. This achieves the purpose of determining the relationship between the protection mode and the activation state, thereby realizing the technical effect of improving the safety of battery charging.

[0073] As an optional embodiment, step S104, obtaining the current current sent by the charging device in response to the current request information, and performing a current charging operation on the battery using the current current, includes: obtaining a first current current sent by the charging device in response to the first current request information, and performing a fast charging operation on the battery using the first current current; obtaining a second current current sent by the charging device in response to the second current request information, and performing a slow charging operation on the battery using the second current current.

[0074] In this embodiment, after sending a battery current request message to the charging device based on the startup result, the first current sent by the charging device in response to the first current request message is obtained, and a fast charging operation is performed on the battery using the first current current. Optionally, if the current request message sent to the charging device is a first current request message, the embodiment detects whether the battery has received the first current sent by the charging device in response to the first current request message, and a detection result can be obtained. If the detection result indicates that the battery has received the first current sent by the charging device in response to the first current request message, a fast charging operation is performed on the battery using the first current current. This achieves the goal of limiting the current value during the charging process to a safe current value, thereby extending the battery life of the vehicle.

[0075] In this embodiment, after sending a battery current request information to the charging device based on the startup result, the first current sent by the charging device in response to the first current request information is obtained, and a fast charging operation is performed on the battery using the first current current. Optionally, if the current request information sent to the charging device is a second current request information, the embodiment detects whether the battery has received a second current sent by the charging device in response to the second current request information, and a detection result can be obtained. If the detection result indicates that the battery has received a second current sent by the charging device in response to the second current request information, a slow charging operation is performed on the battery using the second current current. This achieves the goal of limiting the current value during the charging process to a safe current value, thereby extending the battery life of the vehicle.

[0076] In this embodiment of the invention, when charging a vehicle battery, in response to the connection between the vehicle battery and the charging device, the current tag information corresponding to the battery is obtained; based on the current tag information, the activation result of the battery's protection mode is determined; based on the activation result, a current request information for the battery is sent to the charging device; the current current sent by the charging device in response to the current request information is obtained, and the current charging operation is performed on the battery using the current current. Since this embodiment of the invention detects whether the battery's protection mode is activated based on the obtained current tag information, if the protection mode is detected to be activated, a current request information for the battery is sent to the charging device. That is, it can be determined that the current current requested by the charging device is the current current input 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 limiting the current value during the charging process to a safe current value, thereby solving the technical problem of short battery life in vehicles and achieving the technical effect of extending the battery's lifespan.

[0077] The technical solutions of the embodiments of the present invention will be illustrated below with reference to preferred embodiments.

[0078] 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, both of these methods only provide abnormal protection for the battery during the charging process, leading to a technical problem of short battery life.

[0079] To address the aforementioned technical problems, this invention proposes a vehicle battery charging method. Based on the current tag information, it detects whether the battery's protection mode is activated. If the protection mode is activated, it sends a battery current request to the charging device. That is, it determines that the request to the charging device is for the current current input to the battery. Then, in response to the battery receiving the current current corresponding to the current request from the charging device, it performs the current charging operation on the battery using the received current current. This achieves the goal of limiting the current value during charging to a safe current value, thereby solving the technical problem of short vehicle battery life and ultimately extending the battery's lifespan.

[0080] In this embodiment, by implementing a vehicle battery protection method based on user habit recognition, the battery performing the current charging operation can be protected. For example, Figure 2 This is a flowchart of a vehicle battery protection method based on user habit recognition 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.

[0081] In the technical solution provided by 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; and 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).

[0082] 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.

[0083] After uploading the relevant data to the data processing platform, step S203 is executed to divide the charging segment according to the segmentation strategy.

[0084] 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.

[0085] 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.

[0086] 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.

[0087] 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.

[0088] 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".

[0089] 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".

[0090] 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".

[0091] 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.

[0092] 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.

[0093] 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. If User_Type = "slow charging user in fixed parking space", no action is taken; if User_Type = "frequent fast charging user on the go", 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 App to pop up a prompt message to ask the user whether to start the battery protection mode.

[0094] 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, in which the battery control unit limits the charging current request value based on the user selection.

[0095] 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 maximum value of Charge_Current_Request is limited to 200A, and the charging device can respond normally to the current request of the battery control unit.

[0096] For example, if a vehicle has been charged a total of 16 times, the relevant data for these 16 charges is shown in Table 1 below.

[0097] Table 1. Relevant charging data

[0098] It can be seen from Table 1 above that ≥80%, and Charge_Count=16≥15, User_Type=“Frequent Fast Charging User in Transit”. When a user receives a prompt asking whether to activate “Battery Protection Mode” and selects to do so, under the current conditions, the current request information sent by the battery control unit is used to request the charging gun to send a charging current not exceeding 200A.

[0099] In this embodiment, when charging the vehicle's battery, in response to the connection between the vehicle's battery and the charging device, the current tag information corresponding to the battery is obtained; based on the current tag information, the activation result of the battery's protection mode is determined; based on the activation result, a current request information for the battery is sent to the charging device; the current current sent by the charging device in response to the current request information is obtained, and the current charging operation is performed on the battery using the current current. Since this embodiment detects whether the battery's protection mode is activated based on the obtained current tag information, if the protection mode is detected to be activated, a current request information for the battery is sent to the charging device. That is, it can be determined that the current current requested by the charging device is the current current input 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 limiting the current value during the charging process to a safe current value, thereby solving the technical problem of short battery life in vehicles and achieving the technical effect of extending the battery's lifespan.
