[0027] Insulation fault detection in the battery management system (BMS) involves pulse high voltage injection between the positive or negative voltage or insulation resistance calculation via a balanced bridge. This can only report insulation faults when a failure occurs, but cannot accurately locate the point of failure.

[0028] Flying cars can fly in the air or drive on land. Flying cars usually include a flying body and a land body. The high-voltage system architecture involved in flying cars is more complex than that of general equipment or new energy vehicles, and many high-voltage components are coupled together. When an insulation fault occurs, it is difficult to quickly locate the fault source.

[0029] In response to the above problems, an embodiment of the present application provides a method for locating insulation faults of a flying car. When an insulation fault occurs in the flying car, the method can quickly locate the source of the fault by controlling the power on and off of the flying body and the land body of the flying car, which is beneficial to improving the efficiency of troubleshooting and user experience.

[0030] The technical solution of the embodiments of the present application is described in detail below with reference to the accompanying drawings.

[0031] Figure 1 It is a flow chart of an insulation fault location method for a flying car shown in an embodiment of the present application.

[0032] See also Figure 1 A method for locating insulation faults of a flying car, the flying car comprising a flying body and a land body, the method comprising:

[0033] Step 101, in response to detecting an insulation fault in the flying car, power on and off control is performed on the flying body and the land body of the flying car.

[0034] Step 102: Determine the location of the fault source according to the insulation fault detection result obtained during power on and off control.

[0035] It can be understood that a flying car generally includes a flying body and a terrestrial body, such as an aircraft and a car. The aircraft high-voltage system may include a battery that provides power and a high-voltage load, such as a battery system and a high-voltage circuit. The car high-voltage system may include a battery that provides power and a high-voltage load, such as a battery system and a high-voltage circuit.

[0036] In the method for locating the insulation fault of the flying car of the embodiment of the present application, it is possible to detect whether the flying car has an insulation fault when performing fault detection on the flying car. If the current flying car does not detect an insulation fault, a message "currently no insulation fault" is fed back to the user; if the current flying car detects an insulation fault, the insulation fault of the flying car is further located.

[0037] It can be understood that in the insulation fault locating method of the flying car in the embodiment of the present application, after the insulation fault is detected in the flying car, it is necessary to perform power on and off control on the flying body and the land body of the flying car. Each power on and off control can obtain insulation fault detection results reflecting the locations of different fault sources. Therefore, the complex high-voltage components of the flying car can be further quickly and accurately checked and located, thereby quickly locating the location of the fault source.

[0038] For example, the flying body and the land body can be controlled to be powered on separately; the high-voltage circuit of the flying body and the relay of the battery system of the flying body can be disconnected before powering on; the high-voltage circuit of the land body and the relay of the battery system of the land body can be disconnected before powering on, and so on.

[0039] The insulation fault locating method of the flying car in the embodiment of the present application can quickly locate the fault source by controlling the power on and off of the flying body and the land body of the flying car when an insulation fault occurs in the flying car, which is beneficial to improving the efficiency of fault detection and user experience; at the same time, it can also reduce the difficulty of fault detection for after-sales maintenance personnel.

[0040] In some embodiments, the location of the fault source may occur at a connection section between the flying object and the terrestrial object.

[0041] The connection between the flying body and the land body can be disconnected so that the flying body and the land body can each perform insulation fault detection. If neither the flying body nor the land body detects an insulation fault, the fault source can be located at the connection section between the flying body and the land body.

[0042] In some embodiments, the location of the fault source may be present in the flying object, such as the fault source is located in the high-voltage circuit of the flying object, or the fault source is located in the battery system of the flying object.

[0043] For example, the flying body and the land body each perform insulation fault detection. If the flying body detects the existence of an insulation fault, it means that the fault source may be located in the flying body. Then, by further power on and off control, according to the insulation fault detection results obtained during the power on and off control, the fault source can be located in the high-voltage circuit of the flying body, or in the battery system of the flying body.

[0044] In some embodiments, the location of the fault source may occur in the land vehicle, such as the fault source is located in the high-voltage circuit of the land vehicle, or the fault source is located in the battery system of the land vehicle.

[0045] For example, the flying body and the land body each perform insulation fault detection. If the land body detects an insulation fault, it means that the fault source may be located on the land body. Then, by further power on and off control, according to the insulation fault detection results obtained during the power on and off control, the fault source can be located in the high-voltage circuit of the land body, or in the battery system of the land body.

[0046] The insulation fault locating method of the flying car in the embodiment of the present application can accurately determine the location of the fault source, such as the location of the fault source is located in the connecting section between the flying body and the land body; the fault source is located in the high-voltage circuit of the flying body; the fault source is located in the battery system of the flying body; the fault source is located in the high-voltage circuit of the land body; the fault source is located in the battery system of the land body, etc. This is conducive to fault maintenance personnel to conduct effective fault detection and quickly implement maintenance.

[0047] In some embodiments, determining the location of the fault source according to the insulation fault detection result obtained during power on and off control includes at least one of the following:

[0048] For example, 1. After the flying body and the land body are powered on respectively, insulation fault detection is performed to obtain the insulation fault detection results of the flying body and the land body respectively, and when the insulation fault detection results of the flying body and the land body are both that there is no insulation fault, it is determined that the fault source is located in the connection section between the flying body and the land body.

[0049] In some embodiments, the flying object and the terrestrial object are excluded to determine that the fault source is located in the connection section between the flying object and the terrestrial object.

[0050] For example, 2. After disconnecting the relay of the high-voltage circuit of the flying body and the battery system of the flying body, an insulation fault detection is performed to obtain the insulation fault detection result of the flying body, and when the insulation fault detection result of the flying body is that there is no insulation fault, it is determined that the fault source is located in the high-voltage circuit of the flying body.

[0051] For example, 3. After disconnecting the relay of the high-voltage circuit of the flying body and the battery system of the flying body, an insulation fault detection is performed to obtain the insulation fault detection result of the flying body, and when the insulation fault detection result of the flying body indicates that an insulation fault exists, it is determined that the fault source is located in the battery system of the flying body.

[0052] In some embodiments, the fault source is first located in the flying body; then the relays of the high-voltage circuit of the flying body and the battery system of the flying body are disconnected; then the flying body controller reports the low-voltage power supply of the whole machine, keeps the flying body BMS from entering the dormant state, and continues the insulation detection. Finally, if the insulation fault detection result of the flying body is that there is no insulation fault, it is determined that the fault source is located in the high-voltage circuit of the flying body; if the insulation fault detection result of the flying body is that there is an insulation fault, it is determined that the fault source is located in the battery system of the flying body.

[0053] For example, 4. After disconnecting the high-voltage circuit of the land vehicle and the relay of the battery system of the land vehicle, an insulation fault detection is performed to obtain the insulation fault detection result of the land vehicle, and when the insulation fault detection result of the land vehicle is that there is no insulation fault, it is determined that the fault source is located in the high-voltage circuit of the land vehicle;

[0054] For example, 5. After disconnecting the high-voltage circuit of the land vehicle and the relay of the battery system of the land vehicle, perform insulation fault detection to obtain the insulation fault detection result of the land vehicle, and when the insulation fault detection result of the land vehicle indicates that an insulation fault exists, determine that the fault source is located in the battery system of the land vehicle.

[0055] In some embodiments, the fault source is first located on the land vehicle; then the relays of the high-voltage circuit of the land vehicle and the battery system of the land vehicle are disconnected; then the land vehicle controller reports the low-voltage power supply of the whole machine, keeps the land vehicle BMS from entering the dormant state, and continues the insulation detection. Finally, if the insulation fault detection result of the land vehicle is that there is no insulation fault, it is determined that the fault source is located in the high-voltage circuit of the land vehicle; if the insulation fault detection result of the land vehicle is that there is an insulation fault, it is determined that the fault source is located in the battery system of the land vehicle.

[0056] The insulation fault locating method of the flying car in the embodiment of the present application can provide targeted power on and off control, such as disconnecting the relays of the high-voltage circuit and the battery system, which is conducive to quickly locating the location of the fault source and improving the efficiency of troubleshooting and user experience.

[0057] In some embodiments, the insulation fault locating method of the flying car further includes: starting insulation fault locating detection of the flying car through a diagnostic instrument; wherein the diagnostic instrument is configured with an insulation fault detection mode, and when it is detected that the insulation fault detection mode is turned on, insulation fault detection is performed on the flying car.

[0058] For example, when the diagnostic instrument is configured with an insulation fault detection mode and the insulation fault detection mode is turned on, the connection between the diagnostic instrument and the flying car is disconnected, and the flying car performs a power-on BMS test. After detecting that the insulation fault detection mode is turned on, it is determined whether the current fault exists.

[0059] The insulation fault locating method of the flying car in the embodiment of the present application can start the insulation fault locating by means of a diagnostic instrument, which can ensure safety, so as to reduce the difficulty of troubleshooting and quickly locate the insulation fault for users who provide after-sales service when facing a device such as a flying car with a coupled high-voltage architecture.

[0060] In order to better understand the present application, the content of the present application is further explained below in conjunction with the embodiments, but the present application is not limited to the following embodiments.

[0061] Figure 2 It is another flow chart of the insulation fault location method of the flying car shown in the embodiment of the present application.

[0062] See also Figure 2 , in operation S210 , insulation fault is detected.

[0063] For example, in the diagnostic mode on the vehicle side, an insulation fault diagnostic mode is added by adding a diagnostic ID, and the insulation fault diagnostic mode is turned on by a diagnostic instrument. After the diagnostic instrument turns on the insulation fault diagnostic mode, the diagnostic instrument is connected to the entire vehicle, and the entire vehicle is powered on. After the BMS detects that the insulation fault diagnostic mode is on, insulation fault detection is performed.

[0064] In operation S220 , it is determined whether an insulation fault exists.

[0065] For example, determine whether there is a current insulation fault.

[0066] In operation S231, if yes, it is determined whether the aircraft is connected to the car.

[0067] For example, if an insulation fault exists, determine whether the aircraft is connected to the car.

[0068] In operation S232 , if not, it is fed back that there is no insulation fault, and the insulation fault diagnosis mode is exited.

[0069] For example, if the insulation fault does not exist, a text prompt will be given on the vehicle computer indicating that there is currently no insulation fault.

[0070] In operation S240 , if yes, the connection is disconnected, and the aircraft and the car perform insulation fault detection.

[0071] For example, if the aircraft is currently connected to the car, the connection is disconnected; after the high-voltage connection is disconnected, the aircraft and the car each perform insulation fault detection.

[0072] After operation S240 , in operation S250 , it is determined whether there is no insulation fault in the aircraft and the car.

[0073] For example, the aircraft and the car feed back insulation fault detection results to determine whether there is no insulation fault in both the aircraft and the car.

[0074] In operation S261 , if no, the aircraft has an insulation fault, but the car does not have an insulation fault.

[0075] For example, only the aircraft reports an insulation fault, but the car does not report an insulation fault.

[0076] In operation S262 , if no, the automobile has an insulation fault, but the aircraft does not have an insulation fault.

[0077] For another example, only the car reports an insulation fault, but the aircraft does not report an insulation fault.

[0078] In operation S263, if yes, troubleshoot the connection segment.

[0079] For another example, if neither the aircraft nor the car reports an insulation fault, the insulation failure source is located as the high-voltage connection section between the car and the aircraft, and the connection section is then checked for faults.

[0080] After operation S261, in operation S271, the aircraft-side BMS requests to disconnect the aircraft-side battery high-voltage relay to disconnect the high-voltage circuit; the aircraft controls the low-voltage power supply, the aircraft-side BMS does not enter the sleep mode, and the insulation fault is detected.

[0081] For example, the aircraft-side BMS requests to disconnect the battery high-voltage relay on the aircraft side. After disconnecting the high-voltage circuit on the aircraft side, the aircraft whole machine controller reports low-voltage power supply for the whole machine, keeping the aircraft-side BMS from entering a sleep state and continuing insulation fault detection.

[0082] In operation S281, it is determined whether an insulation fault exists.

[0083] For example, determine whether an insulation fault is reported at this time.

[0084] In operation S291, if not, the high voltage circuit is troubleshooted.

[0085] For example, if the insulation fault is no longer reported, the high-voltage circuit on the aircraft side is checked for faults.

[0086] In operation S292, if yes, the battery system is troubleshooted.

[0087] For example, if the insulation fault is still reported, troubleshoot the battery on the aircraft side.

[0088] After operation S262, in operation S272, the vehicle-side BMS requests to disconnect the vehicle-side battery high-voltage relay to disconnect the high-voltage circuit; the whole vehicle controls the low-voltage power supply, the vehicle-side BMS does not enter the sleep mode, and the insulation fault is detected.

[0089] For example, the vehicle-side BMS requests to disconnect the high-voltage relay at the vehicle-side battery end, disconnect the high-voltage circuit at the vehicle end, and the vehicle controller maintains the low-voltage power supply for the vehicle, keeps the vehicle-side BMS from entering a sleep state, and continues to perform insulation fault detection.

[0090] In operation S282, it is determined whether an insulation fault exists.

[0091] For example, determine whether an insulation fault is reported at this time.

[0092] In operation S293, if yes, the battery system is troubleshooted.

[0093] For example, if the insulation fault is no longer reported, the high-voltage circuit on the vehicle side is checked for faults.

[0094] In operation S294, if not, the high voltage circuit is troubleshooted.

[0095] For example, if the insulation fault is still reported, troubleshoot the battery at the vehicle end.

[0096] The insulation diagnosis mode can enter the closed state by default after being turned on by the diagnostic instrument and a complete insulation fault detection is performed (operation S210-operation S294), or it can enter the closed state by default after the low-voltage power supply is disconnected and the controller is reset in this mode. If the insulation fault detection state needs to be entered again, the diagnostic instrument needs to be manually turned on again.
