[0002] Compared with fuel vehicles, new energy vehicles have a shorter cruising range, so charging operations are frequent. In order to improve the charging speed, the power of the charging pile is relatively high, and the current provided is also relatively large. When the vehicle charging is completed, it is necessary to unplug the vehicle charging cable from the charging pile. During the process of unplugging the charging cable, due to improper software logic control of the on-vehicle charger or the charging pile, there may still be a large current at the charging interface when unplugging the gun, and the power-off is not complete, resulting in arcing, thus there is an ablation phenomenon of the charging gun. And since it is not clear which side has a problem, the ablation problem of the charging gun cannot be solved, thus affecting the user experience.

[0046] It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0047] Refer to Figure 1 , Figure 1 Schematic diagram of the structure of the ablation detection device in the hardware operating environment related to the embodiment solution of the present invention.

[0048] Such as Figure 1As shown in the figure, the ablation detection device may include: a processor 1001, such as a Central Processing Unit (CPU), a communication bus 1002, a user interface 1003, a network interface 1004, and a memory 1005. Among them, the communication bus 1002 is used to realize the connection and communication between these components. The user interface 1003 may include a display screen (Display) and an input unit such as a keyboard (Keyboard). Optionally, the user interface 1003 may further include a standard wired interface and a wireless interface. The network interface 1004 may optionally include a standard wired interface and a wireless interface (such as a Wireless-Fidelity (Wi-Fi) interface). The memory 1005 may be a high-speed Random Access Memory (RAM) or a stable Non-Volatile Memory (NVM), such as a disk memory. Optionally, the memory 1005 may also be a storage device independent of the aforementioned processor 1001.

[0049] Those skilled in the art can understand that Figure 1 the structure shown in the figure does not constitute a limitation on the ablation detection device, and it may include more or fewer components than shown in the figure, or combine some components, or have different component arrangements.

[0050] As Figure 1 shown, the memory 1005, as a storage medium, may include an operating system, a network communication module, a user interface module, and an ablation detection program.

[0051] In Figure 1 the ablation detection device shown, the network interface 1004 is mainly used for data communication with a network server; the user interface 1003 is mainly used for data interaction with a user; the processor 1001 and the memory 1005 in the ablation detection device of the present invention may be arranged in the ablation detection device. The ablation detection device calls the ablation detection program stored in the memory 1005 through the processor 1001 and executes the ablation detection method provided by the embodiments of the present invention.

[0052] The embodiments of the present invention provide an ablation detection method. Referring to Figure 2 , Figure 2 it is a schematic flowchart of the first embodiment of an ablation detection method of the present invention.

[0053] In this embodiment, the ablation detection method includes the following steps:

[0054] Step S10: When receiving an ablation detection instruction, disconnect the charging connection line between the charging pile and the vehicle according to the ablation detection instruction.

[0055] It should be noted that the execution entity of the method in this embodiment can be a device with data transmission, data collection, and data processing functions, such as a computer or a control computer and other test devices, or other devices with the same or similar functions. This embodiment does not make specific restrictions in this regard. In this embodiment and the following embodiments, the control computer will be used as an example of the test device for illustration.

[0056] It is worth noting that the ablation detection instruction can be a control instruction issued by the user to control the disconnection of the charging connection line between the charging pile and the vehicle, so as to collect power-off information. Among them, a charging adapter cable can be added between the charging pile and the vehicle to obtain more accurate power-off information on the vehicle side and the power-off information on the charging pile side when collecting the power-off information.

[0057] In specific implementation, the charging adapter cable in this embodiment can be a charging adapter cable that meets the national standard "GBT37133-2018 Technical Requirements for High-Voltage and High-Current Wiring Harnesses and Connectors for Electric Vehicles". This embodiment does not make specific restrictions in this regard. Among them, the first end of the charging adapter cable is connected to the charging interface of the charging pile, and the second end of the charging adapter cable is connected to the charging interface of the vehicle.

[0058] Step S20: Obtain the target power-off information and determine the power-off reset time according to the target power-off information.

[0059] It should be understood that the target power-off information refers to the power-off information on the vehicle side and the power-off information on the charging pile side. Among them, the power-off information includes: power-off current, power-off voltage, power-off clock signal, etc. This embodiment does not make specific restrictions in this regard.

[0060] In specific implementation, referring to Figure 3 , when collecting the target power-off information, the N-phase current, N-to-ground voltage, CP voltage, etc. on the charging pile side and the vehicle side can be respectively detected and obtained through the oscilloscope probe at the two side ports of the charging adapter cable.

[0061] It is easy to understand that the power-off reset time refers to the current reset time on the charging pile side and the current reset time on the vehicle side when the vehicle and the charging pile are charging and the charging adapter cable is suddenly disconnected.

[0062] Step S30: Compare the power-off reset time with a preset time threshold and determine the source of the ablation fault according to the comparison result.

[0063] It can be understood that the preset time threshold is used to compare with the power-off reset time on the charging pile side and the vehicle side to determine whether there is ablation. Because the ablation of the charging gun is caused by untimely power-off, resulting in a large current impact on the charging gun, thus, by comparing whether the power-off reset time is within the preset time threshold, it is possible to determine whether there is ablation and further determine the source of the ablation fault.

[0064] Further, in order to accurately determine the source of the ablation fault, step S30 includes:

[0065] When the power-off reset time on the vehicle side is greater than the preset time threshold, the source of the ablation fault is ablation on the vehicle side;

[0066] When the power-off reset time on the charging pile side is greater than the preset time threshold, the source of the ablation fault is ablation on the charging pile side.

[0067] It should be noted that in this embodiment, the preset time threshold can be 100 ms, etc., and this embodiment does not make specific restrictions on this.

[0068] In specific implementation, if the power-off reset time on the charging pile side exceeds 100 ms, it indicates that there is ablation on the charging interface of the charging pile; similarly, if the power-off reset time on the vehicle side exceeds 100 ms, it indicates that there is ablation on the charging interface of the vehicle.

[0069] This embodiment discloses an ablation detection method. The ablation detection method includes: when receiving an ablation detection instruction, disconnecting the charging connection line between the charging pile and the vehicle according to the ablation detection instruction; obtaining target power-off information, and determining the power-off reset time according to the target power-off information; comparing the power-off reset time with a preset time threshold, and determining the source of the ablation fault according to the comparison result. In this embodiment, by separately obtaining the target power-off information on the charging pile side and the vehicle side at the power-off moment, then determining the corresponding power-off reset time according to the target power-off information, comparing the power-off reset time with the preset time threshold, and finally accurately positioning the source of the ablation fault according to the comparison result, it avoids the technical problem in the prior art that when the charging pile is separated from the charging gun, the source of the ablation cannot be detected.

[0070] Reference Figure 4 , Figure 4 is a schematic flowchart of the second embodiment of a method for detecting ablation according to the present invention.

[0071] Based on the above first embodiment, in this embodiment, step S20 includes:

[0072] Step S201: Obtain the power-off information on the charging pile side and the power-off information on the vehicle side at the power-off moment.

[0073] It should be noted that, in order to better obtain the power-off information on the charging pile side and the power-off information on the vehicle side, in this embodiment, the vehicle and the charging pile can be connected through a charging adapter cable first, then the charging pile starts to supply power and the vehicle starts to charge, and then the charging connection on one side is disconnected respectively, and the corresponding power-off information is measured through an oscilloscope probe.

[0074] Further, step S201 includes:

[0075] Determine the collection point set on the charging pile side and the collection point set on the vehicle side;

[0076] Based on the collection point set on the charging pile side, respectively collect the power-off current on the charging pile side, the power-off voltage on the charging pile side, and the power-off clock signal on the charging pile side through a preset data acquisition device;

[0077] Based on the collection point set on the vehicle side, respectively collect the power-off current on the vehicle side, the power-off voltage on the vehicle side, and the power-off clock signal on the vehicle side through a preset data acquisition device.

[0078] It can be understood that, referring to Figure 3 , there are three collection point sets on the charging pile side in this embodiment, which are respectively used to collect the power-off current on the charging pile side, the power-off voltage on the charging pile side, and the power-off clock signal on the charging pile side, that is, corresponding to the N-phase current I1, the N-to-ground voltage U1, and the CP voltage u1. There are also three collection point sets on the vehicle side, corresponding to collecting the power-off current on the vehicle side, the power-off voltage on the vehicle side, and the power-off clock signal on the vehicle side, that is, the N-phase current I2, the N-to-ground voltage U2, and the CP voltage u2.

[0079] In addition, in this embodiment, the preset data acquisition device can be an oscilloscope, or other devices with data acquisition functions, such as: a multimeter or a current-voltage test device, etc. This embodiment does not make specific limitations on this.

[0080] In specific implementation, referring to Figure 3 , during the charging process, unplug the gun at unplugging point 1, that is, pull out the adapter cable port 1 from the vehicle charging port seat. The oscilloscope records the complete waveforms of the N-phase current I1, the N-to-ground voltage U1, and the CP voltage u1 collected when pulling out the slow charging gun. Then reconnect the charging connection cable and keep the charging connection. By unplugging the gun at unplugging point 2 during the charging process, that is, pulling out the adapter cable port 2 from the charging pile power supply port seat, the oscilloscope records the complete waveforms of the N-phase current I2, the N-to-ground voltage U2, and the CP voltage u2 collected when pulling out the slow charging gun.

[0081] Step S202: Determine the power-off zeroing time on the charging pile side according to the power-off information on the charging pile side, and determine the power-off zeroing time on the vehicle side according to the power-off information on the vehicle side.

[0082] It should be noted that the corresponding power-off return-to-zero time can be obtained from the waveform image collected by the oscilloscope when drawing the gun. Refer to Figure 5 and Figure 6 , Figure 5 is the power-off information on the vehicle side, Figure 6 is the breakpoint information on the charging pile side.

[0083] In a specific implementation, if the power-off return-to-zero times on both sides are less than 100 ms, it indicates that there is no ablation phenomenon. For example: Figure 5 and Figure 6 , the power-off return-to-zero time on the vehicle side is 88.2 ms, and the power-off return-to-zero time on the charging pile side is 73 ms, then there is no ablation phenomenon on both the charging pile side and the vehicle side.

[0084] This embodiment discloses obtaining the power-off information on the charging pile side and the power-off information on the vehicle side at the power-off moment; determining the power-off return-to-zero time on the charging pile side according to the power-off information on the charging pile side, and determining the power-off return-to-zero time on the vehicle side according to the power-off information on the vehicle side. In this embodiment, by respectively obtaining the power-off information on the charging pile side and the power-off information on the vehicle side, the corresponding power-off return-to-zero time on the charging pile side and the power-off return-to-zero time on the vehicle side are obtained, so as to facilitate subsequent comparison of the return-to-zero times to determine the accurate source of ablation failure.

[0085] Refer to Figure 7 , Figure 7 which is a schematic flowchart of the third embodiment of a method for detecting ablation of the present invention.

[0086] Based on the above second embodiment, in this embodiment, after the step S30, it further includes:

[0087] Step S40: Detect whether the charging pile or the vehicle meets a preset power-off condition, and determine the power-off time sequence corresponding to the source of the ablation failure according to the detection result.

[0088] It should be noted that the preset power-off condition may be: the charging pile clock voltage value is not equal to the preset voltage threshold, detecting that the CC interface end or the CP interface end on the vehicle side is disconnected, and receiving other power-off signals, etc. This embodiment does not make specific limitations on this.

[0089] Further, the step S40 includes:

[0090] Obtain the charging pile clock voltage value of the CP interface end on the charging pile side;

[0091] When the charging pile clock voltage value is not equal to the preset voltage threshold, obtain the power-off time sequence on the charging pile side;

[0092] When it is detected that the CC interface end or the CP interface end on the vehicle side is disconnected, obtain the target power-off time sequence on the vehicle side.

[0093] It should be noted that the preset voltage threshold can be the standard power supply clock voltage, which can be 6V in this embodiment, or other voltage values. This embodiment does not make specific limitations on this.

[0094] In addition, the power-off timing on the charging pile side means that when the charging pile side meets the power-off condition, the charging will be controlled to power off based on this power-off timing.

[0095] In specific implementation, when the CP voltage on the charging pile side is 12V, 9V, and other voltage values other than 6V, the power-off timing of the charging pile is obtained.

[0096] It can be understood that referring to Figure 3 the test connection line in [reference], during the charging process, when the vehicle control device detects that the CC interface end is disconnected, it controls the on-vehicle charger to stop charging within 100 ms, and then disconnects the charging switch S2; during the charging process, when the vehicle control device detects the interruption of the PWM signal at the CP interface end, it controls the on-vehicle charger to stop charging within 3 s, and then disconnects the charging switch S2.

[0097] Furthermore, if the user needs to perform vehicle power-off through manual operation, after the step of obtaining the target vehicle-side power-off timing when detecting the disconnection of the vehicle-side CC interface end or CP interface end, it further includes:

[0098] When receiving the vehicle-side power-off switch signal, determine the target vehicle-side power-off timing according to the power-off switch signal.

[0099] It should be noted that the vehicle-side power-off switch signal refers to the user's manual interference in the vehicle-side power-off process. For example: controlling through the charging switch on the charging gun or through software, etc. This embodiment does not make specific limitations on this.

[0100] Step S50: Control the charging connection between the charging pile and the vehicle to be disconnected according to the power-off timing.

[0101] In specific implementation, according to the power-off timing corresponding to different power-off scenarios, control the disconnection of the charging connection between the charging pile and the vehicle, avoid the occurrence of ablation, greatly reduce the probability of safety accidents, and reduce costs.

[0102] This embodiment discloses detecting whether the charging pile or the vehicle meets the preset power-off condition, and determining the power-off timing corresponding to the ablation fault source according to the detection result; controlling the charging connection between the charging pile and the vehicle to be disconnected according to the power-off timing. This embodiment determines the corresponding power-off timing by judging the power-off conditions of the vehicle and the charging pile, and then performs power-off according to this power-off timing to avoid ablation.

[0103] In addition, an embodiment of the present invention further provides a storage medium, on which an ablation detection program is stored. When the ablation detection program is executed by a processor, the steps of the ablation detection method described above are implemented.

[0104] Since this storage medium adopts all the technical solutions of the above-mentioned all embodiments, it has at least all the beneficial effects brought by the technical solutions of the above-mentioned embodiments, which will not be elaborated one by one here.
