[0002] This application claims the benefit of Korean Patent Application No. 10-2020-0090816, filed on July 22, 2020, with the Korean Intellectual Property Office, the disclosure of which is incorporated herein by reference. Technical Field

[0003] This disclosure relates to a vehicle and a method for controlling the same. Specifically, this disclosure relates to sensing the battery state of a vehicle and determining an appropriate charging mode. Background Technology

[0004] The existing vehicle battery charging method is a simple method to determine whether the battery is discharged and to uniformly charge it for a fixed time with a fixed voltage when a discharge mark is generated due to dark current.

[0005] However, in existing technologies, because the battery's discharge history cannot be determined, it is impossible to know why the battery discharged. Therefore, there is a problem in determining the appropriate battery charging mode. Summary of the Invention

[0006] Therefore, one aspect of this disclosure provides a vehicle that determines the cause of battery discharge and proposes an appropriate charging mode based on the cause of discharge. Another aspect of this disclosure provides a control method for the vehicle.

[0007] Furthermore, another aspect of this disclosure provides a vehicle for determining the discharge history of a battery and the cause of battery discharge. Yet another aspect of this disclosure provides a control method for the vehicle.

[0008] According to one aspect of this disclosure, a vehicle includes: a battery; a sensing device configured to sense at least one of a charging state, a discharging state, and a performance state of the battery; a display configured to display the state of the battery; and a controller configured to determine the cause of battery discharge based on the sensing result of the sensing device, determine at least one of a charging voltage, a charging current, and a charging time of the battery based on the determination result, and control the display to display the charging mode of the battery based on the determined charging voltage, charging current, or charging time.

[0009] The controller can be configured to calculate the battery’s internal resistance, total discharge amount, discharge sequence, discharge time or average discharge current, and control the display to show the battery’s charging mode based on the calculation results.

[0010] The controller can be configured to determine the battery's discharge history. When a battery's discharge history is determined, the controller can be configured to determine the battery's discharge time and discharge amount based on that history.

[0011] The controller can be configured to determine whether the battery discharge time is equal to or shorter than a preset time. When it is determined that the battery is discharging within a time equal to or shorter than the preset time, the controller can determine a charging mode by setting the charging voltage to a first charging voltage, the charging current to a first charging current, and the charging time to a first charging time, and control the display to show the determined charging mode.

[0012] The controller can be configured to determine whether the battery discharge time is longer than a preset time. When it is determined that the battery is discharging for longer than the preset time, the controller can be configured to determine a charging mode by setting the charging voltage to a second charging voltage, the charging current to a second charging current, and the charging time to a second charging time, and control the display to show the determined charging mode.

[0013] The vehicle may further include a storage device configured to store charging mode information. The controller may be configured to store the charging mode in the storage device.

[0014] The vehicle may further include: a power supply unit configured to supply power to the battery. The controller is configured to control a display to show a forced discharge warning signal from the power supply unit based on a judgment result.

[0015] The controller can be configured to control the display based on the judgment result to show the vehicle's discharge warning or the discharge warning signal of an external electronic device installed in the vehicle.

[0016] The controller can be configured to compare the battery's state of performance (SOP) value with the SOP value of the battery in its fully charged state. When it is determined that the battery's SOP value has a value equal to or greater than a reference ratio of the battery's SOP value in its fully charged state, the controller can be configured to determine a charging mode by setting the charging voltage to a third charging voltage, the charging current to a third charging current, and the charging time to a third charging time, and control the display to show the determined charging mode.

[0017] The controller can be configured to compare the current value of the internal resistance with the initial value of the internal resistance. When it is determined that the current value of the internal resistance is greater than the initial value, the controller can be configured to determine the charging mode by setting the charging voltage to a fourth charging voltage, the charging current to a fourth charging current, and the charging time to a fourth charging time, and control the display to show the determined charging mode.

[0019] Control may include: calculating the battery’s internal resistance, total discharge amount, discharge sequence, discharge time, or average discharge current; and controlling a display based on the calculation results to show the battery’s charging mode.

[0020] The control may include: determining the battery's discharge history. The control may also include: when a battery discharge history is determined to exist, determining the battery's discharge time and discharge amount based on the discharge history.

[0021] The control may include: determining whether the battery discharge time is equal to or shorter than a preset time; when it is determined that the battery is discharging within a time equal to or shorter than the preset time, determining the charging mode by setting the charging voltage to a first charging voltage, the charging current to a first charging current, and the charging time to a first charging time; and displaying the determined charging mode.

[0022] The control may include: determining whether the battery discharge time is longer than a preset time; when it is determined that the battery is discharging for a longer than preset time, determining the charging mode by setting the charging voltage to a second charging voltage, the charging current to a second charging current, and the charging time to a second charging time; and displaying the determined charging mode.

[0023] The control method may further include storing charging mode information, and the control may include storing the charging mode in a storage device.

[0024] The control method may further include supplying power to the battery, and the control may include controlling the display to show a forced discharge warning signal of the power supply device based on the judgment result.

[0025] Control may include: controlling the display to show a discharge warning signal for the vehicle or a discharge warning signal for an external electronic device located in the vehicle, based on the judgment result.

[0026] Control may include: comparing the battery's performance state with the performance state of the battery in a fully charged state; when it is determined that the battery's performance state is equal to or greater than a reference ratio of the battery's performance state in a fully charged state, determining a charging mode by setting the charging voltage to a third charging voltage, the charging current to a third charging current, and the charging time to a third charging time; and displaying the determined charging mode.

[0027] The control may include: comparing the current value of the internal resistance with the initial value of the internal resistance; when it is determined that the current value of the internal resistance is greater than the initial value of the internal resistance, determining the charging mode by setting the charging voltage to a fourth charging voltage, the charging current to a fourth charging current, and the charging time to a fourth charging time; and displaying the determined charging mode.

[0051] However, the sensors included in the sensing device 100 are not limited to battery sensors, and may include other components capable of sensing the charging state, performance state or discharge state of the battery 2.

[0071] Corresponding to Figure 1 and Figure 2 The performance of the components of the vehicle 1 shown can be improved by adding or removing at least one component. Furthermore, those skilled in the art should readily understand that the relative positions of the components can vary depending on the system's performance or structure.

[0072] at the same time, Figure 1 and Figure 2 Each component shown can represent software and / or hardware components such as field-programmable gate arrays (FPGAs) and application-specific integrated circuits (ASICs).

[0073] The following describes the process by which the controller 200 determines the charging mode of the battery 2.

[0074] Figure 3 This is a diagram illustrating the process by which a controller determines the charging mode of a battery according to an embodiment of the present disclosure.

[0075] The controller 200 of the disclosed embodiment determines whether the vehicle 1 is started (2101).

[0076] When it is determined that vehicle 1 is started, sensing device 100 senses the charging state, discharging state, or performance state of battery 2. Controller 200 receives the sensing results (2102) from sensing device 100.

[0077] Specifically, the state of charge, state of discharge, or performance status of battery 2 may include the internal resistance of battery 2, total discharge amount, discharge sequence, discharge time, or average discharge current. However, the state of charge, state of discharge, or performance status information of battery 2 is not limited to this.

[0078] The controller 200 can calculate the internal resistance, total discharge amount, discharge sequence, discharge time, or average discharge current of the battery 2 based on the received charging state, discharging state, or performance state information of the battery 2 (2103).

[0079] When determining the charging state, discharging state, or performance state information of battery 2, controller 200 determines whether there is a discharge history of battery 2 (2104).

[0080] If it is determined that there is a discharge history of battery 2, the controller 200 determines and identifies the charging mode of the battery (2105, 2106). However, if it is determined that there is no discharge history of battery 2, the controller 200 terminates the determination process.

[0081] The following describes Figure 4 At the same time, describe the detailed process of determining the charging mode of battery 2.

[0082] Figure 4 This is a diagram illustrating the process by which a controller determines the charging mode of a battery according to an embodiment of the present disclosure.

[0083] According to the disclosed embodiment, the controller 200 can determine the charging mode (2201) of the battery 2.

[0084] The controller 200 quantifies the performance state of the battery 2 and can compare the current performance state value of the battery 2 with the performance state value when the battery 2 is fully charged (2202).

[0085] According to one disclosed embodiment, when it is determined that the current state of performance of battery 2 is less than 1% of the state of performance of battery 2 when it is fully charged, controller 200 compares the current internal resistance of battery 2 with the initial internal resistance of battery 2 (2203).

[0086] However, when it is determined that the current state of performance of battery 2 is equal to or greater than 1% of the state of performance of battery 2 when it is fully charged, controller 200 determines the charging mode of battery 2 (2206).

[0087] In this case, the controller 200 can determine the charging mode by setting the charging voltage to the third charging voltage, the charging current to the third charging current, and the charging time to the third charging time.

[0088] For example, the controller can determine the charging mode to set the third charging voltage to 14.8V, the third charging current to 50A, and the third charging time to charge to 85% of the battery 2's fully charged state. However, the charging mode information is not limited to this and can vary depending on the state and type of the battery 2.

[0089] When the controller 200 determines that the current internal resistance value of battery 2 is greater than the initial internal resistance value of battery 2, it determines that battery 2 is old and determines the charging mode of battery 2. However, when the controller 200 determines that the current internal resistance value of battery 2 is less than or equal to the initial internal resistance value of battery 2, it compares the discharge time of battery 2 with the discharge reference preset time and determines the charging mode of battery (2204, 2206).

[0090] Specifically, when it is determined that the internal resistance value of battery 2 is greater than the initial internal resistance value of battery 2, the controller 200 can determine the charging mode by setting the charging voltage to the fourth charging voltage, the charging current to the fourth charging current, and the charging time to the fourth charging time.

[0091] Here, "fourth" refers to the value set when it is determined that the internal resistance of battery 2 is greater than its initial internal resistance. However, this meaning can vary depending on the user's definition.

[0092] Here, the preset time is a standard or reference value used to determine whether battery 2 has experienced overcurrent discharge or overcharge. The preset time can vary depending on the type, capacity, lifespan, condition, or age of battery 2.

[0093] As a result of comparing the discharge time of battery 2 with the discharge reference preset time, when it is determined that battery 2 is discharging within a time equal to or shorter than (less than) the preset time, controller 200 can determine the charging mode by setting the charging voltage to the first charging voltage, the charging current to the first charging current, and the charging time to the first charging time.

[0094] For example, controller 200 can determine a charging mode to set a first charging voltage to 14.8V, a first charging current to 50A, and a first charging time to the time it takes for the internal resistance to reach 1.1 times its initial value.

[0095] However, the charging mode information is not limited to this and can vary depending on the state and type of battery 2.

[0096] In addition, the controller determines whether the discharge time of battery 2 is longer than (greater than) a preset time. When it is determined that battery 2 is discharging for a period of longer than (greater than) the preset time, the controller 200 can determine the charging mode by setting the charging voltage to a second charging voltage, the charging current to a second charging current, and the charging time to a second charging time.

[0097] For example, the controller 200 can determine the charging mode by setting the second charging voltage between 14.5V and 14.8V, the second charging current between 30A and 50A, and the second charging time between 1.5 hours and 2 hours. However, the charging mode information is not limited to this and can vary depending on the state and type of the battery 2.

[0098] Specifically, when it is determined that the discharge time of battery 2 is greater than a preset time but less than twice the preset time (i.e., less than twice the preset time), the controller 200 can determine the charging mode by setting the charging voltage to 14.5V, the charging current to 30A, and the charging time to 1.5 hours. However, the charging mode information is not limited to this and can vary depending on the state and type of battery 2.

[0099] Additionally, when it is determined that the discharge time of battery 2 is more than twice the preset time, the controller 200 can determine the charging mode by setting the charging voltage to 14.8V, the charging current to 50A, and the charging time to 1.5 hours. However, the charging mode information is not limited to this and can vary depending on the state and type of battery 2.

[0100] However, when it is determined that the discharge time of battery 2 is equal to or less than the preset time, controller 200 terminates the engine operation of vehicle 1 and ends the control process (2205).

[0101] Figure 5 This is a diagram illustrating the process by which a controller stores the discharge history of a battery according to an embodiment of the present disclosure.

[0102] As above Figure 3 and Figure 4 As described herein, the controller 200, according to the disclosed embodiment, determines and identifies the charging mode (2301, 2302) of the battery 2.

[0103] When the charging mode of battery 2 is determined, the controller 200 can store the discharge history of battery 2 used in the determination of the charging mode in the storage device 400 (2303).

[0104] Since the storage device 400 stores the discharge history of the battery 2, the disclosed embodiments enable the discharge history and discharge cause to be checked by the service center, and product quality to be improved by notifying the customer of the discharge of the battery 2.

[0105] Figure 6 This is a diagram illustrating the process by which a controller, according to an embodiment of the present disclosure, displays battery discharge information and issues a warning to a user.

[0106] As above Figure 3 and Figure 4 As described herein, the controller 200, according to the disclosed embodiment, determines and identifies the charging mode (2401, 2402) of the battery 2.

[0107] When the charging mode of battery 2 is determined, controller 200 analyzes the determined charging mode and controls display 300 to notify the user of the reason for battery 2's discharge. Additionally, controller 200 can control display 300 to display a charging, replacement, or forced discharge warning signal (2403) for battery 2. Furthermore, controller 200 can control display 300 to display a discharge warning for vehicle 1 or a discharge warning signal from an external electronic device installed in vehicle 1 based on the discharge time of battery 2.

[0108] Here, the notification or warning method may include a method of notifying the user through a display, head-up display (HUD), or human-machine interface (HMI) provided in the vehicle 1. However, the notification or warning method is not limited to this and may include a method of notifying the user of information related to the battery 2 in a visual or auditory manner.

[0109] The disclosed embodiments include the above configuration, thereby enabling the determination of the cause of battery discharge and the provision of an appropriate charging mode.

[0110] In addition, the disclosed embodiments include the above configuration, which allows the battery discharge history to be stored and the stored information to be shared with the service center, enabling vehicle users to take appropriate measures.

[0111] In addition, the disclosed embodiments include the above configuration, thereby charging the battery according to an appropriate charging mode and improving battery durability.

Here, the term "module" refers to, but is not limited to, software and / or hardware components that perform certain tasks, such as field-programmable gate arrays (FPGAs) or application-specific integrated circuits (ASICs).
