[0035] Here, the technical solutions in the embodiments (or "implementations") of the present application will be described clearly and completely in conjunction with the accompanying drawings. When the following description refers to the drawings, unless otherwise indicated, the same numbers in different drawings represent the same or similar elements.

In addition, the terms "first", "second", etc. involved in the embodiments of the present application are only used for the purpose of convenience of description and cannot be understood as indicating or implying relative importance.

[0037] The present application provides a vehicle scheduled charging method and system. The present application is described in detail below in conjunction with the accompanying drawings. The features of the following embodiments and implementations can be combined with each other if there is no conflict.

[0038] At present, the implementation mode of DC charging pile reservation (timing) charging mainly relies on mobile phone APP to remotely operate the DC charging pile. The car owner sets the charging start time of the charging pile through the mobile phone APP to achieve this. However, this mode has certain disadvantages. If the signal is poor, the DC charging pile is very likely to be unable to smoothly receive and execute the reservation (timing) charging instructions issued by the mobile phone APP, which will lead to the obstruction of the charging plan and the inability to achieve the expected energy replenishment effect. At the same time, when the car owner sets the charging start time of the charging pile through the mobile phone APP to realize the reservation charging, the vehicle cannot know the reservation. If there is a communication failure or the charging pile itself has problems and cannot be charged, the vehicle itself is unprepared and the user may find it difficult to discover in time.

[0039] In order to solve the above technical problems, this specification provides a vehicle scheduled charging method.

[0040] The purpose is to establish a communication connection and information exchange between the vehicle and the charging pile through a newly added interactive protocol when the vehicle and the charging pile are connected. This can not only solve the existing problem of being unable to make charging appointments due to factors such as weak signals, but also realize active control of vehicle-side appointments and improve charging efficiency.

[0041] It should be noted that the vehicle reservation charging method described in this article is applied to the vehicle charging controller on the vehicle side, the controller of the vehicle battery management system, as well as any device or system in an independent server, cloud, Internet of Vehicles platform, Internet of Things platform, other smart terminals, etc.

[0042] In some embodiments, reference Figure 1 , Figure 1 It is a schematic diagram of a vehicle scheduled charging system provided in an embodiment of this specification.

[0043] The vehicle reservation charging system includes a reservation time setting unit, a timer, a vehicle charging controller, a charging pile (including a DC charging pile and an AC charging pile, and the DC charging pile is used as an example below), and also includes a plug for the charging pile.

[0044] The reservation time setting unit includes any one of the central control screen of the vehicle, the smart terminal connected to the vehicle, the cloud, and the application, and the reservation (timing) charging time information is set through the reservation setting unit. As an example, the reservation (timing) charging time information is set through the main control screen (DHU) or the mobile phone APP.

[0045] The timer is turned on, and when the system time on the vehicle side reaches the scheduled charging time, the vehicle charging controller is informed whether the current state is in a state where charging is allowed. The notification method includes but is not limited to notifying the vehicle charging controller in the form of an instruction on whether charging is allowed.

[0046] The vehicle charging controller is used to establish a communication connection between the vehicle end and the charging pile when the plug of the charging pile is connected to the charging interface of the vehicle end, so that the charging pile can send information whether it has the function of responding to the scheduled charging; when affirmative information is received, a charging instruction is sent to the charging pile according to the scheduled charging time set by the vehicle end, so as to execute the process of charging the vehicle end through the plug.

[0047] It can be understood that in addition to the lines for transmitting electrical energy, the charging gun and the charging interface on the vehicle side also have lines specifically used for communication to establish a connection between the vehicle and the charging pile. When the charging gun is inserted into the vehicle, the physical connection is completed. Based on this connection, information is transmitted through a specific communication protocol. This protocol specifies the format of information, the transmission rate, the encoding method of data, and other contents. For example, 00 in the message represents immediate charging, 01 represents scheduled charging, and 02 represents stop charging.

[0048] The interaction protocol between the vehicle and the charging pile also specifies how to request and respond to information. As an example, the vehicle sends an information request to the charging pile to ask whether the charging pile supports the scheduled charging function. The charging pile replies through the communication line according to its actual situation (if it supports, it returns a positive response code, and if it does not support, it returns a negative response code). These protocols ensure that the vehicle and the charging pile can communicate accurately and orderly, and realize the vehicle's control over the start and stop of the charging pile.

[0049] like Figure 2 and Figure 3 As shown, Figure 2 This is a flow chart of a vehicle charging reservation method provided by an embodiment of this specification. The specific implementation steps of this embodiment may include:

[0050] Step S100, when the plug of the charging pile is connected to the charging interface of the vehicle end, a communication connection is established between the vehicle end and the charging pile, so that the charging pile can send information on whether it has the function of responding to the scheduled charging.

[0051] The input quantities required by the vehicle charging controller to control the scheduled (timing) charging of the DC pile are as follows:

[0052] 1) The set scheduled (scheduled) charging time information;

[0053] 2) Whether charging is allowed or not, issued by the timer;

[0054] 3) The DC charging pile informs through interactive information that it has the ability to respond to scheduled (timed) charging.

[0055] The charging pile energy replenishment solution of the vehicle charging controller is introduced as follows:

[0056] The first step is to set a scheduled (scheduled) charging time on the vehicle side when there is a need for charging.

[0057] In some embodiments, the setting method of the scheduled charging time includes any one of the central control screen of the vehicle, the smart terminal connected to the vehicle, the cloud, and the application. For example, the scheduled (timed) charging time information is set through the main control screen (DHU) or the mobile phone APP.

[0058] In other embodiments, the method further includes: determining the scheduled charging time according to the battery status and current energy consumption demand of the vehicle. It can be understood that the vehicle side is the leading active control of charging, so that the vehicle's own system can be better integrated with the scheduled charging function.

[0059] As an example, the vehicle sets the scheduled charging time based on factors such as the battery's current charge level, temperature, and health status. The vehicle has greater autonomy during the entire charging process and can better adapt to different charging pile conditions and its own charging needs.

[0060] As another example, the vehicle can more reasonably arrange charging parameters such as power and duration based on factors such as the battery's current charge level, temperature, and health status, combined with the scheduled charging time, to improve the vehicle's energy economy and selectivity.

[0061] As another example, the method further includes: determining the scheduled charging time according to a time period of valley electricity prices to reduce electricity costs.

[0062] The second step is to establish a communication connection between the vehicle and the charging pile through the plug when the charging gun of the charging pile is connected to the charging interface of the vehicle. The DC charging pile informs the vehicle charging controller through the communication protocol whether it has the function of responding to the scheduled (timed) charging.

[0063] As an example, when the vehicle establishes a communication connection with the charging pile, the vehicle will first actively interact with the charging pile to confirm whether it can support the scheduled charging function. Adjust the charging strategy according to the status of the charging pile. For example, the vehicle sends an inquiry command to the charging pile to ask whether the charging pile has the function of responding to the scheduled charging function. The charging pile responds to the inquiry command and informs the vehicle charging controller whether it has the function of responding to the scheduled charging function.

[0064] As another example, when a communication connection is established between the vehicle and the charging pile, the charging pile actively informs the vehicle charging controller of whether it has the scheduled charging function based on the set communication protocol. The vehicle charging controller receives this information and adjusts the charging strategy according to the status of the charging pile.

[0065] In this embodiment, the control logic is dominated by the vehicle side, which can flexibly adjust the charging strategy according to the actual situation of the charging pile. Even if there is a problem with the external communication environment (as long as the interaction protocol between the vehicle and the charging pile can communicate normally), the vehicle can still decide whether and how to charge based on its own judgment.

[0066] Step S200, when positive information is received, a charging instruction is sent to the charging pile according to the scheduled charging time set by the vehicle end, so as to execute the process of charging the vehicle end through the plug.

[0067] Continuing with the third step of the above charging pile replenishment plan, there are two situations. One situation is that a positive message is received indicating that the charging pile has the function of responding to scheduled charging. The vehicle side will enter autonomous timing until the start time of the scheduled charging is triggered. The vehicle will actively wake up the charging pile through the interactive protocol for charging.

[0068] As an example, when receiving the affirmative information, sending a charging instruction to the charging pile according to the scheduled charging time set by the vehicle end includes:

[0069] When positive information is received, if an instruction to allow charging is obtained from the vehicle timer based on the scheduled charging time, a charging instruction is sent to the charging pile.

[0070] Among them, the system time t1 of the vehicle end and the set scheduled charging time t2 are compared through the vehicle timer; when the vehicle timer determines that the system time t1 ≥ the scheduled charging time t2, a charging permission instruction is issued; when the vehicle timer determines that the system time t1 < the scheduled charging time t2, a charging disallowance instruction is issued.

[0071] According to the instruction to allow charging issued by the vehicle timer, the vehicle charging controller sends a charging instruction to the charging pile through the communication protocol, that is, instructs the charging pile to start charging.

[0072] In this embodiment, according to the charging permission instruction sent by the vehicle timer, the vehicle controller is controlled to inform the DC charging pile to start charging through the communication protocol.

[0073] As another example, when receiving the affirmative information, sending a charging instruction to the charging pile according to the scheduled charging time set by the vehicle end includes:

[0074] In case of receiving affirmative information, obtaining a charging mode of the vehicle end, wherein the charging mode includes an instant charging mode and a scheduled charging mode;

[0075] When the vehicle end is in the instant charging mode, a charging instruction is sent to the charging pile.

[0076] Among them, the vehicle timer compares the system time t1 of the vehicle end with the set scheduled charging time t2. When the system time t1 is greater than or equal to the scheduled charging time t2, the vehicle charging controller is informed that it is currently in the charging mode, that is, it is determined that the vehicle end is in the immediate charging mode. When the system time t1 is less than the scheduled charging time t2, the vehicle charging controller is informed that it is currently in the scheduled (timing) charging mode, that is, the vehicle end is in the scheduled charging mode.

[0077] The vehicle charging controller is in reservation mode and does not allow charging temporarily until the vehicle timer waits for time t1=t2, and then the vehicle controller sends a charging instruction (such as charging immediately) through the communication protocol to wake up the charging pile for charging.

[0078] In this embodiment, according to the charging mode of the vehicle, the vehicle controller is controlled to inform the DC charging pile to start charging through the communication protocol. The judgment of the vehicle charging mode can be implemented in the vehicle timer or in the vehicle charging controller, which greatly improves the flexibility and reliability of the charging strategy.

[0079] Continuing with the third step of the above charging pile energy replenishment plan, another situation is that receiving a negative message indicates that the charging pile does not have the function of responding to the scheduled charging, then the vehicle will actively wake up the charging pile through the interactive protocol for charging and enter the normal national standard charging interactive process.

[0080] As an example, the method further includes: in the case of receiving negative information, sending a charging instruction to the charging pile to execute the process of charging the vehicle end through the plug.

[0081] In this embodiment, the vehicle can adjust the charging strategy in real time according to the actual situation of the charging pile. When it is found that the charging pile does not support scheduled charging, the vehicle can quickly switch to the normal charging process without wasting time waiting for the appointment, thereby improving the charging efficiency.

[0082] The fourth step is that when the charging end conditions are met, the whole vehicle controls the charging pile to replenish energy.

[0083] As an example, the charging end conditions include but are not limited to the charging time reaching the charging end time set when the charging is scheduled on the vehicle side, the power of the vehicle side battery reaches the threshold corresponding to the full state, etc.

[0084] When the charging end conditions are met, the vehicle controller sends a charging instruction (such as message 02 or stop charging, etc.) through the communication protocol to control the charging pile to stop charging and end the energy replenishment action.

[0085] The present application provides a vehicle scheduled charging method and system. Compared with the current charging control of the charging pile by a mobile phone application, which is affected by the signal and causes charging to be blocked, a wired communication connection is established between the vehicle end and the charging pile when the plug of the charging pile is connected to the charging interface of the vehicle end. It does not rely on network signals, effectively guarantees stable communication between the vehicle end and the charging pile, receives information sent by the charging pile on whether it has the function of responding to scheduled charging, and provides a stable basis for the charging pile to execute charging instructions. When the vehicle charging controller receives positive information, it indicates that the charging pile has the function of responding to scheduled charging. Then, according to the scheduled charging time set by the vehicle end, when the system time of the vehicle end reaches the scheduled charging time, a charging instruction is sent to the charging pile to wake up the charging pile, and the process of charging the vehicle end through the plug is executed to realize the scheduled charging of the vehicle.

[0086] Based on the same application concept as the above method, an embodiment of the present application also proposes a whole vehicle charging controller, including a memory, a processor and a vehicle reservation charging program stored in the memory and executable on the processor, and when the processor executes the vehicle reservation charging program, the steps of the vehicle reservation charging method as described above are implemented.

[0087] The implementation process of the functions and effects of each module / sub-module / unit in the above-mentioned vehicle charging controller is specifically described in the implementation process of the corresponding steps in the above-mentioned method, and the same technical effect can be achieved, so it will not be repeated here.

[0088] Based on the same application concept as the above method, the embodiment of the present application also proposes a vehicle reservation charging system, including the vehicle charging controller and charging pile as described above; when the plug of the charging pile is connected to the charging interface of the vehicle end, a communication connection between the vehicle end and the charging pile is established, which is used to send a charging instruction to the charging pile through the vehicle charging controller to execute the process of charging the vehicle end through the plug.

[0089] The implementation process of the functions and effects of each module / sub-module / unit in the above system is specifically described in the implementation process of the corresponding steps in the above method, and the same technical effect can be achieved, so it will not be repeated here.
