DETAILED DESCRIPTION
[0022] Embodiments of the present application are described in detail below with reference to the accompanying drawings, in which like or similar elements or components are denoted throughout by like reference characters, and further where appropriate, the embodiments described below are merely examples that are intended to explain the present application and are not to be understood as limiting to the present application.
[0023] The plug-and-charge function test method, device, equipment, medium and program product of the embodiments of the present application are described below with reference to the accompanying drawings. In view of the problems of the related art that the plug-and-charge function test relies on manual or semi-automatic operation, has low efficiency and insufficient coverage, the present application provides a plug-and-charge function test method, in which, when it is determined that communication is established between a vehicle and a charging pile, the present application embodiment detects whether the vehicle receives a PWM signal satisfying a preset encoding rule sent by the charging pile; when the vehicle receives the PWM signal satisfying the preset encoding rule, the number of times of receiving the PWM signal satisfying the preset encoding rule by the vehicle is obtained, and a final test result is obtained according to the number of times of receiving and / or the verification result of each time of the PWM signal satisfying the preset encoding rule. Thus, by simulating the communication between the charging pile and the vehicle-mounted controller, simulating the plug-in action and verifying the interaction process, the problems of the related art that the plug-and-charge function test relies on manual or semi-automatic operation, has low efficiency and insufficient coverage are solved, the test efficiency is improved, and the repeatability and reliability of the test process are enhanced.
[0024] Specifically,Figure 1 A flowchart of a plug-and-charge function test method provided by an embodiment of the present application.
[0025] As shown in the figure, Figure 1 the plug-and-charge function test method includes the following steps: In step S101, it is determined whether communication is established between the vehicle and the charging pile. Specifically, after the charging gun is connected, whether communication is established between the vehicle and the charging pile can be determined by the following methods, including but not limited to: detecting whether the CP (Control Pilot) signal voltage is a standard voltage (for example, 9V), confirming that the vehicle PDCU (Power Distribution Control Unit) controller has been woken up and is in a working state; checking whether the vehicle and the charging pile have completed a handshake protocol, including message interaction, identity authentication and charging parameter negotiation; if the PDCU analysis is correct and the protocol interaction is correct, the system enters the plug-and-charge process; otherwise, it is degraded to a normal slow charging mode; the test device automatically determines whether the communication is successfully established by comparing the real-time collected communication data with the expected results.
[0026] In step S102, in the case that communication is established between the vehicle and the charging pile, it is detected whether the vehicle receives a PWM signal sent by the charging pile and satisfying a preset encoding rule.
[0027] Specifically, after the vehicle and the charging pile successfully establish a communication connection, the vehicle PDCU controller will monitor the PWM (Pulse Width Modulation) signal sent by the charging pile through the CP line in real time, detect whether its key parameters meet the preset encoding rule, including a frequency of 1kHz±3%, a duty cycle of 5%±0.5% and an amplitude of 9V±0.5V; the controller will decode the signal, count the number of PWM wave periods and verify whether the duration matches the encoding rule (for example, 10 periods / 10ms corresponding to the number 1, 20 periods / 20ms corresponding to the number 2, etc.); at the same time, the system will check the continuous reception of the signal; for the PWM signal that does not meet the preset encoding rule (such as a too large frequency deviation, a wrong duty cycle or an abnormal amplitude), the controller will refuse to receive and record the error type; based on the signal characteristics, decoding accuracy and reception stability, it is determined whether the vehicle successfully receives and correctly identifies the PWM signal that meets the preset encoding rule.
[0028] It should be noted that, as shown in the figure, Figure 2 Figure 2 A schematic diagram of the CP coding rule of the plug-and-charge function test method of an embodiment of the present application; the preset coding rule is represented by the number of PWM waves with a frequency of 1 KHZ and a duty cycle of 5%, and is specifically expressed as follows: number 1: 10 cycles of PWM waves with a frequency of 1 KHZ and a duty cycle of 5%, a duration of 10 ms; number 2: 20 cycles of PWM waves with a frequency of 1 KHZ and a duty cycle of 5%, a duration of 20 ms; number 3: 30 cycles of PWM waves with a frequency of 1 KHZ and a duty cycle of 5%, a duration of 30 ms; number 4: 40 cycles of PWM waves with a frequency of 1 KHZ and a duty cycle of 5%, a duration of 40 ms; number 5: 50 cycles of PWM waves with a frequency of 1 KHZ and a duty cycle of 5%, a duration of 50 ms; number 6: 60 cycles of PWM waves with a frequency of 1 KHZ and a duty cycle of 5%, a duration of 60 ms; number 7: 70 cycles of PWM waves with a frequency of 1 KHZ and a duty cycle of 5%, a duration of 70 ms; number 8: 80 cycles of PWM waves with a frequency of 1 KHZ and a duty cycle of 5%, a duration of 80 ms; number 9: 90 cycles of PWM waves with a frequency of 1 KHZ and a duty cycle of 5%, a duration of 90 ms; number 0: 100 cycles of PWM waves with a frequency of 1 KHZ and a duty cycle of 5%, a duration of 100 ms.
[0029] In step S103, if the vehicle receives the PWM signal satisfying the preset coding rule, the number of times of receiving the PWM signal satisfying the preset coding rule is obtained, and the final test result is obtained according to the number of times of receiving and / or the verification result of each time of the PWM signal satisfying the preset coding rule. Specifically, when the vehicle successfully receives the PWM signal satisfying the preset coding rule, the system records the number of valid receptions, and verifies each received signal; the system comprehensively analyzes the number of reception statistics and single verification result (including signal parameter accuracy, decoding correctness and other dimensions) to automatically generate the final test result, and records detailed test data for subsequent analysis; based on the double judgment mechanism of the number of receptions and the verification result, the test rigor is ensured, and the intermittent communication problem can be effectively identified.
[0030] Optionally, in some embodiments, the final test result is obtained according to the number of times of receiving and / or the verification result of each time of the PWM signal satisfying the preset coding rule, including: judging whether the number of times of receiving is a preset number of times; if the number of times of receiving is the preset number of times, the final test result is determined to be verified when the verification results of the preset number of times are all correct, or there is only one error in the verification results of the preset number of times.
[0031] The preset number of times can be a threshold value preset by a user, a threshold value obtained through a limited number of experiments, or a threshold value obtained through a limited number of computer simulations, and is not limited herein.
[0032] It can be understood that, if the number of times meets the number of times requirement or there is an individual error (for example, one error in three times), the system can still determine that the verification is passed; but if the number of errors exceeds the preset number of times (for example, two or more errors in three times), the verification is determined to fail. Through double verification, it is ensured that the test result meets the rigor of the standard requirement and can adapt to the reasonable error that can occur in actual communication to determine the final test result to pass.
[0033] Optionally, in some embodiments, after determining that the number of times of receiving is the preset number of times, the method further includes: determining whether the PWM signals in the verification results of the preset number of times are within the preset error range; and if the PWM signals in the verification results of the preset number of times are all within the preset error range, determining that the final test result is verification passed.
[0034] Optionally, in some embodiments, after determining whether the PWM signals in the verification results of the preset number of times are within the preset error range, the method further includes: if any of the PWM signals in the verification results of the preset number of times is not within the preset error range, determining that the final test result is verification failed.
[0035] The preset error range can be a threshold value preset by a user, a threshold value obtained through a limited number of experiments, or a threshold value obtained through a limited number of computer simulations, and is not limited herein.
[0036] It can be understood that, only when all the received signals meet the error range requirement, the verification is determined to pass; otherwise, as long as there is a signal exceeding the allowed error range, the verification is immediately determined to fail, which improves the rigor of the test and can accurately identify the case of unstable signal quality, and ensures that only the signal completely meeting the technical specification can pass the verification.
[0037] Optionally, in some embodiments, after determining whether the number of times of receiving is the preset number of times, the method further includes: if the number of times of receiving is not the preset number of times, determining that the final test result is verification failed.
[0038] It can be understood that, if the number of times of actually received PWM signals does not meet the preset number of times, the system directly determines that the final test result is verification failed, effectively identifies the basic problems such as communication link interruption and unstable signal transmission, and avoids subsequent invalid error analysis; this determination standard and the error range verification together constitute a complete test evaluation system, which ensures that only the signal completely meeting the number of times requirement and parameter standard can pass the verification.
[0039] Therefore, the embodiments of the present application improve the test efficiency and consistency, reduce manual intervention; and support multiple protocols and vehicle model adaptation, have strong compatibility; can automatically generate a report, facilitating later tracing and analysis; and can be deployed in the controller development stage, improving the development efficiency.

In this way, by simulating the communication between the charging pile and the vehicle-mounted controller, simulating the gun insertion action and verifying the interaction process, the problems in the related art, such as the dependence of the plug-and-charge function test on manual or semi-automatic operation, low efficiency and insufficient coverage, are solved, the test efficiency is improved, and the repeatability and reliability of the test process are enhanced.
