Description

Technical Field

[0001] The present invention relates to the field of automobile batteries, and in particular to a battery monitoring method, device and storage medium. Background Art

[0002] During the design and development of automobiles, the longest parking time and the maximum static current value are considered as one of the important factors in selecting battery capacity. However, in some special cases, the static current of the vehicle may exceed the design value due to the user's installation of electrical equipment, such as driving recorders, entertainment systems, surround view systems, etc. On the other hand, the design strategy of original parts may be imperfect, which may cause the vehicle to not sleep or wake up abnormally under special working conditions, continuously consume battery power, and cause power loss. This type of power loss phenomenon is accidental, and when troubleshooting the problem, it is necessary to constantly simulate the usage scenario for testing, which takes a long time, is difficult, and has low efficiency.

[0003] A low battery will cause the vehicle to fail to start. If no effective warning measures are provided, it will cause unnecessary trouble to the car owner. At present, the market mainly collects the battery voltage value through the vehicle terminal and determines whether the battery voltage value is lower than the preset fixed voltage threshold. When the battery voltage value is lower than the preset fixed voltage threshold, an early warning is pushed through an application or short message.

[0004] In addition, as the vehicle age increases and the mileage increases, the quality of the battery will also decrease, and the remaining life will become less and less, that is, the battery is aging. When the battery is seriously aged, it will cause the vehicle to be unable to start, the entertainment system to be unusable, and the anti-theft system to fail to authenticate, etc., affecting the user's normal car experience. Therefore, it is very important to judge the aging of the battery.

[0005] Ordinary users usually judge battery aging by the length of time the vehicle has been used (e.g. more than 5 years), mileage (e.g. more than 100,000 kilometers), and shorter and shorter battery drain time (e.g. from 1 month to 1 week). For 4S stores, the parameters saved by the battery controller can be read through a diagnostic instrument for analysis. Furthermore, the market mainly collects battery SOH (State of Health) through vehicle terminals, and determines whether the battery SOH is lower than the preset fixed SOH threshold. When the battery SOH is lower than the preset fixed SOH threshold, an early warning is pushed through an application or short message.

[0006] However, the inventors of the present application discovered during the research process that if the preset fixed voltage threshold or the preset fixed SOH threshold is set too high for a low battery or aged battery, it will lead to false alarms and cause unnecessary disturbance to the user. Conversely, if the preset fixed voltage threshold or the preset fixed SOH threshold is set too low, it will lead to late alarms. At this time, the vehicle battery is already low or aged, and the warning to the user has lost its meaning. Summary of the invention

[0040] The following is a specific embodiment of a battery status monitoring method using a server as an execution subject provided by an embodiment of the present invention, please refer to Figure 2 , Figure 2 It is a flowchart of the battery status monitoring method provided by the embodiment of the present invention. This specification provides the method operation steps described in the embodiment or flowchart, but may include more or fewer operation steps based on conventional or non-creative labor. The order of steps listed in the embodiment is only one way of executing the steps among many orders, and does not represent the only execution order. When executed in an actual device or equipment, the method can be executed in sequence or in parallel (for example, in a parallel processor or multi-threaded processing environment) according to the embodiment or the method shown in the drawings. Specifically, Figure 2 As shown, the method may include:

[0041] Step S201: receiving feedback information on the battery sent by a mobile terminal or a vehicle-mounted terminal, wherein the feedback information includes user feedback information;

[0042] In the embodiment of the present invention, the feedback information may also include ambient temperature information or geographical location information.

[0043] The user feedback information refers to the fault information of the battery fed back by the user, and the user feedback information may include low-power missed reporting information and low-power false reporting information. The user feedback information may also include the SOH during maintenance and the average SOH of batteries of the same vehicle model during maintenance. The SOH during maintenance refers to the SOH of the battery during maintenance, and the SOH during maintenance can be determined through the replacement record of the battery. The average SOH of batteries of the same vehicle model during maintenance refers to the average SOH determined based on the SOH of multiple batteries configured with the same vehicle model during maintenance. The average SOH of batteries of the same vehicle model during maintenance can be updated regularly, for example, once a month.

[0044] Step S203: determining the initial state parameter threshold of the battery;

[0045] In an embodiment of the present invention, the initial state parameter threshold is an initially preset state parameter threshold, and the initial state parameter threshold can be determined based on a preliminary statistical analysis of a charge and discharge test of the battery, and the initial state parameter threshold may include an initial voltage parameter threshold, an initial SOC (State of Charge) parameter threshold, an initial voltage difference parameter threshold, an initial SOC difference parameter threshold, an initial SOH parameter threshold, and an initial charging voltage change parameter threshold.

[0046] Step S205: adjusting the initial state parameter threshold based on the feedback information to determine a target state parameter threshold;

[0047] In an embodiment of the present invention, the target state parameter threshold is a target state parameter threshold adjusted based on the initial state parameter threshold based on the user feedback information, and the target state parameter threshold may include a target voltage parameter threshold, a target SOC parameter threshold, a target voltage difference parameter threshold, a target SOC difference parameter threshold, a target SOH parameter threshold and a target charging voltage change parameter threshold.

[0048] It can be understood that, since the user feedback information is dynamic, the target state parameter threshold is also dynamic.

[0049] Step S207: Determine whether a battery status warning is required based on the target status parameter threshold and the current battery status information, and send battery status warning information to the mobile terminal or the vehicle-mounted terminal when a warning is required.

[0050] In an embodiment of the present invention, the target state parameter threshold and the current battery state information are two values ​​that characterize the same battery state. Specifically, when the target state parameter threshold is the target voltage parameter threshold, the current battery state information refers to the current battery voltage; when the target state parameter threshold is the target SOC parameter threshold, the current battery state information refers to the current battery SOC; when the target state parameter threshold is the target voltage difference parameter threshold, the current battery state information refers to the current battery voltage difference; when the target state parameter threshold is the target SOC difference parameter threshold, the current battery state information refers to the current battery SOC difference; when the target state parameter threshold is the target SOH parameter threshold, the current battery state information refers to the current battery SOH; when the target state parameter threshold is the target charging voltage change parameter threshold, the current battery state information refers to the current battery charging voltage change.

[0051] The current battery voltage difference is the voltage V reported for the nth time. n The voltage V reported for the n+1th time n+1 The difference between the current battery voltage and the current battery voltage can be expressed as V n -V n+1 , the current battery SOC difference is the SOC reported for the nth time n The SOC reported for the n+1th time n+1 The difference between the current battery SOC and the SOC difference can be expressed as SOC n -SOC n+1 .

[0052] The time interval between the nth report and the (n+1)th report may be a fixed time, for example, the battery voltage and SOC are reported every 24 hours.

[0053] In some embodiments, the user feedback information may include low-power missed reporting information and low-power false reporting information, the initial state parameter threshold may include an initial voltage parameter threshold, the target state parameter threshold may include a target voltage parameter threshold, and the current battery state information may include a current battery voltage;

[0054] Accordingly, adjusting the initial state parameter threshold based on the feedback information to determine the target state parameter threshold may include:

[0055] Determine a first voltage adjustment value of the initial voltage parameter threshold based on the power failure missed reporting information, and determine a second voltage adjustment value of the initial voltage parameter threshold based on the power failure false reporting information;

[0056] The initial state parameter threshold is adjusted based on the following formula to determine the target voltage parameter threshold:

[0057] V=V0+K1×a-K2×b

[0058] Among them, V is the target voltage parameter threshold, V0 is the initial voltage parameter threshold, a is the first voltage adjustment value, K1 is the weight of the first adjustment value, b is the second voltage adjustment value, and K2 is the weight of the second adjustment value.

[0059] Correspondingly, judging whether a battery status warning is needed based on the target status parameter threshold and the current battery status information may include:

[0060] Determining whether the current battery voltage is less than or equal to the target voltage parameter threshold;

[0061] If so, it is determined that a battery status warning is required, and the battery status warning may specifically include a battery low power status warning.

[0062] In some embodiments, the user feedback information may include low-power missed reporting information and low-power false reporting information, the initial state parameter threshold may include an initial SOC parameter threshold, the target state parameter threshold may include a target SOC parameter threshold, and the current battery state information may include a current battery SOC;

[0063] Accordingly, adjusting the initial state parameter threshold based on the feedback information to determine the target state parameter threshold may include:

[0064] Determine a first SOC adjustment value of the initial SOC parameter threshold based on the power failure misreporting information, and determine a second SOC adjustment value of the initial SOC parameter threshold based on the power failure misreporting information;

[0065] The initial state parameter threshold is adjusted based on the following formula to determine the target SOC parameter threshold:

[0066] SOC=SOC0+K3×c-K4×d

[0067] Wherein, SOC is the target SOC parameter threshold, SOC0 is the initial SOC parameter threshold, c is the first SOC adjustment value, K3 is the weight of the first SOC adjustment value, d is the second SOC adjustment value, and K4 is the weight of the second SOC adjustment value;

[0068] Correspondingly, judging whether a battery status warning is needed based on the target status parameter threshold and the current battery status information may include:

[0069] Determining whether the current battery SOC is less than or equal to the target SOC parameter threshold;

[0070] If so, it is determined that a battery status warning is required, and the battery status warning may specifically include a battery low power status warning.

[0071] In some embodiments, considering the contingency of the user feedback information, that is, the user feedback information may be received once accidentally within a long period of time, and in this case, even if the initial state parameter threshold is not adjusted after receiving the user feedback information, it will not cause subsequent omissions or false alarms. For this situation, if the initial state parameter threshold is adjusted after receiving the user feedback information, the workload of adjustment will increase. In order to avoid this problem, before the step of adjusting the initial state parameter threshold based on the feedback information to determine the target state parameter threshold, the method may further include:

[0072] Counting the sum of the number of times the low-power missed reporting information is received and the number of times the low-power false reporting information is received;

[0073] When the sum of the number of times the low-power missed reporting information is received and the number of times the low-power false reporting information is received is greater than or equal to the preset number of times, the step of adjusting the initial state parameter threshold based on the feedback information to determine the target state parameter threshold is performed.

[0074] For example, when the sum of the number of times the low-power missed reporting information is received and the number of times the low-power false reporting information is received is greater than or equal to 100, the step of adjusting the initial state threshold is performed.

[0075] It should be noted that if a bicycle has been adjusted, it will not be adjusted again.

[0076] In some embodiments, the feedback information may further include ambient temperature information or geographic location information, the initial state parameter threshold may include an initial voltage difference parameter threshold and / or an initial SOC difference parameter threshold, the target state parameter threshold may include a target voltage difference parameter threshold or a target SOC difference parameter threshold, and the current battery state information may include a current battery voltage difference or a current battery SOC difference;

[0077] Accordingly, adjusting the initial state parameter threshold based on the feedback information to determine the target state parameter threshold may include:

[0078] Determine a voltage difference adjustment value of the initial voltage difference parameter threshold based on the ambient temperature information or the geographical location information;

[0079] Determine the sum of the initial voltage difference parameter threshold and the voltage difference adjustment value as the target voltage difference parameter threshold; or,

[0080] Determining an SOC difference adjustment value of the initial SOC difference parameter threshold based on the ambient temperature information or the geographical location information;

[0081] Determine the sum of the initial SOC difference parameter threshold and the SOC difference adjustment value as the target SOC difference parameter threshold;

[0082] Correspondingly, judging whether a battery status warning is needed based on the target status parameter threshold and the current battery status information may include:

[0083] Determining whether the current battery voltage difference is greater than or equal to the target voltage difference parameter threshold;

[0084] If yes, it is determined that a battery status warning is required, and the battery status warning may specifically include a battery low power status warning; or,

[0085] Determining whether the current battery SOC difference is greater than or equal to the target SOC difference parameter threshold;

[0086] If so, it is determined that a battery status warning is required, and the battery status warning may specifically include a battery low power status warning.

[0087] Among them, the voltage difference adjustment value and the SOC difference adjustment value can be obtained by looking up a table, which includes the correspondence between temperature, voltage difference adjustment value and SOC difference adjustment value. The table can be determined in advance through statistical analysis of battery charging and discharging tests at different temperatures.

[0088] For example, assuming that the initial voltage difference parameter threshold is 1V, and the initial SOC difference parameter threshold is 10%, when the temperature is higher than 30 degrees, by looking up the temperature range table, the corresponding voltage difference adjustment value and SOC difference adjustment value are 0.2V and 2% respectively, then the target voltage difference parameter threshold is 1.2V, and the target SOC difference parameter threshold is 12%.

[0089] It is understandable that when the temperature is too high, the discharge speed will be accelerated, and by increasing the target voltage difference parameter threshold and the target SOC difference parameter threshold, it is possible to prevent low power leakage.

[0090] In some embodiments, considering that a single factor may cause the battery low power state warning to be inaccurate, in order to improve the accuracy of the battery low power state warning, the feedback information may also include ambient temperature information or geographical location information, the initial state parameter threshold may include an initial voltage parameter threshold, an initial SOC parameter threshold, an initial voltage difference parameter threshold and an initial SOC difference parameter threshold, the target state parameter threshold may include a target voltage parameter threshold, a target SOC parameter threshold, a target voltage difference parameter threshold and a target SOC difference parameter threshold, and the current battery state information may include the current battery voltage, the current battery SOC, the current battery voltage difference and the current battery SOC difference;

[0091] Accordingly, adjusting the initial state parameter threshold based on the feedback information to determine the target state parameter threshold may include:

[0092] Adjusting the initial voltage parameter threshold based on the power shortage missed reporting information and the power shortage false reporting information to determine a target voltage parameter threshold;

[0093] Adjusting the initial SOC parameter threshold based on the power shortage missed reporting information and the power shortage false reporting information to determine a target SOC parameter threshold;

[0094] Adjusting the initial voltage difference parameter threshold based on the ambient temperature information or the geographical location information to determine a target voltage difference parameter threshold;

[0095] Adjusting the initial SOC difference parameter threshold based on the ambient temperature information or the geographical location information to determine a target SOC difference parameter threshold;

[0096] Correspondingly, judging whether a battery status warning is needed based on the target status parameter threshold and the current battery status information may include:

[0097] Determining whether the current battery voltage is less than or equal to the target voltage parameter threshold;

[0098] If yes, it is determined that a battery status warning is required, and the battery status warning may specifically include a battery low power status warning;

[0099] If not, a step of determining whether the current battery SOC is less than or equal to the target SOC parameter threshold may be further performed;

[0100] Determining whether the current battery SOC is less than or equal to the target SOC parameter threshold;

[0101] If yes, it is determined that a battery status warning is required, and the battery status warning may specifically include a battery low power status warning;

[0102] If not, a step of determining whether the current battery voltage difference is greater than or equal to the target voltage difference parameter threshold may be further performed;

[0103] Determining whether the current battery voltage difference is greater than or equal to the target voltage difference parameter threshold;

[0104] If yes, it is determined that a battery status warning is required, and the battery status warning may specifically include a battery low power status warning;

[0105] If not, a step of determining whether the current battery SOC difference is greater than or equal to the target SOC difference parameter threshold may be further performed;

[0106] If yes, it is determined that a battery status warning is required, and the battery status warning may specifically include a battery low power status warning;

[0107] If not, a step of determining whether the current vehicle is not in sleep mode for a long time may be further performed;

[0108] Determining whether the current vehicle is not in sleep mode for a long time;

[0109] If yes, it is determined that a battery status warning is required, and the battery status warning may specifically include a battery low power status warning;

[0110] If not, a step of determining whether the current of the current vehicle is abnormal after being in sleep mode may be further performed;

[0111] Determining whether the current of the current vehicle is abnormal after being in sleep mode;

[0112] If so, it is determined that a battery status warning is required, and the battery status warning may specifically include a battery low power status warning.

[0113] Among them, the method of determining the target voltage parameter threshold, the target SOC parameter threshold, the target voltage difference parameter threshold and the target SOC difference parameter threshold is as described above and will not be repeated here.

[0114] It should be noted that the above-mentioned multiple judgment conditions can be used independently or in combination in any manner. For example, two judgment conditions can be used in combination, such as only judging the current battery voltage and the current battery SOC.

[0115] In some embodiments, the user feedback information may include the SOH during maintenance and the average SOH of batteries of the same vehicle model during maintenance, the initial state parameter threshold may include an initial SOH parameter threshold, the target state parameter threshold may include a target SOH parameter threshold, and the current battery state information may include the current battery SOH;

[0116] Accordingly, adjusting the initial state parameter threshold based on the feedback information to determine the target state parameter threshold may include:

[0117] The initial SOH parameter threshold is adjusted based on the following formula to determine the target SOH parameter threshold:

[0118] X=X0+K5×(X1-X0)-K6×(X0-X2)

[0119] Wherein, X is the target SOH parameter threshold, X0 is the initial SOH parameter threshold, X1 is the SOH during maintenance, K5 is the weight of the difference between the SOH during maintenance and the initial SOH parameter threshold, X2 is the average SOH value of the same vehicle type battery during maintenance, and K6 is the weight of the difference between the initial SOH parameter threshold and the average SOH value of the same vehicle type battery during maintenance;

[0120] For example, the initial SOH parameter threshold of the battery of the current vehicle is 50%, the SOH of the battery of the current vehicle during maintenance is 60%, the weight of the difference between the SOH during maintenance and the initial SOH parameter threshold is 0.7, the average SOH value of batteries of the same model during maintenance is 45%, and the weight of the difference between the initial SOH parameter threshold and the average SOH value of batteries of the same model during maintenance is 0.3, then X=50%+0.7×(60%-50%)-0.3×(50%-45%), wherein K5 and K6 can be adjusted according to market data analysis.

[0121] Correspondingly, judging whether a battery status warning is needed based on the target status parameter threshold and the current battery status information may include:

[0122] Determine whether the current battery SOH is less than or equal to the target SOH parameter threshold;

[0123] If so, it is determined that a battery status warning is required, and the battery status warning may specifically include a battery aging status warning.

[0124] In some embodiments, the feedback information may further include ambient temperature information or geographic location information, the initial state parameter threshold may include an initial charging voltage change parameter threshold, the target state parameter threshold may include a target charging voltage change parameter threshold, and the current battery state information may include a current battery charging voltage change;

[0125] Accordingly, adjusting the initial state parameter threshold based on the feedback information to determine the target state parameter threshold may include:

[0126] Determine a charging voltage change adjustment value of the initial charging voltage change parameter threshold based on the ambient temperature information or the geographical location information;

[0127] Determine the sum of the initial charging voltage variation parameter threshold and the charging voltage variation adjustment value as the target charging voltage variation parameter threshold;

[0128] Correspondingly, judging whether a battery status warning is needed based on the target status parameter threshold and the current battery status information may include:

[0129] Determining whether the current battery charging voltage change is less than or equal to the target charging voltage change parameter threshold;

[0130] If so, it is determined that a battery status warning is required, and the battery status warning may specifically include a battery aging status warning.

[0131] Among them, the charging voltage change adjustment value can be obtained by looking up a table, which includes the correspondence between temperature and charging voltage change adjustment value. The table can be determined in advance through statistical analysis of battery charging and discharging tests at different temperatures. The current battery charging voltage change refers to the charging voltage change value within a certain period of time, for example, the voltage change after charging for half an hour.

[0132] For example, assuming that the initial charging voltage change parameter threshold is 1V, when the temperature is lower than -10 degrees, by looking up the temperature range table, the corresponding charging voltage change adjustment value is -0.2V, then the target voltage difference parameter threshold is 0.8V.

[0133] It is understandable that when the temperature is too low, the charging speed will slow down, and by lowering the target charging voltage change parameter threshold, aging false alarms can be prevented.

[0134] In some embodiments, considering that a single factor may cause the battery aging status warning to be inaccurate, in order to improve the accuracy of the battery aging status warning, the feedback information includes the SOH during maintenance, the average SOH of batteries of the same vehicle type during maintenance, and the ambient temperature information or geographic location information, the initial state parameter threshold may include the initial SOH parameter threshold and the initial charging voltage change parameter threshold, the target state parameter threshold may include the target SOH parameter threshold and the target charging voltage change parameter threshold, and the current battery state information may include the current battery SOH and the current battery charging voltage change;

[0135] Accordingly, adjusting the initial state parameter threshold based on the feedback information to determine the target state parameter threshold may include:

[0136] The initial SOH parameter threshold is adjusted based on the SOH during maintenance and the average SOH of the battery of the same vehicle type during maintenance to determine the target SOH parameter threshold;

[0137] adjusting the initial charging voltage variation parameter threshold based on the ambient temperature information or the geographic location information to determine the target charging voltage variation parameter threshold;

[0138] Correspondingly, judging whether a battery status warning is needed based on the target status parameter threshold and the current battery status information may include:

[0139] Determine whether the current battery SOH is less than or equal to the target SOH parameter threshold;

[0140] If yes, it is determined that a battery status warning is required, and the battery status warning may specifically include a battery aging status warning;

[0141] If not, it may also be performed to determine whether the current battery charging voltage change is less than or equal to the target charging voltage change parameter threshold;

[0142] If so, it is determined that a battery status warning is required, and the battery status warning may specifically include a battery aging status warning.

[0143] Among them, the method of determining the target SOH parameter threshold and the target charging voltage change parameter threshold is as described above and will not be repeated here.

[0144] It should be noted that the above-mentioned multiple judgment conditions can be used independently or in combination in any way. For example, the above-mentioned two judgment conditions can adjust the judgment order, such as first judging the current battery charging voltage change and then judging the current battery SOH.

[0145] Furthermore, the above data analysis can be achieved by the cooperation of the vehicle terminal and the server. The vertical analysis of the single data can be achieved in the vehicle terminal, and the horizontal analysis of the comprehensive data can be achieved in the server.

[0146] The following is a specific embodiment of the monitoring method provided by the embodiment of the present invention with the battery status monitoring system as the execution body, please refer to Figure 3 , Figure 3 It is a flowchart of the battery status monitoring method provided by the embodiment of the present invention. This specification provides the method operation steps described in the embodiment or flowchart, but may include more or fewer operation steps based on conventional or non-creative labor. The order of steps listed in the embodiment is only one way of executing the steps among many orders, and does not represent the only execution order. When executed in an actual device or equipment, the method can be executed in sequence or in parallel (for example, in a parallel processor or multi-threaded processing environment) according to the embodiment or the method shown in the drawings. Specifically, Figure 3 As shown, the method may include:

[0147] Step S301: The mobile terminal or the vehicle-mounted terminal sends feedback information on the battery to the server, wherein the feedback information includes user feedback information;

[0148] In an embodiment of the present invention, the feedback information may also include ambient temperature information or geographic location information, where the ambient temperature information refers to the temperature of the environment in which the battery or the current vehicle is located, and the geographic location information refers to the location information of the battery or the current vehicle. After receiving the geographic location information, the server can query the temperature or temperature range of the current vehicle's location through the server's database.

[0149] The user feedback information refers to the fault information of the battery fed back by the user, and the user feedback information may include low-power missed reporting information and low-power false reporting information. The user feedback information may also include the SOH during maintenance and the average SOH of batteries of the same vehicle model during maintenance. The SOH during maintenance refers to the SOH of the battery during maintenance, and the SOH during maintenance can be determined through the replacement record of the battery. The average SOH of batteries of the same vehicle model during maintenance refers to the average SOH determined based on the SOH of multiple batteries configured with the same vehicle model during maintenance. The average SOH of batteries of the same vehicle model during maintenance can be updated regularly, for example, once a month.

[0150] In actual applications, the vehicle-mounted terminal is responsible for collecting the battery status and related information, which can generally be transmitted through the CAN bus, or obtained through self-calculation by sensors integrated inside the vehicle-mounted terminal, and qualified data can be uploaded to a server, such as a cloud server, through data cleaning.

[0151] Step S303: The server determines the initial state parameter threshold of the battery;

[0152] In an embodiment of the present invention, the initial state parameter threshold is the initial preset state parameter threshold of the battery, and the initial state parameter threshold may include an initial voltage parameter threshold, an initial SOC parameter threshold, an initial voltage difference parameter threshold, an initial SOC difference parameter threshold, an initial SOH parameter threshold and an initial charging voltage change parameter threshold.

[0153] Specifically, the manner in which the server determines the initial state parameter threshold of the battery is consistent with the manner in which the server determines the initial state parameter threshold of the battery in the method with the server as the execution subject, and will not be repeated here.

[0154] Step S305: the server adjusts the initial state parameter threshold based on the feedback information to determine the target state parameter threshold;

[0155] In an embodiment of the present invention, the target state parameter threshold is a target state parameter threshold adjusted based on the initial state parameter threshold based on the user feedback information, and the target state parameter threshold may include a target voltage parameter threshold, a target SOC parameter threshold, a target voltage difference parameter threshold, a target SOC difference parameter threshold, a target SOH parameter threshold and a target charging voltage change parameter threshold.

[0156] It can be understood that, since the user feedback information is dynamic, the target state parameter threshold is also dynamic.

[0157] Specifically, the server adjusts the initial state parameter threshold based on the feedback information to determine the target state parameter threshold in a manner consistent with the manner in which the server in the method with the server as the execution subject adjusts the initial state parameter threshold based on the feedback information to determine the target state parameter threshold, which will not be repeated here.

[0158] Step S307: the vehicle terminal obtains the current battery status information of the battery;

[0159] In an embodiment of the present invention, the target state parameter threshold and the current battery state information are two values ​​that characterize the same battery state. For example, when the target state parameter threshold is the target voltage parameter threshold, the current battery state information refers to the current battery voltage; when the target state parameter threshold is the target SOC parameter threshold, the current battery state information refers to the current battery SOC; when the target state parameter threshold is the target voltage difference parameter threshold, the current battery state information refers to the current battery voltage difference; when the target state parameter threshold is the target SOC difference parameter threshold, the current battery state information refers to the current battery SOC difference; when the target state parameter threshold is the target SOH parameter threshold, the current battery state information refers to the current battery SOH; when the target state parameter threshold is the target charging voltage change parameter threshold, the current battery state information refers to the current battery charging voltage change.

[0160] Step S309: the vehicle terminal sends the current battery status information to the server;

[0161] Step S311: The server determines whether a battery status warning is needed based on the target status parameter threshold and the current battery status information, and sends battery status warning information to the mobile terminal or the vehicle-mounted terminal when a warning is needed.

[0162] In the embodiment of the present invention, the battery status warning includes a battery low power status warning and / or a battery aging status warning.

[0163] Specifically, the manner in which the server determines whether a battery status warning is needed based on the target status parameter threshold and the current battery status information is consistent with the manner in which the server in the method with the server as the execution body determines whether a battery status warning is needed based on the target status parameter threshold and the current battery status information, and will not be repeated here.

[0164] It can be seen from the embodiments of the battery status monitoring method provided by the present invention that by receiving feedback information about the battery sent by a mobile terminal or a vehicle-mounted terminal, the feedback information includes user feedback information, the initial status parameter threshold of the battery is determined, and the initial status parameter threshold is adjusted based on the feedback information to determine the target status parameter threshold, and whether a battery status warning is needed is judged based on the target status parameter threshold and the current battery status information, and when a warning is needed, the battery status warning information is sent to the mobile terminal or the vehicle-mounted terminal, so that the target status parameter threshold of the battery can be reasonably and dynamically set, thereby avoiding false alarms or missed alarms of battery faults and improving the accuracy of battery fault warnings.

[0165] The embodiment of the present invention also provides a battery status monitoring device, such as Figure 4 As shown, the device comprises:

[0169] The battery status warning module 440 is used to determine whether a battery status warning is needed based on the target status parameter threshold and the current battery status information, and send battery status warning information to the mobile terminal or the vehicle-mounted terminal when a warning is needed.

[0172] The above embodiments only express several implementation methods of the present invention, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the invention patent. It should be pointed out that, for those of ordinary skill in the art, several variations and improvements can be made without departing from the concept of the present invention, and these all belong to the protection scope of the present invention.
