DETAILED DESCRIPTION

[0036] Here, the exemplary embodiments will be described in detail, and examples are shown in the drawings.

[0037] In combination Figure 1 and Figure 2As shown, the embodiment of the present application provides a charging device 10, which comprises a charging device 11, a moving device 12 and a controller 13 electrically connected with the charging device 11 and the moving device 12.

[0038] The charging device 11 is used to connect with the charging port 210 of the vehicle 20 to be charged, and is controlled to charge the vehicle 20 to be charged. The charging device 11 is connected with the power supply through the power transmission line, so as to deliver the power of the power supply to the vehicle 20 to be charged in the case of connecting with the charging port 210 of the vehicle 20 to be charged, and realize the charging process of the vehicle 20 to be charged. The moving device 12 is connected with the charging device 11, and is used to move to drive the charging device 11 to move. The controller 13 is used to control the moving device 12 to move, so as to connect or disconnect the charging device 11 with the charging port 210 of the vehicle 20 to be charged. And the controller 13 is used to determine the charging mode of charging the vehicle 20 to be charged according to the charging information, and control the charging device 11 according to the charging mode. Wherein, the charging information comprises at least one of time information and quantity information of the vehicle 20 to be charged. The charging mode comprises a first mode and a second mode, and the charging power in the first mode is less than that in the second mode.

[0039] In the case of the current vehicle 20 to be charged, the controller 13 controls the moving device 12 to move, so as to drive the charging device 11 to connect with the charging port 210 of the vehicle 20 to be charged. The controller 13 determines the charging mode of charging the current vehicle 20 to be charged according to the charging information of the vehicle 20 to be charged, and the charging device 11 charges the vehicle 20 to be charged in the charging mode determined by the controller 13. In this way, in the process of automatic charging of the vehicle, the charging power of the charging process is determined according to at least one of the time information and the quantity information of the vehicle 20 to be charged in the actual application process, so as to realize the power control of the charging process, make the charging process better meet the actual charging demand of the vehicle, and be beneficial to improve the accuracy of the automatic charging process of the vehicle.

[0040] Here, the process that the controller 13 determines the charging mode of charging the vehicle 20 to be charged according to the charging information, and controls the charging device 11 according to the charging mode is further described.

[0041] In some embodiments, the charging information includes time information, and the time information includes a current time. The controller 13 is configured to determine that the charging mode for charging the vehicle 20 to be charged is the first mode if the current time belongs to the downtime, and control the charging device 11 according to the first mode. The controller 13 is configured to determine that the charging mode for charging the vehicle 20 to be charged is the second mode if the current time does not belong to the downtime, and control the charging device 11 according to the second mode. Vehicles in practical applications, especially public passenger vehicles, often have fixed use times, and correspondingly, there are generally fixed downtimes when the vehicles will not be used. For example, for a public passenger vehicle, the downtime is after the last stop time of the day and before the first stop time of the next day. Whether the current time belongs to the downtime can accurately determine whether the vehicle has an urgent use demand, thereby further determining the charging demand. If the current time belongs to the downtime, it is considered that the vehicle has a small possibility of use demand in a short time, and the first mode with a small charging power is used for charging at this time to avoid the adverse effects of fast charging on the vehicle battery in the automatic charging process. If the current time does not belong to the downtime, it means that the vehicle has a large possibility of use demand in a short time, and the second mode with a high charging power is used for charging at this time, which can improve the charging efficiency, shorten the charging time, and reduce the risk of affecting normal use. In this way, the charging mode is determined according to the current time, which is beneficial to coordinate the use demand and battery protection, thereby optimizing the user experience.

[0042] In some embodiments, the charging information includes time information, and the time information includes a current time and a preset use time. The controller 13 is configured to determine that the charging mode for charging the vehicle 20 to be charged is the first mode if a time interval between the current time and the predicted use time is greater than or equal to a time threshold, and control the charging device 11 according to the first mode. The controller 13 is configured to determine that the charging mode for charging the vehicle 20 to be charged is the second mode if the time interval between the current time and the predicted use time is less than the time threshold, and control the charging device 11 according to the second mode. In this way, the time available for charging can be accurately determined according to the current time and the predicted use time to further determine the appropriate charging mode corresponding to the time available for charging. If the time interval between the current time and the predicted use time is greater than or equal to the time threshold, it means that the time available for charging is sufficient, and the first mode with a small charging power is used for charging at this time, which can avoid the adverse effects of fast charging on the vehicle battery on the basis of meeting the vehicle power demand. If the time interval between the current time and the predicted use time is less than the time threshold, it means that the time available for charging is less, and the second mode with a high charging power is used for charging at this time, which can improve the charging efficiency to prioritize the power demand of the vehicle. In this way, the battery protection and the vehicle power demand can be considered.

[0043] The time length threshold value can be a preset fixed value, for example, one hour, two hours, etc., which is set according to the actual charging condition of the vehicle. In some embodiments, the time length threshold value can be calculated according to the remaining power of the vehicle to be charged 20. Specifically, the controller 13 obtains the remaining power and the target power of the vehicle to be charged 20, calculates the charging time required to charge to the target power according to the remaining power and the charging power of the first mode, and takes the charging time as the time length threshold value. Thus, determining the time length threshold value according to the actual power condition is beneficial to improve the accuracy of the time length threshold value, and further improve the accuracy of the charging mode selection. Further, on the basis of calculating the charging time required to charge to the target power according to the remaining power and the charging power of the first mode, a compensation time length can be added to reserve time for the movement of the charging device 11 and the related judgment and control process of the controller 13, so as to further improve the accuracy of the time length threshold value.

[0044] In some embodiments, the charging information includes time information, and the time information includes the current time and the preset use time. The controller 13 is configured to determine that the charging mode for charging the vehicle to be charged 20 is the first mode when the current time belongs to the downtime, and the time interval between the current time and the predicted use time is greater than or equal to the time length threshold value, and control the charging device 11 according to the first mode. The controller 13 is configured to determine that the charging mode for charging the vehicle to be charged 20 is the second mode when the current time does not belong to the downtime, or the time interval between the current time and the predicted use time is less than the time length threshold value, and control the charging device 11 according to the second mode. Considering that when the current time does not belong to the downtime, even if the time interval between the current time and the predicted use time is greater than or equal to the time length threshold value, the actual charging demand may change due to emergency use or other vehicle charging demand, etc., thereby causing the determined charging mode to be inconsistent with the charging demand. Therefore, the charging mode is determined according to two conditions that whether the current time belongs to the downtime, and whether the time interval between the current time and the predicted use time is greater than or equal to the time length threshold value, which is beneficial to further improve the accuracy of the charging mode selection.

[0045] In some embodiments, the charging information includes the number information of the to-be-charged vehicles 20. In the case that the number of the to-be-charged vehicles 20 is one, the controller 13 determines that the charging mode for charging the to-be-charged vehicles 20 is the first mode, and controls the charging device 11 according to the first mode. In the case that the number of the to-be-charged vehicles 20 is more than one, the controller 13 determines that the charging mode for charging the to-be-charged vehicles 20 is the second mode, and controls the charging device 11 according to the second mode. Here, the charging mode determination process is performed in consideration of the case that there is more than one to-be-charged vehicle 20 at the same time in actual application. This avoids the case that the charging mode is selected only according to the demand of a single to-be-charged vehicle 20, which seriously affects the charging of other vehicles. Thus, the charging mode is determined according to the number information of the to-be-charged vehicles 20, which is beneficial to coordinating the power demand and battery protection of vehicles in the overall charging scene, and improves the accuracy of the charging mode.

[0046] Further, in some embodiments, the charging information includes the time information and the number information of the to-be-charged vehicles 20. In this case, the controller 13 determines the charging mode for charging the to-be-charged vehicles 20 according to the time information and the number information of the to-be-charged vehicles 20. The time information can more accurately reflect the charging demand of individual vehicles, and the number information of the to-be-charged vehicles 20 can more accurately reflect the charging demand in the overall scene. Combining the time information and the number information of the to-be-charged vehicles 20 to determine the charging mode is beneficial to improving the accuracy of the charging mode and optimizing the charging control.

[0047] Specifically, in some embodiments, the time information includes the current time. In the case that the current time belongs to the downtime and the number of the to-be-charged vehicles 20 is one, the controller 13 determines that the charging mode for charging the to-be-charged vehicles 20 is the first mode, and controls the charging device 11 according to the first mode. In the case that the current time does not belong to the downtime, or the number of the to-be-charged vehicles 20 is more than one, the controller 13 determines that the charging mode for charging the to-be-charged vehicles 20 is the second mode, and controls the charging device 11 according to the second mode. In some embodiments, the time information includes the current time and the predicted vehicle use time. In the case that the time interval between the current time and the predicted vehicle use time is greater than or equal to the time threshold and the number of the to-be-charged vehicles 20 is one, the controller 13 determines that the charging mode for charging the to-be-charged vehicles 20 is the first mode, and controls the charging device 11 according to the first mode. In the case that the time interval between the current time and the predicted vehicle use time is less than the time threshold, or the number of the to-be-charged vehicles 20 is more than one, the controller 13 determines that the charging mode for charging the to-be-charged vehicles 20 is the second mode, and controls the charging device 11 according to the second mode.

[0048] The controller 13, after receiving the instruction information indicating that the vehicle 20 to be charged needs to start charging, performs the aforementioned process of controlling the moving device 12 to move until the charging device 11 is connected with the charging port 210, and determines the charging mode for charging the vehicle 20 to be charged according to the charging information. In some embodiments, the controller 13 is connected with a button or the like input device, and the user directly inputs the instruction information through the button or the like input device. In some embodiments, the controller 13 automatically determines whether the vehicle 20 to be charged needs to start charging according to the position of the vehicle 20 to be charged. Specifically, in some embodiments, the controller 13 is configured to control the moving device 12 to move until the charging device 11 is connected with the charging port 210 when the vehicle 20 to be charged is parked at a set position. The vehicle parking condition at the set position is monitored, and if a vehicle is parked at the set position, it indicates that the vehicle 20 to be charged needs to start charging, and the instruction information indicating that the vehicle 20 to be charged needs to start charging is generated to perform the subsequent charging control. In this way, the charging process can be automatically started without manual operation of the user.

[0049] The controller 13, after receiving the instruction information indicating that the vehicle 20 to be charged needs to end charging, controls the moving device 12 to move until the charging device 11 is disconnected from the charging port 210. In some embodiments, the controller 13 is connected with a button or the like input device, and the user directly inputs the instruction information through the button or the like input device. In some embodiments, the controller 13 automatically determines whether the vehicle 20 to be charged needs to stop charging according to the power of the vehicle 20 to be charged. Specifically, in some embodiments, the controller 13 is configured to control the moving device 12 to move until the charging device 11 is disconnected from the charging port 210 when the power of the vehicle 20 to be charged reaches a set power value. The set power value can be any power value set by the user, or the maximum power value. In this way, the charging process can be automatically ended without manual operation of the user.

[0050] In some embodiments, the moving device 12 includes a base 121, a first moving member 122, a second moving member 123, and a third moving member 124. The base 121 is provided with a groove in a first direction, the first moving member 122 is slidingly arranged in the groove in the first direction, the second moving member 123 is slidingly connected with the first moving member 122 in a second direction, and the third moving member 124 is telescopically arranged in the second moving member 123 in a third direction. The charging device 11 is arranged at the end of the third moving member 124, and the controller 13 is electrically connected with the first moving member 122, the second moving member 123, and the third moving member 124. The first direction, the second direction, and the third direction are different from each other. In this way, the position of the charging device 11 can be accurately controlled by controlling the first moving member 122, the second moving member 123, and the third moving member 124, and the charging device 11 can be conveniently connected with the charging port 210 of the vehicle 20 to be charged.

[0051] In some embodiments, the first direction, the second direction and the third direction are perpendicular to each other. In this way, the position control of the mobile device can be accurately realized.

[0052] In some embodiments, the charging device 10 further comprises a positioning device. The positioning device is arranged on the charging device 11 and is electrically connected with the controller 13, and is configured to obtain the relative position between the charging port 210 and the charging device 11. The controller 13 is configured to control the mobile device 12 to move according to the relative position between the charging port 210 and the charging device 11, so as to connect or disconnect the charging device 11 and the charging port 210. In this way, the relative position relationship between the charging device 11 and the charging port 210 can be accurately determined by the positioning device, so as to ensure the accuracy of the position control of the charging device 11. Specifically, the positioning device comprises an image sensor, which is configured to obtain an image of the direction in which the charging port 210 is located, so as to determine the specific position of the charging port 210. On the basis of the positioning device comprising the image sensor, the positioning device further comprises at least one of a distance sensor and a pressure sensor, so as to further determine whether the charging device 11 and the charging port 210 are tightly connected on the basis of the position alignment between the charging port 210 and the charging device 11, so that the normal charging process can be performed. In the implementation process, the radar sensor, the laser sensor and the like can be used as the positioning device, so as to accurately determine the position of the charging port 210.

[0053] In combination with Figure 3 It is shown that the embodiments of the present application provide a charging system, which comprises the charging device 10 and the charging cover 200 described above. In combination with Figure 4 and Figure 5 It is shown that the charging cover 200 is movably arranged on the vehicle to be charged 20 through a first connecting mechanism, the first connecting mechanism is electrically connected with the controller 13 of the charging device 10, and is controlled to drive the charging cover 200 to move to the first position to cover the charging port 210, or is controlled to drive the charging cover 200 to move to the second position to expose the charging port 210. In this way, the linkage control between the vehicle to be charged 20 and the charging device 10 can be realized in the case that the vehicle needs to be charged, and the fully automatic vehicle charging can be realized.

[0054] The process of controlling the first connecting structure to drive the charging cover 200 to move to the second position is provided with the same starting condition as the process of controlling the mobile device 12 to move until the charging device 11 is connected with the charging port 210. In this way, the synchronization of the linkage control between the charging device 10 and the vehicle to be charged 20 can be ensured. Specifically, in some embodiments, the controller 13 is configured to control the first connecting mechanism to drive the charging cover 200 to move to the second position when the vehicle to be charged 20 is parked at a set position. That is, the charging cover 200 is opened to expose the charging port 210.

[0055] Similarly, the process of controlling the first connecting mechanism to move the charging cover 200 to the first position is set with the same starting condition as the process of controlling the moving device 12 to move until the charging device 11 is disconnected from the charging port 210 to condense, to ensure the synchronization of the linkage control between the charging equipment 10 and the vehicle 20 to be charged. Specifically, in some embodiments, the controller 13 is configured to control the first connecting mechanism to move the charging cover 200 to the first position when the charging device 11 is disconnected from the charging port 210. That is, the charging cover 200 is closed.

[0056] In some embodiments, the first connecting mechanism includes a first connecting piece arranged on the charging cover 200 and a first matching piece arranged on the vehicle 20 to be charged, and the first connecting piece is in sliding connection with the first matching piece. The first connecting piece is electrically connected with the controller 13, and is configured to be controlled to move relative to the first matching piece to drive the charging cover 200 to move. Compared with the common flip cover design of the charging cover 200, the first connecting piece in sliding connection is used to connect the charging cover 200 and the vehicle 20 to be charged in this embodiment, which can better ensure the accuracy of control when the charging cover 200 is automatically opened, so that the charging port 210 is fully exposed, and the situation that the charging cover 200 partially blocks the charging port 210 or the charging cover 200 blocks the moving path of the charging device 11 does not occur.

[0057] Specifically, in combination with the embodiments shown in Figure 4 , Figure 5 and Figure 6 , in some embodiments, the first connecting piece includes a sliding rail 201, a gear 202 and a motor 203. The sliding rail 201 is fixed to the charging cover 200. The gear 202 is connected with the sliding rail 201 through a transmission mechanism. The motor 203 is connected with the gear 202, and the motor 203 is electrically connected with the controller 13. The motor 203 is configured to drive the gear 202 to rotate under control, and the gear 202 drives the sliding rail 201 to move through the transmission mechanism to drive the charging cover 200 to move. The first matching piece includes a sliding groove matched with the sliding rail 201, and the sliding groove is arranged on the vehicle 20 to be charged. In this way, the sliding control of the charging cover 200 can be realized.

[0058] In some embodiments, the sliding groove is arranged on the inner side of the vehicle 20 to be charged, which is close to the inner space of the vehicle compared with the outside environment. Correspondingly, the sliding rail 201 in the first connecting piece is arranged on the outer side of the charging cover 200, which is away from the inner space of the vehicle compared with the outside environment. That is, when the first connecting mechanism is controlled to move the charging cover 200 to the second position, at least part of the charging cover 200 is located on the inner side of the inner side of the vehicle 20 to be charged, which is close to the inner space of the vehicle compared with the outside environment.

[0059] In some embodiments, the vehicle 20 to be charged further includes a seal 204. The seal 204 is disposed on the charging cover 200, and when the charging cover 200 is in the closed state, the seal 204 is disposed along the circumferential direction of the charging cover 200 at its edge. When the charging cover 200 is in a first position, the seal 204 is disposed between the charging cover 200 and the body of the vehicle 20 to seal any gaps that may exist between the vehicle 20 to be charged and the charging cover 200, preventing dust or water and other impurities from entering the charging port 210.

[0060] In some embodiments, the vehicle 20 to be charged further includes a charging port cover 211. The charging port cover 211 is movably disposed between the charging port 210 and the charging cover 200 via a second connecting mechanism. The second connecting mechanism is electrically connected to the controller 13 and is controlled to move the charging port cover 211 to a third position to cover the charging port 210, or controlled to move the charging port cover 211 to a fourth position to expose the charging port 210. In the case where the vehicle 20 to be charged also includes a charging port cover 211, in some embodiments, the controller 13 is used to, when the vehicle 20 to be charged is parked in a set position, such as... Figure 4 As shown, the controller 13 controls the first connecting mechanism to move the charging cover 200 to the second position and controls the second connecting mechanism to move the charging port cover 211 to the fourth position. In some embodiments, the controller 13 is used to, when the charging device 11 is disconnected from the charging port 210, as follows: Figure 5 As shown, the first connecting mechanism is controlled to move the charging cover 200 to the first position, and the second connecting mechanism is controlled to move the charging port cover 211 to the third position. This effectively isolates the charging port 210 from the external environment of the vehicle 20 being charged by both the charging cover 200 and the charging port cover 211, further preventing dust, water, and other impurities from entering the charging port 210. The charging port cover 211 and the charging cover 200 open and close synchronously; that is, during charging, if the charging cover 200 needs to be opened, the charging port cover 211 is also controlled to open; if the charging cover 200 needs to be closed, the charging port cover 211 is also controlled to close. It should be noted that the synchronization here refers to the consistency of the switching states, and does not mean that the switching processes of the two are completely synchronized in time and distance.

[0061] In some embodiments, the vehicle 20 to be charged is further provided with a positioning and cooperating device that cooperates with the positioning device on the charging equipment 10. The positioning and cooperating device is electrically connected to the controller 13. The controller determines the docking relationship between the charging cover 200 and the charging port 210 of the vehicle 20 to be charged based on the positioning device and the positioning and cooperating device.

[0062] Combination Figure 7 As shown in the figure, this application discloses a charging control method applied to the aforementioned charging device. The charging control method includes steps S101 and S102.

[0063] In step S101, charging information is acquired; the charging information includes at least one of time information and quantity information of the to-be-charged vehicles.

[0064] In step S102, a charging mode for charging the to-be-charged vehicles is determined according to the charging information; the charging mode includes a first mode and a second mode, and the charging power in the first mode is less than the charging power in the second mode. The charging mode for charging the to-be-charged vehicles is determined according to the charging information, that is, the charging mode in which the charging device needs to operate when connected to the charging port of the to-be-charged vehicle is determined.

[0065] By using the charging control method provided in the embodiments of the present application, the charging power of the charging process is determined according to at least one of the time information and the quantity information of the to-be-charged vehicles in the actual application process during the automatic charging of the vehicle, the power control of the charging process is realized, the charging process is better adapted to the actual charging demand of the vehicle, and the accuracy of the automatic charging process of the vehicle is improved.

[0066] In some embodiments, the time information includes a current time. According to the charging information, the charging mode for charging the to-be-charged vehicles is determined, including: in a case where the current time belongs to a downtime, the charging mode is determined as the first mode; and in a case where the current time does not belong to the downtime, the charging mode is determined as the second mode. According to whether the current time belongs to the downtime, it can be more accurately judged whether the vehicle has an urgent demand for use, so as to further judge the charging demand thereof. If the current time belongs to the downtime, it is considered that the current vehicle has a smaller possibility of having a demand for use in a short time, and the first mode with a smaller charging power is used for charging at this time, so as to avoid the adverse effects of fast charging on the vehicle battery in the automatic charging process; if the current time does not belong to the downtime, it is considered that the current vehicle has a larger possibility of having a demand for use in a short time, and the second mode with a higher charging power is used for charging at this time, so as to improve the charging efficiency, shorten the charging time, and reduce the risk of affecting normal use. In this way, the charging mode is determined by the current time, which is beneficial to the coordination between the demand for use and the protection of the battery, so as to optimize the user experience.

[0067] In some embodiments, the time information comprises a current time and a predicted use time of the vehicle to be charged. According to the charging information, the charging mode for charging the vehicle to be charged is determined, including: in a case where a time interval between the current time and the predicted use time is greater than or equal to a time length threshold, determining that the charging mode is a first mode; in a case where the time interval between the current time and the predicted use time is less than the time length threshold, determining that the charging mode is a second mode. In this way, the time length available for charging can be accurately determined according to the current time and the predicted use time, so as to further accurately determine the charging mode corresponding to the time length for charging. If the time interval between the current time and the predicted use time is greater than or equal to the time length threshold, it means that the time for charging is sufficient, and the first mode with smaller charging power is used for charging at this time, which can avoid the adverse effects of fast charging on the vehicle battery on the basis of meeting the power demand of the vehicle. If the time interval between the current time and the predicted use time is less than the time length threshold, it means that the time for charging is less, and the second mode with higher charging power is used for charging at this time, which can improve the charging efficiency to prioritize the power demand of the vehicle. In this way, the battery protection and the power demand of the vehicle can be considered.

[0068] In some embodiments, the time length threshold can be a fixed value set in advance, for example, one hour, two hours, etc., which is set according to the actual charging condition of the vehicle. In some embodiments, the time length threshold can be calculated according to the remaining power of the vehicle to be charged. Specifically, the controller obtains the remaining power and the target power of the vehicle to be charged, and calculates the charging time length required for charging to the target power according to the remaining power and the charging power of the first mode. The charging time length is used as the time length threshold. In this way, the accuracy of the time length threshold is improved according to the actual power condition, and the accuracy of the charging mode selection is further improved. Further, based on the calculation of the charging time length required for charging to the target power according to the remaining power and the charging power of the first mode, a compensation time length can be added to reserve time for the movement of the charging device and the related judgment and control process of the controller, so as to further improve the accuracy of the time length threshold.

[0069] In some embodiments, the time information comprises a current time and a predicted use time of the vehicle to be charged. According to the charging information, the charging mode for charging the vehicle to be charged is determined, comprising: in a case that the current time belongs to a downtime, and a time interval between the current time and the predicted use time is greater than or equal to a time threshold, determining that the charging mode is a first mode; in a case that the current time does not belong to the downtime, or the time interval between the current time and the predicted use time is less than the time threshold, determining that the charging mode is a second mode. Considering that when the current time does not belong to the downtime, even if the time interval between the current time and the predicted use time is greater than or equal to the time threshold, the actual charging demand at the current time may change due to emergency use or other vehicle charging demand, thereby causing the determined charging mode to be inconsistent with the charging demand. Therefore, the charging mode is determined according to two conditions that whether the current time belongs to the downtime and whether the time interval between the current time and the predicted use time is greater than or equal to the time threshold, which is beneficial to further improve the accuracy of the charging mode selection.

[0070] In some embodiments, according to the charging information, the charging mode for charging the vehicle to be charged is determined, comprising: in a case that the number of vehicles to be charged is one, determining that the charging mode is a first mode; in a case that the number of vehicles to be charged is greater than one, determining that the charging mode is a second mode. Here, considering that in actual application, there may be more than one vehicle to be charged at the same time, the charging mode determination process is performed. In order to avoid selecting the charging mode according to the demand of a single vehicle to be charged, which may seriously affect the charging of other vehicles. In this way, the charging mode is determined according to the number information of the vehicles to be charged, which is beneficial to coordinate the electricity demand and battery protection of vehicles in the charging scene, and improves the accuracy of the charging mode.

[0071] Further, in some embodiments, the charging information includes time information and quantity information of the vehicles to be charged, and the charging mode for charging the vehicles to be charged is determined according to the time information and the quantity information of the vehicles to be charged together. The time information can more accurately reflect the charging demand of the individual vehicle, and the quantity information of the vehicles to be charged can more accurately reflect the charging demand in the overall scenario. Determining the charging mode in combination with the time information and the quantity information of the vehicles to be charged can help improve the accuracy of the charging mode and optimize the charging control. Specifically, in some embodiments, the time information includes the current time. According to the charging information, the charging mode for charging the vehicles to be charged is determined, including: in the case that the current time belongs to the downtime and the quantity of the vehicles to be charged is one, determining that the charging mode for charging the vehicles to be charged is the first mode; in the case that the current time does not belong to the downtime or the quantity of the vehicles to be charged is more than one, determining that the charging mode for charging the vehicles to be charged is the second mode. In some embodiments, the time information includes the current time and the predicted vehicle use time. According to the charging information, the charging mode for charging the vehicles to be charged is determined, including: in the case that the time interval between the current time and the predicted vehicle use time is greater than or equal to the time threshold and the quantity of the vehicles to be charged is one, determining that the charging mode for charging the vehicles to be charged is the first mode; in the case that the time interval between the current time and the predicted vehicle use time is less than the time threshold or the quantity of the vehicles to be charged is more than one, determining that the charging mode for charging the vehicles to be charged is the second mode. In this way, the accuracy of the selected charging mode can be further improved.
