[0051] The names of the messages or information exchanged between multiple devices in the embodiments of this disclosure are only for illustrative purposes and are not used to limit the scope of these messages or information. It can be understood that before using the technical solutions disclosed in the embodiments of this disclosure, the types, usage scopes, usage scenarios, etc. of the personal information involved in this disclosure should be informed to users and the authorization of users should be obtained in an appropriate manner in accordance with relevant laws and regulations.

[0052] First, the application scenarios of this disclosure are described. When an electric vehicle comes off the production line, it generally needs to undergo off-line inspection to detect whether the key functions of the vehicle are normal. The functions mainly consist of two parts: software and hardware. For each automotive hardware, due to factors such as tolerance and integration process, it is unique when it is manufactured. Coupled with the differences caused by factors such as environment, transportation, aging, and assembly, there may be individual failures of parts in a very small number of vehicles after the vehicle is assembled, such as: low-voltage circuit faults, wire harness solder joint disconnection, wire harness insulation failure due to skin breakage, etc.

[0053] Currently, in the industry, there are not only electric vehicles equipped with the DC charging protocol of the old national standards (GB / T 27930-2015, GB / T 18487.1-2015) (hereinafter referred to as the old national standards), but also electric vehicles equipped with the DC charging protocol of the new national standards (GB / T27930-xxxx, GB / T 18487.1-xxxx) (hereinafter referred to as the new national standards). At the same time, many automobile enterprises have not only developed low-voltage platform vehicles (such as 400V models), but also high-voltage platform vehicles (such as 800V models). However, there are three mainstream charging pile voltage platforms of 500V, 750V, and 1000V on the market. 400V models can be directly charged on all charging piles, and only a direct charging circuit needs to be configured. For 800V models, in addition to the direct charging circuit, in order to be able to charge on 500V and 750V charging piles, 800V models usually carry a boost charging circuit. Therefore, for such models, in addition to testing whether the direct charging circuit is normal, it is also necessary to test whether the boost charging circuit is normal.

[0054] The applicant has found that electric vehicles equipped with the DC charging protocol of the new national standards generally also need to be compatible with charging piles of the DC charging protocol of the old national standards for charging. In addition to testing whether the low-voltage communication line of the new national standards is normal, it is also necessary to test whether the low-voltage communication line of the old national standards is normal. Therefore, the off-line detection situation of the vehicle becomes quite complicated and the detection time is relatively long. In a related technology, the data of the charging line detection method for old national standard vehicles can be seen in Table 1:

[0055] Table 1

[0056]

[0057] For the direct charging high-voltage circuit of the vehicle, between the high-voltage battery and the vehicle charging socket, there are only positive and negative charging relays. For the boost charging high-voltage circuit, between the high-voltage battery and the vehicle charging socket, there are not only positive and negative charging relays, but also a booster. In the charging test process, only the charging relay is closed for the direct charging high-voltage circuit, while for the boost charging high-voltage circuit in the charging test process, not only the charging relay needs to be closed, but also the booster needs to be started to raise the low voltage to charge the battery. If we want to complete the detection of the hardware states of the two high-voltage circuits without the vehicle executing the DC charging process, there are significant differences: a. To detect the direct charging high-voltage circuit, only need to control the charging relay to close, and then measure the voltage at the charging port through the device to detect the hardware state of the direct charging high-voltage circuit; b. If we want to detect the state of the boost charging high-voltage circuit, not only the closing of the charging relay needs to be controlled, and because the booster is a power device and the boost charging function needs to be executed to verify the hardware state, but also a power supply needs to be provided to start the booster for charging.

[0058] It can be seen that the current off-line detection scheme for vehicles has certain limitations. The test cases and scenarios are relatively single, and the detection speed is slow, seriously affecting the production rhythm and production capacity efficiency of vehicle manufacturers. Therefore, there is an urgent need for a new vehicle detection method and system. The present disclosure will be described below in conjunction with specific embodiments.

[0059] Figure 1 is a flowchart of a vehicle detection method shown according to an exemplary embodiment. As Figure 1 shown, the embodiments of the present disclosure provide a vehicle detection method, which may include the following steps:

[0060] In step S10, obtain the charging type of the vehicle to be detected; the charging type includes: the first vehicle model, the second vehicle model, the third vehicle model, and the fourth vehicle model. The first vehicle model and the second vehicle model correspond to the first charging standard, and the third vehicle model and the fourth vehicle model correspond to the second charging standard.

[0061] In this step, obtain the charging type of the vehicle to be detected; the charging type includes: the first vehicle model, the second vehicle model, the third vehicle model, and the fourth vehicle model. The first vehicle model and the second vehicle model correspond to the first charging standard, and the third vehicle model and the fourth vehicle model correspond to the second charging standard. Exemplarily, the first charging standard may be the DC charging protocol of the old national standard, the second charging standard may be the DC charging protocol of the new national standard, the first vehicle model may be an old national standard 400V vehicle model, the second vehicle model may be an old national standard 800V vehicle model, the third vehicle model may be a new national standard 400V vehicle model, and the fourth vehicle model may be a new national standard 800V vehicle model.

[0062] In step S20, according to the charging type, determine the detection device corresponding to the target charging line of the vehicle, and detect the target charging line through the detection device. Wherein, the target charging line includes at least one of the direct charging high-voltage circuit, the boost charging high-voltage circuit, the low-voltage communication line of the first charging standard, and the low-voltage communication line of the second charging standard of the vehicle.

[0063] In this step, according to the charging type, the detection device corresponding to the target charging line of the vehicle is determined, and the target charging line is detected by the detection device. Among them, the target charging line includes at least one of the direct charging high-voltage circuit, boost charging high-voltage circuit, low-voltage communication line of the first charging standard, and low-voltage communication line of the second charging standard of the vehicle. Exemplarily, for old national standard 400V models, only the direct charging 400V high-voltage circuit and the old national standard low-voltage communication line need to be tested for normality, while for new national standard 800V models, not only the direct charging 800V high-voltage circuit and the new national standard low-voltage communication line need to be tested for normality, but also the boost charging high-voltage circuit and the old national standard low-voltage communication line need to be tested for normality. This requires configuring appropriate test charging piles and test tools to meet the test requirements of the charging lines of different models while minimizing the test time to improve efficiency and production capacity.

[0064] In summary, the embodiments of the present disclosure provide a vehicle detection method, including: obtaining the charging type of the vehicle to be detected; the charging type includes: the first model, the second model, the third model, and the fourth model, the first model and the second model correspond to the first charging standard, and the third model and the fourth model correspond to the second charging standard; according to the charging type, determining the detection device corresponding to the target charging line of the vehicle, and detecting the target charging line through the detection device; where the target charging line includes at least one of the direct charging high-voltage circuit, boost charging high-voltage circuit, low-voltage communication line of the first charging standard, and low-voltage communication line of the second charging standard of the vehicle. The embodiments of the present disclosure can improve the off-line detection speed of electric vehicles with different charging protocol standards and voltage levels, thereby improving the production rhythm and production capacity.

[0065] Figure 2 is a flowchart of a vehicle detection method shown according to an exemplary embodiment. As Figure 2 shown, the step of determining the detection device corresponding to the target charging line of the vehicle according to the charging type and detecting the target charging line through the detection device may include the following steps:

[0066] In step S201, when the charging type of the vehicle is the first model, the direct charging high-voltage circuit and the low-voltage communication line of the first charging standard are detected by the first charging pile or the second charging pile, the maximum output voltage of the first charging pile is greater than the maximum output voltage of the second charging pile, and the maximum output voltage of the second charging pile is greater than the charging voltage of the battery of the first model.

[0067] In this step, when the charging type of the vehicle is the first vehicle model, the direct charging high-voltage circuit and the low-voltage communication line of the first charging standard are detected through the first charging pile or the second charging pile. The maximum output voltage of the first charging pile is greater than that of the second charging pile, and the maximum output voltage of the second charging pile is greater than the charging voltage of the battery of the first vehicle model. Exemplarily, the first charging pile can be an old national standard 1000V charging pile, and the second charging pile can be an old national standard 500V charging pile or an old national standard 750V charging pile. The first vehicle model can be an old national standard 400V vehicle model.

[0068] Figure 3 is a flowchart of a vehicle detection method shown according to an exemplary embodiment. As Figure 3 shown, determining the detection device corresponding to the target charging line of the vehicle according to the charging type and detecting the target charging line through the detection device may include the following steps:

[0069] In step S202, when the charging type of the vehicle is the second vehicle model, the boost charging high-voltage circuit and the low-voltage communication line of the first charging standard are detected through the second charging pile.

[0070] In this step, when the charging type of the vehicle is the second vehicle model, the boost charging high-voltage circuit and the low-voltage communication line of the first charging standard are detected through the second charging pile. Exemplarily, the second vehicle model can be an old national standard 800V vehicle model, and the second charging pile can be an old national standard 500V charging pile or an old national standard 750V charging pile.

[0071] In step S203, the direct charging high-voltage circuit is detected through a circuit detection tool, where the maximum output voltage of the second charging pile is less than the charging voltage of the battery of the second vehicle model, and the charging voltage of the battery of the second vehicle model is greater than the charging voltage of the battery of the first vehicle model.

[0072] In this step, the direct charging high-voltage circuit is detected through a circuit detection tool, where the maximum output voltage of the second charging pile is less than the charging voltage of the battery of the second vehicle model, and the charging voltage of the battery of the second vehicle model is greater than the charging voltage of the battery of the first vehicle model. Exemplarily, the circuit detection tool can be an instrument or meter for detecting the continuity of a circuit, such as a voltmeter or an ammeter, and a multimeter, etc. Of course, other circuit detection tools can also be used, and the present disclosure does not limit this here. If an old national standard 1000V charging pile is used to test the direct charging 800V high-voltage circuit, the old national standard low-voltage communication line will also need to be repeatedly tested, wasting the test time. In this way, compared with directly using an old national standard 1000V charging pile to test the direct charging 800V high-voltage circuit, the test time of the direct charging 800V high-voltage circuit can be reduced, and the test efficiency and production capacity can be improved.

[0073] Exemplarily, the data of the charging line detection method for old national standard vehicles optimized by the above vehicle detection method can be seen in Table 2:

[0074] Table 2:

[0075]

[0076] It can be clearly seen from Table 2 that since the direct charging high-voltage circuit is directly detected by a circuit test tool, it only takes 10 seconds, which is much less than the 60 seconds required for charging pile detection. Detecting the direct charging high-voltage circuit alone is relatively simple and efficient, which can significantly reduce the test time and improve the detection efficiency.

[0077] Referring to Table 1 and Table 2 mentioned above, the detection time for the old national standard 800V vehicle model in the prior art is 120 seconds, while the detection time for the old national standard 800V vehicle model using the improved method of this embodiment is only 70 seconds. Each vehicle saves 50 seconds of detection time, which greatly improves the offline detection efficiency of the vehicle and thus improves the production capacity.

[0078] Figure 4 It is a flowchart of a vehicle detection method shown according to an exemplary embodiment. As Figure 4 shown, determining the detection device corresponding to the target charging line of the vehicle according to the charging type and detecting the target charging line through the detection device may include the following steps:

[0079] In step S204, when the charging type of the vehicle is the second vehicle model, the direct charging high-voltage circuit and the low-voltage communication line of the first charging standard are detected through the first charging pile, where the maximum output voltage of the first charging pile is greater than the charging voltage of the battery of the second vehicle model.

[0080] In this step, when the charging type of the vehicle is the second vehicle model, the direct charging high-voltage circuit and the low-voltage communication line of the first charging standard are detected through the first charging pile, where the maximum output voltage of the first charging pile is greater than the charging voltage of the battery of the second vehicle model. Exemplarily, the second vehicle model may be an old national standard 800V vehicle model, and the first charging pile may be an old national standard 1000V charging pile.

[0081] Figure 5 It is a flowchart of a vehicle detection method shown according to an exemplary embodiment. As Figure 5 shown, determining the detection device corresponding to the target charging line of the vehicle according to the charging type and detecting the target charging line through the detection device may include the following steps:

[0082] In step S205, when the charging type of the vehicle is the third vehicle model, the direct charging high-voltage circuit and the low-voltage communication line of the first charging standard are detected through the first charging pile or the second charging pile. The maximum output voltage of the second charging pile is greater than the charging voltage of the battery of the third vehicle model, and the maximum output voltage of the first charging pile is greater than the maximum output voltage of the second charging pile.

[0083] In this step, when the charging type of the vehicle is the third vehicle model, the direct charging high-voltage circuit and the low-voltage communication line of the first charging standard are detected through the first charging pile or the second charging pile. The maximum output voltage of the second charging pile is greater than the charging voltage of the battery of the third vehicle model, and the maximum output voltage of the first charging pile is greater than the maximum output voltage of the second charging pile. Exemplarily, the third vehicle model can be a new national standard 400V vehicle model, and the direct charging 400V high-voltage circuit and the low-voltage communication line of the old national standard can be detected through an old national standard 1000V charging pile, an old national standard 750V charging pile, or an old national standard 500V charging pile.

[0084] In the related art, the data of the charging line detection method for new national standard vehicles can be seen in Table 3:

[0085] Table 3:

[0086]

[0087]

[0088] The data of the charging line detection method for new national standard vehicles improved by the above vehicle detection method can be seen in Table 4:

[0089] Table 4:

[0090]

[0091] It can be seen from the data comparison between Table 3 and Table 4 above that the off-line detection time of the new national standard 800V vehicle model using the improved detection method is 120 seconds, while the off-line detection time of the new national standard 800V vehicle model in the prior art is 240 seconds. Obviously, it can be seen that using the improved detection method in this embodiment greatly improves the off-line detection efficiency of the vehicle, thereby improving the production capacity.

[0092] Figure 6 is a flowchart of a vehicle detection method shown according to an exemplary embodiment. As Figure 6 shown, determining the detection device corresponding to the target charging line of the vehicle according to the charging type and detecting the target charging line through the detection device may include the following steps:

[0093] In step S206, when the charging type of the vehicle is the third vehicle model, the direct charging high-voltage circuit and the low-voltage communication line of the second charging standard are detected through the third charging pile or the fourth charging pile, where the maximum output voltage of the third charging pile is greater than the maximum output voltage of the fourth charging pile, the maximum output voltage of the fourth charging pile is greater than the charging voltage of the battery of the third vehicle model, and the charging voltage of the battery of the third vehicle model is equal to the charging voltage of the battery of the first vehicle model.

[0094] In this step, when the charging type of the vehicle is the third vehicle model, the direct charging high-voltage circuit and the low-voltage communication line of the second charging standard are detected through the third charging pile or the fourth charging pile, where the maximum output voltage of the third charging pile is greater than the maximum output voltage of the fourth charging pile, the maximum output voltage of the fourth charging pile is greater than the charging voltage of the battery of the third vehicle model, and the charging voltage of the battery of the third vehicle model is equal to the charging voltage of the battery of the first vehicle model. Exemplarily, the third charging pile can be a new national standard 1000V charging pile, and the fourth charging pile can be a new national standard 500V charging pile or a new national standard 750V charging pile. The direct charging 400V high-voltage circuit and the low-voltage communication line of the new national standard can be detected through the new national standard 1000V charging pile, the new national standard 750V charging pile or the new national standard 500V charging pile.

[0095] Figure 7 is a flowchart of a vehicle detection method shown according to an exemplary embodiment. As Figure 7 shown, determining the detection device corresponding to the target charging line of the vehicle according to the charging type and detecting the target charging line through the detection device may include the following steps:

[0096] In step S207, when the charging type of the vehicle is the fourth vehicle model, the direct charging high-voltage circuit and the low-voltage communication line of the second charging standard are detected through the third charging pile, and the maximum output voltage of the third charging pile is greater than the charging voltage of the battery of the fourth vehicle model.

[0097] In this step, when the charging type of the vehicle is the fourth vehicle model, the direct charging high-voltage circuit and the low-voltage communication line of the second charging standard are detected through the third charging pile, and the maximum output voltage of the third charging pile is greater than the charging voltage of the battery of the fourth vehicle model.
