The present disclosure relates to a battery management system, and more specifically, to a method and apparatus for diagnosing an abnormal voltage drop in an eco-friendly battery.
Eco-friendly vehicles such as hybrid electronic vehicle (HEV), plug-in HEV (PHEV), and electronic vehicle (EV) have a built-in battery, which is a storage device to store electrical energy, to drive the motor. These vehicles have built-in high-voltage batteries that are different from the low-voltage batteries provided in conventional internal combustion engine vehicles.
As these high-voltage batteries become increasingly dense and high-energy, even minor quality issues can lead to dangerous situations such as fire. Therefore, battery safety becomes increasingly important.
The safety logic of a conventional high-voltage battery has a diagnostic logic to detect an abnormal drop in battery voltage when the deviation of cell voltages is maintained at a certain level for a certain time period or when the cell voltages are maintained at a certain level for a certain time period. However, in the high-voltage battery of a specific vehicle, a voltage drop occurs that exceeds the range of the diagnostic logic used to detect the voltage drop. However, when a voltage drop exceeds the range of this diagnostic logic occurs, it is determined to be a voltage sensing error, and the abnormal voltage drop cannot be detected.
Therefore, in the present field of the present disclosure, there is a demand for a diagnostic logic that can detect an abnormal voltage drop even when the cell voltage drops rapidly.

In the conventional battery cell abnormality diagnosis logic, if the voltage deviation of a specific cell remains above a threshold for a certain time period or the voltage of a specific cell maintains a constant value for a certain time period, it is diagnosed that an abnormality has occurred in the cell.
For example, if the voltage deviation of a cell maintains 1V for 5 seconds or the voltage of a cell maintains 1.5V for more than 5 seconds, it may be diagnosed that an abnormality has occurred in the cell.

However, in the conventional battery cell abnormality diagnosis logic, during the first period 110, the voltage deviation of the cell does not maintain 1V for more than 5 seconds, so it is not diagnosed that abnormality has occurred in the cell. During the second period 130, it is determined to be a voltage sensing error in a sensor and is not diagnosed as occurrence of cell abnormality, so that the cell abnormality is not diagnosed.
Hereinafter, the present disclosure proposes an apparatus and method that can diagnose the occurrence of the above phenomenon as a cell voltage deviation rather than determining it as a voltage sensing error in the sensor.

The battery 310 stores power energy for driving a vehicle and includes a plurality of cells.
The battery management unit 330 stores the maximum and minimum values of voltage measured in all cells forming the battery 310 during a one-cycle discharge period of the battery 310 when a vehicle is in an ignition on (IG ON) mode.
The reason for storing the maximum and minimum values of the voltage measured in all cells as described above is to prevent misdiagnosis due to voltage sensing abnormality.
In the instant case, the one-cycle discharge period may be defined as a time period until the vehicle switches from an ignition on (IG ON) mode to an ignition off (IG OFF) mode, or a time period until the battery 310 is charged after the vehicle switches to the ignition OFF mode.
Furthermore, although not illustrated in the drawing, the battery management unit 330 may store the maximum and minimum values of the voltage measured in all cells forming the battery 310 in a built-in memory or memory associated with the battery management unit 330.
In the instant case, the battery management unit 330 may store the maximum and minimum values of the voltage measured in all cells forming the battery 310 only when the discharge current amount of the battery 310 during the one-cycle discharge period of the battery 310 is greater than or equal to a threshold current amount, and perform the following operation for diagnosing the cell voltage deviation abnormality or operating a cell low voltage.
In the instant case, the reason for storing the maximum and minimum voltage values only when the discharge current amount of the battery 310 is greater than or equal to a threshold current amount is to prevent the battery 310 from misdiagnosing a cell voltage deviation due to a high load current.
In the instant case, the threshold current amount may be any current amount, for example, 0.5C.
Furthermore, the battery management unit 330 is configured to determine occurrence of voltage deviation abnormality in a specific cell of the battery 310 when in the corresponding cell, a voltage deviation occurs at or above a first threshold voltage a threshold number of times or more than the threshold number during a one-cycle discharge period of the battery 310, and stores the identifier (ID) or unique number (ID Number) of the cell in which the voltage deviation abnormality is occurred in the built-in memory or memory associated with the battery management unit 330.
In the instant case, the voltage deviation may be defined as a voltage difference between the immediately preceding maximum or minimum value of the voltage measured in the cell and the maximum or minimum value of the voltage measured to a current point. If the voltage deviation greater than or equal to the first threshold voltage occurs once, it is possible to count whether a new voltage deviation is occurred based on the voltage measured from the current point.

In the instant case, the emergency allowable power may be set to arbitrary power depending on the type of battery 310 or type of vehicle, and may be set to 10 KW, for example.
In addition, if it is determined that the voltage deviation abnormality has occurred in the cell, the battery management unit 330 may transmit a warning message to the driver of the vehicle and transmit information related to the occurrence of an abnormality in the battery 310 to the vehicle control unit 370.
In the instant case, the warning message may be transmitted through the vehicle's display screen or vehicle's speakers.
Furthermore, the battery management unit 330 does not diagnose a voltage sensing error but determines that low voltage abnormality has occurred in a specific cell of the battery 310 when the voltage of the corresponding cell is maintained at or below a second threshold voltage for a threshold time period during the one-cycle discharge period of the battery 310.
In the instant case, the second threshold voltage may be set to any value, for example, 0.5V.
Furthermore, the threshold time period may be set to any time, for example, 1 second.
In the instant case, the battery management unit 330 may limit the output and charging of the battery 310 if it is determined that the low voltage abnormality has occurred in the cell.
For example, if it is determined that the low voltage abnormality has occurred in the cell, the battery management unit 330 may limit the output of the battery 310 to the emergency allowable power or less and restrict the charging of the battery 310 for safety reasons.
For example, when attempting to charge the battery 310 when it is determined that the low voltage abnormality has occurred in the cell, the driver may be warned through the vehicle's speaker or display that the battery 310 cannot be charged.
In the instant case, the emergency allowable power may be set to any power depending on the type of battery 310 or type of vehicle, and may be set to 10 KW, for example.
In the instant case, when the low voltage abnormality has occurred in the cell, the battery management unit 330 may transmit a warning message to the driver of the vehicle and transmit information related to the occurrence of the low voltage abnormality in the cell of the battery 310 to the vehicle control unit 370.
The sensor unit 350 measures the voltage of the battery 310.
In the instant case, the sensor unit 350 may measure all changes in the voltages of cells forming the battery 310.
The vehicle control unit 370 is configured to control the vehicle based on the output of the battery 310.
In the instant case, the vehicle control unit 370 receives information related to the occurrence of the low voltage abnormality in the cell of the battery 310 from the battery management unit 330 and is configured to control the vehicle based on the present information.
For example, when the vehicle control unit 370 receives information related to the occurrence of the low voltage abnormality in the cell of the battery 310 from the battery management unit 330, it gradually reduces the speed of the vehicle or controls the vehicle to evacuate to a safe place.
