Description

Technical Field

[0001] The present application relates to the technical field of electric equipment, and in particular to a method, device, battery, equipment and storage medium for processing insulation faults. Background Art

[0002] Insulation resistance monitoring is an important part of the high-voltage safety design of electric vehicles to ensure the safety of the vehicle. When the vehicle is charged, such as DC charging, the insulation resistance of the entire vehicle will be affected by the DC charging pile because the high-voltage platform of the vehicle is connected to the high-voltage power grid of the external power supply equipment. When an insulation fault occurs, the insulation fault needs to be handled in time. However, handling insulation faults while the vehicle is charging may affect the charging of the vehicle. Therefore, how to reduce the impact of insulation fault handling on charging is a technical problem that needs to be solved urgently in this field. Summary of the invention

[0003] In view of this, the purpose of the embodiments of the present application is to provide a method, device, battery, equipment and storage medium for processing insulation faults, which can reduce the impact of insulation fault processing on charging.

[0004] According to a first aspect of the present application, a method for processing an insulation fault is provided, comprising:

[0005] Conduct insulation fault detection during the charging process of electrical equipment;

[0006] In response to detecting an insulation fault, determining a corresponding fault location strategy according to a degree of the insulation fault indicated by the first detection result;

[0007] The insulation fault is located based on the fault location strategy, and the faulty device where the insulation fault occurs is determined.

[0008] In the above process, by setting corresponding fault location strategies for different insulation fault degrees, when insulation faults of different degrees occur in the electrical equipment during charging, fault location analysis can be flexibly performed according to the fault degree, thereby minimizing the impact of insulation fault handling on the charging process.

[0009] In some embodiments, the fault localization strategy is used to indicate a timing for performing fault localization.

[0010] In the above process, since fault location will affect the charging of electrical equipment, the impact on charging can be minimized by controlling the timing of fault location execution under different insulation fault degrees through the fault location strategy.

[0011] In some embodiments, determining a corresponding fault location strategy according to the insulation fault degree indicated by the first detection result includes:

[0012] If the first detection result indicates a first insulation fault degree, determining a corresponding first fault location strategy;

[0013] If the first detection result indicates a second insulation fault degree, determining a corresponding second fault location strategy;

[0014] The second insulation fault degree is higher than the first insulation fault degree.

[0015] In the above process, the degree of insulation fault is divided into two levels, which correspond to the first fault location strategy and the second fault location strategy respectively, so that when the electrical equipment has insulation faults of different degrees during charging, the fault location analysis can be flexibly performed according to the first fault degree and the second fault degree, thereby minimizing the impact of insulation fault processing on the charging process.

[0016] In some embodiments, the first fault location strategy is used to indicate that insulation fault detection is performed after charging is completed.

[0017] In the above process, if the insulation fault occurring during the charging process is the first insulation fault level, it means that the insulation fault is a general insulation fault. By postponing the fault location until after the charging is completed, the impact of the insulation fault processing on the charging can be minimized.

[0018] In some embodiments, the first fault location strategy is further used to instruct: reducing the current charging power so that the electrical device can be charged by direct current or alternating current.

[0019] In the above process, when fault location is postponed until charging is completed, charging safety is ensured by charging the electrical equipment at reduced power.

[0020] In some embodiments, the method further comprises:

[0021] During the charging process, a prompt message indicating that the charging time is extended is output.

[0022] In the above process, when the electric device is charged at reduced power, since the decrease in charging power will lead to an extension of charging time, a prompt message can be output to remind the user, such as the driver, that the charging time may be extended, thereby improving the user experience.

[0023] In some embodiments, locating the insulation fault based on the fault location strategy and determining the faulty device where the insulation fault occurs includes:

[0024] In response to the completion of charging of the electric device, controlling the disconnection of charging;

[0025] An insulation fault detection is performed on the electrical equipment, and the faulty equipment is determined according to the obtained second detection result.

[0026] In the above process, the charging connection is disconnected after charging is completed, so that the charging device no longer affects the insulation resistance. Therefore, the faulty device can be determined through insulation fault detection, thereby realizing fault location through insulation fault detection after charging is completed.

[0027] In some embodiments, the second fault location strategy is used to indicate: performing insulation fault detection after charging is terminated.

[0028] In the above process, if the insulation fault occurring during the charging process is the second insulation fault level, it means that the insulation fault is more serious. In response to detecting the insulation fault of the second insulation fault level, charging is stopped, and the fault is located through insulation fault detection to ensure the safety of electrical equipment, charging devices and users' lives and property.

[0029] In some embodiments, locating the insulation fault based on the fault location strategy includes:

[0030] Controlling the disconnection of charging connection and performing insulation fault detection on the electrical equipment;

[0031] The faulty device is determined according to the obtained third detection result.

[0032] In the above process, by immediately disconnecting the charging connection, the charging device no longer affects the insulation resistance. Therefore, the faulty device can be determined through insulation fault detection, thereby realizing fault location through insulation fault detection after charging is terminated.

[0033] In some embodiments, before obtaining the third detection result, the method further includes:

[0034] Outputs no insulation fault information.

[0035] In the above process, by delaying the output timing of the insulation fault information, it is possible to avoid causing panic among users and reducing the degree of trust in the electrical equipment among users.

[0036] In some embodiments, the method further comprises:

[0037] According to the type of the faulty equipment, a fault handling method for the electrical equipment is determined.

[0038] In the above process, regardless of whether the type of the faulty device is an electric device, various fault situations are dealt with by performing fault processing on the electric device.

[0039] In some embodiments, determining the fault handling of the electrical device according to the type of the faulty device includes:

[0040] If the type of the faulty device is a charging device, determining that the fault handling includes allowing the function of the electrical device to be used; wherein the charging device is used to provide electrical energy;

[0041] If the type of the faulty device is the electric device, determining that the fault processing includes restricting the electric device from using a target function.

[0042] In the above process, after distinguishing whether the faulty device comes from the electric device, different fault processing is performed on the electric device, thereby minimizing the impact on the use of the electric device.

[0043] In some embodiments, if the type of the faulty device is a charging device, and the insulation fault of the charging device is a second insulation fault level, the fault processing further includes:

[0044] Output a prompt message for replacing the charging device.

[0045] In the above process, after the electric device stops charging, the fault handling may further include outputting a prompt message for replacing the charging device to prompt the user to go to the next charging device to charge the electric device.

[0046] In some embodiments, the target function includes an operation function and a power connection function; if the type of the faulty device is the power-consuming device, determining that the fault processing includes limiting the use of the target function of the power-consuming device includes:

[0047] If the insulation fault of the electrical equipment is a first insulation fault degree, determining that the fault processing includes: limiting the operating parameter of the operating function to be not greater than a preset threshold;

[0048] If the insulation fault of the electrical equipment is a second insulation fault degree, determining that the fault processing includes: controlling the power supply connection to be in a disconnected state;

[0049] The second insulation fault degree is higher than the first insulation fault degree.

[0050] In the above process, according to the insulation faults of the electrical equipment of different degrees, the functions of the electrical equipment are restricted to different degrees, thereby improving the flexibility of handling the insulation faults of the electrical equipment.

[0051] In some embodiments, if the insulation fault of the electrical equipment is a first insulation fault degree, the fault processing further includes: outputting a prompt message for prompting that the operating function is limited;

[0052] If the insulation fault of the electrical equipment is of the second insulation fault degree, the fault processing further includes: outputting prompt information for prompting that the power supply connection is disconnected.

[0053] In the above process, when the function restriction is implemented on the electric equipment, the user is prompted with corresponding prompt information of the restricted function to improve the user experience.

[0054] In some embodiments, the electric device includes a vehicle.

[0055] According to a second aspect of the present application, there is provided a device for processing insulation faults, comprising:

[0056] A detection module, used for performing insulation fault detection during the charging process of the electrical equipment;

[0057] A determination module, configured to determine, in response to detecting an insulation fault, a corresponding fault location strategy according to a degree of insulation fault indicated by a first detection result;

[0058] The positioning module is used to locate the insulation fault based on the fault positioning strategy and determine the faulty device where the insulation fault occurs.

[0059] According to the third aspect of the present application, a battery control device is provided, comprising: a processor, a storage medium and a bus, wherein the storage medium stores machine-readable instructions executable by the processor, and when the electronic device is running, the processor communicates with the storage medium via the bus, and the processor executes the machine-readable instructions to execute the steps of a method for processing an insulation fault as described in any one of the first aspects.

[0081] One aspect of the present application relates to a method for handling insulation faults, in which insulation faults are detected during the charging process of an electrical device. When an insulation fault is detected, a corresponding fault location strategy is determined according to the degree of the insulation fault, and the fault location strategy is executed to determine the faulty device where the insulation fault occurs. The above method sets corresponding fault location strategies for different degrees of insulation faults, so that when insulation faults of different degrees occur in the electrical device during charging, fault location analysis can be flexibly performed according to the degree of the fault, thereby minimizing the impact of insulation fault handling on the charging process.

[0082] It is worth noting that before the present application was filed, if an insulation fault was detected when charging an electrical device (such as a vehicle), regardless of whether the insulation fault was caused by the charging device or the electrical device, the use of the electrical device would be restricted according to the insulation fault of the electrical device, such as limiting charging or disconnecting the charging connection. Such insulation fault handling will have an impact on charging.

[0083] It can be seen that if an insulation fault is detected during the charging process, the use of electrical equipment should not be restricted uniformly, but the equipment with insulation fault should be located. However, if the insulation fault is to be located without changing the existing circuit structure, the charging connection between the electrical equipment and the charging device needs to be disconnected. But when the charging connection is disconnected, the electrical equipment cannot be charged.

[0084] It can be seen that for insulation failures occurring during the charging process, whether it is to uniformly restrict the use of electrical equipment or to locate the fault, it will affect the charging of the electrical equipment, thereby reducing the user experience.

[0085] However, the present application provides a method for handling insulation faults, which can flexibly locate insulation faults occurring during the charging process by setting different fault location strategies for different insulation fault degrees, so as to minimize the impact of insulation fault handling on the charging process.

[0086] Each embodiment is described in detail below.

[0087] A first aspect of an embodiment of the present application provides a method for processing an insulation fault, comprising: Figure 1 Steps 110 to 130 are shown. The method may be performed by an electric device. For example, the electric device may include at least one control device, and the method may be performed by one control device in the electric device, or by a plurality of control devices in coordination.

[0088] Step 110: Perform insulation fault detection during the charging process of the electrical equipment.

[0089] Among them, the electric device can be connected to the charging device for charging. The charging device is used to provide electrical energy. After the electric device is connected to the charging device, it can be charged with direct current.

[0090] As an example, the electrical equipment may be a vehicle, and the charging device may be a charging station.

[0091] The insulation fault detection during the charging process may include: monitoring the insulation resistance of the electrical device during the charging process. When the insulation resistance is lower than a preset resistance threshold, an insulation fault is triggered. For example, the insulation resistance is periodically obtained, and the insulation resistance is compared with the resistance threshold to obtain a first detection result. If the first detection result indicates that an insulation fault occurs, step 120 is executed.

[0092] Step 120: In response to detecting an insulation fault, determining a corresponding fault location strategy according to the insulation fault degree indicated by the first detection result.

[0093] During the charging process of the electric device, the electric device and the charging device are connected to form a large loop. The object of insulation fault detection during the charging process is the loop formed by the electric device and the charging device. In this way, the insulation fault detected during the charging process may be caused by the charging device or the electric device.

[0094] The first detection result of the insulation fault detection may include one or more of the insulation resistance, the comparison result of the insulation resistance and the resistance threshold, or the indication information of whether the insulation fault occurs. In this way, it can be determined whether the insulation fault occurs according to the first detection result. In the case where the first detection result indicates that the insulation fault occurs, the first detection result may also indicate the degree of the insulation fault. For example, the degree of the insulation fault may be determined according to one or more of the insulation resistance included in the first detection result, the comparison result of the insulation resistance and the resistance threshold, or the indication information of the degree of the insulation fault.

[0095] Exemplarily, the resistance threshold may include multiple resistance thresholds. Thus, the multiple resistance thresholds may divide the value range of the resistance into multiple resistance ranges. Different resistance value ranges may correspond to different insulation fault degrees. Thus, it may be determined that the insulation fault degree corresponding to the resistance value range into which the insulation resistance falls is the insulation fault degree indicated by the first detection result.

[0096] In this step, in response to detecting an insulation fault during the charging process, the degree of the insulation fault that has occurred is determined according to the first detection result of the insulation fault, and a corresponding fault location strategy is determined according to the degree of the insulation fault indicated by the first detection result.

[0097] Among them, multiple fault location strategies and the insulation fault degree corresponding to each fault location strategy can be preset. In this way, after obtaining the first detection result, the fault location strategy corresponding to the insulation fault degree indicated by the first detection result can be directly queried.

[0098] Exemplarily, the fault location strategy indicates a fault location method. Different fault location strategies indicate different methods. That is, for different degrees of insulation faults occurring in the circuit formed by the electrical equipment and the charging device, this embodiment adopts different fault location methods.

[0099] Step 130: Locate the insulation fault based on the fault location strategy, and determine the faulty device where the insulation fault occurs.

[0100] After the fault location strategy is determined, the insulation fault is located based on the determined fault location strategy to determine the faulty device where the insulation fault occurs.

[0101] Exemplarily, the determined faulty device may be an electrical device and / or a charging device.

[0102] It can be seen that the insulation fault processing method provided in the embodiment of the present application sets corresponding fault location strategies for different insulation fault degrees, so that when insulation faults of different degrees occur in the electrical equipment during charging, the fault location analysis can be flexibly performed according to the fault degree, thereby minimizing the impact of insulation fault processing on the charging process.

[0103] The following is a detailed explanation of steps 110 to 130.

[0104] As mentioned above, the fault location strategy is used to indicate the fault location method. In some embodiments, the fault location method includes the execution time of the method. That is, the fault location strategy can be used to indicate the execution time of the fault location.

[0105] The so-called execution timing refers to when to execute fault location. As mentioned above, since fault location will affect the charging of the electrical equipment, the fault location execution timing under different insulation fault levels can be controlled by the fault location strategy to minimize the impact on charging.

[0106] As an example, the execution timing may include: executing after charging is completed. That is, the partial fault strategy may indicate that the fault location is executed after the electric device is charged.

[0107] When the cut-off SOC (State of Charge) is reached, charging is determined to be complete. SOC, also known as the remaining capacity, is the ratio of the remaining dischargeable capacity of the device to its fully charged state, and is used to characterize the actual available capacity of the battery.

[0108] It is understandable that, when the electric device completes charging, the electric device and / or the charging device may automatically disconnect the charging connection, or manually disconnect the physical charging connection. In this way, fault location may be performed after the charging connection is disconnected.

[0109] As an example, the execution timing may include: executing when the power of the electric device reaches a preset power threshold. That is, the partial fault strategy may indicate that the fault location is executed when the power of the electric device reaches the power threshold.

[0110] The power of the electric device can be represented by SOC, and the power threshold can be a preset SOC. The power threshold can be set by those skilled in the art according to actual needs. For example, the power threshold can be the power required to ensure the normal operation of the electric device; for example, it can be the power required to ensure that the electric device is sufficient to operate until other charging devices are replaced. This application does not limit this.

[0111] During the charging process, when the power of the power-consuming device reaches the power threshold, the power-consuming device and / or the charging device may automatically disconnect the charging connection, or the physical charging connection may be manually disconnected. Fault location is performed after the charging connection is disconnected.

[0112] It is understandable that if the electrical equipment stops charging due to an insulation fault at the beginning of charging, and the user of the electrical equipment does not promptly discover the charging stop or replace the charging device, it may result in the electrical equipment still having less power after a long period of time. On the one hand, it affects the user experience, and on the other hand, the remaining power of the electrical equipment may not be enough to support its operation until the charging device is replaced. Taking a vehicle as an example, if the remaining power of the vehicle is not enough to support it to drive to the next charging pile for charging, it will cause great trouble to the user. Therefore, by performing fault location after the electrical equipment has been charged to a certain amount of power, it can be ensured that the electrical equipment has enough power to operate.

[0113] As an example, the execution timing may include: executing after charging is terminated. That is, the partial fault strategy may indicate that the fault location is executed after charging of the electric device is terminated.

[0114] The so-called charging suspension refers to the suspension of charging due to a fault during the charging process. Charging suspension may not take into account the current power of the electrical device, and charging is suspended when a fault occurs, such as an insulation fault. For example, charging may be suspended by the electrical device and / or the charging device automatically disconnecting the charging connection. After charging is suspended, fault location is performed.

[0115] Regarding step 120, in some embodiments, it may include: Figure 2 Steps 121-122 are shown.

[0116] Step 121: If the first detection result indicates a first insulation fault degree, determine a corresponding first fault location strategy;

[0117] Step 122: If the first detection result indicates a second insulation fault degree, determine a corresponding second fault location strategy.

[0118] The second insulation fault degree is higher than the first insulation fault degree.

[0119] In this embodiment, the insulation fault degree is divided into two levels, including a first insulation fault degree and a second insulation fault degree. The second insulation fault degree is higher than the first insulation fault degree, which means that the second insulation fault degree is more serious than the first insulation fault degree.

[0120] As described above, multiple resistance thresholds can divide the value range of resistance into multiple resistance ranges, and different resistance value ranges correspond to different insulation fault degrees. In this embodiment, the resistance threshold includes a first resistance threshold and a second resistance threshold. Among them, the first resistance threshold is less than the second resistance threshold. The values ​​of the first resistance threshold and the second resistance threshold can be set by those skilled in the art according to actual needs, or set with reference to laws and regulations, national standards, and industry specifications.

[0121] A first resistance range from a first resistance threshold to a second resistance threshold corresponds to a first insulation fault degree; a second resistance range less than the first resistance threshold corresponds to a second insulation fault degree. The insulation resistance triggers an insulation fault when it is less than the second resistance threshold. Specifically, when the insulation resistance falls within the first resistance range, it is determined that the first detection result indicates a first insulation fault degree, and a corresponding first fault strategy is determined; when the insulation resistance falls within the second resistance range, it is determined that the first detection result indicates a second insulation fault degree, and a corresponding second fault strategy is determined.

[0122] In this embodiment, the degree of insulation fault is divided into two levels, which correspond to the first fault location strategy and the second fault location strategy respectively, so that when the electrical equipment has insulation faults of different degrees during charging, the fault location analysis can be flexibly performed according to the first fault degree and the second fault degree, thereby minimizing the impact of insulation fault processing on the charging process.

[0123] In some embodiments, the first fault location strategy is used to indicate that insulation fault detection is performed after charging is completed.

[0124] The insulation fault detection after charging is completed is used for fault location to determine the faulty device where the insulation fault occurs. That is, the first fault location process is used to indicate: fault location is performed through insulation fault detection after charging is completed.

[0125] It is worth noting that the insulation fault detection during the charging process described in step 110 is different from the insulation fault detection after charging is completed described in the first fault location strategy. As mentioned above, when the electric device is charged, the charging connection will be disconnected. At this time, the object of insulation fault detection is the electric device, and it is no longer the loop formed by the electric device and the charging device.

[0126] Considering that if the insulation fault occurring during the charging process is the first insulation fault level, it means that the insulation fault is a general insulation fault. In order to minimize the impact of insulation fault processing on charging, it is designed to postpone fault location until charging is completed.

[0127] Furthermore, in addition to instructing to perform insulation fault detection after charging is completed, the first fault location strategy may also instruct to reduce the current charging power so as to use the electrical equipment for DC charging or AC charging.

[0128] It is understandable that under the design of postponing fault location until after charging is completed, in order to ensure charging safety, the electrical equipment is also designed to charge at reduced power.

[0129] Optionally, the first fault location strategy may further indicate a reduction range of the charging power. The reduction range may be expressed as a power value or a power percentage.

[0130] Optionally, the first fault location strategy may further indicate a target charging power, so as to reduce the charging power of the electrical device from a current charging power to the target charging power.

[0131] Optionally, if the reduced target charging power is within the DC charging power range, the electrical device can be DC charged at the target charging power.

[0132] Optionally, if the reduced target charging power is within the AC charging power range, and the charging device supports the AC charging mode, the power-consuming device can be AC ​​charged at the target charging power.

[0133] It can be seen that the reduction range of the charging power and / or the target charging power indicated by the first fault location strategy can be determined according to the charging mode supported by the charging device. As a feasible example, in response to the charging connection between the electric device and the charging device, the reduction range of the charging power and / or the target charging power indicated by the first fault location strategy is determined according to the charging mode supported by the charging device, so that when the current charging power is reduced based on the first fault location strategy, the reduced target charging power matches the charging mode supported by the charging device.

[0134] In the case where the first fault location strategy further indicates reducing the current charging power, in some embodiments, the method further includes the steps of:

[0135] During the charging process, a prompt message indicating that the charging time is extended is output.

[0136] When the electric device is charging at reduced power, since the decrease in charging power will extend the charging time, a prompt message can be output to remind the user, such as the driver, that the charging time may be extended, thereby improving the user experience. The output process of the prompt message will be described below and will not be expanded here.

[0137] Optionally, during the charging process, a prompt message for prompting that charging is in progress may also be output.

[0138] Optionally, after charging is completed, a prompt message for prompting that charging is completed may be output.

[0139] In the case of determining the first fault localization strategy, in some embodiments, the above step 130 may include the following steps: Figure 3 Steps 131 - 132 are shown.

[0140] Step 131: in response to the completion of charging of the electric device, controlling the disconnection of the charging connection;

[0141] Step 132: Perform insulation fault detection on the electrical equipment, and determine the faulty equipment according to the obtained second detection result.

[0142] After the electric device completes charging, the electric device and / or the charging device may disconnect the charging connection. For example, if the electric device controls the disconnection of the charging connection, the disconnection of the charging relay may be controlled to disconnect the charging connection.

[0143] After the charging connection is disconnected, the influence of the charging device on the insulation resistance is eliminated, and the object of the insulation fault detection at this time is the electrical equipment. The insulation fault detection performed after charging is completed can obtain a second detection result. The second detection result may include one or more of the insulation resistance, the comparison result of the insulation resistance and the resistance threshold, or the indication information of whether the insulation fault occurs. In this way, it can be determined whether the electrical equipment has an insulation fault based on the second detection result.

[0144] For example, if the first detection result indicates that an insulation fault of a first insulation fault degree has occurred, the second detection result may indicate that an insulation fault of the first insulation fault degree has occurred, or indicate that no insulation fault has occurred.

[0145] If the second detection result indicates that no insulation fault has occurred, it is determined that the faulty device with insulation fault is a charging device; if the second detection result indicates that an insulation fault has occurred, it is determined that the faulty device with insulation fault is an electrical device. This achieves fault location through insulation fault detection after charging is completed.

[0146] In some embodiments, the second fault localization strategy is used to indicate that insulation fault detection is performed after charging is terminated.

[0147] The insulation fault detection performed after charging is terminated is used for fault location to determine the faulty device where the insulation fault occurs. That is, the second fault location process is used to indicate: fault location is performed through insulation fault detection after the termination is completed.

[0148] Similarly, the insulation fault detection during the charging process described in step 110 is different from the insulation fault detection after charging is terminated described in the second fault location strategy. As mentioned above, charging termination refers to the termination of charging due to a fault, such as an insulation fault, during the charging process. When charging is terminated, the charging connection is disconnected, and the object of insulation fault detection is the electrical device, not the circuit formed by the electrical device and the charging device.

[0149] Considering that if the insulation fault occurring during charging is the second insulation fault level, it means that the insulation fault is more serious. In order to ensure the safety of electrical equipment, charging devices and users' life and property, a method is designed to stop charging in response to detecting an insulation fault of the second insulation fault level, and to locate the fault through insulation fault detection.

[0150] In the case of determining the second fault localization strategy, in some embodiments, the above step 130 may include: Figure 4 Steps 133 - 134 are shown.

[0151] Step 133: Controlling the disconnection of charging, and performing insulation fault detection on the electrical equipment;

[0152] Step 134: Determine the faulty device according to the obtained third detection result.

[0153] When charging is stopped due to a fault during the charging process, the electrical equipment can be controlled to disconnect the charging connection, such as controlling to disconnect the charging relay. Similarly, after the charging connection is disconnected, the influence of the charging device on the insulation resistance is eliminated, and the object of the insulation fault detection at this time is the electrical equipment.

[0154] The insulation fault detection performed after charging is terminated can obtain a third detection result. The third detection result may include one or more of the insulation resistance, the comparison result of the insulation resistance and the resistance threshold, or the indication information of whether the insulation fault occurs. In this way, it can be determined whether the electrical equipment has an insulation fault based on the third detection result.

[0155] For example, if the first detection result indicates that an insulation fault of the second insulation fault degree has occurred, the third detection result may indicate that an insulation fault of the second insulation fault degree has occurred, or indicate that no insulation fault has occurred.

[0156] If the third detection result indicates that no insulation fault has occurred, it is determined that the faulty device with insulation fault is a charging device; if the third detection result indicates that an insulation fault has occurred, it is determined that the faulty device with insulation fault is an electrical device. Thus, fault location is achieved through insulation fault detection after the termination is completed.

[0157] Furthermore, in some embodiments, before obtaining the third detection result, the method further includes: outputting no insulation fault information.

[0158] In this embodiment, if it is determined according to the first detection result that an insulation fault of the second insulation fault degree has occurred during the charging process of the electric device, the charging will be stopped and the fault will be located by detecting the insulation fault of the electric device. Before the third detection result is obtained, the output is no insulation fault information. That is, although a more serious insulation fault is detected during the charging process, the electric device still outputs no fault information. This is because it is not yet possible to determine whether the insulation fault of the second insulation fault degree indicated by the first detection result is caused by the electric device or the charging device. If the prompt information of the insulation fault is output on the electric device, it will cause panic to the user. At the same time, if it is subsequently determined according to the third detection result that the insulation fault is caused by the charging device, and the electric device cancels the prompt information of the insulation fault at this time, then from the user's point of view, since the user does not know the judgment logic inside the electric device, the user feels that the electric device first prompts that an insulation fault has occurred, and then cancels the prompt information, which will cause confusion or anxiety to the user and reduce the user's trust in the electric device. Therefore, in this embodiment, before the third detection result is obtained and the faulty device is determined, the output is no insulation fault information. After the faulty device is determined according to the third detection result, if the faulty device is an electrical device, insulation fault information is output; if the faulty device is a charging device, no insulation fault information is output.

[0159] Optionally, before disconnecting the charging connection and obtaining the third detection result, prompt information for prompting a charging failure may also be output.

[0160] Based on any of the above embodiments, after determining that a faulty device has occurred, the method further includes:

[0161] According to the type of the faulty equipment, a fault handling method for the electrical equipment is determined.

[0162] After the insulation fault is located, the type of the faulty device can be determined. The type of the faulty device can be an electrical device or a charging device. Regardless of whether the type of the faulty device is an electrical device, fault processing can be performed on the electrical device. Different fault processing can be performed on the electrical device according to different types of faulty devices.

[0163] In some embodiments, the fault handling of the electric device is as follows: Figure 5 Steps 510 to 520 are shown.

[0164] Step 510: If the type of the faulty device is a charging device, determine that the fault handling includes allowing the function of the power-consuming device to be used.

[0165] If the faulty device is a charging device, it means that the insulation fault indicated by the first detection result is caused by the charging device, and the electrical device does not have an insulation fault. Therefore, the fault handling of the electrical device may include allowing the function of the electrical device to be used, that is, the function of the electrical device can be used without restriction.

[0166] Step 520: If the type of the faulty device is the electric device, determine that the fault handling includes restricting the electric device from using a target function.

[0167] If the type of the faulty device is an electrical device, it means that the insulation fault indicated by the first detection result is caused by the electrical device. At this time, the use of at least some functions of the electrical device should be restricted. Therefore, the fault handling of the electrical device may include restricting the use of the target function of the electrical device.

[0168] Further, regarding step 510, in some embodiments, when the type of the faulty device is a charging device, if it is determined according to the third detection result that the insulation fault of the charging device is a second insulation fault degree, the fault processing of the electrical device may further include:

[0169] Output a prompt message for replacing the charging device.

[0170] In this embodiment, if an insulation fault of the second insulation fault degree is determined to have occurred during the charging process of the electric device according to the first detection result, the charging is terminated. If it is determined according to the third detection result that an insulation fault of the second insulation fault degree has occurred in the charging device, it can be known that the electric device has not had an insulation fault. Therefore, the fault handling of the electric device includes allowing the functional use of the electric device. At the same time, since the charging has been terminated, the fault handling may also include outputting a prompt message for replacing the charging device to prompt the user to charge the electric device with the next charging device.

[0171] In some embodiments, the target function described in step 520 may include an operating function of the electric device. The operating function refers to a function that can be implemented when the electric device is running, and the specific operating function is determined according to the type of the electric device. For example, if the electric device is a vehicle, the operating function may include but is not limited to a driving function, a charging function, etc.

[0172] In this way, when the type of the faulty device is an electrical device, if it is determined according to the second detection result that the insulation fault of the electrical device is of the first insulation fault degree, the fault processing of limiting the use of the target function of the electrical device in step 520 includes:

[0173] The operating parameters of the restricted operating function are not greater than the preset threshold.

[0174] That is, when a general insulation fault occurs in the electrical equipment, the electrical equipment is restricted from using operating functions when the operating parameters are not greater than a preset threshold value, so as to ensure that the operating functions are used in a safe manner.

[0175] For example, if the electrical device is a vehicle, the speed parameter in the driving function may be limited to be no greater than a preset threshold, that is, the vehicle may be controlled to travel at a limited speed.

[0176] On this basis, in addition to limiting the operating parameters of the operating function to be not greater than a preset threshold, the fault processing may also optionally include outputting prompt information for prompting that the operating function is limited.

[0177] Taking the electrical equipment being a vehicle as an example, the prompt message indicating that the operating function is restricted may include: "High-voltage insulation fault, driving restricted, maximum speed limited to V km / h, please make an appointment for maintenance."

[0178] In some embodiments, the target function described in step 520 may include a power supply connection function of the electrical device. The power supply connection function refers to the power supply connection function between the power supply system in the electrical device and the load system. The power supply system includes, for example, a battery. When the power supply connection function is available, the power supply system can provide electrical energy to the load system through connection. When the power supply connection function is not available, the power supply system cannot provide electrical energy to the load system, resulting in the electrical device being unable to be powered on and operated.

[0179] In this way, when the type of the faulty device is an electrical device, if the insulation fault of the electrical device is determined to be the second insulation fault degree according to the third detection result, the fault processing of limiting the use of the target function of the electrical device in step 520 includes:

[0180] The control power connection is disconnected.

[0181] That is, when a serious insulation fault occurs in the electrical equipment, the power connection restriction function is unavailable to control the power connection to be in a disconnected state, so that the power supply system in the electrical equipment cannot provide power to the load system and the electrical equipment cannot be powered on and operated.

[0182] For example, if the electrical device is a vehicle, the main relay can be controlled to be in a disconnecting position, limiting the power supply connection function to be unavailable, so that the vehicle battery cannot provide electrical energy and the vehicle cannot be powered on and driven.

[0183] On this basis, in addition to controlling the power supply connection to be in a disconnected state, the fault processing may optionally include outputting prompt information for prompting that the power supply connection is disconnected.

[0184] Taking the case where the electrical equipment is a vehicle, the prompt message indicating that the power supply connection is disconnected may include: "High voltage insulation fault, charging and driving prohibited, please contact after-sales maintenance."

[0185] It can be seen that the insulation fault processing method provided by the present application can distinguish whether the insulation fault is caused by an electrical device or a charging device. If the faulty device is an electrical device, the user is reminded to repair it, and the functional restrictions of the electrical device are imposed to different degrees according to the degree of insulation fault to protect personnel safety. If the faulty device is a charging device, the functional use of the electrical device is allowed to avoid interfering with the user's use of the electrical device. At the same time, corresponding prompt information is output in conjunction with different fault processing of the electrical equipment to remind the user to make an appointment for inspection, repair equipment, replace the charging device, etc.

[0186] In some embodiments, the electrical equipment includes a power supply system. The power supply system may include a battery and a power supply control device. The insulation fault processing method provided in the present application may be executed by the power supply control device.

[0187] In addition, the electrical equipment also includes an equipment control device. When an insulation fault of a first insulation fault degree is determined to have occurred according to the first detection result during the charging process of the electrical equipment, the power supply control device may report the insulation fault to the equipment control device. Exemplarily, the mark bit of the insulation fault may be marked. When the second detection result indicates that the insulation fault disappears, it can be determined that the faulty device is a charging device, and the power supply control device stops reporting the insulation fault to the equipment control device and clears the mark in the mark bit of the insulation fault. When the second detection result indicates that the insulation fault exists, it can be determined that the faulty device is an electrical device, and the power supply control device continues to report the insulation fault to the equipment control device.

[0188] When an insulation fault of the second insulation fault degree is determined to have occurred according to the first detection result during the charging process of the electrical device, the power supply control device may report to the device control device that there is no insulation fault. Exemplarily, the mark bit of the insulation fault may be kept unmarked so that the electrical device outputs information that there is no insulation fault. When the third detection result indicates that the insulation fault disappears, it can be determined that the faulty device is a charging device, and the power supply control device may continue to report to the device control device that there is no insulation fault. When the third detection result indicates that the insulation fault exists, it can be determined that the faulty device is an electrical device, and the power supply control device reports the insulation fault to the device control device so that the electrical device outputs insulation fault information.

[0189] The following description will be continued by taking a vehicle as an example of an electrical device. The vehicle includes multiple control devices, such as but not limited to a battery pack control device, a vehicle domain control device, a cockpit domain control device, and the like.

[0190] Among them, the above-mentioned power supply control device can be a battery pack control device, and the battery pack control device can be, for example, a BMS (Battery Management System), which is responsible for monitoring the insulation resistance of the entire vehicle, reporting insulation faults to the vehicle domain control device, and controlling the DC charging process.

[0191] The above-mentioned equipment control device may be a vehicle domain control device. For example, the vehicle domain control device may be a VCU (Vehicle Control Unit), which is responsible for vehicle system fault handling, high-voltage connection control, and display information sending, and is the main control of the vehicle.

[0192] The cockpit domain control device is used for human-computer interaction prompts and remote prompt information sending.

[0193] In some embodiments, the vehicle may also be connected to a remote control device for communication. The remote control device is, for example, a user's mobile device, such as a mobile phone. For example, the cockpit domain control device may be connected to a remote control device in the remote control device for communication. The remote control device is responsible for remote information display.

[0194] like Figure 6 As shown, during the charging process of the electric device, the battery pack control device performs insulation fault detection. If the insulation resistance R is detected to fall within the first resistance range [x1, x2], it is determined that an insulation fault of the first insulation fault degree has occurred. At this time, it can be determined to execute the first fault location strategy.

[0195] Based on the first fault location strategy, the battery pack control device reports the general insulation fault and the DC charging status during charging to the vehicle domain control device. The vehicle domain control device sends a prompt message to the cockpit domain control device according to the DC charging status during charging, so that the cockpit domain control device outputs a prompt message in the vehicle to indicate that charging is in progress. At the same time, the cockpit domain control device can also synchronize the prompt message to the remote control device, so that the remote control device also displays the prompt message to indicate that charging is in progress.

[0196] In addition, based on the first fault location strategy, the battery pack control device controls the reduction of the charging power so that the vehicle performs reduced-power charging. At this time, the fast charging relay of the vehicle remains closed. Charging is completed when the current SOC of the vehicle reaches the cutoff SOC. At this time, the battery pack control device reports the DC charging status of charging completion to the vehicle domain control device. The vehicle domain control device sends a prompt message to the cockpit domain control device based on the DC charging status of charging completion, so that the cockpit domain control device outputs a prompt message in the vehicle to prompt the completion of charging. At the same time, the cockpit domain control device can also synchronize the prompt message to the remote control device, so that the remote control device also displays the prompt message for prompting the completion of charging.

[0197] At the same time, in response to the completion of charging of the vehicle, the battery pack control device controls the disconnection of the fast charging relay and performs insulation fault detection on the vehicle. If the second detection result obtained indicates that the insulation fault disappears and the faulty device is determined to be a charging device, the general insulation fault is cleared and the system function of the whole vehicle is not restricted. If the second detection result obtained indicates that there is an insulation fault of the first insulation fault degree and the faulty device is determined to be a vehicle, the battery pack control device continues to report the general insulation fault to the whole vehicle domain control device. At the same time, the driving function of the vehicle is restricted and the speed is limited to below the preset speed value. The whole vehicle domain control device sends a prompt message to the cockpit domain control device based on the general insulation fault and the restricted driving function, so that the cockpit domain control device outputs the prompt message of "high voltage insulation fault, limited driving, limited maximum speed V km / h, please make an appointment for maintenance" in the vehicle. At the same time, the cockpit domain control device can also synchronize the prompt message to the remote control device so that the remote control device also displays the prompt message.

[0198] like Figure 7 As shown, during the charging process of the electric device, the battery pack control device performs insulation fault detection. If the insulation resistance R is detected to fall into the second resistance range [0, x1], it is determined that an insulation fault of the second insulation fault degree has occurred. At this time, it can be determined to execute the second fault location strategy.

[0199] Based on the second fault location strategy, the battery pack control device reports the DC charging status without insulation fault and charging fault to the vehicle domain control device. The vehicle domain control device sends prompt information to the cockpit domain control device according to the DC charging status of the charging fault, so that the cockpit domain control device outputs the prompt information for prompting the charging fault in the vehicle. At the same time, the cockpit domain control device can also synchronize the prompt information with the remote control device, so that the remote control device also displays the prompt information for prompting the charging fault.

[0200] In addition, based on the first fault location strategy, the battery pack control device controls the disconnection of the fast charging relay to terminate the charging of the vehicle. At this time, the main relay remains connected. Subsequently, the battery pack control device performs insulation fault detection on the vehicle. If the second detection result obtained indicates that the insulation fault disappears, and it is determined that the faulty device is the charging device, the battery pack control device reports to the vehicle domain control device that there is no insulation fault and the system functions of the vehicle are not restricted. At this time, the vehicle domain control device sends a prompt message of the charging device failure to the cockpit domain control device, so that the cockpit domain control device outputs a prompt message in the vehicle that "the charging device is faulty, please replace the charging device and recharge". At the same time, the cockpit domain control device can also synchronize the prompt message to the remote control device so that the remote control device also displays the prompt message.

[0201] If the second detection result obtained indicates the existence of an insulation fault of the second insulation fault degree, it is determined that the faulty device is a vehicle, and the battery pack control device reports a serious insulation fault to the vehicle domain control device. The vehicle domain control device prohibits the charging and driving of the vehicle, and at the same time requests the battery pack control device to disconnect the high-voltage power supply connection. The battery pack control device disconnects the main relay so that the on-board battery no longer provides high-voltage power supply. At the same time, the vehicle domain control device sends a prompt message of a serious insulation fault to the cockpit domain control device, so that the cockpit domain control device outputs a prompt message in the vehicle that reads "High-voltage insulation fault, charging and driving prohibited, please contact after-sales maintenance." At the same time, the cockpit domain control device can also synchronize the prompt message to the remote control device so that the remote control device also displays the prompt message.

[0202] The above embodiments involve the output of various prompt information, including prompt information for indicating that the charging time is extended, prompt information for indicating that charging is in progress, prompt information for indicating that charging is completed, prompt information for indicating charging failure, prompt information for prompting replacement of the charging device, prompt information for prompting that the operating function is limited, prompt information for prompting that the power supply connection is disconnected, etc. These prompt information can be output on the power-consuming device, such as the cockpit screen of the vehicle; or they can be synchronized to the user's remote control device for output.

[0203] To this end, the present application provides a push system for synchronizing prompt information between a user device and a remote control device. Figure 8 8 is a block diagram of a push system 800 of some embodiments of the present application. For example, the push system 800 may be a service platform for real-time message push. The push system 800 may include one or more of a server 810, a network 820, an electric device end 830, a remote control end 840, and a database 850, and the server 810 may include a processor for executing instruction operations.

[0204] In some embodiments, the server 810 may be a single server or a server group. The server group may be centralized or distributed (for example, the server 810 may be a distributed system). In some embodiments, the server 810 may be local or remote relative to the terminal. For example, the server 810 may access information and / or data stored in the power-consuming device 830, the remote control terminal 840, or the database 850, or any combination thereof, via the network 820. As another example, the server 810 may be directly connected to at least one of the power-consuming device 830, the remote control terminal 840, and the database 850 to access the stored information and / or data.

For example, the server 810 can obtain prompt information from the power-consuming device end 830 via the network 820. For another example, the power-consuming device 830 can directly send prompt information to the remote control end 840 via the network 820. In some embodiments, the network 820 can be any type of wired or wireless network, or a combination thereof.

For example, the network 820 may include a wired or wireless network access point, such as a base station and / or a network switching node, through which one or more components of the push system 800 may connect to the network 820 to exchange data and / or information.

[0207] In some embodiments, the power-consuming device end 830 refers to a client installed in the power-consuming device, which can be used to communicate with clients of other devices.

[0208] In some embodiments, the remote control terminal 840 is connected to the power-consuming device terminal 830 in communication, for example, through the network 820 and / or the server 810, to receive the prompt information sent by the power-consuming device terminal 830. The remote control terminal 840 may include but is not limited to a client corresponding to the user of the power-consuming device. The remote control terminal 840 may be installed in the user's electronic device.

[0209] In some embodiments, the user's electronic device may include a mobile device, a tablet computer, or a laptop computer, etc., or any combination thereof. In some embodiments, the mobile device may include a smart home device, a wearable device, a smart mobile device, a virtual reality device, or an augmented reality device, etc., or any combination thereof. In some embodiments, the smart home device may include a smart lighting device, a control device for a smart electrical device, a smart monitoring device, a smart TV, a smart camera, or an intercom, etc., or any combination thereof.

[0210] As a feasible example, the electric device may be a vehicle, and the electric device end 830 may be a communication client installed in the vehicle system. The remote control end 840 may be a vehicle user, such as a client installed in a mobile phone used by a driver. In this way, the vehicle may push prompt information to the driver through the push system 800.

[0211] The database 850 may store data and / or instructions. In some embodiments, the database 850 may store data obtained from the power device end 830 and / or the remote control end 840. In some embodiments, the database 850 may store data and / or instructions of the exemplary methods described in the present application. In some embodiments, the database 850 may include a mass storage device, a removable storage device, a volatile read-write memory, or a read-only memory (ROM), etc., or any combination thereof.

As an example only, the cloud platform may include a private cloud, a public cloud, a hybrid cloud, a community cloud, a distributed cloud, a cross-cloud, a multi-cloud, or other similar, etc., or any combination thereof.

[0212] In some embodiments, the database 850 can be connected to the network 820 to communicate with one or more components in the push system 800 (e.g., the server 810, the powered device 830, the remote control 840, etc.). One or more components in the push system 800 can access the data or instructions stored in the database 850 via the network 820. In some embodiments, the database 850 can be directly connected to one or more components in the push system 800 (e.g., the server 110, the powered device 830, the remote control 840, etc.); or, in some embodiments, the database 850 can also be part of the server 810.

[0213] In some embodiments, one or more components in the push system 800 (e.g., server 810, power user end 830, remote control end 840, etc.) may have access to database 850. In some embodiments, when certain conditions are met, one or more components in the push system 800 may read and / or modify information related to the power user, the remote control, or the public, or any combination thereof. For example, the server 810 may read and / or modify information of one or more users after receiving the prompt information. As another example, the remote control end 840 may access information related to the power user when receiving the prompt information from the power user end 830, but the remote control end 840 may not modify the relevant information of the power user.

[0214] Fig. 9 A schematic diagram of exemplary hardware and software components of an electronic device 900 including a server 810, a power-consuming device end 830, and a remote control end 840 that can implement the concept of the present application according to some embodiments of the present application is shown. For example, a processor can be used on the electronic device 900 and used to perform the functions in the present application.

[0215] The electronic device 900 may be a general-purpose computer or a special-purpose computer, both of which may be used to implement a method for processing insulation faults in the present application. Although only one computer is shown in the present application, for convenience, the functions described in the present application may be implemented in a distributed manner on multiple similar platforms to balance the processing load.
