[0068] Exemplary embodiments will now be described in detail, examples of which are illustrated in the accompanying drawings. When the following description relates to the drawings, unless otherwise indicated, the same numerals in different drawings denote the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with this disclosure.

[0070] It should be understood that although the terms first, second, third, etc., may be used in this disclosure to describe various information, such information should not be limited to these terms. These terms are used only to distinguish information of the same type from one another. For example, without departing from the scope of this disclosure, first information may also be referred to as second information, and similarly, second information may also be referred to as first information. Depending on the context, the word "if" as used herein may be interpreted as "when," "when," or "in response to determination."

[0071] The method described in this disclosure is applied to a vehicle controller, wherein the vehicle controller can be installed in the central control system of the vehicle, or it can be installed as a new controller in the control component of the engine management system (EMS).

[0072] Figure 1 A flowchart illustrating a vehicle charging control method according to an exemplary embodiment of this disclosure is shown.

[0073] In step S101, the vehicle's driving status information is obtained.

[0074] The vehicle's driving status information can be operational data generated during vehicle operation, or the vehicle's average driving status over a certain period of time, representing the user's driving habits or vehicle usage status within a set time period. The set time period can be configured according to actual needs, such as the past week. For example, the driving status information may include the vehicle's usage time intervals or the vehicle's navigation routes.

[0075] In step S102, based on the vehicle's driving status information, the engine control system (EMS) is controlled to adjust the state of charge (SOC) balance point of the vehicle battery.

[0076] The engine control system (EMS) can be used to adjust the state of charge (SOC) of the vehicle battery. Additionally, it can control the vehicle alternator to charge the vehicle battery. The vehicle battery can be a starting battery, primarily used to power the engine and other electrical appliances within the vehicle. Based on the driving status information obtained in the preceding steps, the user's vehicle usage status can be acquired, allowing the EMS to adjust the vehicle battery's SOC accordingly.

[0077] In step S103, the EMS is controlled to charge the vehicle battery according to the SOC balance point.

[0078] State of Charge (SOC) refers to the remaining charge of a vehicle battery, while the SOC balance point represents a control parameter for the SOC. The EMS (Electrical Maintenance System) can control the vehicle battery to charge according to the SOC balance point, maintaining the remaining charge at a value determined by the SOC balance point. Specifically, the charging process can begin after the vehicle is started, controlled by the EMS, based on the SOC balance point.

[0079] The method described in this disclosure adjusts the state of charge (SOC) balance point of the vehicle battery and charges it by using the vehicle's driving status information, so that the SOC balance point of the vehicle battery is related to the user's vehicle usage status, thereby improving the vehicle's fuel economy and vehicle battery safety.

[0080] In some embodiments, the vehicle's driving status information may include the vehicle's usage time interval. Specifically, the vehicle's usage time interval can be determined by self-learning the vehicle's usage frequency within a preset time period using a timing chip inside the vehicle's transmitter; that is, the user's average recent usage frequency of the vehicle. Then, based on the length of the vehicle's usage time interval, the EMS can be controlled to adjust different SOC balance points. The specific SOC balance point adjustment methods can be divided into the following three cases:

[0081] In the first scenario, in response to the vehicle's usage time interval being less than a first time threshold, the EMS is controlled to adjust the SOC balance point of the vehicle battery to a first balance point, which is lower than the vehicle battery's factory default balance point.

[0082] The first time threshold can be set according to actual needs, such as 24 hours (one day). When the usage time interval is less than the first time threshold, indicating frequent use by the current user, the SOC balance point of the vehicle battery can be lowered from the factory default balance point to the first balance point, for example, setting the remaining charge of the vehicle battery to 60%. This reduces the amount of charge stored in the vehicle battery during driving, preventing the alternator from frequently generating electricity to store excess energy in the battery. This reduces excessive heat and safety hazards caused by a high SOC balance point during vehicle use, further improving fuel economy. Furthermore, since the vehicle is currently in a state of frequent use, the engine will not fail to start due to prolonged battery discharge caused by long-term parking.

[0083] In the second scenario, in response to the vehicle's usage time interval being greater than or equal to the first time threshold and less than the second time threshold, the EMS is controlled to adjust the vehicle battery's SOC balance point to a second balance point, which is higher than the first balance point and lower than the vehicle battery's factory default balance point.

[0084] Similarly, the second time threshold can be set according to actual needs, such as 168 hours (one week). When the usage interval is between the first and second time thresholds, it indicates that the current user's vehicle usage frequency is normal. That is, compared to frequent usage scenarios, the vehicle's usage interval is relatively long. The SOC balance point of the vehicle battery can be appropriately increased, for example, from 60% (first balance point) to 80% (second balance point). While ensuring vehicle fuel economy, this reduces the possibility of battery depletion due to prolonged vehicle parking, ensuring that the vehicle battery has sufficient charge to support normal vehicle starting.

[0085] In the third case, in response to the vehicle's usage time interval being greater than or equal to the second time threshold, the EMS is controlled to adjust the SOC balance point of the vehicle battery to the factory default balance point of the vehicle battery.

[0086] When the usage time interval exceeds the second time threshold, it indicates that the current user does not use the vehicle frequently. The EMS can be controlled to adjust the SOC balance point of the vehicle battery to the factory default balance point of the vehicle battery, such as 90%, to prevent the vehicle battery from continuously discharging to a depleted state due to long-term parking, and to ensure that the user can start the vehicle normally the next time they use it.

[0087] The method described in this disclosure determines different SOC balance points based on the length of the vehicle's usage time interval, so that the SOC balance point of the vehicle battery is correlated with the user's vehicle usage frequency, thereby improving the vehicle's fuel economy and vehicle battery safety.

[0088] After determining the SOC balance point of the vehicle battery by the vehicle's usage time interval according to the above steps, this disclosure further provides two preferred embodiments for step 103 to improve the health of the vehicle battery.

[0089] The first implementation example Figure 2 As shown, the specific steps include S103a to S103c.

[0090] In step S103a, in response to the fact that the vehicle battery charge has not reached a preset state during the first number of driving cycles of the vehicle, the State of Health (SOH) of the vehicle battery is obtained.

[0091] The preset state can represent, for example, that the vehicle battery is fully charged or has been charged to a set percentage, such as 90%. If the vehicle battery fails to reach full charge after multiple consecutive charging cycles, common vehicle batteries, such as lead-acid batteries, are prone to sulfation, leading to a decrease in battery capacity and lifespan. Therefore, in an optional embodiment, if the vehicle battery is not in the preset state during the first number of driving cycles (e.g., 5 cycles), the State of Harm (SOH) of the vehicle battery is obtained. The SOH of the vehicle battery can be acquired through a battery sensor connected to the EMS via a Serial Communication System (LIN bus) to monitor the SOC, health, and charging efficiency of the vehicle battery.

[0092] In step S103b, if the SOH of the vehicle battery meets the first preset condition, in response to the fact that the vehicle battery charge does not reach the preset state during the second number of driving cycles of the vehicle, the EMS is controlled to charge the vehicle battery to a full charge state, wherein the second number is greater than the first number.

[0093] The first preset condition indicates that the state of harmlessness (SOH) of the vehicle battery is good. If the battery charge has not reached the preset state after the vehicle has gone through a second number of driving cycles (e.g., 10 times), the EMS can be controlled to fully charge the vehicle battery to ensure that the vehicle battery is fully charged at least once after the first number plus the second number of driving cycles, thus maintaining the SOH of the vehicle battery.

[0094] In step S103c, if the SOH of the vehicle battery does not meet the first preset condition, the EMS is controlled to charge the vehicle battery to full charge.

[0095] If the first condition is not met, it indicates that the SOH of the vehicle battery is poor, and the battery can be fully charged to ensure that the battery capacity will not decrease due to long-term undercharging.

[0096] In the above steps, the full charge can be performed in multiple charging processes to further ensure the SOH of the vehicle battery.

[0097] In the above embodiments, the vehicle battery is fully charged based on its battery health status to ensure its health and extend its service life.

[0098] The second implementation example Figure 3 As shown, the specific steps include S103A to S103D.

[0099] In step S103A, in response to the vehicle entering the parking state, the maximum power consumption time of the vehicle is determined according to the SOC state of the vehicle battery. The maximum power consumption time represents the time required for the vehicle battery to be depleted to a low-charge state. The low-charge state represents that the remaining power of the current battery is less than the SOC balance point of the vehicle battery. The low-charge state is likely to cause the battery power to be insufficient to provide enough power for engine starting.

[0100] When the vehicle is parked, the remaining charge in the vehicle battery can be determined based on the SOC state of the vehicle battery. Based on the remaining charge, the time interval required for the vehicle battery to deplete to a low charge state can be determined, i.e., the maximum charge consumption time.

[0101] In step S103B, a first prompt message is sent, which is used to prompt the user about the maximum power consumption time.

[0102] The vehicle's entertainment system host controller (HU) can play voice or text prompts to remind the user of the maximum battery consumption time. The HU is connected to the EMS via a controller area network (CAN bus).

[0103] In step S103C, in response to the fact that the parking time and maximum consumption time of the vehicle do not meet the set conditions, a second prompt message is sent. The second prompt message is used to prompt the user to choose whether to charge the vehicle battery.

[0104] If the set conditions are not met, it indicates that the vehicle's stopping time is approaching the time when the vehicle battery is about to run out of power. The second prompt message can be sent to the user. For example, a pop-up message can be sent to the associated APP of the user terminal device through the vehicle's telematics system T-BOX to prompt the user that the vehicle battery is about to run out of power and ask the user whether to charge the vehicle battery. The T-BOX and EMS are connected through the controller area network (CAN line).

[0105] In step S103D, upon receiving a user charging command, the EMS is controlled to charge the vehicle battery according to the SOC balance point.

[0106] If the user selects to start charging, the EMS can be remotely controlled to charge the vehicle battery and update the vehicle's usage time interval. If the usage time interval is close to the maximum power consumption time again, the second prompt message will be sent to the user again.

[0107] Furthermore, in the absence of a user charging instruction, the low-charge state of the vehicle battery can be obtained. In one example, the low-charge state can be determined by using the battery sensor to determine the relationship between the remaining charge of the vehicle battery and the vehicle battery's SOC balance point. In response to the low-charge state of the vehicle battery, the charging efficiency of the vehicle battery is obtained, and the EMS is controlled to charge the vehicle battery based on the charging efficiency.

[0108] Specifically, when the charging efficiency of the vehicle battery is greater than or equal to a preset efficiency threshold, it indicates that the current charging efficiency of the vehicle battery is high. The EMS can control the vehicle battery to be charged to full charge multiple times in a first charging cycle. When the charging efficiency of the vehicle battery is less than the preset efficiency threshold, it indicates that the current charging efficiency of the vehicle battery is low. The EMS can control the vehicle battery to be charged to full charge multiple times in a second charging cycle. The second charging cycle is greater than the first charging cycle. That is, the higher the charging efficiency, the fewer the number of full charge cycles are required. This is to repair the battery that has experienced a low charge and restore the state of charge (SOH) of the vehicle battery.

[0109] In the above embodiments, prompts are used to encourage users to charge the vehicle battery promptly, preventing it from becoming depleted due to prolonged parking. Furthermore, if the vehicle battery is already depleted, it is fully charged according to preset rules, improving battery health and extending its lifespan.

[0110] In other embodiments, the vehicle's driving status information includes the vehicle's navigation route, which allows the EMS to determine different SOC balance points based on the planned distance of the navigation route. The specific steps are as follows:

[0111] First, based on the vehicle's current navigation route, determine the planned distance between the vehicle's starting point and ending point.

[0112] Furthermore, in response to the planned distance being greater than a first distance threshold, indicating that the vehicle is about to embark on a long-distance journey, if the planned distance to be traveled is greater than a second distance threshold, the SOC of the vehicle battery can be controlled to a third balance point, which is lower than the factory default balance point of the vehicle battery; if the planned distance to be traveled is less than or equal to the second distance threshold, the SOC balance point of the vehicle battery can be controlled to a fourth balance point via EMS, which is higher than the third balance point and lower than the factory default balance point of the vehicle battery.

[0113] Specifically, such as Figure 4 As shown, the second distance threshold indicates that the vehicle is about to reach its destination. When the distance to be traveled is greater than the second distance threshold, the SOC balance point of the vehicle battery can be lowered from the factory default balance point to the third balance point through EMS. This reduces the amount of electricity stored in the vehicle battery during vehicle operation, so that the generator will not frequently generate electricity to store excess energy in the vehicle battery, thereby further improving the vehicle's fuel economy.

[0114] The second distance threshold can be set as 10% of the total planned distance. When the distance to be traveled is less than the second distance threshold, it indicates that the user is about to reach the destination, and the SOC balance point of the vehicle battery can be appropriately adjusted to the fourth balance point via EMS. Since the destination is usually in an unfamiliar environment during long-distance travel, to further avoid the occurrence of battery depletion, the SOC balance point can be appropriately increased. This reduces the possibility of battery depletion due to prolonged parking while ensuring vehicle fuel economy, ensuring that the vehicle battery has sufficient charge to support normal vehicle starting, and avoiding inconvenience caused by the vehicle failing to start during the return trip.

[0115] Preferably, the average driving distance between frequently used user locations determined by the vehicle's historical navigation routes can be used as the first distance threshold, wherein the frequently used locations are determined based on the start and end locations set by the user within a preset time period.

[0116] Specifically, based on the user's recent travel history, destination settings, and other information, the system can learn the user's frequently used locations and average driving distances, such as the user's commuting distance and daily shopping distance. If the planned distance exceeds the user's average driving distance, it indicates that the user is about to undertake a long-distance trip and the destination is not a frequently used location. In this case, the above method can be used to adjust the SOC balance point of the vehicle battery via EMS.

[0117] Furthermore, a third distance threshold can be set for the ultra-long-distance driving distance. If the planned distance is greater than or equal to the third distance threshold, it indicates that the user is about to undertake an ultra-long-distance trip, such as continuous inter-provincial driving. If the vehicle's expected driving distance is greater than the first distance threshold, the EMS can be controlled to adjust the vehicle battery's SOC balance point to the third balance point to improve the vehicle's fuel economy. If the vehicle's expected driving distance is less than or equal to the first distance threshold, the EMS can be controlled to adjust the vehicle battery's SOC balance point to the vehicle battery's factory default balance point, so that the vehicle battery stores as much charge as possible and avoids battery depletion due to prolonged parking in unfamiliar environments.

[0118] The method described in this disclosure determines different SOC balance points based on the planned distance of the vehicle navigation route, so that the SOC balance point of the vehicle battery is correlated with the user's travel plan and driving progress, thereby improving the vehicle's fuel economy and vehicle battery safety.

[0119] For the foregoing method embodiments, in order to simplify the description, they are all described as a series of actions. However, those skilled in the art should know that this disclosure is not limited to the described order of actions, because according to this disclosure, some steps may be performed in other orders or simultaneously.

When the status adjustment module controls the engine control system (EMS) to adjust the vehicle battery's state of charge (SOC) balance point based on the vehicle's driving status information, it is specifically used for:

[0127] In response to the vehicle's usage time interval being less than a first time threshold, the EMS is controlled to adjust the SOC balance point of the vehicle battery to a first balance point, which is lower than the vehicle battery's factory default balance point.
