[0020] To make the objectives, technical solutions, and advantages of this application clearer, the embodiments of this application will be described in further detail below with reference to the accompanying drawings.

[0021] First, a brief introduction to the terms used in the embodiments of this application:

[0022] Central Control Unit (IHU): A vehicle-mounted infotainment system with a display screen used to control the operation of other system modules. The display screen shows the human-machine interface.

[0023] Remote controller (Telematics BOX, T-BOX): Used to achieve information synchronization between the central control unit and external mobile devices.

[0024] Central Gateway (CGW): Used to enable information exchange between different system modules within the vehicle.

[0025] Instrument Cluster Module (ICM): Used to display instrument information, including odometer, tachometer, and charging meter.

[0026] Conversion & Distribution Unit (CDU): Internally integrates an on-board charger, DC / DC (Direct Current) converter, and high-voltage distributor to distribute power to various system modules.

[0027] Hybrid Control Unit (HCU): It has power coordination management functions and can perform charging management.

[0028] Battery Management System (BMS): Used to monitor battery status and provide feedback on charging status.

[0029] This application provides a charging control system that can coordinate the work between various system modules and achieve charging control under different charging strategies through central control or remote control.

[0030] See Figure 1 , Figure 1 This is a structural diagram of a charging control system provided in an exemplary embodiment of this application. The system modules in the system include: a central control unit 101, a remote controller 102, a central gateway 103, an instrument module 104, a charging and discharging power distribution unit 105, a hybrid control unit 106, and a battery management unit 107.

[0031] The central control unit 101 is connected to the remote controller 102. The central control unit 101 communicates with the external mobile device through the remote controller 102. The central control unit 101 and the external mobile device are used to synchronize the charging control strategy through the remote controller 102.

[0032] The central control unit 101 and the remote controller 102 are respectively connected to the central gateway 103, and the central gateway 103 is respectively connected to the instrument module 104, the charging and discharging power distribution unit 105, the hybrid control unit 106 and the battery management unit 107.

[0033] The central gateway 103 is used to exchange charging commands and charging information between different system modules.

[0034] The instrument module 104, the charging / discharging power distribution unit 105, the hybrid control unit 106, and the battery management unit 107 are all connected to the central gateway 103. The instrument module 104 is used to display information related to charging and power level, the charging / discharging power distribution unit 105 is used to manage the charging port status, the hybrid control unit 106 is used to control charging enable, and the battery management unit 107 is used to manage battery status.

[0035] In some embodiments, the external mobile device refers to a mobile device with a remote control application installed, such as a smartphone, smartwatch, or tablet. Optionally, the external mobile device and the remote controller 102 can communicate via a wired or wireless network, or via Bluetooth.

[0036] In some embodiments, when the battery power mode is KL30 (Klemme 30, constant power mode), ACC (Accessory, power-on mode), or KL15 (Klemme 15, ignition mode), the central control unit 101 and the external mobile device receive a charging mode setting operation, and then synchronize the charging control strategy through the remote controller 102.

[0037] In one possible application scenario, when an external mobile device establishes a communication connection with the remote controller 102, it can synchronize the charging control strategy with the central control unit 101 in real time through the remote controller 102.

[0038] In other embodiments, the external mobile device receives a charging mode setting operation and stores a charging control strategy when the charging control system is powered off.

[0039] In one possible application scenario, the external mobile device can pre-set a charging control strategy. Subsequently, once a communication connection is established between the external mobile device and the remote controller 102, the external mobile device synchronizes the charging control strategy with the remote controller 102.

[0040] In some embodiments, when the central control unit 101 receives a setting operation for the charging control strategy, it synchronizes the current charging control strategy with the external mobile device through the remote controller 102, so that the charging control strategy displayed on the external mobile device is consistent with the charging control strategy set by the central control unit 101.

[0041] In other embodiments, when an external mobile device receives a setting operation for the charging control strategy, it synchronizes the current charging control strategy with the central control unit 101 via the remote controller 102.

[0042] In some embodiments, the instrument module 104 is used to display the operating status of different system modules, including displaying the plug status sent by the charging and discharging power distribution unit 105, the charging status sent by the hybrid control unit 106, and the battery status sent by the battery management unit 107.

[0043] In some embodiments, the charging modes include an immediate charging mode and a scheduled charging mode. When the charging control system is powered on for the first time, the default charging mode is the immediate charging mode.

[0044] It should be noted that the hybrid control unit 106 is used to manage charging permission, and the charge / discharge power distribution unit 105 controls DC / DC enable during charging.

[0045] This application provides a charging control system capable of flexible charging control. The system's central control unit and remote controller can communicate to synchronize charging strategies, enabling external mobile devices and the central control unit to perform charging control synchronously. The central gateway coordinates information exchange between different system modules, allowing external mobile devices or the central control unit to control the hybrid control unit to charge according to the charging control strategy. Furthermore, it displays charging status feedback from the charging / discharging distribution unit, hybrid control unit, and battery management unit, including charging gun status and battery status, synchronized with the instrument display. This improves the collaboration capabilities between different system modules, thereby enhancing the convenience of switching charging control strategies and ultimately increasing the charging success rate.

[0046] The following application embodiments first describe the command synchronization between the central control unit and the external mobile device from the perspectives of the central control unit and the remote controller. For example, Figure 2 A schematic diagram of the two-way interaction between the central control unit and the remote controller is shown. The diagram shows an external mobile device 200, a central control unit 201, and a remote controller 202.

[0047] 1. Under the scenario where the central control unit 201 synchronously charges the external mobile device 200:

[0048] The central control unit 201 is used to send a charging mode setting command to the remote controller 202 upon receiving a charging mode setting operation. The remote controller 202 is used to synchronize the charging mode setting command to the external mobile device 200.

[0049] In some embodiments, the charging mode setting operation is used to set a charging control strategy, including setting the charging mode and scheduled charging information. Optionally, the charging mode setting operation includes touch operation on the UI (User Interface) of the central control unit 201. Optionally, the UI shortcut interface can provide shortcut controls for quickly switching charging modes.

[0050] In some embodiments, the charging modes include an immediate charging mode and a scheduled charging mode. When the charging control system is powered on for the first time, the charging mode defaults to the immediate charging mode, and there is no scheduled charging information.

[0051] In some embodiments, the charging mode setting instruction is used to instruct the charging control strategy set by the charging mode setting operation. Optionally, when the charging mode setting instruction instructs the charging mode to be set to a scheduled charging mode, the charging mode setting instruction may include scheduled charging information, which is determined according to the charging mode setting operation.

[0052] Optionally, if scheduled charging information exists and the charging mode setting command indicates that the charging mode is set to scheduled charging mode, the scheduled charging information may not be included in the charging mode setting command. In scheduled charging mode, the central control unit 201 sends control commands based on the currently existing scheduled charging information.

[0053] 2. Under the scenario where the external mobile device 200 synchronously charges the central control unit 201:

[0054] The external mobile device 200 is used to send a charging mode setting command to the remote controller 202 upon receiving a charging mode setting operation.

[0055] The remote controller 202 is used to receive charging mode setting instructions sent by the external mobile device 200 and synchronize the charging mode setting instructions to the central control unit 201.

[0056] In some embodiments, the charging mode setting operation is used to set a charging control strategy, including setting the charging mode and scheduled charging information. Optionally, the charging mode setting operation includes touch operations on the user interface of the external mobile device 200 and triggering operations on shortcut controls within the UI. These shortcut controls are used to quickly switch charging modes.

[0057] Optionally, when the charging mode setting instruction indicates that the charging mode is set to the scheduled charging mode, the charging mode setting instruction may or may not include scheduled charging information.

[0058] It should be noted that when the charging control system is powered on for the first time, the charging mode is set to immediate charging mode by default and no scheduled charging information is saved. Therefore, if the charging mode setting command instructs the user to set the charging mode to scheduled charging mode, the charging mode setting command must include scheduled charging information.

[0059] In this embodiment, the charging control system can receive charging mode setting operations through the central control unit and synchronize the charging mode to the external mobile device through the remote controller. It can also receive charging mode setting instructions sent by the external mobile device after receiving the charging mode setting operation through the remote controller and synchronize the instructions to the central control unit. This achieves bidirectional synchronization between the central control unit and the remote controller, which is beneficial for information synchronization between the central control unit and the external mobile device and avoids charging control failure due to information differences between the central control unit and the external mobile device.

[0060] In some embodiments, the charging control system may further include a mode setting shortcut button, and the charging mode setting operation received by the central control unit includes a triggering operation of the mode setting shortcut button.

[0061] In some embodiments, the signal triggered by the mode setting shortcut key includes a first signal and a second signal, wherein the first signal is used to indicate that the scheduled charging mode is enabled, and the second signal is used to indicate that the scheduled charging mode is disabled. Optionally, the central control unit may have scheduled charging information configured, which may be scheduled charging information determined after receiving the charging mode setting operation, or scheduled charging information synchronized from the remote controller to the central control unit. Optionally, the central control unit may not have scheduled charging information configured.

[0062] It should be noted that the shortcut key for mode settings is unavailable if no scheduled charging information has been set.

[0063] See Figure 3 , Figure 3 This is a schematic diagram of command interaction on the central control unit side provided in an exemplary embodiment of this application. The figure shows the central control unit 301 and the remote controller 302.

[0064] The central control unit 301 is used to send a scheduled charging mode activation command to the remote controller 302 when it receives the first signal triggered by the mode setting shortcut key and when scheduled charging information is set.

[0065] In some embodiments, the charging mode setting instruction includes a scheduled charging mode activation instruction and an immediate charging mode activation instruction. Specifically, when the charging mode setting instruction is a scheduled charging mode activation instruction, the scheduled charging mode activation instruction includes scheduled charging information, which includes the charging date, charging start time, and charging duration.

[0066] Optionally, the scheduled charging information may include at least one charging date within the same time period, such as two charging dates within a week. If at least one charging date exists, the scheduled charging information includes at least one charging start time and at least one charging duration.

[0067] For example, the scheduled charging information includes a first charging date and a second charging date. The first charging date corresponds to the first charging start time and the first charging duration, and the second charging date corresponds to the second charging start time and the second charging duration.

[0068] Optionally, the scheduled charging information may also include the number of times to repeat the setting, which refers to the number of times the current scheduled charging information can be reused.

[0069] For example, if the scheduled charging information includes a charging date of Monday, a charging start time of 18:00, a first charging duration of 12 hours, and a repeat setting of 3 times, the central control unit will send instructions to the hybrid control unit from 18:00 to 6:00 on Mondays for three consecutive weeks, causing the hybrid control unit to enable charging.

[0070] The central control unit 301 is also used to display a scheduled charging information setting prompt when it receives the first signal triggered by the mode setting shortcut key and no scheduled charging information has been set.

[0071] Optionally, the scheduled charging information setting prompt can provide charging mode prompts and operation prompts. For example, the scheduled charging information setting prompt can be "Multimedia can be set to scheduled charging, no reservation this time, immediate charging." This indicates that the current charging mode is immediate charging mode, and the scheduled charging mode can be set through the central control unit 301 or external devices.

[0072] The central control unit 301 is also used to send an immediate charging mode activation command to the remote controller 302 when it receives a second signal triggered by the mode setting shortcut key.

[0073] In some embodiments, the instant charging mode activation command is used to synchronize the instant charging mode to the remote controller 302.

[0074] In this embodiment, the central control unit can quickly activate the scheduled charging mode via the mode setting shortcut button, eliminating the need to re-receive the charging mode setting operation each time and thus improving the efficiency of scheduled charging.

[0075] The following embodiments further illustrate the scenario of the central control unit synchronously charging the remote controller.

[0076] In some embodiments, the central control unit sends a charging command to the hybrid control unit through a central gateway to achieve charging control.

[0077] See Figure 4 , Figure 4 This is a schematic diagram of the command interaction on the central control unit side provided in another exemplary embodiment of this application.

[0078] The central control unit 401 is used to send a prohibition charging command to the hybrid control unit 403 through the central gateway 402 when it receives the operation to start the scheduled charging mode; to send a allow charging command to the hybrid control unit 403 through the central gateway 402 when the scheduled charging information is met at the current time; and to send a prohibition charging command to the hybrid control unit 403 through the central gateway 402 when the scheduled charging information indicates that the scheduled charging has ended.

[0079] In some embodiments, the scheduled charging information includes a charging start time and a charging duration. When the charging gun is inserted (indicating the charging gun is plugged in), the central control unit 401 sends a charging prohibition command because the scheduled charging mode does not perform immediate charging. If the current time reaches the charging start time specified in the scheduled charging information, the central control unit 401 sends a charging permission command to the hybrid control unit 403 via the central gateway 402; if the current charging duration reaches the charging duration specified in the scheduled charging information, the scheduled charging ends, and the central control unit 401 sends a charging prohibition command to the hybrid control unit 403 via the central gateway 402.

[0080] Optionally, when the current charging mode is the immediate charging mode and the battery is in the charging process, the central control unit 401 sends a prohibition charging command to the hybrid control unit 403 through the central gateway 402, instructing the hybrid control unit 403 to control the charging to be disconnected.

[0081] Optionally, the central control unit 401 is also used to update the scheduled charging information when a scheduled charging setting operation is received during the charging process; send a charging permission command to the hybrid control unit 403 through the central gateway 402 if the scheduled charging information is met at the current time; and send a charging prohibition command to the hybrid control unit 403 through the central gateway 402 if the scheduled charging information indicates that the scheduled charging has ended.

[0082] In addition, the central control unit 401 is also used to send a prohibition charging command to the hybrid control unit 403 through the central gateway 402 if the current time does not meet the reservation charging information after updating the reservation charging information; send a permission charging command to the hybrid control unit 403 through the central gateway 402 if the current time meets the reservation charging information; and send a prohibition charging command to the hybrid control unit 403 through the central gateway 402 if the reservation charging information indicates that the reservation charging has ended.

[0083] Optionally, the charging control system can enter a sleep state after the central control unit 401 sends a charging prohibition command to the hybrid control unit 403 through the central gateway 402.

[0084] The central control unit 401 is also used to send a charging permission command to the hybrid control unit 403 via the central gateway 402 when it receives a scheduled charging mode shutdown operation.

[0085] When the scheduled charging mode is off, the hybrid control unit 403 receives a charging permission command, and the charging gun status feedback from the charging and discharging power distribution indicates that the charging gun is inserted into the charging port, the hybrid control unit 403 controls the charging to start.

[0086] In some embodiments, the activation and deactivation of the scheduled charging mode include touch operations on the user interface in the central control unit 401, such as activating the scheduled charging mode by clicking the scheduled charging mode activation control in the user interface. The activation and deactivation of the scheduled charging mode also include triggering operations on the mode setting shortcut keys.

[0087] In this embodiment, when the central control unit receives an operation to enable or disable the scheduled charging mode, it sends a charging permission command or a charging prohibition command to the hybrid control unit through the central gateway. This enables the central control unit to control the charging mode or scheduled charging information in real time under different charging modes, which helps the hybrid control unit to complete charging according to the scheduled charging information, avoid charging failures, and improve charging convenience.

[0088] In some embodiments, under the scenario of a remote controller synchronizing charging control strategy to the central control unit, the remote controller sends a synchronous charging command to the central control unit, and the central control unit sends a charging command to the hybrid control unit.

[0089] When switching from immediate charging mode to scheduled charging mode, the external mobile device, upon receiving a scheduled charging mode activation command, sends a scheduled charging mode activation instruction to the remote controller. See also... Figure 5 , Figure 5 This is a schematic diagram of command interaction on the remote controller side provided in an exemplary embodiment of this application. The figure shows a central control unit 500, a remote controller 501, a central gateway 502, and a hybrid control unit 503.

[0090] The remote controller 501 is used to synchronize the scheduled charging mode activation command to the central control unit 500 when it receives the scheduled charging mode activation command sent by the external mobile device, and to send the charging prohibition command to the hybrid control unit 503 through the central gateway 502.

[0091] It should be noted that in this application, the remote controller 501 is mainly used to realize the synchronization of instructions between the external mobile device and the central control unit 500. In essence, the work of controlling the charging and power-off of the hybrid control unit 503 according to the scheduled charging information is completed by the central control unit 500. That is, the external mobile device synchronizes the scheduled charging information to the central control unit 500 through the remote controller 501 to realize scheduled charging control.

[0092] Since the hybrid control unit 503 does not need to be charged immediately in the scheduled charging mode, the remote controller 501 can send a charging prohibition command to the hybrid controller through the central gateway 502. Sending the charging prohibition command from the remote controller 501 to the hybrid control unit 503 through the central gateway 502 enables the charging process to be stopped during the immediate charging mode and switched to the scheduled charging mode, thus improving the flexibility and convenience of switching charging modes.

[0093] The central control unit 500 is used to send a charging permission command to the hybrid control unit 503 through the central gateway 502 when the current time meets the charging permission information in the charging permission mode activation command; and to send a charging prohibition command to the hybrid control unit 503 through the central gateway 502 when the charging permission information indicates that the charging permission has ended.

[0094] The scheduled charging information includes the charging start time and charging duration. When the current time reaches the charging start time specified in the scheduled charging information, the central control unit 500 sends a charging permission command to the hybrid control unit 503 via the central gateway 502; when the current charging duration reaches the charging duration specified in the scheduled charging information, the scheduled charging ends, and the central control unit 500 sends a charging prohibition command to the hybrid control unit 503 via the central gateway 502.

[0095] When the charging mode is switched from scheduled charging mode to immediate charging mode, the external mobile device sends a scheduled charging mode off command to the remote controller 501.

[0096] The remote controller 501 is also used to synchronize the scheduled charging mode shutdown command to the central control unit 500 when it receives the scheduled charging mode shutdown command sent by the external mobile device, and to send the charging permission command to the hybrid control unit 503 through the central gateway 502.

[0097] Since the hybrid control unit 503 can control immediate charging when the charging gun is inserted in the immediate charging mode, the remote controller 501 can send a charging permission command to the hybrid control unit 503 through the central gateway 502 when it receives the scheduled charging mode shutdown command.

[0098] In this embodiment, on the one hand, the remote controller synchronizes the scheduled charging mode start command and scheduled charging mode stop command to the central control unit, eliminating the need for synchronization with the central control unit and subsequent control by the central control unit, thus improving control efficiency; on the other hand, the central control unit sends the charging permission command or charging prohibition command to the hybrid control unit through the central gateway, which facilitates the reuse of the central control unit's control unit and simplifies the control logic of the remote controller.

[0099] In some embodiments, the instrument module is used to display the charging mode according to the charging mode setting instruction. When the receiving device for the charging mode setting operation is different, the transmission path of the charging mode setting instruction is different, including the following two cases:

[0100] 1. When the central control unit receives a charging mode setting operation:

[0101] The central control unit is used to synchronize the charging mode setting command to the remote controller when it receives a charging mode setting operation.

[0102] The remote controller is also used to send a charging mode setting command to the instrument module through the central gateway when it receives a charging mode setting command synchronized from the central control unit; the instrument module is used to display the charging mode based on the charging mode setting command.

[0103] Optionally, the central control unit can also send charging mode setting commands to the instrument module via the central gateway, including:

[0104] The central control unit is used to send a charging mode setting command to the instrument module through the central gateway and synchronize the charging mode setting command to the remote controller when a charging mode setting operation is received; the instrument module is used to display the charging mode based on the charging mode setting command.

[0105] Alternatively, the central control unit, upon receiving a trigger signal from the mode setting shortcut button, sends a charging mode setting command to the instrument module via the central gateway and synchronizes the charging mode setting command with the remote controller; the instrument module is used to display the charging mode based on the charging mode setting command.

[0106] 2. When the external mobile device receives a charging mode setting operation:

[0107] The remote controller is also used to receive charging mode setting instructions sent by external mobile devices and send the charging mode setting instructions to the instrument module through the central gateway; the instrument module is used to display the charging mode based on the charging mode setting instructions.

[0108] In this embodiment, the instrument module receives a charging mode setting command sent by the remote controller or central control unit through the central gateway and displays the charging mode, thereby achieving display synchronization of the instrument module.

[0109] In some embodiments, the battery management unit, charging and discharging power distribution unit, and hybrid control unit in the charging control system interact with the central control unit, remote controller, and instrument module through a central gateway.

[0110] The battery management unit is used to send at least one of the following information to the central control unit, remote controller and instrument module through the central gateway: power information, charging status and estimated full charge time.

[0111] Optionally, the charging state may include a waiting charging state, a battery heating state, a charging state, a battery cooling and charging state, and a charging end state.

[0112] In some embodiments, battery level information is used to characterize battery level, such as fully charged, depleted, or charged. The estimated full charge time can be represented as the charging end time determined based on the scheduled charging start time and charging duration, or as the remaining charging time determined by combining the current time.

[0113] The charging and discharging power distribution unit is used to send plug status information to the central control unit, remote controller, and instrument module through the central gateway.

[0114] In some embodiments, the charging gun insertion status information is used to characterize the insertion status of the charging gun, including the charging gun insertion status and the charging gun not inserted status.

[0115] The hybrid control unit is used to send charging fault information to the central control unit, remote controller, and instrument module via the central gateway in the event of a charging fault.

[0116] Optionally, the charging control system may also include a charging gun. The battery management unit can send charging status information to the charging gun, the charge / discharge distribution unit can send insertion status information to the charging gun, and the hybrid control unit can send charging fault information to the charging gun, causing the charging gun indicator light to display accordingly. For example, a yellow light indicates a waiting charging state, a white light indicates the charging gun is not inserted, a red light indicates a charging fault indicating charging failure, a green light indicates charging is complete, a flashing green light indicates charging is underway, and the light turns off 30 seconds after power is off.

[0117] In this embodiment, the battery management unit, the charging and discharging power distribution unit, and the hybrid control unit send information to the central control unit, external mobile devices, and the instrument module through the central gateway, so that the central control unit, external mobile devices, and the instrument module can maintain display synchronization.

[0118] See Figure 6 , Figure 6 This diagram illustrates an implementation of the charging control process of a charging control system provided in an exemplary embodiment of this application. The charging control process is implemented when the central control unit receives a charging mode setting operation. The charging control system includes: a central control unit 601, a remote controller 602, a central gateway 603, an instrument module 604, a charging / discharging power distribution unit 605, a hybrid control unit 606, and a battery management unit 607.

[0119] The central control unit 601 is used to synchronize the charging mode setting command IHU_ChargeModeSet to the remote controller 602 when it receives a charging mode setting operation. If the charging mode setting command IHU_ChargeModeSet is the reservation charging mode start command IHU_ChargeModeSet = Reservation Charge, the central control unit 601 is used to synchronize the reservation charging information to the remote controller 602.

[0120] The scheduled charging information includes the first charging date (IHU_ChargeTimeWeekSet1), the hour of the first charging start time (IHU_TimeToStartChargeHourSet1), the minute of the first charging start time (IHU_TimeToStartChargeMinuteSet1), and the first charging duration (IHU_ChargeTimeHourSet1). The scheduled charging information also includes the second charging date (IHU_ChargeTimeWeekSet2), the hour of the second charging start time (IHU_TimeToStartChargeHourSet2), the minute of the second charging start time (IHU_TimeToStartChargeMinuteSet2), and the second charging duration (IHU_ChargeTimeHourSet2). Optionally, the first and second charging dates can be charging dates within the same week.

[0121] The charging mode setting instructions include the immediate charging mode activation instruction IHU_ChargeModeSet=Immediate Charge and the reserved charging mode activation instruction IHU_ChargeModeSet=Reservation Charge.

[0122] The remote controller 602 is used to receive and send charging mode setting instructions and scheduled charging information to the external mobile device synchronization control unit 601.

[0123] The central control unit 601 is also used to send a charging command IHU_ChargeAllow to the hybrid control unit 606 through the central gateway 603, including the charging allow command IHU_ChargeAllow=Allow and the charging disallow command IHU_ChargeAllow=Not Allow.

[0124] In the immediate charging mode, the central control unit 601 sends a charging permission command IHU_ChargeAllow=Allow to the hybrid control unit 606 through the central gateway 603.

[0125] In the scheduled charging mode, the central control unit 601, based on the scheduled charging information, first sends a charging prohibition command IHU_ChargeAllow=Not Allow to the hybrid control unit 606 through the central gateway 603. When the charging start time is reached, it sends a charging allow command IHU_ChargeAllow=Allow to the hybrid control unit 606. When charging ends, it sends a charging allow command IHU_ChargeAllow=Not Allow to the hybrid control unit 606.

[0126] The central control unit 601 is also used to receive and display the following information, including: plug-in status information OBC_CC_ConnectSts sent by the charging and discharging power distribution unit 605 through the central gateway 603; charging fault information HCU_ChargeFault sent by the hybrid control unit 606 through the central gateway 603; and power information BMSH_SOCDisp, charging status BMSH_PackChargingThermalSt, and estimated full charge time BMSH_LeftChargeTime sent by the battery management unit 607.

[0127] The central control unit 601 is also used to send the charging mode setting command IHU_ChargeModeSet to the instrument module 604 through the central gateway 603.

[0128] The remote controller 602 is also used to receive and synchronize the plug status information OBC_CC_ConnectSts sent by the charging and discharging power distribution unit 605 through the central gateway 603 to the external mobile device, receive and synchronize the charging fault information HCU_ChargeFault sent by the hybrid control unit 606 through the central gateway 603 to the external mobile device, and receive and synchronize the power information BMSH_SOCDisp, charging status BMSH_PackChargingThermalSt, and estimated full charge time BMSH_LeftChargeTime sent by the battery management unit 607 to the external mobile device.

[0129] The instrument module 604 is used to receive and display the following information, including: plug-in status information OBC_CC_ConnectSts sent by the charging and discharging power distribution unit 605 through the central gateway 603; charging fault information HCU_ChargeFault sent by the hybrid control unit 606 through the central gateway 603; power information BMSH_SOCDisp, charging status BMSH_PackChargingThermalSt, and estimated full charge time BMSH_LeftChargeTime sent by the battery management unit 607; and charging mode setting command IHU_ChargeModeSet sent by the central control unit 601.

[0130] Optionally, when the charging gun is inserted into the charging port and the vehicle is powered off, the instrument module 604 will turn off after 30 seconds.

[0131] For example, when BMSH_LeftChargeTime = 1, the central control unit 601 and the instrument module 604 display that the battery is about to be fully charged. When BMSH_LeftChargeTime = 0, the central control unit 601 and the instrument module 604 do not display the estimated charging time. When the value of BMSH_LeftChargeTime is neither zero nor one, the central control unit 601 and the instrument module 604 display the estimated charging time. For example, BMS H_LeftChargeTime = 1022 represents "estimated remaining time for charging: 10 hours and 22 minutes".

[0132] For example, when OBC_CC_ConnectSts=1, the central control unit 601 and the instrument module 604 display that the charging gun is inserted, and when OBC_CC_ConnectSts=0, the central control unit 601 and the instrument module 604 display that the charger is not inserted.

[0133] It should be noted that even when the charging gun is not inserted, the central control unit 601 can still receive charging mode setting operations or charge mode settings, as well as store scheduled charging information.

[0134] For example, when BMSH_PackChargingThermalSt = None (waiting to charge), Heating (battery heating state), or Charging Finish (charging completed state), the central control unit 601 and the instrument module 604 display "not charging". When BMSH_PackChargingThermalSt = CoolingAndCharging (battery cooling and charging state) or Charging (charging in progress), the central control unit 601 and the instrument module 604 display "charging in progress".

[0135] In this embodiment, upon receiving an operation to enable or disable the scheduled charging mode, the central control unit sends a charging command to the hybrid control unit via the central gateway, controlling the hybrid control unit to start or disable charging. This facilitates the hybrid control unit completing charging according to the scheduled charging information, avoiding charging failures. The battery management unit, charging / discharging power distribution unit, and hybrid control unit send information to the central control unit, external mobile devices, and instrument module via the central gateway, ensuring that the central control unit, external mobile devices, and instrument module maintain synchronized displays.

[0136] See Figure 7 , Figure 7 A schematic diagram illustrating an implementation of the charging control process of a charging control system provided in another exemplary embodiment of this application is shown. This charging control process is implemented when the central control unit receives a charging mode setting operation. The charging control system includes: a central control unit 701, a remote controller 702, a central gateway 703, an instrument module 704, a charging / discharging power distribution unit 705, a hybrid control unit 706, and a battery management unit 707.

[0137] The remote controller 702 is used to synchronize the charging mode setting command TBOX_ChargeModeSet to the central control unit 701 when it receives the charging mode setting command sent by the external mobile device, and to synchronize the reservation charging information to the central control unit 701 when it receives the reservation charging mode start command TBOX_ChargeModeSet=Reservation Charge sent by the external mobile device.

[0138] The scheduled charging information includes the first charging date (TBOX_ChargeTimeWeekSet1), the hour of the first charging start time (TBOX_TimeToStartChargeHourSet1), the minute of the first charging start time (TBOX_TimeToStartChargeMinuteSet1), and the first charging duration (TBOX_ChargeTimeHourSet1). The scheduled charging information also includes the second charging date (TBOX_ChargeTimeWeekSet2), the hour of the second charging start time (TBOX_TimeToStartChargeHourSet2), the minute of the second charging start time (TBOX_TimeToStartChargeMinuteSet2), and the second charging duration (TBOX_ChargeTimeHourSet2). Optionally, the first and second charging dates can be charging dates within the same week.

[0139] The charging mode setting instructions include the immediate charging mode activation instruction TBOX_ChargeModeSet = Immediate Charge and the scheduled charging mode activation instruction TBOX_ChargeModeSet = ReservationCharge.

[0140] In the instant charging mode, the remote controller 702 is also used to send a charging permission command TBOX_ChargeAllow=Allow to the hybrid control unit 706 via the central gateway 703 when it receives an instant charging mode activation command sent by an external mobile device.

[0141] In the scheduled charging mode, the remote controller 702 is also used to send a charging prohibition command TBOX_ChargeAllow=Not Allow to the hybrid control unit 706 via the central gateway 703 upon receiving a scheduled charging mode activation command from an external mobile device. The central control unit 701 is used to send a charging allow command IHU_ChargeAllow=Allow to the hybrid control unit 706 upon reaching the charging start time, and to send a charging allow command IHU_ChargeAllow=Not Allow to the hybrid control unit 706 upon completion of charging.

[0142] The remote controller 702 is also used to receive and synchronize the following information with external mobile devices and the central control unit 701, including: plug-in status information OBC_CC_ConnectSts sent by the charging and discharging power distribution unit 705 through the central gateway 703, charging fault information HCU_ChargeFault sent by the hybrid control unit 706 through the central gateway 703, and power information BMSH_SOCDisp, charging status BMSH_PackChargingThermalSt, and estimated full charge time BMSH_LeftChargeTime sent by the battery management unit 707.

[0143] The remote controller 702 is also used to send the charging mode setting command TBOX_ChargeModeSet to the instrument module 704 via the central gateway 703.

[0144] The central control unit 701 is also used to receive and display the plug-in status information OBC_CC_ConnectSts sent by the charging and discharging power distribution unit 705 through the central gateway 703, the charging fault information HCU_ChargeFault sent by the hybrid control unit 706 through the central gateway 703, the power information BMSH_SOCDisp, the charging status BMSH_PackChargingThermalSt, and the estimated full charge time BMSH_LeftChargeTime sent by the battery management unit 707, and the charging mode setting instruction TBOX_ChargeModeSet sent by the remote controller 702.

[0145] The instrument module 704 is used to receive and display the plug status information OBC_CC_ConnectSts sent by the charging and discharging power distribution unit 705 through the central gateway 703, the charging fault information HCU_ChargeFault sent by the hybrid control unit 706 through the central gateway 703, the power information BMSH_SOCDisp, the charging status BMSH_PackChargingThermalSt, and the estimated full charge time BMSH_LeftChargeTime sent by the battery management unit 707, and the charging mode setting command TBOX_ChargeModeSet sent by the remote controller 702.

[0146] Optionally, when the charging gun is inserted into the charging port and the vehicle is powered off, the instrument module 704 will turn off after 30 seconds.

[0147] In this embodiment, on the one hand, the remote controller synchronizes the scheduled charging mode activation and deactivation commands to the central control unit, eliminating the need for the central control unit to control the system after synchronization, thus improving control efficiency. On the other hand, the central control unit sends charging permission or charging prohibition commands to the hybrid control unit via the central gateway, which facilitates the reuse of the central control unit's control unit and simplifies the control logic of the remote controller. Furthermore, the battery management unit, charging / discharging power distribution unit, and hybrid control unit send information to the central control unit, external mobile devices, and instrument module via the central gateway, enabling these components to maintain display synchronization.
