[0047] Hereinafter, various exemplary embodiments of the present invention will be described in detail with reference to Figures 1 to 6 FIG.

[0048] Figure 1 is a block diagram showing a vehicle control device according to an exemplary embodiment of the present invention.

[0049] According to an exemplary embodiment of the present invention, the vehicle control device 100 may include a processor 110 and a memory 120. Figure 1 The components of the vehicle control device 100 shown are merely illustrative, and the embodiments of the present invention are not limited thereto. For example, the vehicle control device 100 may further include components not shown in Figure 1 FIG.

[0050] According to an exemplary embodiment of the present invention, the memory 120 may store commands or data. For example, the memory 120 may store one instruction or two or more instructions that, when executed by the processor 110, cause the vehicle control device 100 to perform various operations.

[0051] According to an exemplary embodiment of the present invention, the memory 120 may include non-volatile memory (e.g., read-only memory (ROM)) and volatile memory (e.g., random access memory (RAM)).

[0052] According to an exemplary embodiment of the present invention, the memory 120 and the processor 110 may be implemented as a chipset and may store various information associated with the vehicle control device 100. For example, the memory 120 may store information related to the operation history of the processor 110. As a detailed example, such information may include the state of health (SOH) of each vehicle model determined by evaluating the durability of the battery of each vehicle model in the memory 120, conditions for heating the coolant, conditions for cooling the coolant, and the like.

[0053] According to an exemplary embodiment of the present invention, the processor 110 may obtain a reference SOH for each vehicle model determined by evaluating the durability of the battery of each vehicle model, may identify which vehicle model's battery the battery of the present vehicle corresponds to, may identify the reference SOH of the present vehicle corresponding to the battery of the present vehicle among the reference SOHs of each vehicle model, and may be configured to control at least one of the temperature of the battery, the output of the battery, or any combination thereof based on identifying that the SOH of the battery of the present vehicle is less than the reference SOH of the present vehicle.

[0054] According to an exemplary embodiment of the present invention, the SOH for each vehicle model may be determined by evaluating the durability of the battery of each vehicle model. For example, the SOH for each vehicle model may include a standard SOH established by evaluating the durability of the battery system according to the vehicle model.

[0055] For example, the SOH for each vehicle model may include information related to the cumulative driving distance of the present vehicle, the duration of use of the battery, or the degree to which the SOH decreases according to the life cycle of the battery. Herein, the life cycle of the battery may be the number of times the battery is charged to its total capacity, and one cycle may mean that a discharged battery is fully charged to 100%.

[0056] For example, the SOH for each vehicle model may include information related to the degree of average decrease in the SOH of the battery according to the vehicle model.

[0057] As a detailed example, the SOH for each vehicle model may include information related to the degree to which the SOH of the battery decreases as the cumulative driving distance of the present vehicle of each vehicle model increases. In addition, the SOH for each vehicle model may include the degree to which the SOH of the battery decreases as the duration of using the battery increases. In addition, the SOH for each vehicle model may include information related to the degree to which the SOH of the battery decreases as the life cycle of the battery increases.

[0058] For example, the SOH for each vehicle model may be determined by evaluating the durability of the battery, which is performed during the process of developing a battery management system (BMS) for each vehicle model.

[0059] For example, the SOH for each vehicle model may be provided from an external server and stored in the memory 120. In addition, the SOH for each vehicle model may be updated by the system or the user.

[0060] According to an exemplary embodiment of the present invention, the processor 110 may monitor the SOH of the battery and may compare the reference SOH corresponding to the present vehicle among the SOHs of each vehicle model with the SOH of the battery of the present vehicle.

[0061] For example, the processor 110 may be configured to determine or predict the SOH of the vehicle battery based on at least one of the charging capacity during battery charging, the charging energy during battery charging, the voltage drop of each output of the battery when the vehicle is running, or the discharge energy of the battery, or any combination thereof.

[0062] For example, the processor 110 may monitor the SOH of the vehicle battery and may correspond the current SOH of the vehicle battery to the SOH of each vehicle model according to the cumulative driving distance of the vehicle, the usage duration of the vehicle battery, the life cycle of the vehicle battery, etc. The processor 110 may identify the SOH of each vehicle model corresponding to the current SOH of the vehicle battery among the SOH of each vehicle model as the "reference SOH of the vehicle".

[0063] For example, the processor 110 may set the reference SOH of the vehicle according to any one of the cumulative driving distance of the vehicle, the usage duration of the battery, or the life cycle of the battery.

[0064] As a detailed example, the processor 110 may identify the SOH corresponding to the current cumulative driving distance of the vehicle among the SOH of each vehicle model as the reference SOH of the vehicle, and may compare the current SOH of the vehicle battery with the reference SOH of the vehicle. As an exemplary embodiment of the present invention, the processor 110 may use the SOH corresponding to the usage duration of the vehicle battery so far among the SOH of each vehicle model as the reference SOH of the vehicle, and may compare the current SOH of the vehicle battery with the reference SOH of the vehicle. As an exemplary embodiment of the present invention, the processor 110 may identify the SOH corresponding to the current life cycle of the vehicle battery among the SOH of each vehicle model as the reference SOH of the vehicle, and may compare the current SOH of the vehicle battery with the reference SOH of the vehicle.

[0065] According to an exemplary embodiment of the present invention, the processor 110 may compare the reference SOH of the vehicle with the SOH of the vehicle battery always or during a certain period of time. For example, the processor 110 may be configured to compare the reference SOH of the vehicle with the SOH of the vehicle battery for each specific cumulative driving distance, or may be configured to compare the reference SOH of the vehicle and the SOH of the vehicle battery for each specific life cycle.

[0066] According to an exemplary embodiment of the present invention, when the SOH of the vehicle battery is less than the reference SOH of the vehicle corresponding to the vehicle, the processor 110 may be configured to control at least one of the temperature of the battery, the output of the battery, or any combination thereof.

[0067] For example, when the SOH of the vehicle battery is less than the reference SOH of the vehicle corresponding to the vehicle, the processor 110 may be configured to determine that the durability of the vehicle battery has decreased more than the average durability of the battery corresponding to the vehicle model. In this case, the processor 110 may be configured to determine that the battery of the vehicle needs to be managed to be optimized.

[0068] According to an exemplary embodiment of the present invention, when the SOH of the vehicle battery is less than the reference SOH of the vehicle corresponding to the vehicle, the processor 110 may be configured to control the temperature of the vehicle battery using a coolant so that the temperature of the vehicle battery is maintained within an appropriate temperature range.

[0069] For example, when the temperature of the vehicle battery is a low temperature deviated from the appropriate temperature range, the processor 110 may heat the coolant to increase the temperature of the battery.

[0070] For example, when the temperature of the vehicle battery is a high temperature deviated from the appropriate temperature range, the processor 110 may cool the coolant to reduce the temperature of the battery.

[0071] According to an exemplary embodiment of the present invention, when the SOH of the vehicle battery is less than the reference SOH of the vehicle corresponding to the vehicle, the processor 110 may be configured to control the output of the battery so that the burden on the SOH of the battery caused by the output of the battery during the vehicle's travel can be reduced.

[0072] For example, when the SOH of the vehicle battery is less than the reference SOH of the vehicle corresponding to the vehicle, the processor 110 may reduce the output of the battery according to the vehicle's travel. As a detailed example, when the SOH of the vehicle is less than the reference SOH of the vehicle, the processor 110 may reduce the magnitude of the output of the battery according to the acceleration of the vehicle, reduce the magnitude of the output of the battery according to the deceleration of the vehicle, or reduce the magnitude of the maximum output of the battery according to the vehicle's travel.

[0073] For example, compared with the output map of the battery when the SOH of the vehicle is greater than or equal to the reference SOH of the vehicle, when the SOH of the vehicle is less than the reference SOH of the vehicle, the processor 110 may reduce the output of the battery.

[0074] According to an exemplary embodiment of the present invention, the processor 110 may be configured to, in a state where the vehicle is traveling, based on identifying that the degree to which the SOH of the vehicle battery is less than the reference SOH of the vehicle is less than a predetermined difference and identifying that the temperature of the battery is less than a first temperature including a low temperature at which the battery performance deteriorates, control the coolant according to a first heating condition to increase the temperature of the battery.

[0075] For example, a predetermined difference can be set to the following value: it is used to divide the number of times or methods for controlling the temperature of the battery or the number of times or methods for controlling the output of the battery to optimize the SOH of the vehicle battery.

[0076] For example, when the difference between the SOH of the vehicle battery and the reference SOH of the vehicle is less than a predetermined value, even if the number of times of controlling the temperature, output, etc. of the battery is small, the processor 110 can optimize the SOH of the battery. On the other hand, when the difference between the SOH of the vehicle battery and the reference SOH of the vehicle is greater than a predetermined value, the processor 110 may require a relatively large amount of time to control the temperature, output, etc. of the battery to optimize the SOH of the battery.

[0077] As a detailed example, when the degree to which the SOH of the vehicle battery is less than the reference SOH of the vehicle is less than a predetermined difference, the processor 110 can set the number of times of outputting the temperature, output, etc. of the battery to one time. When the degree to which the SOH of the vehicle battery is less than the reference SOH of the vehicle is greater than or equal to the predetermined difference, the processor 110 can set the number of times of outputting the temperature, output, etc. of the battery to two or more times.

[0078] According to an exemplary embodiment of the present invention, the processor 110 can identify whether the temperature of the vehicle battery is lower than a first temperature when the vehicle is in a driving state. Herein, the first temperature can include a low temperature that deteriorates the battery performance. As a detailed example, the first temperature can be set to 10 degrees Celsius. The first temperature can be set differently according to the driving environment or system settings.

[0079] For example, when it is identified that the temperature of the vehicle battery is lower than the first temperature when the vehicle is in a driving state, the processor 110 can be configured to determine that there is a risk that the battery performance may deteriorate. When the vehicle continues to drive in a state where the temperature of the vehicle battery is lower than the first temperature, the processor 110 can be configured to determine that it affects the SOH of the battery.

[0080] According to an exemplary embodiment of the present invention, the processor 110 can be configured to control the coolant of the vehicle according to a first heating condition or a second heating condition to increase the temperature of the battery. Herein, the coolant can include a coolant for cooling the battery or heating the battery.

[0081] For example, the first heating condition and the second heating condition may include at least one of the time for heating the coolant, the number of times of heating the coolant, the temperature of the heated coolant, the flow rate of the coolant, or the flow velocity of the coolant, or any combination thereof. As an exemplary embodiment of the present invention, even if the heating temperature of the coolant included in the first heating condition is the same as the heating temperature of the coolant included in the second heating condition, the first heating condition and the second heating condition can be divided by making the number of times or the time of heating the coolant included in the first heating condition different from the number of times and the time of heating the coolant included in the second heating condition.

[0082] According to an exemplary embodiment of the present invention, the number of daily operations under the first heating condition and the number of daily operations under the second heating condition can be set differently. According to an exemplary embodiment of the present invention, the number of daily operations under the first heating condition can be set to be less than the number of daily operations under the second heating condition.

[0083] As a detailed example, when the difference between the SOH of the vehicle battery and the reference SOH of the vehicle is 3% for a predetermined difference, and when the first temperature is 10 degrees Celsius, the processor 110 can increase the temperature of the battery according to the first heating condition as follows.

[0084] When it is recognized that the degree to which the SOH of the vehicle battery is less than the reference SOH of the vehicle is less than 3%, and when the temperature of the battery is measured to be less than 10 degrees Celsius while the vehicle is in motion, the processor 110 can increase the temperature of the battery according to the first heating condition for heating the coolant, once per hour and at most once a day, until the temperature of the battery reaches 10 degrees Celsius.

[0085] According to an exemplary embodiment of the present invention, the processor 110 can be configured to control the coolant to increase the temperature of the battery according to the second heating condition based on recognizing that, while the vehicle is in motion, the degree to which the SOH of the vehicle battery is less than the reference SOH of the vehicle is greater than or equal to a predetermined difference and recognizing that the temperature of the battery is less than the first temperature.

[0086] For example, when the degree to which the SOH of the vehicle battery is less than the reference SOH of the vehicle is greater than or equal to a predetermined difference, the processor 110 can increase the temperature of the battery according to the second heating condition to heat the coolant faster than the first heating condition or for a longer time than the first heating condition.

[0087] As an exemplary embodiment of the present invention, although the control associated with the coolant included in the first heating condition and the control associated with the coolant included in the second heating condition are the same as each other, the processor 110 may set the number of daily operations under the second heating condition to be greater than the number of daily operations under the first heating condition, and may distinguish the control according to the first heating condition and the control according to the second heating condition.

[0088] As a detailed example, when the difference between the SOH of the vehicle battery and the reference SOH of the vehicle is a predetermined difference of 3%, and when the first temperature is 10 degrees Celsius, the processor 110 may increase the temperature of the battery according to the second heating condition as follows.

[0089] When it is recognized that the degree to which the SOH of the vehicle battery is less than the reference SOH of the vehicle is less than 3%, and when the temperature of the battery is measured to be less than 10 degrees Celsius while the vehicle is in a driving state, the processor 110 may increase the temperature of the battery up to twice a day, once an hour, according to the second heating condition for heating the coolant until the temperature of the battery reaches 10 degrees Celsius.

[0090] According to an exemplary embodiment of the present invention, the processor 110 may be configured to control the coolant based on recognizing that, while the vehicle is in a driving state, the SOH of the battery is less than the reference SOH of the vehicle by less than a predetermined difference and recognizing that the temperature of the battery is greater than a second temperature including a high temperature that deteriorates battery performance, according to the first cooling condition to reduce the temperature of the battery.

[0091] According to an exemplary embodiment of the present invention, the processor 110 may recognize whether the temperature of the vehicle battery is greater than a second temperature while the vehicle is in a driving state. Herein, the second temperature may include a high temperature that deteriorates battery performance. As a detailed example, the second temperature may be set to 40 degrees Celsius. The second temperature may be set differently according to the driving environment or system settings.

[0092] For example, when it is recognized that the temperature of the vehicle battery is greater than the second temperature while the vehicle is in a driving state, the processor 110 may be configured to determine that there is a risk that battery performance may deteriorate. When the vehicle continues to drive in a state where the temperature of the vehicle battery is greater than the second temperature, the processor 110 may be configured to determine that it affects the SOH of the battery.

[0093] According to an exemplary embodiment of the present invention, the processor 110 may be configured to control the coolant of the vehicle according to the first cooling condition or the second cooling condition to reduce the temperature of the battery.

[0094] For example, the first cooling condition and the second cooling condition may include at least one of the time for cooling the coolant, the number of times of cooling the coolant, the temperature for cooling the coolant, the instantaneous cooling performance, or the time for maintaining the coolant, or any combination thereof.

[0095] According to an exemplary embodiment of the present invention, the instantaneous cooling performance may include the performance for improving the instantaneous output of the coolant. For example, the instantaneous cooling performance may be determined based on at least one of the degree of increase in the flow rate of the coolant or the degree of increase in the flow velocity of the coolant, or any combination thereof. As a detailed example, the processor 110 may increase the flow rate of the coolant flowing through the same cross-sectional area, or may increase the flow velocity of the coolant, to improve the instantaneous cooling performance.

[0096] According to an exemplary embodiment of the present invention, even if the instantaneous cooling performance included in the first cooling condition and the instantaneous cooling performance included in the second cooling condition are the same as each other, the first cooling condition and the second cooling condition may be divided by making the time for maintaining the coolant included in the first cooling condition and the time for maintaining the coolant included in the second cooling condition different from each other. The first cooling condition and the second cooling condition may be conditions applied in a state where the vehicle is traveling.

[0097] As a detailed example, when the predetermined difference is 3% for the difference between the SOH of the vehicle battery and the reference SOH of the vehicle, and when the second temperature is 40 degrees Celsius, the processor 110 may lower the temperature of the battery according to the first cooling condition as follows.

[0098] When it is recognized that the degree to which the SOH of the vehicle battery is less than the reference SOH of the vehicle is less than 3%, and when the temperature of the battery is measured to be greater than 40 degrees Celsius in a state where the vehicle is traveling, the processor 110 may lower the temperature of the battery according to the first cooling condition to continuously improve the instantaneous output performance of the coolant for 30 minutes until the temperature of the battery is 30 degrees Celsius.

[0099] According to an exemplary embodiment of the present invention, the processor 110 may be configured to control the coolant to lower the temperature of the battery according to the second cooling condition based on recognizing that the degree to which the SOH of the battery is less than the reference SOH of the vehicle is greater than or equal to the predetermined difference and recognizing that the temperature of the battery is greater than the second temperature in a state where the vehicle is traveling.

[0100] As a detailed example, when the predetermined difference is 3% for the difference between the SOH of the vehicle battery and the reference SOH of the vehicle, and when the second temperature is 40 degrees Celsius, the processor 110 may lower the temperature of the battery according to the second cooling condition as follows.

[0101] When it is recognized that the degree to which the SOH of the battery of the present vehicle is less than the reference SOH of the present vehicle is greater than or equal to 3%, and when the temperature of the battery is measured to be greater than 40 degrees Celsius while the vehicle is in a driving state, the processor 110 may reduce the temperature of the battery according to the second heating condition, increasing the instantaneous output of the coolant by one hour each time until the temperature of the battery reaches 30 degrees Celsius.

[0102] According to an exemplary embodiment of the present invention, the processor 110 may be configured to control the coolant to reduce the temperature of the battery according to a third cooling condition based on recognizing that the degree to which the SOH of the battery is less than the reference SOH of the present vehicle is less than a predetermined difference and recognizing that the temperature of the battery is greater than a second temperature including a high temperature that deteriorates battery performance while the vehicle is not in a driving state.

[0103] According to an exemplary embodiment of the present invention, the processor 110 may be configured to control the coolant of the present vehicle to reduce the temperature of the battery according to a third cooling condition or a fourth cooling condition while the vehicle is not in a driving state.

[0104] For example, the third cooling condition and the fourth cooling condition may include at least one of the time for cooling the coolant, the number of times for cooling the coolant, the temperature for cooling the coolant, the instantaneous cooling performance, or the time for maintaining the coolant or any combination thereof. As an exemplary embodiment of the present invention, although the temperature for cooling the coolant included in the third cooling condition and the temperature for cooling the coolant included in the fourth cooling condition are the same as each other, the third cooling condition and the fourth cooling condition may also be divided by making the number of times or the time for cooling the coolant included in the third cooling condition different from the number of times or the time for cooling the coolant included in the fourth cooling condition.

[0105] According to an exemplary embodiment of the present invention, the number of daily operations under the third cooling condition and the number of daily operations under the fourth cooling condition may be set differently. According to an exemplary embodiment of the present invention, the number of daily operations under the third cooling condition may be set to be less than the number of daily operations under the fourth cooling condition.

[0106] As a detailed example, when the predetermined difference for the difference between the SOH of the battery of the present vehicle and the reference SOH of the present vehicle is 3%, and when the second temperature is 40 degrees Celsius, the processor 110 may reduce the temperature of the battery according to the third cooling condition as follows.

[0107] When it is recognized that the degree to which the SOH of the battery of the present vehicle is less than the reference SOH of the present vehicle is less than 3%, and when the temperature of the battery is measured to be greater than 40 degrees Celsius while the vehicle is not in a driving state, the processor 110 may reduce the temperature of the battery according to the third cooling condition for cooling the coolant once every hour, up to once a day, until the temperature of the battery reaches 30 degrees Celsius.

[0108] According to an exemplary embodiment of the present invention, the processor 110 may be configured to control the coolant to reduce the temperature of the battery according to a fourth cooling condition based on identifying that the degree to which the SOH of the battery is less than the reference SOH of the vehicle is greater than or equal to a predetermined difference and identifying that the temperature of the battery is greater than a second temperature when the vehicle is in a driving state.

[0109] As a detailed example, when the predetermined difference is 3% for the difference between the SOH of the vehicle's battery and the reference SOH of the vehicle, and when the second temperature is 40 degrees Celsius, the processor 110 may reduce the temperature of the battery as follows according to the fourth cooling condition.

[0110] When it is identified that the degree to which the SOH of the vehicle's battery is less than the reference SOH of the vehicle is greater than or equal to 3%, and when the temperature of the battery is measured to be greater than 40 degrees Celsius when the vehicle is in a non-driving state, the processor 110 may reduce the temperature of the battery according to the fourth cooling condition for cooling the coolant once every hour, up to twice a day, until the temperature of the battery is 30 degrees Celsius.

[0111] According to an exemplary embodiment of the present invention, based on identifying that the degree to which the SOH of the battery is less than the reference SOH of the vehicle is less than a predetermined difference, the processor 110 may reduce the output of the battery in a driving state of the vehicle according to a first output condition as compared with the output of the battery when the SOH of the vehicle's battery is not less than the reference SOH of the vehicle.

[0112] According to an exemplary embodiment of the present invention, when the vehicle is driving, the processor 110 may be configured to control the output of the battery according to a first output condition or a second output condition.

[0113] For example, the output of the battery according to the first output condition when the vehicle is driving may be set to be less than the output of the battery according to the second output condition when the vehicle is driving, or the maximum output of the battery according to the first output condition may be set to be less than the maximum output of the battery according to the second output condition. In other words, the burden on the SOH of the battery when controlling the output of the battery according to the second output condition may be further reduced compared with the burden on the SOH of the battery when controlling the output of the battery according to the first output condition.

[0114] As a detailed example, when the predetermined difference is 3% for the difference between the SOH of the vehicle's battery and the reference SOH of the vehicle, the processor 110 may reduce the output of the battery as follows according to the first output condition.

[0115] When the degree to which the SOH of the vehicle's battery is less than the reference SOH of the vehicle is less than 3% and when the vehicle is in motion, the processor 110 may reduce the output of the battery by 10% compared to when the SOH of the vehicle's battery is not less than the reference SOH of the vehicle, or may reduce the maximum output of the vehicle's battery by 10%.

[0116] According to an exemplary embodiment of the present invention, based on recognizing that the degree to which the SOH of the battery is less than the reference SOH of the vehicle is greater than or equal to a predetermined difference, the processor 110 may, in a state where the vehicle is in motion, reduce the output of the battery according to a second output condition as compared to the output of the battery when the SOH of the vehicle's battery is not less than the reference SOH of the vehicle.

[0117] As a detailed example, for the difference between the SOH of the vehicle's battery and the reference SOH of the vehicle, when the predetermined difference is 3%, the processor 110 may reduce the output of the battery according to the second output condition as follows.

[0118] When the degree to which the SOH of the vehicle's battery is less than the reference SOH of the vehicle is greater than or equal to 3% and when the vehicle is in motion, the processor 110 may reduce the output of the battery by 15% compared to the output of the battery when the SOH of the vehicle's battery is not less than the reference SOH of the vehicle, or may reduce the maximum output of the vehicle's battery by 15%.

[0119] According to an exemplary embodiment of the present invention, the content included in the first heating condition, the second heating condition, the first cooling condition, the second cooling condition, the third cooling condition, the fourth cooling condition, the first output condition, or the second output condition may be set according to the control amount required to match the SOH of the vehicle's battery with the reference SOH of the vehicle.

[0120] For example, for the amount of remaining energy in the vehicle's battery, the amount of energy required to preheat the vehicle, etc., the control amount required to match the SOH of the vehicle's battery with the reference SOH of the vehicle may be determined.

[0121] For example, when the amount of remaining energy in the vehicle's battery is less than a predetermined amount, or when the amount of energy required to preheat the vehicle is large, the control amount of the temperature of the battery or the output of the battery may be set differently.

[0122] As a detailed example, when the degree to which the SOH of the battery is less than the reference SOH of the vehicle is less than the predetermined difference, although the processor 110 should reduce the maximum output of the battery by 10% according to the first output condition, when the amount of remaining energy in the vehicle's battery is small, the processor 110 may reduce the highest output of the battery by 15%.

[0123] According to an exemplary embodiment of the present invention, when it is recognized that the state of health (SOH) of the vehicle battery is less than the reference SOH of the vehicle, the processor 110 may provide information related to the SOH of the vehicle battery to the user.

[0124] For example, the processor 110 may provide information related to the SOH of the vehicle battery through the infotainment device of the vehicle. As a detailed example, the user may recognize information related to the SOH of the battery through the display device, audio, etc. of the vehicle.

[0125] According to an exemplary embodiment of the present invention, when it is recognized that the SOH of the vehicle battery is less than the reference SOH of the vehicle, the processor 110 may provide at least one notification for selecting whether to control the temperature of the battery or the output of the battery or any combination thereof. For example, the processor 110 may provide a notification for asking the user whether to control the temperature of the battery or the output of the battery through the infotainment device of the vehicle. As a detailed example, the user may select whether to control the temperature of the battery or the output of the battery through the touch display device, input device, microphone, etc. of the vehicle.

[0126] According to an exemplary embodiment of the present invention, when it is recognized that the SOH of the vehicle battery is less than the reference SOH of the vehicle, the processor 110 may provide at least one notification for suggesting whether to control the temperature of the battery or the output of the battery or any combination thereof.

[0127] According to an exemplary embodiment of the present invention, depending on receiving information related to the SOH of the vehicle battery from the processor 110 and directly selecting whether to control the temperature of the battery or the output of the battery, the user can easily manage the durability and safety of the vehicle battery.

[0128] According to an exemplary embodiment of the present invention, when the temperature of the battery reaches a temperature at which the battery performance does not deteriorate, the processor 110 may end the control of at least one of the temperature of the battery or the output of the battery or any combination thereof.

[0129] For example, the temperature at which the battery performance does not deteriorate may include a range between a first temperature and a second temperature. As a detailed example, the appropriate temperature range for the battery performance not to deteriorate may be set to a temperature between 10 degrees Celsius and 30 degrees Celsius. The appropriate temperature range may be set differently according to the driving environment or system of the vehicle.

[0130] For example, when the temperature of the vehicle battery reaches the appropriate temperature range by controlling the temperature of the battery or the output of the battery, the processor 110 may end the control of the temperature of the battery or the output of the battery for energy efficiency or to prevent unnecessary control.

[0131] According to an exemplary embodiment of the present invention, when the SOH of the battery reaches the reference SOH of the vehicle, the processor 110 may end the control of at least one of the temperature of the battery, the output of the battery, or any combination thereof.

[0132] For example, the processor 110 may be configured to control the temperature of the battery or the output of the battery according to set control conditions (such as heating conditions, cooling conditions, output conditions, etc.).

[0133] For example, when the SOH of the battery reaches the reference SOH of the vehicle, the processor 110 may end the control of the temperature of the battery or the output of the battery for energy efficiency or to prevent unnecessary control.

[0134] Figure 2 It is a graph showing an example of matching the SOH of the vehicle that is less than the reference SOH of the vehicle before controlling the battery with the reference SOH of the vehicle after controlling the battery in a vehicle control device according to an exemplary embodiment of the present invention.

[0135] Referring to the Figure 2 graph according to an exemplary embodiment of the present invention, the vertical axis may refer to the SOH, and the horizontal axis X may refer to the cumulative driving distance of the vehicle, the usage duration of the battery, or the life cycle of the battery. For example, the longer the cumulative driving distance of the vehicle, the usage duration of the battery, or the life cycle of the battery, the more the SOH of the vehicle battery may decrease.

[0136] Referring to the Figure 2 graph before controlling the battery in according to an exemplary embodiment of the present invention, depending on the driving environment of the vehicle or the driving characteristics of the driver of the vehicle, the degree of decrease in the SOH of the vehicle battery may be greater than the degree of decrease in the reference SOH of the vehicle. In this case, control for managing the SOH of the vehicle battery may be required.

[0137] Referring to the Figure 2 graph after controlling the battery in according to an exemplary embodiment of the present invention, the temperature of the battery or the output of the battery may be controlled to optimize the SOH of the vehicle battery so that the SOH of the vehicle battery matches the reference SOH of the vehicle.

[0138] For example, when continuously controlling the temperature of the battery or the output of the battery, as the cumulative driving distance of the vehicle and the like increase, the vehicle control device according to an exemplary embodiment of the present invention may increase the SOH of the vehicle battery to the point P corresponding to the reference SOH of the vehicle.

[0139] According to Figure 2, according to an exemplary embodiment of the present invention, even though the SOH of the vehicle battery has decreased more than the reference SOH of the vehicle, the temperature or output of the battery can be controlled to optimize the SOH of the vehicle battery so that the SOH of the vehicle battery matches the reference SOH of the vehicle.

[0140] Figure 3 FIG. is a schematic diagram showing an example of the relationship between a vehicle control unit (VCU), a battery management unit (BMU), and an infotainment device that interact with each other according to an exemplary embodiment of the present invention.

[0141] According to an exemplary embodiment of the present invention, the VCU 300 can send and receive data together with the BMU 301 and the infotainment device 302.

[0142] For example, when the SOH of the vehicle battery is less than the reference SOH of the vehicle, the BMU 301 can send data associated with the SOH of the vehicle battery corresponding to the reference SOH of the vehicle to the VCU 300.

[0143] For example, when it is recognized that the SOH of the vehicle battery is less than the reference SOH of the vehicle, the VCU 300 can transmit data about the SOH of the vehicle battery to the user.

[0144] For example, the infotainment device 302 can provide data about the SOH of the vehicle battery through the display device 303. In addition, the infotainment device 302 can provide a notification for asking whether to control the temperature or output of the battery to optimize the SOH of the vehicle battery to the user through the display device 303. In this case, the user can use a touch display device, a microphone, other input devices, etc. to select whether to control the temperature or output of the battery.

[0145] For example, the infotainment device 302 can send the result of the user's selection of whether to control the temperature or output of the battery to the VCU 300. The VCU 300 can be configured to control the temperature or output of the battery according to the result of the user's selection.

[0146] According to Figure 3 , according to an exemplary embodiment of the present invention, the VCU 300 can receive data associated with the SOH of the vehicle battery corresponding to the reference SOH of the vehicle from the BMU 301, and can provide the data associated with the SOH of the vehicle battery to the user through the infotainment device 302, thereby allowing the user to directly select the control of the temperature or output of the battery.

[0147] Figure 4 FIG. is a flowchart showing a vehicle control device or a vehicle control method according to an exemplary embodiment of the present invention.

[0148] According to an exemplary embodiment of the present invention, at S410, the processor may compare the reference SOH of the present vehicle corresponding to the present vehicle with the SOH of the battery of the present vehicle among the states of health (SOH) of each vehicle type obtained by evaluating the durability of the battery of each vehicle type.

[0149] According to an exemplary embodiment of the present invention, at S420, the processor may identify whether the SOH of the battery of the present vehicle is less than the reference SOH of the present vehicle corresponding to the present vehicle among the SOH of each vehicle type obtained by evaluating the durability of the battery of each vehicle type.

[0150] For example, since there is no need to optimize the SOH of the battery of the present vehicle when the SOH of the battery of the present vehicle is not less than the reference SOH of the present vehicle, at S410, the processor may continuously perform monitoring for comparing the reference SOH of the present vehicle with the SOH of the battery of the present vehicle.

[0151] For example, since it is necessary to optimize the SOH of the battery of the present vehicle when the SOH of the battery of the present vehicle is less than the reference SOH of the present vehicle, at S430, the processor is configured to control the temperature of the battery or the output of the battery. In this case, the processor may provide a notification for asking the user whether to control the temperature of the battery or the output of the battery.

[0152] Figure 5 It is a flowchart for describing an example of changing a battery control mode according to the degree to which the SOH of the present vehicle is less than the reference SOH of the present vehicle in a vehicle control device or a vehicle control method according to an exemplary embodiment of the present invention.

[0153] According to an exemplary embodiment of the present invention, at S510, the processor may store the reference SOH of each vehicle type in the battery management system (BMS) of the present vehicle. For example, the reference SOH of each vehicle type may be stored in the memory of the vehicle control device.

[0154] According to an exemplary embodiment of the present invention, at S520, the processor may monitor the SOH of the battery of the present vehicle. For example, the processor is configured to determine or predict the SOH of the battery of the present vehicle based on at least one of the charging capacity when the battery is charged, the charging energy when the battery is charged, the voltage drop of each output of the battery when the vehicle is running, or the discharge energy of the battery, or any combination thereof.

[0155] For example, the processor may identify the SOH of each vehicle type corresponding to the current SOH of the battery of the present vehicle among the SOH of each vehicle type as the "reference SOH of the present vehicle".

[0156] According to an exemplary embodiment of the present invention, the processor may compare the SOH of the vehicle battery with the reference SOH of the vehicle. For example, in S530, the processor is configured to determine whether the SOH of the vehicle is less than the reference SOH of the vehicle. At this time, since it is not necessary to optimize the SOH of the vehicle battery when the SOH of the vehicle battery is not less than the reference SOH of the vehicle, in S520, the processor may continuously perform monitoring for comparing the reference SOH of the vehicle with the SOH of the vehicle battery.

[0157] According to an exemplary embodiment of the present invention, when the SOH of the vehicle battery is less than the reference SOH of the vehicle, in S540, the processor is configured to determine whether the degree to which the SOH of the vehicle battery is less than the reference SOH of the vehicle is less than a predetermined difference. For example, the predetermined difference may be set to the following value: which is used to divide the number of times or methods for controlling the temperature of the battery or the number of times or methods for controlling the output of the battery to optimize the SOH of the vehicle battery.

[0158] According to an exemplary embodiment of the present invention, the processor may distinguish battery control modes according to the degree to which the SOH of the vehicle battery is less than the reference SOH of the vehicle being less than a predetermined difference.

[0159] According to an exemplary embodiment of the present invention, in S552, when the degree to which the SOH of the vehicle battery is less than the reference SOH of the vehicle is less than a predetermined difference, the processor may prepare a first battery control mode. For example, when preparing the first battery control mode, in S562, the processor may provide a notification to the user as to whether to utilize the first battery control mode. In this case, the processor may provide a notification to the user as to whether to utilize the first battery control mode through a display device of the vehicle or the like.

[0160] According to an exemplary embodiment of the present invention, in S572, the user may select whether to utilize the first battery control mode. When the user does not utilize the first battery control mode, in S520, the processor is configured to continue monitoring the SOH of the vehicle battery without controlling the temperature of the battery or the output of the battery.

[0161] According to an exemplary embodiment of the present invention, when the user utilizes the first battery control mode, in S582, the processor may heat or cool the coolant to control the temperature of the battery or control the output of the battery.

[0162] For example, the first battery control mode may be set to control the temperature of the battery with the coolant up to once a day. In addition, for example, the first battery control mode may be set to reduce the output of the battery by 10%.

[0163] According to an exemplary embodiment of the present invention, at S592, the processor is configured to determine whether the SOH of the vehicle battery is greater than or equal to the reference SOH of the vehicle, or whether the condition for ending the battery control mode is satisfied.

[0164] For example, when the SOH of the vehicle battery is greater than or equal to the reference SOH of the vehicle, the processor may end the battery control mode. For example, when the SOH of the vehicle battery is not greater than or equal to the reference SOH of the vehicle, at S582, the processor is configured to control the temperature of the battery or the output of the battery according to the first battery control mode.

[0165] For example, when the condition for ending the battery control mode is satisfied, the processor may end the battery control mode.

[0172] For example, the second battery control mode may be set to control the temperature of the battery using the coolant up to twice a day. In addition, for example, the second battery control mode may be set to reduce the output of the battery by 15%.

[0173] According to an exemplary embodiment of the present invention, at S594, the processor is configured to determine whether the SOH of the vehicle battery is greater than or equal to the reference SOH of the vehicle, or whether the condition for ending the battery control mode is satisfied.

[0174] For example, when the SOH of the vehicle battery is greater than or equal to the reference SOH of the vehicle, the processor may end the battery control mode. For example, when the SOH of the vehicle battery is not greater than or equal to the reference SOH of the vehicle, at S584, the processor is configured to control the temperature or output of the battery according to the second battery control mode.

[0175] For example, when the condition for ending the battery control mode is satisfied, the processor may end the battery control mode. The condition for ending the battery control mode may include a situation where, although the temperature or output of the battery is controlled, it is determined that it is difficult to match the SOH of the vehicle battery with the reference SOH of the vehicle. As a detailed example, the condition for ending the battery control mode may include a situation where, although the vehicle has traveled a predetermined driving distance or a longer driving distance while controlling the temperature or output of the battery, the SOH of the vehicle battery has not changed.
