[0002] At present, it is very inconvenient to plug and unplug the gun of the charging pile, and some fault handling requires pulling out the gun, especially in the home plug-and-charge environment. Some occasional faults will interrupt the charging. At this time, if there is no one on site to perform the plug-in and unplug operation, the fault cannot be recovered. This will cause the charging pile to be unable to charge the vehicle normally, which brings great inconvenience to the user, so it needs to be improved. Summary of the invention

[0003] In order to help recover from charging pile faults, the present application provides a charging pile fault self-recovery method, a charging adapter and equipment.

[0004] In the first aspect, the present application provides a charging pile fault self-recovery method, which adopts the following technical solution: A charging pile fault self-recovery method, the method comprising: In response to the fault instruction, the self-recovery relay is controlled to be disconnected to disconnect the connection of the guide control line between the charging gun of the charging pile and the vehicle end, and the self-recovery relay is used to connect the guide control line between the charging gun and the vehicle end; Monitor whether reclosing conditions are met; When it is monitored that the reclosing condition is met, the self-resetting relay is controlled to close so as to re-establish the connection of the guide control line between the charging gun and the vehicle end.

[0005] By adopting the above technical solution, the plug-in and pull-out of the gun can be simulated by controlling the self-resetting relay without actually plugging and pulling the gun, which can help to realize automatic fault processing and further help to improve the user experience.

[0006] Optionally, the method further includes: When the charging gun is connected to the vehicle end, monitoring the state of the guide control line; generating the fault instruction when it is detected that the continuous time duration of the guide control line being in the first state exceeds a first time duration threshold; The fault instruction is generated when it is monitored that the pilot control line is in a second state but has no current for a period exceeding a second time threshold, the second state being different from the first state.

[0007] By adopting the above technical solution, a fault instruction can be automatically generated, so that automatic fault judgment and recovery can be achieved without the user having to perform corresponding operations, which can help improve the user's charging experience.

[0008] Optionally, after generating the fault instruction, the method further includes: Get the electrical output parameters of the charging gun; determining a fault type based on the electrical output parameter and a state of the pilot control line; Fault prompt information is output based on the fault type.

[0009] By adopting the above technical solution, the fault can be automatically processed and the fault prompt information can be output in combination with the fault type to indicate that a fault has occurred during the charging process, thereby making it easier for users and managers to understand the abnormality of the charging process.

[0010] Optionally, the first state includes a third state and a fourth state, and the electrical output parameter and the state of the guide control line determine the fault type, including: When the guide control line is in the third state, or the guide control line is in the second state and the electrical output parameter indicates that there is no voltage, determining that the fault type is that the charging pile is not started; When the guide control line is in the fourth state, or the guide control line is in the second state and the electrical output parameter indicates that there is voltage, it is determined that the fault type is that the vehicle end does not accept charging.

[0011] By adopting the above technical solution, the specific fault type can be determined in combination with the state of the guide control line and the voltage condition indicated by the electrical output parameter.

[0012] Optionally, in response to the fault instruction, controlling the self-recovery relay to disconnect includes: In response to the fault instruction, determining whether the interval time since the last time the self-restoring relay was controlled to be closed is less than an interval time threshold; When the interval duration is greater than or equal to the interval duration threshold, controlling the self-resetting relay to disconnect; When the interval duration is less than the interval duration threshold, the interval duration is monitored, and when it is monitored that the interval duration reaches the interval duration threshold, the self-resetting relay is controlled to be disconnected.

[0013] By adopting the above-mentioned technical scheme, when a fault instruction is received, the relationship between the interval time from the last time the self-recovery relay was controlled to close and the interval time threshold can be further determined to determine whether to control the self-recovery relay to disconnect. In this way, there can be a certain time interval between the closing and disconnecting of the self-recovery relay, which can help avoid damage to the self-recovery relay due to frequent disconnection and closing.

[0014] Optionally, when it is monitored that the interval duration reaches the interval duration threshold, controlling the self-recovery relay to disconnect includes: In the case where it is monitored that the interval duration reaches the interval duration threshold, checking whether the current state satisfies the execution condition; When the current state satisfies the execution condition, controlling the self-resetting relay to disconnect; When the current state does not satisfy the execution condition, the self-resetting relay is not controlled to be disconnected.

[0015] By adopting the above technical solution, when there is no immediate response to the recovery instruction, it will be further determined whether it is necessary to control the self-recovery relay to disconnect under the current conditions, which can help avoid unnecessary disconnection of the self-recovery relay.

[0016] Optionally, the monitoring whether the reclosing condition is met includes: Determine whether the waiting time reaches a waiting time threshold, wherein the waiting time is calculated from the time when the self-recovery relay is controlled to be disconnected; When the waiting time reaches the waiting time threshold, it is determined that the reclosing condition is met.

[0017] By adopting the above technical solution, the time interval between the time of reopening after the self-recovery relay is disconnected can be controlled by setting a waiting time threshold. In this way, the time for the guidance control signal to react can be reserved for the charging pile, thereby ensuring that the charging pile can respond to the disconnection of the guidance control line, and further ensuring the effect of simulating plugging and unplugging.

[0018] Optionally, when the waiting time reaches the waiting time threshold, determining that the reclosing condition is satisfied includes: When the waiting time reaches a waiting time threshold, determining whether the connection between the charging gun and the vehicle end is disconnected; When the connection between the charging gun and the vehicle end is not disconnected, obtaining the status data of the charging pile; Determining whether the charging pile meets a reconnection condition based on the status data; When it is determined that the charging pile does not meet the reconnection condition, sending a reconnection instruction to the charging pile; In the case where it is determined that the charging pile meets the reconnection condition, it is determined that the reclosing condition is met.

[0019] By adopting the above technical solution, when the waiting time reaches the waiting time threshold and the charging gun is not disconnected from the vehicle, the status data of the charging pile will be further obtained, and based on the status data, it is determined that the charging pile meets the reconnection conditions and the reclosing conditions are met. This can help improve the safety of the reclosing process and reduce the probability of safety risks.

DETAILED DESCRIPTION

[0024] In order to make the purpose, technical solutions and advantages of this application more clear, the following Figure 1-7 The present application is further described in detail in the following 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.

[0025] The present application embodiment discloses a charging pile fault self-recovery method. Figure 1 , the charging pile fault self-recovery method includes the following steps: Step 101, in response to a fault instruction, control the self-recovery relay to disconnect, so as to disconnect the connection of the guide control line between the charging gun of the charging pile and the vehicle end.

[0026] The fault instruction is used to instruct to disconnect the self-recovery relay. In one example, the fault instruction is automatically generated when an abnormality is detected in the working state of the charging pile, such as when an abnormality is detected in the signal state of the guide control line (CP line), or it can be generated when a reset control is triggered, such as when a user triggers a reset control installed on the adapter or charging gun, or it can be sent from the background. This embodiment does not limit the generation method of the fault instruction.

[0027] The self-restoring relay is used to connect the charging gun and the guide control line of the vehicle end. Specifically, the self-restoring relay is in the normally closed state. At this time, when the charging gun is connected to the vehicle end, the connection of the guide control line between the charging gun and the vehicle end is in the on state, and the charging gun and the vehicle end can exchange signals through the guide control line. When the self-restoring relay is disconnected, the connection of the guide control line between the charging gun and the vehicle end is in the disconnected state, and the charging gun and the vehicle end cannot exchange signals through the guide control line.

[0028] It should be noted that the self-resetting relay is only used to control the possibility of connecting the guide control line between the charging gun and the vehicle end. Whether the charging gun and the vehicle end can exchange control signals through the guide control line depends on factors such as whether the charging gun and the vehicle end are connected. However, when the self-resetting relay is in the disconnected state, the charging pile and the vehicle end cannot exchange signals through the guide control line.

[0029] In one example, the self-restoring relay can be set in the charging adapter, which includes a first connection end for connecting the charging gun and a second connection end for connecting the vehicle end. Accordingly, the self-restoring relay is used to control the conduction and disconnection of the guide control line connector of the first connection end and the guide control line connector of the second connection end. In actual implementation, the self-restoring relay can also be integrated in the charging gun as long as the corresponding function can be realized. This embodiment does not limit the setting method of the self-restoring relay.

[0030] Step 102, monitoring whether the reclosing condition is met.

[0031] The reclosing condition refers to the condition for closing the self-recovering relay. Specifically, in this embodiment, the connection between the guide control line between the charging gun and the vehicle end can be cut off by disconnecting the self-recovering relay, thereby simulating the gun removal operation. In order to achieve self-recovery of the fault, it is also necessary to simulate the gun insertion operation, so it is necessary to realize the automatic closing of the recovery relay. Before closing the self-recovering relay, it is necessary to determine whether the reclosing condition is met.

[0032] In one example, the reclosing condition can be determined by combining at least one of the factors such as the time the self-recovery relay is disconnected, the connection between the charging gun and the vehicle, the state of the charging pile, the state of the vehicle, etc. For example, the reclosing condition includes the time the self-recovery relay is disconnected reaching the waiting time threshold.

[0033] In another example, the reclosing condition includes that the number of disconnections of the self-recovery relay during the current charging process is less than a preset disconnection threshold, that is, when the number of disconnections of the self-recovery relay during the current charging process is greater than or equal to the preset disconnection threshold, it is determined that the reclosing condition is not met, and a fault alarm message is output. This can help avoid damage to the self-recovery relay due to frequent disconnection and closing.

[0034] Step 103, when monitoring that the reclosing condition is met, control the self-recovery relay to close to re-establish the connection of the guide control line between the charging gun and the vehicle end.

[0035] Specifically, the closed loop of the self-recovering relay can guide the control line between the charging gun and the vehicle end to be reopened, thereby simulating the gun insertion operation.

[0036] Optionally, if the reclosing conditions are not met within the preset monitoring time, the monitoring is terminated and a charging abnormality prompt message is output. For example, if the connection between the charger and the vehicle is disconnected, a disconnection prompt message can be output.

[0037] The implementation principle of a charging pile fault self-recovery method in the embodiment of the present application is: in response to a fault instruction, control the self-recovery relay to disconnect to disconnect the connection of the guide control line between the charging gun of the charging pile and the vehicle end, and the self-recovery relay is used to connect the charging gun and the guide control line of the vehicle end; monitor whether the reclosing condition is met; when it is monitored that the reclosing condition is met, control the self-recovery relay to close to re-establish the connection of the guide control line between the charging gun and the vehicle end. By adopting the above technical solution, in response to a fault instruction, the self-recovery relay can be controlled to disconnect to simulate the gun pulling operation, and when it is monitored that the reclosing condition is met, the self-recovery relay can be controlled to close to simulate the gun plugging operation. In this way, the simulation of plugging and unplugging the gun can be realized by controlling the self-recovery relay without actually plugging and unplugging the gun, which can help to realize automatic fault processing, and then can help to improve the user experience.

[0038] In some embodiments, reference Figure 2 The charging pile fault self-recovery method provided in this embodiment also includes the following steps: Step 201: When the charging gun is connected to the vehicle end, the state of the guide control line is monitored.

[0039] Specifically, the pilot control 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 the control pilot function signal (Control Pilot Function). In actual implementation, the working state of the charging pile can be determined according to the level state of the CP line, such as: preparation state, charging state, etc.

[0040] In one example, a self-resetting relay is provided in a charging adapter, and the charging gun is connected to the vehicle end through the charging adapter. Accordingly, the state of the guide control line can be monitored through the charging adapter.

[0041] In another example, the self-resetting relay is integrated in the charging gun. In this case, the charging gun is directly connected to the vehicle end. Accordingly, the status of the guide control line can be monitored through the charging pile.

[0042] Step 202: Generate a fault instruction when it is detected that the continuous time duration of the guide control line being in the first state exceeds a first time duration threshold.

[0043] The first state is a preparatory state for charging. During normal charging, the guide control line will not be in the first state for a long time.

[0044] Optionally, the first state includes a semi-connected (B1) state, a ready-to-charge (B2) state and / or a fully connected (C2) state.

[0045] In actual implementation, the first duration threshold can be set according to actual conditions, 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 are the same or different.

[0046] Step 203: Generate a fault instruction when it is monitored that the duration during which the pilot control line is in the second state but has no current exceeds a second duration threshold.

[0047] 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 a charging (C2) state.

[0048] In actual implementation, the second duration threshold may be set according to actual needs, for example, the second duration threshold may be 2 minutes.

[0049] In the above technical solution, when the charging pile is connected to the vehicle, the status of the guide control line can be monitored, and abnormal judgment can be made based on the abnormal judgment conditions corresponding to different states, so that when an abnormality is detected, a fault instruction can be automatically generated. In this way, automatic fault judgment and recovery can be achieved without the user having to perform corresponding operations, which can help improve the user's charging experience.

[0050] For further reference, Figure 3 In step 202 or step 203, after generating the fault instruction, the following steps are also included: Step 301, obtaining the electrical output parameters of the charging gun.

[0051] The electrical output parameters are used to indicate the electrical output of the charging gun, such as whether there is voltage. Specifically, the electrical output parameters can be acquired through a sensor component, such as acquiring the electrical output parameters of the charging gun through a sensor component provided in a charging adapter, or can be acquired from a charging pile system or an operation and maintenance background.

[0052] Step 302 : determining the fault type based on the electrical output parameter and the state of the pilot control line.

[0053] Optionally, the fault types include the charging pile not being started and the vehicle end not receiving power.

[0054] In one example, the fault type is determined based on the electrical output parameter and the state of the guide control line, including: when the guide control line is in the second state and the electrical output parameter indicates that there is no voltage, determining the fault type is that the charging pile is not started; when the guide control line is in the second state and the electrical output parameter indicates that there is voltage, determining the fault type is that the vehicle end is not powered.

[0055] Specifically, when an abnormality occurs when the control guide line is in the second state, that is, it is in the charging state but there is no current, the reason for this situation may be that the charging pile is not started or the vehicle end is not powered. Based on this, the above technical solution further determines whether there is voltage based on the electrical output parameters, and finally determines the fault type based on whether there is voltage.

[0056] Furthermore, when the guide control line is in the second state and the electrical output parameter indicates that there is voltage, the fault type is determined as the vehicle end is not receiving power, including: when the guide control line is in the second state and the electrical output parameter indicates that there is 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 the fault type is that the vehicle end is not receiving power; when the voltage is less than the voltage threshold, determining the fault type is insufficient voltage of the charging pile.

[0057] In another example, the first state includes a third state and a fourth state. Accordingly, the fault type is determined based on the electrical output parameters and the state of the guide control line, including: when the guide control line is in the third state, determining that the fault type is that the charging pile is not started; when the guide control line is in the fourth state, determining that the vehicle end is not powered.

[0058] The third charging state is a pre-charging state related to the charging pile, such as a semi-connected (B1) state and a ready-to-charge (B2) state. The fourth charging state is a pre-charging state related to the vehicle, such as a fully connected (C1) state.

[0059] Step 303: output fault prompt information based on the fault type.

[0060] Different fault types correspond to different fault prompt information, so the fault type can be identified based on the fault prompt information.

[0061] Optionally, the fault prompt information may be output through a buzzer or indicator light provided on the charging pile, or may be output through information displayed on the background or user terminal. This embodiment does not limit the output method of the fault prompt information.

[0062] In the above embodiment, after the fault instruction is generated, the fault type can be determined based on the point output parameters of the charging gun and the state of the guide control line, and abnormal prompt information corresponding to the fault type can be output. In this way, the fault prompt information can be output while the fault is automatically processed to indicate that a fault has occurred in the charging process, thereby making it easier for users and managers to understand the abnormalities in the charging process.

[0063] In some embodiments, reference Figure 4 , step 101, in response to a fault instruction, controlling the self-recovery relay to disconnect, comprising the following steps: Step 401, in response to a fault instruction, determining whether the interval time from the last time the self-recovery relay was controlled to be closed is less than an interval time threshold.

[0064] In one example, the interval duration threshold is fixedly set, for example, the interval duration threshold is 10 minutes.

[0065] In another example, the interval time threshold is determined based on the number of disconnections of the self-recovering relay during the current charging process. For example, the greater the number of disconnections, the shorter the interval time.

[0066] Step 402: When the interval duration is greater than or equal to the interval duration threshold, control the self-recovery relay to disconnect.

[0067] Step 403: When the interval duration is less than the interval duration threshold, the interval duration is monitored, and when it is detected that the interval duration reaches the interval duration threshold, the self-recovery relay is controlled to be disconnected.

[0068] Optionally, when it is monitored that the interval duration reaches the interval duration threshold, the self-resetting relay is controlled to disconnect, including: when it is monitored that the interval duration reaches the interval duration threshold, checking whether the current state meets the execution conditions; when the current state meets the execution conditions, controlling the self-resetting relay to disconnect; when the current state does not meet the execution conditions, not controlling the self-resetting relay to disconnect.

[0069] Specifically, since the charging status may change during the waiting interval to reach the interval threshold, for example, from a fault state to a normal state, there is no need to simulate the plug-in and unplug operation, that is, there is no need to control the self-recovery relay to open and close. Therefore, if there is no immediate response to the recovery instruction, it will further determine whether it is necessary to control the self-recovery relay to disconnect under the current conditions. This can help avoid unnecessary disconnection of the self-recovery relay.

[0070] In one example, the execution condition includes the presence of a fault in the charging process. At this time, a check is performed to determine whether the current state satisfies the execution condition, including: determining whether there is a fault in the charging process; if there is a fault in the charging process, determining that the execution verification condition is met; if there is no fault in the charging process, determining that the execution verification condition is not met.

[0071] The method of determining whether there is a fault in the charging process can be analogous to the generation conditions of the fault instructions in steps 201 to 203 .

[0072] Furthermore, before determining whether the self-resetting relay has a fault, the step includes: determining whether the fault instruction is automatically generated when the fault is detected; if so, executing the step of determining whether the self-resetting relay has a fault; if not, determining whether the verification condition is met can be executed, or determining whether the verification condition is met based on other methods.

[0073] Accordingly, the fault instruction may be automatically generated when a fault is detected, or may be generated when a reset control is triggered.

[0074] In the above technical solution, when a fault instruction is received, the relationship between the interval time from the last time the self-recovery relay was controlled to close and the interval time threshold will be further determined to determine whether to control the self-recovery relay to disconnect. In this way, there can be a certain time interval between the closing and disconnecting of the self-recovery relay, which can help avoid damage to the self-recovery relay due to frequent disconnection and closing.

[0075] In some embodiments, step 102, monitoring whether the reclosing condition is met, includes: determining whether the waiting time reaches a waiting time threshold; and determining that the reclosing condition is met when the waiting time reaches the waiting time threshold.

[0076] The waiting time is calculated from the time the self-control self-recovery relay is disconnected. Specifically, the waiting time can be fixed, for example, the waiting time is 10 seconds, or it can be dynamically determined, for example, it is determined in combination with the number of disconnections during this charging process. The greater the number of disconnections, the longer the waiting time. The waiting time corresponding to different numbers of disconnections can be predetermined.

[0077] In the above implementation, by setting the waiting time threshold, the time interval between the self-recovery relay being disconnected and then reopened can be controlled. This can reserve time for the charging pile to react to the guidance control signal, thereby ensuring that the charging pile can respond to the disconnection of the guidance control line, thereby ensuring the effect of simulating plugging and unplugging.

[0078] Based on the above implementation, further, when the waiting time reaches the waiting time threshold, determining that the reclosing condition is met includes the following steps: Step 501: When the waiting time reaches the waiting time threshold, determine whether the connection between the charging gun and the vehicle end is disconnected.

[0079] In one example, a self-resetting relay is set in the charging adapter. At this time, the charging gun is connected to the vehicle end through the charging adapter. Accordingly, it can be determined whether the connection between the charging gun and the vehicle end is disconnected through the connection relationship between the charging adapter, the charging gun and the vehicle end. For example: sensing components are respectively set at the interfaces between the charging adapter, the charging gun and the vehicle end to respectively detect whether the charging gun and the vehicle end are connected.

[0080] In another example, the self-resetting relay is integrated in the charging gun. In this case, the charging gun is directly connected to the vehicle end. Accordingly, it is possible to directly monitor whether the connection between the charging gun and the vehicle end is disconnected. For example, an induction component is set at the charging gun muzzle interface to sense whether the charging gun is inserted into the vehicle end.

[0081] Step 502: Acquire the status data of the charging pile when the connection between the charging gun and the vehicle end is not disconnected.

[0082] 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 pass connection between the charging pile management systems.

[0083] Optionally, when the connection between the charging gun and the vehicle end is disconnected, it is determined that the reclosing condition is not met, and a disconnection prompt message is output to prompt that the connection between the charging gun and the vehicle end is disconnected. Further, when the connection between the charging gun and the vehicle end is restored within a preset verification time after the disconnection prompt message is output, the status data of the charging pile can be obtained, and steps 503 to 505 can be executed.

[0084] In one example, a self-recovering relay is provided in the charging adapter, and 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.

[0085] In another example, a self-resetting relay is integrated into the charging gun, where the status data of the charging pile can be directly obtained.

[0086] Step 503: Determine whether the charging pile meets the reconnection condition based on the status data.

[0087] In one example, the reconnection condition includes the charging pile being in a ready-to-power state. Specifically, before being activated, the charging pile is in a standby state, and the user needs to create a charging order by swiping a card or scanning a code. After receiving the charging order information, the charging pile will switch to a ready-to-power state to power the vehicle.

[0088] Correspondingly, determining whether the charging pile meets the reconnection condition based on the status data includes: determining whether the charging pile is in a state ready to supply power; if so, determining that the charging pile meets the reconnection condition; if not, determining that the charging pile does not meet the reconnection condition.

[0089] In another example, the reconnection condition includes a prompt from the charging pile to connect to the vehicle end. Specifically, under normal circumstances, when the charging pile detects that the guidance control signal is interrupted, it will determine that the vehicle end is disconnected and output a prompt message to connect to the vehicle end.

[0090] 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.

[0091] In other examples, the reconnection conditions include the absence of output current and output voltage of the charging gun. Specifically, since the control self-resetting relay closure indicates the simulated gun pulling operation, the charging gun is not disconnected from the vehicle end. Therefore, there may be abnormal current and voltage output. At this time, corresponding processing is required to ensure the safety of the reconnection process.

[0092] Step 504: When it is determined that the charging pile does not meet the reconnection condition, a reconnection instruction is sent to the charging pile.

[0093] The reconnection instruction is used to instruct the charging pile to adjust the status data to meet the reconnection condition. Specifically, the reconnection instruction can be sent directly to the charging pile, or can be sent to the charging pile through the charging pile management system.

[0094] Correspondingly, under normal circumstances, the charging pile will adjust the state in response to the reconnection instruction so that the state data meets the reconnection condition.

[0095] Optionally, after sending the reconnection instruction to the charging pile, it also includes: after a preset adjustment time threshold, reacquiring the status data of the charging pile, returning to execute whether the charging pile meets the reconnection condition based on the status data, that is, returning to execute step 503.

[0096] Step 505: When it is determined that the charging pile meets the reconnection condition, it is determined that the reclosing condition is met.
