[0039] In order to make the purpose, technical solutions and advantages of the application more clear, the embodiments of the application will be further described in detail with reference to the drawings.

[0040] The terms "first", "second", and the like in the present application are used to distinguish the same or similar items with substantially the same function, and it should be understood that there is no logical or time sequence relationship between "first", "second", and "n", and the number and execution order are not limited.

[0041] The term "at least one" in the present application means one or more, and the meaning of "multiple" is two or more.

[0042] It should be noted that the information (including but not limited to user device information, user personal information, etc.), data (including but not limited to data for analysis, stored data, displayed data, etc.) and signals involved in the present application are authorized by the user or fully authorized by all parties, and the collection, use and processing of related data need to comply with relevant national and regional laws, regulations and standards.

[0043] Figure 1 is an implementation environment schematic diagram of a vehicle charging control method according to an embodiment of the present application. Referring to Figure 1 , the implementation environment includes a vehicle 101, an electronic device 102, and a charging pile 103, and the vehicle 101 and the electronic device 102 are connected through a wireless network.

[0044] In some embodiments, the electronic device 102 is a smart phone, a tablet computer, a notebook computer, a desktop computer, a smart watch, etc., but is not limited thereto. For example, the electronic device 102 is a terminal used by the driver of the vehicle 101, and the driver can set the vehicle 101 with the electronic device 102 to set the reservation charging information of the vehicle 101. In some embodiments, the electronic device 102 can also be a vehicle terminal carried by the vehicle 101, that is, the user can set the vehicle 101 with the vehicle terminal of the vehicle 101 to set the reservation charging information of the vehicle 101.

[0045] In some embodiments, the vehicle 101 is a new energy vehicle, such as a pure electric vehicle, a plug-in hybrid electric vehicle, a fuel cell electric vehicle, etc. The vehicle 101 is configured with a vehicle controller, a vehicle-mounted charger, a power battery, and a battery management system for managing the power battery. Among them, the vehicle controller can communicate with the vehicle terminal, the battery management system, and the vehicle-mounted charger through the CAN (Controller Area Network) bus. The vehicle controller can also communicate with the user terminal through a wireless network. Accordingly, in the case that the user sets the reservation charging information through the user terminal or the vehicle terminal, the vehicle controller of the vehicle 101 can obtain the reservation charging information, and in the case that the vehicle 101 is detected to be connected to the charging pile 103, based on the reservation charging information, the vehicle controller sends a control instruction to the battery management system to make the vehicle-mounted charger charge the power battery with the current output by the charging pile 103 within the charging time period corresponding to the reservation charging information.

[0046] Figure 2 A flowchart of a vehicle charging control method is provided according to an embodiment of the present application, the method is executed by a vehicle controller of a vehicle, as shown in Figure 2 The vehicle charging control method includes the following steps:

[0047] 201. In the case that the vehicle is detected to be connected to the charging pile, the pre-stored reservation charging information is obtained, and the reservation charging information includes the charging start time and the charging end time.

[0048] In the embodiments of the present application, when the vehicle needs to be charged, the user needs to park the vehicle at the charging pile and insert the charging gun of the charging pile into the charging interface of the vehicle to establish a connection between the vehicle and the charging pile. For the charging pile which is not provided with the reservation charging function, after the charging pile is connected with the vehicle, the charging pile will immediately charge the vehicle. In order to meet the charging needs of the user at any time period, the user can set the reservation charging information for the vehicle through the reservation charging function provided by the vehicle terminal of the vehicle or the remote terminal connected to the vehicle. Accordingly, in the case that the vehicle controller of the vehicle detects that the vehicle is connected to the charging pile, in order not to make the charging pile immediately charge the vehicle, the reservation charging information can be obtained, so that the vehicle controller can control the vehicle-mounted charger to charge the power battery of the vehicle with the current output by the charging pile within the charging time period corresponding to the reservation charging information based on the reservation charging information. Among them, the reservation charging information includes the charging start time and the charging end time of the vehicle. The time period between the charging start time and the charging end time is the charging time period reserved by the user for the vehicle.

[0049] 202. In the case that the charging start time has not arrived, a charging prohibition instruction is sent to the battery management system of the vehicle to control the vehicle to enter a charging prohibition state.

[0050] In the embodiment of the present application, the prohibition charging instruction is used to instruct the battery management system to set the charging request current value carried by the charging request to zero, and send the charging request to the on-board charger of the vehicle, so that the on-board charger can gradually reduce the direct current converted from the alternating current output by the charging pile to zero based on the charging request. Since the charging start time is not reached, it indicates that the power battery of the vehicle does not need to be charged at this time, therefore, in order to prohibit the on-board charger from charging the power battery with the current output by the charging pile, the vehicle controller can send the prohibition charging instruction to the battery management system to control the vehicle to enter the prohibition charging state.

[0051] 203、In the case where the charging start time is reached, a charging instruction is sent to the battery management system to control the vehicle to enter the charging state.

[0052] In the embodiment of the present application, the charging instruction is used to instruct the battery management system to set the charging request current value carried by the charging request to a preset value, and send the charging request to the on-board charger, so that the on-board charger can gradually adjust the direct current converted from the alternating current output by the charging pile to the preset value based on the charging request. The preset value is not zero. Since the charging start time is reached, it indicates that the power battery of the vehicle needs to be charged at this time, therefore, in order to allow the on-board charger to charge the power battery with the current output by the charging pile, the vehicle controller can send the charging instruction to the battery management system to control the vehicle to enter the charging state. The charging end condition of the vehicle includes the charging end time.

[0053] The embodiment of the present application provides a vehicle charging control method, by obtaining the reservation charging information set by the user, so that the vehicle controller of the vehicle can control the state of the vehicle by sending an instruction to the battery management system of the vehicle, and then control the on-board charger of the vehicle to charge with the current output by the charging pile in the charging time period indicated by the reservation charging information. The above process does not need to modify the charging pile, and can realize the reservation charging of the vehicle, not only saving the hardware cost, but also allowing the user to flexibly set the charging time of the vehicle according to the charging demand, and then controlling the vehicle to charge in the low power consumption period, thereby saving the charging cost of the vehicle.

[0054] Figure 3 is a flowchart of another vehicle charging control method provided by the embodiment of the present application, which is executed by the vehicle controller of the vehicle, as shown in Figure 3 The vehicle charging control method comprises the following steps:

[0055] 301、In the case of detecting that the vehicle has connected the charging pile, the pre-stored reservation charging information is acquired, and the reservation charging information includes a charging start time and a charging end time.

[0056] In the embodiments of the present application, the process of acquiring the pre-stored reservation charging information is the same as step 201 described above, and will not be described here.

[0057] It should be noted that when the user inserts the charging gun of the charging pile into the charging interface of the vehicle, the on-board charger of the vehicle can monitor the CC (charging connection confirmation) signal of the charging interface to confirm whether the physical connection of the charging gun and the charging interface is normal. In the case of confirming that the physical connection is normal, the on-board charger can send a connection success signal to the vehicle controller through the CAN bus to inform the vehicle controller that the vehicle has successfully connected the charging pile. In the case of confirming that the physical connection is not normal, the on-board charger can also send a connection failure signal to the vehicle controller to inform the vehicle controller that the vehicle has not successfully connected the charging pile.

[0058] In some embodiments, the vehicle controller can timely remind the user in the case that the vehicle is not connected to the charging pile. Accordingly, in the case of detecting that the vehicle is not connected to the charging pile, the vehicle controller acquires the running state of the vehicle; in the case of the running state being a start state, the vehicle controller sends second prompt information to the on-board terminal of the vehicle to make the on-board terminal display or broadcast the second prompt information, and the second prompt information is used to prompt that the vehicle is not connected to the charging pile; in the case of the running state being a lock state, the vehicle controller sends the second prompt information to a target terminal to make the target terminal display or broadcast the second prompt information, and the target terminal is any remote terminal connected to the vehicle. The vehicle not being connected to the charging pile includes two cases: the user has not inserted the charging gun of the charging pile into the charging interface of the vehicle and the user has inserted the charging gun into the charging interface but the connection is not successful. The start state means that the vehicle is stationary but the power of the vehicle is not turned off, and the lock state means that the vehicle is stationary but the power of the vehicle is turned off. In the case of the running state of the vehicle being the start state, it indicates that the user has not left the vehicle, and therefore the vehicle controller can send the second prompt information to the on-board terminal of the vehicle to prompt the user that the vehicle is not connected to the charging pile. In the case of the running state of the vehicle being the lock state, it indicates that the user has left the vehicle, and therefore the vehicle controller can send the second prompt information to the remote terminal connected to the vehicle to prompt the user that the vehicle has not connected to the charging pile. By selectively sending the second prompt information to the on-board terminal and the remote terminal according to the running state of the vehicle, the vehicle controller can timely remind the user that the vehicle is not connected to the charging pile in different cases, thereby avoiding the situation that the charging fails due to not being connected to the charging pile.

[0059] It should be noted that the user can first insert the charging gun of the charging pile into the charging interface of the vehicle, and then start the reservation charging function to set the reservation charging information for the vehicle, or first start the reservation charging function to set the reservation charging information for the vehicle, and then insert the charging gun of the charging pile into the charging interface of the vehicle. The application embodiments do not limit the order of the two processes.

[0060] In some embodiments, when the user sets the reservation charging information for the vehicle through the prediction charging function provided by the vehicle terminal or the remote terminal, the vehicle controller can recommend at least one candidate charging time period to the user for selection. Accordingly, in response to the start of the reservation charging function of the vehicle, the vehicle controller determines at least one candidate charging time period based on a plurality of historical charging records of the vehicle; then, the vehicle controller sends at least one candidate charging time period to the vehicle terminal or the target terminal of the vehicle, so that the vehicle terminal or the target terminal displays at least one candidate charging time period, and the target terminal is any remote terminal connected to the vehicle; finally, in response to any candidate charging time period being selected, the vehicle controller sets the reservation charging information corresponding to the selected candidate charging time period as the reservation charging information of the vehicle. The historical charging record includes the historical charging start time and the historical charging end time of the vehicle. The vehicle controller can determine a plurality of historical charging time periods of the vehicle based on a plurality of historical charging records. Since the vehicle is the user's commuter vehicle, the user sets the charging time period of the vehicle basically fixedly unchanged, so the vehicle controller can determine the historical charging time period of the vehicle as the candidate charging time period and send it to the vehicle terminal or the target terminal for the user to view. In the case where the user selects any candidate charging time period through the vehicle terminal or the target terminal, the vehicle terminal or the target terminal can return the selected candidate charging time period to the vehicle controller, so that the vehicle controller can obtain the reservation charging information of the vehicle based on the candidate charging time period. By determining the historical charging time period corresponding to the historical charging record of the vehicle as the candidate charging time period, at least one candidate charging time period can be automatically recommended to the user without manual setting, thereby realizing intelligent reservation charging setting and improving user experience.

[0061] Optionally, the vehicle controller can determine at least one candidate charging time period based on a plurality of historical charging time periods of the vehicle and the start time of the reservation charging function, that is, the historical charging time period belonging to the same day of the week as the start time can be determined as the candidate charging time period of this reservation charging. For example, if the user starts the reservation charging function on Sunday, the vehicle controller can determine the historical charging time period of the vehicle on the previous Sunday as the candidate charging time period.

[0062] Optionally, the historical charging record further includes a historical charging amount of the vehicle in the historical charging time period. The vehicle controller can sort the at least one candidate charging time period in descending order of the historical charging amount, and send the at least one candidate charging time period to the vehicle terminal and the target terminal according to the sorting result, so that the vehicle terminal and the target terminal can preferentially display the candidate charging time period with a higher historical charging amount.

[0063] In some embodiments, since the power of the vehicle changes as the vehicle travels, in order to ensure that the power battery of the vehicle can be fully charged within the charging time period set by the user, the vehicle controller of the vehicle can detect whether the charging time period set by the user is sufficient to fully charge the power battery after the vehicle is connected to the charging pile. Accordingly, in the case where it is detected that the vehicle has been connected to the charging pile, the vehicle controller determines the charging duration required to fully charge the power battery of the vehicle based on the power of the vehicle; in the case where the charging duration corresponding to the reservation charging information is less than the charging duration required to fully charge the power battery of the vehicle, the vehicle controller sends third prompt information to the vehicle terminal or the target terminal of the vehicle to make the vehicle terminal or the target terminal display or broadcast the third prompt information, the third prompt information being used to prompt to delay the charging end time of the vehicle or to advance the charging start time of the vehicle, the target terminal being any remote terminal connected by the vehicle. In the case where the vehicle is connected to the charging pile, it indicates that the vehicle is in a stationary state before the charging ends, so the vehicle controller can obtain the power of the current vehicle, i.e., the remaining power of the vehicle, and then determine the charging duration required to fully charge the power battery of the vehicle based on the remaining power, the charging duration being positively correlated with the remaining power. The vehicle controller can determine the charging duration corresponding to the reservation charging information based on the charging start time and the charging end time of the predicted charging information. In the case where the charging time is less than the charging duration required to fully charge the power battery, it indicates that the vehicle cannot be fully charged within the charging time period corresponding to the reservation charging information, so the vehicle controller can send the third prompt information to the vehicle terminal or the target terminal to prompt the user to adjust the charging start time or the charging end time in the reservation charging information. By determining the charging duration required to fully charge the power battery based on the remaining power after the vehicle is connected to the charging pile, the power battery can be more accurately determined whether it can be fully charged within the charging time period corresponding to the reservation charging information, and the prompt information can be accurately and timely sent to prompt the user to timely adjust the reservation charging information, thereby avoiding the situation that the user's trip is affected due to the power battery of the vehicle not being fully charged.

[0064] 302、in the case where the charging start time has not been reached, send a charging prohibition instruction to the battery management system of the vehicle to control the vehicle to enter a charging prohibition state.

[0065] In the embodiment of the present application, after the vehicle establishes a connection with the charging pile, the on-board charger of the vehicle can convert the alternating current output by the charging pile into direct current suitable for charging the power battery of the vehicle. The battery management system of the vehicle can determine the appropriate charging current by monitoring various parameters of the power battery. Accordingly, after receiving the charging request sent by the battery management system, the on-board charger can control the size of the output direct current by adjusting the internal circuit, so as to make it consistent with the charging request current value carried by the charging request.

[0066] Since it is indicated that the power battery of the vehicle does not need to be charged at this time in the case where the charging start time is not reached, the vehicle controller can send a charging prohibition instruction to the battery management system to control the vehicle to enter a charging prohibition state. The charging prohibition instruction is used to instruct the battery management system to set the charging request current value carried by the charging request to zero and send the charging request to the on-board charger of the vehicle. Accordingly, after receiving the charging prohibition instruction, the battery management system can set the charging request current value in the charging request to be sent to the on-board charger to zero, so that the on-board charger gradually reduces the output charging current to zero based on the charging request. That is, in the case where the vehicle is in the charging prohibition state, the vehicle controller can prohibit the on-board charger from charging the power battery using the current output by the charging pile.

[0067] 303、In the case where the charging start time is reached, a charging instruction is sent to the battery management system to control the vehicle to enter a charging state.

[0068] In the embodiment of the present application, in the case where the charging start time is reached, it is indicated that the power battery of the vehicle needs to be charged at this time, and therefore the vehicle controller can send the charging instruction to the battery management system to control the vehicle to enter a charging state. The charging instruction is used to instruct the battery management system to set the charging request current value carried by the charging request to a preset value, and send the charging request to the on-board charger, wherein the preset value is not zero. Accordingly, after receiving the charging instruction, the battery management system can set the charging request current value in the charging request to be sent to the on-board charger to the preset value, so that the on-board charger adjusts the output charging current to the preset value based on the charging request. That is, in the case where the vehicle is in the charging state, the vehicle controller can allow the on-board charger to charge the power battery using the current output by the charging pile.

[0069] In some embodiments, the user can re-set the reservation charging information for the vehicle during the charging process of the vehicle. Accordingly, in response to the vehicle receiving a reservation charging request in the charging state, if the charging start time carried by the reservation charging request is earlier than the pre-stored charging end time, the vehicle controller sends a charging prohibition instruction to the battery management system to control the vehicle to enter the charging prohibition state; if the charging start time carried by the reservation charging request is reached, the vehicle controller sends a charging instruction to the battery management system to control the vehicle to enter the charging state. The reservation charging request carries the reservation charging information set by the user during the charging process of the vehicle, and the reservation charging information also includes the charging start time and the charging end time. If the charging start time carried by the reservation charging request is earlier than the charging end time in the pre-stored reservation charging information, it indicates that the charging process of the vehicle needs to be interrupted, and therefore the vehicle controller can send a charging prohibition instruction again to the battery management system to control the vehicle to switch from the charging state to the charging prohibition state. Moreover, after waiting for a period of time, i.e., when the charging start time carried by the reservation charging request is reached, the vehicle controller can send a charging instruction again to the battery management system to control the vehicle to re-enter the charging state. By changing the charging time of the vehicle based on the charging start time and the charging end time carried by the reservation charging request after the vehicle enters the charging state, the charging demand of the user at any time period can be met, so that the user can effectively avoid the peak electricity consumption period, and the charging cost of the vehicle is reduced.

[0070] Optionally, if the charging start time carried by the reservation charging request is later than the charging end time in the pre-stored reservation charging information, it indicates that the vehicle controller does not need to terminate the charging process of the vehicle, and therefore the vehicle controller only needs to wait for the end of the current charging process, and then control the vehicle to be charged in the charging time period between the charging start time and the charging end time carried by the reservation charging request.

[0071] 304、In the case where the vehicle is in the charging state, if the charging end time is reached and the power of the vehicle indicates that the power battery of the vehicle is fully charged, the vehicle is controlled to enter the hibernation state.

[0072] In the embodiments of the present application, in the case where the vehicle is in the charging state, if the charging end time is reached, it indicates that the charging process of the vehicle is completed, and if the power of the vehicle indicates that the power battery of the vehicle is fully charged at this time, the vehicle controller can control the vehicle to enter the hibernation state to reduce the power consumption of the power battery.

[0073] Optionally, in the case where the vehicle is in the charging state, the vehicle controller can acquire the power of the vehicle in real time. In the case where the power indicates that the power battery of the vehicle is fully charged, if the charging end time has not been reached, the vehicle controller can also control the vehicle to enter the hibernation state.

[0074] In some embodiments, the vehicle controller is capable of sending a prompt information to inquire the user whether to continue charging when the power battery of the vehicle is not full. Accordingly, when the vehicle is in the charging state, if the charging end time is reached and the power of the vehicle indicates that the power battery of the vehicle is not full, the vehicle controller sends a first prompt information to the target terminal, the first prompt information is used to prompt whether to continue charging the vehicle, and the target terminal is any remote terminal connected to the vehicle; in response to receiving the confirmation information returned by the target terminal, the vehicle controller is capable of continuing to send the charging instruction to the battery management system to control the vehicle to continue in the charging state. Wherein, after the user inserts the charging gun of the charging pile for the vehicle, the user usually locks the vehicle and leaves, and then retrieves the vehicle after the vehicle charging is completed. Therefore, if the power battery of the vehicle is not full after the charging end time is reached, the vehicle controller can send a first prompt information to the remote terminal connected to the vehicle to prompt the user whether the power is full and whether to continue charging the vehicle. In the case that the user performs a confirmation operation on the first prompt information through the remote terminal, the remote terminal can return a confirmation information to the vehicle controller to indicate the vehicle controller to control the vehicle to continue in the charging state. By timely reminding the user whether to continue charging the vehicle when the charging end time is reached but the power battery of the vehicle is not full, the situation that the user's travel is affected due to the power battery of the vehicle not being full can be avoided.

[0075] In some embodiments, the reservation charging information further includes a charging end power, and the charging end condition of the vehicle further includes that the power of the vehicle reaches the charging end power. Accordingly, when the vehicle is in the charging state, if the charging end time is not reached and the power of the vehicle reaches the charging end power, the vehicle controller sends a charging prohibition instruction to the battery management system to control the vehicle to enter the charging prohibition state; if the charging end time is reached and the power of the vehicle does not reach the charging end power, the vehicle controller continues to send the charging instruction to the battery management system to control the vehicle to continue in the charging state. Wherein, when the vehicle is in the charging state, the vehicle controller is capable of acquiring the power of the vehicle in real time. In the case that the power reaches the charging end power, if the charging end time is not reached, the vehicle controller can end the charging process of the vehicle in advance, that is, the vehicle controller can send a charging prohibition instruction to the battery management system again to control the vehicle to switch from the charging state to the charging prohibition state. In the case that the charging end time is reached but the power does not reach the charging end power, the vehicle controller can continue to send the charging instruction to the battery management system to control the vehicle to continue in the charging state in order to prolong the charging process of the vehicle. By acquiring the charging end power set by the user for the vehicle, the vehicle controller can accurately control the charging process of the vehicle based on the charging end power, so as to avoid the situation that the power battery of the vehicle is overcharged, thereby ensuring the safety and life of the battery.

[0076] In order to facilitate understanding of the vehicle charging control scheme provided by the embodiments of the present application, the embodiments of the present application further provide a flowchart and a system structure diagram of vehicle charging control. Among them, Figure 4 is a flowchart of vehicle charging control according to an embodiment of the present application. As shown in Figure 4 , a user sets a charging mode through a vehicle terminal or a remote terminal connected to the vehicle. In the case of selecting an immediate charging mode, if it is detected that there is no obstacle in the charging pile connected to the vehicle, the vehicle controller can control the on-board charger to immediately charge the power battery of the vehicle using the current output by the charging pile. In the case of selecting a reservation charging mode, the user can continue to set reservation charging information for the vehicle through the vehicle terminal or the remote terminal, and the reservation charging information includes a charging start time and a charging end time. After the setting is completed, the vehicle terminal or the remote terminal can send the reservation charging information to the vehicle controller. If the vehicle controller detects that there is no obstacle in the charging pile connected to the vehicle, it indicates that the user's reservation is successful. The vehicle controller can send a charging prohibition instruction "Stop Charging Request" to the battery management system before the charging start time. After the battery management system receives the charging prohibition instruction, the charging request current value is changed to 0A (ampere). After the on-board charger receives the charging request current value, it can control the output current to gradually decrease to 0A. In the case of reaching the charging start time, the vehicle controller stops sending the charging prohibition instruction and sends a charging instruction "Charging Request" to the battery management system. After the battery management system receives the charging instruction, it can change the charging request current value from 0A to the actual current value. After the on-board charger receives the charging request current value, it can control the output current to gradually change from 0A to the actual current value. After reaching the charging end time, if the power of the vehicle has reached 100%, the vehicle controller can control other controllers of the vehicle to enter a sleep state. Figure 5 is a system structure diagram of vehicle charging control according to an embodiment of the present application. As shown in Figure 5 , the VCU (Vehicle Control Unit, vehicle controller) of the vehicle communicates with the BMS (Battery Management System, battery management system), OBC (On-Board Charger, on-board charger) and IHU (In-Vehicle Infotainment Unit, vehicle information entertainment system) through the CAN bus. The VCU communicates with the remote terminal through the wireless network. The IHU is used to manage the vehicle terminal of the vehicle.

[0077] The embodiment of the present application provides a vehicle charging control method, by acquiring the reservation charging information set by a user, so that the vehicle controller can control the state of the vehicle by sending an instruction to the battery management system of the vehicle, and then can control the on-board charger of the vehicle to charge by using the current output by the charging pile in the charging time period indicated by the reservation charging information. The above process does not need to modify the charging pile, and can realize the reservation charging of the vehicle, not only saving the hardware cost, but also enabling the user to flexibly set the charging time of the vehicle according to the charging demand of the user, and then enabling the user to control the vehicle to charge in the low power consumption peak period, so that the charging cost of the vehicle is saved.
