In addition, the character "/" herein generally indicates that the former and latter related objects are in an "or" relationship.

Examples

Referring to fig. 1, a first embodiment of the present invention provides a fault handling method applied to a fault handling system, where the fault handling system includes a fault handling server and a self-testing device connected to the fault handling server, and the self-testing device is provided with a BMS module, and the method includes the following steps:

s101: the fault processing server sends a self-checking starting instruction to the self-checking device according to a preset strategy;

s102: the self-checking device responds to the self-checking starting instruction, controls the BMS module to be connected with the charging equipment when the charging equipment to be detected is determined to be in an idle state, detects the charging equipment aiming at the charging fault of the BMS module to obtain a detection result, records fault information if the detection result shows that the charging equipment has the charging fault, and uploads the fault information to the fault processing server;

s103: and after receiving the fault information, the fault processing server executes a control instruction corresponding to the fault information.

Specifically, in the prior art, charging fault detection usually requires that a vehicle is connected to a charging device and then triggers the charging device to start charging, and then detects a fault occurring during charging, so that after the vehicle travels to the position of the charging device, the charging device triggers charging fault detection only when the vehicle is actually charged, if the charging device has a charging fault, the charging device cannot charge the vehicle, and the vehicle runs for a while, and if the cruising ability of the vehicle is not enough to travel to a new charging device, a lot of subsequent unnecessary processing expenses can be caused.

The fault handling method in this embodiment is applied to a fault handling system, where the fault handling system is connected to a plurality of self-checking devices, and the self-checking devices are arranged opposite to corresponding charging devices, and are used to detect faults and standby faults when the charging devices are charged. The charging device may be a charging device of different manufacturers or a charging device corresponding to the same manufacturer, and may be set according to actual needs in a specific implementation process, where this embodiment is not limited.

The self-checking device may be a device independent from the charging apparatus, or may be a part of the charging apparatus, and this embodiment is not limited herein. A BMS (Battery management system) module is provided in the self-inspection apparatus, and functions as the BMS in the new energy electric vehicle. Because the charging equipment is distributed at each position of a city, and each charging equipment is correspondingly provided with the self-checking device, the fault processing server in the fault processing system is connected with the self-checking devices at a plurality of different positions.

In order to handle the charging failure of the charging device more timely, in step S101, the failure handling server sends a self-checking start instruction to each self-checking device connected to the failure handling server according to a preset policy, so that the self-checking device performs failure detection on the charging device bound to the self-checking device. In the specific implementation process, the method can be realized by the following steps:

sending a self-checking starting instruction to the self-checking device according to a preset self-checking period; and/or

And sending a self-checking starting instruction to the self-checking device at the appointed detection time.

Specifically, in this embodiment, the fault handling server may issue a self-checking start instruction according to a preset self-checking period to trigger the self-checking device to start self-checking, or issue a self-checking start instruction at regular time to trigger the self-checking device to start self-checking.

Further, the fault handling server may issue the self-checking start instruction according to a uniform preset self-checking period or specified detection time for the self-checking devices of the whole network, or may configure the preset self-checking period or specified detection time of the charging device in a personalized manner according to the difference of the charging devices, and in a specific implementation process, the fault handling server may select the fault handling server according to actual needs, which is not limited in this embodiment.

And the fault processing server sends a self-checking starting instruction to the self-checking device according to a preset self-checking period or specified detection time. Furthermore, in step S102, after receiving the self-checking on command, the self-checking device responds to the self-checking on command, and sends a state detection command to the charging device, the self-checking device and the charging device may perform communication interaction, the charging device may feed back its state information to the self-checking device based on the state detection command, and the self-checking device may determine whether the charging device is in an idle state based on the state information. Or, the fault handling server directly sends a self-checking start instruction to the charging equipment according to a preset self-checking period or specified detection time, after the charging equipment receives the self-checking start instruction, the charging equipment feeds back own state information to the self-checking device, and the self-checking device determines whether the charging equipment is in an idle state or not based on the state information.

Further, in this embodiment, when the preset self-checking periods corresponding to different self-checking devices are configured individually, the preset self-checking periods may be set according to the failure frequency of the charging device. Specifically, historical fault information of the charging equipment is maintained in the fault processing server, for each charging equipment, the fault frequency of the charging equipment is counted according to the historical fault information, a preset self-checking period is determined according to the fault frequency of the current charging equipment, and in order to find a fault in time, the preset self-checking period needs to be set to be less than or equal to the fault frequency of the current charging equipment.

Further, in this embodiment, when the preset self-checking periods corresponding to different self-checking devices are configured in a unified manner, or the fault processing server maintains the fault information of the charging equipment in the whole network, obtains the historical faults of the charging equipment in the whole network, counts the fault frequency in the whole network, and sets the preset self-checking period according to the fault frequency in the whole network, where the preset self-checking period needs to be less than or equal to the fault frequency in the whole network.

In a specific implementation process, the preset period may also be set according to actual needs, and this embodiment is not limited herein.

Further, in this embodiment, when the designated detection time corresponding to different self-inspection devices is configured individually, the designated detection time may be set according to the working condition of the charging device, for example, if the detection is triggered by day, the working condition of the charging device in a week or a month is counted, the idle rate of the charging device in each time period in a day is determined, and then the time period with high idle rate is selected, and the failure processing method is triggered by setting the designated detection time in the time period with high idle rate, for example: the idle rate is higher in the early morning hours, and the specified detection time can be set in the early morning. Thus, the influence on the normal operation of the charging equipment can be reduced as much as possible. The specified detection time may be set by one or more of the periods, such as: the specified test times included monday through friday morning 7: 00 and 12:00 pm. In a specific implementation process, the specified detection time may be configured as needed, and the embodiment is not limited herein.

Further, in this embodiment, when the designated detection times corresponding to different self-inspection devices are configured in a unified manner, the designated detection times may be set according to the working conditions of the charging equipment of the whole network, for example, if the detection times are triggered by day, the working conditions of the charging equipment of the whole network in a week or a month are counted, the idle rate of the charging equipment of the whole network in each time period in a day is determined, and then the time period with the high idle rate is selected from the idle rate, and the time when the designated detection time is set in the time period with the high idle rate is used to trigger the fault handling method.

In a specific implementation process, the specified detection time may be configured as needed, and the embodiment is not limited herein.

And then, when the self-checking device determines that the corresponding charging equipment is in an idle state, the BMS module is controlled to be connected with the charging equipment, the charging equipment is detected aiming at the charging fault of the BMS module, and a detection result is obtained. The BMS module in the self-checking device can simulate a real vehicle, triggers the charging equipment to adopt a normal charging process to perform charging interaction with the charging equipment, so that the charging fault of the charging equipment when charging can be effectively detected when the charging equipment is in an idle state, and further, if the charging fault occurs, the charging fault is recorded, and fault information is uploaded to a fault processing server in time. The charging device can be used for effectively detecting the charging faults in idle time, the charging faults can be found in time, after the fault processing server is reported, the charging device with the faults can be repaired in time or cannot be pushed to a vehicle needing to be charged, and the situation that the residual electric quantity of the vehicle is wasted due to the fact that a user does not know the charging faults of the charging device is avoided.

Furthermore, after the self-checking device determines that the charging device is in the idle state, a fault of the charging device during charging is detected, in this embodiment, the charging fault during charging includes but is not limited to: low voltage power supply failure, BMS communication failure, insulation failure, contactor front end failure, contactor rear end failure, contactor adhesion failure, bleeder circuit failure, etc. In the following, the present embodiment sequentially explains the implementation manner of the above fault detection.

The first method comprises the following steps: and carrying out low-voltage power supply fault detection on the charging equipment to obtain a first detection result, wherein the method comprises the following steps: sending an auxiliary relay pull-in instruction to the charging equipment, so that after the charging equipment responds to the auxiliary relay pull-in instruction, a low-voltage auxiliary power supply and the BMS module form a communicated loop, detecting the output voltage of the low-voltage auxiliary power supply, judging whether the output voltage is preset voltage or not, and if not, indicating that the charging equipment has the low-voltage power supply fault according to a first detection result, wherein the low-voltage power supply fault is that the charging equipment cannot provide wake-up voltage for the BMS module.

Specifically, in this embodiment, the BMS module of the self-checking device is connected to the S + and S-ports of the charging device, respectively, S + is the charging communication high-bit data interface CAN-H in the charging device, and S-is the charging communication low-bit data interface CAN-L in the charging device. The BMS module is respectively connected with an A + port and an A-port of the charging equipment, wherein A + is the anode of the low-voltage auxiliary power supply of the charging equipment, and A-is the cathode of the low-voltage auxiliary power supply of the charging equipment. The low-voltage auxiliary power supply is used for providing a wake-up voltage for the BMS module of the charging vehicle, so that the BMS module of the charging vehicle can wake up and then can perform normal communication interaction based on the charging protocol with the charging equipment through lines connected with the S + and S-ports.

Therefore, the low-voltage power supply fault is a fault which needs to be detected firstly, and the follow-up fault can be effectively detected only by removing the fault.

Specifically, in the present embodiment, the failure of the contactor front end of the charging device refers to whether the supply voltage can be normally output to the front end of the contactor. When the front end fault of the contactor is detected, the self-detection device sends a front end fault detection instruction to the charging equipment, the charging equipment starts a front end fault detection circuit after responding to the instruction, the charging equipment outputs specified voltage, detects the front end voltage of the contactor, judges whether the front end voltage is larger than a first preset voltage or not, the first preset voltage can be set to be a value larger than 0 or equal to 0, if the front end voltage is larger than the first preset voltage, the voltage output by the power supply module can be normally output to the front end of the contactor, and a line between the power supply module and the contactor has no fault. On the contrary, if the front end voltage is smaller than or equal to the first preset voltage, the fact that the voltage output by the power supply module cannot be normally output to the front end of the contactor is shown, and a fault possibly exists in a line between the power supply module and the contactor, the fact that the fault exists at the front end of the contactor in the charging equipment is shown, and the fault information is recorded.

Specifically, in the present embodiment, the failure of the rear end of the contactor of the charging device refers to whether the supply voltage can be normally output to the rear end of the contactor with the contactor closed. When the rear end fault of the contactor is detected, the fact that the front end fault does not exist in the contactor is firstly determined, and the fact that the voltage of the power supply module can be normally output to the front end of the contactor is guaranteed.

Further, in this embodiment, if there is no front end fault or back end fault in the charging device, a contactor adhesion fault is also detected, where the contactor adhesion fault is that the charging device sends an adhesion or disconnection command to the contactor, and the contactor can normally respond to the commands. Specifically, the self-checking device sends a front-end fault detection instruction to the charging equipment, the charging equipment starts an adhesion fault detection circuit after responding to the instruction, when the contactor is determined to be in an adhesion state, the charging equipment sends a disconnection instruction to the contactor, then, the rear-end voltage is detected, whether the rear-end voltage is larger than 0 or not is judged, if the rear-end voltage is larger than 0, the contactor does not normally respond to the disconnection instruction and then is disconnected, and the contactor has adhesion faults.

In the specific implementation process, the charging fault may further include a blockage fault of a heat dissipation air port, an unlocking fault of an electromagnetic lock of the electric gun, and the like, and of course, other faults may also be included, and in the specific implementation process, the charging fault may be set according to actual needs, and here, the embodiment is not limited.

Furthermore, after charging faults existing in the charging equipment during charging are recorded, the recorded fault information is sent to the fault processing server, and meanwhile, the fault information can also be sent to any one or more combinations of the charging equipment, an output module of the self-checking device and a pile cloud server corresponding to the charging equipment.

Specifically, in this embodiment, effective output is required for the charging fault detected by the self-checking device, so that the charging user can timely acquire fault information, and waste of the remaining electric quantity of the vehicle is avoided. In addition, related faults of the charging equipment also need to be effectively fed back and reported to the fault processing server, and the faulty charging equipment can be timely overhauled through the fault processing server, so that reliable charging service is provided for users.

Through step S103, after receiving the detected fault information of the charging device reported by the self-detection apparatus, the fault processing server marks the state of the charging device as a fault state, so that when recommending a charging device to be selected from a normal charging device set for a user, the charging device is not in the normal charging device set.

Specifically, in this embodiment, the self-checking device is a third-party device independent of the charging device, the self-checking device is provided with a fault handling server for performing effective maintenance on a fault of the charging device, and the fault handling server is provided with a corresponding client, a charging user can register to the fault handling server in this embodiment through the client, the fault handling server can provide a charging device addressing service for the charging user, specifically, when the user needs to charge, the user sends a charging request to the fault handling server through the client, and the fault handling server can search the charging device in the vicinity of the charging user from the charging device in a normal state according to the location of the charging user and recommend the charging device to the charging user. In order to push the charging devices without faults for the user, the fault processing server maintains fault information of each charging device.

Each self-checking device is provided with a self-checking device identification, each self-checking device is also bound with a charging equipment identification corresponding to the charging equipment, and when the self-checking device uploads fault information, the self-checking device identification and the charging equipment identification of the charging equipment need to be uploaded together. And after receiving the fault information, the fault processing server stores the fault information to a storage space corresponding to the self-checking device identifier and the charging equipment identifier. And the state of the charging equipment is marked as a fault state, so that when the charging equipment to be selected is recommended to the user from the normal charging equipment set, the charging equipment is not in the normal charging equipment set, and the fault processing server does not push the charging equipment to the charging user.

Further, if the self-checking device detects that the fault repair of the charging equipment is completed, the normal state information of the charging equipment is sent to the fault processing server;

Further, after the charging equipment is repaired, the normal state information of the charging equipment can be sent to the self-checking device, the self-checking device sends the normal state information of the charging equipment to the fault processing server, or after the self-checking device triggers the fault processing method next time, if the fault information is not detected, the normal state information of the charging equipment can be actively sent to the fault processing server, and the fault processing server marks the state of the charging equipment as a normal state.

In this embodiment, step S103 may further include the following steps:

and sending the fault information to the target operation and maintenance user so that the target operation and maintenance user can maintain the charging equipment.

Specifically, in this embodiment, the fault processing server provides a client, and an owner user of the new energy charging vehicle can register to the fault processing server through the client, and an operation and maintenance user of the charging device can also register through the installed client. Therefore, a plurality of operation and maintenance users are registered in the fault processing server, and a target operation and maintenance user can be selected from all the operation and maintenance users to timely maintain the charging equipment in the fault state.

The target operation and maintenance user can be determined in the following ways:

the first method for determining the target operation and maintenance user based on the distance comprises the following steps: determining a target position of the charging equipment; and determining a target operation and maintenance user closest to the target position from the at least one operation and maintenance user.

Specifically, in this embodiment, each self-checking device corresponds to a self-checking device identifier, a charging device identifier is bound to each self-checking device identifier, the fault handling server can communicate with the pile cloud servers of the manufacturers, and sends the charging device identifier to the pile cloud server to which the charging device belongs, so that the pile cloud server maintains the position information of each charging device to which the pile cloud server belongs, the pile cloud server can query the target position of the corresponding charging device based on the received charging device identifier and send the target position to the fault handling server, and the fault handling server can call the position information of each operation and maintenance user based on the target position to obtain the target operation and maintenance user closest to the target position. Therefore, the fault processing server can send the fault information and the target position of the charging equipment to the target operation and maintenance user, and the target operation and maintenance user can timely arrive at the target position to maintain the charging equipment.

Secondly, determining a target operation and maintenance user based on the fault type, comprising: determining a target fault type to which the fault information belongs; and determining a target operation and maintenance user matched with the target fault type from at least one operation and maintenance user.

Specifically, in the foregoing embodiment, since the charging failure includes different types, it is not limited to the foregoing seven types of failures. The fault types of different operation and maintenance users who are good at maintaining are different, the operation and maintenance users can add the fault types of the operation and maintenance users who are good at maintaining through the client, and the fault processing server records the fault types of the operation and maintenance users who are good at maintaining. And further, matching the target operation and maintenance user with the highest matching degree with the fault type of the charging equipment for the charging equipment with the fault. For example, if the fault information indicates that the charging device has a fault a and a fault B, an operation and maintenance user who excels in maintaining the fault a and the fault B is determined from all operation and maintenance users, and if a plurality of such operation and maintenance users exist, one operation and maintenance user can be randomly selected as a target operation and maintenance user. Or selecting the current working state as idle as the target operation and maintenance user. Or selecting the user closest to the charging equipment as the target operation and maintenance user.

Thirdly, determining a target operation and maintenance user based on the binding relationship.

Specifically, in this embodiment, the charging device may be divided into areas, and each area is bound with a corresponding operation and maintenance user. After the fault processing server receives the fault information of the charging equipment, the area to which the charging equipment belongs can be determined, and the operation and maintenance user corresponding to the area to which the charging equipment belongs is determined as the target operation and maintenance user according to the area to which the charging equipment belongs. Or, for each charging device, an operation and maintenance user corresponding to the charging device is distributed. In this way, after the fault processing server receives the fault information of the charging device, the operation and maintenance user allocated to the charging device can be determined as the target operation and maintenance user. Therefore, the fault processing server can send the fault information and the target position of the charging equipment to the target operation and maintenance user, and the target operation and maintenance user can timely arrive at the target position to maintain the charging equipment.

Furthermore, after the charging equipment is maintained and recovered to be normal, the charging equipment can send the information of the normal state of the charging equipment to the self-checking device in time, the self-checking device can report the information of the normal state of the charging equipment to the fault processing server in time, and the fault processing server can correct the state of the charging equipment in time, so that the charging equipment can be put into use in time, and more charging users of the charging equipment accessory can charge in time.

In a specific implementation process, the target operation and maintenance user may also be determined in other manners, and may be set according to actual needs, where this embodiment is not limited.

Further, in this embodiment, after receiving the failure information, the failure processing server sends the charging device in the failure state to the charging user associated with the charging device.

Specifically, in this embodiment, the fault handling server sends a historical charging record query instruction to the pile cloud server corresponding to the charging device, and the pile cloud server feeds back the charging users who have been charged in the charging device in the recent period (for example, within one month, within a half year, and the like) according to the historical charging record query instruction, and then the fault handling server takes the charging users who have been charged more than a preset number of times as the charging users associated with the charging device, or selects the charging users who have been charged with the first N times as the charging users associated with the charging device. In a specific implementation process, the preset charging number and the value of N may be set according to actual needs, and this embodiment is not limited herein. After the associated charging user is determined, the charging equipment can be sent to the charging user associated with the charging equipment in a fault state. In a specific implementation process, the associated charging user may set according to actual needs, and this embodiment is not limited herein.

Further, in this embodiment, the fault information recorded by the self-checking device may be transmitted to the charging device in addition to being uploaded to the fault processing server, and the charging device is provided with a corresponding output module, or the recorded fault information may be transmitted to the output module in the self-checking device, and the fault information is output through the output module, so that a relevant maintenance worker of the charging device can find the fault information of the charging device in time in the patrol process. The output module may be a display screen, an audio output device, or the like, and may be configured according to actual needs in a specific implementation process, where this embodiment is not limited.

In this embodiment, after receiving the fault information sent by the self-checking device, the charging device uploads the fault information of the charging device to the pile cloud server to which the charging device belongs. Or the self-checking device directly sends the fault information of the charging equipment to the pile cloud server to which the charging equipment belongs, and the pile cloud server does not push the charging equipment to a user when searching for available charging equipment for the user. And the pile cloud server can acquire the operation and maintenance user bound by the charging equipment through the identification information of the charging equipment and inform the operation and maintenance user of effectively overhauling the charging equipment. Or the position information of the charging equipment is obtained, the operation and maintenance user closest to the charging equipment is inquired, and the operation and maintenance user is informed to carry out effective maintenance on the charging equipment.

In a specific implementation process, the processing manner of the fault information by the fault processing server is not limited to the above several manners, and in the specific implementation process, the setting may be performed according to actual needs, and here, the embodiment is not limited.
