[0040] It should be noted that, in the absence of conflict, the embodiments of the present invention and the features of the embodiments may be combined with each other.

[0041] In addition, the “rate charging” mentioned in the embodiments of the present invention refers to charging with preferential charging prices.

[0042] The present invention will be described in detail below with reference to the accompanying drawings and in conjunction with embodiments.

[0043] Figure 1 FIG. 1 is a flow chart of a vehicle scheduled charging control method according to an embodiment of the present invention, wherein Figure 2 is a schematic diagram of the structure of a vehicle charging system according to an embodiment of the present invention, wherein the vehicle scheduled charging control method is performed for the vehicle charging system. Figure 2 The vehicle charging system includes a vehicle gateway device (taking GW (Gateway) as an example), a mobile terminal, a power chassis domain controller, a background server (taking a telematics service provider (TSP) as an example), a vehicle terminal (taking T-box as an example), a vehicle head unit (HUT), a vehicle controller (HCU), an on-board charger (On Board of Charge), a DC-DC converter (DCDC), a battery management system (BMS), a power battery pack, a storage battery (e.g., 12V), and a charging gun. Among them, the mobile terminal is, for example, a smart phone, and the TSP and the mobile terminal and the T-box all exchange information through, for example, 2G / 3G / 4G / 5G signals, and the various components in the vehicle, such as HUT, HCU, BMS, and power chassis domain controllers, exchange information through GW and use the CAN bus in the vehicle. In addition, the charging gun charges the power battery pack through OBC. The high voltage electricity output by the power battery pack can be converted into low voltage electricity by DCDC to charge the battery. BMS is used to manage the charging and discharging of the power battery pack.

[0044] exist Figure 2 Based on Figure 1 The vehicle scheduled charging control method is applied to an in-vehicle computing unit and may include the following steps S100 and S200:

[0045] Step S100, determining the scheduled charging waiting time according to charging related information, charging gun connection time and estimated charging time.

[0046] Step S200, in response to determining the scheduled charging waiting time, starting to count, and when the count reaches the scheduled charging waiting time, sending a charging permission signal to the vehicle control unit of the vehicle so that the vehicle control unit controls the vehicle to charge.

[0047] Through step S100 and step S200, it is easy to know that in the embodiment of the present invention, the calculation of the waiting time for scheduled charging and the timing of scheduled charging are completed by the in-vehicle computing unit, and the T-box is no longer responsible for the calculation and timing functions, thereby greatly reducing the work tasks and information processing volume of the T-box, optimizing the weight of the charging function undertaken by the T-box, and avoiding the problem of frequent failures caused by the excessive weight of the charging function undertaken by the T-box. Accordingly, the vehicle scheduled charging control method of the embodiment of the present invention is conducive to ensuring the normal operation of the scheduled charging function, optimizing the customer experience, and reducing the occurrence of after-sales problems.

[0048] Preferably, the in-vehicle computing unit can be any one of the vehicle's gateway device, on-board host, battery management system and power chassis domain controller. However, it should be noted that the gateway device, on-board host, battery management system and power chassis domain controller are components of the vehicle itself. In addition to being used as in-vehicle computing units to implement the vehicle reservation charging control method of the embodiment of the present invention, they can also implement other necessary steps in the vehicle reservation charging process based on their respective basic functions. In addition, the in-vehicle computing unit can also be other controllers or components in the vehicle that can realize calculation and timing functions, and the embodiment of the present invention does not limit this.

[0049] The following uses a gateway device, a vehicle host, a battery management system, and a power chassis domain controller as examples to describe more implementation details of the vehicle scheduled charging control method of an embodiment of the present invention involved in step S100 and step S200.

[0050] Example 1: A vehicle scheduled charging control method applied to a gateway device (GW).

[0051] In this example 1, for step S100, the charging related information includes basic charging parameters and vehicle use time, wherein the basic charging parameters include charging mode (scheduled charging or immediate charging), charging SOC limit (e.g. 50% to 100%), charging current setting (e.g. 8A, 10A, 13A, 32A), etc. It is understandable that the vehicle scheduled charging control method of the embodiment of the present invention is of course for the scheduled charging mode.

[0052] It should be noted that the definitions of information and parameters involved in the embodiments of the present invention are consistent in various examples, so the same information and parameters will not be repeatedly described in other examples below.

[0053] Among them, setting the charging-related information can be understood as making an appointment for charging settings, and in a preferred embodiment, the step of making an appointment for charging settings can be performed before step S100, specifically including: receiving the charging-related information set by the mobile terminal and sent in sequence through the vehicle's backend server and the on-board terminal, and forwarding the charging-related information to the on-board host for synchronous update and display; and / or receiving the charging-related information set and sent by the on-board host, and forwarding the charging-related information to the backend server or the mobile terminal for synchronous update and display.

[0054] It is easy to know that the preferred embodiment provides two methods of setting up scheduled charging in the mobile terminal and setting up scheduled charging in the HUT. The following will specifically introduce these two methods in conjunction with FIG. 3( a ) and FIG. 3( b ).

[0055] 1. Make a reservation for charging settings on the mobile terminal.

[0056] FIG3( a ) is a flow chart of charging reservation settings in a mobile terminal in Example 1 of an embodiment of the present invention, wherein the mobile terminal takes a smart phone as an example, and the related charging reservation settings are mainly completed by an APP (Application) in the smart phone.

[0057] In conjunction with FIG. 3( a ), the example process of setting a scheduled charging in a mobile terminal mainly includes the following steps:

[0058] Step S301, the APP sets and sends the charging related information to the GW through the TSP.

[0059] The charging related information includes, for example, the car usage time Phone_Week_Hour_Min set by the mobile phone, the rate charging start time Phone_Rate_Star_Hour_Min set by the mobile phone, and the rate charging end time Phone_Rate_End_Hour_Min set by the mobile phone. After the APP sets the charging related information, it sends it to the TSP, and the TSP then sends the charging related information to the GW through the T-box.

[0060] Step S303, the GW stores and performs charging settings based on the charging related information, and sends a feedback signal after performing the charging settings to the TSP and the HUT, so that the two are updated and displayed synchronously.

[0061] Among them, the feedback signal includes, for example: the vehicle usage time GW_Week_Hour_Min determined by GW, the rate charging start time GW_Rate_Star_Hour_Min determined by GW, and the rate charging end time GW_Rate_End_Hour_Min determined by GW. GW can forward the feedback signal to TSP through T-box, and TSP will feedback the appointment setting to APP after judgment. For example, if TSP receives the feedback signal within 10s (definable value (To Be Determination, TBD)) and the coding value of the corresponding signal is consistent, it indicates that the appointment charging setting is successful and sent to APP, so that APP and HUT are displayed synchronously. Otherwise, the setting fails, and APP will display "Setting failed, please try again".

[0062] 2. Set up a scheduled charging session in HUT.

[0063] FIG3( b ) is a schematic diagram of a flow chart of setting a scheduled charging in a vehicle head unit (HUT) in Example 1 of an embodiment of the present invention, wherein the meanings of the relevant signals and abbreviations are the same as those in FIG3( a ) and are not described again herein.

[0064] In conjunction with FIG. 3( b ), the example process of setting up scheduled charging in the HUT mainly includes the following steps:

[0065] Step S302: The HUT sets the charging related information and sends it to the GW.

[0066] The charging-related information set by the HUT is, for example: the vehicle use time HUT_Week_Hour_Min determined by the HUT, the rate charging start time HUT_Rate_Star_Hour_Min determined by the HUT, and the rate charging end time HUT_Rate_End_Hour_Min determined by the HUT.

[0067] Step S304, the GW stores and performs charging settings based on the charging related information, and sends a feedback signal after performing the charging settings to the TSP and the HUT, so that the two are updated and displayed synchronously.

[0068] The example process of step S304 may refer to the above-mentioned step S303, which will not be described in detail here.

[0069] Therefore, combining the above two points, it can be known that in the embodiment of the present invention, it is possible to perform scheduled charging settings through a smart phone and / or HUT, which can bring two advantages: first, compared with the solution of using a T-box to perform scheduled charging settings, it avoids the failure of the T-box due to extreme low temperature (for example, below -20 degrees Celsius) making it impossible for customers to successfully perform scheduled charging settings; second, when the network between the T-box and the TSP is abnormal due to geographical influences (underground parking lots, closed garages, railways, etc.), the scheduled charging settings can still be completed through the HUT and transmitted to the GW.

[0070] Continuing back to step S100, the scheduled charging waiting time is the time starting from the charging gun connection time, more specifically, it refers to the time between the charging gun connection time and the scheduled charging start time. For example, the charging gun connection time is 9 o'clock in the morning, and the scheduled charging start time is 12 o'clock thereafter, then the scheduled charging waiting time represents the 3 hours between 9 o'clock and 12 o'clock. In addition, the charging gun connection time can be detected by OBC, and OBC transmits the charging gun connection time to GW. In addition, it should be noted that the "scheduled charging start time" quoted here is intended to clarify the starting and ending points of the scheduled charging waiting time, and its value is not pre-acquired or measured, but can only be further determined after the scheduled charging waiting time is determined first.

[0071] On this basis, considering that there are two situations in practice: charging without a rate and charging with a rate, the following specifically introduces the process of determining the scheduled charging waiting time according to charging-related information, charging gun connection time and expected charging time implemented in step S100 with examples.

[0072] In this example, the relevant parameters are defined as follows:

[0073] 1) Define the rate charging start time as t f1 , rate charging termination time is t f2 , the time of using the vehicle is t3. Among them, t f1 ,t f2 It is defined for the case of rate charging, in which case, t f1 ,t f2 It can be included in the above-mentioned charging related information.

[0074] 2) Define the estimated charging time as Δt. It should be noted that in the embodiment of the present invention, the BMS performs a power analysis on the power battery pack in real time to obtain Δt, and transmits the value of Δt to the TSP through the T-box.

[0075] 3) Define the waiting time for scheduled charging as Δt start , and the charging gun connection time is t.

[0076] Combined with these parameter definitions, the GW calculation strategies for the two scenarios of free-rate charging and rate-based charging are introduced below with reference to the accompanying drawings.

[0077] I. Free-rate charging scenario

[0078] In this scenario, first, the time point obtained by subtracting the estimated charging duration Δt from the vehicle usage time t3 is calculated as the initial charging start time, that is, the initial charging start time is t3 - Δt, which indicates that charging must start before this initial charging start time at the latest. Otherwise, according to the estimated charging duration Δt, the requirement of the vehicle usage time t3 cannot be met. Then, according to the relationship between the charging gun connection time t and the interval [t3 - Δt, t3], the reserved charging waiting duration Δt is determined. start , which specifically includes Figure 4(a)-Figure 4(d) the four time relationships shown.

[0079] 1) Fig. 4(a) is a schematic diagram of the time relationship in Example 1 of the present invention, where the charging gun connection time is less than the initial charging start time.

[0080] As shown in Fig. 4(a), that is, t < t3 - Δt. At this time, the charging gun has been connected before the initial charging start time, so reserved charging can be executed to determine Δt. start = t3 - Δt - t.

[0081] For example, if t is 13:00 and t3 - Δt is 14:00, then Δt start is 1h, so it can be reserved to charge within 1 hour after 13:00, which can meet the requirement of the vehicle usage time t3.

[0082] 2) Fig. 4(b) is a schematic diagram of the time relationship in Example 1 of the present invention, where the charging gun connection time is greater than or equal to the initial charging start time and less than the vehicle usage time.

[0083] As shown in Fig. 4(b), that is, t3 - Δt ≤ t < t3. At this time, the charging gun has not been connected before the initial charging start time, and it is difficult to meet the requirement of the vehicle usage time t3. Therefore, immediate charging needs to be executed to determine Δt. start = 0.

[0084] For example, if t3 - Δt is 14:00, t3 is 16:00, and t is 15:00, then Δt start is 0, so charging is carried out immediately. When the vehicle usage time of 16:00 arrives, although the 2-hour estimated charging duration cannot be achieved, it can still be charged for 1 hour to ensure the normal operation of the vehicle.

[0085] 3) Fig. 4(c) is a schematic diagram of the time relationship in Example 1 of the present invention, where the charging gun connection time is greater than the vehicle usage time.

[0086] As shown in Figure 4(c), i.e., t≥t3, at this time, the vehicle use time t3 has arrived but the charging gun has not been connected yet, so there is no need to consider the scheduled charging for this vehicle use, but the next vehicle use time should be considered to determine the scheduled charging waiting time Δt for the next vehicle use. start Among them, the waiting time for charging scheduled for the next use of the car is Δt start Also refer to Figure 4(a)-Figure 4(d) It will not be described in detail here.

[0087] 4) FIG. 4( d ) is a schematic diagram of the time relationship in which the initial charging time is greater than or equal to the vehicle use time in Example 1 of an embodiment of the present invention.

[0088] As shown in Figure 4(d), t3≥t3-Δt, which is obviously unconventional and invalid, so there is no need to reserve the charging waiting time Δt. start It should be noted that the judgment corresponding to FIG4(d) is the same as the calculation of the scheduled charging waiting time Δt in the embodiment of the present invention. start Not relevant, so it is not a necessary step.

[0089] 2. Charging with rate

[0090] In this case, the initial charging time is also calculated as t3-Δt; then according to the initial charging time t3-Δt and the interval [t f1 , t f2 ] and the relationship between the charging gun connection time t and the interval [t3-Δt, t3], determine the scheduled charging waiting time Δt start .

[0091] 1) FIG. 5(a) and FIG. 5(b) are examples of an embodiment of the present invention in which the initial charging time is less than the rate charging start time t f1 5(a) also shows the time relationship when the charging gun connection time is less than the initial charging time, and FIG. 5(b) also shows the time relationship when the charging gun connection time is greater than or equal to the initial charging time and less than the vehicle use time.

[0092] 11) As shown in Figure 5(a), that is, t3-Δt <t f1 And t<t3-Δt, at this time, the charging gun has been connected before the initial charging time, and the preferential rate charging start time is after the initial charging time, so as long as charging is carried out before the initial charging time t3-Δt, the requirements of vehicle use time t3 and rate charging can be met at the same time, so that scheduled charging can be performed and Δt can be determined. start =t3-Δt-t.

[0093] For example, t is 13:00, t3 - Δt is 14:00, and t f1 is 15:00, t3 is 16:00, then Δt start is 1h, so it can be reserved to charge within 1 hour after 13:00, which can meet the requirements of the rate charging start time t f1 and the vehicle usage time t3.

[0094] 12) As shown in Figure 5(b), that is, t3 - Δt < t f1 and t3 - Δt ≤ t < t3. At this time, the charging gun is not connected before the initial charging start time and the rate charging start time, and it is difficult to meet the requirement of the vehicle usage time t3. Therefore, immediate charging needs to be performed to determine Δt start = 0.

[0095] For example, t3 - Δt is 14:00, t3 is 16:00, t f1 is 15:00, t is 15:15, t f2 is 15:30, so Δt start is 0, and immediate charging is performed to try to enjoy the charging discount and increase the battery power before the rate charging end time 15:30 and the vehicle usage time 16:00 arrive, so as to ensure the normal operation of the vehicle.

[0096] 13) The situation in Figure 4(c) can be referred to correspondingly. When t ≥ t3, the vehicle usage time t3 has arrived but the charging gun has not been connected yet. Therefore, for this vehicle usage, the matter of reserved vehicle usage does not need to be considered anymore, and the next vehicle usage time should be considered to determine the reserved charging waiting duration Δt start .

[0097] 14) The situation in Figure 4(d) can be referred to correspondingly, that is, t3 ≥ t3 - Δt is obviously unconventional and belongs to an invalid value. Therefore, the calculation of the reserved charging waiting duration Δt start is not required.

[0098] 2) Figure 5(c)-Figure 5(d) is a schematic diagram of the time relationship in Example 1 of the present invention where the initial charging start time is greater than or equal to the rate charging start time and less than the rate charging end time. Figure 5(c) also shows the time relationship where the charging gun connection time is less than the rate charging start time, and Figure 5(d) also shows the time relationship where the charging gun connection time is greater than or equal to the rate charging start time and less than the vehicle usage time.

[0099] 21) As shown in Figure 5(c), that is, t f1 ≤ t3 - Δt < t f2 and t < t f1, at this time, the charging gun has been connected before the initial charging start time, and the preferential rate charging start time is before the initial charging start time. Therefore, in order to enjoy the charging discount, charging should be carried out immediately when the rate charging start time arrives. At this time, charging can meet the requirements of the vehicle usage time t3 and the rate charging at the same time. Therefore, reservation charging can be executed to determine Δt start = t f1 - t.

[0100] For example, t is 13:00, t3 - Δt is 14:00, and t f1 is 13:30, t3 is 16:00, then Δt start is 30 min. Therefore, it can be reserved to charge within half an hour after 13:00 to enjoy the rate charging period.

[0101] 22) As shown in Fig. 5(d), that is, t f1 ≤ t3 - Δt < t f2 and t f1 ≤ t < t3. At this time, the charging gun has not been connected before the initial charging start time and the rate charging start time, and it is difficult to meet the requirements of the vehicle usage time. Therefore, immediate charging needs to be executed to determine Δt start = 0.

[0102] For example, t3 - Δt is 14:00, t3 is 16:00, t f1 is 13:00, t is 14:30, t f2 is 15:00, so Δt start is 0. Charge immediately to try to enjoy the charging discount and increase the battery power before the rate charging end time of 15:00 and the vehicle usage time of 16:00 arrive to ensure the normal operation of the vehicle.

[0103] 23) It is the same as the situation shown in 13) above, so it will not be elaborated here.

[0104] 24) It is the same as the situation shown in 14) above, so it will not be elaborated here.

[0105] 3) Figure 5(e)-Figure 5(h) is the time relationship diagram in Example 1 of the embodiment of the present invention where the initial charging start time is greater than or equal to the rate charging end time and less than the vehicle usage time. Fig. 5(e) also shows the time relationship where the charging gun connection time is less than the rate charging start time, Fig. 5(f) also shows the time relationship where the charging gun connection time is greater than or equal to the rate charging start time and less than the rate charging end time, Fig. 5(g) also shows the time relationship where the charging gun connection time is greater than or equal to the rate charging end time and less than the initial charging start time, and Fig. 5(h) also shows the time relationship when the charging gun connection time is greater than or equal to the initial charging start time and less than the vehicle usage time.

[0106] 31) As shown in Fig. 5(e), i.e., when t f2 ≤ t3 - Δt < t3 and t < t f1 , at this time, the charging gun has been connected before the entire rate charging period, while the initial charging start time is after the entire rate charging period. Therefore, in order to enjoy the charging discount, charging should be carried out immediately when the rate charging start time arrives. At this time, charging can meet the vehicle usage time t3 and fully enjoy the rate charging discount, so scheduled charging can be executed to determine Δt start = t f1 - t.

[0107] For example, t is 13:00, t f1 is 13:30, t f2 is 14:30, t3 - Δt is 15:00, t3 is 16:00, then Δt start is 30 min. Thus, charging can be scheduled to be carried out within half an hour after 13:00 to enjoy the rate charging period.

[0108] 32) As shown in Fig. 5(f), i.e., when t f2 ≤ t3 - Δt < t3 and t f1 ≤ t < t3, at this time, the charging gun has not been connected before the initial charging start time and the rate charging start time, and it is difficult to meet the vehicle usage time requirement. Therefore, immediate charging needs to be executed to determine Δt start = 0.

[0109] For example, t is 14:00, t f1 is 13:30, t f2 is 14:30, t3 - Δt is 15:00, t3 is 16:00, so Δt start is 0, and immediate charging is carried out to try to enjoy the charging discount and increase the battery power before the rate charging end time 14:30 and the vehicle usage time 16:00 arrive, so as to ensure the normal operation of the vehicle.

[0110] 33) As shown in Fig. 5(g), i.e., when t f2 ≤ t3 - Δt < t3 and t f2 ≤ t < t3 - Δt, at this time, the charging gun is connected after the rate charging ends. Therefore, the rate charging discount cannot be enjoyed anymore, but the initial charging start time has not arrived yet, and the vehicle usage time requirement can be met. Thus, scheduled charging can be executed to determine

[0111] Δt start = t3 - Δt - t.

[0112] For example, t is 14:45, t f1 is 13:30, tf2 is 14:30, t3 - Δt is 15:00, t3 is 16:00, then Δt start is 15 min, so it can be reserved to charge within 15 min after 14:45 to ensure that the battery charging is completed before the vehicle usage time arrives.

[0113] 34) As shown in Fig. 5(h), that is, t f2 ≤t3 - Δt < t3 and t3 - Δt ≤ t < t3. At this time, the charging gun has not been connected and completed before the initial charging start time and the rate charging period, and it is difficult to meet the requirements of the vehicle usage time. Therefore, immediate charging needs to be executed to determine Δt start = 0.

[0114] For example, t is 15:30, t f1 is 13:30, t f2 is 14:30, t3 - Δt is 15:00, t3 is 16:00, so Δt start is 0, and immediate charging is carried out to try to enjoy the charging discount and increase the battery power before the rate charging end time of 14:30 and the vehicle usage time of 16:00 arrives, so as to ensure the normal operation of the vehicle.

[0115] 35) It is the same as the situation shown in 13) above, so it will not be elaborated here.

[0116] 36) It is the same as the situation shown in 14) above, so it will not be elaborated here.

[0117] In summary, step S100 realizes the calculation of the reservation charging waiting duration in the gateway device (GW).

[0118] Furthermore, for step S200, this example 1 mainly realizes timing in the GW and sending a charging permission signal to the HCU.

[0119] For example, after the GW determines the reservation charging waiting duration Δt start it starts timing and takes the last received Δt start as the standard. When the timing reaches Δt start the whole vehicle should be woken up and a charging permission status signal should be sent to the HCU. After the HCU receives the charging permission status signal sent by the T_box, it judges whether the vehicle can be charged. If so, it charges normally; when the charging is completed, the whole vehicle executes the charging power-off process, and all electronic control units (Electronic Control Unit, ECU) go to sleep by themselves.

[0120] Furthermore, after sending a charging permission signal to the vehicle control unit of the vehicle, the vehicle scheduled charging control method further includes: in response to the charging status fed back by the vehicle control unit, feeding back a scheduled charging start signal to the vehicle's backend server. Continuing with the example, after receiving the scheduled charging start signal, the TSP can determine whether the charging gun is connected. If not, the smartphone APP is notified to prompt "scheduled charging has started, please connect the charging gun"; if connected, the APP is notified to display the charging status.

[0121] Figure 6 This is a flowchart of Example 1 for implementing scheduled charging, which takes TSP, T-box, HUT, APP, OBC, BMS, and HCU as examples. Figure 6 The process of charging reservation implemented in this example may include the following steps:

[0122] Step S601: GW obtains charging related information.

[0123] The charging-related information may be set in the APP or HUT, for example, using the method shown in FIG. 3( a ) and FIG. 3( b ).

[0124] Step S602: GW obtains the charging gun connection status and the estimated charging time.

[0125] The charging gun connection status is detected by the OBC and sent to the GW when the charging gun is connected, and the charging gun connection status includes the charging connection time.

[0126] The estimated charging time Δt is obtained by BMS analysis and sent to GW.

[0127] Step S603: GW calculates the waiting time for scheduled charging as Δt start .

[0128] Among them, the scheduled charging waiting time is Δt start For example, the respective calculations may be performed with reference to the various situations shown in FIG. 4 and FIG. 5 .

[0129] Step S604, GW starts timing

[0130] Step S605: GW timing reaches Δt start When the charging is started, a charging permission signal is sent to the HCU, and a reserved charging start signal is sent to the TSP through the T-box.

[0131] Step S606 , the HCU executes the charging power-on process and performs scheduled charging in response to the charging permission signal, and feeds back the charging status to the GW.

[0132] Step S607: GW sends the charging status and current charging gun connection status to TSP via T-box.

[0133] Among them, the charging gun connection status is still obtained by OBC detection.

[0134] In addition, TSP can respond to the scheduled charging start signal and send a prompt instruction to the APP according to the charging status and the charging gun connection status. Among them, according to different charging status and charging gun connection status, the corresponding prompt instruction content is different. For example, if the charging gun is not connected, the APP is commanded to prompt "Scheduled charging has started, please connect the charging gun". If the charging gun is connected, the APP is commanded to synchronize the animation to display the charging status. The APP can provide charging prompts, and it should be noted that, referring to Figures 3(a) and 3(b), the APP and HUT can provide relevant prompts synchronously.

[0135] Finally, the HUT executes the charging and power-off process after charging is completed, while the T-box and TSP go into sleep mode by themselves after their respective sleep conditions are met.

[0136] Based on this, in this example, GW calculates the waiting time for scheduled charging, counts the scheduled charging time, and performs timed wake-up, while T-box is only responsible for signal forwarding, HCU and OBC are responsible for information detection and storage, BMS is responsible for calculating the estimated charging time, HUT and APP are responsible for displaying the charging information settings, and each part collaborates to complete the scheduled charging and optimizes the weight of the scheduled charging function that T-box is responsible for.

[0137] Therefore, Example 1 of the embodiment of the present invention uses the in-vehicle gateway device to calculate and time the reservation time, optimizes the weight of the T-box in the charging function, and avoids the problem of frequent T-box failures caused by the excessive weight of the T-box in the charging function. In addition, the reservation charging of Example 1 does not depend on the TSP, so it can be applied to the scenario where the network condition between the T-box and the TSP is poor.

[0138] Example 2: Vehicle scheduled charging control method applied to a vehicle host.

[0139] Compared with Example 1, Example 2 adjusts the vehicle reservation charging control method implemented on the gateway device to be implemented on the vehicle host, and the implementation details are similar.

[0140] However, when the vehicle scheduled charging control method of Example 1 is implemented on a vehicle-mounted host (such as HUT), that is, when the in-vehicle computing unit is HUT, corresponding to Figures 3(a) and 3(b), the signals GW_Week_Hour_Min, GW_Rate_Star_Hour_Min, and GW_Rate_End_Hour_Min should be replaced by HUT_Week_Hour_Min, HUT_Rate_Star_Hour_Min, and HUT_Rate_End_Hour_Min. In addition, it is easy to know that because HUT has the basic functions of information display and information setting, when the in-vehicle computing unit is HUT, it is equivalent to the in-vehicle computing unit directly completing the scheduled charging setting or display involved in Figures 3(a) and 3(b).

[0141] For other implementation details and effects of Example 2, please refer to Example 1 and will not be described in detail here.

[0142] Example 3: Vehicle scheduled charging control method applied to battery management system.

[0143] Compared with Example 1 and Example 2, Example 3 changes the vehicle scheduled charging control method implemented on the gateway device or the vehicle host to be implemented on the battery management system, and the implementation details are similar.

[0144] However, for example, when the vehicle scheduled charging control method of Example 1 or Example 2 is implemented on a battery management system (such as BMS), that is, when the in-vehicle computing unit is a BMS, corresponding to Figure 3(a) and Figure 3(b), the signal fed back by the BMS should be replaced with BMS_Week_Hour_Min, BMS_Rate_Star_Hour_Min and BMS_Rate_End_Hour_Min.

[0145] In addition, since the BMS has the basic function of power analysis, it is equivalent to the in-vehicle computing unit directly completing the power analysis and obtaining information such as the scheduled charging time in step S100.

[0146] For other implementation details and effects of Example 3, please refer to Example 1 and will not be described in detail here.

[0147] Example 4: Vehicle reservation charging control method applied to power chassis domain controller.

[0148] Compared with Examples 1 to 3, Example 4 changes the vehicle reservation charging control method implemented on the gateway device, the vehicle host or the battery management system to be implemented on the vehicle's power chassis domain controller, and the implementation details are similar.

[0149] It should be noted that Example 4 is only applicable to vehicles with a power chassis domain controller, such as many existing unmanned vehicles. The power chassis domain controller integrates the core control of the vehicle's electric system, has rich functions, and can communicate with HCU, HUT, BMS, etc. through GW, so it can be considered to use it to implement the vehicle reservation charging control method of the embodiment of the present invention.

[0150] However, for example, when the vehicle reservation charging control method of Example 1 or Example 2 is implemented on the power chassis domain controller, that is, when the in-vehicle computing unit is the power chassis domain controller, corresponding to Figure 3(a) and Figure 3(b), the signal fed back by the power chassis domain controller should be replaced with power chassis domain controller_Week_Hour_Min, power chassis domain controller_Rate_Star_Hour_Min and power chassis domain controller_Rate_End_Hour_Min.

[0151] For other implementation details and effects of Example 4, please refer to Example 1 and will not be described in detail here.
