[0078] Considering that in the process of identifying and obtaining the vehicle VIN code, there may be situations where the VIN code cannot be identified due to different parking locations, it is necessary to further analyze and judge the identification and acquisition of the vehicle VIN code. Figure 2 The illustrated embodiment is described in detail.

[0079] Reference Figure 2 , identifying and obtaining the vehicle VIN code includes:

[0080] Step S110, identifying and acquiring the relative position of the vehicle with respect to the charging pile.

[0081] Among them, the process of identifying and obtaining the relative position of the vehicle with respect to the charging pile is as follows: obtain the center of gravity position of the vehicle and the location of the charging pile, and then based on the center of gravity position of the vehicle and the location of the charging pile, the relative position of the vehicle with respect to the charging pile can be formed.

[0093] Step S142.4, maintain the existing processing method unchanged.

[0094] exist Figure 1 In step S200, it is necessary to consider that the DC charging information of the vehicle may be affected by the external environment temperature. However, it is known that the external environment temperature generally does not change significantly within a preset time period. Therefore, it is necessary to further analyze and determine the DC charging information of the vehicle. For details, refer to Figure 5 The illustrated embodiment is described in detail.

[0095] Reference Figure 5 According to the correspondence between the vehicle VIN code and the DC charging information, the DC charging information of the vehicle is analyzed and determined to include:

[0096] Step S210, obtaining whether the vehicle with the corresponding VIN code has been DC charged by a charging pile in a preset area within a preset time period. If yes, executing step S220; if no, executing step S230.

[0100] Among them, the DC charging information performed by other vehicles of the same vehicle model as the vehicle with the current VIN code through charging piles in a preset area within a preset time period can be queried and obtained from a preset storage device that stores the DC charging information performed by other vehicles of the same vehicle model as the vehicle with the current VIN code through charging piles in a preset area within a preset time period.

If the information is found, step S223 is executed; otherwise, step S224 is executed.

[0104] Step S223, using the DC charging information under the corresponding outside temperature value obtained by query as the DC charging information of the vehicle with the corresponding VIN code this time.

[0108] Among them, the process of calculating the average DC charging information based on the DC charging information within the corresponding external temperature value range obtained from all queries is as follows: Since the DC charging information includes the DC charging voltage and the DC charging current, the average DC charging voltage and the average DC charging current will be calculated respectively, which will form the DC charging information of the vehicle with the corresponding VIN code.

[0109] Reference Figure 7 According to the DC charging information of other vehicles through the charging piles in the preset area within the preset time period, the DC charging information of the corresponding VIN code vehicle is predicted and analyzed, including:

[0110] Step S231, obtaining the DC charging information performed by the remaining vehicles through the charging piles in the preset area within the preset time period and the external temperature value of each charging period.

[0114] Among them, regarding the current outside temperature value as the median value and the preset temperature range, for example, assuming that the current outside temperature value is 20 degrees Celsius and the preset temperature range is 6 degrees Celsius, then the outside temperature value interval range is [17,23] degrees Celsius.

[0115] Step S235, calculating average DC charging information based on all the DC charging information in the corresponding ambient temperature range obtained through query, and using the average DC charging information as the DC charging information of the vehicle with the corresponding VIN code.

[0116] Among them, the process of calculating the average DC charging information based on the DC charging information within the corresponding external temperature value range obtained from all queries is as follows: Since the DC charging information includes the DC charging voltage and the DC charging current, the average DC charging voltage and the average DC charging current will be calculated respectively, which will form the DC charging information of the vehicle with the corresponding VIN code.

[0117] Reference Figure 8 , adjusting the DC charging information until the DC charging information obtained by the vehicle with the corresponding VIN code is consistent with the DC charging information of the vehicle determined by the analysis includes:

[0118] Step S610, obtaining a data source for analyzing the current DC charging information of the vehicle with the corresponding VIN code.

[0122] The process of redetermining the analyzed and determined vehicle DC charging information is as follows: first, analyze and determine the DC charging voltage difference and the DC charging current difference contained in the deviation information, then add the DC charging voltage difference to the existing DC charging voltage as the redetermined vehicle DC charging voltage, and add the DC charging current to the existing DC charging current as the redetermined vehicle DC charging current.

A DC charging method capable of automatically identifying a vehicle VIN code according to claim 1, characterized in that: According to the DC charging information of other vehicles through the charging piles in the preset area within the preset time period, the DC charging information of the vehicle with the corresponding VIN code is predicted and analyzed, including: Obtaining DC charging information performed by other vehicles through charging piles in a preset area within a preset time period and the outside temperature value of each charging period; According to the current outside temperature value, query and obtain the DC charging information under the corresponding outside temperature value from the DC charging information performed by the other vehicles through the charging piles in the preset area within the preset time period and the outside temperature value of each charging period; If found, the average DC charging information under the corresponding outside temperature value obtained by the query is used as the DC charging information of the vehicle with the corresponding VIN code; Anyway, the current outside temperature value is used as the median value and the preset temperature range to analyze and determine the current outside temperature value range, and the DC charging information performed by the vehicle with the corresponding VIN code through the charging pile in the preset area within the preset time period and the outside temperature value of each charging period is queried to obtain the DC charging information within the corresponding outside temperature value range; The average DC charging information is calculated based on the DC charging information in the corresponding outside temperature range obtained through all inquiries, and the average DC charging information is used as the DC charging information of the vehicle with the corresponding VIN code.

7. A DC charging system capable of automatically identifying a vehicle's VIN code, characterized in that: A DC charging method capable of automatically identifying a vehicle VIN code according to any one of claims 1 to 6, comprising: An identification module (1) is used to: identify and obtain a vehicle VIN code; An analysis and determination module (2) is used to: analyze and determine the DC charging information of the vehicle according to the corresponding relationship between the vehicle VIN code and the DC charging information; A sending module (3) is used to: send DC charging information to a charging pile for charging the vehicle; An acquisition module (4) is used to: acquire DC charging information acquired by a vehicle with a corresponding VIN code; A comparison module (5) is used to compare whether the DC charging information obtained by the vehicle with the corresponding VIN code is consistent with the sent DC charging information; The execution module (6) is used to: if the answer is no, adjust the DC charging information until the DC charging information obtained from the vehicle with the corresponding VIN code is consistent with the DC charging information of the vehicle determined by analysis; if the answer is yes, do not make any notification.
