IN-CELL SHORTCIRCUIT DETECTION DEVICE AND METHOD AND CELL PACK |
摘要 |
A battery internal short-circuit detection apparatus includes: a voltage detection unit for detecting a terminal voltage of the battery; a current detection unit for detecting a discharging current of the battery; a voltage drop and recovery detection unit for detecting a momentary voltage drop of the battery and a recovery from the voltage drop, in response to a result of detection performed by the voltage detection unit; and a determination unit for determining that an internal short circuit has occurred, when a maximum value of the discharging current detected by the current detection unit between the voltage drop and the recovery is equal to or lower than a threshold current. |
