[0078] According to the comparison result between the maximum output voltage value of the charging pile and the insulation voltage value, the available charging voltage value of the charging station is determined, including:

[0079] When the maximum output voltage value of the charging pile is greater than the insulation voltage value, if during the charging process, the actual charging voltage value is greater than the specified preset value, the maximum output voltage value of the charging pile is used as the available charging voltage value of the charging station, otherwise the insulation voltage value is used as the available charging voltage value of the charging station; or,

[0080] When the maximum output voltage value of the charging pile is less than or equal to the insulation voltage value, the maximum output voltage value of the charging pile is used as the available charging voltage value of the charging site.

[0084] The following is further described in detail:

[0085] When a vehicle is charged through a charging pile, the vehicle's on-board system can monitor the charging process of the vehicle battery and record the corresponding charging parameter data. In this embodiment, the vehicle side obtains accurate information about the charging pile during charging by interacting with the charging pile. The charging event of the present application includes charging parameter information, and the charging parameter information includes at least one or more of the following information: charging time, brand logo of the charging pile, requested current per second, charging current per second, load current per second, charging voltage, etc. The vehicle's on-board system can also obtain map information of the charging event, and the map information may include the charging station corresponding to the charging pile and the location information corresponding to the charging station, wherein the location information corresponding to the charging station includes the location information of the charging pile (such as longitude and latitude, etc.).

[0086] In this embodiment, the vehicle side obtains accurate information of the charging pile by exchanging information with the charging pile. The charging mode can be divided into an AC charging mode and a DC charging mode.

[0087] In one embodiment, the charging mode is an AC charging mode.

[0088] After the user inserts the charging gun, the vehicle charging system will identify the CP (control pilot function) duty cycle output by the charging pile and the CC (connection confirm) resistance on the charging gun to limit the charging current. The charging current limit is set to I lmt , I lmt =M in {The current limit value corresponding to CC, the current limit value corresponding to CP}. Among them, CP is the handshake signal between the electric vehicle and the charging pile. The CP signal can change with the interaction state between the charging pile and the electric vehicle, and can reflect the current state of the charging pile.

[0089] During the entire charging process, the vehicle can determine the AC charging voltage value of the charging station based on the actual charging voltage usage range, that is, determine whether the charging voltage of the charging pile is 220V or 380V.

[0090] The available charging current value of a charging station can be determined according to the following logic:

[0091] Determine the charging current limit I lmt The comparison result is compared with the maximum AC charging current value Iac of the whole vehicle, and different processing methods are determined according to the comparison result.

[0092] in I lmt <The maximum AC charging current value of the vehicle Iac, if during the entire charging process, the output current reaches the first preset value within the first preset time, for example, there is a certain time T1, the output current reaches I lmt -ΔI, the charging current limit is used as the available charging current value of the charging station, that is, the available charging current value of the current charging station is marked as I lmt , otherwise the actual maximum charging current value in this charging process is used as the available charging current value of the current charging station; wherein ΔI can take an empirical value, which is not limited in this application; it should be noted that when I lmt =Iac, it can also be processed in this way.

[0093] in I lmt >The maximum AC charging current value of the vehicle I ac When the output current is the second preset value within the second preset time during the charging process, for example, if the output current is the second preset value within a certain time T2, ac output, the charging current limit is used as the available charging current value of the charging station, that is, the charging current I of the current charging station is changed to I lmt , otherwise the actual maximum charging current is used as the available charging current value of the current charging station.

[0094] In one embodiment, the charging mode is a direct current charging mode.

[0095] After the user inserts the charging gun, the charging pile can first send the insulation voltage value U to the vehicle end in sequence according to the national standard charging process. ins 、The maximum output voltage value of the charging pile is U max , the maximum output current value of the charging pile I max After the vehicle recognizes this information, it sends a request for voltage, current and other parameters, and waits for the vehicle and pile parameters to match successfully before officially starting charging.

[0096] During the entire charging process, the vehicle determines the available charging voltage and current values ​​of the charging station according to the following logic, including:

[0097] Wherein, determining the DC available charging voltage value includes:

[0098] Comparative insulation voltage value U ins And the maximum output voltage value of the charging pile U max .

[0099] When U max >U ins When the actual charging voltage value U is greater than the preset value during charging, for example, U>U ins + floating threshold, the maximum output voltage value of the charging pile is used as the available charging voltage value of the charging station, that is, the available charging voltage value of the current charging station is considered to be U max Otherwise, the insulation voltage value is taken as the available charging voltage value of the charging station, that is, the available charging voltage value is considered to be U ins ; Among them, the floating threshold can be an empirical value, which is not limited in this application;

[0100] When U max ins When the maximum output voltage of the charging pile is used as the available charging voltage value of the charging station, the maximum allowable charging voltage value of the charging station U max As the available charging voltage value of the current charging station. It should be noted that when U max =U ins It can also be handled in this way.

[0101] Wherein, determining the DC available charging current value includes:

[0102] Compare the maximum output current value I of the charging pile max and the maximum DC charging current value of the vehicle I dc .

[0103] When the maximum output current value of the charging pile is I max >The maximum AC charging current value of the vehicle I dc When the current output value within the third preset time length during the charging process is the third preset value, for example, if the current output value is the third preset value within a certain time T3,​dc output, the maximum output current value of the charging pile is used as the available charging current value of the charging station, that is, the available charging current value of the current charging station is marked as I max Otherwise, the actual maximum charging current value in this charging process is used as the available charging current value of the charging site, that is, the actual maximum charging current value is used as the available charging current value of the current charging site;

[0104] When the maximum output current value of the charging pile is I max <The maximum AC charging current value of the vehicle I dc When the current output value within the fourth preset time length during the charging process is the fourth preset value, for example, if the current output value is the fourth preset value within a certain time T4, max -ΔI' output, the maximum output current value of the charging pile is used as the available charging current value of the charging station, that is, the available charging current value of the current charging station is marked as Imax Otherwise, the actual maximum charging current value in this charging process is used as the available charging current value of the charging station, that is, the actual maximum charging current value is used as the available charging current value of the current charging station. It should be noted that when I max =I dc It can also be handled in this way.

[0105] Step S102, obtaining map information of the charging event, where the map information of the charging event includes the charging station corresponding to the charging pile and the location information corresponding to the charging station.

[0106] After the charging event is generated, the map information of the charging event is further obtained, and the map information of the charging event includes the charging station corresponding to the charging pile and the location information corresponding to the charging station, so that the charging event and the map information of the charging event are associated.

[0107] Step S103, uploading the charging event and map information to the cloud server.

[0108] After the vehicle completes the collection of vehicle-pile matching information with the charging pile, it generates a charging event and uploads the charging event and map information to the cloud server.

[0109] For example, the vehicle uploads the charging event p to the cloud server. i , when the charging event p i Can include: Charging mode M i 、The maximum charging current limit I issued by the charging pile max_i (When AC charging, I lmt , when DC charging is I max ), the actual available charging voltage value U of the charging pile i , Available charging current value I i , combined with the current charging start T start_iWith end time T end_i , and the in-vehicle map provides the charging station name N i , location information oci .

[0110] When charging is completed, the vehicle will collect these charging event samples p i ={M i , I max_i , U i , I i , T start_i , T end_i , N i , l oci}Upload to the cloud server. Where i can be greater than or equal to 1.

[0111] Step S104, receiving charging station charging information generated by the cloud server based on charging events and map information uploaded by at least two vehicle terminals.

[0112] The cloud server will send these charging event samples to i The charging event dataset P of a charging station is integrated into a charging event dataset P = {p1, p2, ..., p N Based on the charging event data set of each charging station uploaded by at least two vehicle terminals, the cloud server analyzes the charging parameter information of the charging station, marks the actual charging parameter information of each charging station according to the analysis results, and thus obtains the charging station charging information of each charging station and sends it to the vehicle terminal.

[0113] The vehicle side receives charging station charging information generated by the cloud server based on charging events and map information uploaded by at least two vehicle sides.

[0114] Step S105, updating the charging station charging information in the vehicle-mounted map of the vehicle according to the charging station charging information.

[0115] After the vehicle receives the charging station information generated by the cloud server, it compares the received charging station information with the original charging station map information in the vehicle map. If the comparison results are different, the charging station information in the vehicle map of the vehicle is updated according to the charging station information. If the vehicle map does not include the charging station information, the charging station information is added to the vehicle map.

[0116] In one embodiment, after updating the on-board map according to the charging station charging information, it may also include: obtaining the vehicle information, generating the vehicle charging recommendation information according to the vehicle information and the charging station charging information; marking the vehicle charging recommendation information to the charging station element of the on-board map.

[0117] In this embodiment, the updated charging station charging information can be matched with the vehicle information to obtain the vehicle charging recommendation information of the vehicle information. Optionally, generating the vehicle charging recommendation information based on the vehicle information and the charging station charging information includes: obtaining the charging station charging information, matching the charging piles of the charging station charging information with the vehicle information, selecting the charging station with a high matching degree as the target charging station, and generating the vehicle charging recommendation information based on the target charging station.

[0118] It can be seen from this embodiment that the present application obtains the charging parameter information of the charging pile without relying on the third-party charging station supplier to upload information. The present application can generate a charging event through the charging parameter information interacted between the vehicle and the charging pile; obtain the map information of the charging event, and the map information of the charging event includes the charging station corresponding to the charging pile and the location information corresponding to the charging station; upload the charging event and the map information to the cloud, so that the cloud receives the charging event and the map information uploaded by at least two vehicle ends to generate the charging station charging information. After the vehicle receives the charging station charging information sent by the cloud server, the charging station charging information in the vehicle-mounted map of the vehicle end can be updated according to the charging station charging information. Through the above processing, the problem of vehicle-side adaptation is taken into account. The vehicle-mounted map includes relatively accurate charging station charging information, so that it can provide users with more accurate charging station charging information, meet the user's charging navigation needs, and thus improve the user's car charging experience.

[0119] Figure 2 It is a second flow chart of the charging station information updating method shown in the embodiment of the present application.

[0120] like Figure 2 As shown, the present application provides a charging station information update method, which is applied to a cloud server, and the method includes:

[0121] Step S201, receiving charging events and map information of charging events uploaded by at least two vehicle terminals, wherein the charging event is generated by the vehicle terminal based on charging parameter information interacting with the charging pile, and the map information of the charging event includes the charging station corresponding to the charging pile and the location information corresponding to the charging station.

[0122] The cloud server receives charging events and map information of the charging events uploaded by at least two vehicle terminals.

[0123] Charging event sample uploaded by the car side of the cloud server p i ={M i , I max_i , U i , I i , T start_i , T end_i , N i , l oci}. p i Can include: Charging mode Mi 、The maximum charging current limit I issued by the charging pile max_i (When AC charging, I lmt , when DC charging is I max ), the actual available charging voltage value U of the charging pile i , Available charging current value I i , combined with the current charging start T start_i With end time T end_i , and the in-vehicle map provides the charging station name N i , location information oci .

[0124] Step S202: Generate charging station charging information based on charging events and map information of charging events uploaded by at least two vehicle terminals.

[0125] Step S202 may include: obtaining charging events of the same charging station within a preset time period based on map information; determining the charging mode of the charging station according to the charging mode information in the charging events; classifying and counting the charging parameter information under different charging modes in the charging events; and generating charging information of the charging station according to the statistical results.

[0126] Among them, the charging parameter information under different charging modes in the charging event is classified and counted, including:

[0127] In different charging modes in a charging event, the charging stations are classified into voltage levels according to the available charging voltage values. When the voltage levels are the same, the charging stations are classified into current levels according to the available charging current values.

[0128] The distribution frequency of the voltage level or the current level is counted, and when the distribution frequency of the voltage level or the current level is greater than a preset threshold, it is determined to be a valid classification.

[0129] This is described in further detail below.

[0130] The cloud server uploads the charging event sample p i The charging event dataset P of a charging station is integrated into a charging event dataset P = {p1, p2, ..., p N Based on the charging event data set of each charging station uploaded by at least two vehicle terminals, the cloud server analyzes the charging parameter information of the charging station, and marks the actual charging parameter information of each charging station according to the analysis results, thereby obtaining the charging station charging information of each charging station.

[0131] The cloud server processing process includes:

[0132] 1) Based on the map information, obtain the charging events of the same charging station within a preset time period.

[0133] For example, after obtaining the charging event P corresponding to the charging station, all charging station events P' of each charging station within a preset time period are obtained.

[0134] 2) Determine the charging mode of the charging station according to the charging mode information in the charging event.

[0135] Charging mode labeling processing method: If it is known based on the charging mode information in the charging event that the charging station has both AC charging mode and DC charging mode, it is considered that this charging station has both AC and DC charging piles.

[0136] 3) Classify and count the charging parameter information under different charging modes in the charging event; generate charging station charging information based on the statistical results.

[0137] In different charging modes during a charging event, the charging stations are classified into voltage levels according to the available charging voltage values. When the voltage levels are the same, the charging stations are classified into current levels according to the available charging current values. The distribution frequency of the voltage level or current level is statistically analyzed, and a valid classification is determined when the distribution frequency of the voltage level or current level is greater than a preset threshold.

[0138] For example, the charging parameter labeling processing method includes: the AC charging mode and the DC charging mode can be first classified according to the available charging voltage level, and then subdivided according to the available current level when the voltage gear level is consistent.

[0139] In one embodiment, the standard for classifying charging power levels of charging stations may be as shown in Table 1 below but is not limited thereto.

[0140]

[0141] Table 1

[0142] Taking the four types of charging power A, B, C, and D in Table 1 as an example, when the statistical distribution frequency is greater than the preset threshold, a certain type is considered valid, that is, the charging station has charging piles of this power level. The preset threshold can be determined based on experience.

[0143] For categories C and D, where the actual charging current is lower than the upper limit of the charging pile, taking category C as an example, data cleaning and cluster analysis can be performed on the charging samples to subdivide the current levels such as C1, C2, etc.

[0144] Through continuous monitoring and analysis of big data, the actual charging power level type and distribution information of the charging station can be obtained, and finally the charging station charging information is generated. The power station charging information includes the actual power information of the charging station.

[0145] Step S203, sending the charging station charging information to the vehicle end, so that the vehicle end updates the charging station charging information in the vehicle map of the vehicle end according to the charging station charging information.

[0146] The cloud server sends the charging station information to the vehicle, and the vehicle can update the charging station information in the vehicle map based on the charging station information. In other words, the vehicle adds the charging function level type and distribution information of the charging stations collected by the cloud to the vehicle map, so that users can go to charging stations with high actual charging power and high frequency of high-power gear charging according to the updated or supplemented charging station information in the vehicle map, thereby improving the user's charging experience.

[0147] It can be found that in the embodiment of the present application, the vehicle end uploads charging events and map information of charging events to the cloud server, and the cloud server generates charging station charging information based on the charging events and map information of charging events uploaded by at least two vehicle ends; the charging station charging information is sent to the vehicle end, so that the vehicle end updates the charging station charging information in the vehicle map of the vehicle end according to the charging station charging information. Based on the big data analysis method, the cloud server calculates more accurate charging station charging information of the charging station, thereby providing the vehicle end with more accurate charging station charging information without relying on third-party information, meeting the user's charging navigation needs, and thus improving the user's car charging experience.

[0148] Figure 3 is a schematic diagram of the application system architecture of the charging station information update method shown in an embodiment of the present application; Figure 4 It is a third flow chart of the charging station information updating method shown in the embodiment of the present application.

[0149] The following is further combined Figure 3 and Figure 4 Describe the technical solution of this application.

[0150] like Figure 3 As shown, it is an application system architecture based on the vehicle-charging pile-cloud platform, which mainly includes charging piles, vehicles (including charging systems, on-board maps), and cloud servers (cloud platforms).

[0151] like Figure 4 As shown, Figure 4 The application environment includes: charging piles, vehicle terminals, and cloud servers.

[0152] Figure 4 The charging station information update method includes:

[0153] Step S1: The charging pile sends the maximum charging current / voltage value to the vehicle.

[0154] Step S2: The vehicle side identifies the maximum charging current / voltage value of the charging pile.

[0155] Step S3: Send a voltage / current request to the charging pile.

[0156] Step S4: The charging pile outputs voltage / current according to the request of the vehicle.

[0157] Step S5: The vehicle side calculates the actual available voltage / current of the charging pile based on the data of the charging pile.

[0158] Step S6: The vehicle uploads the charging event data to the cloud.

[0159] Step S7: The cloud server determines the charging station information based on the big data and sends the charging station information to the vehicle.

[0160] Step S8: The vehicle updates the charging station charging information on the onboard map.

[0161] It can be found that when the charging station has maintenance and upgrades or introduces new charging piles but the specific charging parameter information is not uploaded to the map, the vehicle side can capture the change information, and after analysis and processing by the cloud server, the charging information can be supplemented to the on-board map to provide users with more comprehensive charging information of the charging station; the present application can provide the actual power information of the vehicle going to the charging station to charge, so that users can make better choices based on the charging information of these charging stations, truly satisfying the user's supercharging experience.
