[0042] Overview

[0043] As described in the background art, through the interconnection of the vehicle and the home energy management system, the vehicle-home interconnection system can, while maximizing the satisfaction of the energy demands of the vehicle and home loads, achieve efficient utilization of energy and reduce electricity costs, and thus has been widely applied. Among them, the vehicle is an electric vehicle or a hybrid vehicle, a power battery is provided in the vehicle, and the home energy management system includes a photovoltaic power generation device, a energy storage battery, etc. In the vehicle-home interconnection system, the safe and effective operation of the battery (such as the power battery and the energy storage battery) is a key factor in ensuring the operation performance of the vehicle-home interconnection system. Therefore, the vehicle-home interconnection system has higher requirements for the safety of the battery.

[0044] Currently, in the vehicle-home interconnection system, usually a monitoring module for monitoring the safety state of the power battery is provided in the vehicle, and a monitoring module for monitoring the safety state of the energy storage battery is provided in the home energy management system. In the case of an abnormality in the monitoring module, it is difficult to achieve reliable monitoring of the safety state of the battery, thus unable to ensure the safe and effective operation of the battery, and further unable to ensure the operation performance of the vehicle-home interconnection system.

[0045] To solve the problem that it is difficult to reliably monitor the safety state of the battery in the vehicle-home interconnection system in the traditional method, in the technical solution of this application, a battery safety monitoring system is provided. The battery safety monitoring system includes a first monitoring module, a second monitoring module, and a joint monitoring module. One of the first monitoring module and the second monitoring module is set in the vehicle, and the other is set in the home energy management system. The first monitoring module is used to identify the safety state of the target battery in the vehicle-home interconnection system to obtain the first state identification result of the target battery. The second monitoring module is used to identify the safety state of the target battery to obtain the second state identification result of the target battery. The joint monitoring module is used to control the operation of the first monitoring module and the second monitoring module, and is also used to determine the state identification result of the target battery based on the first state identification result and / or the second state identification result of the target battery, so that the safety state of the target battery can be flexibly identified through the first monitoring module and / or the second monitoring module according to the needs, and thus the reliable monitoring of the safety state of the target battery is realized.

[0046] Based on the above inventive concept, the battery safety monitoring system provided by the embodiments of this specification will be described exemplarily below.

[0047] The embodiments of this specification provide a battery safety monitoring system and a vehicle-home interconnection system, which are applied to the vehicle-home interconnection system. The vehicle-home interconnection system includes a vehicle and a home energy management system. As Figure 1 shown, the battery safety monitoring system includes a first monitoring module 101, a second monitoring module 102, and a joint monitoring module 103. One of the first monitoring module 101 and the second monitoring module 102 is set in the vehicle, and the other is set in the home energy management system. The joint monitoring module 103 is electrically connected to the first monitoring module 101 and the second monitoring module 102 respectively.

[0048] The first monitoring module 101 is used to identify the safety state of the target battery in the vehicle-home interconnection system to obtain the first state identification result of the target battery;

[0049] The second monitoring module 102 is used to identify the safety state of the target battery to obtain the second state identification result of the target battery;

[0050] The joint monitoring module 103 is used to control the operation of the first monitoring module 101 and the second monitoring module 102, and is also used to determine the state identification result of the target battery based on the first state identification result and / or the second state identification result of the target battery.

[0051] Specifically, the target battery can be a power battery in a vehicle or an energy storage battery in a home energy management system. In implementation, among the first monitoring module 101 and the second monitoring module 102, one monitoring module is set in the vehicle and the other monitoring module is set in the home energy management system. The joint monitoring module 103 can be set in the vehicle, can also be set in the home energy management system, or can be set in other terminal devices, such as a cloud server, and can be specifically set according to actual requirements.

[0052] Among them, the first monitoring module 101 can be used to identify the safety state of the target battery to obtain the first state identification result of the target battery, and the first state identification result can be normal state or abnormal state. In implementation, the first monitoring module 101 can identify the safety state of the target battery based on the operation data of the target battery and the first state identification model. The operation data of the target battery can include the charge and discharge rate, remaining power, temperature, internal resistance, etc. of the target battery. Preferably, the first state identification model can adopt a deep learning model, such as a convolutional neural network model, a long short-term memory network model, a self-attention mechanism model, etc. It can be understood that the first state identification model can also adopt a function model, which can be specifically set according to actual requirements.

[0053] The second monitoring module 102 can also be used to identify the safety state of the target battery to obtain the second state identification result of the target battery, and the second state identification result can be normal state or abnormal state. In implementation, the second monitoring module 102 can identify the safety state of the target battery based on the operation data of the target battery and the second state identification model. Preferably, the second state identification model can adopt a deep learning model, such as a convolutional neural network model, a long short-term memory network model, a self-attention mechanism model, etc. It can be understood that the second state identification model can also adopt a function model. Among them, the second state identification model can be the same as or different from the first state identification model, and can be specifically set according to actual requirements.

[0054] The joint monitoring module 103 can be used to control the operation of the first monitoring module 101 and the second monitoring module 102. For example, it can control the operation of the first monitoring module 101 and the second monitoring module 102 based on some or all of the data such as the priorities, fault states, and safety state identification results of the target battery of the first monitoring module 101 and the second monitoring module 102, so as to realize the safety state identification of the target battery through the first monitoring module 101 and / or the second monitoring module 102.

[0055] In addition, the combined monitoring module 103 is further configured to determine the status recognition result of the target battery according to the first status recognition result output by the first monitoring module 101 and / or the second status recognition result output by the second monitoring module 102. The status recognition result of the target battery may be normal status or abnormal status. For example, in the case where only the first monitoring module 101 performs safety status recognition on the target battery, the status recognition result of the target battery can be determined based on the first status recognition result. In the case where only the second monitoring module 102 performs safety status recognition on the target battery, the status recognition result of the target battery can be determined based on the second status recognition result. In the case where both the first monitoring module 101 and the second monitoring module 102 perform safety status recognition on the target battery, the status recognition result of the target battery can be determined based on the first status recognition result and the second status recognition result.

[0056] It can be understood that when the status recognition result of the target battery is normal status, the safety monitoring of the target battery can be continuously performed, and the safety monitoring of the target battery can also be performed according to a predetermined monitoring cycle. When the status recognition result of the target battery is abnormal status, a control instruction can be generated according to a predetermined control strategy and sent to the vehicle and / or the home energy management system to ensure the safety of the vehicle-home interconnection system during operation. At the same time, an alarm message can also be generated and sent to a predetermined terminal. The predetermined terminal can be the central control console of the vehicle, the alarm device in the home energy management system, the cloud server, or mobile terminals such as mobile phones and tablets to remind the user to perform fault troubleshooting and equipment maintenance in time.

[0057] Thus, through the method of the embodiment of the present application, the safety status of the target battery can be flexibly recognized by the first monitoring module 101 and / or the second monitoring module 102 according to requirements, and then the reliable monitoring of the safety status of the target battery is realized.

[0058] In a feasible implementation manner, the combined monitoring module 103 is specifically configured to:

[0059] Control the first monitoring module 101 to run;

[0060] When the first status recognition result of the target battery indicates that the status of the target battery is normal, determine that the status recognition result of the target battery is normal status;

[0061] When the first status recognition result of the target battery indicates that the status of the target battery is abnormal, control the second monitoring module 102 to run, and determine the status recognition result of the target battery based on the first status recognition result and the second status recognition result of the target battery.

[0062] Specifically, the priority of the first monitoring module 101 for identifying the safety status of the target battery can be higher than that of the second monitoring module 102 for identifying the safety status of the target battery, so as to preferentially perform safety monitoring on the target battery through the first monitoring module 101, and the second monitoring module 102 is used to assist the first monitoring module 101 in performing safety monitoring on the target battery. For example, when the target battery is the power battery of a vehicle, the first monitoring module 101 can be set on the vehicle, and the second monitoring module 102 can be set in the home energy management system. When the target battery is the energy storage battery in the home energy management system, the first monitoring module 101 can be set in the home energy management system, and the second monitoring module 102 can be set on the vehicle.

[0063] In implementation, when it is not recognized that the first monitoring module 101 and the second monitoring module 102 have failed, the joint monitoring module 103 can first control the first monitoring module 101 to run, so as to identify the safety status of the target battery through the first monitoring module 101, and output the first status recognition result of the target battery to the joint monitoring module 103.

[0064] After receiving the first status recognition result of the target battery, the joint monitoring module 103 can further determine whether to control the second monitoring module 102 to run based on the first status recognition result.

[0065] Among them, when the first status recognition result indicates that the status of the target battery is normal, the joint monitoring module 103 can directly determine that the status recognition result of the target battery is normal.

[0066] When the first status recognition result indicates that the status of the target battery is abnormal, the joint monitoring module 103 can control the second monitoring module 102 to run, so as to simultaneously identify the safety status of the target battery through the first monitoring module 101 and the second monitoring module 102. The first monitoring module 101 and the second monitoring module 102 can respectively output the first status recognition result and the second status recognition result of the target battery to the joint monitoring module 103. At this time, the joint monitoring module 103 can determine the status recognition result of the target battery based on the first status recognition result and the second status recognition result.

[0067] For example, the joint monitoring module 103 can determine the status recognition result of the target battery based on the consistency determination result of the first status recognition result and the second status recognition result; in addition, the first monitoring module 101 can also generate the credibility of the first status recognition result, the second monitoring module 102 can also generate the credibility of the second status recognition result, and the joint monitoring module 103 can also use the recognition result with higher credibility among the first status recognition result and the second status recognition result as the status recognition result of the target battery.

[0068] It can be understood that when the credibility of the first status recognition result is lower than a predetermined credibility, the joint monitoring module 103 can also control the second monitoring module 102 to operate, so as to simultaneously identify the safety status of the target battery through the first monitoring module 101 and the second monitoring module 102, and when the credibility of the first status recognition result is higher than or equal to the predetermined credibility, determine the status recognition result of the target battery as the first status recognition result.

[0069] Thus, through the method of the embodiment of the present application, the reliability of the status recognition result of the target battery can be effectively ensured.

[0070] In a feasible implementation manner, the joint monitoring module 103 is specifically configured to:

[0071] Determine the status recognition result of the target battery based on the consistency determination result of the first status recognition result and the second status recognition result of the target battery.

[0072] Specifically, when simultaneously identifying the safety status of the target battery through the first monitoring module 101 and the second monitoring module 102, when the joint monitoring module 103 receives the first status recognition result and the second status recognition result of the target battery, it can determine the consistency of the first status recognition result and the second status recognition result, and determine the status recognition result of the target battery according to the consistency determination result of the first status recognition result and the second status recognition result.

[0073] For example, when the first status recognition result and the second status recognition result are consistent, the first status recognition result or the second status recognition result can be directly used as the status recognition result of the target battery; in addition, when the first status recognition result and the second status recognition result are inconsistent, the status monitoring inconsistency factors of the target battery can be further identified. The status monitoring inconsistency factors of the target battery can be the factors that cause the inconsistency between the first status recognition result and the second status recognition result, and the status recognition result of the target battery can be determined according to the status monitoring inconsistency factors of the target battery. It is also possible to use the recognition result with higher credibility among the first status recognition result and the second status recognition result as the status recognition result of the target battery based on the credibility of the first status recognition result and the credibility of the second status recognition result, so as to effectively ensure the reliability of the status recognition result of the target battery.

[0074] In a feasible implementation manner, the joint monitoring module 103 is specifically configured to:

[0075] When the first status recognition result and the second status recognition result of the target battery are consistent, determine the status recognition result of the target battery as a status anomaly;

[0076] In the case where the first state recognition result and the second state recognition result of the target battery are inconsistent, identify the factors causing the inconsistency in the state monitoring of the target battery, and determine the state recognition result of the target battery based on the factors causing the inconsistency in the state monitoring of the target battery.

[0077] Specifically, when the first state recognition result of the target battery indicates that the state of the target battery is abnormal and the second monitoring module 102 is controlled to operate, if the first state recognition result and the second state recognition result of the target battery are consistent, it can be directly determined that the state recognition result of the target battery is abnormal.

[0078] If the first state recognition result and the second state recognition result of the target battery are inconsistent, the factors causing the inconsistency in the state monitoring of the target battery can be further identified, and the state recognition result of the target battery can be determined based on the factors causing the inconsistency in the state monitoring of the target battery. Among them, the factors causing the inconsistency in the state monitoring of the target battery can be the factors that cause the first state recognition result and the second state recognition result to be inconsistent. For example, it can include a monitoring module failure. In addition, it can also include an error in the transmission of the operating data of the target battery. For example, when the target battery is a power battery, the operating data of the target battery can be transmitted from the vehicle to the home energy management system. When the target battery is an energy storage battery, the operating data of the target battery can be transmitted from the home energy management system to the vehicle. During the transmission process, an error in the transmission of the operating data of the target battery may occur due to factors such as network anomalies.

[0079] Among them, the monitoring module failure can include software and / or hardware anomalies of the monitoring module itself, and can also include a decrease in the recognition accuracy of the model (such as the first state recognition model or the second state recognition model) used in the monitoring module to identify the safety state of the target battery. During the process of identifying whether the monitoring module fails, the operating data of the first monitoring module 101 and the second monitoring module 102, such as the calculation speed and resource occupancy, can be obtained, and based on the operating data of the first monitoring module 101, it can be identified whether there are software and / or hardware anomalies in the first monitoring module 101, and based on the operating data of the second monitoring module 102, it can be identified whether there are software and / or hardware anomalies in the second monitoring module 102. At the same time, the operating data of the target battery can also be compared with the target attributes of the training sample set of the first state recognition model and the target attributes of the training sample set of the second state recognition model respectively, and according to the comparison results, it can be determined whether there are problems with the recognition accuracy of the first state recognition model and the second state recognition model. The target attributes of the training sample set can be the numerical ranges of various operating parameters in the training sample set. For any one of the first state recognition model and the second state recognition model, if the operating data of the target battery is significantly different from the target attributes of the training sample set of the model, it indicates that the model has a problem with low recognition accuracy.

[0080] In addition, during the process of identifying whether the operation data of the target battery is transmitted incorrectly, the operation data of the target battery input by the first monitoring module 101 during the process of outputting the first state identification result of the target battery and the operation data of the target battery input by the second monitoring module 102 during the process of outputting the second state identification result of the target battery can be obtained, and the two are compared. If the two are consistent, it indicates that the operation data transmission of the target battery is normal; if the two are inconsistent, it indicates that the operation data transmission of the target battery is abnormal.

[0081] Thus, during the process of determining the state identification result of the target battery based on the state monitoring inconsistency factors of the target battery, the first state identification result or the second state identification result of the target battery can be determined as the state identification result of the target battery based on the fault identification results of the first monitoring module 101 and the second monitoring module 102 and the transmission error identification result of the operation data of the target battery, thereby effectively ensuring the reliability of the state identification result of the target battery.

[0082] It can be understood that after determining the state monitoring inconsistency factors of the target battery, an alarm message can also be generated based on the state monitoring inconsistency factors to remind relevant personnel to perform fault troubleshooting and equipment maintenance in a timely manner, thereby achieving timely response to faults and improving the operation safety of the system.

[0083] In a feasible implementation manner, the joint monitoring module 103 is specifically configured to:

[0084] When the state monitoring inconsistency factor of the target battery represents a fault of the first monitoring module 101 or the second monitoring module 102, the state identification result output by the monitoring module that has not failed among the first monitoring module 101 and the second monitoring module 102 is used as the state identification result of the target battery.

[0085] Specifically, when the operation data transmission of the target battery is normal, if the state monitoring inconsistency factor of the target battery represents a fault of the first monitoring module 101 or the second monitoring module 102, the state identification result (such as the first state identification result or the second state identification result) output by the monitoring module that has not failed among the first monitoring module 101 and the second monitoring module 102 can be used as the state identification result of the target battery, thereby effectively ensuring the reliability of the state identification result of the target battery.

[0086] It can be understood that in the case of abnormal transmission of the operating data of the target battery, if neither the first monitoring module 101 nor the second monitoring module 102 fails, the recognition result (e.g., the first status recognition result or the second status recognition result) output by the monitoring module set at the target battery among the first monitoring module 101 and the second monitoring module 102 can be used as the status recognition result of the target battery. For example, when the target battery is a power battery, the monitoring module set at the target battery is the monitoring module set on the vehicle among the first monitoring module 101 and the second monitoring module 102; when the target battery is an energy storage battery, the monitoring module set at the target battery is the monitoring module set in the home energy management system among the first monitoring module 101 and the second monitoring module 102.

[0087] In the case of abnormal transmission of the operating data of the target battery, if the status monitoring inconsistency factor of the target battery indicates that the first monitoring module 101 or the second monitoring module 102 fails, at this time, the status recognition result of the target battery can be determined based on the monitoring module that fails among the first monitoring module 101 and the second monitoring module 102. For example, if the monitoring module that fails among the first monitoring module 101 and the second monitoring module 102 is the monitoring module set at the target battery, at this time, it indicates that both the first status recognition result and the second status recognition result of the target battery are inaccurate. If there is a standby monitoring sub-module set in the failed monitoring module, the standby monitoring sub-module can be controlled to operate to ensure the uninterrupted monitoring of the battery safety status; if there is no standby monitoring sub-module set in the failed monitoring module, the relevant equipment can be controlled according to a predetermined protection strategy to protect the target battery. If the monitoring module that fails among the first monitoring module 101 and the second monitoring module 102 is another monitoring module other than the monitoring module set at the target battery, the recognition result (e.g., the first status recognition result or the second status recognition result) output by the monitoring module set at the target battery can be used as the status recognition result of the target battery.

[0088] In addition, regardless of whether the operating data of the target battery is abnormally transmitted, in the case where both the first monitoring module 101 and the second monitoring module 102 fail, if there is a standby monitoring sub-module set in the first monitoring module 101 and the second monitoring module 102, the standby monitoring sub-module can be controlled to operate to ensure the uninterrupted monitoring of the battery safety status; if there is no standby monitoring sub-module set in the first monitoring module 101 and the second monitoring module 102, the relevant equipment can be controlled according to a predetermined protection strategy to protect the target battery.

[0089] In a feasible implementation manner, both the first monitoring module 101 and the second monitoring module 102 include a main monitoring sub-module and a standby monitoring sub-module that are redundantly set;

[0090] The combined monitoring module 103 is further configured to:

[0091] When the state monitoring inconsistency factor of the target battery indicates a failure of the first monitoring module 101 and / or the second monitoring module 102, control the operating states of the main monitoring sub-module and the standby monitoring sub-module in the target monitoring module to switch. The target monitoring module is the monitoring module that fails among the first monitoring module 101 and the second monitoring module 102.

[0092] Specifically, the first monitoring module 101 may include a main monitoring sub-module and a standby monitoring sub-module with redundant settings. The functions of the main monitoring sub-module and the standby monitoring sub-module are the same, and both are used to identify the safety state of the target battery to obtain the first state recognition result of the target battery. The priority of the main monitoring sub-module may be higher than that of the standby monitoring sub-module. That is, the standby monitoring sub-module is a redundant design of the main monitoring sub-module.

[0093] At the same time, the second monitoring module 102 may also include a main monitoring sub-module and a standby monitoring sub-module with redundant settings. The functions of the main monitoring sub-module and the standby monitoring sub-module are the same, and both are used to identify the safety state of the target battery to obtain the second state recognition result of the target battery. The priority of the main monitoring sub-module may be higher than that of the standby monitoring sub-module. That is, the standby monitoring sub-module is a redundant design of the main monitoring sub-module.

[0094] When the state monitoring inconsistency factor of the target battery indicates a failure of the first monitoring module 101 and / or the second monitoring module 102, the combined monitoring module 103 may also control the operating states of the main monitoring sub-module and the standby monitoring sub-module in the target monitoring module to switch. The target monitoring module is the monitoring module that fails among the first monitoring module 101 and the second monitoring module 102. Thus, during the process of monitoring the safety state of the target battery, the risk of a monitoring blank period can be effectively reduced, and then the reliable monitoring of the safety state of the target battery is realized.

[0095] In a feasible implementation manner, the combined monitoring module 103 is further configured to:

[0096] When both the main monitoring sub-module and the standby monitoring sub-module in the first monitoring module 101 fail, control the second monitoring module 102 to operate, and determine the state recognition result of the target battery based on the second state recognition result of the target battery;

[0097] And,

[0098] When both the main monitoring sub-module and the standby monitoring sub-module in the second monitoring module 102 fail, control the first monitoring module 101 to operate, and determine the status recognition result of the target battery based on the first status recognition result of the target battery.

[0099] Specifically, when both the main monitoring sub-module and the standby monitoring sub-module in the first monitoring module 101 fail, during the process of monitoring the safety status of the target battery, the combined monitoring module 103 can directly control the second monitoring module 102 to operate, and determine the status recognition result of the target battery based on the second status recognition result of the target battery.

[0100] Among them, during the process of controlling the second monitoring module 102 to operate, it is possible to determine whether there are faults in the main monitoring sub-module and the standby monitoring sub-module in the second monitoring module 102. For example, when neither of them has a fault, the main monitoring sub-module in the second monitoring module 102 can be controlled to operate, and based on the second status recognition result output by the main monitoring sub-module in the second monitoring module 102, the status recognition result of the target battery can be determined. For example, the second status recognition result output by the main monitoring sub-module in the second monitoring module 102 can be directly used as the status recognition result of the target battery. Also, when the second status recognition result output by the main monitoring sub-module in the second monitoring module 102 indicates that the status of the target battery is normal, the status recognition result of the target battery can be determined to be normal. And when the second status recognition result output by the main monitoring sub-module indicates that the status of the target battery is abnormal, the standby monitoring sub-module in the second monitoring module 102 can be controlled to operate, and based on the consistency between the second status recognition result output by the main monitoring sub-module and the second status recognition result output by the standby monitoring sub-module in the second monitoring module 102, the status recognition result of the target battery can be determined. In addition, when there is a fault in the main monitoring sub-module or the standby monitoring sub-module in the second monitoring module 102, the monitoring sub-module without a fault in the second monitoring module 102 can be controlled to operate, and the second status recognition result output by this monitoring sub-module without a fault can be used as the status recognition result of the target battery.

[0101] In addition, when both the main monitoring sub-module and the standby monitoring sub-module in the second monitoring module 102 fail, during the process of monitoring the safety status of the target battery, the combined monitoring module 103 can only control the first monitoring module 101 to operate, and determine the status recognition result of the target battery based on the first status recognition result of the target battery.

[0102] Among them, during the process of controlling the operation of the first monitoring module 101, it is possible to determine whether there are faults in the main monitoring sub-module and the standby monitoring sub-module in the first monitoring module 101. For example, when neither of them has a fault, the main monitoring sub-module in the first monitoring module 101 can be controlled to operate, and according to the first status recognition result output by the main monitoring sub-module in the first monitoring module 101, the status recognition result of the target battery can be determined. For example, the first status recognition result output by the main monitoring sub-module in the first monitoring module 101 can be directly used as the status recognition result of the target battery. It is also possible to determine that the status recognition result of the target battery is normal when the first status recognition result output by the main monitoring sub-module in the first monitoring module 101 indicates that the status of the target battery is normal. In addition, when the first status recognition result output by the main monitoring sub-module indicates that the status of the target battery is abnormal, the standby monitoring sub-module in the first monitoring module 101 is controlled to operate, and according to the consistency between the first status recognition result output by the main monitoring sub-module in the first monitoring module 101 and the first status recognition result output by the standby monitoring sub-module, the status recognition result of the target battery is determined. In addition, when there is a fault in the main monitoring sub-module or the standby monitoring sub-module in the first monitoring module 101, the monitoring sub-module without a fault in the first monitoring module 101 can be controlled to operate, and the first status recognition result output by the monitoring sub-module without a fault is used as the status recognition result of the target battery.

[0103] Thus, through the method of the embodiment of the present application, during the process of monitoring the safety status of the target battery, automatic switching between the main monitoring sub-module and the standby monitoring sub-module can be realized without manual intervention, and the risk of monitoring blank period is effectively reduced, thereby realizing reliable monitoring of the safety status of the target battery.

[0104] In a feasible implementation manner, the operation priority of the main monitoring sub-module is higher than that of the standby monitoring sub-module;

[0105] The standby monitoring sub-module is used to monitor the operation status of the main monitoring sub-module during the operation of the main monitoring sub-module, and perform safety status recognition on the target battery when the operation status of the main monitoring sub-module is abnormal.

[0106] Specifically, for any one of the first monitoring module 101 and the second monitoring module 102, the operating priority of the main monitoring sub-module in the monitoring module is higher than that of the standby monitoring sub-module in the monitoring module. Among them, when the monitoring module is started, the standby monitoring sub-module in the monitoring module starts synchronously with the main monitoring sub-module and enters the hot standby state, establishing a heartbeat communication mechanism with the main monitoring sub-module in the monitoring module to monitor the operating state of the main monitoring sub-module in real time, and taking over the work of the main monitoring sub-module when the operating state of the main monitoring sub-module is abnormal, and identifying the health state of the target battery, so as to realize the automatic switching between the main monitoring sub-module and the standby monitoring sub-module, and further improve the reliability of the safety state identification result of the target battery.

[0107] In a feasible implementation manner, as Figure 2 shown, it further includes a data acquisition module 201, a first communication module 202, and a second communication module 203. One of the first communication module 202 and the second communication module 203 is arranged on the vehicle, and the other is arranged on the home energy management system;

[0108] The data acquisition module 201 is configured to acquire the operating data of the target battery and synchronously send the operating data of the target battery to a preset monitoring module through a first communication mode and a second communication mode. The preset monitoring module is the monitoring module arranged at the target battery among the first monitoring module 101 and the second monitoring module 102;

[0109] The first communication module 202 and the second communication module 203 are used for data transmission between the vehicle and the home energy management system;

[0110] The first monitoring module 101 and the second monitoring module 102 are used to identify the safety state of the target battery based on the operating data of the target battery.

[0111] Specifically, the battery safety monitoring system further includes a data acquisition module 201 to acquire the operating data of the target battery through the data acquisition module 201. Among them, the first monitoring module 101 and the second monitoring module 102 can identify the safety state of the target battery based on the operating data of the target battery to respectively output a first state identification result and a second state identification result of the target battery.

[0112] In addition, the battery safety monitoring system may further include a first communication module 202 and a second communication module 203. Among the first communication module 202 and the second communication module 203, one communication module is disposed in the vehicle, and the other communication module is disposed in the home energy management system. Thus, the vehicle and the home energy management system can perform data transmission through the first communication module 202 and the second communication module 203. For example, the transmitted data may include the operation data of the battery, the state identification result of the battery, control instructions, power demand data, etc. In addition, the vehicle and the home energy management system can also transmit data to terminal devices such as a cloud server through the corresponding communication modules to achieve remote monitoring and control of the vehicle and the home energy management system by the user, improving the user experience and the management flexibility of the vehicle-home interconnection system. It can be understood that the model parameters of the first state identification model and the second state identification model can also be dynamically optimized through the cloud server to continuously improve the adaptability of the battery safety monitoring system.

[0113] In implementation, the data acquisition module 201 can synchronously send the operation data of the target battery collected through the first communication mode and the second communication mode to a preset monitoring module. The preset monitoring module can be the monitoring module disposed at the target battery among the first monitoring module 101 and the second monitoring module 102. Figure 2 Taking the first monitoring module 101 as the monitoring module disposed at the target battery as an example; for example, when the target battery is a power battery, the monitoring module disposed at the target battery is the monitoring module disposed in the vehicle among the first monitoring module 101 and the second monitoring module 102. When the target battery is an energy storage battery, the monitoring module disposed at the target battery is the monitoring module disposed in the home energy management system among the first monitoring module 101 and the second monitoring module 102. Thus, the preset monitoring module can identify the safety state of the target battery according to the received operation data of the target battery.

[0114] Among them, the first communication mode and the second communication mode can be set according to actual needs. For example, the first communication mode can be a wired communication mode, and the second communication mode can be a wireless communication mode. In addition, the first communication mode and the second communication mode can also be different wireless communication modes or different wired communication modes respectively. Figure 2 Taking the first communication mode as a wired communication mode (such as the solid line in Figure 2 ), and the second communication mode as a wireless communication mode (such as the dashed line in Figure 2 ) as an example. It can be understood that the first communication mode can also be the same as the second communication mode.

[0115] In addition, the data acquisition module 201 can also synchronously send the operation data of the target battery collected through the first communication mode and the second communication mode to a preset communication module. The preset communication module can be the communication module set at the target battery among the first communication module 202 and the second communication module 203. Figure 2 The first communication module 202 is taken as an example of the communication module set at the target battery; for example, when the target battery is a power battery, the communication module set at the target battery is the communication module set on the vehicle among the first communication module 202 and the second communication module 203. When the target battery is an energy storage battery, the communication module set at the target battery is the communication module set in the home energy management system among the first communication module 202 and the second communication module 203. Through the preset communication module, the operation data of the target battery is sent to another communication module other than the preset communication module among the first communication module 202 and the second communication module 203. This another communication module can also synchronously transmit the received operation data of the target battery to the corresponding monitoring module through the first communication mode and the second communication mode, so that the monitoring module can identify the safety state of the target battery according to the received operation data of the target battery. Among them, the first communication module 202 and the second communication module 203 can also perform data transmission in parallel through two different wireless communication modes to further improve the reliability of data transmission.

[0116] Preferably, before the data acquisition module 201 sends the operation data of the target battery to the preset monitoring module and the preset communication module, it can also perform data preprocessing on the operation data of the target battery, such as filtering, calibration, outlier marking, etc., to improve the accuracy of the data and provide a data basis for improving the reliability of the state recognition result of the target battery.

[0117] Thus, through the dual data transmission mechanism in the embodiments of the present application, the risks such as data loss or mistransmission can be effectively reduced. Furthermore, during the process of the first monitoring module 101 and the second monitoring module 102 identifying the safety state of the target battery, the integrity of the operation data of the target battery can be effectively guaranteed, and the reliability of the safety state monitoring result of the target battery is further improved.

[0119] The technical features of the above embodiments can be combined arbitrarily.
