[0002] With the rapid development of the global electric vehicle industry, electric vehicles in different regions need to meet the charging standards of each region.

A plurality of path wires can be provided between the first connection port 11 and the second connection port 12.

[0044] In an embodiment of the present application, the charging test system includes a charging protocol converter 10, a target control module 20, an analysis module 30 and a communication control module 40; the charging protocol converter 10 includes a first connection port 11 and a second connection port 12, the first connection port 11 is connected to the electric vehicle; the first connection port 11 is connected to the second connection port 12 through the target control module 20; the second connection port 12 is connected to the analysis module 30, and the second connection port 12 is used to obtain target data through the analysis module 30; the communication control module 40 is respectively connected to the target control module 20 and the analysis module 30, the communication control module 40 is used to control the opening and closing of the target control module 20, and the communication control module 40 is also used to generate charging test results of the electric vehicle based on the target data. Therefore, the charging test system can be connected to the electric vehicle through the first connection port 11, so that the charging protocol converter 10 can perform EVCC testing in the charging environment of the actual vehicle, so that relevant personnel such as testing and R&D can obtain accurate EVCC test data.

[0045] In one embodiment, the analysis module 30 includes a waveform analyzer 31, the target control module 20 includes a first control switch 21 and a second control switch 22, the first end of the first connection port 11 is connected to the first end of the second connection port 12 through the first control switch 21, the second end of the first connection port 11 is connected to the second end of the second connection port 12 through the second control switch 22, the first channel of the waveform analyzer 31 is connected to the first end of the second connection port 12, and the second channel of the waveform analyzer 31 is connected to the second end of the second connection port 12. The communication control module 40 is connected to the first control switch 21 and the second control switch 22 respectively, and the communication control module 40 is used to control the opening and closing of the first control switch 21 and / or the second control switch 22 to obtain the analysis data of the first channel and / or the second channel of the waveform analyzer 31.

[0046] Specifically, the waveform analyzer 31 is used to capture and analyze the signal waveform of the signal between the first connection port 11 and the second connection port 12 during the charging process to verify whether the response of the target control module 20 is in line with expectations, and whether the communication and control during the charging process are correct, so as to ensure the reliability of the charging protocol converter 10. When the first control switch 21 is closed, the circuit between the first end of the first connection port 11, the first control switch 21 and the first end of the second connection port 12 is turned on, and the relevant signal of the first connection port 11 can be input to the waveform analyzer 31 through the path wire between the first end of the first connection port 11, the first control switch 21 and the first end of the second connection port 12. When the second control switch 22 is closed, the circuit between the second end of the first connection port 11, the second control switch 22 and the second end of the second connection port 12 is turned on, and the relevant signal of the waveform analyzer 31 can be output to the controller 41 inside the tram through the passage wire between the second end of the second connection port 12, the second control switch 22 and the second end of the first connection port 11; or, the relevant signal of the controller 41 inside the tram can be input to the waveform analyzer 31 through the passage wire between the second end of the first connection port 11, the second control switch 22 and the second end of the second connection port 12.

[0047] In this process, the communication control module 40 can obtain the analysis data of the first channel and / or the second channel of the waveform analyzer 31 by controlling the opening and closing of the first control switch 21 and / or the second control switch 22, verify whether the communication and control during the charging process are correct, and obtain the charging test results of the electric vehicle.

[0048] Optionally, when the electric vehicle is connected to the charging pile 71, the first end of the first connection port 11 is connected to the charging pile 71, the first connection port 11 is used to obtain the first communication signal of the charging pile 71 during the charging process, and the second connection port 12 is used to guide the first communication signal to be input into the waveform analyzer 31; the second end of the first connection port 11 is connected to the on-board charger 72 of the electric vehicle, the communication control module 40 is used to control the closing of the second control switch 22, and the waveform analyzer 31 is used to output the first communication signal to the on-board charger 72 through the first connection port 11 and the second connection port 12.

[0049] Specifically, the first control switch 21 includes but is not limited to a CP relay. A CP path conductor is formed between the first end of the first connection port 11, the first control switch 21 and the first end of the second connection port 12. The first end of the first connection port 11 is used to receive the first communication signal CP during the charging process, and when the first control switch 21 is closed, it is transmitted to the first end of the second transmission port through the CP path conductor to guide the first communication signal CP to be input into the waveform analyzer 31. The second control switch 22 includes but is not limited to a CP-OUT relay. A CP-OUT path conductor is formed between the second end of the first connection port 11, the second control switch 22 and the second end of the second connection port 12. The second end of the second connection port 12 is used to receive the first communication signal CP output by the waveform analyzer 31. When the second control switch 22 is closed, the first communication signal CP is transmitted to the second end of the first transmission port through the CP-OUT path conductor to achieve the output of the first communication signal CP; alternatively, the second control switch 22 is used to control the conduction or disconnection of the CP-OUT path conductor in response to changes in the CP signal. The second control switch 22 is also used to return the state signal of the conduction or disconnection of the CP-OUT path conductor to the waveform analyzer 31, so that the waveform analyzer 31 generates target data based on the first communication signal CP, the state change of the CP-OUT relay, etc.

[0050] In the above manner, when the first control switch 21 and the second control switch 22 are closed, the first communication signal of the charging pile 71 during the charging process can enter the on-board charger 72 inside the electric vehicle through a communication loop formed between the first end of the first connection port 11, the first control switch 21, the first end of the second connection port 12, the waveform analyzer 31, the second end of the second connection port 12, the second control switch 22, and the first end of the first connection port 11, so that the charging test system of this embodiment can test the communication status of the above-mentioned communication loop through the target data of the waveform analyzer 31, and verify the accuracy of the protocol conversion of the charging protocol converter 10 and the charging process.

[0052] Specifically, in this embodiment, a third control switch 23 is further provided between the first end of the first connection port 11 and the second end of the first connection port 11. When the first control switch 21 and the second control switch 22 are disconnected and the third control switch 23 is closed, the first communication signal CP obtained by the first connection port 11 from the charging pile 71 can be output to the on-board charger 72 inside the electric vehicle from the communication loop formed between the first end of the first connection port 11, the third control switch 23 and the second end of the first connection port 11.

[0053] Therefore, the charging test system of this embodiment can control the opening and closing of the first control switch 21, the second control switch 22 and the third control switch 23 in the test scenario of charging abnormality of the charging pile 71, so that the first communication signal CP can skip the loop between the first control switch 21 and the second control switch 22 without destroying the wiring harness loop of the current charging test system, and directly connect to the on-board charger 72 from the third control switch 23, so as to judge the specific location of the charging abnormality through the change of the target data of the analysis module 30 in this process, realize the troubleshooting when the charging is abnormal and narrow the abnormal range. In addition, the communication control module 40 of this embodiment can be connected to an external intelligent communication device, such as a laptop computer, a diagnostic instrument, etc., so that the staff can perform troubleshooting through the opening and closing control of the communication control module 40 in the actual charging scenario, which is suitable for non-professional personnel, reduces the test threshold, and enables the staff to quickly determine the fault direction through the intelligent communication device, thereby improving the troubleshooting efficiency.

[0054] Optionally, the target control module 20 also includes a fourth control switch 24, the analysis module 30 includes a voltage meter 32, the third end of the first connection port 11 is connected to the third end of the second connection port 12 through the fourth control switch 24, the fourth control switch 24 is connected to the communication control module 40, the first end of the voltage meter 32 is connected to the third end of the second connection port 12, the second end of the voltage meter 32 is connected to the fifth end of the second connection port 12, and the fifth end of the second connection port 12 is grounded; wherein, the third end of the first connection port 11 is connected to the battery management system 73 of the electric vehicle, and the fifth end of the second connection port 12 is respectively connected to the first channel of the waveform analyzer 31 and the second channel of the waveform analyzer 31.

[0055] Specifically, the fourth control switch 24 of the target control module 20 includes but is not limited to a wake_up relay, which is used to guide the wake-up signal to output the wake-up signal to the battery management system 73 and wake up the battery management system 73. A wake_up path conductor is formed between the third end of the first connection port 11, the fourth control switch 24, and the third end of the second connection port 12. When the third end of the second connection port 12 needs to send a wake-up signal to the battery management system 73 during the charging process, the wake-up signal is transmitted to the third end of the first transmission port through the wake_up path conductor when the fourth control switch 24 is closed, so as to input the wake-up signal to the battery management system 73.

[0056] Furthermore, the positive electrode of the first channel of the waveform analyzer 31 is connected to the first end of the second connection port 12, the negative electrode of the first channel of the waveform analyzer 31 is connected to the fifth end of the second connection port 12, the positive electrode of the second channel of the waveform analyzer 31 is connected to the second end of the second connection port 12, the negative electrode of the second channel of the waveform analyzer 31 is connected to the fifth end of the second connection port 12, and the fifth end of the second connection port 12 is grounded. When the voltage measurer 32 is connected between the third end and the fifth end of the second connection port 12, the voltage measurer 32 can be used to measure the voltage between the third end of the second connection port 12 and the ground end to obtain voltage measurement data of the voltage measurer 32, and the voltage measurement data can be used to indicate whether the output of the wake-up path wire is normal.

[0057] Therefore, the charging test system of this embodiment can control the opening and closing of the fourth control switch 24 through the communication control module 40 to test the wake_up path wire between the first connection port 11 and the second connection port 12, so as to verify the communication and control process between the charging protocol converter 10 and the battery management system 73 inside the electric vehicle, and ensure the communication accuracy between the charging protocol converter 10 and the battery management system 73.

[0058] In one embodiment, the target control module 20 also includes a fifth control switch 25, the fourth end of the first connection port 11 is connected to the fourth end of the second connection port 12 through the fifth control switch 25, and the fifth control switch 25 is connected to the communication control module 40. The communication control module 40 is used to control the fifth control switch 25 to be closed to obtain a key ignition signal (Accessories, ACC).

[0059] Specifically, the fifth control switch 25 of the target control module 20 includes but is not limited to a KL15 relay, which is used to assist in the wake-up of the EVCC test, and the KL15 relay is used to generate a key ignition signal to wake up the communication of the second connection port 12 through the key ignition signal. A KL15 access wire is formed between the fourth end of the first connection port 11, the fifth control switch 25, and the fourth end of the second connection port 12. When a test is required, the fourth end of the first connection port 11 is transmitted to the fourth end of the second connection port 12 through the KL15 access wire when the fifth control switch 25 is closed, so that the second connection port 12 can communicate with other components later.

[0060] Therefore, the charging test system of this embodiment can control the opening and closing of the fifth control switch 25 through the communication control module 40 to test the KL15 path wire between the first connection port 11 and the second connection port 12, and test and verify the EVCC wake-up process to ensure the accuracy of the charging protocol conversion.

[0061] In one embodiment, the analysis module 30 may include a first communication unit 33 and / or a second communication unit 34. Specifically, the sixth end of the second connection port 12 is connected to the first end of the first communication unit 33, and the second end of the first communication unit 33 is connected to the communication control module 40, and the communication control module 40 is used to obtain the whole vehicle target data of the electric vehicle through the first communication unit 33. The seventh end of the second connection port 12 is connected to the first end of the second communication unit 34, and the second end of the second communication unit 34 is connected to the communication control module 40, and the communication control module 40 is used to obtain the charging target data of the electric vehicle through the second communication unit 34.

[0062] It can be understood that the second connection port 12 realizes different types of communication transmission through the above-mentioned first communication unit 33 and second communication unit 34 respectively. The communication control module 40 is used to obtain the whole vehicle target data of the electric vehicle through the first communication unit 33. The first communication unit 33 is used to transmit the communication between the charging protocol converter 10 and the battery management system 73 (BMS), the motor controller 41 (VCU), the vehicle display system and other real-time devices. The whole vehicle target data includes but is not limited to the communication target data between the charging protocol converter 10 and the battery management system 73, the motor controller 41, the vehicle display system and other real-time devices. The communication control module 40 is used to obtain the charging target data of the electric vehicle through the second communication unit 34. The second communication unit 34 is also used to transmit the communication between the vehicle charger 72, the charging pile 71 or the battery management system 73 during the charging process. The charging target data includes but is not limited to the message data of the charging status, charging protection, etc.

[0063] Therefore, the charging test system of this embodiment can obtain relevant target data of the first communication unit 33 and / or the second communication unit 34 through the communication control module 40, so as to verify whether the response of the target control module 20 meets expectations and whether the communication and control during the charging process are correct based on the changes in the target data during the opening and closing process of the target control module 20, thereby ensuring the reliability of the charging protocol converter 10.

[0064] In one embodiment, the analysis module 30 may be but is not limited to at least one of the waveform analyzer 31, the voltage measurer 32, the first communication unit 33 and the second communication unit 34. The analysis module 30 is used to monitor and analyze the data of the charging protocol converter 10 during the test process to obtain the target data, so that the communication control module 40 can automatically test the charging protocol converter 10 through the target data transmitted by the analysis module 30. Without manual supervision of the data, the automatic test routine and the recording of the process data can be realized, thereby reducing the manual participation in the charging test process, improving the usability of the charging test system for non-professionals, and further improving the efficiency of the charging test.

[0065] In another embodiment, the analysis module 30 may be an input device for inputting data of the charging protocol converter 10 during the test process into the communication control module 40. At this time, at least one of the waveform analyzer 31, the voltage measurer 32, the first communication unit 33 and the second communication unit 34 is only connected to the second connection port 12, and at least one of the waveform analyzer 31, the voltage measurer 32, the first communication unit 33 and the second communication unit 34 obtains the target data of the charging protocol converter 10 during the test process from the second connection port 12, and the staff is used to input the target data of at least one of the waveform analyzer 31, the voltage measurer 32, the first communication unit 33 and the second communication unit 34 into the analysis module 30 manually or through related algorithms, so that the communication control module 40 can perform EVCC test on the charging protocol converter 10 through the target data transmitted by the analysis module 30.

[0066] In one embodiment, the charging test system includes a power supply module 60, which is respectively connected to the fifth end of the first connection port 11, the sixth end of the second connection port 12, and the communication control module 40, and the power supply module 60 is used to supply power to the first connection port 11, the second connection port 12, and the communication control module 40. For example, the power supply module 60 can be a KL30 module to provide regular power supply for the charging test system.

[0067] In one embodiment, if Figure 3As shown, the communication control module 40 may include a controller 41 and a host computer 42. The controller 41 is used to control the opening and closing of the control switch of the target control module 20, and the controller 41 may also be provided with an auxiliary source output. The host computer 42 is connected to the controller 41. The host computer 42 is used to collect vehicle or charging-related data, messages, etc. during the charging process through the first communication unit 33 and the second communication unit 34. The host computer 42 is also used to interact with the controller 41 and related expansion devices such as the waveform analyzer 31 and the voltage meter 32.

[0068] The present application also provides a charging test method, which is applied to the charging test system of any of the above embodiments. Figure 4 , Figure 4 1 is a flow chart of the first embodiment of the charging test method provided by the present application. Figure 4 As shown, in this embodiment, the charging test method includes the following steps:

[0069] Step S11: in response to receiving the charging test instruction, controlling the opening and closing of the target control module 20 of the charging test system.

[0070] Specifically, the charging test instruction may be a test instruction generated by a staff member when operating an intelligent communication device connected to the charging test system, or may be a test instruction automatically generated by the charging test system based on a preset program, which is not specifically limited here. Upon receiving the charging test instruction, the opening and closing of the corresponding relay switch in the target control module 20 is controlled based on the command in the charging test instruction to perform the EVCC test.

[0071] Step S12: receiving target data from the analysis module 30 of the charging test system.

[0072] Specifically, the analysis module 30 can be understood as a device in the charging test system for communicating, transmitting, converting, analyzing, etc. the data of the charging protocol converter 10 during the test process, and the target data of the analysis module 30 can be the relevant data generated during the test process of the charging protocol converter 10. Exemplarily, the target data can be, but is not limited to, the relevant data or signal obtained by at least one of the waveform analyzer 31, the voltage measurer 32, the first communication unit 33, and the second communication unit 34.

[0073] Step S13: Generate the charging test result of the electric vehicle based on the target data.

[0074] After acquiring the target data, a charging test result of the electric vehicle is generated based on the target data. The charging test result may include but is not limited to the test process data of the charging protocol converter 10, the number and result of the test cycles of the charging protocol converter 10, the fault conditions of the charging protocol converter 10 during the test, and the troubleshooting results.

[0075] In an embodiment of the present application, the charging test method controls the opening and closing of the target control module 20 of the charging test system in response to receiving a charging test instruction, receives the target data of the analysis module 30, and generates a charging test result of the electric vehicle based on the target data. The charging test method performs EVCC testing in a real vehicle charging environment by controlling the opening and closing of the target control module 20, so that relevant personnel such as testing and R&D can obtain accurate EVCC test data, thereby improving the efficiency of EVCC testing while realizing automated testing of EVCC and improving the reliability of the charging test system.

[0076] In one embodiment, see Figure 5 , Figure 5 2 is a flow chart of the second embodiment of the charging test method provided by the present application. Figure 5 As shown, in this embodiment, the charging test method includes the following steps:

[0077] Step S21: in response to the received first test instruction indicating that the first charging mode of the electric vehicle is abnormal, the first control switch 21, the second control switch 22 and the fifth control switch 25 of the control target control module 20 are controlled to be closed.

[0078] Specifically, the charging test method of this embodiment controls the charging protocol converter 10 to enter the first charging mode, and when the electric vehicle fails to charge in the first charging mode, it can be determined that the first charging mode of the electric vehicle is abnormal. Among them, the first charging mode can be understood as the slow charging mode of the electric vehicle. In the slow charging mode, the electric vehicle is connected to the slow charging gun in the charging pile 71. The first test instruction can be a test instruction generated by the user when the user finds that the first charging mode of the electric vehicle is abnormal, or it can be a test instruction automatically generated by the charging protocol converter 10 when the user finds that the first charging mode of the electric vehicle is abnormal, which is not specifically limited here.

[0079] When the received first test instruction indicates that the first charging mode of the electric vehicle is abnormal, the first control switch 21, the second control switch 22 and the fifth control switch 25 of the target control module 20 are controlled to be closed. In a possible implementation, the first control switch 21, the second control switch 22 and the fifth control switch 25 of the target control module 20 are all normally closed switches, so when the first charging mode is abnormal, the first control switch 21, the second control switch 22 and the fifth control switch 25 may not be substantially controlled, so that the first control switch 21, the second control switch 22 and the fifth control switch 25 remain in a closed state.

[0080] Step S22 : receiving the first analysis data from the waveform analyzer 31 .

[0081] When the first control switch 21, the second control switch 22 and the fifth control switch 25 are closed, the first analysis data of the waveform analyzer 31 is received. The first analysis data is the analysis data obtained when the waveform analyzer 31 analyzes the first communication signal CP. The first analysis data includes first state data of the first channel and second state data of the second channel. The first state data and the second state data can be represented by the duty cycle parameters and amplitude parameters under the channel.

[0082] Step S23: When the first analysis data meets the first preset condition, a first test result is generated, and the first test result is used to indicate that the charging pile 71 of the charging test system is faulty.

[0083] Specifically, when the first analysis data meets the first preset condition, that is, the duty cycle parameter and auxiliary parameter of the first state data, and the duty cycle parameter and amplitude parameter of the second state data meet the first preset condition, it can be determined that the slow charging anomaly is caused by the failure of the charging pile 71, and the first test result is generated. Exemplarily, when the duty cycle parameter of the first state data is 100%, the amplitude parameter is 12V, and the duty cycle parameter of the second state data is 0%, and the amplitude parameter is 12V, it is determined that the first analysis data meets the first preset condition.

[0084] Step S24: When the first analysis data meets the second preset condition, a second test result is generated, and the second test result is used to indicate that the on-board charger 72 of the charging test system is faulty.

[0085] When the first analysis data meets the second preset condition, that is, the duty cycle parameter and auxiliary parameter of the first state data, the duty cycle parameter and amplitude parameter of the second state data meet the second preset condition, it can be determined that the slow charging anomaly is caused by a fault in the on-board charger 72, and a second test result is generated. Exemplarily, when the duty cycle parameter of the first state data is between 80%-90% and the amplitude parameter is 9V, and the duty cycle parameter of the second state data is between 80%-90% and the amplitude parameter is 9V, it is determined that the first analysis data meets the second preset condition.

[0086] Step S25: When the first analysis data meets the third preset condition, the fifth control switch 25, the first control switch 21 and the second control switch 22 are respectively controlled to be opened at preset time intervals, and the third control switch 23 is closed to obtain the vehicle status data of the electric vehicle.

[0087] When the first analysis data meets the third preset condition, that is, the duty cycle parameters and auxiliary parameters of the first state data, and the duty cycle parameters and amplitude parameters of the second state data meet the third preset condition, it can be determined that the slow charging anomaly is caused by the CP-OUT access wire, but the specific fault position on the CP-OUT access wire cannot be located. Therefore. When it is determined that the first analysis data meets the third preset condition, this embodiment controls the fifth control switch 25, the first control switch 21, and the second control switch 22 to be disconnected at preset time intervals, and obtains the vehicle status data of the electric vehicle, so as to locate the specific fault position on the CP-OUT access wire through the vehicle status data.

[0088] Among them, the vehicle status data is the status data of the electric vehicle during the test process obtained by the first communication unit 33, and the vehicle status data can be used to indicate whether the electric vehicle is charging normally. In order to facilitate the control of the fifth control switch 25, the first control switch 21 and the second control switch 22, the above-mentioned preset time interval can be set to a uniform value, such as 2s, 1s, etc. The preset time interval can also be adjusted according to each controlled device, and no specific limitation is made here. For example, when the duty cycle parameter of the first state data is between 80%-90% and the amplitude parameter is 9V, and the duty cycle parameter of the second state data is 0 and the amplitude parameter is 12V, it can be determined that the first analysis data meets the third preset condition.

[0089] Step S26: In response to the vehicle status data indicating that the electric vehicle is charging normally, a third test result is generated.

[0090] Specifically, after disconnecting the fifth control switch 25, the first control switch 21, and the second control switch 22, the CP path wire, the CP-OUT path wire, and the KL15 path wire in the charging test system are cut off, and the first communication signal CP of the charging pile 71 cannot be transmitted through the above-mentioned CP path wire, the CP-OUT path wire, and the KL15 path wire. Since the third control switch 23 is respectively connected to the first end of the first connection port 11 and the second end of the first connection port 11, when the third control switch 23 is closed, the first communication signal CP of the charging pile 71 can be directly connected to the on-board charger 72 through the path wire where the third control switch 23 is located. When the vehicle status data indicates that the electric vehicle is charging normally, that is, the first communication signal CP can be charged normally after bypassing the CP-OUT path wire, at this time, it can be determined that the device output on the CP-OUT path wire is abnormal to generate a third test result. The third test result is used to indicate a component failure on the CP-OUT path wire.

[0091] Step S27: In response to the vehicle status data indicating abnormal charging of the electric vehicle, a fourth test result is generated.

[0092] It can be understood that when the vehicle status data indicates that the electric vehicle is abnormally charged, that is, the first communication signal CP still cannot be charged after bypassing the CP-OUT path wire, at this time, it can be determined that the CP-OUT harness on the second end of the first connection port 11 is open to generate a fourth test result. The fourth test result can be used to indicate that the CP-OUT harness at the second end of the first connection port 11 is open, for example, it can be a fault condition such as poor harness contact.

[0093] Through the above-mentioned manner, the charging test method of this embodiment can locate the fault position of the charging protocol converter 10 when the electric vehicle has a slow charging abnormality; and when the first analysis data meets the third preset condition, it can also control the first communication signal CP to skip the loop between the first control switch 21 and the second control switch 22 without destroying the wiring harness loop of the current charging test system, and directly connect from the third control switch 23 to the on-board charger 72, so as to locate the specific fault position on the CP-OUT path wire through the vehicle status data in this process, thereby realizing fault troubleshooting during charging abnormalities and narrowing the scope of the abnormality.

[0094] In one embodiment, the analysis module 30 includes a first communication unit 33, and the target data includes first target data of the first communication unit 33. Figure 6 , Figure 6 FIG. 1 is a flow chart of the third embodiment of the charging test method provided by the present application. Figure 6 As shown, in this embodiment, the charging test method includes the following steps:

[0095] Step S31 : in response to receiving the second test instruction, the fifth control switch 25 of the control target control module 20 is turned off.

[0096] Specifically, when the tram is in the running mode, the first control switch 21, the second control switch 22, the fourth control switch 24 and the fifth control switch 25 of the target control module 20 are normally closed switches, that is, when the first control switch 21, the second control switch 22, the fourth control switch 24 and the fifth control switch 25 are not controlled, the above-mentioned control switches are closed; the third control switch 23 is a normally open switch, that is, when the third control switch 23 is not controlled, the third control switch 23 is disconnected.

[0097] The second test instruction may refer to a test instruction generated when an EVCC signal function test is required. When the second test instruction is received, that is, when an EVCC signal function test is required, the fifth control switch 25 of the target control module 20 is controlled to be disconnected. At this time, the first control switch 21, the second control switch 22, and the fourth control switch 24 are still closed, the third control switch 23 is still disconnected, and the fifth control switch 25 is controlled to be disconnected.

[0098] Step S32 : receiving the first target data from the first communication unit 33 .

[0099] After the fifth control switch 25 is controlled to be disconnected, the first target data of the first communication unit 33 is received. The first target data is the whole vehicle target data of the electric vehicle. The first target data is used to indicate whether the test frame data of EVCC is obtained in the first communication unit 33. It can be understood that since the fifth control switch 25 is used to wake up the EVCC, when the fifth control switch 25 is closed, it means that the electric vehicle has entered the state of being ready to start or has been started (i.e., in the ACC mode); after the fifth control switch 25 is disconnected, the key ignition signal is disconnected, but since the electric vehicle has entered the running mode, the subsequent operation and work of the electric vehicle no longer depends on the key ignition signal. Therefore, after the fifth control switch 25 is disconnected, if the test frame data of EVCC can be obtained in the first communication unit 33, it means that the key ignition signal of the fifth control switch 25 successfully wakes up the EVCC test, and enters step S34; if the test frame data of EVCC is not obtained in the first communication unit 33, it means that the key ignition signal fails to wake up the EVCC test, and the EVCC test is abnormal, and enters step S33.

[0100] Step S33: In response to the first target data indicating that the test frame data is not acquired, generating a fifth test result.

[0101] When the first target data indicates that the test frame data is not acquired, that is, the EVCC test is abnormal, a fifth test result indicating that the EVCC test is abnormal is generated.

[0102] Step S34: In response to the first target data indicating that the test frame data is acquired, a sixth test result is generated.

[0103] When the first target data indicates that the test frame data is acquired, that is, the EVCC test is normal, a sixth test result indicating that the EVCC test is normal is generated.

[0104] In an embodiment of the present application, the charging test method controls the fifth control switch 25 of the target control module 20 to be disconnected in response to receiving a second test instruction, receives the first target data of the first communication unit 33, generates a fifth test result in response to the first target data indicating that the test frame data is not obtained, and generates a sixth test result in response to the first target data indicating that the test frame data is obtained, so as to implement the test of the key ignition signal of the fifth control switch 25.

[0105] In one embodiment, see Figure 7 , Figure 7 FIG. 4 is a flow chart of the fourth embodiment of the charging test method provided by the present application. Figure 7 As shown, in this embodiment, the charging test method includes the following steps:

[0106] Step S41 : in response to receiving the third test instruction, the first control switch 21 and the second control switch 22 of the target control module 20 are controlled to be closed.

[0107] Specifically, the third test instruction may be a test instruction generated in response to the electric vehicle being connected to the charging pile 71 through a slow charging gun after the key ignition signal test of the fifth control switch 25 is successfully performed. Upon receiving the third test instruction, the first control switch 21 and the second control switch 22 of the control target control module 20 are controlled to be closed. Among them, since the first control switch 21 and the second control switch 22 are both normally closed switches, the first control switch 21 and the second control switch 22 may not be substantially controlled upon receiving the third test instruction, so that the first control switch 21 and the second control switch 22 are kept in a closed state.

[0108] Step S42 : receiving the second analysis data from the waveform analyzer 31 .

[0109] Receive the second analysis data of the waveform analyzer 31. It can be understood that the second analysis data is the analysis data obtained when the waveform analyzer 31 analyzes the first communication signal CP, and the second analysis data includes the third state data of the first channel and the fourth state data of the second channel, and the third state data and the fourth state data can be represented by the duty cycle parameter and the amplitude parameter under the channel.

[0110] Step S43: In response to the second analysis data satisfying the fourth preset condition, generating a seventh test result.

[0111] Specifically, when the second analysis data meets the fourth preset condition, that is, the duty cycle parameter and auxiliary parameter of the third state data, and the duty cycle parameter and amplitude parameter of the fourth state data meet the fourth preset condition, it can be determined that the output of the CP path wire and the CP-OUT path wire is normal, that is, the output of the first communication signal CP is normal, and the electric vehicle can be charged in the first charging mode when interacting with the charging pile 71. At this time, the seventh test result is generated. Exemplarily, when the duty cycle parameter of the third state data is 80%-90% and the amplitude parameter is 6V, and the duty cycle parameter of the fourth state data is 80%-90% and the amplitude parameter is 6V, it is determined that the second analysis data meets the fourth preset condition.

[0112] Step S44: In response to the second analysis data not satisfying the fourth preset condition, generating an eighth test result.

[0113] When the second analysis data does not meet the fourth preset condition, that is, the duty cycle parameter and auxiliary parameter of the third state data, and the duty cycle parameter and amplitude parameter of the fourth state data do not meet the fourth preset condition, it can be determined that the output of the CP path wire and the CP-OUT path wire is abnormal, that is, the output of the first communication signal CP is abnormal, and the first charging mode of the electric vehicle is abnormal. At this time, the seventh test result is generated. In a possible implementation, when it is determined that the first charging mode of the electric vehicle is abnormal, the method of steps S21-S27 can be executed to locate the specific cause of the slow charging fault.

[0114] In the embodiment of the present application, the charging test method controls the first control switch 21 and the second control switch 22 of the target control module 20 to close in response to receiving the third test instruction, receives the second analysis data of the waveform analyzer 31, generates the seventh test result in response to the second analysis data satisfying the fourth preset condition, and generates the eighth test result in response to the second analysis data not satisfying the fourth preset condition. Therefore, the charging test method of the present embodiment can implement the test of the first communication signal of the first control switch 21 and the second control switch 22 in the above manner.

[0115] In one embodiment, see Figure 8 , Figure 8 FIG. 5 is a flow chart of the fifth embodiment of the charging test method provided by the present application. Figure 8 As shown, the analysis module 30 includes a voltage measurer 32, and the target data includes voltage measurement data of the voltage measurer 32. In this embodiment, the charging test method includes the following steps:

[0116] Step S51 : in response to receiving the fourth test instruction, the fourth control switch 24 of the control target control module 20 is controlled to be closed.

[0117] Specifically, the fourth test instruction may be a test instruction generated in response to the connection of the electric vehicle to the charging pile 71 through the fast charging gun after the first communication signal test of the first control switch 21 and the second control switch 22 is successful. Upon receiving the fourth test instruction, the fourth control switch 24 of the control target control module 20 is controlled to be closed. Since the fourth control switch 24 is a normally closed switch, the fourth control switch 24 may not be substantially controlled upon receiving the fourth test instruction, so that the fourth control switch 24 remains in a closed state.

[0118] Step S52 : receiving the voltage measurement data from the voltage measuring device 32 .

[0119] When the fourth control switch 24 is closed, since the voltage meter 32 is used to measure the voltage between the third terminal and the ground terminal of the fifth terminal of the second connection port 12, when the voltage measurement data of the voltage meter 32 is received, the voltage measurement data can be used to indicate whether the output of the wake_up path conductor is normal.

[0120] Step S53: In response to the voltage measurement data satisfying the fifth preset condition, generating a ninth test result.

[0121] Specifically, when the voltage measurement data meets the fifth preset condition, that is, the voltage measurement data is within the preset voltage range, it can be indicated that the output of the wake-up path conductor is within the normal range, and the electric vehicle can be charged in the second charging mode when interacting with the charging pile 71, and the second charging mode is the fast charging mode, so the ninth test result is generated. Exemplarily, the preset voltage range can be 11.5V to 12.5V, and when the voltage measurement data is between 11.5V and 12.5V, it can be determined that the voltage measurement data meets the fifth preset condition.

[0122] Step S54: In response to the voltage measurement data not satisfying the fifth preset condition, generating a tenth test result.

[0123] When the voltage measurement data is outside the preset voltage range, for example, the voltage measurement data is greater than 12.5V, or the voltage measurement data is less than 11.5V, it can be determined that the output of the wake_up path conductor is abnormal and the second charging mode of the electric vehicle is abnormal. At this time, the tenth test result is generated.

[0124] In the embodiment of the present application, the charging test method controls the fourth control switch 24 of the target control module 20 to close in response to receiving the fourth test instruction, receives the voltage measurement data of the voltage measurer 32, generates the ninth test result in response to the voltage measurement data satisfying the fifth preset condition, and generates the tenth test result in response to the voltage measurement data not satisfying the fifth preset condition. Therefore, the charging test method of the present embodiment can test the signal output of the wake_up path conductor of the fourth control switch 24 in the above manner. In a possible manner, the user can implement the EVCC signal test through the above steps S31-S34, S41-S44 and steps S51-S54. When the fifth control switch 25, the first control switch 21, the second control switch 22 and the fourth control switch 24 are all tested successfully, a related prompt of the success of the EVCC signal test can be further generated to realize the automatic signal test of the EVCC in the actual charging scenario of the electric vehicle, without manual supervision of data, and further improve the efficiency of the EVCC test.

[0125] In one embodiment, see Fig. 9 , Fig. 9 1 is a flow chart of the sixth embodiment of the charging test method provided by the present application. Fig. 9 As shown, in this embodiment, the charging test method includes the following steps:

[0126] Step S61 : in response to receiving the fifth test instruction, acquiring third analysis data of the waveform analyzer 31 of the analysis module 30 .

[0127] Specifically, the fifth test instruction may refer to a test instruction generated when a sleep test is required. Before the sleep test is performed, the electric vehicle needs to be in a power off mode (power off), and the electric vehicle is connected to the charging pile 71, and the charging test system is connected to the external power supply through the power supply module 60. When the fifth test instruction is received, the sleep condition data can be further obtained, and the sleep condition data includes at least the number of times the sleep test needs to be performed, such as a single sleep test or a cycle test, and the number of cycle tests. The sleep condition data may also include a preset sleep duration when the sleep determination is made, and the preset sleep duration indicates how long the first communication signal CP is output before entering sleep.

[0128] In response to receiving the fifth test instruction, the third analysis data of the waveform analyzer 31 is obtained. The third analysis data is the analysis data obtained when the waveform analyzer 31 analyzes the first communication signal CP. The third analysis data includes the fifth state data of the first channel. The fifth state data can be represented by the duty cycle parameter and amplitude parameter under the channel. Among them, the fifth test instruction is used to instruct the charging test system to perform a plug-in dormancy test. Plug-in dormancy can be understood as controlling the charging protocol converter 10 to enter dormancy after the duty cycle of the first communication signal CP continues to be an illegal duty cycle for a certain period of time.

[0129] Step S62: when the third analysis data meets the sixth preset condition, the first control switch 21 of the target control module 20 is controlled to be opened, and the first control switch 21 is controlled to be closed again.

[0130] After obtaining the third analysis data, it is determined whether the third analysis data meets the sixth preset condition, that is, whether the duty cycle parameter and amplitude parameter of the fifth state data of the first channel are preset thresholds. Exemplarily, it can be determined whether the duty cycle parameter of the fifth state data of the first channel is 100%, and whether the amplitude parameter of the fifth state data is 12V. When the third analysis data meets the sixth preset condition, that is, the duty cycle parameter of the fifth state data is 100% and the amplitude parameter is 12V, it can be determined that the charging protocol converter 10 is in the awake state, the first control switch 21 is controlled to be disconnected, and the first control switch 21 is controlled to be closed again.

[0131] Step S63 : receiving the second target data from the first communication unit 33 of the analysis module 30 .

[0132] After the first control switch 21 is opened and then closed again, the first control switch 21 can be reset and the second target data of the reset first communication unit 33 can be obtained. The second target data is used to indicate whether the first communication unit 33 obtains the EVCC test frame data.

[0133] Step S64: In response to the second target data indicating that the test frame data is acquired, timing is performed.

[0134] When the second target data indicates that the test frame data is acquired, that is, the first control switch 21 is reset successfully, timing is performed according to the first frame data in the test frame data.

[0135] Step S65: When the timed duration reaches the preset sleep duration, continue to obtain the third target data of the first communication unit 33 to determine whether the third target data indicates that the test frame data is obtained.

[0136] When the timing duration based on the test frame data reaches the preset sleep duration, that is, the first communication signal CP after the first control switch 21 is closed continues to be at an illegal duty cycle and reaches the preset sleep duration, at this time, the next frame of the third target data of the first communication unit 33 after reaching the preset sleep duration can continue to be obtained.

[0137] Step S66: If the third target data indicates that the test frame data is acquired, an eleventh test result of sleep failure is generated.

[0138] If the third target data indicates that the test frame data is obtained, it means that the first communication signal CP is still being output after the preset sleep time is reached, that is, the charging of the first charging mode controlled by the first control switch 21 is still in progress, and the charging protocol converter 10 is still in a working state after the preset sleep time is reached, and the plug-in sleep fails, then the eleventh test result of sleep failure is generated.

[0139] Step S67: If the third target data indicates that the test frame data is not obtained, a twelfth test result indicating successful sleep is generated.

[0140] If the third target data indicates that the test frame data is not obtained, it means that the first communication signal CP stops being output after the preset sleep time is reached, that is, the charging protocol converter 10 enters the plug-in sleep state after the preset sleep time is reached, and the twelfth test result of successful sleep is generated. If it is necessary to perform multiple sleep tests in a cycle, the number of tests can be recorded after the twelfth test result of successful sleep is generated, and when the number of tests does not reach the number of cycle tests indicated in the sleep condition data, the method can be returned to step S62 and steps S62-S67 can be continued until the test of the number of cycle tests indicated in the sleep condition data is completed.

[0141] In the embodiment of the present application, the charging test method obtains the third analysis data of the waveform analyzer 31 in response to receiving the fifth test instruction; when the third analysis data meets the sixth preset condition, controls the first control switch 21 to be disconnected, and controls the first control switch 21 to be reclosed; receives the second target data of the first communication unit 33 of the analysis module 30; in response to the second target data indicating that the test frame data is obtained, performs timing; when the timing duration reaches the preset sleep duration, continues to obtain the third target data of the first communication unit 33 to determine whether the third target data indicates that the test frame data is obtained; if the third target data indicates that the test frame data is obtained, then generates the eleventh test result of sleep failure; if the third target data indicates that the test frame data is not obtained, then generates the twelfth test result of sleep success. Therefore, the method of this embodiment can reset and time the first control switch 21 when it is determined that the charging protocol converter 10 is in the awake state, so as to determine whether the plug-in sleep test is successful through the third target data when the timing duration reaches the preset sleep duration, so as to realize the automated test of plug-in sleep, improve the efficiency of EVCC test, and improve the reliability of the charging test system.

[0142] Optionally, see Fig.10 , Fig.10 FIG. 1 is a flow chart of the seventh embodiment of the charging test method provided by the present application. Fig.10 As shown, after step S61, the charging test method further includes:

[0143] Step S68: when the third analysis data does not meet the sixth preset condition, the first control switch 21 is controlled to be disconnected, and the auxiliary source is controlled to output a high level signal to obtain the fourth target data of the first communication unit 33 of the analysis module 30 .

[0144] Specifically, when the third analysis data does not meet the sixth preset condition, that is, the duty cycle parameter of the fifth state data does not reach 100% and the amplitude parameter does not reach 12V, it can be determined that the charging protocol converter 10 has not yet awakened. The charging test method of this embodiment controls the first control switch 21 to be disconnected and turns on the auxiliary source, so as to realize the forced awakening of the charging protocol converter 10 by using the high-level signal output by the auxiliary source as the first communication signal CP. After using the high-level signal of the auxiliary source as the first communication signal CP, the fourth target data of the first communication unit 33 of the analysis module 30 is further obtained, and the fourth target data is similar to the second target data, and steps S63-S67 are performed to perform timing when the fourth target data indicates that the test frame data is obtained, and to determine whether the plug-in dormancy test is successful through the third target data when the timing duration reaches the preset dormancy duration, so as to realize the automatic test of plug-in dormancy through the forced awakening of the auxiliary source when the charging protocol converter 10 is not awakened, thereby improving the efficiency of the EVCC test.

[0145] The auxiliary source can be connected to the communication control module 40, and the communication control module 40 can be connected through the CP path wire between the auxiliary source and the first connection port 11 and the second connection port 12, so that the auxiliary source can output a high level signal as the first communication signal CP when the first control switch 21 is disconnected. If it is necessary to perform multiple cycles of sleep tests, the number of tests is recorded after the test of plug-in sleep is completed through the high level signal of the auxiliary source, and when the number of tests does not reach the number of cycle tests indicated in the sleep condition data, the auxiliary source is first controlled to stop outputting the high level signal, and the auxiliary source is controlled to output the high level signal again to achieve the reset of the high level signal of the auxiliary source, and the above steps are continued to be performed after the reset to cycle the test of plug-in sleep, and the specific cycle process is not repeated here.

[0146] In one embodiment, the target control module 20 includes a plurality of control switches, and the target data includes the fifth target data of the first communication unit 33. Fig.11 , Fig.11 1 is a flow chart of the eighth embodiment of the charging test method provided by the present application. Fig.11 As shown, in this embodiment, the charging test method includes the following steps:

[0147] Step S71: in response to receiving the sixth test instruction, controlling a switch to be tested among the plurality of control switches to be closed, and controlling other control switches except the switch to be tested to be opened.

[0148] Specifically, the switch to be tested among the plurality of control switches may be at least one of the first control switch 21, the second control switch 22, the third control switch 23, the fourth control switch 24, and the fifth control switch 25, and the other control switches except the switch to be tested are switches other than the current control switch to be tested. For example, when a wake-up stability test is required for the communication circuit of a single control switch in some test scenarios, a sixth test instruction may be generated, and in response to receiving the sixth test instruction, the switch to be tested among the plurality of control switches is controlled to be closed, and the other control switches except the switch to be tested are controlled to be opened, that is, only the switch to be tested is kept in a closed state.

[0149] Step S72: Control the switches to be tested to open and close in sequence according to the preset logic.

[0150] Specifically, controlling the switch to be tested to be opened and closed in sequence can be understood as controlling the switch to be tested to be opened, closed, opened, closed, opened, closed, etc. in sequence at a preset time interval according to a set logic. The set logic includes but is not limited to a pre-stored number of cycles of opening and closing of the switch to be tested, a preset time interval, a test time, etc.

[0151] Step S73 : receiving the fifth target data from the first communication unit 33 .

[0152] In the process of controlling the switches to be tested to be opened and closed in sequence according to the preset logic, the fifth target data of the first communication unit 33 is continuously received, and the fifth target data is used to indicate the change of the test frame data in the above control process.

[0153] Exemplarily, when the wake-up stability of the first control switch 21 needs to be tested, a signal generator can be connected to the first connection port 11 to simulate the waveform of the first communication signal CP, and the CP relays in several control switches are controlled to be closed and other relays are controlled to be disconnected, and the on and off of the CP relays are cyclically controlled to obtain the fifth target data. The fifth target data records whether the test frame data of the first communication unit 33 corresponds to being sent when the CP relay is closed, or corresponds to stopping sending when the CP relay is disconnected, so as to judge the stability of the CP relay during the wake-up process.

[0154] As another example, when the wake-up stability of the fifth control switch 25 needs to be tested, a signal generator can be connected to the first connection port 11 to simulate the waveform of the first communication signal CP, and the KL15 relays in several control switches are controlled to be closed and other relays are controlled to be disconnected, and the on and off of the KL15 relays are cyclically controlled to obtain the fifth target data. The fifth target data records whether the test frame data of the first communication unit 33 corresponds to being sent when the KL15 relay is disconnected, or corresponds to stopping sending when the KL15 relay is closed, so as to judge the stability of the KL15 relay during the wake-up process.

[0155] Step S74: in response to the fifth target data indicating that the test frame data of the switch to be tested does not change according to the preset logic, a thirteenth test result is generated.

[0156] When the fifth target data indicates that the test frame data of the switch to be tested does not change according to the preset logic, that is, the test frame data of the switch to be tested does not change according to the preset logic during the control process of the above preset logic, it means that the switch to be tested is not stably awakened during repeated multiple tests in the above control process, and the wake-up stability test fails, and the thirteenth test result is generated.

[0157] Step S75: In response to the fifth target data indicating that the test frame data changes according to a preset logic, a fourteenth test result is generated.

[0158] When the fifth target data indicates that the test frame data of the switch to be tested changes according to the preset logic, that is, the test frame data of the switch to be tested changes according to the preset logic during the control process of the above preset logic, it means that the switch to be tested can be stably awakened when the test is repeated multiple times during the above control process, and the wake-up stability test is successful, generating the fourteenth test result.

[0159] In the embodiment of the present application, the charging test method can control the switch to be tested among the plurality of control switches to be closed in response to receiving the sixth test instruction, and control the other control switches except the switch to be tested to be opened, and control the switches to be tested to be opened and closed in sequence according to the preset logic, receive the fifth target data of the first communication unit 33, and generate the thirteenth test result in response to the fifth target data indicating that the test frame data of the switch to be tested does not change according to the preset logic, and generate the fourteenth test result in response to the fifth target data indicating that the test frame data changes according to the preset logic. Therefore, the present embodiment can execute the control timing of the preset logic through the communication control module 40 to realize the wake-up stability test of the switch to be tested, so as to realize the wake-up stability test in the actual charging scenario of the electric vehicle, without manual supervision of data, and further improve the efficiency of the EVCC test.
