BRIEF DESCRIPTION OF THE DRAWINGS

[0015] For ease of explanation, the present invention is described in detail with reference to the following specific embodiments and the accompanying drawings.

[0016] Figure 1 This is a flow chart of the present invention requesting a charging pile recommendation based on a charging APP; Figure 2 This is a flowchart of the present invention requesting charging pile recommendation based on the navigation system.

[0017] The technical solution in the real-time example of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the real-time example of the present invention.

[0018] Step 1: Charging pile power-on process.

[0019] After the charging pile is powered on, it first logs in and authenticates with the charging server (usually a charging platform provided by the charging operator), and reports the basic information of the charging pile, such as the charging pile code, charging pile type, rated output power of the charging pile, and number of charging pile guns, as well as the signature information, to the charging server. The charging server performs login verification on the charging pile based on the signature information, and feeds back the authentication result to the charging pile: success or failure. Charging pile types include DC piles and AC piles. A charging pile can have one or more charging guns.

[0020] This step previously described the power-on process of a charging pile. In actual implementation, the charging server will obtain the basic information of each charging pile through the power-on process of multiple charging piles.

[0021] Step 2: The charging pile periodically uploads real-time monitoring data.

[0022] In order for the charging server to understand the status of the charging pile and / or each charging gun in real time, the charging pile needs to monitor and upload the monitoring data to the charging server in real time. The real-time monitoring data includes the status of each charging gun, output voltage, gun line temperature and air temperature. For charging guns that are performing charging operations, real-time monitoring data is usually uploaded at intervals of 10 seconds; but for charging guns in an idle state, a longer time interval, such as 5 minutes, is used to upload real-time monitoring data.

[0023] This step previously described the power-on process of a charging pile. In actual implementation, the charging server will obtain the real-time monitoring data of each charging pile through periodic uploading of multiple charging piles.

[0024] Step 3: The user initiates a charging pile query through the charging client.

[0025] The user initiates a charging pile query through the charging client on the mobile phone or vehicle terminal. The query can be initiated by the user clicking the "query" function, or it can be initiated when the user's preset blood test conditions are met, such as the remaining power of the power battery is less than 30% of the rated capacity. The charging client is usually a charging application provided by the charging platform provider, that is, the charging APP on the mobile phone or vehicle terminal.

[0026] Furthermore, after receiving the charging pile query task, the charging client obtains the power battery information of the electric vehicle to be charged, including the power battery type, rated capacity, maximum charging power, supported pile type and remaining power. For example, the charging client pre-binds an electric vehicle and obtains the power battery type, rated capacity, maximum charging power, supported pile type and remaining power of the electric vehicle by accessing the BMS (Battery Management System) of the bound electric vehicle. We do not restrict the specific way in which the charging client obtains the power battery information of the electric vehicle to be charged.

[0027] Step 4: The charging client sends a charging pile information request to the charging server.

[0028] The charging client sends a request for charging pile information to the charging server. The request message contains power battery information such as power battery type, rated capacity, maximum charging power, supported pile types and remaining power. The request message may also contain target charging pile information to specify to the charging server which charging pile information is requested. The target charging pile information may specifically be geographic location or geographic area information to specify to the charging server which location or geographic area the charging pile information is requested. As an alternative, the target charging pile information may be the positioning information of the car to be charged, such as GPS or Beidou positioning information. At this time, the target charging pile is the charging pile closest to the location or all the charging piles in the charging station closest to the location.

[0029] Step 5: The charging server sends a charging pile information response to the charging client When the charging server receives the charging pile information request, it matches the charging pile and / or charging gun (abbreviated as "charging pile / gun") according to the power battery information in the request message, combined with the basic information of the target charging pile and real-time monitoring data that has been obtained, and generates a recommended list of charging piles / guns containing at least one charging pile or charging gun and the expected charging time of each charging pile / gun in the list.

[0030] As a possible implementation method, the matching of charging pile / gun includes the following operations: (1) Among the target charging piles, select the charging piles / guns that are in an idle state and are consistent with the pile type supported by the power battery of the electric vehicle to be charged as matching objects.

[0031] (2) Prioritize the use of charging piles / chargers with a rated output power greater than or equal to the maximum charging power supported by the power battery.

[0032] (3) Give priority to using charging piles / guns with output voltages that reach the rated output voltage (such as 220V or 380V) and low gun line temperatures. During peak hours of electricity consumption, the output voltage of the charging pile / gun may be lower than the rated output voltage. The specific output voltage is related to the local electricity consumption, such as residential electricity consumption, factory electricity consumption, and charging pile electricity consumption. The voltage in areas with insufficient power supply may be low, which will also cause the actual charging power to be slightly lower. The gun line temperature will also affect the charging efficiency. Usually, if the gun line temperature is too high, the charging pile will reduce the charging power, and the reduction value is related to the gun line temperature. If the gun line temperature exceeds a limit, it will even trigger the charging termination protection. If the temperature is very low, the battery needs to be heated during charging, which also affects the charging time.

[0033] A recommended list of charging piles / guns is generated based on the above matching process. For each charging pile / gun in the list, the expected charging time of each charging pile / gun can be calculated based on the output voltage of the charging pile / gun, the gun line temperature and the local temperature, combined with the rated capacity and remaining power of the power battery. The expected charging time can be the time for full charging, or it can be multiple expected charging times for charging to multiple values ​​such as 60%, 80% and 100% of the rated capacity of the power battery. We do not restrict how to calculate the expected charging time, which can be based on empirical formulas or artificial intelligence learning.

[0034] Furthermore, while generating a recommended list of charging piles / guns and the expected charging time of each charging pile / gun in the list, key factors affecting the charging time of each charging pile / gun in the list can also be given, such as the output voltage of the charging pile / gun being too low, the gun line temperature being too high, and the local temperature being too low.

[0035] Step 6: The charging client feeds back charging pile recommendation information to the user.

[0036] After receiving the charging pile information response message, the charging client provides the user with charging pile recommendation information through a display screen or voice broadcast, based on the recommended list of charging piles / guns and the expected charging time of each charging pile / gun in the list, for reference by the user.

[0037] Step 1: Charging pile power-on process.

[0038] After the charging pile is powered on, it first logs in and authenticates with the charging server (usually a charging platform provided by the charging operator), and reports the basic information of the charging pile, such as the charging pile code, charging pile type, rated output power of the charging pile, and number of charging pile guns, as well as the signature information, to the charging server. The charging server performs login verification on the charging pile based on the signature information, and feeds back the authentication result to the charging pile: success or failure. Charging pile types include DC piles and AC piles. A charging pile can have one or more charging guns.

[0039] This step previously described the power-on process of a charging pile. In actual implementation, the charging server will obtain the basic information of each charging pile through the power-on process of multiple charging piles.

[0040] Step 2: The charging pile periodically uploads real-time monitoring data.

[0041] In order for the charging server to understand the status of the charging pile and / or each charging gun in real time, the charging pile needs to monitor and upload the monitoring data to the charging server in real time. The real-time monitoring data includes the status of each charging gun, output voltage, gun line temperature and air temperature. For charging guns that are performing charging operations, real-time monitoring data is usually uploaded at intervals of 10 seconds; but for charging guns in an idle state, a longer time interval, such as 5 minutes, is used to upload real-time monitoring data.

[0042] This step previously described the power-on process of a charging pile. In actual implementation, the charging server will obtain the real-time monitoring data of each charging pile through periodic uploading of multiple charging piles.

[0043] Step 3: The user initiates a charging pile query through the navigation client.

[0044] The user initiates a query of charging piles through the navigation client on the mobile phone or vehicle terminal. The query can be initiated by the user clicking the "query" function, or it can be initiated when the blood test conditions preset by the user are met, such as the remaining power of the power battery is less than 30% of the rated capacity. The navigation client is usually a navigation application provided by the navigation service provider, that is, a navigation APP on the mobile phone or vehicle terminal, such as Baidu Navigation or AutoNavi Navigation APP.

[0045] Furthermore, after receiving the charging pile query task, the navigation client obtains the power battery information of the electric vehicle to be charged, including the power battery type, rated capacity, maximum charging power, supported pile type and remaining power. For example, the navigation client pre-binds an electric vehicle and obtains the power battery type, rated capacity, maximum charging power, supported pile type and remaining power of the electric vehicle by accessing the BMS (Battery Management System) of the bound electric vehicle. We do not restrict the specific way in which the navigation client obtains the power battery information of the electric vehicle to be charged.

[0046] Step 4: The navigation client sends a charging pile information query to the navigation server.

[0047] The navigation client sends a charging pile information query to the navigation server. The query message contains power battery information such as power battery type, rated capacity, maximum charging power, supported pile types and remaining power. The query message may also contain target charging pile information to specify to the navigation server which charging piles' relevant information to query. The target charging pile information may specifically be geographic location or geographic area information to specify to the charging server which location or geographic area to query the charging pile information. As an alternative, the target charging pile information may be the positioning information of the car to be charged, such as GPS or Beidou positioning information. At this time, the target charging pile is the charging pile closest to the location or all the charging piles in the charging station closest to the location.

[0048] Step 5: The navigation server sends a charging pile information request to the charging server.

[0049] The navigation server sends a request for charging pile information to the charging server. The request message contains power battery information such as power battery type, rated capacity, maximum charging power, supported pile types, and remaining power. The request message may also contain target charging pile information to specify which charging pile information is requested from the charging service. The target charging pile information may specifically be geographic location or geographic area information to specify to the charging server which location or geographic area the charging pile information is requested from. As an alternative, the target charging pile information may be the positioning information of the car to be charged, such as GPS or Beidou positioning information. At this time, the target charging pile is the charging pile closest to the location or all the charging piles in the charging station closest to the location.

[0050] Step 6: The charging server sends a charging pile information response to the navigation server When the charging server receives the charging pile information request, it matches the charging pile and / or charging gun (abbreviated as "charging pile / gun") according to the power battery information in the request message, combined with the basic information of the target charging pile and real-time monitoring data that has been obtained, and generates a recommended list of charging piles / guns containing at least one charging pile or charging gun and the expected charging time of each charging pile / gun in the list.

[0051] As a possible implementation method, the matching of charging pile / gun includes the following operations: (1) Among the target charging piles, select the charging piles / guns that are in an idle state and are consistent with the pile type supported by the power battery of the electric vehicle to be charged as matching objects.

[0052] (2) Prioritize the use of charging piles / chargers with a rated output power greater than or equal to the maximum charging power supported by the power battery.

[0053] (3) Give priority to using charging piles / guns with output voltages that reach the rated output voltage (such as 220V or 380V) and low gun line temperatures. During peak hours of electricity consumption, the output voltage of the charging pile / gun may be lower than the rated output voltage. The specific output voltage is related to the local electricity consumption, such as residential electricity consumption, factory electricity consumption, and charging pile electricity consumption. The voltage in areas with insufficient power supply may be low, which will also cause the actual charging power to be slightly lower. The gun line temperature will also affect the charging efficiency. Usually, if the gun line temperature is too high, the charging pile will reduce the charging power, and the reduction value is related to the gun line temperature. If the gun line temperature exceeds a limit, it will even trigger the charging termination protection. If the temperature is very low, the battery needs to be heated during charging, which also affects the charging time.

[0054] A recommended list of charging piles / guns is generated based on the above matching process. For each charging pile / gun in the list, the expected charging time of each charging pile / gun can be calculated based on the output voltage of the charging pile / gun, the gun line temperature and the local temperature, combined with the rated capacity and remaining power of the power battery. The expected charging time can be the time for full charging, or it can be multiple expected charging times for charging to multiple values ​​such as 60%, 80% and 100% of the rated capacity of the power battery. We do not restrict how to calculate the expected charging time, which can be based on empirical formulas or artificial intelligence learning.

[0055] Furthermore, while generating a recommended list of charging piles / guns and the expected charging time of each charging pile / gun in the list, key factors affecting the charging time of each charging pile / gun in the list can also be given, such as the output voltage of the charging pile / gun being too low, the gun line temperature being too high, and the local temperature being too low.

[0056] Step 7: The navigation server sends the charging pile information to the navigation client The charging pile information includes a recommended list of charging piles / guns and the expected charging time of each charging pile / gun in the list, as well as optional key factors that affect the charging time.

[0057] Step 6: The navigation client feeds back charging pile recommendation information to the user.

[0058] After the navigation client receives the charging pile information response message, it provides the user with charging pile recommendation information through a display screen or voice broadcast based on the recommended list of charging piles / guns and the expected charging time of each charging pile / gun in the list, as well as optional key factors affecting the charging time.
