The embodiments described below with reference to the accompanying drawings are exemplary and are intended to explain the present application, and should not be construed as limiting the present application.

[0026] The charging method and device for a vehicle according to an embodiment of the present application will be described below with reference to the accompanying drawings. In view of the problem in the related art mentioned in the above background art that only the total number of charging piles in the charging station and the usage status of the charging piles can be dynamically displayed, resulting in the user being unable to select the best charging pile according to the charging requirements of the vehicle, the intelligent level is low, the charging time of the user is increased, the charging experience of the user is reduced, and the charging requirements of the user cannot be met, the present application provides a charging method for a vehicle. In this method, the target charging power of the vehicle to be charged can be received, and the available charging power of the idle charging guns of the charging devices can be obtained from the charging server, so as to match the target idle charging gun corresponding to each vehicle to be charged. According to the actual position of each vehicle to be charged and the actual position of the target idle charging gun, a charging path is generated, and then the vehicle to be charged is moved to the corresponding target idle charging gun for charging, effectively improving the intelligent level of the vehicle and the charging experience of the user. Thus, the problem in the related art that only the total number of charging piles in the charging station and the usage status of the charging piles can be dynamically displayed, resulting in the user being unable to select the best charging pile according to the charging requirements of the vehicle, the intelligent level is low, the charging experience of the user is reduced, and the charging requirements of the user cannot be met is solved.

[0027] Specifically, Figure 1Schematic flow chart of a charging method for a vehicle provided by an embodiment of the present application.

[0028] As Figure 1 shown, this charging method for the vehicle is applied to a server, and the method includes the following steps:

[0029] In step S101, receive the target charging power of at least one vehicle to be charged, and obtain the available charging power of at least one idle charging gun of at least one charging device from the charging server.

[0030] It can be understood that the server in the embodiment of the present application can receive the target charging power of at least one vehicle to be charged. For example, the server can receive the current battery level and the maximum required charging power uploaded by the vehicle, and can also obtain the available charging power of at least one idle charging gun of at least one charging device from the charging server, effectively improving the executability of intelligent charging of the vehicle.

[0031] In the embodiment of the present application, at least one charging device can be a charging pile in a charging station. The charging station can regularly upload the actual status of the charging pile and the charging gun, that is, whether there is a vehicle charging currently, the number of current idle charging guns, the SOC (state-of-charge) of the currently charging vehicle, and the estimated remaining charging time on the FCBUS (Fast charge bus), to the charging server to determine the maximum available charging power of the idle charging gun.

[0032] Among them, in an embodiment of the present application, the target charging power is the maximum required charging power of at least one vehicle to be charged, and the available charging power is the maximum available charging power of at least one idle charging gun.

[0033] In the actual execution process, the target charging power in the embodiment of the present application is the maximum required charging power of the vehicle to be charged, and the available charging power is the maximum available charging power of the idle charging gun. The embodiment of the present application can use the maximum required charging power and the available maximum charging power to determine the best idle charging gun in the charging pile, effectively improving the accuracy of vehicle charging.

[0034] In step S102, match the target idle charging gun corresponding to each vehicle to be charged according to the target charging power and the available charging power.

[0035] It can be understood that the server in the embodiment of the present application can match the target idle charging gun corresponding to each vehicle to be charged according to the target charging power and the available charging power in the following steps. Among them, the maximum charging power that the target idle charging gun can provide has the best matching result with the maximum power required by the vehicle to be charged, effectively improving the charging efficiency of the vehicle and saving charging time.

[0036] Among them, in an embodiment of the present application, matching the target idle charging gun corresponding to each vehicle to be charged according to the target charging power and the available charging power includes: obtaining the ambient temperature of the current environment where each vehicle to be charged is located; determining the target charging power according to the ambient temperature of the current environment, so as to match the target idle charging gun corresponding to each vehicle to be charged according to the target charging power and the available charging power.

[0037] In some embodiments, the server in the embodiment of the present application can obtain the ambient temperature of the current environment where the vehicle to be charged is located through an external vehicle sensor, determine the maximum charging power required by the vehicle to be charged according to the ambient temperature, so as to match the target idle charging gun corresponding to each vehicle to be charged according to the required maximum charging power and the available maximum charging power. Among them, since the ambient temperature of the current environment where the vehicle to be charged is located will affect the cell temperature of the battery and the target charging power. For example, when the ambient temperature of the current environment where the vehicle to be charged is located is relatively low, the charging efficiency of the battery will be reduced, etc. The embodiment of the present application can maximize the utilization of charging station resources by dynamically obtaining the SOC of the in-vehicle battery, and meet the charging needs of more users.

[0038] In step S103, a charging path is generated according to the actual positions of each vehicle to be charged and the actual position of the target idle charging gun, and each vehicle to be charged is controlled to move to the corresponding target idle charging gun along the charging path for charging.

[0039] It can be understood that the server in the embodiment of the present application can generate a charging path according to the actual positions of each vehicle to be charged and the actual position of the target idle charging gun. For example, the server can obtain the actual position of the vehicle to be charged and obtain the actual position of the target idle charging gun from the charging server, so as to generate a charging path, and then control the vehicle to be charged to move to the corresponding target idle charging gun along the charging path for charging. At the same time, the embodiment of the present application can also send the charging path to the user's mobile phone APP or the vehicle's central control screen. The user can drive the vehicle to the corresponding idle charging gun according to the navigation path on the central control screen for charging, effectively improving the interactivity of the vehicle and enhancing the user's charging experience.

[0040] Optionally, in an embodiment of the present application, after charging, it further includes: obtaining the charging status and remaining charging time of the corresponding target idle charging gun; presenting the charging status and remaining charging time to the user.

[0041] For example, the server in the embodiment of the present application can obtain the charging status of the idle charging gun in real time, such as the "in use or idle" status, and the user can view the charging status in real time through the mobile phone APP. To prevent the idle charging gun from being occupied by other vehicles to be charged during the process of the vehicle to be charged moving along the charging path to the idle charging gun, the user can plan a new charging path in advance, effectively improving the user's charging experience.

[0042] For another example, when the charging status of the idle charging gun is "in use", the server in the embodiment of the present application can obtain the remaining charging time of the idle charging gun. If the required time for the vehicle to be charged to move along the charging path to the idle charging gun is greater than the remaining charging time, then the idle charging gun can also be used as the best idle charging gun to charge the vehicle to be charged, effectively improving the charging efficiency of the vehicle.

[0043] Optionally, in an embodiment of the present application, during the process of moving to the corresponding target idle charging gun according to the charging path, it further includes: obtaining the available charging power of the new idle charging gun; judging whether the vehicle meets the preset replacement condition according to the available charging power of the new idle charging gun and the available charging power of the target idle charging gun; if it meets the preset replacement condition, then generating a new charging path based on the actual position of the new idle charging gun.

[0044] In the embodiment of the present application, the preset replacement condition is that the new idle charging gun is closer to the vehicle to be charged and the maximum available charging power is better than that of the target idle charging gun.

[0045] In the actual execution process, the server in the embodiment of the present application can obtain the available charging power of the new idle charging gun in real time, judge whether the vehicle meets the replacement condition according to the available charging power of the new idle charging gun and the available charging power of the target idle charging gun. When the replacement condition is met, a new charging path is generated based on the actual position of the new idle charging gun, and the vehicle to be charged is controlled to move to the new target idle charging gun along the new charging path for charging, effectively improving the charging efficiency of the vehicle and meeting the charging needs of the user.

[0046] In some embodiments, such as Figure 2As shown, in Link 1 of the embodiment of the present application, the vehicle can upload the current power of the vehicle and the maximum demand power E0 under the current SOC state to the vehicle cloud, that is, the server, through the T-box. In Link 2, the charging station can regularly upload the charging status of the charging pile and the charging gun, that is, whether there is a vehicle charging currently, the number of idle charging guns currently, the SOC of the currently charging vehicle, the estimated remaining charging time on the FCBUS, etc. to the pile cloud, that is, the charging server. The charging server obtains the maximum charging power that the idle charging gun can provide. For example, the maximum available power of the idle charging gun of a multi-output charging pile is:

[0047] P0 = P 总 -P 已用

[0048] Wherein, P0 is the available power value of the idle charging gun of the multi-output charging pile, P 总 is the maximum output power value of the multi-output charging pile, and P 已用 is the occupied power value of the multi-output charging pile.

[0049] At this time, the charging server transmits the maximum available power of the idle charging gun to the server through Link 3, and the server issues it to the vehicle to be charged of the user. The vehicle to be charged judges whether the maximum charging power that the nearby charging station can provide meets the maximum demand power E0 under the current SOC state.

[0050] Among them, the required charging power of the vehicle to be charged in the current SOC state is: E0 ∈ [0, P0], and the maximum required charging power of the vehicle to be charged in the current SOC state is:

[0051] E0 = U0 × I0

[0052] Wherein, E0 is the required charging power of the vehicle in the current SOC state, U0 is the total voltage of the power battery in the current SOC state, and I0 is the maximum allowable charging current judged by the BMS in the current SOC state.

[0053] In addition, the maximum allowable charging current I0 judged by the BMS in the current SOC state is I0 ∈ [0, E0 / U0], and the capacity to be supplemented by the power battery in the current SOC state is:

[0054] D 需 = f t (SOC x , SOC 起始 , D 标 )

[0055] Wherein, SOC x is the charging cut-off SOC value set by the user in the in-vehicle charging center, SOC 起始 is the starting SOC value of the user's vehicle charging, and D 标 is the standard capacity of the user's vehicle power battery.

[0056] Among them, the functional relationship for the power battery to supplement its capacity is consistent with the initial design of the BMS.

[0057] Next, the embodiment of the present application can output the estimated remaining charging time as:

[0058] △T = D 需 / I0

[0059] Among them, △T is the estimated remaining charging time for the user, and D 需 is the capacity that the power battery needs to supplement at the current SOC state.

[0060] Moreover, the embodiment of the present application can send the vehicle charging information to the user's mobile APP via link 4 to inform the user, such as "Charging at charging pile No. XX, gun No. XX in XX charging station takes less time, and it is estimated that the power replenishment can be completed in XX minutes", subject to the actual status of the charging pile.

[0061] In addition, as Figure 3 shown, the embodiment of the present application can also consider the influence of the ambient temperature of the environment where the vehicle to be charged is currently located on the cell temperature T0 and the required power. The embodiment of the present application can divide the charging map into 13 intervals according to the ambient temperature to form a charging map matrix. For example, [-20, -15), [-15, -10), [-10, -5), [-5, -0), [0, 5), [5, 10), [10, 15), [15, 20), [20, 25), [25, 30), [30, 35), [35, 40), [40, 45). Specifically, it can be detailedly distinguished according to the characteristics of different system cells, effectively improving the intelligent level of vehicle charging.

[0062] According to the vehicle charging method proposed by the embodiment of the present application, it can receive the target charging power of the vehicle to be charged, obtain the available charging power of the idle charging gun of the charging device from the charging server, thereby match the target idle charging gun corresponding to each vehicle to be charged, generate a charging path according to the actual position of each vehicle to be charged and the actual position of the target idle charging gun, and then move the vehicle to be charged to the corresponding target idle charging gun for charging, effectively improving the intelligent level of the vehicle and enhancing the user's charging experience. Thus, it solves the problem in the related art that only the total number of charging piles in the charging station and the usage status of the charging piles can be dynamically displayed, resulting in the user being unable to select the best charging pile according to the vehicle's charging needs, with a low intelligent level, reducing the user's charging experience, and being unable to meet the user's charging needs.

[0063] Next, describe the vehicle charging device proposed by the embodiment of the present application with reference to the accompanying drawings.

[0064] Figure 4It is a block diagram of a charging device for a vehicle according to an embodiment of the present application.

[0065] As Figure 4 shown, the charging device 10 of the vehicle includes: a receiving module 100, a matching module 200, and a control module 300.

[0066] Specifically, the receiving module 100 is configured to receive the target charging power of at least one vehicle to be charged, and obtain the available charging power of at least one idle charging gun of at least one charging device from a charging server.

[0067] The matching module 200 is configured to match the target idle charging gun corresponding to each vehicle to be charged according to the target charging power and the available charging power.

[0068] The control module 300 is configured to generate a charging path according to the actual position of each vehicle to be charged and the actual position of the target idle charging gun, and control each vehicle to be charged to move to the corresponding target idle charging gun according to the charging path for charging.

[0069] Optionally, in an embodiment of the present application, the target charging power is the maximum required charging power of at least one vehicle to be charged, and the available charging power is the maximum charging power that at least one idle charging gun can provide.

[0070] Optionally, in an embodiment of the present application, the matching module 200 includes: an obtaining unit and a matching unit.

[0071] Among them, the obtaining unit is configured to obtain the ambient temperature of the current environment where each vehicle to be charged is located.

[0072] The matching unit is configured to determine the target charging power according to the ambient temperature of the current environment, so as to match the target idle charging gun corresponding to each vehicle to be charged according to the target charging power and the available charging power.

[0073] Optionally, in an embodiment of the present application, the device 10 according to the embodiment of the present application further includes: a first obtaining module and a display module.

[0074] Among them, the first obtaining module is configured to obtain the charging status and the remaining charging time of the corresponding target idle charging gun after charging.

[0075] The display module is configured to display the charging status and the remaining charging time to the user after charging.

[0076] Optionally, in an embodiment of the present application, the device 10 according to the embodiment of the present application further includes: a second obtaining module, a judging module, and a processing module.

[0077] Among them, the second acquisition module is configured to acquire the available charging power of a new idle charging gun during the process of moving to the corresponding target idle charging gun along the charging path.

[0078] The judgment module is configured to judge whether the vehicle meets a preset replacement condition according to the available charging power of the new idle charging gun and the available charging power of the target idle charging gun during the process of moving to the corresponding target idle charging gun along the charging path.

[0079] The processing module is configured to generate a new charging path based on the actual position of the new idle charging gun during the process of moving to the corresponding target idle charging gun along the charging path if the preset replacement condition is met.

[0080] It should be noted that the foregoing explanation of the embodiments of the vehicle charging method also applies to the vehicle charging device in this embodiment, and will not be elaborated here.

[0081] The vehicle charging device provided according to the embodiments of the present application can receive the target charging power of the vehicle to be charged, and obtain the available charging power of the idle charging guns of the charging devices from the charging server, so as to match the target idle charging gun corresponding to each vehicle to be charged, generate a charging path according to the actual position of each vehicle to be charged and the actual position of the target idle charging gun, and then move the vehicle to be charged to the corresponding target idle charging gun for charging, effectively improving the intelligent level of the vehicle and the charging experience of users. Thus, it solves the problem in the related art that only the total number of charging piles in the charging station and the usage status of the charging piles can be dynamically displayed, resulting in users being unable to select the best charging pile according to the charging requirements of the vehicle, with a low intelligent level, reducing the charging experience of users, and being unable to meet the charging needs of users.
