[0039] In order to make the objectives, technical solutions and advantages of the present application clearer, the implementation methods of the present application will be further described in detail below with reference to the accompanying drawings.

[0040] In this application, the terms "first", "second", etc. are used to distinguish identical or similar items with substantially the same effects and functions. It should be understood that there is no logical or temporal dependency between "first", "second", and "nth", nor are there any limitations on quantity and execution order.

[0041] In the present application, the term "at least one" means one or more, and the term "plurality" means 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 used for analysis, stored data, displayed data, etc.) and signals involved in this application are all authorized by the user or fully authorized by all parties, and the collection, use and processing of relevant data must comply with relevant laws, regulations and standards of relevant countries and regions.

[0043] Figure 1 Schematic diagram of an implementation environment of a vehicle charging control method provided according to an embodiment of the present application. Figure 1 The implementation environment includes a vehicle 101, an electronic device 102 and a charging station 103, and the vehicle 101 and the electronic device 102 are connected via a wireless network.

[0044] In some embodiments, the electronic device 102 is a smart phone, a tablet computer, a laptop 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 scheduled charging information for the vehicle 101 through the electronic device 102. In some embodiments, the electronic device 102 can also be an on-board terminal of the vehicle 101 itself, that is, the user can set the scheduled charging information for the vehicle 101 with the help of the on-board terminal 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 equipped with a vehicle controller, an on-board 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 on-board charger through the CAN (Controller Area Network) bus. The vehicle controller can also communicate with the user terminal through a wireless network. Accordingly, when the user sets the scheduled charging information through the user terminal or the on-board terminal, the vehicle controller of the vehicle 101 can obtain the scheduled charging information, and when it is detected that the vehicle 101 is connected to the charging pile 103, based on the scheduled charging information, a control instruction is sent to the battery management system so that the on-board charger can charge the power battery using the current output by the charging pile 103 during the charging time period corresponding to the scheduled charging information.

[0046] Figure 2 is a flow chart of a vehicle charging control method provided according to an embodiment of the present application, the method is executed by a vehicle controller of the vehicle, such as Figure 2 As shown, the vehicle charging control method includes the following steps:

[0047] 201. When it is detected that the vehicle is connected to the charging pile, obtain pre-stored scheduled charging information, where the scheduled charging information includes a charging start time and a charging end time.

[0048] In an embodiment 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 so that the vehicle and the charging pile are connected. For charging piles that are not provided with a scheduled charging function, after the charging pile and the vehicle are connected, the charging pile will immediately charge the vehicle. In order to meet the charging needs of users in any time period, the user can set the scheduled charging information for the vehicle through the scheduled charging function provided by the vehicle's on-board terminal or the remote terminal connected to the vehicle. Accordingly, when the vehicle's vehicle controller detects that the vehicle is connected to the charging pile, in order to prevent the charging pile from charging the vehicle immediately, the scheduled charging information can be obtained, so that the vehicle controller can control the on-board charger based on the scheduled charging information to charge the vehicle's power battery using the current output by the charging pile during the charging time period corresponding to the scheduled charging information. Among them, the scheduled 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. When the charging start time has not arrived, send a charging prohibition instruction 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 convert the AC current output by the charging pile to obtain a DC current that is gradually reduced to zero based on the charging request. Since it indicates that the power battery of the vehicle does not need to be charged at this time when the charging start time has not been reached, the vehicle controller can send the prohibition charging instruction to the battery management system to control the vehicle to enter the prohibition charging state in order to prohibit the on-board charger from charging the power battery with the current output by the charging pile.

[0051] 203. When the charging start time arrives, a charging instruction is sent to the battery management system to control the vehicle to enter a charging state.

[0052] In an 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 convert the AC current output by the charging pile to obtain a DC current based on the charging request and gradually adjust it to a preset value. Wherein, the preset value is not zero. Since it is indicated that the power battery of the vehicle needs to be charged at this time when the charging start time is reached, the vehicle controller can send the charging instruction to the battery management system to control the charging state of the vehicle in order to allow the on-board charger to charge the power battery using the current output by the charging pile. Wherein, the charging end condition of the vehicle includes reaching the charging end time.

[0053] The embodiment of the present application provides a vehicle charging control method, which obtains the scheduled charging information set by the user, so that the vehicle controller of the vehicle can control the state of the vehicle by sending instructions to the battery management system of the vehicle, and then control the vehicle's on-board charger to charge with the current output by the charging pile during the charging time period indicated by the scheduled charging information. The above process can realize the scheduled charging of the vehicle without modifying the charging pile, which not only saves hardware costs, but also enables users to flexibly set the charging time of the vehicle according to their own charging needs, and then control the vehicle to charge during the low-peak period of electricity consumption, thereby saving the charging cost of the vehicle.

[0054] Figure 3 is a flow chart of another vehicle charging control method provided according to an embodiment of the present application, the method being executed by a vehicle controller of the vehicle, such as Figure 3 As shown, the vehicle charging control method includes the following steps:

[0055] 301. When it is detected that the vehicle is connected to the charging pile, obtain pre-stored scheduled charging information, where the scheduled charging information includes a charging start time and a charging end time.

[0056] In the embodiment of the present application, the process of obtaining the pre-stored scheduled charging information is the same as the above step 201 and will not be described in detail 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 vehicle's on-board charger can monitor the CC (charging connection confirmation) signal of the charging interface to confirm whether the physical connection between the charging gun and the charging interface is normal. If the physical connection is confirmed to be 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 been successfully connected to the charging pile. If the physical connection is confirmed to be abnormal, 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 been successfully connected to the charging pile.

[0058] In some embodiments, the vehicle controller can promptly remind the user when the vehicle is not connected to the charging pile. Accordingly, when it is detected that the vehicle is not connected to the charging pile, the vehicle controller obtains the running state of the vehicle; when the running state is the startup state, the second prompt information is sent to the vehicle's on-board terminal, so that the on-board terminal displays or broadcasts the second prompt information, and the second prompt information is used to prompt that the vehicle is not connected to the charging pile; when the running state is the locked state, the second prompt information is sent to the target terminal, so that the target terminal displays or broadcasts the second prompt information, and the target terminal is any remote terminal connected to the vehicle. Among them, the vehicle is not connected to the charging pile, including two situations: the user has not inserted the charging gun of the charging pile into the charging port of the vehicle and the user has inserted the charging gun into the charging port but the connection is unsuccessful. The startup state means that the vehicle is stationary but the vehicle power is not turned off, and the locked state means that the vehicle is stationary but the vehicle power is turned off. When the running state of the vehicle is the startup state, it indicates that the user has not left the vehicle, so the vehicle controller can send a second prompt information to the vehicle's on-board terminal to prompt the user that the vehicle is not connected to the charging pile. When the vehicle is in a locked state, it indicates that the user has left the vehicle, so the vehicle controller can send a second prompt message to the remote terminal connected to the vehicle to remind the user that the vehicle is not yet connected to the charging pile. By selectively sending the second prompt message to the vehicle terminal and the remote terminal according to the vehicle's operating state, the vehicle controller can promptly remind the user that the vehicle is not connected to the charging pile in different situations, thereby avoiding the occurrence of charging failure due to failure to connect 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 port of the vehicle, and then start the scheduled charging function to set the scheduled charging information for the vehicle, or first start the scheduled charging function to set the scheduled charging information for the vehicle, and then insert the charging gun of the charging pile into the charging port of the vehicle. The embodiment of the present application does not limit the order of these two processes.

[0060] In some embodiments, when the user sets the scheduled charging information for the vehicle through the predictive 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 scheduled charging function of the vehicle, the vehicle controller determines at least one candidate charging time period based on multiple 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 scheduled charging information corresponding to the selected candidate charging time period as the scheduled charging information of the vehicle. Among them, the historical charging record includes the historical charging start time and the historical charging end time of the vehicle. The vehicle controller can determine multiple historical charging time periods of the vehicle based on multiple historical charging records. Since the vehicle is a commuting vehicle for the user, the charging time period set by the user for it is basically fixed, so the vehicle controller can determine the historical charging time period of the vehicle as a candidate charging time period and send it to the vehicle terminal or the target terminal for the user to view. When 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 candidate charging time period selected by the user to the vehicle controller, so that the vehicle controller can obtain the vehicle's scheduled charging information based on the candidate charging time period. By determining the historical charging time period corresponding to the vehicle's historical charging records as the candidate charging time period, at least one candidate charging time period can be automatically recommended to the user without the need for manual setting by the user, thereby realizing intelligent scheduled charging settings and improving the user experience.

[0061] Optionally, the vehicle controller can determine at least one candidate charging time period based on multiple historical charging time periods of the vehicle and the start time of the scheduled charging function, that is, it can determine the historical charging time period that belongs to the same day of the week as the start time as the candidate charging time period for this scheduled charging. If the user starts the scheduled 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 also includes the historical charging amount of the vehicle in the historical charging time period. The vehicle controller can sort at least one candidate charging time period from high to low according to the historical charging amount, and send 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 give priority to displaying 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, when it is detected that the vehicle has been connected to the charging pile, the vehicle controller determines the charging time required to fully charge the power battery of the vehicle based on the power of the vehicle; when the charging time corresponding to the scheduled charging information is less than the charging time required to fully charge the power battery of the vehicle, the vehicle controller sends a third prompt message to the vehicle terminal or the target terminal of the vehicle, so that the vehicle terminal or the target terminal displays or broadcasts the third prompt message, and the third prompt message is used to prompt to postpone the end time of the vehicle's charging, or to advance the start time of the vehicle's charging, and the target terminal is any remote terminal connected to the vehicle. Among them, when the vehicle is connected to the charging pile, it means that the vehicle is in a stationary state before the charging is completed, so the vehicle controller can obtain the current power of the vehicle, that is, the remaining power of the vehicle, and then can determine the charging time required to fully charge the power battery of the vehicle based on the remaining power, and the charging time is positively correlated with the remaining power. The vehicle controller can determine the charging time corresponding to the scheduled charging information based on the predicted charging start time and charging end time of the charging information. When the charging time is less than the charging time required to fully charge the power battery, it indicates that the vehicle cannot be fully charged within the charging time period corresponding to the scheduled charging information. Therefore, the vehicle controller can send a third prompt message to the vehicle terminal or the target terminal to prompt the user to adjust the charging start time or charging end time in the scheduled charging information. By determining the charging time required to fully charge the power battery based on the remaining power after the vehicle is connected to the charging pile, it is possible to more accurately determine whether the power battery can be fully charged within the charging time period corresponding to the scheduled charging information, and then accurately and timely send prompt information to prompt the user to adjust the scheduled charging information in a timely manner to avoid the situation where the user's travel is affected by the vehicle's power battery not being fully charged.

[0064] 302. When the charging start time has not arrived, 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 an embodiment of the present application, after the vehicle is connected to the charging pile, the vehicle's onboard charger can convert the AC power output by the charging pile into DC power suitable for charging the vehicle's power battery. The vehicle's battery management system 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 onboard charger can control the output DC current by adjusting the internal circuit to keep it consistent with the charging request current value carried by the charging request.

[0066] Since the charging start time has not been reached, it indicates that the vehicle's power battery does not need to be charged at this time. Therefore, the vehicle controller can send a prohibit charging instruction to the battery management system to control the vehicle to enter a prohibit charging state. Among them, the prohibit 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 vehicle's on-board charger. Accordingly, after receiving the prohibit 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 zero, so that the on-board charger will gradually reduce the output charging current to zero based on the charging request. That is, when the vehicle is in a prohibit charging 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. When the charging start time arrives, a charging instruction is sent to the battery management system to control the vehicle to enter a charging state.

[0068] In an embodiment of the present application, when the charging start time is reached, it indicates that the vehicle's power battery needs to be charged at this time, so the vehicle controller can send the charging instruction to the battery management system to control the charging state of the vehicle. Among them, 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, and 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 a preset value, so that the on-board charger adjusts the output charging current to a preset value based on the charging request. That is, when the vehicle is in a 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 scheduled charging information for the vehicle during the vehicle charging process. Accordingly, in response to the vehicle receiving a scheduled charging request in the charging state, when the charging start time carried by the scheduled charging request is earlier than the pre-stored charging end time, the vehicle controller sends a prohibit charging instruction to the battery management system to control the vehicle to enter the prohibited charging state; when the charging start time carried by the scheduled 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. Among them, the scheduled charging request carries the scheduled charging information set by the user during the vehicle charging process, and the scheduled charging information also includes the charging start time and the charging end time. If the charging start time carried by the scheduled charging request is earlier than the charging end time in the pre-stored scheduled charging information, it indicates that the charging process of the vehicle needs to be interrupted, so the vehicle controller can send a prohibit charging instruction to the battery management system again to control the vehicle to switch from the charging state to the prohibited charging state. And, after waiting for a period of time, that is, when the charging start time carried by the scheduled charging request is reached, the vehicle controller can resend the charging instruction 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 charging end time carried in the scheduled charging request after the vehicle enters the charging state, the user's charging needs in any time period can be met, allowing the user to effectively avoid peak electricity consumption and reduce the vehicle's charging costs.

[0070] Optionally, if the charging start time carried in the scheduled charging request is later than the charging end time in the pre-stored scheduled charging information, it indicates that the vehicle controller does not need the charging process of the terminal vehicle. Therefore, the vehicle controller only needs to wait for the end of this charging process, and then control the vehicle to charge the vehicle in the charging time period between the charging start time and the charging end time carried in the scheduled charging request.

[0071] 304. When the vehicle is in a charging state, if the charging end time is reached and the vehicle power level indicates that the vehicle's power battery is fully charged, the vehicle is controlled to enter a dormant state.

[0072] In an embodiment of the present application, when the vehicle is in a charging state, if the charging end time is reached, it indicates that the charging process of the vehicle is completed. If the vehicle's power level indicates that the vehicle's power battery is fully charged at this time, the vehicle controller can control the vehicle to enter a sleep state to reduce the power consumption of the power battery.

[0073] Optionally, when the vehicle is in a charging state, the vehicle controller can obtain the vehicle's power level in real time. When the power level indicates that the vehicle's power battery is fully charged, if the charging end time has not yet been reached, the vehicle controller can also control the vehicle to enter a dormant state.

[0074] In some embodiments, the vehicle controller can send a prompt message to ask the user whether to continue charging when the vehicle's power battery is not fully charged. Accordingly, when the vehicle is in a charging state, if the charging end time is reached and the vehicle's power level indicates that the vehicle's power battery is not fully charged, the vehicle controller sends a first prompt message to the target terminal, and the first prompt message is used to prompt whether to continue charging the vehicle. The target terminal is any remote terminal connected to the vehicle; in response to receiving the confirmation message returned by the target terminal, the vehicle controller can continue to send charging instructions to the battery management system to control the vehicle to continue to be in a charging state. Among them, after the user inserts the charging gun of the charging pile into the vehicle, he usually locks the vehicle and leaves, and retrieves the vehicle after the vehicle is charged. Therefore, if the vehicle's power battery is not fully charged after the charging end time is reached, the vehicle controller can send a first prompt message to the remote terminal connected to the vehicle to prompt the user that the power is not fully charged and whether it is necessary to continue charging the vehicle. When the user performs a confirmation operation on the first prompt message through the remote terminal, the remote terminal can return a confirmation message to the vehicle control to instruct the vehicle controller to control the vehicle to continue to be in a charging state. By promptly reminding the user whether to continue charging the vehicle when the charging end time is reached but the vehicle's power battery is not fully charged, it is possible to avoid the situation where the user's travel is affected by the vehicle's power battery not being fully charged.

[0075] In some embodiments, the reserved charging information also includes the charging end power, and the charging end condition of the vehicle also includes the vehicle's power reaching the charging end power. Accordingly, when the vehicle is in a charging state, if the charging end time has not been reached and the vehicle's power reaches the charging end power, the vehicle controller sends a prohibit charging instruction to the battery management system to control the vehicle to enter a prohibit charging state; if the charging end time has been reached and the vehicle's power has not reached the charging end power, the charging instruction continues to be sent to the battery management system to control the vehicle to continue to be in a charging state. Wherein, when the vehicle is in a charging state, the vehicle controller can obtain the vehicle's power in real time. When the power reaches the charging end power, if the charging end time has not been reached, the vehicle controller can end the vehicle's charging process in advance, that is, it can send a prohibit charging instruction to the battery management system again to control the vehicle to switch from the charging state to the prohibit charging state. When the charging end time has been reached but the power has not reached the charging end power, in order to extend the vehicle's charging process, the vehicle controller can continue to send charging instructions to the battery management system to control the vehicle to continue to be in a charging state. By obtaining the end-of-charging power set by the user for the vehicle, the vehicle controller can accurately control the vehicle's charging process based on the end-of-charging power, thereby avoiding overcharging of the vehicle's power battery and ensuring the safety and life of the battery.

[0076] In order to facilitate understanding of the vehicle charging control scheme provided in the embodiment of the present application, the embodiment of the present application also provides a flow chart and a system structure diagram of the vehicle charging control. Figure 4 FIG. 1 is a flow chart of a vehicle charging control process provided according to an embodiment of the present application. Figure 4 As shown, the user sets the charging mode through the vehicle's on-board terminal or the remote terminal connected to the vehicle. In the case of selecting the immediate charging mode, if the charging pile connected to the vehicle is detected to be unobstructed, the vehicle controller can control the on-board charger to immediately use the current output by the charging pile to charge the vehicle's power battery. In the case of selecting the scheduled charging mode, the user can continue to set the scheduled charging information for the vehicle through the on-board terminal or the remote terminal, and the scheduled charging information includes the charging start time and the charging end time. After the setting is completed, the on-board terminal or the remote terminal can send the scheduled charging information to the vehicle's vehicle controller. If the vehicle controller detects that the charging pile connected to the vehicle is unobstructed, it indicates that the user's appointment is successful. The vehicle controller can send a prohibition charging instruction "Stop Charging Request" to the battery management system before the charging start time is reached. After receiving the prohibition charging instruction, the battery management system changes the charging request current value to 0A (ampere). After receiving the charging request current value, the on-board charger can control the output current to gradually decrease to 0A. When the charging start time is reached, the vehicle controller stops sending the prohibition charging command and instead sends the charging command "Charging Request" to the battery management system. After receiving the charging command, the battery management system can change the charging request current value from 0A to the actual current value. After receiving the charging request current value, the on-board charger can control the output current to gradually change from 0A to the actual current value. After the charging end time is reached, if the vehicle's power has reached 100%, the vehicle controller can control other controllers of the vehicle to enter a dormant state. Figure 5 1 is a system structure diagram of a vehicle charging control system provided according to an embodiment of the present application. Figure 5 As shown, the vehicle's VCU (Vehicle Control Unit) communicates with the BMS (Battery Management System), OBC (On-Board Charger) and IHU (In-Vehicle Infotainment Unit) via the CAN bus. The VCU communicates with the remote terminal via a wireless network. The IHU is used to manage the vehicle's onboard terminals.

[0077] The embodiment of the present application provides a vehicle charging control method, which obtains the scheduled charging information set by the user, so that the vehicle controller of the vehicle can control the state of the vehicle by sending instructions to the battery management system of the vehicle, and then control the vehicle's on-board charger to charge with the current output by the charging pile during the charging time period indicated by the scheduled charging information. The above process can realize the scheduled charging of the vehicle without modifying the charging pile, which not only saves hardware costs, but also enables users to flexibly set the charging time of the vehicle according to their own charging needs, and then control the vehicle to charge during the low-peak period of electricity consumption, thereby saving the charging cost of the vehicle.
