Description

Technical Field

[0001] This invention relates to the field of vehicle monitoring technology, and in particular to a method, device, and electronic device for monitoring the state of a power battery based on an on-board HMI. Background Technology

[0002] In existing technologies, the status monitoring and fault diagnosis of power batteries in new energy vehicles rely on external auxiliary tools, typically using PCs, CAN analyzers, and OBD devices for data collection and analysis. However, these testing tools are often patented, resulting in high procurement costs when usage is infrequent; they are also highly specialized, making them difficult for non-professionals to operate; furthermore, they are not included in the vehicle's accessory equipment list and are only provided by automakers, 4S stores, and repair shops. Therefore, when the power battery status needs to be checked in a vehicle, it is necessary to wait for professionals to arrive with the equipment, leading to long waiting times.

[0003] The above problems urgently need to be addressed. Summary of the Invention

[0004] The purpose of this invention is to at least partially solve one of the technical problems existing in the prior art.

[0005] Therefore, one objective of this invention is to provide a power battery status monitoring method based on an in-vehicle HMI. This method can achieve real-time monitoring of the power battery status without the need for external devices, thereby improving the real-time performance and convenience of dynamic battery status monitoring and enhancing the user's driving experience.

[0006] Another objective of this invention is to provide a power battery status monitoring device based on an in-vehicle HMI.

[0007] To achieve the above-mentioned technical objectives, the technical solutions adopted in the embodiments of the present invention include: On one hand, embodiments of the present invention provide a method for monitoring the state of a power battery based on an on-board HMI, comprising the following steps: In response to the operator's authentication operation on the vehicle HMI, the operator's permissions are determined, and the vehicle HMI is controlled to enter the battery status monitoring interface. In response to the operator's activation of the monitoring function on the battery status monitoring interface, a battery status request message is generated according to the operator's permissions, and the battery status request message is sent to the battery management system via the CAN network. The battery status response message returned by the battery management system is received through the CAN network, and the battery status monitoring interface is rendered according to the battery status response message. In response to a manual refresh operation by the operator on the battery status monitoring interface, or when a preset automatic refresh time interval is reached, the updated battery status request message is sent to the battery management system via the CAN network.

[0008] Furthermore, in one embodiment of the present invention, the step of determining the operator's permissions and controlling the vehicle HMI to enter the battery status monitoring interface in response to the operator's authentication operation on the vehicle HMI specifically includes: When the vehicle is parked, in response to the operator's multi-touch operation on the vehicle HMI, the vehicle HMI is controlled to enter the identity authentication interface. Obtain the user ID and verification information entered by the operator on the identity authentication interface, and perform initial identity authentication on the operator based on the user ID and the verification information; Once the initial identity authentication is successful, the authentication interface will prompt the operator to perform a preset button operation on the vehicle's electronic key. In response to the operator's preset button operation on the vehicle's electronic key, the system confirms successful identity authentication and determines the operator's permissions based on the user ID. The battery status monitoring interface with the corresponding permissions is determined according to the operator's permissions, and the vehicle HMI is controlled to enter the battery status monitoring interface.

[0009] Furthermore, in one embodiment of the present invention, the step of generating a battery status request message according to the operator's permissions and sending the battery status request message to the battery management system via the CAN network specifically includes: Based on the operator's permissions, determine the corresponding multiple battery status monitoring items, and generate the battery status request message based on the battery status monitoring items; The battery status request message is sent to the CAN gateway, which then forwards the battery status request message to the battery management system via the CAN network.

The numerical regions corresponding to each battery status monitoring item in the battery status monitoring interface are updated and rendered based on the real-time values. And / or, The change curves corresponding to each battery status monitoring item in the battery status monitoring interface are updated and rendered based on the real-time values.

[0012] Furthermore, in one embodiment of the present invention, the power battery state monitoring method further includes the following steps: In response to the operator's battery fault diagnosis operation on the vehicle HMI, the vehicle HMI is controlled to enter the battery fault diagnosis interface. In response to the operator's activation of the diagnostic function on the battery fault diagnosis interface, a fault diagnosis request message is generated according to the operator's permissions, and the fault diagnosis request message is sent to the battery management system via the CAN network. The fault diagnosis response message returned by the battery management system is received through the CAN network, and the battery fault diagnosis interface is rendered according to the fault diagnosis response message. In response to a manual refresh operation by the operator on the battery fault diagnosis interface, or when a preset automatic refresh time interval is reached, the updated fault diagnosis request message is sent to the battery management system via the CAN network.

[0013] Furthermore, in one embodiment of the present invention, rendering the battery fault diagnosis interface based on the fault diagnosis response message specifically includes: Based on the fault diagnosis response message, determine the occurrence time and first fault description of several newly added fault items, and / or determine the recovery time and second fault description of several historical fault items. The fault information of the newly added fault item is rendered in the fault item area of ​​the battery fault diagnosis interface according to the occurrence time and the first fault description, and / or the fault status of the historical fault item is modified in the fault item area of ​​the battery fault diagnosis interface according to the recovery time and the second fault description. Both the first fault description and the second fault description include the fault level, fault code, fault content, fault cause, and suggested countermeasures.

[0014] On the other hand, embodiments of the present invention provide a power battery state monitoring device based on an in-vehicle HMI, comprising: The identity authentication module is used to respond to the operator's identity authentication operation on the vehicle HMI, determine the operator's permissions, and control the vehicle HMI to enter the battery status monitoring interface.

The monitoring interface rendering module is used to receive the battery status response message returned by the battery management system through the CAN network, and to render the battery status monitoring interface according to the battery status response message. The battery status update module is used to respond to the operator's manual refresh operation on the battery status monitoring interface, or, when the preset automatic refresh time interval is reached, to send the updated battery status request message to the battery management system via the CAN network.

[0025] It should be noted that in various specific embodiments of the present invention, when processing data related to user identity or characteristics, such as user information, user behavior data, user historical data, and user location information, user permission or consent is obtained first. Furthermore, the collection, use, and processing of this data comply with relevant laws, regulations, and standards. In addition, when embodiments of the present invention require access to sensitive personal information of users, separate permission or consent from the user is obtained through pop-ups or redirection to a confirmation page. Only after obtaining the user's separate permission or consent is the necessary user-related data for the normal operation of the embodiments of the present invention acquired.

[0026] Reference Figure 1 This invention provides a method for monitoring the state of a power battery based on an on-board HMI, specifically including the following steps: S101. In response to the operator's authentication operation on the vehicle HMI, determine the operator's permissions and control the vehicle HMI to enter the battery status monitoring interface. S102. In response to the operator's activation of the monitoring function on the battery status monitoring interface, generate a battery status request message according to the operator's permissions, and send the battery status request message to the battery management system via the CAN network. S103. Receive the battery status response message returned by the battery management system through the CAN network, and render the battery status monitoring interface according to the battery status response message. S104. In response to the operator's manual refresh operation on the battery status monitoring interface, or when the preset automatic refresh time interval is reached, send the updated battery status request message to the battery management system via the CAN network.

[0027] Specifically, the embodiments of the present invention make full use of the vehicle's existing configuration such as the vehicle-mounted HMI, CAN network, and battery management system (BMS) to support the operator in establishing status detection communication with the battery management system through the vehicle-mounted HMI and viewing status data, which is different from the dedicated equipment detection schemes in the prior art.

[0028] In this embodiment of the invention, the vehicle-mounted HMI has the following functions: 1) Enable / disable the detection function; 2) Automatic data refresh cycle setting, manual refresh button; 3) Permission recognition and management, interface display and switching; 4) Send enable / refresh request messages and receive battery status data messages.

[0029] The visual status display interface includes a battery status monitoring interface (including information such as battery voltage, current, and temperature) and a battery fault diagnosis interface (including information such as fault level, fault content, possible causes, and corresponding measures).

[0030] In this embodiment of the invention, the battery management system has the following functions: 1) Receive battery status request messages and send battery status response messages; 2) Collect battery status data and associate the data with CAN messages.

[0031] The associated message data includes battery status information (total voltage, bus voltage, bus current, remaining energy, cell voltage, cell temperature, etc.) as well as fault codes and fault levels (which are more specific than the fault prompts displayed on the instrument panel).

[0032] Specifically, in this embodiment of the invention, a power battery status monitoring interface is integrated into the vehicle-mounted HMI (Human-Machine Interface). An authenticated operator can use this interface to determine whether to enable the battery status monitoring function. The battery management system responds to the battery status request message and sends the relevant battery status corresponding to the operator's permissions to the vehicle's CAN network via CAN message. After the vehicle-mounted HMI collects the corresponding CAN signal, it displays the power battery status to the operator in a visual manner.

[0033] It should be noted that when the battery status monitoring function is not enabled, the BMS will not update or send status message data in order to reduce the bus load rate; the message data can be updated automatically by setting the automatic refresh interval according to the operator's actual needs, or it can be manually refreshed by manual operation.

[0034] It can be recognized that the embodiments of the present invention utilize the vehicle-mounted HMI, CAN network and battery management system already included in the vehicle configuration to realize real-time monitoring of the power battery status. Without relying on external equipment or tools, the power battery status can be detected and viewed in real time through the vehicle-mounted HMI under safe vehicle conditions. There is no waiting time and no additional purchase cost, which improves the real-time performance and convenience of dynamic battery status monitoring, thereby improving the user's vehicle experience.

[0035] As a further optional implementation, in response to the operator's authentication operation on the vehicle HMI, the operator's permissions are determined, and the vehicle HMI is controlled to enter the battery status monitoring interface, which specifically includes: S1011. When the vehicle is in a parked state, in response to the operator's multi-touch operation on the vehicle HMI, control the vehicle HMI to enter the identity authentication interface. S1012. Obtain the user ID and verification information entered by the operator on the identity authentication interface, and perform initial identity authentication on the operator based on the user ID and verification information. S1013. When the identity authentication is successful for the first time, the operator will be prompted to perform preset button operations on the vehicle's electronic key through the identity authentication interface. S1014. Responding to the operator's preset button operation on the vehicle's electronic key, confirm successful identity authentication and determine the operator's permissions based on the user ID. S1015. Determine the battery status monitoring interface with the corresponding permissions based on the operator's permissions, and control the vehicle HMI to enter the battery status monitoring interface.

[0036] Specifically, when the in-vehicle HMI allows operation (e.g., when the vehicle is parked), the user enters the authentication interface via multi-point (two-point or more) touch to prevent accidental operation. After entering their user ID on the authentication interface, the user can complete authentication by using a mobile verification code or app dynamic password, along with performing a preset button operation on the vehicle's electronic key (e.g., simultaneously pressing the "lock" and "unlock" buttons). Based on the user ID and verification information entered by the user, the corresponding permission level and access content are determined, and the user is then directed to the corresponding battery status monitoring interface based on their permission level. The user permission levels are categorized as shown in Table 1 below.

[0037] Table 1

[0038] As a further optional implementation, a battery status request message is generated based on the operator's permissions, and the battery status request message is sent to the battery management system via the CAN network, specifically including: S1021. Determine multiple corresponding battery status monitoring items according to the operator's permissions, and generate a battery status request message according to the battery status monitoring items. S1022. Send the battery status request message to the CAN gateway, so that the CAN gateway forwards the battery status request message to the battery management system through the CAN network.

[0039] As an optional implementation, the operator's permissions can be one of user permissions, maintenance personnel permissions, and production personnel permissions, wherein: When the operator has user privileges, the battery status monitoring items include battery SOH, battery SOC, battery remaining energy, bus current, bus voltage, bus temperature, battery maximum temperature, battery minimum temperature, and battery average temperature. When the operator's permissions are those of a maintenance personnel, the battery status monitoring items include battery SOH, battery SOC, battery remaining energy, bus current, bus voltage, bus temperature, battery maximum temperature, battery minimum temperature, battery average temperature, insulation self-test status, insulation resistance, maximum voltage of individual cells, minimum voltage of individual cells, and the sum of voltages of individual cells. When the operator's permissions are those of a production personnel, the battery status monitoring items include battery SOH, battery SOC, battery remaining energy, bus current, bus voltage, bus temperature, battery maximum temperature, battery minimum temperature, battery average temperature, insulation self-test status, insulation resistance, maximum voltage of individual cells, minimum voltage of individual cells, total voltage of individual cells, battery internal resistance, self-discharge rate, and battery balance status.

[0040] Specifically, different operator permissions are pre-configured with corresponding battery status monitoring items to meet the battery status monitoring needs of different operators. The battery status monitoring items for operators with different permissions are shown in Table 2 below.

[0041] Table 2

[0042] As a further optional implementation, the battery status monitoring interface is rendered based on the battery status response message, specifically including: S1031. Determine the real-time values ​​of each battery status monitoring item based on the battery status response message. S1032. Update and render the numerical areas corresponding to each battery status monitoring item in the battery status monitoring interface based on real-time values. And / or, S1033. Update and render the change curves corresponding to each battery status monitoring item in the battery status monitoring interface based on real-time values.

[0043] like Figure 2The diagram shows a schematic of the battery status monitoring interface provided in an embodiment of the present invention. Real-time values ​​for each battery status monitoring item are determined based on the battery status response message. For battery status monitoring items that require displaying current values ​​(such as SOH, SOC, remaining battery energy, bus current, maximum battery temperature, minimum battery temperature, average battery temperature, total cell voltage, maximum cell voltage, and minimum cell voltage), the corresponding value areas are updated and rendered based on the real-time values. For battery status monitoring items that require displaying change curves (such as maximum battery temperature, minimum battery temperature, average battery temperature, total cell voltage, maximum cell voltage, and minimum cell voltage), the corresponding change curves are updated and rendered based on the real-time values.

[0044] As an optional implementation, the power battery state monitoring method further includes the following steps: S105. Responding to the operator's battery fault diagnosis operation on the vehicle HMI, and controlling the vehicle HMI to enter the battery fault diagnosis interface. S106. In response to the operator's operation of enabling the diagnostic function on the battery fault diagnosis interface, generate a fault diagnosis request message according to the operator's permissions, and send the fault diagnosis request message to the battery management system through the CAN network. S107. Receive the fault diagnosis response message returned by the battery management system through the CAN network, and render the battery fault diagnosis interface according to the fault diagnosis response message. S108. In response to the operator's manual refresh operation on the battery fault diagnosis interface, or when the preset automatic refresh time interval is reached, the updated fault diagnosis request message is sent to the battery management system via the CAN network.

[0045] Specifically, the operator can perform battery fault diagnosis on the vehicle HMI (after identity authentication is completed). At this time, the vehicle HMI enters the battery fault diagnosis interface, the battery management system responds to the fault diagnosis request message, and sends the relevant fault information corresponding to the operator's permissions to the vehicle's CAN network through CAN messages. After the vehicle HMI collects the corresponding CAN signal, it prompts the operator with the fault diagnosis results in a visual way.

[0046] In some optional embodiments, different operator permissions are pre-configured with corresponding fault items for different fault levels to accommodate the fault diagnosis needs of different operators. The fault items corresponding to operators with different permissions are shown in Table 3 below.

[0047] Table 3

[0048] As a further optional implementation, the battery fault diagnosis interface is rendered based on the fault diagnosis response message, specifically including: S1071. Based on the fault diagnosis response message, determine the occurrence time and first fault description of several newly added fault items, and / or determine the recovery time and second fault description of several historical fault items. S1072. Render the fault information of the newly added fault item in the fault item area of ​​the battery fault diagnosis interface according to the occurrence time and the first fault description, and / or modify the fault status of the historical fault item in the fault item area of ​​the battery fault diagnosis interface according to the recovery time and the second fault description. Both the first fault description and the second fault description include the fault level, fault code, fault content, fault cause, and suggested countermeasures.

[0049] Specifically, based on the fault diagnosis response message, the occurrence time and first fault description of several newly added fault items are determined, and / or, the recovery time and second fault description of several historical fault items are determined. For newly added fault items, their corresponding fault information is rendered in the fault item area of ​​the battery fault diagnosis interface according to the occurrence time and first fault description; for historical fault items, their fault status is modified in the fault item area of ​​the battery fault diagnosis interface according to the recovery time and second fault description.

In the diagram, blue text indicates fault items that have been recovered, and red text indicates current fault items.
