[0036] The embodiments of this application are described in detail below. Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this application, and should not be construed as limiting this application.

[0037] Figure 1 This is a flowchart illustrating a charging control method according to an exemplary embodiment of this application, such as... Figure 1 As shown, the charging control method includes the following steps:

[0038] S101 determines the charging start time and the heat preservation start time based on the user's travel time.

[0039] Specifically, the charging control method of this application embodiment can be executed by the charging control device provided in this application embodiment. The charging control device can be set in the vehicle control system to provide charging control services and heat preservation control services for the vehicle.

[0040] The system can determine the start time for charging the vehicle based on the user's travel time and perform subsequent processing. The user's travel time is the start time of the user's next vehicle use, which can be set by the user. If the user does not set a travel time, the default travel time will be used, or the possible travel time will be estimated based on the user's historical vehicle use information. This application does not impose too many restrictions on this.

[0041] The start time for heat preservation of the battery can be determined based on the user's travel time, and subsequent processing can be carried out. The start time for heat preservation can be determined at the same time as the start time of charging, or it can be determined at the start of charging, during charging, at the end of charging, or after charging. This application does not impose too many restrictions on this.

[0042] It's important to note that batteries require a specific temperature range to function properly. Typically, battery performance degrades in low-temperature environments (such as winter), reducing discharge capacity and impacting overall battery performance. Maintaining a suitable battery temperature when the vehicle is in a cold environment not only ensures normal vehicle operation but also saves energy and extends driving range. Therefore, after charging, the battery needs to be kept at a suitable temperature to ensure optimal performance when the vehicle is used again, guaranteeing the smooth operation of the entire vehicle system. This also improves battery safety and extends battery life. Furthermore, since temperature maintenance consumes additional energy, precisely selecting the start time based on the user's travel schedule allows for controlled temperature maintenance between charging completion and travel time, minimizing energy consumption and reducing user operating costs.

[0043] S102, when the current time reaches or exceeds the charging start time, start battery charging.

[0044] Specifically, the current time is compared with the charging start time determined in step S101. If the current time reaches or exceeds the charging start time (i.e., the current time is greater than or equal to the charging start time), charging of the battery begins immediately. It should be noted that the current time is the current time acquired and recorded by the vehicle control system, and this application does not impose excessive limitations on it.

[0045] S103 activates battery insulation when the current time reaches or exceeds the insulation start time.

[0046] Specifically, the current time is compared with the heat preservation start time determined in step S101. If the current time reaches or exceeds the heat preservation start time, i.e., the current time is greater than or equal to the heat preservation start time, the heat preservation of the battery is started immediately.

[0047] S104, when the departure time is reached at the current time, the battery insulation ends.

[0048] Specifically, during the battery insulation process, the current time is compared with the user's travel time. When the current time equals the travel time, the battery insulation process is completed and is no longer required. Otherwise, the battery insulation process continues until the travel time is reached.

[0049] In this embodiment, the charging start time and the heat preservation start time are determined based on the user's travel time. Battery charging begins when the current time reaches or exceeds the charging start time, and battery heat preservation begins when the current time reaches or exceeds the heat preservation start time. Battery heat preservation ends when the current time reaches the travel time. Therefore, by determining the start times of charging and heat preservation based on the user's travel time, the vehicle battery can be charged while consuming less electricity to achieve the desired battery temperature during the user's travel, ensuring the normal operation of the entire vehicle system, increasing the vehicle's range, and also improving battery safety and lifespan.

[0050] Figure 2 This is a schematic flowchart of a charging control method according to a second embodiment of this application.

[0051] like Figure 2 As shown, based on the above embodiments, the charging control method of this application embodiment may specifically include the following steps:

[0052] S201, the system detected that the reservation travel function is enabled and that the charging gun is connected to the vehicle.

[0053] Specifically, users can activate the smart reservation travel function through the vehicle's central control system or an app (application software). When the reservation travel function is detected as activated and the charging gun is electrically connected to the vehicle's charging port, the charging control method of this application embodiment is executed on the vehicle. When the reservation travel function is detected as not activated, the charging gun is not connected to the vehicle's charging port, or the charging gun is not electrically connected to the vehicle's charging port due to malfunction or other reasons, the charging control method of this application embodiment is not executed on the vehicle. The smart reservation travel function allows users to pre-set the next time they need to use the vehicle. This ensures that the vehicle is fully charged and the battery is at a suitable temperature before the next use, thus improving the vehicle's driving range and battery safety.

[0054] It should be noted that the connection method of the charging gun can be determined based on the vehicle's CAN (Controller Area Network) signal to determine whether the charging gun is electrically connected to the vehicle. If the connection method of the charging gun is fully connected, it means that the charging gun is electrically connected to the vehicle.

[0055] Step S101 in the above embodiment, "determining the charging start time and the heat preservation start time based on the user's travel time," may specifically include the following step S202:

[0056] S202 determines the charging start time and the heat preservation start time based on the charging mode and travel time.

[0057] Specifically, the charging mode may include, but is not limited to, charging priority mode, equalization charging mode, and energy-saving priority charging mode. The charging mode can be selected by the user. At this time, the charging mode is the mode selected by the user. If the user does not make a selection, the charging mode defaults to one of the modes, such as charging priority mode. The charging start time and the heat preservation start time can be further determined according to the user's selected or default charging mode and the user's travel time. For details, please refer to step S101 in the above embodiment.

[0058] S203: When the current time reaches or exceeds the charging start time, start battery charging.

[0059] Specifically, step S203 in this embodiment is the same as step S102 in the above embodiment, and will not be repeated here.

[0060] S204 controls the vehicle to enter a sleep state before the charging start time has arrived at the current time.

[0061] Specifically, the current time is compared with the charging start time determined in step S202. If the current time has not reached the charging start time, i.e., the current time is less than the charging start time, the vehicle is controlled to enter a sleep state and wait for the charging start time to arrive in order to save power.

[0062] S205, when the current time reaches the charging start time, controls the vehicle to exit the hibernation state and starts battery charging.

[0063] Specifically, the current time is compared with the charging start time determined in step S202. When the current time reaches the charging start time, i.e., the current time is equal to the charging start time, the vehicle is controlled to exit the hibernation state, i.e., the vehicle is woken up, and the battery is started to charge.

[0064] S206, the start time of insulation is re-determined after the travel time is changed.

[0065] Specifically, after the current time reaches or exceeds the charging start time and battery charging is started (e.g., during charging, at the end of charging, or after charging is completed), if the user's travel time changes, the insulation start time will be re-determined based on the changed travel time to obtain a new insulation start time.

[0066] S207 activates battery insulation when the current time reaches or exceeds the insulation start time.

[0067] Specifically, step S207 in this embodiment is the same as step S103 in the above embodiment, and will not be repeated here.

[0068] S208 controls the vehicle to enter a sleep state before the start time of heat preservation.

[0069] Specifically, the current time is compared with the heat preservation start time determined in step S202. If the current time has not reached the heat preservation start time, i.e., the current time is less than the heat preservation start time, the vehicle is controlled to enter a sleep state and wait for the heat preservation start time to arrive in order to save power.

[0070] S209, when the current time reaches the start time of heat preservation, controls the vehicle to exit the hibernation state and starts the battery heat preservation.

[0071] Specifically, the current time is compared with the heat preservation start time determined in step S202. When the current time reaches the charging start time, that is, when the current time is equal to the heat preservation start time, the vehicle is controlled to exit the hibernation state, that is, the vehicle is woken up, and the battery is kept warm.

[0072] S210 ends battery insulation when the departure time is reached at the current time.

[0073] Specifically, step S210 in this embodiment is the same as step S104 in the above embodiment, and will not be repeated here.

[0074] Furthermore, when the charging mode is the charging priority mode, the step S202 in the above embodiment, "determine the charging start time according to the charging mode and travel time", may specifically include the following steps: determining the current time as the charging start time.

[0075] Specifically, when the charging mode is the charging priority mode, the charging start time is the current time, that is, when the reservation travel function is detected to be enabled and the charging gun is electrically connected to the vehicle charging interface, the battery charging will start immediately.

[0076] Furthermore, such as Figure 3 As shown, when the charging mode is equalization charging mode, step S202 in the above embodiment, "determining the charging start time according to the charging mode and travel time", may specifically include the following steps S301-S305:

[0077] S301 predicts the first charging time, the first heat preservation time, and the first cooling time.

[0078] Specifically, the charging, heat preservation, and cooling durations can be predicted based on the current state of the vehicle battery, ambient temperature, and travel time, thus obtaining the first charging duration, the first heat preservation duration, and the first cooling duration. The current state of the battery can specifically include the battery's current SOH (State of Health), current SOC (State of Charge), battery temperature, current available energy, and current battery health. This application does not impose excessive limitations on the specific prediction methods for the charging, heat preservation, and cooling durations.

[0079] S302, obtain the duration of the local power grid trough.

[0080] Specifically, the system determines whether there is a trough in the local AC charging grid. If a trough exists, it reads the trough data and obtains the corresponding trough duration. This application does not impose excessive restrictions on the specific method for obtaining the grid trough duration.

[0081] S303, if the trough duration is equal to or greater than the first charging duration, then the time corresponding to the difference between the end time of the trough and the first charging duration is determined as the charging start time.

[0082] Specifically, the valley duration of the local power grid obtained in step S302 is compared with the first charging duration predicted in step S301. If the valley duration is equal to or greater than the first charging duration, the end time of the valley is subtracted from the first charging duration. The time corresponding to the difference between the two is the charging start time, i.e., charging start time = valley end time - first charging duration.

[0083] S304, if the trough duration is less than the first charging duration, then the trough start time is determined as the charging start time.

[0084] Specifically, the valley duration of the local power grid valley obtained in step S302 is compared with the first charging duration predicted in step S301. If the valley duration is less than the first charging duration, the charging start time is the valley start time, that is, the charging start time = valley start time.

[0085] S305, if there is no trough in the local power grid, calculate the first sum of the first heat preservation time, the first cooling time, and the first charging time, and determine the time corresponding to the difference between the travel time and the first sum as the charging start time.

[0086] Specifically, if there is no trough in the local AC charging grid, the first charging time, the first heat preservation time, and the first cooling time predicted in step S301 are added together to obtain the first sum. The user's travel time is then subtracted from this sum. The time corresponding to the difference is the charging start time, i.e., charging start time = travel time - first charging time - first heat preservation time - first cooling time.

[0087] Furthermore, such as Figure 4 As shown, when the charging mode is the energy-saving priority charging mode, the step S202 in the above embodiment, "determining the charging start time according to the charging mode and travel time", may specifically include the following steps S401-S403:

[0088] S401, predicts the second charging time and the second heat preservation time.

[0089] Specifically, the charging time and heat preservation time can be predicted based on the current state of the battery, the ambient temperature, and the user's travel time, thereby obtaining the second charging time and the second heat preservation time. For details, please refer to step S301 in the above embodiment.

[0090] S402, calculate the second sum of the second heat preservation time and the second charging time.

[0091] Specifically, based on the second charging time and the second heat preservation time predicted in step S401, the two are added together to obtain a second sum.

[0092] S403, the time corresponding to the difference between the departure time and the second sum is determined as the charging start time.

[0093] Specifically, the user's travel time is subtracted from the second sum of the second heat preservation time and the second charging time calculated in step S402. The time corresponding to the difference is the charging start time, that is, charging start time = travel time - second heat preservation time and second charging time.

[0094] Furthermore, such as Figure 5 As shown, when the charging mode is charging priority mode or equalization charging mode, the step S202 in the above embodiment, "determining the start time of heat preservation according to the charging mode and travel time", may specifically include the following steps S501-S502:

[0095] S501, predicted third insulation duration.

[0096] Specifically, the heat preservation time can be predicted based on the battery status at the time of charging completion, the ambient temperature, and the user's travel time, thus obtaining the third heat preservation time.

[0097] S502, the time corresponding to the difference between the departure time and the third insulation duration is determined as the insulation start time.

[0098] Specifically, the user's travel time is subtracted from the third insulation duration predicted in step S501, and the time corresponding to the difference is the insulation start time, i.e., insulation start time = travel time - third insulation duration.

[0099] Furthermore, when the charging mode is the energy-saving priority charging mode, the step S202 in the above embodiment, "determine the start time of heat preservation according to the charging mode and travel time", may specifically include the following steps: determining the current time as the start time of heat preservation.

[0100] Specifically, when the charging mode is the energy-saving priority charging mode, the start time of heat preservation is the current time, that is, the heat preservation of the battery begins immediately after the battery is fully charged.

[0101] In this embodiment, after detecting that the scheduled travel function is activated and the charging gun is connected to the vehicle, the corresponding charging and heat preservation start times are determined according to different charging modes and travel times. The current time is compared with the charging and heat preservation start times respectively. Depending on whether the current time has reached the corresponding start time, the vehicle is put into sleep mode or woken up to charge and preserve the battery until the current time reaches the travel time. Therefore, by determining the charging and heat preservation start times based on the user's travel time, the vehicle battery can be charged and kept warm with less power consumption to achieve the user's desired battery temperature during travel, ensuring the normal operation of the entire vehicle system, increasing the vehicle's range, and improving battery safety and lifespan. Furthermore, determining the charging and heat preservation start times corresponding to different charging modes allows for appropriate vehicle processing, meeting the user's charging needs in different scenarios, increasing the flexibility and efficiency of vehicle charging and heat preservation.
