Especially in the home plug-and-charge environment, some occasional faults will cause the charging to be interrupted. At this time, if there is no one on site to perform the plugging and unplugging operation, the fault cannot be recovered, which will cause the charging pile to be unable to charge the vehicle normally, bringing great inconvenience to users. Therefore, improvement is needed. Summary of the Invention

[0003] To facilitate the fault recovery of the charging pile, this application provides a method for self-recovery of charging pile faults, a charging adapter, and a device.

[0004] In a first aspect, this application provides a method for self-recovery of charging pile faults, adopting the following technical solution:

[0005] A method for self-recovery of charging pile faults, the method comprising:

[0006] In response to a fault instruction, control the self-recovery relay to disconnect, so as to disconnect the connection of the guiding control line between the charging gun of the charging pile and the vehicle end, and the self-recovery relay is used to connect the guiding control line of the charging gun and the vehicle end;

[0007] Monitor whether the re-closure condition is met;

[0008] When it is monitored that the re-closure condition is met, control the self-recovery relay to close, so as to re-establish the connection of the guiding control line between the charging gun and the vehicle end.

[0009] By adopting the above technical solution, it is possible to simulate the plugging and unplugging of the gun by controlling the self-recovery relay without actually performing the plugging and unplugging operation of the gun, thereby helping to achieve automatic fault handling and further improving the user experience.

[0010] Optionally, the method further comprises:

[0011] When the charging gun is connected to the vehicle end, monitor the state of the guiding control line;

[0012] When it is monitored that the continuous duration of the guiding control line in the first state exceeds the first duration threshold, generate the fault instruction;

[0013] When the duration that the guiding control line is in the second state but without current exceeds the second duration threshold, generate the fault instruction, where the second state is different from the first state.

[0014] By adopting the above technical solution, the fault instruction can be automatically generated, so that the automatic judgment and recovery of faults can be realized without the need for the user to perform corresponding operations, thereby helping to improve the user's charging experience.

[0015] Optionally, after generating the fault instruction, it further includes:

[0016] Obtain the electrical output parameters of the charging gun;

[0017] Determine the fault type based on the electrical output parameters and the state of the guiding control line;

[0018] Output a fault prompt message based on the fault type.

[0019] By adopting the above technical solution, a fault prompt message can be output in combination with the fault type while automatically processing the fault to indicate that a fault occurs during the charging process, so as to facilitate the user and the management personnel to understand the abnormality of the charging process.

[0020] Optionally, the first state includes a third state and a fourth state, and determining the fault type based on the electrical output parameters and the state of the guiding control line includes:

[0021] When the guiding control line is in the third state, or when the guiding control line is in the second state and the electrical output parameters indicate no voltage, determine that the fault type is that the charging pile has not started;

[0022] When the guiding control line is in the fourth state, or when the guiding control line is in the second state and the electrical output parameters indicate voltage, determine that the fault type is that the vehicle end does not accept charging.

[0023] By adopting the above technical solution, the specific fault type can be determined by combining the state of the guiding control line and the voltage condition indicated by the electrical output parameters.

[0024] Optionally, responding to the fault instruction to control the self - recovery relay to disconnect includes:

[0025] Responding to the fault instruction, determine whether the interval duration since the last time the self - recovery relay was controlled to close is less than the interval duration threshold;

[0026] When the interval duration is greater than or equal to the interval duration threshold, control the self - recovery relay to disconnect;

[0027] When the interval duration is less than the interval duration threshold, monitor the interval duration, and when it is detected that the interval duration reaches the interval duration threshold, control the self - reset relay to open.

[0028] By adopting the above - mentioned technical solution, when a fault instruction is received, it is possible to further determine the relationship between the interval duration since the last control of the self - reset relay to close and the interval duration threshold to determine whether to control the self - reset relay to open. In this way, there can be a certain time interval between the closing and opening of the self - reset relay, which can help avoid damage to the self - reset relay caused by frequent opening and closing.

[0029] Optionally, the controlling the self - reset relay to open when it is detected that the interval duration reaches the interval duration threshold includes:

[0030] When it is detected that the interval duration reaches the interval duration threshold, verify whether the current state meets the execution condition;

[0031] When the current state meets the execution condition, control the self - reset relay to open;

[0032] When the current state does not meet the execution condition, do not control the self - reset relay to open.

[0033] By adopting the above - mentioned technical solution, in the case of not immediately responding to the recovery instruction, it will further determine whether it is necessary to control the self - reset relay to open under the current conditions, which can help avoid unnecessary opening of the self - reset relay.

[0034] Optionally, the monitoring whether the re - closing condition is met includes:

[0035] Determine whether the waiting duration reaches the waiting duration threshold, where the waiting duration starts to be calculated after the self - reset relay is controlled to open;

[0036] When the waiting duration reaches the waiting duration threshold, determine that the re - closing condition is met.

[0037] By adopting the above - mentioned technical solution, the time interval between the disconnection and re - closing of the self - reset relay can be controlled by setting the waiting duration threshold. In this way, a duration for the charging pile to respond to the guiding control signal can be reserved, so as to ensure that the charging pile can respond to the disconnection of the guiding control line, and further ensure the generation of the effect of simulated plugging and unplugging.

[0038] Optionally, the determining that the re - closing condition is met when the waiting duration reaches the waiting duration threshold includes:

[0039] When the waiting duration reaches the waiting duration threshold, determine whether the connection between the charging gun and the vehicle end is disconnected;

[0041] Based on the status data, determine whether the charging pile meets the reconnection condition;

[0042] When it is determined that the charging pile does not meet the reconnection condition, send a reconnection instruction to the charging pile;

[0043] When it is determined that the charging pile meets the reconnection condition, determine that the re - closing condition is met.

[0044] By adopting the above - mentioned technical solution, when the waiting duration reaches the waiting duration threshold and the charging gun is not disconnected from the vehicle end, the status data of the charging pile will be further obtained, and when it is determined based on the status data that the charging pile meets the reconnection condition, it is determined that the re - closing condition is met. In this way, it can help improve the safety of the re - closing process and reduce the probability of safety risks.

[0063] In order to make the objectives, technical solutions and advantages of the present application clearer, the following further describes the present application in detail with reference to the appended Figures 1-7 embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0064] An embodiment of the present application discloses a method for self - recovery of charging pile faults. Referring to Figure 1 , the method for self - recovery of charging pile faults includes the following steps:

[0065] Step 101, in response to a fault instruction, control the self - restoring relay to disconnect to disconnect the connection of the guiding control line between the charging gun of the charging pile and the vehicle end.

[0066] Among them, the fault instruction is used to indicate the disconnection of the self - restoring relay. In one example, the fault instruction is automatically generated when an abnormal working state of the charging pile is detected. For example, it is automatically generated when an abnormal signal state of the pilot control line (CP line) is detected, or it can also be generated when the reset control is triggered. For example, it is generated when the user triggers the reset control installed on the adapter or the charging gun. Or it can also be sent by the background. This embodiment does not limit the generation method of the fault instruction.

[0067] The self - restoring relay is used to connect the charging gun and the pilot control line at the vehicle end. Specifically, the self - restoring relay is in a normally - closed state. At this time, when the charging gun is connected to the vehicle end, the connection of the pilot control line between the charging gun and the vehicle end is in a conducting state, and signal interaction can be carried out between the charging gun and the vehicle end through the pilot control line. In the case where the self - restoring relay is disconnected, the connection of the pilot control line between the charging gun and the vehicle end is in a disconnected state, and signal interaction cannot be carried out between the charging gun and the vehicle end through the pilot control line.

[0068] It should be added that the self - restoring relay is only used to control the possibility of connecting the pilot control line between the charging gun and the vehicle end. Whether signal interaction can be carried out between the charging gun and the vehicle end through the pilot control line also depends on factors such as whether the charging gun is connected to the vehicle end. However, when the self - restoring relay is in a disconnected state, signal interaction cannot be carried out between the charging pile and the vehicle end through the pilot control line.

[0069] In one example, the self - restoring relay can be set in the charging adapter. The charging adapter includes a first connection end for connecting the charging gun and a second connection end for connecting the vehicle end. Correspondingly, the self - restoring relay is used to control the conduction and disconnection of the pilot control line connector at the first connection end and the pilot control line connector at the second connection end. In actual implementation, the self - restoring relay can also be integrated in the charging gun, as long as the corresponding functions can be achieved. This embodiment does not limit the setting method of the self - restoring relay.

[0070] Step 102, monitor whether the re - closing condition is met.

[0071] Among them, the re - closing condition refers to the condition for closing the self - restoring relay. Specifically, in this embodiment, the disconnection of the self - restoring relay can cut off the connection of the pilot control line between the charging gun and the vehicle end, thereby simulating the unplugging operation. In order to achieve self - recovery of the fault, it is also necessary to simulate the plugging operation. Therefore, it is necessary to achieve the automatic closing of the recovery relay. Before closing the self - restoring relay, it is necessary to determine whether the re - closing condition is met.

[0072] In one example, the re - closing condition can be determined in combination with at least one of factors such as the duration since the self - restoring relay is disconnected, the connection status between the charging gun and the vehicle end, the status of the charging pile, and the status of the vehicle end. For example, the re - closing condition includes that the duration since the self - restoring relay is disconnected reaches a waiting duration threshold.

[0073] In another example, the re - closing condition includes that the number of disconnections of the self - restoring relay during the current charging process is less than a preset disconnection number threshold. That is, when the number of disconnections of the self - restoring relay during the current charging process is greater than or equal to the preset disconnection number threshold, it is determined that the re - closing condition is not satisfied, and a fault alarm message is output. This can help avoid damage to the self - restoring relay caused by frequent disconnections and closures.

[0074] Step 103, when it is monitored that the re - closing condition is satisfied, control the self - restoring relay to close to re - establish the connection of the guiding control line between the charging gun and the vehicle end.

[0075] Specifically, the closed - loop of the self - restoring relay can make the guiding control line between the charging gun and the vehicle end conduct again, thereby simulating the gun - inserting operation.

[0076] Optionally, when it is not monitored that the re - closing condition is satisfied within a preset monitoring duration, end the monitoring and output a charging abnormality prompt message. For example, when the connection between the charger and the vehicle end is disconnected, a connection - disconnected prompt message can be output.

[0077] The implementation principle of a charging pile fault self - recovery method in an embodiment of the present application is as follows: In response to a fault instruction, control the self - restoring relay to disconnect to disconnect the connection of the guiding control line between the charging gun of the charging pile and the vehicle end. The self - restoring relay is used to connect the guiding control line of the charging gun and the vehicle end; monitor whether the re - closing condition is satisfied; when it is monitored that the re - closing condition is satisfied, control the self - restoring relay to close to re - establish the connection of the guiding control line between the charging gun and the vehicle end. By adopting the above technical solution, in response to a fault instruction, the self - restoring relay can be controlled to disconnect to simulate the gun - unplugging operation, and when it is monitored that the re - closing condition is satisfied, the self - restoring relay can be controlled to close to simulate the gun - inserting operation. In this way, the simulation of plugging and unplugging the gun can be realized by controlling the self - restoring relay without actually performing the plugging and unplugging gun operations, which can help achieve automatic fault handling and improve the user experience.

[0078] In some embodiments, referring to Figure 2 , the charging pile fault self - recovery method provided in this embodiment further includes the following steps:

[0079] Step 201, when the charging gun is connected to the vehicle end, monitor the status of the guiding control line.

[0080] Specifically, the control pilot line (CP line) plays an important role in the AC charging line. It is a signal line responsible for the state synchronization between the vehicle and the charging pile. In the AC slow charging system of electric vehicles, the CP line is mainly used to transmit control pilot function signals. In actual implementation, the working state of the charging pile can be determined according to the level state of the CP line, such as: standby state, charging state, etc.

[0081] In one example, a self - reset relay is set in the charging adapter. At this time, the charging gun is connected to the vehicle end through the charging adapter. Correspondingly, the state of the control pilot line can be monitored through the charging adapter.

[0082] In another example, a self - reset relay is integrated in the charging gun. At this time, the charging gun is directly connected to the vehicle end. Correspondingly, the state of the control pilot line can be monitored through the charging pile.

[0083] Step 202: Generate a fault instruction when it is monitored that the continuous duration of the control pilot line in the first state exceeds the first duration threshold.

[0084] Among them, the first state is the standby state for charging. During normal charging, the control pilot line will not be in the first state for a long time.

[0085] Optionally, the first state includes the semi - connected (B1) state, the ready - to - charge (B2) state, and / or the fully - connected (C2) state.

[0086] In actual implementation, the first duration threshold can be set according to the actual situation. For example, the first duration threshold is 1 minute. Further, when the first state includes multiple states, the first duration thresholds corresponding to different first states can be the same or different.

[0087] Step 203: Generate a fault instruction when it is monitored that the duration of the control pilot line in the second state but without current exceeds the second duration threshold.

[0088] Among them, the second state is different from the first state, and the second state is used to indicate that charging is in progress. In one example, the second state includes the charging (C2) state.

[0089] In actual implementation, the second duration threshold can be set according to actual needs. For example, the second duration threshold can be 2 minutes.

[0090] In the above technical solution, when the charging pile is connected to the vehicle end, the state of the guiding control line can be monitored, and abnormal judgment can be made based on the abnormal judgment conditions corresponding to different states, so as to automatically generate a fault instruction when an abnormality is detected. In this way, automatic judgment and recovery of faults can be realized without the user performing corresponding operations, thereby helping to improve the user's charging experience.

[0091] Further, referring to Figure 3 , after generating the fault instruction in step 202 or step 203, the following steps are further included:

[0092] Step 301, obtain the electrical output parameters of the charging gun.

[0093] Among them, the electrical output parameters are used to indicate the electrical output situation of the charging gun, such as whether there is voltage. Specifically, the electrical output parameters can be collected through a sensing component. For example, the electrical output parameters of the charging gun can be collected through a sensing component set in the charging adapter, or they can also be obtained from the charging pile system or the operation and maintenance background.

[0094] Step 302, determine the fault type based on the electrical output parameters and the state of the guiding control line.

[0095] Optionally, the fault types include that the charging pile fails to start and the vehicle end is not powered.

[0096] In an example, determining the fault type based on the electrical output parameters and the state of the guiding control line includes: when the guiding control line is in the second state and the electrical output parameters indicate no voltage, determining that the fault type is that the charging pile fails to start; when the guiding control line is in the second state and the electrical output parameters indicate voltage, determining that the fault type is that the vehicle end is not powered.

[0097] Specifically, when an abnormality occurs when the control guiding line is in the second state, that is, there is no current during charging. The reasons for this situation may be that the charging pile fails to start or the vehicle end is not powered. Based on this, in the above technical solution, it is further determined whether there is voltage based on the electrical output parameters, and the fault type is finally determined in combination with whether there is voltage.

[0098] Further, when the guiding control line is in the second state and the electrical output parameters indicate voltage, determining that the fault type is that the vehicle end is not powered includes: when the guiding control line is in the second state and the electrical output parameters indicate voltage, determining whether the voltage is greater than or equal to a preset voltage threshold; when the voltage is greater than or equal to the voltage threshold, determining that the fault type is that the vehicle end is not powered; when the voltage is less than the voltage threshold, determining that the fault type is insufficient voltage of the charging pile.

[0099] In another example, the first state includes a third state and a fourth state. Correspondingly, determining the fault type based on the electrical output parameter and the state of the guiding control line includes: when the guiding control line is in the third state, determining that the fault type is that the charging pile has not started; when the guiding control line is in the fourth state, determining that the vehicle end is not powered.

[0100] Among them, the third charging state is the pre-charging state related to the charging pile, such as: semi-connected (B1) state and ready to charge (B2) state. The fourth charging state is the pre-charging state related to the vehicle end, such as: fully connected (C1) state.

[0101] Step 303, output a fault prompt message based on the fault type.

[0102] Among them, the fault prompt messages corresponding to different fault types are different, so that the fault type can be identified based on the fault prompt message.

[0103] Optionally, the fault prompt message can be output through a buzzer or an indicator light set on the charging pile, or can also be output through the information displayed on the background or the user terminal. This embodiment does not limit the output method of the fault prompt message.

[0104] In the above embodiment, after generating the fault instruction, the fault type can be determined based on the point output parameter of the charging gun and the state of the guiding control line, and the abnormal prompt message corresponding to the fault type is output. In this way, the fault prompt message can be output while automatically processing the fault to prompt that a fault occurs during the charging process, so as to facilitate users and managers to understand the abnormality of the charging process.

[0105] In some embodiments, referring to Figure 4 , step 101, in response to the fault instruction, controlling the self-resetting relay to disconnect, includes the following steps:

[0106] Step 401, in response to the fault instruction, determine whether the interval duration since the last time the self-resetting relay was closed is less than the interval duration threshold.

[0107] In one example, the interval duration threshold is fixedly set, for example: the interval duration threshold is 10 minutes.

[0108] In another example, the interval duration threshold is determined based on the number of disconnections of the self-resetting relay during the current charging process, for example: the more the number of disconnections, the shorter the interval duration.

[0109] Step 402, when the interval duration is greater than or equal to the interval duration threshold, control the self-resetting relay to disconnect.

[0110] Step 403, when the interval duration is less than the interval duration threshold, monitor the interval duration, and when it is detected that the interval duration reaches the interval duration threshold, control the self - reset relay to disconnect.

[0111] Optionally, when it is detected that the interval duration reaches the interval duration threshold, controlling the self - reset relay to disconnect includes: when it is detected that the interval duration reaches the interval duration threshold, verifying whether the current state meets the execution condition; when the current state meets the execution condition, controlling the self - reset relay to disconnect; when the current state does not meet the execution condition, not controlling the self - reset relay to disconnect.

[0112] Specifically, during the process of waiting for the interval duration to reach the interval duration threshold, the charging state may change. For example, it may change from a fault state to a normal state. In this case, there is no need to perform the simulated plug - and - unplug gun operation, that is, there is no need to control the self - reset relay to disconnect and close. Therefore, when the recovery instruction is not immediately responded to, it will further determine whether it is necessary to control the self - reset relay to disconnect under the current conditions, which can help avoid unnecessary disconnection of the self - reset relay.

[0113] In one example, the execution condition includes a fault in the charging process. At this time, verifying whether the current state meets the execution condition includes: determining whether there is a fault in the charging process; when there is a fault in the charging process, determining that the execution verification condition is met; when there is no fault in the charging process, determining that the execution verification condition is not met.

[0114] Among them, the method of determining whether there is a fault in the charging process can be analogous to the generation conditions of the fault instruction in steps 201 to 203.

[0115] Further, before determining whether the self - reset relay has a fault, it includes: determining whether the fault instruction is automatically generated when a fault is detected; if so, performing the step of determining whether the self - reset relay has a fault; if not, it can perform the determination of meeting the verification condition, or it can also determine whether the verification condition is met based on other methods.

[0116] Correspondingly, the fault instruction can be automatically generated when a fault is detected, or it can also be generated when the reset control is triggered.

[0117] In the above technical solution, when a fault instruction is received, it will further determine the relationship between the interval duration since the last time the self - reset relay was controlled to close and the interval duration threshold to determine whether to control the self - reset relay to disconnect. This can ensure that there is a certain time interval between the closing and disconnecting of the self - reset relay, thus helping to avoid damage to the self - reset relay caused by frequent disconnection and closing.

[0118] In some embodiments, step 102 of monitoring whether the re - closing condition is met includes: determining whether the waiting duration has reached the waiting - duration threshold; and in the case where the waiting duration has reached the waiting - duration threshold, determining that the re - closing condition is met.

[0119] Among them, the waiting duration is calculated since the self - recovery relay is disconnected. Specifically, the waiting duration can be fixedly set. For example, the waiting duration is 10S, or it can also be dynamically determined. For example, it is determined in combination with the number of disconnections during the current charging process. The greater the number of disconnections, the longer the waiting duration, and the waiting durations corresponding to different numbers of disconnections can be determined in advance.

[0120] In the above - mentioned embodiments, by setting the waiting - duration threshold, the time interval between the disconnection and the re - closing of the self - recovery relay can be controlled. In this way, a duration can be reserved for the charging pile to respond to the guiding control signal, thereby ensuring that the charging pile can respond to the disconnection of the guiding control line, and further ensuring the effect of simulating plug - unplugging.

[0121] Based on the above - mentioned embodiments, further, in the case where the waiting duration has reached the waiting - duration threshold, determining that the re - closing condition is met includes the following steps:

[0122] Step 501, in the case where the waiting duration has reached the waiting - duration threshold, determine whether the connection between the charging gun and the vehicle end is disconnected.

[0123] In one example, the self - recovery relay is set in the charging adapter. At this time, the charging gun is connected to the vehicle end through the charging adapter. Correspondingly, it can be determined whether the connection between the charging gun and the vehicle end is disconnected based on the connection relationship between the charging adapter, the charging gun, and the vehicle end. For example, induction components are respectively set at the interfaces of the charging adapter with the charging gun and the vehicle end to respectively detect whether the charging gun and the vehicle end are connected.

[0124] In another example, the self - recovery relay is integrated in the charging gun. At this time, the charging gun is directly connected to the vehicle end. Correspondingly, it can be directly monitored whether the connection between the charging gun and the vehicle end is disconnected. For example, an induction component is set at the interface of the charging gun muzzle to sense whether the charging gun is inserted into the vehicle end.

[0125] Step 502, in the case where the connection between the charging gun and the vehicle end is not disconnected, obtain the status data of the charging pile.

[0126] Among them, the status data of the charging pile is used to indicate the status of the charging pile. Specifically, the status data of the charging pile is recorded by the charging pile. Further, the charging pile uploads the status data to the charging - pile management system based on the communication connection between the charging - pile management systems.

[0127] Optionally, when the connection between the charging gun and the vehicle end is disconnected, it is determined that the reconnection condition is not met, and a connection disconnection prompt message is output to indicate that the connection between the charging gun and the vehicle end is disconnected. Further, when it is detected within a preset verification duration after the connection disconnection prompt message is output that the connection between the charging gun and the vehicle end is restored, the status data of the charging pile can be obtained, and steps 503 to 505 can be executed.

[0128] In one example, the self - restoring relay is set in the charging adapter. At this time, the charging adapter can obtain the status data of the charging pile based on the communication connection with the charging pile or the communication connection with the charging pile management system.

[0129] In another example, the self - restoring relay is integrated in the charging gun, and the status data of the charging pile can be directly obtained here.

[0130] Step 503: Determine whether the charging pile meets the reconnection condition based on the status data.

[0131] In one example, the reconnection condition includes that the charging pile is in a ready - to - supply power state. Specifically, before being enabled, the charging pile is in a standby state. The user needs to create a charging order by swiping a card, scanning a code, etc. After the charging pile receives the charging order information, it will switch to the ready - to - supply power state to supply power to the vehicle end.

[0132] Correspondingly, determining whether the charging pile meets the reconnection condition based on the status data includes: determining whether the charging pile is in a ready - to - supply power state; if so, determining that the charging pile meets the reconnection condition; if not, determining that the charging pile does not meet the reconnection condition.

[0133] In another example, the reconnection condition includes that the charging pile prompts to connect the vehicle end. Specifically, under normal circumstances, when the charging pile detects an interruption of the guiding control signal, it will determine that the vehicle end is disconnected and output a prompt message to connect the vehicle end.

[0134] Correspondingly, determining whether the charging pile meets the reconnection condition based on the status data includes: determining whether the charging pile prompts to connect the vehicle end; if so, determining that the charging pile meets the reconnection condition; if not, determining that the charging pile does not meet the reconnection condition.

[0135] In other examples, the reconnection condition includes that there is no output current and output voltage from the charging gun. Specifically, since controlling the self - restoring relay to close indicates an operation of simulating unplugging the gun, although the charging gun is not disconnected from the vehicle end, there may be abnormal situations where there is still current and voltage output. At this time, corresponding processing is required to ensure the safety of the reconnection process.

[0136] Step 504: When it is determined that the charging pile does not meet the reconnection condition, send a reconnection instruction to the charging pile.

[0137] Among them, the reconnect instruction is used to instruct the charging pile to adjust the status data to meet the reconnect condition. Specifically, the reconnect instruction can be sent directly to the charging pile, or it can also be sent to the charging pile through the charging pile management system.

[0138] Correspondingly, under normal circumstances, the charging pile will adjust its status in response to the reconnect instruction so that the status data meets the reconnect condition.

[0139] Optionally, after sending the reconnect instruction to the charging pile, it further includes: after a preset adjustment duration threshold, re-obtaining the status data of the charging pile, and returning to execute step 503 to determine whether the charging pile meets the reconnect condition based on the status data.

[0140] Step 505, when it is determined that the charging pile meets the reconnect condition, determine that the re-closure condition is met.

[0141] In the above technical solution, when the waiting duration reaches the waiting duration threshold and the charging gun is not disconnected from the vehicle end, the status data of the charging pile will be further obtained, and when it is determined that the charging pile meets the reconnect condition based on the status data, it is determined that the re-closure condition is met. This can help improve the safety of the re-closure process and reduce the probability of safety risks.

[0142] The embodiment of the present application also provides a charging adapter, referring to Figure 6 , the charging adapter includes a first connection end 610, a second connection end 620, a self-resetting relay 630, and a controller 640 connected to the self-resetting relay 630; the first connection end 610 is used to connect the charging gun, the second connection end 620 is used to connect the vehicle end, and the self-resetting relay 630 is used to control the conduction and disconnection of the guiding control line connector of the first connection end 610 and the guiding control line connector of the second connection end 620.
