[0050] Various exemplary embodiments of the present disclosure will now be described in detail with reference to the accompanying drawings. It should be noted that the relative arrangement of components and steps, numerical expressions and numerical values ​​set forth in these embodiments do not limit the scope of the present disclosure unless otherwise specifically stated.

[0051] At the same time, it should be understood that for the convenience of description, the sizes of the various parts shown in the drawings are not drawn according to the actual proportional relationship.

[0052] The following description of at least one exemplary embodiment is merely illustrative in nature and is in no way intended to limit the present disclosure, its application, or uses.

[0053] Technologies, methods, and equipment known to ordinary technicians in the relevant art may not be discussed in detail, but where appropriate, the technologies, methods, and equipment should be considered as part of the specification.

[0054] In all examples shown and discussed herein, any specific values ​​should be interpreted as merely exemplary and not as limiting. Therefore, other examples of the exemplary embodiments may have different values.

[0055] It should be noted that like reference numerals and letters refer to similar items in the following figures, and therefore, once an item is defined in one figure, it need not be further discussed in subsequent figures.

[0056] In the related art, the evaluation of charging piles mainly depends on user feedback and data reported by charging piles. However, the evaluation method of charging piles based only on user feedback and data reported by charging piles is relatively one-sided, and the evaluation results are not accurate enough.

[0057] Figure 1A flow chart of a method for evaluating a charging pile according to some embodiments of the present disclosure is shown.

[0058] like Figure 1 As shown, the charging pile evaluation method includes steps S1 to S4. In some embodiments, the charging pile evaluation method is executed by a server in the cloud.

[0059] In step S1, abnormal event information of the charging pile is obtained from the vehicle-mounted electronic system; in step S2, the number of abnormal events occurring at the charging pile within a specified time is counted based on the abnormal event information; in step S3, the score of the charging pile is determined based on the number of abnormal events occurring at the charging pile within a specified time; in step S4, the score of the charging pile is pushed to at least one of the vehicle-mounted electronic system and the user device.

[0060] The vehicle electronic system includes, for example, a battery management system (BMS). During the vehicle charging process, the battery management system can detect and record abnormal event information of the charging pile and report it to the cloud server.

[0061] For a charging pile, the cloud server can accumulate the number of abnormal events that occur in the charging pile on a monthly basis.

[0062] Then, the cloud server updates the rating of the charging pile in real time according to the number of abnormal events, and pushes the rating to the vehicle electronic system and user devices. Users can view the rating of the charging pile on the display screen of the vehicle's human-computer interaction system. Users can also view the rating of the charging pile through the application of their own mobile terminal. By pushing the charging pile rating to users, users can be assisted in making personalized choices of charging piles.

[0063] According to some embodiments of the present disclosure, the evaluation method of the charging pile includes: obtaining abnormal event information of the charging pile from the vehicle electronic system; counting the number of abnormal events that occurred in the charging pile at a specified time according to the abnormal event information; determining the score of the charging pile according to the number of abnormal events that occurred in the charging pile at a specified time; and pushing the score of the charging pile to at least one of the vehicle electronic system and the user device. Through the collaboration of the vehicle side and the cloud, the charging pile can be scored more comprehensively and accurately according to the abnormal events recorded by the vehicle side.

[0064] In some embodiments, the score of the charging pile is determined based on the number of abnormal events that occur at the charging pile at a specified time, including: determining the score of the charging pile based on the number of abnormal events that occur at the charging pile at a specified time, the number of times the charging pile provides charging services at a specified time, and the total amount of electricity used by the charging pile to provide charging services at a specified time.

[0065] The number of times the charging service is provided and the total amount of electricity consumed by the charging service may be reported by the charging pile, for example.

[0066] In some embodiments, the score of the charging pile is determined according to the number of abnormal events that occur at the charging pile within a specified time, including: for each of multiple abnormal events, the score of the charging pile is determined according to the number of times each abnormal event occurs at the charging pile within a specified time and the weight of the abnormal event.

[0067] For example, for each abnormal event, the number of occurrences is counted separately, and a weight is set for each abnormal event. The score of the charging pile is determined by multiplying the number of times each abnormal event occurs at the charging pile at a specified time by the weight of the abnormal event.

[0068] In some embodiments, the abnormal event includes at least one of the following: a charging failure event; an actual charging current higher than the rated current event; an actual charging power does not match the target power event; an abnormal interruption of the charging process event; an actual charging current does not change with the target current event; and an insulation failure event in the charging pile.

[0069] For example, the BMS needs to record the following information during each charging process.

[0070] Abnormal (1): Charging failure event, such as failure to enter charging mode, which may be caused by national standard communication failure or charging pile startup failure;

[0071] Abnormal (2): The actual charging current is higher than the rated current event, that is, charging overcurrent. The BMS will record a long-term overcurrent fault;

[0072] Abnormal (3): The actual charging power does not match the target power, where the target power is the power requested by the BMS. For example, the actual output power of the charging pile does not match the power requested by the BMS, such as the actual output current of the charging pile is less than the current requested by the BMF.

[0073] Abnormal (4): abnormal interruption of the charging process, for example, charging gun tripping. The abnormal cause may be a Controller Area Network (CAN) communication failure or a charging terminal failure. It may also be other unknown reasons that cause the charging terminal to end.

[0074] Abnormal (5): The actual charging current does not change with the target current, that is, the current output of the charging pile is slow to respond. The BMS will compare the actual charging current with the current requested by the BMS. If it finds that the two do not match, it will record the time, amplitude and other information of the mismatch. The BMS can also record short-term overcurrent or current non-following faults.

[0075] Abnormal (6): Insulation failure of the charging pile. Insulation failure of the charging pile means that insulation damage has occurred in the electrical system of the charging pile, which may cause leakage or other safety hazards. The BMS can record whether insulation failure has occurred at the end of the charging pile.

[0076] The above-mentioned abnormalities reflect the operating status and quality information of the charging pile, which is difficult to detect comprehensively. Therefore, the above-mentioned abnormalities are recorded and reported by the vehicle side, which can evaluate the charging pile more comprehensively and in real time, and help to accurately judge the quality and potential risks of the charging pile, thereby improving the user experience and battery charging safety.

[0077] In some embodiments, the charging pile evaluation method further includes: obtaining at least one of the identification and location information of the charging pile from the vehicle-mounted electronic system.

[0078] For example, the onboard controller (BMS) records the following information during each charging process: the number of the charging pile, the GPS information of the charging pile, and reports this information to the cloud after associating it with the abnormal event information.

[0079] In some embodiments, for each abnormal event of multiple abnormal events, the score of the charging pile is determined according to the number of times each abnormal event occurs at the charging pile at a specified time and the weight of the abnormal event, including at least one of the following: determining the efficiency score of the charging pile according to the number of events where the actual charging power does not match the target power, the weight of the event where the actual charging power does not match the target power, the number of events where the actual charging current does not change with the target current, and the weight of the event where the actual charging current does not change with the target current; determining the efficiency score of the charging pile according to the number of events where the actual charging current is higher than the rated current, the weight of the event where the actual charging current is higher than the rated current, the number of events where the actual charging current does not change with the target current, the weight of the event where the actual charging current does not change with the target current, and the charging pile. The safety score of the charging pile is determined based on the number of insulation failure events and the weight of the insulation failure events. The availability score of the charging pile is determined based on the number of charging failure events, the weight of the charging failure events, the number of abnormal charging interruption events, the weight of the abnormal charging interruption events, the number of insulation failure events of the charging pile, and the weight of the insulation failure events of the charging pile. The stability score of the charging pile is determined based on the number of abnormal charging interruption events, the weight of the abnormal charging interruption events, the number of charging services provided by the charging pile at a specified time, and the total amount of charging services provided by the charging pile at a specified time. The score of the charging pile is determined based on the efficiency score, safety score, availability score, and stability score.

[0080] For example, for each charging pile, a score is assigned based on the various types of anomalies that occur (such as efficiency anomalies, safety anomalies, and availability anomalies). For each anomaly, the scoring weight of the anomaly is determined based on its correlation with a certain dimension. The cloud collects the abnormal information of the charging piles and further accumulates, integrates, and analyzes it on a monthly basis.

[0081] The cloud can be counted according to the following dimensions.

[0082] First, we introduce the method of calculating the efficiency score.

[0083] Vehicle-side abnormality (3) number of occurrences * 2 points

[0084] Vehicle-side abnormality (5) number of occurrences * 2 points

[0085] Efficiency evaluation level: A (0-1000 points), B (1000-10000 points), C (10000 and above)

[0086] For example, if a charging pile has "vehicle-side problem 3 and vehicle-side problem 5" less than 500 times within a month, its efficiency score will be A.

[0087] The following describes how the safety score is calculated.

[0088] Safety score = number of occurrences of vehicle-side abnormality (2) * 3 points + number of occurrences of vehicle-side abnormality (5) * 1 point + number of occurrences of vehicle-side abnormality (6) * 2 points

[0089] Safety evaluation level: A (0-1000 points), B (1000-10000 points), C (10000 points and above)

[0090] The following describes how the availability score is calculated.

[0091] Availability score = number of occurrences of vehicle-side anomaly (1) * 3 points + number of occurrences of vehicle-side anomaly (4) * 2 points + number of occurrences of vehicle-side anomaly (6) * 2 points

[0092] Usability evaluation level: A (0-1000 points), B (1000-10000 points), C (10000 points and above)

[0093] The following describes how the stability score is calculated.

[0094] Stability score = charging times of the charging pile * 2 points + (total charging power / 10 kwh) * 0.1 points + abnormal charging end count * (-1) points

[0095] Stability evaluation level: A (500 points or more), B (250 points to 500 points), C (50 points to 250 points), D (less than 50 points)

[0096] The scores of the same charging pile in the same month are progressively accumulated. According to the accumulated scores of each dimension, the total grade score of each charging pile (such as A, B, C, D grade) is determined, as shown in Table 1.

[0097] Table 1

[0098] stability efficiency Safety Available Overall level >＝B A A A A+ >＝B B A A A >＝C A A B B+ >＝C >＝C B A B >＝C >＝C B B B- >＝D >＝C C >＝B C >＝D >＝C C C D

[0099] In some embodiments, the efficiency score, safety score, availability score and stability score are pushed to at least one of the vehicle electronic system and the user device. Through the evaluation of multiple dimensions, the user can be provided with detailed quality information of the charging pile, including efficiency, safety, availability and stability.

[0100] In some embodiments, the scoring of charging piles includes the first level, the second level and the third level, and the evaluation method of the charging piles also includes: pushing the recommendation information of the first level charging piles to at least one of the vehicle electronic system and the user device; pushing the risk warning for the second level charging piles to at least one of the vehicle electronic system and the user device; pushing the disabling warning for the third level charging piles to at least one of the vehicle electronic system and the user device.

[0101] For example, A+ and A in Table 1 are taken as the first level, B+, B, B- as the second level, and C and D as the third level. Through the vehicle electronic system and user equipment, the first-level charging pile is recommended to the user first, and the second-level charging pile is prompted that there are risks, and the user is not recommended to choose the third-level charging pile. By prompting the second-level charging pile to have risks and not recommending the user to choose the third-level charging pile, the overcurrent of charging can be reduced, the risk of the charging process can be reduced, and the battery safety can be improved. The cloud can also provide personalized charging pile quality information according to the evaluation level, different vehicle models and charging needs.

[0102] In some embodiments, the charging pile evaluation method further includes: reducing the target power of the second-level charging pile.

[0103] For example, for charging piles of Class B and below, with the user's consent, the charging power requested by the BMS can be limited to 75% of the original, and the current can be monitored by the BMS and the charging allowable current can be reduced in advance. By limiting the charging power of low-quality charging piles, overcurrent can be reduced, the risk of the charging process can be reduced, battery safety can be improved, and battery life can be extended. The cloud can also provide personalized charging pile quality information based on the evaluation level, different vehicle models and charging needs.
