[0002] The statements in this part only provide background art related to the present invention and do not necessarily constitute prior art.

[0003] When a new energy battery needs to be charged, generally, the user plugs in the charging gun and charges immediately. In real life, electricity prices are divided into peak electricity prices and off-peak electricity prices, resulting in a large economic difference; in addition, since some users use the vehicle regularly, such as using the vehicle during the day and not using it at night, when the user plugs in the charging gun, it is not necessarily necessary to charge immediately. Therefore, it is necessary to configure a reservation charging function for the vehicle.

[0004] The inventor found that the existing reservation charging function focuses on setting the reservation time and the charging power, and completes the charging after the charging time arrives or the charging power arrives, lacking feedback control during the charging execution process, and thus unable to effectively balance the safety and intelligence during the reservation charging process.

[0047] The present invention will be further described below in conjunction with the drawings and embodiments.

[0048] It should be noted that the following detailed descriptions are all illustrative and are intended to provide further explanations of the present invention. Unless otherwise specified, all technical and scientific terms used herein have the same meaning as commonly understood by those of ordinary skill in the technical field to which the present invention belongs.

[0049] It should be noted that the terms used herein are only for describing specific implementation manners and are not intended to limit the exemplary embodiments according to the present invention. As used herein, unless the context clearly indicates otherwise, the singular forms are also intended to include the plural forms. In addition, it should be understood that when the terms "comprising" and / or "including" are used in this specification, they indicate the presence of features, steps, operations, devices, components, and / or their combinations.

[0050] Without conflict, the embodiments in the present invention and the features in the embodiments can be combined with each other.

[0051] Embodiment 1:

[0052] Embodiment 1 of the present invention provides a system for realizing the scheduled charging function of new energy vehicles. On the car host control screen, the scheduled charging function is added; the scheduled charging function includes the scheduled start charging time, end time, or charging duration, and the scheduled charging repetition period, such as options for every day or from Monday to Sunday; at the same time, the setting of the scheduled charging power can also be added, such as the total scheduled charging power, charging target mileage, charging cut-off SOC, etc., as specifically shown in Figure 1 as shown.

[0053] In this embodiment, the charging start time can be set, for example, charging starts at 23:00; the charging period can be set with a charging time period, for example, charging from 23:00 to 7:00; the vehicle usage time can be set with the start vehicle usage time, for example, starting to use the vehicle at 8:00; the reserved charging cycle can be set to whether to set cyclically, such as every day, every Monday, the 1st of each month, etc., as Figure 2 shown.

[0054] In this embodiment, the charging power can be set, for example, the total reserved charging power is up to 15 kWh; it can be set to a charging target mileage of 300 km; it can be set to a charging cut-off SOC of 80%.

[0055] In this embodiment, when the user sets up reserved charging on the host screen and then plugs in the charging gun, the vehicle goes into normal sleep; the reserved information is synchronized by the host IHU to the TBOX.

[0056] In this embodiment, when the reserved charging time is reached, the TBOX wakes up each relevant module of the vehicle, such as the instrument, the host IHU, the gateway CGW, the hybrid control unit HCU, the charging system OBC, the battery management system BMS, etc.; each relevant module controls to start charging according to the reserved time, and displays charging-related information on the instrument ICM or the host IHU.

[0057] More specifically, it includes:

[0058] (1) Necessary conditions

[0059] A) The vehicle has a vehicle networking function such as TBOX. At this time, the main function of the TBOX is to still maintain the time calibration and network management signal transmission function when the vehicle is in sleep;

[0060] The time calibration is mainly divided into three modes: the first is RTC calibration, which uses the high-precision crystal oscillator and peripheral circuits inside the TBOX hardware to keep synchronized with the initial time; the second is GPS calibration, which performs time synchronization with the external GPS signal in real time or at intervals through networking with the external GPS signal to achieve time calibration; the third is network calibration, which connects to the external communication network through the network communication module of the TBOX to obtain the network time for time calibration, and generally selects a combination verification of the two methods;

[0061] B) The vehicle needs to have a reserved charging function; this reservation function means that the vehicle IHU or instrument or hard switch supports the setting of the reserved charging time and cycle;

[0062] C) The BMS system supports the opening and closing of the charging system through network application messages; because the reserved charging function is realized by the TBOX waking up relevant function modules through network signals, the BMS system needs to support the network signal wake-up function.

[0063] (2) Implementation method

[0064] When the vehicle is in sleep mode, the TBOX is not fully asleep. While maintaining the lowest power consumption of the entire vehicle, it only maintains the basic functions of networked time update and network signal transmission.

[0065] A) Implementation of local reservation

[0066] The user sets reservation charging information through local methods such as the host IHU, instrument panel, or hard switch, sends and stores it in the TBOX, and the TBOX is responsible for timing. Before the vehicle goes to sleep, the TBOX feeds back the set information, which is then displayed by the instrument panel or IHU. After the reservation time arrives, the TBOX wakes up relevant modules such as the ICM, IHU, CDU, HCU, BMS, TSP, etc. through network management messages. After the relevant modules are awakened, the TBOX determines the connection status of the charging gun, as Figure 3 shown;

[0067] B) Implementation of remote reservation

[0068] Set various reservation parameters on the mobile APP. The TSP sends the charging mode and reservation charging plan to the TBOX according to the TSP communication protocol. The TBOX responds according to the TSP request and stores the relevant set information, and then sends it to each module for execution according to the relevant parameters. This step is the same as that of local reservation. In subsequent stages such as reservation waiting, start of reservation charging, end of reservation charging, etc., feedback is made according to the TSP protocol and is reflected on the mobile APP, as Figure 4 shown.

[0069] (3) Interaction logic of reservation charging

[0070] When the reservation charging time arrives, the TBOX wakes up the network. At the same time, it determines whether charging is possible based on the connection status signal of the charging gun. When the charging gun is connected without problems, it sends an allow-charging signal. After receiving the allow-charging signal, the BMS turns on the relevant charging hardware and starts charging. Otherwise, it sends a charging failure signal, the BMS does not perform the charging action, and this signal is fed back to the IHU or the TSP to the mobile phone side to indicate charging failure;

[0071] After starting charging, the TBOX receives the charging current signal sent by the BMS to determine the charging status. For example: determine whether the charging current is negative. If the current is negative, it feeds back that the instruction execution is successful. If the current is non-negative, then determine whether the SOC is 100%. If the SOC value is 100%, it feeds back that the execution is successful. If the SOC is not 100%, then determine the charging status. If the charging status is heating, it feeds back that the execution is successful. If it is not heating, it feeds back that the execution fails;

[0072] When it is determined that the charging execution result is successful and the vehicle is charging, continuously monitor the charging current and the change in the charging gun connection status: If the charging gun connection changes to disconnected, determine whether the SOC is 100%. If not, feedback that the charging fails, and the reason for the failure is that the charging gun is not connected; if the SOC is 100%, there is no need to feedback the result, and this process ends; if the charging current jumps to a non - negative value, determine the SOC value. If the SOC is 100%, this process ends; if the SOC is not 100%, feedback the charging failure and the reason for the failure.

[0073] When it is determined that the charging execution result is successful and the charging status is heating, continuously detect the charging status. If the charging status jumps to charging, continue to monitor; if the charging status jumps to other status, report a charging failure.

[0074] In this embodiment, there is no priority between the scheduled charging settings of the IHU and those on the mobile APP. If they are set simultaneously, the TBOX makes the final setting according to the last received setting.

[0075] In this embodiment, when the vehicle is in the sleep state and a scheduled setting is made on the mobile APP side, the TBOX needs to determine whether the current time point is within the allowed charging range set. If it is within the allowed charging range, the TBOX wakes up the network, sends a charging permission signal to the HCU, and at the same time, synchronizes the relevant settings to the IHU; if it is determined that the current time is not within the allowed charging range, after the reservation is successful, the reservation information is not synchronized to the IHU temporarily (the TBOX does not wake up the CAN network), and the relevant reservation information is synchronized again when the vehicle network wakes up next time.

[0076] (4) Charging conditions:

[0077] Charging gun insertion: Before the scheduled time, the charging gun needs to be correctly inserted.

[0078] (5) Canceling the reservation before the scheduled time

[0079] A) Canceling the reservation can be switched to immediate charging;

[0080] B) Canceling the reservation can also re - enter the setting state.

[0081] (6) Charging end

[0082] After reaching the scheduled time to start charging and fully charging for the scheduled time or amount of electricity, each module should stop charging, and at the same time, the TBOX should start the next round of timing.

[0083] (7) Instrument display

[0084] A) When the scheduled charging time has not been reached, the instrument displays the remaining time until the scheduled charging start time, and at the same time displays the reserved items such as the scheduled time, cycle, amount of electricity, etc.Figure 5 as shown

[0085] B) After starting charging when the reserved charging time is reached, the instrument displays the remaining time until full charge or the target power, etc., and at the same time displays the charging effect, so that the user can intuitively feel the current charging status, such as Figure 6 as shown

[0086] (8) All instrument displays need to have a certain display time, such as 30 seconds before going to sleep, to prevent the entire vehicle from being unable to go to sleep due to instrument display, unless a strategy of not putting the entire vehicle to sleep after using the reservation setting is adopted.

[0087] Embodiment 2:

[0088] Embodiment 2 of the present invention provides a method for implementing the reserved charging function of a new energy vehicle, including the following processes:

[0089] Obtain the reserved charging time or the reserved charging power;

[0090] According to the obtained reserved charging time or the reserved charging power, perform charging control on the new energy vehicle. After starting charging, judge the charging status according to the charging current signal, including:

[0091] Judge whether the charging current is negative. If the charging current is negative, feedback that the charging execution is successful; if the current is non - negative, judge whether the SOC is 100%. If the SOC value is 100%, feedback that the charging execution is successful. If the SOC is not 100%, judge the charging status. If the charging status is heating, feedback that the charging execution is successful. If it is not heating, feedback that the charging execution fails.

[0092] Specifically, when it is judged that the charging execution is successful and charging is in progress, continuously monitor the jump of the charging current and the charging gun connection status:

[0093] If the charging gun connection becomes disconnected, judge whether the SOC is 100%. If not, feedback that the charging fails, and the reason for failure is that the charging gun is not connected;

[0097] If the charging status jumps to charging, continuously monitor; if the charging status jumps to other states, report that the charging fails;

[0098] The detailed charging process is the same as that in Embodiment 1. Here, a vehicle-mounted controller can be used to implement the control of scheduled charging, which will not be elaborated here.

If the charging state is heating, feedback that the charging execution is successful. If it is not heating, feedback that the charging execution fails.

[0104] More specifically, when it is judged that the charging execution is successful and charging is in progress, continuously monitor the jump of the charging current and the charging gun connection state:

[0105] If the charging gun connection becomes disconnected, judge whether the SOC is 100%. If not, feedback that the charging fails, and the reason for the failure is that the charging gun is not connected;

[0106] If the SOC is 100%, there is no need to feedback the result, and the current charging process ends;

[0107] If the charging current jumps to non-negative, judge the SOC value. If the SOC is 100%, the current charging process ends. If the SOC is not 100%, feedback the charging failure and the reason for the failure.

The charging control includes: After starting charging, judge the charging status according to the charging current signal; judge whether the charging current is negative. If the charging current is negative, feedback that the charging is executed successfully; if the current is non - negative, judge whether the SOC is 100%. If the SOC value is 100%, feedback that the charging is executed successfully. If the SOC is not 100%, judge the charging status. If the charging status is heating, feedback that the charging is executed successfully. If it is not heating, feedback that the charging fails; When it is judged that the charging is executed successfully and charging is in progress, continuously monitor the jump of the charging current and the charging gun connection status: If the charging gun connection becomes disconnected, judge whether the SOC is 100%. If not, feedback that the charging fails, and the reason for failure is that the charging gun is not connected; If the SOC is 100%, there is no need to feedback the result, and this charging process ends; If the charging current jumps to non - negative, judge the SOC value. If the SOC is 100%, this charging process ends. If the SOC is not 100%, feedback the charging failure and the reason for failure; When it is determined that the charging is successfully executed and heating is in progress, continuously detect the charging status: If the charging status changes to charging, continuously monitor it; if the charging status changes to other statuses, report charging failure.
