[0034] The following makes an explanation of exemplary embodiments of the present invention in conjunction with the accompanying drawings. Various details of the embodiments of the present invention are included to assist in understanding, and they should be considered merely exemplary. Therefore, those of ordinary skill in the art should recognize that various changes and modifications can be made to the embodiments described herein without departing from the scope and spirit of the present invention. Similarly, for the sake of clarity and conciseness, descriptions of well-known functions and structures are omitted in the following description.

[0035] It should be noted that, without conflict, the embodiments of the present invention and the technical features in the embodiments can be combined with each other.

[0036] In addition, the "first", "second", "third", etc. included in the terms of the embodiments of the present invention are used to distinguish similar objects, and do not necessarily describe a specific number or sequence. It should be understood that such terms can be interchanged under appropriate circumstances, which is only a way of distinguishing objects with the same attributes in the description of the embodiments of the present invention.

[0037] In addition, the vehicle involved in the embodiments of the present invention can be an internal combustion engine vehicle with an engine as a power source, a hybrid vehicle with an engine and an electric motor as power sources, an electric vehicle with an electric motor as a power source, etc.

[0038] Figure 1 It shows a schematic diagram of the main steps of the method for monitoring the state of a vehicle battery provided by the embodiments of the present invention:

[0039] Step S101: Receive the insulation resistance values of the vehicle battery at multiple moments sent by the vehicle.

[0040] Step S102: When it is determined that the values of the insulation resistance at multiple consecutive moments remain unchanged, send a data acquisition request to the vehicle to make the vehicle send the battery detailed state data of the vehicle battery.

[0041] Step S103: Analyze whether there is an abnormality in the state of the vehicle battery according to the detailed battery state data.

[0042] Specifically, the method for monitoring the state of the vehicle battery in steps S101 to S103 is applied to a server, such as a vehicle data platform, a vehicle data analysis server, etc.

[0043] The method for monitoring the state of the vehicle battery provided by the embodiment of the present invention first collects and monitors the insulation resistance values of the vehicle battery at multiple moments at a set time interval (for example, 30 seconds); when it is analyzed that the values of the insulation resistance values at multiple consecutive moments remain unchanged, further obtain the detailed battery state data of the vehicle battery, and then analyze and judge the abnormality for the detailed battery state data. It can be seen that the embodiment of the present invention overcomes the problem that the existing method has a long set interval and low real-time performance in monitoring the state of the vehicle battery, and the problem that reporting the detailed state information of the battery module each time results in a large amount of reported data and wastes resources. It improves the efficiency and real-time performance of monitoring the state of the vehicle battery and reduces the consumption of communication resources.

[0044] The range of the insulation resistance value of the vehicle battery pack is 0 kΩ to 60000 kΩ. Usually, the insulation resistance value collected at each set time interval (for example, 30 seconds) will change (for example, a change of a few ohms). Therefore, the embodiment of the present invention determines that the insulation resistance value of the vehicle battery has a data stagnation situation by judging whether the values of the insulation resistance values at multiple consecutive moments change.

[0045] Further, when the server receives the platform login data (the first login platform data login) of the vehicle, create a dynamic counting table, and use the dynamic counting table to record the vehicle unique identifier, such as the vehicle VIN (Vehicle Identification Number), the current insulation resistance value sent by the vehicle, the insulation resistance value sent at the previous moment, and the count initial value (the initial value is set to 0); use the dynamic counting table to execute the specific steps of judging whether the values of the insulation resistance values at multiple consecutive moments change. That is, generate a dynamic counting table for the vehicle; use the dynamic counting table to record the vehicle unique identifier of the vehicle, multiple insulation resistance values of the vehicle battery, and the count indicating the change situation of the insulation resistance value.

[0046] Further, use the dynamic count table to record the current insulation resistance value of a certain vehicle at each moment; further, subtract the insulation resistance value received at the previous moment (e.g., 30 seconds ago) from the most recently received insulation resistance value. If the subtraction result (i.e., the difference) is equal to 0, it indicates that the insulation resistance values at the two moments have not changed, and the count is incremented by 1. If the subtraction result (i.e., the difference) is not equal to 0, the count is not incremented and is reset to 0; and so on. For example, set the threshold to 4, that is, when the count reaches 4, it is determined that the insulation resistance values at multiple consecutive moments (e.g., 4 consecutive moments with each moment being 30 seconds) are unchanged, which indicates that there is a data stagnation situation in the insulation resistance value. That is, calculate the difference between the first insulation resistance value received at the current moment and the second insulation resistance value received at the previous moment adjacent to the current moment; in the case where it is determined that the difference is 0, increment by 1 the count used to indicate the change situation of the insulation resistance value, otherwise reset the count to 0; in the case where the value of the count obtained at multiple consecutive moments exceeds the set threshold, determine that the insulation resistance values at multiple consecutive moments are unchanged.

[0047] Further, after determining that the insulation resistance values at multiple consecutive moments are unchanged, execute the following method to determine the vehicle state:

[0048] The first method: Send a first instruction to the vehicle to indicate shortening the transmission time interval of the insulation resistance value; so that the vehicle, based on the first instruction, transmits the insulation resistance value of the vehicle battery according to the shortened transmission time interval; and determine whether the insulation resistance values at multiple consecutive moments change. Specifically, the server actively sends a first instruction to the vehicle (e.g., the in-vehicle communication terminal TBOX), causing the vehicle to shorten the time interval for transmitting the insulation resistance value, for example, from the original time interval of 30 seconds to 10 seconds, and then further transmit the insulation resistance value of the vehicle battery according to the shortened transmission time interval, and determine whether the insulation resistance values at multiple consecutive moments (with an interval of 10 seconds) change. Through this method, the refinement degree of monitoring the vehicle battery is further improved.

[0049] The second method: Send a second instruction to the in-vehicle communication terminal to collect the detailed battery status data of the battery module, causing the communication terminal to send a request for obtaining the detailed battery status data to the battery management system; receive various detailed battery status data of the vehicle battery obtained from the battery management system through the in-vehicle communication terminal.

[0050] Specifically, the server sends a second instruction to the vehicle communication terminal (vehicle TBOX terminal) to collect the detailed battery status data of the vehicle's battery module; and requests the TBOX to collect the current Ethernet communication signal data and send a handshake message to the battery management system (BMS); wherein, the detailed battery status data includes various data for indicating the operating status of the vehicle's battery, such as the number of batteries, the number of battery cells, the insulation resistance value, the total voltage, the total current, the voltage of a single battery cell, and the temperature of a single temperature pointer.

[0051] Further, analyzing whether there is an abnormality in the status of the vehicle's battery according to the detailed battery status data includes: for each type of detailed battery status data, obtaining the abnormal data threshold corresponding to the type of the detailed battery status data; and determining that there is an abnormality in the status of the vehicle's battery when it is determined that any one or more types of detailed battery status data exceed the corresponding abnormal data threshold. For example: for voltage and current, the highest or lowest thresholds are set, and if the threshold range is exceeded, it can be determined that there is an abnormality in the status of the vehicle's battery.

[0052] The third method: sending a third instruction to the vehicle communication terminal to collect the vehicle status data of the vehicle, so that the vehicle communication terminal sends a request for obtaining detailed battery status data to the vehicle control system; receiving the current vehicle status data of the vehicle obtained from the vehicle control system through the vehicle communication terminal; and analyzing whether there is an abnormality in the current vehicle status data.

[0053] Specifically, in the embodiments of the present invention, the vehicle status data of the vehicle can be further obtained, such as: the current position of the vehicle, the vehicle speed, the vehicle battery status data, etc. Further, through the current vehicle status data; and analyzing whether there is an abnormality in the current vehicle status data.

[0054] The fourth method: any one or more of the first method to the third method.

[0055] Further, for one or more of the following situations, send rescue information for the vehicle: the sending status of the data acquisition request indicates a failure; and / or, there is an abnormality in the status of the vehicle's battery; and / or, there is an abnormality in the current vehicle status data of the vehicle.

[0056] Specifically, when the server determines that there is an abnormality in the network (such as Ethernet, wireless network, etc.) with the vehicle communication terminal, resulting in the transmission status indication of the data acquisition request indicating a transmission failure, and / or determines that there is an abnormality in the state of the vehicle battery; and / or determines that there is an abnormality in the current vehicle status data of the vehicle, in any one or more of these abnormal situations, the vehicle situation is monitored in real time (continuing to shorten the time interval for receiving vehicle data, for example, the shortened time interval is 1 second), and rescue information is reported, for example: asking the rescue team to contact the vehicle owner to further confirm whether the vehicle has an abnormality, the specific abnormal information, etc.

[0057] The embodiment of the present invention improves the real-time performance and refinement degree of monitoring the vehicle battery state, and improves the safety and vehicle use experience of the vehicle user.

[0058] Figure 2 The main process schematic diagram showing the method for monitoring the vehicle battery state provided by the embodiment of the present invention can be applied is shown:

[0059] Step S201: Generate a dynamic count table for the vehicle; use the dynamic count table to record the vehicle unique identifier of the vehicle, multiple insulation resistance values of the vehicle battery, and the count indicating the change situation of the insulation resistance value.

[0060] Step S202: Calculate the difference between the first insulation resistance value received at the current moment and the second insulation resistance value received at the previous moment adjacent to the current moment.

[0061] Step S203: Determine whether the difference is 0. If so, execute step S204; otherwise, execute step S202 and reset the count to 0.

[0062] Step S204: Increment by 1 the count indicating the change situation of the insulation resistance value.

[0063] Step S205: When the value of the count obtained at multiple consecutive moments exceeds the set threshold, determine that the values of the insulation resistance values at multiple consecutive moments remain unchanged.

[0064] Step S206: Send a data acquisition request to the vehicle to cause the vehicle to send the battery detailed state data of the vehicle battery.

[0065] Step S207: Analyze whether there is an abnormality in the state of the vehicle battery according to the battery detailed state data.

[0066] The embodiments of the present invention overcome the problems that the existing method has a long set interval and low real-time performance in monitoring the battery state of a vehicle, and that reporting the detailed state information of the battery module each time results in a large amount of reported data and wastes resources. The real-time performance and efficiency of monitoring the battery state of the vehicle are improved, and the safety of the vehicle and the driving experience of the occupants are enhanced.
