[0002] The proportion of electric vehicles in today's urban traffic is increasing, and the charging process of electric vehicles has a great impact on the user experience. At present, the charging control of electric vehicles generally relies entirely on manpower, that is, the user or relevant staff manually connects the charging gun to the vehicle to be charged, and ends the charging process by manually disconnecting the charging gun from the vehicle to be charged. This method not only relies too much on manpower, but also has safety hazards caused by improper plugging and unplugging of the charging gun. The related technology provides a charging device that can automatically move the charging gun to a set position, which improves the degree of automation of the charging process to a certain extent.

DETAILED DESCRIPTION

[0036] Reference will now be made in detail to exemplary embodiments, examples of which are illustrated in the accompanying drawings.

[0037] Combination Figure 1 and Figure 2As shown, an embodiment of the present application provides a charging device 10 , including a charging device 11 , a mobile device 12 , and a controller 13 electrically connected to the charging device 11 and the mobile 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 to the power supply through the power transmission line, so that when connected to the charging port 210 of the vehicle 20 to be charged, the power of the power supply is transmitted to the vehicle 20 to be charged, so as to realize the charging process of the vehicle 20 to be charged. The mobile device 12 is connected to 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 movement of the mobile device 12 so that the charging device 11 is connected or disconnected with the charging port 210 of the vehicle 20 to be charged. And the controller 13 is used to determine the charging mode for charging the vehicle 20 to be charged according to the charging information, and control the charging device 11 according to the charging mode. Among them, the charging information includes at least one of time information and the number information of the vehicle 20 to be charged. 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.

[0039] In the case where there is a 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 whether the charging mode for charging the current vehicle 20 to be charged is the first mode or the second mode 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 vehicle charging, the charging power of the charging process is determined according to at least one of the time information in the actual application process and the number information of the vehicles 20 to be charged, so that the power control of the charging process can be realized, so that the charging process better meets the actual charging needs of the vehicle, which is conducive to improving the accuracy of the automatic vehicle charging process.

[0040] Here, the process in which the controller 13 determines the charging mode for 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 the current time. The controller 13 is used to determine that the charging mode for charging the vehicle 20 to be charged is the first mode when the current time belongs to the downtime, and control the charging device 11 according to the first mode. The controller 13 is used to determine that the charging mode for charging the vehicle 20 to be charged is the second mode when 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 a fixed usage time. Correspondingly, there is generally a fixed downtime during which the vehicle will not be used. For example, a public passenger vehicle has an outage time after the last arrival time of the day and before the first departure time of the next day. According to whether the current time belongs to the downtime, it can be more accurately judged whether the vehicle has an urgent need for use, thereby further judging its charging needs. If the current time is out of service, it is considered that the current vehicle is unlikely to be in demand in a short period of time. At this time, the first mode with a lower charging power is used for charging to avoid the adverse effects of fast charging on the vehicle battery during the automatic charging process; if the current time is not out of service, it means that the current vehicle is likely to be in demand in a short period of time. At this time, the second mode with a higher charging power is used for charging, which can improve charging efficiency, shorten charging time, and reduce the risk of affecting normal vehicle use. In this way, determining the charging mode according to the current time is conducive to achieving coordination between vehicle demand and battery protection, thereby optimizing user experience.

[0042] In some embodiments, the charging information includes time information, and the time information includes the current time and the preset vehicle use time. The controller 13 is used to determine that the charging mode for charging the vehicle 20 to be charged is the first mode when the time interval between the current time and the expected vehicle use time is greater than or equal to the time threshold, and control the charging device 11 according to the first mode. The controller 13 is used to determine that the charging mode for charging the vehicle 20 to be charged is the second mode when the time interval between the current time and the expected vehicle 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 expected vehicle use time, so as to further determine the appropriate charging mode corresponding to the time used for charging. If the time interval between the current time and the expected time of use is greater than or equal to the time threshold, it means that the time for charging is sufficient. At this time, the first mode with a lower charging power is used for charging, which can meet the power demand of the vehicle and avoid the adverse effects of fast charging on the vehicle battery. If the time interval between the current time and the expected time of use is less than the time threshold, it means that the time for charging is short. At this time, the second mode with a higher charging power is used for charging, which can improve the charging efficiency and give priority to meeting the power demand of the vehicle. In this way, it is beneficial to take into account both battery protection and vehicle power demand.

[0043] Among them, the duration threshold can be a pre-set fixed value, such as one hour, two hours, etc., which is set according to the actual charging situation of the vehicle. In some embodiments, the duration threshold can be calculated based on the remaining power of the current vehicle 20 to be charged. Specifically, the controller 13 obtains the remaining power and target power of the vehicle 20 to be charged, 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 uses the charging time as the duration threshold. Determining the duration threshold according to the actual power situation in this way is conducive to improving the accuracy of the duration threshold, and then improving the accuracy of the charging mode selection. Furthermore, 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 can be added to reserve time for the movement of the charging device 11 and the relevant judgment and control process of the controller 13, so as to further improve the accuracy of the duration threshold.

[0044] In some embodiments, the charging information includes time information, and the time information includes the current time and the preset vehicle use time. The controller 13 is used to determine that the charging mode for charging the vehicle 20 to be charged is the first mode when the current time belongs to the outage time and the time interval between the current time and the expected vehicle use time is greater than or equal to the time threshold, and control the charging device 11 according to the first mode. The controller 13 is used to determine that the charging mode for charging the vehicle 20 to be charged is the second mode when the current time does not belong to the outage time or the time interval between the current time and the expected vehicle use time is less than the time threshold, and control the charging device 11 according to the second mode. Considering that when the current time does not belong to the outage time, even if the time interval between the current time and the expected vehicle use time is greater than or equal to the time threshold, it is possible that the current actual charging demand changes due to emergency use of the vehicle or other vehicle demand charging, thereby causing the determined charging mode to be inconsistent with the charging demand. Therefore, determining the charging mode based on the two conditions of whether the current time belongs to the outage time and whether the time interval between the current time and the expected vehicle use time is greater than or equal to the time threshold is conducive to further improving the accuracy of the charging mode selection.

[0045] In some embodiments, when the charging information includes the number information of the vehicles 20 to be charged, the controller 13 is used to determine that the charging mode for charging the vehicle 20 to be charged is the first mode when the number of the vehicles 20 to be charged is one, and control the charging device 11 according to the first mode. The controller 13 is used to determine that the charging mode for charging the vehicle 20 to be charged is the second mode when the number of the vehicles 20 to be charged is multiple, and control the charging device 11 according to the second mode. Here, considering that in actual applications, there may be more than one vehicle 20 to be charged at the same time, the charging mode determination process is performed. This is to avoid the situation where the charging mode is selected only according to the needs of a single vehicle 20 to be charged, which seriously affects the charging of other vehicles. In this way, determining the charging mode according to the number information of the vehicles 20 to be charged is conducive to coordinating the power demand and battery protection of the vehicle in the overall charging scenario, and improving the accuracy of the charging mode.

[0046] Furthermore, in some embodiments, the charging information includes time information and the number information of the vehicles 20 to be charged. At this time, the controller 13 determines the charging mode for charging the vehicles 20 to be charged based on the time information and the number information of the vehicles 20 to be charged. The time information can more accurately reflect the charging needs of individual vehicles, while the number information of the vehicles 20 to be charged can more accurately reflect the charging needs in the overall scenario. Combining the time information and the number information of the vehicles 20 to be charged to jointly determine the charging mode is conducive 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. The controller 13 is used to determine that the charging mode for charging the vehicle 20 to be charged is the first mode when the current time belongs to the outage time and the number of the vehicle 20 to be charged is one, and control the charging device 11 according to the first mode. The controller 13 is used to determine that the charging mode for charging the vehicle 20 to be charged is the second mode when the current time does not belong to the outage time or the number of the vehicle 20 to be charged is multiple, and control the charging device 11 according to the second mode. In some embodiments, the time information includes the current time and the expected vehicle use time. The controller 13 is used to determine that the charging mode for charging the vehicle 20 to be charged is the first mode when the time interval between the current time and the expected vehicle use time is greater than or equal to the time length threshold and the number of the vehicle 20 to be charged is one, and control the charging device 11 according to the first mode. The controller 13 is used to determine that the charging mode for charging the vehicle 20 to be charged is the second mode when the time interval between the current time and the expected vehicle use time is less than the time length threshold or the number of the vehicle 20 to be charged is greater than one, and control the charging device 11 according to the second mode.

[0048] After receiving the instruction information indicating that the vehicle 20 to be charged needs to start charging, the controller 13 executes the aforementioned process of controlling the mobile device 12 to move until the charging device 11 is connected to 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 to an input device such as a key, and the user directly inputs the instruction information through an input device such as a key. In some embodiments, the controller 13 automatically determines according to the position of the vehicle 20 to be charged to determine that the vehicle 20 to be charged needs to start charging. Specifically, in some embodiments, the controller 13 is used to control the mobile device 12 to move until the charging device 11 is connected to the charging port 210 when the vehicle 20 to be charged is parked at a set position. The parking situation of the vehicle at the set position is monitored. If a vehicle is parked at the set position, it means that the vehicle 20 to be charged needs to start charging. At this time, an instruction information indicating that the vehicle 20 to be charged needs to start charging is generated for subsequent charging control. In this way, the charging process starts automatically without manual operation by the user.

[0049] After receiving the instruction information indicating that the vehicle 20 to be charged needs to end charging, the controller 13 controls the mobile device 12 to move until the charging device 11 is disconnected from the charging port 210. In some embodiments, the controller 13 is connected to an input device such as a button, and the user directly inputs the instruction information through an input device such as a button. In some embodiments, the controller 13 automatically determines based on the power of the vehicle 20 to be charged to determine whether the vehicle 20 to be charged needs to stop charging. Specifically, in some embodiments, the controller 13 is used to control the mobile 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 here can be any power value set by the user, or it can be the maximum power value. In this way, the charging process can be automatically ended without manual operation by the user.

[0050] In some embodiments, the mobile device 12 includes a base 121, a first moving member 122, a second moving member 123 and a third moving member 124. Among them, the base 121 is provided with a groove along the first direction, the first moving member 122 is slidably arranged in the groove along the first direction, the second moving member 123 is slidably connected to the first moving member 122 along the second direction, and the third moving member 124 is telescopically arranged on the second moving member 123 along the third direction. The charging device 11 is arranged at the end of the third moving member 124, and the controller 13 is electrically connected to 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 here are different. In this way, the accurate control of the position of the charging device 11 can be achieved by controlling the first moving member 122, the second moving member 123 and the third moving member 124, so as to facilitate the connection of the charging device 11 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, so as to facilitate accurate position control of the mobile device.

[0052] In some embodiments, the charging device 10 further includes a positioning device. The positioning device is provided on the charging device 11 and is electrically connected to the controller 13, and is used to obtain the relative position of the charging port 210 and the charging device 11. The controller 13 is used to control the movement of the mobile device 12 according to the relative position of the charging port 210 and the charging device 11, so that the charging device 11 is connected or disconnected with 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, thereby ensuring the accuracy of the position control of the charging device 11. Specifically, the positioning device includes an image sensor to obtain an image in the direction of the charging port 210 to determine the specific position of the charging port 210. On the basis that the positioning device includes an image sensor, the positioning device also includes at least one of a distance sensor and a pressure sensor, so as to further determine whether the charging device 11 is closely connected with the charging port 210 on the basis of the alignment of the charging port 210 and the charging device 11, so that a normal charging process can be carried out. In the implementation process, a radar sensor, a laser sensor, etc. can be used as a positioning device to accurately determine the position of the charging port 210.

[0053] Combination Figure 3 As shown, the embodiment of the present application provides a charging system, including the aforementioned charging device 10 and a charging cover 200. Figure 4 and Figure 5 As shown, the charging cover 200 is movably arranged on the vehicle 20 to be charged through a first connection mechanism, and the first connection mechanism is electrically connected to the controller 13 of the charging device 10, and is controlled to drive the charging cover 200 to move to a first position to cover the charging port 210, or is controlled to drive the charging cover 200 to move to a second position to expose the charging port 210. In this way, when the vehicle needs to be charged, linkage control between the vehicle 20 to be charged and the charging device 10 can be realized, and fully automated vehicle charging can be realized.

[0054] The process of controlling the first connection structure to drive the charging cover 200 to move to the second position sets the same starting condition as the aforementioned process of controlling the movement of the moving device 12 until the charging device 11 is connected to the charging port 210. In this way, it is helpful to ensure the synchronization of the linkage control between the charging device 10 and the vehicle 20 to be charged. Specifically, in some embodiments, the controller 13 is used to control the first connection mechanism to drive the charging cover 200 to move to the second position when the vehicle 20 to be charged is parked at a set position. That is, open the charging cover 200 to expose the charging port 210.

[0055] Similarly, the process of controlling the first connection mechanism to drive the charging cover 200 to move to the first position is set with the same starting conditions as the aforementioned process of controlling the movement of the mobile device 12 until the charging device 11 is disconnected from the charging port 210 to condense, so as to ensure the synchronization of the linkage control between the charging device 10 and the vehicle to be charged 20. Specifically, in some embodiments, the controller 13 is used to control the first connection mechanism to drive the charging cover 200 to move 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 mating piece provided on the vehicle 20 to be charged and a first connecting piece provided on the charging cover 200, and the first connecting piece is slidably connected to the first mating piece. The first connecting piece is electrically connected to the controller 13, and is used for being controlled to move relative to the first mating piece to drive the charging cover 200 to move. Compared with the flip cover design of the common charging cover 200, the charging cover 200 and the vehicle 20 to be charged are connected by a slidingly connected first connecting piece, which can better ensure the accuracy of control when automatically opening, 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 is avoided.

[0057] Specifically, combined Figure 4 , Figure 5 and Figure 6 As shown, in some embodiments, the first connecting member includes a slide rail 201, a gear 202 and a motor 203. Among them, the slide rail 201 is fixed to the charging cover 200. The gear 202 is connected to the slide rail 201 through a transmission mechanism. The motor 203 is connected to the gear 202, and the motor 203 is electrically connected to the controller 13. The motor 203 is used to drive the gear 202 to rotate in a controlled manner. The gear 202 drives the slide rail 201 to move through the transmission mechanism to drive the charging cover 200 to move. The first matching member includes a slide groove that matches the slide rail 201, and the slide groove is opened on the vehicle 20 to be charged. In this way, the sliding control of the charging cover 200 can be achieved.

[0058] In some embodiments, the slide groove is provided on the inner side of the vehicle 20 to be charged which is closer to the interior space than the external environment, and accordingly, the slide rail 201 in the first connecting member is provided on the outer side of the charging cover 200 which is farther from the interior space than the external environment. That is, when the first connecting mechanism is controlled to drive the charging cover 200 to move 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 closer to the interior space than the external environment.

[0059] In some embodiments, the vehicle to be charged 20 further includes a seal 204. The seal 204 is disposed on the charging cover 200. When the charging cover 200 is in a closed state, the seal 204 is disposed on the edge of the charging cover 200 along the circumference of the charging cover 200. When the charging cover 200 is in the first position, the seal 204 is disposed between the charging cover 200 and the body of the vehicle to be charged 20 to block a possible gap between the vehicle to be charged 20 and the charging cover 200, and prevent impurities such as dust or water 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 through a second connection mechanism. The second connection mechanism is electrically connected to the controller 13, and is controlled to drive the charging port cover 211 to move to a third position to cover the charging port 210, or is controlled to drive the charging port cover 211 to move to a fourth position to expose the charging port 210. When the vehicle 20 to be charged further includes a charging port cover 211, in some embodiments, the controller 13 is used to, when the vehicle 20 to be charged is parked at a set position, such as Figure 4 As shown, the first connection mechanism is controlled to drive the charging cover 200 to move to the second position and the second connection mechanism is controlled to drive the charging port cover 211 to move to the fourth position. In some embodiments, the controller 13 is used to disconnect the charging device 11 from the charging port 210, such as Figure 5 As shown, the first connecting mechanism is controlled to drive the charging cover 200 to move to the first position and the second connecting mechanism is controlled to drive the charging port cover 211 to move to the third position. It is equivalent to setting up the charging cover 200 and the charging port cover 211 to jointly isolate the charging port 210 from the external environment of the vehicle 20 to be charged to further prevent impurities such as dust and water from entering the charging port 210. The charging port cover 211 and the charging cover 200 are opened and closed synchronously, that is, during the charging process, when the charging cover 200 needs to be opened, the charging port cover 211 is also controlled to be opened; when the charging cover 200 needs to be controlled to be closed, the charging port cover 211 is also controlled to be closed. It should be noted that the synchronization mentioned here refers to the consistency of the switch state, and does not mean that the switching process of the two is completely synchronized in time and travel.

[0061] In some embodiments, the vehicle to be charged 20 is also provided with a positioning and matching device that matches the positioning device on the charging device 10. The positioning and matching 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 to be charged 20 based on the positioning device and the positioning and matching device.

[0062] Combination Figure 7 As shown, an embodiment of the present application discloses a charging control method, which is applied to the aforementioned charging device. The charging control method includes step S101 and step S102.

[0063] Step S101, acquiring charging information; the charging information includes at least one of time information and the number of vehicles to be charged.

[0064] Step S102, determining a charging mode for charging the vehicle to be charged 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. Determining a charging mode for charging the vehicle to be charged according to the charging information, that is, determining a charging mode that the charging device needs to operate when connected to the charging port of the vehicle to be charged.

[0065] By adopting the charging control method provided in the embodiment of the present application, during the process of automatic vehicle charging, the charging power of the charging process is determined according to at least one of the time information in the actual application process and the number information of the vehicles to be charged. This can achieve power control of the charging process, make the charging process better meet the actual charging needs of the vehicle, and help to improve the accuracy of the vehicle's automatic charging process.

[0066] In some embodiments, the time information includes the current time. According to the charging information, the charging mode for charging the vehicle to be charged is determined, including: when the current time belongs to the outage time, the charging mode is determined to be the first mode; when the current time does not belong to the outage time, the charging mode is determined to be the second mode. According to whether the current time belongs to the outage time, it can be more accurately judged whether the vehicle has an urgent need for the vehicle, and thus further judge its charging needs. If the current time belongs to the outage time, it is considered that the current vehicle is less likely to have a vehicle demand in a short time. At this time, the first mode with a lower charging power is used for charging to avoid the adverse effects of fast charging on the vehicle battery during the automatic charging process; if the current time does not belong to the outage time, it means that the current vehicle is more likely to have a vehicle demand in a short time. At this time, the second mode with a higher charging power is used for charging, which can improve the charging efficiency, shorten the charging time, and reduce the risk of affecting normal vehicle use. In this way, determining the charging mode by the current time is conducive to achieving coordination between vehicle demand and battery protection, thereby optimizing the user experience.

[0067] In some embodiments, the time information includes the current time and the expected time of use of the vehicle to be charged. According to the charging information, the charging mode for charging the vehicle to be charged is determined, including: when the time interval between the current time and the expected time of use is greater than or equal to the time threshold, the charging mode is determined to be the first mode; when the time interval between the current time and the expected time of use is less than the time threshold, the charging mode is determined to be the second mode. In this way, the time available for charging can be accurately determined according to the current time and the expected time of use, so as to further accurately determine the charging mode corresponding to the time used for charging. If the time interval between the current time and the expected time of use is greater than or equal to the time threshold, it means that the time for charging is sufficient. At this time, the first mode with a smaller charging power is used for charging, which can avoid the adverse effects of fast charging on the vehicle battery on the basis of meeting the vehicle's power demand; if the time interval between the current time and the expected time of use is less than the time threshold, it means that the time for charging is less. At this time, the second mode with a higher charging power is used for charging, which can improve the charging efficiency to give priority to meeting the vehicle's power demand. In this way, it is beneficial to take into account both battery protection and vehicle power demand.

[0068] Among them, the duration threshold can be a pre-set fixed value, such as one hour, two hours, etc., which is set according to the actual charging situation of the vehicle. In some embodiments, the duration threshold can be calculated based on the remaining power of the current vehicle to be charged. Specifically, the controller obtains the remaining power and target power of the vehicle to be charged, and calculates the charging time required to charge to the target power based on the remaining power and the charging power of the first mode. The charging time is used as the duration threshold. Determining the duration threshold based on the actual power situation in this way is conducive to improving the accuracy of the duration threshold, and then improving the accuracy of the charging mode selection. Furthermore, on the basis of calculating the charging time required to charge to the target power based on the remaining power and the charging power of the first mode, a compensation time can be added to reserve time for the movement of the charging device and the relevant judgment and control process of the controller, so as to further improve the accuracy of the duration threshold.

[0069] In some embodiments, the time information includes the current time and the expected time of use of the vehicle to be charged. According to the charging information, the charging mode for charging the vehicle to be charged is determined, including: when the current time belongs to the outage time, and the time interval between the current time and the expected time of use is greater than or equal to the time threshold, the charging mode is determined to be the first mode; when the current time does not belong to the outage time, or the time interval between the current time and the expected time of use is less than the time threshold, the charging mode is determined to be the second mode. Considering that when the current time does not belong to the outage time, even if the time interval between the current time and the expected time of use is greater than or equal to the time threshold, it is possible that the current actual charging demand changes due to emergency use of the vehicle or other vehicle charging needs, thereby causing the determined charging mode to be inconsistent with the charging demand. Therefore, determining the charging mode based on the two conditions of whether the current time belongs to the outage time and whether the time interval between the current time and the expected time of use is greater than or equal to the time threshold is conducive to further improving the accuracy of the charging mode selection.

[0070] In some embodiments, the charging mode for charging the vehicle to be charged is determined based on the charging information, including: when the number of vehicles to be charged is one, determining the charging mode to be the first mode; when the number of vehicles to be charged is greater than one, determining the charging mode to be the second mode. Here, the charging mode determination process is performed taking into account the situation that there may be more than one vehicle to be charged at the same time in actual applications. This is to avoid the situation where the charging mode is selected only based on the needs of a single vehicle to be charged, which seriously affects the charging of other vehicles. In this way, determining the charging mode based on the number information of the vehicles to be charged is conducive to coordinating the power demand and battery protection of the vehicle in the overall charging scenario, and improves the accuracy of the charging mode.

[0071] Further, in some embodiments, the charging information includes time information and information about the number of vehicles to be charged, and the charging mode for charging the vehicle to be charged is determined based on the time information and the number of vehicles to be charged. The time information can more accurately reflect the charging needs of individual vehicles, while the number of vehicles to be charged can more accurately reflect the charging needs in the overall scenario. Determining the charging mode in combination with the time information and the number of vehicles to be charged is conducive to improving the accuracy of the charging mode and optimizing 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 vehicle to be charged is determined, including: when the current time belongs to the downtime and the number of vehicles to be charged is one, the charging mode for charging the vehicle to be charged is determined to be the first mode; when the current time does not belong to the downtime, or the number of vehicles to be charged is multiple, the charging mode for charging the vehicle to be charged is determined to be the second mode. In some embodiments, the time information includes the current time and the expected vehicle use time. According to the charging information, the charging mode for charging the vehicle to be charged is determined, including: when the time interval between the current time and the expected vehicle use time is greater than or equal to the time threshold and the number of vehicles to be charged is one, the charging mode for charging the vehicle to be charged is determined to be the first mode; when the time interval between the current time and the expected vehicle use time is less than the time threshold, or the number of vehicles to be charged is greater than one, the charging mode for charging the vehicle to be charged is determined to be the second mode. In this way, the accuracy of the selected charging mode can be further improved.

If there is a vehicle parked at the set position, it is determined that there is instruction information indicating that the vehicle to be charged starts charging. Or, detect whether the user of the vehicle to be charged presses the charging button. If the charging button is pressed, it is determined that there is instruction information indicating that the vehicle to be charged starts charging. Or, detect whether there is a vehicle parked at the set position. If there is a vehicle parked at the set position, then detect whether the user of the vehicle presses the charging button. If the charging button is pressed, it is determined that there is instruction information indicating that the vehicle to be charged starts charging.
