Rather, these embodiments are provided so that this invention will be thorough and complete, and will fully convey the scope of the invention to those skilled in the art.

[0044] The terms "first," "second," etc., used in the specification and claims of this invention are used to distinguish similar objects and not to describe a specific order or sequence. It should be understood that such data can be interchanged where appropriate so that embodiments of the invention can be implemented in orders other than those illustrated or described herein, and the objects distinguished by "first," "second," etc., are generally of the same class and the number of objects is not limited; for example, a first object can be one or more. Furthermore, in the specification and claims, "and / or" indicates at least one of the connected objects, and the character " / " generally indicates that the preceding and following objects are in an "or" relationship.

[0045] This invention provides a charging control method for a power battery. See also... Figure 1 , Figure 1 This is a flowchart of the charging control method provided in the embodiments of this application, such as... Figure 1 As shown, it includes the following steps:

[0046] Step 101: Determine one of the multiple charging modes as the first charging mode; wherein, among the multiple charging modes, one or more of the following are different: charging upper limit, charging power, constant temperature protection setting and battery heating setting during operation.

[0047] In this step, the vehicle system is equipped with multiple charging modes to suit different user application scenarios for the vehicle, such as long-distance travel, daily commuting, and long-term storage. These multiple charging modes are distinguished by different settings for one or more of the following: charging upper limit, charging power, constant temperature protection, and battery heating during transit. There are many methods for determining the charging mode, such as system settings or user settings. The charging power can be set in several ways, such as using the standard charging power value of the power battery or determining the charging power value based on charging rules and strategies sent by the cloud server. The charging power value determined by the charging rules and strategies is calculated by the cloud battery model based on input factors such as battery status and degradation. The charging rules and strategies sent by the cloud server also include appropriately extending the charging time; during slow charging or home fast charging, the system, based on learned user charging habits, pauses charging when the battery level reaches 90% or more of the charging upper limit and resumes charging earlier based on the user's usage time habits until the battery level reaches the set charging upper limit. The constant temperature protection function comprehensively analyzes the battery status and user habits to dynamically control the battery temperature within a suitable range, preventing the vehicle from malfunctioning due to prolonged exposure to unfavorable temperature conditions. The battery in-flight heating function has multiple settings, such as selection by the vehicle system or user-defined activation. When activated, the vehicle system uses navigation, vehicle status, and learned user driving habits to plan the pre-charging preheating of the battery.

[0048] Step 102: Charge the power battery according to the first charging mode.

[0049] In this embodiment of the invention, by using multiple charging modes and different charging modes in different travel scenarios, the battery is kept in a healthier state of use, thereby slowing down battery degradation, increasing service life, meeting different travel needs of users, increasing driving range, and bringing users a good overall vehicle experience.

[0050] Optionally, one of the multiple charging modes is designated as the first charging mode, including:

[0051] Get the mode selection command sent by the user;

[0052] The charging mode selected by the mode selection command is determined to be the first charging mode.

[0053] In an optional embodiment of the present invention, a user can determine a charging mode based on their travel needs and send a selection command to the vehicle system via a mobile terminal. The app installed on the terminal includes a function introduction and guidance, which the user can use to decide which charging mode to choose based on their needs.

[0054] Optionally, one of the multiple charging modes is designated as the first charging mode, including:

[0055] The preset mode among the plurality of charging modes is determined as the first charging mode.

[0056] In an optional embodiment of the present invention, the plurality of charging modes includes a preset mode, which is a default charging mode. The default state refers to the charging mode adopted by the vehicle system when the user has not issued the mode selection command. Once the vehicle system receives the mode selection command, the preset mode is automatically turned off.

[0057] Optionally, the charging control method further includes:

[0058] The system obtains mode setting operations input by the user on the mode setting interface; wherein the mode setting operations include setting one or more of the following: determining the charging upper limit based on the vehicle's travel status and battery characteristics, setting the charging upper limit by the user, setting the charging power by the user, setting whether to enable the constant temperature protection setting by the user, and setting whether to enable the battery heating setting during the trip.

[0059] The preset mode is generated according to the mode setting operation.

[0060] In an optional embodiment of the present invention, the various settings in the preset mode can be completed through the mode setting operation. During the mode setting operation, the user can set one or more of the following: charging upper limit, charging power, constant temperature protection setting, and battery heating setting during operation. One range of the charging upper limit is 60%. ～ The charging limit can be set manually by the user or selected by the system settings. The system will select an appropriate charging limit based on the battery status and learned user travel habits. The constant temperature protection function can be set to be on or off by the user. The battery in-flight heating function can be set to be on or off by the user.

[0061] In an optional embodiment of the present invention, the user can set the function according to their own needs, so that the car charging mode is adjusted to a state that is more suitable for travel needs.

[0062] Optionally, in the first charging mode, the ratio between the upper limit of charging and the total charge of the power battery is within a first preset range; wherein, the method further includes one or more of the following:

[0063] The charging power of the first charging mode is determined based on the charging rules and policies sent by the cloud server.

[0064] Based on the user's settings for the constant temperature protection function, determine the constant temperature protection settings for the first charging mode.

[0065] Based on the user's settings for the battery heating function during charging, the battery heating settings for the first charging mode are determined.

[0066] In one of the optional embodiments of the present invention, the applicable scenario is daily commuting. One of the first preset ranges is 80% to 90%, and the system will plan the charging limit based on travel distance habits and battery characteristics to ensure travel distance and charging speed while extending battery life.

[0067] Optionally, in the first charging mode, the charging upper limit is equal to the total charging capacity of the power battery, and the charging power of the power battery is a set standard charging power value; wherein, the method further includes one or more of the following:

[0068] The constant temperature protection setting for the first charging mode is set to enable the constant temperature protection function.

[0069] The battery in-process heating in the first charging mode is set to be enabled before charging.

[0070] In an optional embodiment of the present invention, one applicable scenario is long-distance travel, which includes trips exceeding 100km. When the in-trip heating function is activated, the vehicle system, combining navigation, vehicle status, and user driving habits, plans to preheat the battery before charging. This prepares the battery for charging in advance, significantly improving charging efficiency and shortening charging time. Simultaneously, the charging limit is equivalent to the total charge capacity of the power battery, ensuring driving range and providing users with a superior travel experience.

[0071] Optionally, in the first charging mode, the ratio between the upper limit of charging and the total charge of the power battery is within a second preset range; wherein, the method further includes one or more of the following:

[0072] The charging power of the first charging mode is determined based on the charging rules and policies sent by the cloud server.

[0073] The temperature protection setting for the first charging mode is set to enable the temperature protection function.

[0074] In one of the optional embodiments of the present invention, this embodiment is applicable to long-term storage. One of the second preset ranges is less than 80%. When the car is stored, the system will monitor and manage the power battery in real time. Through high-voltage discharge or thermal management on the vehicle, the power battery is kept in a suitable charge range and temperature range, thereby protecting the battery and extending its service life.

[0075] An optional embodiment of the present invention provides an optional charging control method before determining that one of a plurality of charging modes is the first charging mode. See also Figure 2 , Figure 2 This is a flowchart of the charging control method provided in this optional embodiment, such as... Figure 2 As shown, before determining one of the multiple charging modes as the first charging mode, the method further includes:

[0076] Step 201: If the power battery is not in the driving state for a first preset time, a notification message is sent to the user to keep the vehicle plugged in.

[0077] In this step, the first preset duration includes a case of setting it to 3 days. When the car is not in motion, it is recommended to keep the charging gun plugged in. When plugged in, the system will monitor and manage the power battery in real time. Through high-voltage discharge or thermal management on the vehicle, the power battery will be kept in a suitable charge range and temperature range, and will automatically charge to the upper limit before driving.

[0078] Step 202: If the vehicle is found to have maintained the charging gun state for a second preset time, a mode adjustment command request is sent to the user, prompting the user to input a mode selection command and select the first charging mode.

[0079] In this step, the second preset duration includes a case where it is set to 3 days. When the charging gun is kept plugged in for the second preset duration, the car system sends a mode adjustment command request to the user's mobile terminal APP, reminding the user to enter a mode selection command so that the system can use the appropriate charging mode for charging.

[0080] In an optional embodiment of the present invention, the vehicle system monitors the duration of time the user does not use the vehicle. If a preset time is reached, the system sends the mode adjustment command request to the user to remind the user to adjust the mode. This allows the vehicle system to enter a suitable charging mode in a timely manner, which is beneficial for the long-term use of the battery and improves battery life.

[0081] Optional embodiments of the present invention provide optional further charging control methods. See also Figure 3 , Figure 3 This is a flowchart of the charging control method provided in this optional embodiment, such as... Figure 3 As shown, the method further includes:

[0082] Step 301: If the power battery is detected to enter the driving state, the current first charging mode is switched to the second charging mode; wherein, the second charging mode is one of the multiple charging modes, and the second charging mode is the charging mode of the power battery before it was switched to the first charging mode.

[0083] Step 302: Charge the power battery according to the second charging mode.

[0084] In an optional embodiment of the present invention, after the charging mode is switched, the vehicle system sends a message to the user's mobile terminal APP to inform the user that the mode switch has been performed. This achieves automatic switching after detecting the user's travel status, which helps the vehicle quickly adjust its state to meet travel needs and improves the user's travel experience.
