Finally, the charging time of the target vehicle is determined based on the front-end charging time and the plateau charging time. In this way, the charging time of the target vehicle in each charging stage can be accurately calculated, thereby obtaining a highly accurate charging time. Attached Figure Description

[0044] Figure 3 This is a schematic diagram of an electronic device according to an embodiment of this application. Detailed Implementation

[0045] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with specific embodiments and the accompanying drawings.

[0046] It should be noted that, unless otherwise defined, the technical or scientific terms used in the embodiments of this application should have the ordinary meaning understood by one of ordinary skill in the art to which this application pertains. The terms "first," "second," and similar terms used in the embodiments of this application do not indicate any order, quantity, or importance, but are merely used to distinguish different components. Terms such as "comprising" or "including" mean that the element or object preceding the word encompasses the elements or objects listed after the word and their equivalents, without excluding other elements or objects. Terms such as "connected" or "linked" are not limited to physical or mechanical connections, but can include electrical connections, whether direct or indirect. Terms such as "upper," "lower," "left," and "right" are only used to indicate relative positional relationships; when the absolute position of the described object changes, the relative positional relationship may also change accordingly.

[0047] The battery charging process includes an initial charging phase and a plateau charging phase. The initial charging phase is the first stage of charging when the vehicle begins charging. During this phase, the battery temperature gradually increases, and the current gradually increases. After the initial charging phase is completed, the battery temperature remains relatively stable, and the battery charging enters a more stable phase, the plateau charging phase. Towards the end of the plateau charging phase, when the battery is almost fully charged, the charging current decreases, and the charging speed slows down, but the battery temperature remains stable.

[0048] In related technologies, the calculation of vehicle charging time is usually based on the starting and ending state of charge (SOC) of the vehicle battery. For example, if the initial remaining battery charge is 10% and the expected ending remaining charge is 100%, then the charging time from the starting remaining charge to the ending remaining charge is determined based on the vehicle's historical charging records.

[0049] For vehicles, the battery temperature and charging current are stable during the plateau charging phase, so the duration of this phase is relatively fixed, with little difference between vehicles of the same model. However, due to factors such as significant differences in battery temperature and unstable current at the beginning of charging, the charging time in the initial phase is unstable, leading to inaccurate calculations of the total charging time.

[0050] To address the above issues, this application provides a method, apparatus, and vehicle for determining charging time, which can accurately calculate the charging time of the target vehicle at each charging stage, thereby obtaining a highly accurate charging time.

[0051] refer to Figure 1The first aspect of this application provides a method for determining charging time, executed by the vehicle's battery management system or the vehicle's main controller, specifically including:

[0052] Step S100: Obtain the current information of the target vehicle, including vehicle model information, current battery temperature and target remaining power.

[0053] Specifically, after the vehicle's power battery establishes a charging connection with the charging pile, the vehicle's battery management system obtains the current information of the target vehicle, and the obtained current information is used for subsequent purposes.

[0054] Step S200: Based on the vehicle model information, the current battery temperature, and the preset stable battery temperature, determine the front-end charging time of the target vehicle, wherein the preset stable battery temperature is greater than the current battery temperature.

[0055] Specifically, based on the vehicle model information, multiple charging mapping tables corresponding to the vehicle model information are determined in a preset historical charging mapping library. The preset historical charging mapping library is used to record the charging mapping relationship of the target vehicle's charging time, remaining battery power, and battery temperature.

[0056] The preset historical charging mapping library corresponds to a charging pile, meaning each charging pile has its own preset historical charging mapping library. The preset historical charging mapping library records the historical charging records of the corresponding charging pile, including the charging duration of the target vehicle, the remaining battery power of the target vehicle, and the charging mapping relationship of the target vehicle's battery temperature.

[0057] The preset historical charging mapping library includes multiple charging mapping tables, and at least one of the following in the multiple charging mapping tables is different: battery temperature, remaining power, vehicle model information, and charging time.

[0058] It should be noted that the representation of the preset historical charging mapping library is not limited in this embodiment. For example, the preset historical charging mapping library can be represented by a table. The storage location of the preset historical charging mapping library is not limited in this embodiment. For example, the preset historical charging mapping library can be stored in the storage space of the execution device executing the method for determining charging duration, or it can be stored in the storage space of another device independent of the execution device executing the method for determining charging duration.

[0059] Since the batteries of vehicles of the same model have very little difference, during charging, multiple charging mapping tables corresponding to the vehicle model information can be determined from the preset historical charging mapping database. These multiple charging mapping tables serve as the basis for subsequently determining the charging time. Determining multiple corresponding charging mapping tables based on the vehicle model information ensures that all charging mapping tables are identical to the target vehicle model, thus improving the accuracy of subsequent charging time determination.

[0060] After determining multiple charging mapping tables based on the vehicle model information, the front-end charging time of the target vehicle is determined using the multiple charging mapping tables based on the current battery temperature and the preset stable battery temperature.

[0061] The battery charging process includes an initial charging phase and a plateau charging phase. The initial charging phase refers to the moment when the battery just starts charging. When a vehicle begins charging, it first enters this initial charging phase. During this phase, the battery temperature is unstable, and as the charging time increases, the battery temperature gradually rises, and the current gradually increases.

[0062] The initial charging time refers to the charging time required by the target vehicle during the initial charging phase. Since the vehicle enters the initial charging phase immediately after charging begins, the battery temperature varies significantly during this phase. Research shows that the impact of battery temperature variation on charging time during the initial charging phase is far greater than the impact of remaining battery charge. Therefore, in this application, the initial charging time is determined based on the factor with the greatest impact on charging time during the initial charging phase (i.e., battery temperature), which makes the determination of the initial charging time more accurate. Specifically, the initial charging time of the target vehicle is determined based on the current battery temperature and a preset stable battery temperature, where the preset stable battery temperature is greater than the current battery temperature.

[0063] The preset stable temperature is the temperature of the battery under stable charging state preset based on test data and practical experience. When the battery temperature reaches the preset stable temperature, it means that the battery has entered a stable charging state. Continuing to charge will not have a significant impact on the battery temperature, and the battery temperature will not change significantly. At this time, the vehicle enters the plateau charging stage from the initial charging stage.

[0064] Step S300: Based on the stable remaining power and the target remaining power, determine the plateau period charging time of the target vehicle, wherein the stable remaining power corresponds to the preset stable battery temperature;

[0065] Specifically, when the battery temperature reaches the preset stable temperature, the front-end charging phase is complete, and the vehicle enters the plateau charging phase. The plateau phase is a period where the battery temperature is relatively stable. During the plateau charging phase, both the battery temperature and the charging current are stable. Therefore, the factor that has the greatest impact on the charging time during the plateau charging phase is the remaining battery capacity. Thus, in this application, during the plateau charging phase, the plateau charging time of the target vehicle is determined based on the stable remaining capacity and the target remaining capacity. The stable remaining capacity corresponds to the preset stable battery temperature; the stable remaining capacity is the remaining battery capacity when the target vehicle's battery temperature reaches the preset stable battery temperature.

[0066] Step S400: Determine the charging time of the target vehicle based on the front-end charging time and the plateau period charging time.

[0067] Specifically, based on the initial charging time and the plateau charging time, the charging time of the target vehicle is determined. This can be achieved by summing the initial charging time and the plateau charging time. Alternatively, based on testing experience, a front-end correction coefficient and a plateau correction coefficient can be set for the initial charging time and / or the plateau charging time, respectively. Then, the initial charging time is multiplied by the front-end correction coefficient to obtain a first time, and the plateau charging time is multiplied by the plateau correction coefficient to obtain a second time. The sum of the first and second times is then determined as the charging time of the target vehicle. The specific method for determining the charging time is set according to actual needs. In this embodiment, the sum of the initial charging time and the plateau charging time is used to determine the charging time of the target vehicle.

[0068] The method for determining charging time provided in this application divides the charging stage of the target vehicle into a front-end charging stage and a plateau charging stage. The front-end charging time and the plateau charging time of the target vehicle are determined based on different influencing factors. First, the front-end charging time is determined based on the factor that has the greatest impact on the charging time in the front-end charging stage (i.e., battery temperature). Then, the plateau charging time is determined based on the factor that has the greatest impact on the charging time in the plateau charging stage (i.e., remaining battery capacity). Finally, the charging time of the target vehicle is determined based on the front-end charging time and the plateau charging time. In this way, the charging time of the target vehicle in each charging stage can be accurately calculated, thus obtaining a highly accurate charging time.

[0069] In some embodiments, step S200, based on the vehicle model information, current battery temperature, and preset stable battery temperature, determines the front-end charging time of the target vehicle, and further includes:

[0070] Step S220: Based on the current battery temperature and the preset stable battery temperature, determine a first target charging mapping table corresponding to the current battery temperature and the preset stable battery temperature from the plurality of charging mapping tables;

[0071] Step S230: From the first target charging mapping table, find the first charging time corresponding to the current battery temperature and the second charging time corresponding to the preset stable battery temperature;

[0072] Step S240: Determine the front-end charging duration based on the first charging duration and the second charging duration.

[0073] Specifically, in step S220, based on the current battery temperature and the preset stable battery temperature, a first target charging map table corresponding to the current battery temperature is determined from the plurality of charging map tables. This specifically includes determining at least one first target charging map table from the plurality of charging map tables whose battery temperature simultaneously includes both the current battery temperature and the preset stable battery temperature. For example, the plurality of charging map tables are charging map table A, charging map table B, charging map table C, and charging map table D. The battery temperatures corresponding to charging map tables A, B, C, and D are respectively 15℃~30℃, 18℃~30℃, 20℃~30℃, and 25℃~35℃, etc. The current battery temperature is 20℃, and the preset stable battery temperature is 30℃. Therefore, the first target charging map tables determined from the plurality of charging map tables whose battery temperature simultaneously includes both the current battery temperature of 20℃ and the preset stable battery temperature of 30℃ are charging map tables A, B, and C. Since the battery charging differences for specific vehicle models are not significant, one of the charging mapping tables A, B, and C can be used as the first target charging mapping table.

[0074] Then, from the first target charging mapping table, the first charging time corresponding to the current battery temperature and the second charging time corresponding to the preset stable battery temperature are looked up. Finally, based on the first charging time and the second charging time, the front-end charging time is determined. Specifically, the difference between the second charging time and the first charging time is determined as the front-end charging time of the target vehicle.

[0075] For example, if the current battery temperature is 20°C and the preset stable battery temperature is 30°C, then from the first target charging mapping table, find the first charging time of 30 minutes corresponding to the current battery temperature of 20°C and the second charging time of 60 minutes corresponding to the preset stable battery temperature of 30°C. Then, determine the difference of 30 minutes between the second charging time of 60 minutes and the first charging time of 30 minutes as the front-end charging time of the target vehicle.

[0076] In this application, the front-end charging time is determined based on the battery temperature, which has the greatest impact on the charging time during the front-end charging phase, thus making the determination of the front-end charging time more accurate.

[0077] In some embodiments, step S300 determines the plateau charging duration of the target vehicle based on the stable remaining battery power and the target remaining battery power, including:

[0078] Step S310: Based on the stable remaining power and the target remaining power, determine a second target charging mapping table corresponding to the stable remaining power and the target remaining power from the plurality of charging mapping tables;

[0079] Step S320: From the second target charging mapping table, find the third charging duration corresponding to the stable remaining power and the fourth charging duration corresponding to the target remaining power;

[0080] Step S330: Determine the plateau period charging duration based on the third charging duration and the fourth charging duration.

[0081] Specifically, the stable remaining battery capacity corresponding to the preset stable battery temperature is found from the first target charging mapping table. The stable remaining battery capacity is the remaining battery capacity when the target vehicle's battery temperature reaches the preset stable battery temperature.

[0082] In step S310, based on the stable remaining power and the target remaining power, a second target charging map corresponding to the stable remaining power and the target remaining power is determined from the plurality of charging map tables. Specifically, this includes determining at least one second target charging map table from the plurality of charging map tables where the battery remaining power simultaneously includes both the stable remaining power and the target remaining power. For example, the plurality of charging map tables are charging map table E, charging map table F, charging map table G, and charging map table H. The battery remaining power SOC corresponding to charging map table E, charging map table F, charging map table G, and charging map table H are respectively 10%–90%, 20%–90%, 20%–100%, and 10%–100%, etc. The stable remaining power is 20%, and the target remaining power is 100%. Therefore, the second target charging map tables that simultaneously include the stable remaining power of 20% and the target remaining power of 100% are charging map tables G and G. Since the battery charging differences for specific vehicle models are not significant, one of the G charging map table and the H charging map table can be used as the second target charging map table.

[0083] Then, from the second target charging mapping table, the third charging duration corresponding to the stable remaining battery power and the fourth charging duration corresponding to the target remaining battery power are retrieved. Finally, based on the third and fourth charging durations, the plateau period charging duration is determined. Specifically, the difference between the fourth and third charging durations is determined as the plateau period charging duration for the target vehicle.

[0084] For example, if the stable remaining battery capacity is 20% and the target remaining battery capacity is 100%, then from the second target charging mapping table, find the third charging time of 10 minutes corresponding to the stable remaining battery capacity of 20% and the fourth charging time of 140 minutes corresponding to the target remaining battery capacity of 100%. Then, determine the difference of 130 minutes between the fourth charging time of 140 minutes and the third charging time of 10 minutes as the plateau period charging time of the target vehicle.

[0085] In this application, during the plateau charging phase, the remaining battery capacity is used as the factor that has the greatest impact on the charging time during the plateau charging phase to determine the plateau charging time, which can make the determination of the plateau charging time more accurate.

[0086] In some embodiments, the method for determining the charging duration further includes:

[0087] Step S500: Obtain the current charging location of the target vehicle and the historical charging interruption record table corresponding to the current charging location;

[0088] Step S600: Obtain the starting charging time of the target vehicle; based on the starting charging time and the historical charging interruption record table, determine the average charging interruption duration of the current charging location within a preset duration, wherein the preset duration is longer than the charging duration.

[0089] Step S700: Determine the final charging time based on the charging duration and the average charging interruption duration.

[0090] Specifically, the historical charging interruption record table is used to record data related to the charging interruption, such as the charging interruption time, charging interruption duration, and the time when charging resumes after the interruption, at the corresponding charging location (i.e., charging pile).

[0091] In step S600, the starting charging time of the target vehicle is obtained. Based on the starting charging time and the historical charging interruption record table, the average charging interruption duration of the current charging location within a preset duration is determined. The preset duration is longer than the charging duration, specifically including:

[0092] Step S610 determines the charging start time interval based on the starting charging time, wherein the charging start time interval includes multiple historical charging start times.

[0093] Step S620: Based on each of the historical charging start times, find the charging interruption duration of the current charging position within a preset duration from the historical charging interruption record table since that historical charging start time.

[0094] Step S630 determines the average charging interruption duration based on the multiple charging interruption durations.

[0095] In step S610, based on the initial charging time, a charging start time interval is determined. This charging start time interval is the time interval obtained by subtracting a preset start duration from the initial charging time. The preset start duration is preset based on testing experience and actual needs. In this embodiment, the preset start duration is 20 minutes. For example, if the initial charging time is 13:20, then the charging start time interval obtained by subtracting the preset start duration from 13:20 is 13:00 to 13:40. The charging start time interval includes multiple historical charging start times such as 13:00, 13:10, 13:20, 13:30, and 13:40.

[0096] In step S620, based on each historical charging start time, the charging interruption duration within a preset time period for the current charging position is retrieved from the historical charging interruption record table since that historical charging start time. The preset time period is slightly longer than the charging duration to improve the accuracy of the determined average charging interruption duration. The preset time period is the charging duration plus a preset value, which is set based on actual testing experience. In this application, the preset value is 10 minutes. For example, if the charging duration is 130 minutes, then the preset time period is the charging duration of 130 minutes plus the preset value of 10 minutes, i.e., the preset time period is 140 minutes.

[0097] Based on each historical charging start time, the charging interruption duration within a preset time period of the current charging position is found from the historical charging interruption record table starting from that historical charging start time, and finally multiple charging interruption durations are obtained. Based on the multiple charging interruption durations, the average charging interruption duration is obtained by summing the multiple charging interruption durations.

[0098] For example, the charging start time interval includes multiple historical charging start times of 13:00, 13:10, 13:20, 13:30, and 13:40. The preset duration is 140 minutes. Based on the historical charging start time of 13:00, the charging interruption duration within 140 minutes from 13:00 is found to be 20 minutes from the historical charging interruption record table. Accordingly, the charging interruption duration corresponding to each historical charging start time is sequentially found, and then the average of the multiple charging interruption durations is obtained to obtain the average charging interruption duration.

[0099] In step S700, the final charging time is determined based on the charging duration and the average charging interruption duration. Specifically, the final charging time can be determined as the sum of the charging duration and the average charging interruption duration. Alternatively, based on actual testing experience, an interruption correction coefficient can be set for the average charging interruption duration. The average charging interruption duration is multiplied by the interruption correction coefficient to obtain the corrected average interruption duration, and the sum of the corrected average interruption duration and the average charging interruption duration is determined as the final charging time. In specific implementations, the method for determining the final charging time is selected according to actual needs. In this embodiment, the sum of the charging duration and the average charging interruption duration is determined as the final charging time.

[0100] For charging locations (i.e., charging stations), charging may be interrupted during the charging process due to factors such as current, voltage, or other influences. In this application, the duration of charging interruptions at the current charging location is considered in the determination of the final charging time, making the determination of the final charging time more realistic and accurate.

[0101] It should be noted that the method in this embodiment can be executed by a single device, such as a computer or server. The method can also be applied in a distributed scenario, where multiple devices cooperate to complete the task. In such a distributed scenario, one of these devices may execute only one or more steps of the method in this embodiment, and the multiple devices will interact with each other to complete the method described.

[0102] It should be noted that the above description describes some embodiments of this application. Other embodiments are within the scope of the appended claims. In some cases, the actions or steps recorded in the claims can be performed in a different order than that shown in the above embodiments and still achieve the desired result. Furthermore, the processes depicted in the drawings do not necessarily require a specific or sequential order to achieve the desired result. In some embodiments, multitasking and parallel processing are also possible or may be advantageous.
